Scientists have uncovered new clues about a curious fossil site in Nevada, a graveyard for dozens of giant marine reptiles. Instead of the site of a massive die-off as suspected, it might have been an ancient maternity ward where the creatures came to give birth.

The site is famous for its fossils from giant ichthyosaurs — reptiles that dominated the ancient seas and could grow up to the size of a school bus. The creatures — the name means fish lizard — were underwater predators with large paddle-shaped flippers and long jaws full of teeth.

Since the ichthyosaur bones in Nevada were excavated in the 1950s, many paleontologists have investigated how all these creatures could have died together. Now, researchers have proposed a different theory in a study published Monday in the journal Current Biology.

“Several lines of evidence all kind of point towards one argument here: That this was a place where giant ichthyosaurs came to give birth,” said co-author Nicholas Pyenson, curator of fossil marine mammals at the Smithsonian National Museum of Natural History.

Once a tropical sea, the site — part of Nevada’s Berlin-Ichthyosaur State Park — now sits in a dry, dusty landscape near an abandoned mining town, said lead author Randy Irmis, a paleontologist at the University of Utah.

To get a better look at the massive skeletons, which boast vertebrae the size of dinner plates and bones from their flippers as thick as boulders, researchers used 3D scanning to create a detailed digital model, Irmis said.

They identified fossils from at least 37 ichthyosaurs scattered around the area, dating back about 230 million years. The bones were preserved in different rock layers, suggesting the creatures could have died hundreds of thousands of years apart rather than all at once, Pyenson said.

A major break came when the researchers spotted some tiny bones among the massive adult fossils, and realized they belonged to embryos and newborns, Pyenson said. The researchers concluded that the creatures traveled to the site in groups for protection as they gave birth, like today’s marine giants. The fossils are believed to be from the mothers and offspring that died there over the years.

“Finding a place to give birth separated from a place where you might feed is really common in the modern world — among whales, among sharks,” Pyenson said.

Other clues helped rule out some previous explanations.

Testing the chemicals in the dirt didn’t turn up any signs of volcanic eruptions or huge shifts to the local environment. And the geology showed that the reptiles were preserved on the ocean floor pretty far from the shore — meaning they probably didn’t die in a mass beaching event, Irmis said.

The new study offers a plausible explanation for a site that’s baffled paleontologists for decades, said Dean Lomax, an ichthyosaur specialist at England’s University of Manchester who was not involved with the research.

The case may not be fully closed yet but the study “really helps to unlock a little bit more about this fascinating site,” Lomax said.

Negotiators reached a historic deal at a U.N. biodiversity conference early Monday that would represent the most significant effort to protect the world’s lands and oceans and provide critical financing to save biodiversity in the developing world.

The global framework comes on the day the United Nations Biodiversity Conference, or COP15, is set to end in Montreal. China, which holds the presidency at this conference, released a new draft on Sunday that gave the sometimes-contentious talks much-needed momentum.

“We have in our hands a package which I think can guide us as we all work together to halt and reverse biodiversity loss and put biodiversity on the path to recovery for the benefit of all people in the world,” Chinese Environment Minister Huang Runqiu told delegates before the package was adopted to rapturous applause just before dawn. “We can be truly proud.”

The most significant part of the agreement is a commitment to protect 30% of land and water considered important for biodiversity by 2030, known as 30 by 30. Currently, 17% of terrestrial and 10% of marine areas are protected.

The deal also calls for raising $200 billion by 2030 for biodiversity from a range of sources and working to phase out or reform subsidies that could provide another $500 billion for nature. As part of the financing package, the framework asks for increasing to at least $20 billion annually by 2025 the money that goes to poor countries. That number would increase to $30 billion each year by 2030.

Financing emerged late in the talks and risked derailing an agreement. Several African countries held up the final deal for almost nine hours. They wanted the creation of a new fund for biodiversity but agreed to the creation of one under the pre-existing Global Environmental Facility (GEF).

“Creating a fund under the GEF is the best way to obtain something immediate and efficient,” said Christophe Béchu, France’s minister for ecological transition who headed its delegation, adding that a completely new fund would have taken several years to establish and deprived developing countries of immediate cash for biodiversity.

Then as the agreement was about to be adopted, Congo stood up and said it opposed the deal because it didn’t set up that special biodiversity fund to provide developing countries with $100 billion by 2030.

Huang swept aside the opposition and the documents that make up the framework were adopted. The convention’s legal expert ruled Congo never formally objected to the document. Several other African countries, including Cameroon and Uganda, sided to no avail with Congo and said they would lodge a complaint.

“Many of us wanted more things in the text and more ambition, but we got an ambitious package,” Canada’s Minister of Environment and Climate Change Steven Guilbeault said. “We have 30 by 30. Six months ago, who would have thought we could 30 by 30 in Montreal? We have an agreement to halt and reverse biodiversity loss, to work on restoration, to reduce the use of pesticides. This is tremendous progress.”

France’s Béchu called it a “historical deal.”

“It’s not a small deal. It’s a deal with very precise and quantified objectives on pesticides, on reduction of loss of species, on eliminating bad subsidies,” he said. “We double until 2025 and triple until 2030 the finance for biodiversity.”

The ministers and government officials from about 190 countries have mostly agreed that protecting biodiversity has to be a priority, with many comparing those efforts to climate talks that wrapped up last month in Egypt.

Climate change coupled with habitat loss, pollution and development have hammered the world’s biodiversity, with one estimate in 2019 warning that a million plant and animal species face extinction within decades — a rate of loss 1,000 times greater than expected. Humans use about 50,000 wild species routinely, and 1 out of 5 people of the world’s 8 billion population depend on those species for food and income, the report said.

But the government officials struggled for nearly two weeks to agree on what that protection looks like and who will pay for it.

The financing has been among the most contentious issues, with delegates from 70 African, South American and Asian countries walking out of negotiations Wednesday. They returned several hours later.

Brazil, speaking for developing countries during the week, said in a statement that a new funding mechanism dedicated to biodiversity should be established and that developed countries provide $100 billion annually in financial grants to emerging economies until 2030.

“All the elements are in there for a balance of unhappiness which is the secret to achieving agreement in U.N. bodies,” Pierre du Plessis, a negotiator from Namibia who is helping coordinate the African group, told The Associated Press before the vote. “Everyone got a bit of what they wanted, not necessarily everything they wanted.”

There were supporters of the framework who said it fell short in several areas.

The Wildlife Conservation Society and other environmental groups were concerned that the deal puts off until 2050 a goal of preventing the extinction of species, preserving the integrity of ecosystems and maintaining the genetic diversity within populations. They fear that timeline is not ambitious enough.

Some advocates also wanted tougher language around subsidies that make food and fuel so cheap in many parts of the world. The document only calls for identifying subsidies by 2025 that can be reformed or phased out and working to reduce them by 2030.

“The new text is a mixed bag,” Andrew Deutz, director of global policy, institutions and conservation finance for The Nature Conservancy, said. “It contains some strong signals on finance and biodiversity, but it fails to advance beyond the targets of 10 years ago in terms of addressing drivers of biodiversity loss in productive sectors like agriculture, fisheries and infrastructure and thus still risks being fully transformational.”

Hollywood Cat is no longer.

The Los Angeles area’s most famous mountain lion, an aged wild male feline sighted around the city’s Griffith Park, was euthanized Saturday, wildlife officials said.

For years, it was known to prowl around the hillside “Hollywood” sign visible around much of Los Angeles, a fitting setting for a celebrity cat.

It earned the nickname Hollywood Cat, but the mountain lion — estimated to be around 11 years old  — is officially called P-22.

State and federal wildlife officers decided earlier this month to capture it due to its erratic behavior, perhaps associated with being struck by a vehicle.

Veterinarians found “significant trauma” to its head, right eye and internal organs, California’s Department of Fish and Wildlife said in a statement.

The experts also found underlying health issues, including “irreversible kidney disease, chronic weight loss, extensive parasitic skin infection over his entire body and localized arthritis.”

“The most difficult, but compassionate choice was to respectfully minimize his suffering and stress by humanely ending his journey,” the statement said.

“Mountain lion P-22 has had an extraordinary life and captured the hearts of the people of Los Angeles and beyond.”

Euthanizing the cougar was a punch to the gut for game experts who had grown to love the animal.

“This really hurts,” said Chuck Bonham, director of the Department of Fish and Wildlife, when he announced P-22’s death, according to USA Today.

“It’s been an incredibly difficult several days.”

‘Our favorite celebrity’ 

Congressman Adam Schiff, who represents part of Los Angeles County, said he was “heartbroken” at P-22’s passing.

“He was our favorite celebrity neighbor, occasional troublemaker, and beloved L.A. mascot,” Schiff tweeted.

“But most of all he was a magnificent, wild creature, who reminded us that we are part of a natural world much bigger than ourselves.”

California Governor Gavin Newsom praised P-22’s “incredible journey” in a statement.

“P-22’s survival on an island of wilderness in the heart of Los Angeles captivated people around the world,” Newsom said.

Griffith Park, where P-22 lived for perhaps a decade, is hemmed in by freeways and urban sprawl. It is a nine-square-mile (23-square-kilometer) isolated patch of nature.

Experts marveled at how the wild cat got across either of two major Los Angeles freeways — the 405 and 101 — to get to Griffith Park as early as 2012.

Officials said they were not looking for the driver who hit it.

“This situation is not the fault of P-22, nor of a driver who may have hit him,” the California Department of Fish and Wildlife said.

“Rather, it is an eventuality that arises from habitat loss and fragmentation, and it underscores the need for thoughtful construction of wildlife crossings and well-planned spaces that provide wild animals room to roam.”

In a profile of P-22 done long before its death, the National Park Service lamented that Griffith Park is too small for a second cougar, and “it’s unlikely he will ever find love with a female lion.”

The cat’s renown was due to frequent sightings, video doorbell cameras and physical encounters.

A Facebook page in honor of the cougar has more than 20,000 followers.

Uganda on Saturday lifted a two-month lockdown on two districts at the epicenter of the country’s Ebola epidemic, amid cautious hope that the outbreak could end soon.

Since authorities declared an Ebola outbreak Sept. 20, the East African nation has registered 142 confirmed cases and 56 deaths, with the disease spreading to the capital, Kampala.

The two central districts at the heart of the outbreak, Mubende and Kassanda, were placed under lockdown by President Yoweri Museveni on Oct. 15.

But on Saturday, Vice President Jessica Alupo announced that the government was “lifting all movement restrictions and curfew in Mubende and Kassanda districts with immediate effect.”

The two hotspots were under a dusk-to-dawn curfew, with markets, bars and churches closed as well as personal travel banned.

“The lifting of the restrictions is based on the fact that currently there is currently no transmission, no contact under follow-up, no patients in the isolation facilities, and we are progressing well,” Alupo said in a televised address delivered on behalf of Museveni.

Ugandan authorities said last month that new cases were falling, and the last confirmed patient with the disease was discharged from hospital Nov. 30.

Alupa warned however that the government remained on “high alert” for any resurgence in cases.

The announcement came after local leaders in the two districts appealed last month for the lockdown to be lifted and implored the central government to provide aid to citizens hit hard by the curbs on business.

The outbreak has been caused by the Sudan strain of the virus, for which there is currently no vaccine.

Uganda earlier this month received its first shipment of trial vaccines against the Sudan strain, with more doses expected in the coming weeks.

They will be used in a so-called ring vaccination trial, where all contacts of confirmed Ebola patients, and contacts of contacts, are jabbed along with frontline and health workers.

However, the absence of active Ebola cases in recent days has held up the vaccine trials, according to international health experts working in Uganda.

According to the World Health Organization, an outbreak of the disease ends when there are no new cases for 42 consecutive days — twice the incubation period of Ebola.

Ebola spreads through bodily fluids. Common symptoms are fever, vomiting, bleeding and diarrhea.

Outbreaks are difficult to contain, especially in urban environments.

Negotiators at a United Nations biodiversity conference Saturday have still not resolved most of the key issues around protecting the world’s nature by 2030 and providing tens of billions of dollars to developing countries to fund those efforts.

The United Nations Biodiversity Conference, or COP15, is set to wrap up Monday in Montreal and delegates were racing to agree on language in a framework that calls for protecting 30% of global land and marine areas by 2030, a goal known as “30 by 30.” Currently, 17% of terrestrial and 10% of marine areas globally are protected.

They also have to settle on amounts of funding that would go to financing projects to create protected areas and restore marine and other ecosystems. Early draft frameworks called for closing a $700 billion gap in financing by 2030. Most of that would come from reforming subsidies in the agriculture, fisheries and energy sectors but there are also calls for tens of billions of dollars in new funding that would flow from rich to poor nations.

“From the beginning of the negotiations, we’ve been seeing systematically some countries weakening the ambition. The ambition needs to come back,” Marco Lambertini, the director general of WWF International said, adding that they needed a “clear conservation target” that “sets the world on a clear trajectory towards delivering a nature positive future.”

Steven Guilbeault, Canada’s minister of environment and climate change, expressed more optimism. Guilbeault told The Associated Press Saturday morning that he has heard “few people talk about red lines” and that means “people are willing to talk. People are willing to negotiate.”

“I’ve heard a lot of support for ambition from all corners of the world,” Guilbeault said. “Everyone wants to leave here with an ambitious agreement.”

Elizabeth Maruma Mrema, the executive secretary of the U.N. Convention on Biological Diversity, told reporters Saturday afternoon that she was encouraged by the progress especially around committing resources but that a deal had not been reached yet.

“The negotiating teams have more work to do. They have to turn promises made into plans, ambitions and actions,” she said.

The ministers and government officials from about 190 countries mostly agree that protecting biodiversity has to be a priority, with many comparing those efforts to climate talks that wrapped up last month in Egypt.

Climate change coupled with habitat loss, pollution and development have hammered the world’s biodiversity, with one estimate in 2019 warning that a million plant and animal species face extinction within decades — a rate of loss 1,000 times greater than expected. Humans use about 50,000 wild species routinely, and 1 out of 5 people of the world’s 8 billion population depend on those species for food and income, the report said.

But they are struggling to agree on what that protection looks like and who will pay for it.

The financing has been among the most contentious issues, with delegates from 70 African, South American and Asian countries walking out of negotiations Wednesday. They returned several hours later.

Brazil, speaking for developing countries, said in a statement that a new funding mechanism dedicated to biodiversity be established and that developed countries provide $100 billion annually in financial grants to emerging economies until 2030.

“You need a robust and ambitious package on finance that matches the ambition of the Global Biodiversity framework,” Leonardo Cleaver de Athayde, the head of the Brazilian delegation, told the AP.

“This will cost a lot of money to implement. The targets are extremely ambitious and cost a lot of money,” he continued. “The developing countries will bear a higher burden in implementing it because most biodiversity resources are to be found in developing countries. They need international support.”

The donor countries — the European Union and 13 countries — responded Friday with a statement promising to increase biodiversity financing. They noted they doubled biodiversity spending from 2010 to 2015 and committed to several billion dollars more in biodiversity funding since then.

Zac Goldsmith, the U.K.’s minister for Overseas Territories, Commonwealth, Energy, Climate and Environment, acknowledged the focus cannot only be on popular protection measures like the 30 by 30 goal.

“The 30 by 30 is a headline target, but you can’t deliver 30 by 30 without a whole range of other things being agreed as well,” he said. “We’re not gonna have 30 by 30 without finance. We’re not going to have it unless other countries do as Costa Rica has and break the link between agricultural productivity and land degradation and deforestation. And we’re not gonna be able to do any of these things if we don’t address … subsidies.”

Even protection targets are still being squabbled over. Many countries believe 30% is an admirable goal but some countries are pushing to water the language down to allow among other things sustainable activities in those areas that conservationists fear could result in destructive logging and mining. Others want language referencing ways to better manage the other 70% of the world that wouldn’t be protected.

Other disagreements revolve around how best to share the benefits from genetic resources and enshrining the rights of Indigenous groups in any agreement. Some Indigenous groups want direct access to funding and a voice in designating protected areas that impact Indigenous peoples.

“Any protected areas that affect Indigenous peoples need to have the free prior informed consent of Indigenous peoples, otherwise there will be the same old patters of Indigenous peoples being displaced by protected areas,” Atossa Soltani, the director of global strategy for the Amazon Sacred Headwaters Initiative, an alliance of 30 Indigenous nations in Ecuador and Peru working to working to permanently protect 86 million acres of rainforest, said in an email interview.

The other challenge is including language — similar to the Paris Agreement on climate change — that creates a stronger system to report and verify the progress countries make. Many point to the failures of the 2010 biodiversity framework, which saw only six of the 20 targets partially met by a 2020 deadline.

“It’s very important for parties to see what others are doing. It’s important for civil society, people like you to track our progress or sometimes unfortunately lack thereof,” Guilbeault said. “It’s an important tool to help keep our feet to the fire. If it’s effective on climate. We should have it on nature as well.”

 
…

Outside a funeral home in eastern Beijing, dozens of people were bundled up in parkas and hats against the freezing temperatures Friday evening as workers in full protective suits wheeled out coffins one by one.

When an employee with a clipboard shouted the name of the dead, a relative trundled up to the coffin to examine the body. One of the relatives told The Associated Press their loved one had been infected with COVID-19.

Deaths linked to the coronavirus are appearing in Beijing after weeks of China reporting no fatalities, even as the country is seeing a surge of cases.

That surge comes as the government last week dramatically eased some of the world’s strictest COVID-19 containment measures. On Wednesday, the government said it would stop reporting asymptomatic COVID-19 cases since they’ve become impossible to track with mass testing no longer required.

That halt in reporting made it unclear how fast the virus is spreading. Social media posts, business closures and other anecdotal evidence suggest huge numbers of infections.

It’s also unclear how many people are dying from the virus. An AP reporter who visited the Dongjiao Funeral home was told by relatives that at least two people cremated there had died after testing positive.

Health authorities had designated Dongjiao and one other funeral home to cremate those who die after testing positive, according to a relative of one of the dead. The woman said her elderly relative had fallen ill in early December, tested positive, and died Friday morning in an emergency ward.

She said there were lots of people in the emergency ward who had tested positive for COVID-19, adding that there weren’t enough nurses to take care of them. The woman did not want to be identified for fear of retribution.

Over about an hour, an AP reporter saw about a dozen bodies wheeled from the Dongjiao funeral home.

About a half-dozen people inside described how another victim had struggled to breathe that morning before dying, and the death certificate listed “pneumonia” as the cause of death, even after a positive test for COVID-19, one of those people said. The people interviewed did not want to be identified for fear of retribution.

Three employees of shops in the complex that houses the funeral home said there had been a marked increase in the number of people going there in recent days. One estimated about 150 bodies were being cremated daily, up from what is normally a few dozen a day.

One employee attributed it to the coronavirus, although another said there are usually more deaths with the arrival of winter. The employees did not want to be identified for fear of retribution. 

China has not reported a death from COVID-19 since Dec. 4.

China’s official death toll remains low, with just 5,235 deaths — compared with 1.1 million in the United States. However, public health experts caution that such statistics can’t be directly compared.

Chinese health authorities count only those who died directly from COVID-19, excluding those whose underlying conditions were worsened by the virus. In many other countries, guidelines stipulate that any death where the coronavirus is a factor or contributor is counted as a COVID-19-related death.

Experts say this has been the long-standing practice in China, but questions have been raised at times about whether officials have sought to minimize the figures.

Also on Friday, China’s Cabinet ordered rural areas to prepare for the return of migrant workers this holiday season in hopes of preventing a big surge in COVID-19 cases in communities with limited medical resources.

Returnees must wear masks and avoid contact with elderly people, and village committees must monitor their movements, the guidelines said, but didn’t mention the possibility of isolation or quarantines.

There are fears of a surge in cases around China’s winter holidays, when tens of millions take to trains, buses and planes for what may be their only trip home all year. 

The upcoming Lunar New Year falls on Jan. 22, but migrants generally begin heading home two weeks or more in advance. Some Chinese universities say they will allow students to finish the semester from home to help spread out the travel rush and reduce the potential for a bigger outbreak.

Medical resources in smaller cities and rural communities, which are home to about 500 million of China’s 1.4 billion people, lag far behind those of large cities such as Beijing and Shanghai. Rural medical infrastructure includes 17,000 county-level hospitals — many of which lack even a single ICU bed — 35,000 township health centers and 599,000 village clinics.

China has been pushing to increase the number of fever clinics in rural areas to treat those with COVID-19 symptoms. Currently, about 19,400 such clinics or consulting rooms operate in communities and townships around the country, state media reported Friday.

By March 2023, about 90% of health centers at the township level will have fever clinics, Nie Chunlei, head of primary health at the National Health Commission, said Thursday.

“This will effectively enhance the capability of primary-level health care institutions to receive patients with fever,” said Nie, who also urged stockpiling of medicines and antigen test kits, many of which have become scarce even in big cities.

The lifting of some travel regulations has spurred both relief and anxiety over the level of COVID-19 preparedness.

Health experts have said China will face a peak of infections in the next month or two and is trying to persuade reluctant seniors and others at risk to get vaccinated.

The changes follow growing frustration with the “zero-COVID” policy blamed for hindering the economy and creating massive social stress. The easing began in November and accelerated after Beijing and several other cities saw protests over the restrictions that grew into calls for President Xi Jinping and the Communist Party to step down — a level of public dissent not seen in decades.

It’s unclear what prompted the government’s shift in policy. Experts cite economic pressure, public discontent, and the difficulties of containing the extremely infectious omicron variant as factors.

China wasn’t fully prepared for opening up from a public health standpoint, and the decision was driven mainly by economic and social factors, said Zeng Guang, a health expert formerly affiliated with China’s Center for Disease Control, speaking at a conference organized by the state-run Global Times newspaper.

Under the relaxed rules, obligatory testing is no longer required and people with mild symptoms are permitted to recover at home rather than go to a quarantine center. Meanwhile, the semi-autonomous gambling enclave of Macao will scrap its mandatory hotel quarantine for arrivals from Hong Kong, Taiwan and overseas starting Saturday, the government said.

However, travelers must spend five days in home isolation and undergo testing and are barred from entering mainland China until the 10th day upon arrival. Both Macao and Hong Kong have scrapped most anti-COVID-19 measures.

he World Health Organization warns billions of people who lack access to safe drinking water, sanitation and hygiene are at risk of deadly infectious diseases. The finding appears in the WHO and U.N.-Water’s Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS) report issued this week.

Data collected from 121 countries show billions of people are facing a health crisis and states must act urgently to improve water, sanitation and hygiene, known as WASH. The report, the most comprehensive to date, finds most countries are not on track to achieve the U.N. sustainable development goal of providing water and sanitation for all by 2030.

Bruce Gordon is unit head, water, sanitation, hygiene and health at the WHO. While dramatic acceleration is needed, he says only 25 percent of countries are on track to meet their target for sanitation and only 45 percent for drinking water.

((GORDON ACT))

“This is against the backdrop of a tremendous amount of disease from diarrhea linked to ingestion of poor water, the root cause of poor sanitation. Lack of hand hygiene that impacts also on respiratory infections. And so, almost 2 million people are dying every year because of poorly managed water, sanitation and hygiene.”

((END ACT))

Gordon says countries need to recommit to the targets they have made to save those lives. He notes a major opportunity to do that will occur during an historic U.N. water and sanitation conference in March. For the first time in 50 years, he says, the global community will gather to review progress and make voluntary commitments to improve the water situation.

The report delves into the impact climate-related extreme weather events have on impeding the delivery of safe WASH services. Gordon says the report highlights the importance of climate resilience and adaptation to climate change.

((2ND GORDON ACT))

“And yet when we look at the policy response, whether it is climate resilient technologies which—there are simple things to avoid floods or to mitigate droughts. Simple risk management or simple technologies. These are not being put in place.”

((END ACT))

The WHO report calls on governments to dramatically increase investments to extend access to safely managed drinking water and sanitation services. It urges them to scale up support for WASH service delivery by putting in place monitoring systems, regulatory functions and capacity development.

The World Health Organization says climate change is behind an unprecedented surge in the number of cholera outbreaks around the world this year.

At least 30 countries have reported outbreaks of the deadly disease this year, about a third higher than normally seen.

Philippe Barboza, WHO’s team leader for cholera and epidemic diarrheal diseases, said most of the large cholera outbreaks have coincided with adverse climate events and have been visibly and directly affected by them.

“Very severe droughts like, for example, in the Horn of Africa, in the Sahel but also in other parts of the world,” he said. “Major floods, unprecedented monsoons, succession of cyclones. So, most again, most of these outbreaks appear to be fueled by the result of the climate change.”

No quick reprieve is in sight. The World Meteorological Organization predicts the so-called La Nina climate phenomenon will last through the end of this year. The pattern, which cools the surface of ocean waters, is expected to continue well into 2023. That will result in prolonged droughts and flooding and increased cyclones.

Consequently, health officials warn large cholera outbreaks are likely to continue and spread to wider areas over the next six months. Barboza said preventing disease outbreaks will be a challenge.

He said a global shortage of vaccine has forced the WHO to temporarily suspend its two-dose strategy and switch to a single dose approach. That allows many more people to be vaccinated against cholera. However, he said it shortens the period of immunity against infection.

“So, the situation will continue to prevail for the months to come,” he said. “There is no silver bullet, magic solution and the producers are at the maximum production. … So, there is no hope that the situation will improve in the coming weeks or months.”

Barboza said lack of data makes it impossible to accurately determine the number of global cholera cases and deaths. However, he noted information from at least 14 countries indicates the average fatality rate is above 1%. He said the cholera fatality rate in heavily affected Haiti is around 2%.

Cholera is an acute diarrheal disease caused by consuming contaminated food or water. Treatments include oral rehydration. People with severe cases need rapid intravenous fluids and antibiotics. Cholera can kill within hours if left untreated.

Russian and NASA engineers were assessing a coolant leak on Thursday from a Soyuz crew capsule docked with the International Space Station that could have been caused by a micrometeorite strike.

Dramatic NASA TV images showed white particles resembling snowflakes streaming out of the rear of the vessel for hours.

The coolant leak forced the last-minute cancellation of a spacewalk by two Russian cosmonauts on Wednesday and could potentially impact a return flight to Earth by three crew members.

Leak posed no danger

Russia’s space corporation Roscosmos and the U.S. space agency said the leak on the Soyuz MS-22 spacecraft did not pose any danger to the astronauts and cosmonauts aboard the space station.

“The crew members aboard the space station are safe, and were not in any danger during the leak,” NASA said.

It said ground teams were evaluating “potential impacts to the integrity of the Soyuz spacecraft.”

“NASA and Roscosmos will continue to work together to determine the next course of action,” NASA said.

The TASS news agency quoted Sergei Krikalev, a former cosmonaut who heads the crewed space flight program for Roscosmos, as saying that the leak could have been caused by a tiny meteorite striking Soyuz MS-22.

“The cause of the leak may be a micrometeorite entering the radiator,” TASS quoted Krikalev as saying. “Possible consequences are changes in the temperature regime.”

“No other changes in the telemetric parameters of either the Soyuz spacecraft or the (ISS) station on the Russian or American segments have been detected,” Krikalev said.

NASA later added that the crew on the station “completed normal operations Thursday, including … configuring tools ahead of a planned US spacewalk on Monday.”

Soyuz MS-22 flew Russian cosmonauts Sergei Prokopyev and Dmitry Petelin and NASA astronaut Frank Rubio to the space station in September.

It is scheduled to bring them back to Earth in March and another vessel would have to be sent to the space station if Soyuz MS-22 is unavailable.

Prokopyev and Petelin had been making preparations for a spacewalk on Wednesday when the leak was discovered.

“The crew reported the warning device of the ship’s diagnostic system went off, indicating a pressure drop in the cooling system,” Roscosmos said. “At the moment, all systems of the ISS and the ship are operating normally, the crew is safe.”

NASA said the leak had occurred on the “aft end” of Soyuz MS-22, which is secured to the space station.

International collaboration

There are currently four other astronauts and cosmonauts aboard the space station in addition to Rubio, Prokopyev and Petelin.

NASA astronauts Josh Cassada and Nicole Mann, Japanese astronaut Koichi Wakata and Russian cosmonaut Anna Kikina were flown to the space station in October aboard a SpaceX spacecraft.

Space has been a rare avenue of cooperation between Moscow and Washington since the start of Moscow’s assault on Ukraine in February, and ensuing Western sanctions on Russia that shredded ties between the two countries.

The ISS was launched in 1998 at a time of increased US-Russia cooperation following their Space Race competition during the Cold War.

The United States is monitoring for new coronavirus variants as it braces for a potential outbreak of COVID-19 infections following Beijing’s easing of strict controls that kept the pandemic at bay in China.

“We have a very robust surveillance program that we use for travelers as people come in, in terms of identifying people who are infected, tracking variants,” Ashish Jha, White House coronavirus response coordinator, told VOA during a briefing with reporters on Thursday. “And if there are new variants that emerge, I’m confident that we will be able to identify them.”

Jha said the monitoring mechanism includes testing wastewater in the U.S. and through partners abroad.

China changes its approach

On Wednesday, Beijing announced major changes to its national pandemic response, moving away from its strict zero-COVID approach, which relied heavily on lockdowns and prompted protests across the country. The new guidelines no longer mandate health QR codes to enter public places and allow patients with mild cases to quarantine at home instead of in crowded government facilities.

A major COVID-19 outbreak in China would have unpredictable effects on the virus, said Xi Chen, Yale University professor of public health.

“The world’s most populous country includes a large number of immunocompromised people who can harbor the virus for months,” he told VOA. 

Those conditions, he said, “may produce variants of concern.”

However, Chen noted there may be a reduced risk of new variants spinning out of a Chinese outbreak.

“China has stuck with zero-COVID so long that its population has, by and large, never encountered omicron subvariants; people’s immune systems remain trained almost exclusively on the original version of the coronavirus, raising only defenses that currently circulating strains can easily get around,” he said. “It’s possible that there will be less pressure for the virus to evolve to evade immunity further.”

The World Health Organization has raised concerns that China’s 1.4 billion citizens are not adequately vaccinated, particularly its elderly and vulnerable populations.

Beijing has ramped up its immunization efforts, on average more than 1 million shots each day. But with holiday travel coming and the time needed to build up immunity after vaccinations, the window is narrowing, Chen said.

“Perhaps the coming two weeks will be the last opportunity to avoid accelerated virus transmissions throughout China.”

As it braced for new infections, China began selling Paxlovid, an oral COVID-19 treatment made by American company Pfizer this week.

Jha said that the deal was reached without the administration’s involvement but said that the U.S. offered to help China with vaccinations stands.

“We have been the largest donor of vaccines in the world, almost 700 million doses,” he said. “We stand ready to help any country that needs help.”

Winter preparedness plan

On Thursday, the White House issued what it is calling its COVID-⁠19 Winter Preparedness Plan.

“We don’t want this winter to look like last winter or the winter before,” Jha said.

In a statement, the White House said that while COVID-19 “is not the disruptive force it once was, the virus continues to evolve,” and the latest data from the U.S. Centers for Disease Control and Prevention shows new cases, hospitalizations and deaths are all up in recent days.

The White House said in addition to free testing sites that already exist, beginning Thursday, all U.S. households can order a total of four at-home COVID-19 tests that will be mailed directly to them free. Free at-home tests also will be made available at government-assisted rental housing properties serving seniors and food banks.

The administration also is outlining to all governors the actions they should take to prepare for increased cases and hospitalizations expected during the winter.

China raced to vaccinate its most vulnerable people on Thursday in anticipation of waves of COVID-19 infections, with some analysts expecting the death toll to soar after it eased strict controls that had kept the pandemic at bay for three years. 

The push comes as the World Health Organization also raised concerns that China’s 1.4 billion population was not adequately vaccinated and the United States offered help in dealing with a surge in infections.

Beijing last Wednesday began dismantling its tough ‘zero-COVID’ controls, dropping testing requirements and easing quarantine rules that had caused mental stress for tens of millions and battered the world’s second largest economy.

The pivot away from President Xi Jinping’s signature “zero-COVID” policy followed unprecedented widespread protests against it. But, WHO emergencies director Mike Ryan said infections were exploding in China well before the government’s decision to phase out its stringent regime. 

“There’s a narrative at the moment that China lifted the restrictions and all of a sudden the disease is out of control,” Ryan told a briefing in Geneva.

“The disease was spreading intensively because I believe the control measures in themselves were not stopping the disease.”

Chinese foreign ministry spokesperson Wang Wenbin said on Thursday China has “institutional advantages” to fight COVID.

“We will certainly be able to smoothly get through the peak of the epidemic,” he told a regular news briefing in response to White House national security spokesperson John Kirby saying that the U.S. was ready to help if China requested it.

There are increasing signs of chaos during China’s change of tack – with long queues outside fever clinics, runs on medicines and panic buying across the country.

One video posted online on Wednesday showed several people in thick winter clothes hooked up to intravenous drips as they sat on stools on the street outside a clinic in central Hubei province. Reuters verified the location of the video.

The COVID scare in China also led people in Hong Kong, Macau and in some neighborhoods in Australia to go in search for fever medicines and test kits for family and friends on the mainland.

For all its efforts to quell the virus since it erupted in the central city of Wuhan in late 2019, China may now pay a price for shielding a population that lacks “herd immunity” and has low vaccination rates among the elderly, analysts said.

“Authorities have let cases in Beijing and other cities spread to the point where resuming restrictions, testing and tracing would be largely ineffective in bringing outbreaks under control,” analysts at Eurasia Group said in a note on Thursday.

“Upward of 1 million people could die from COVID in the coming months.”

Other experts have put the potential toll at more than 2 million. China has reported just 5,235 COVID-related deaths so far, extremely low by global standards.

China’s stock markets and its currency fell on Thursday on concerns of the virus spread.

China reported 2,000 new symptomatic COVID-19 infections for Dec. 14 compared with 2,291 a day. The official figures, however, have become less reliable as testing has dropped. It also stopped reporting asymptomatic figures on Wednesday.

Concern for elderly 

China, which has said around 90% of its population is vaccinated against COVID, has now decided to roll out the second booster shot for high-risk groups and elderly people over 60 years of age. 

National Health Commission spokesperson Mi Feng said on Wednesday it was necessary to accelerate the promotion of vaccinations, according to comments reported by state media.

The latest official data shows China administered 1.43 million COVID shots on Tuesday, well above rates in November of around 100,000-200,000 doses a day. In total, it has administered 3.45 billion shots.

But one Shanghai care home said on Wednesday a number of its residents have not yet been vaccinated and considering their underlying medical condition, it has barred visitors and non-essential deliveries while stockpiling medicines, tests kits and protective gear.

“We are racking our brains on how to ensure the safety of your grandparents,” the Yuepu Tianyi Nursing Home wrote in a letter posted on its official WeChat account page.

Beijing has been largely resistant to western vaccines and treatments, having relied on locally-made shots. Pfizer’s oral COVID-19 treatment Paxlovid is one of the few foreign ones it has approved.

The treatment, however, has only been available in hospitals for high-risk patients, but signs have appeared in recent days that it may soon be made more widely available.

China Meheco Group Co Ltd’s stock jumped after it announced a deal to import the U.S. drugmaker’s treatment on Wednesday.

Economic conference

As the virus spreads, President Xi, his ruling Politburo and senior government officials began a two-day meeting to plot a recovery for China’s battered economy, according to sources with knowledge of the matter.

China’s economy lost more steam in November as factory output growth slowed and retail sales extended declines, both missing forecasts and clocking their worst readings since May, data on Thursday showed.

Economists estimate that China’s growth has slowed to around 3% this year, marking one of China’s worst performances in almost half a century. 
…

A week after China dramatically eased its three-year-long zero-COVID policy of lockdowns and near-daily PCR testing, the country is experiencing its biggest wave of COVID-19 infections since the pandemic began in 2020.

But Ray Yip, an American epidemiologist and a former director of the China branch of the U.S. Centers for Disease Control and Prevention, and Professor Jin Dong-Yan, a virologist in the University of Hong Kong’s Department of Biochemistry, say the relatively mild nature of omicron, China’s high vaccination rate and people voluntarily staying home, could help China avoid a huge increase in deaths.

Yip, who is also a former head of the China office for UNICEF and the Bill & Melinda Gates Foundation, and Jin, a respected virologist, explained to VOA’s Cindy Sui why the situation in China may not be as bad as feared.

These December 14 and 15 interviews have been edited for length and clarity.

VOA: What is going on in China’s hospitals?

Yip: Most hospitals in big cities right now are overrun, but they are overrun from basically people with symptoms that don’t have to go to the hospital, like fever and runny nose. The truth is, COVID is like any flu. Unless you’ve developed respiratory failure and you need to have higher-level care, you get better on your own. You just drink a lot of fluid and stay in bed. But in China, most people, most parents, believe every time your child or your family member has anything not well, you rush them to the hospital emergency room to get [an] IV. Half the people don’t know you can use something like ibuprofen, acetaminophen, and manage the fever yourself.  

So right now, is there an omicron outbreak in Beijing, in Shanghai, in every place? The answer is yes. But that doesn’t mean hospitals’ intensive care is overrun and the number of deaths of the elderly is shooting through the roof.

Jin: Most of the cases are mild. Some of them describe it as worse than the flu. That’s actually not very surprising because it’s just like the flu.

VOA: Could there be a lot of severe cases that we just don’t know about?

Jin: That’s not possible because the virus is very mild and the vaccination rate in the elderly is not very, very low. (According to government statistics, 86% of the elderly aged 60 or above have had two shots and 68% have had a third booster shot). It’s much higher than in February in Hong Kong (when a major outbreak occurred).

The rate of severe cases or deaths should not be that high … because 99.5% of the people will just have mild or no symptoms for omicron. It’s the same everywhere. As long as they do well in vaccinating the elderly and giving them oral antivirals, the number of severe cases and deaths can be avoided.

VOA: With so many new infections, is there a possibility that the same thing that happened in India will happen in China as omicron spreads, given that there are only 3.6 intensive care beds per 100,000 people in China?

Yip: I don’t think that will happen in China. Omicron doesn’t do that. Omicron causes symptoms of cold. It doesn’t cause pneumonia. It doesn’t make you have trouble breathing. It’s upper respiratory.

Jin: That’s completely different because it’s not the same virus and strain. That will not happen in Beijing. For most people, there won’t be need for respirators because it’s the same viral strain as in Inner Mongolia, and as you can see there are not that many deaths and severe cases there. The concept that the virus strain is particularly virulent and will kill a lot of people is wrong.

VOA: According to the government, 90% of the population has been vaccinated with two doses of Chinese vaccines, but a much lower percentage — 56% of the overall population, and just 40% of those 80 or older — have had a booster shot. Would there still be an increase in deaths among the most vulnerable people?

Yip: All those people having COVID now, they are not very old. So, the question is, will this become so pervasive, so rapid, that it will actually overwhelm the elderly population in a very short period of time? If that happens, then there are fears that what happened in Wuhan in the first few weeks in January 2020 will happen again, with bodies lying in the hallways, not enough hospital beds and respirators.

I really doubt these scenes will repeat themselves. My prediction is that even if China gets a very sharp curve, the outcome — in terms of overwhelming the hospitals and deaths — will not be as bad as what happened in Wuhan in 2020 because it’s a different virus. Omicron, even though it’s COVID, is much milder.

There will be 200,000 excess deaths, mostly elderly people. But if you spread that out over a huge country like China, that’s not huge.

Jin: There’s always a danger, but every country has to face that. It’s just that China is facing it all of a sudden. Sooner or later, there would be a tsunami, it’s not a big deal, but they do need to pay more attention to severe cases.  In reality, how they can deal with severe cases and identify them is difficult. If they can quickly deliver oral antiviral drugs to those who need it, or those with chronic underlying diseases, it will also save a lot of lives.

VOA: What can China do to avoid a large number of deaths?

Yip: They can minimize deaths by getting the elderly vaccinated and making sure everybody gets three shots. They can also soften the curve, by keeping the rise in cases spread out over a longer period of time. A sharp curve will result in many people getting very sick that might overwhelm the hospitals. But if there’s a gentle curve that goes up over a longer period of time, then the hospitals will be able to handle the caseloads.

With China’s curve, we just have to see. But my prediction is it may not be as bad as one assumes, and the reason for that is that most Chinese in the big cities are totally scared. Beijing right now is in a semi-imposed semi-lockdown. You can go anywhere you want, but people are not going, because everybody right now hears COVID is running amok. So, everybody is staying in their apartment, which is good. By doing that, they will actually make the curve more gentle, not as steep.

Jin: Actually, the most important thing is to educate the general public and explain the rationale of the new policy. They should tell people they don’t need to go to the hospitals, because if everyone infected goes to the hospitals, the hospitals will collapse at some point.

In terms of the curve, they want to have 60% of people infected in the first wave. That’s not possible if everyone stays home, because the virus will not spread anymore. It’s possible it’ll be like Taiwan and Singapore, they will see several waves. They hope to have 80% of the population infected in the second wave.

VOA: Is there a chance China might ride out this storm largely unscathed?

Yip: There’s a reasonable chance China actually might, if what I’m hoping or projecting comes true. As we mentioned earlier, a flatter curve allows the system to absorb the shock. We don’t know. I think you need to wait for another minimum of three weeks to tell. Omicron actually is the best thing that happened to the world. Without omicron, if the virus was still like the delta variant, the alpha, the Wuhan strain, you would be scared every place you go. Omicron immunized everybody. The whole continent of Africa was immunized by omicron.

Jin: We expect the severe cases will be low and they should be able to handle this.  If they cannot handle it, they should use other measures to flatten the curve. There are 101 measures to do this. They can close schools, shut down buses, metro systems, they can do everything.

VOA: So, if China also survives this omicron wave, would you agree with Chinese analysts’ assertions that China will have prevented millions of deaths with its zero-COVID policy, even though it has been blamed for hurting the economy and people’s livelihoods, while also restricting  freedom?

Jin: I think so because that’s the reality, because the most lethal waves are already over. Those are delta, alpha … They have saved millions of lives because they did the lockdown initially and it could have been much worse if they didn’t.

Yip: That is true. I’ll tell you why. China did this zero-COVID policy when the bad virus was around — the virus that killed a lot of people, the one you saw in India, in New York, in Italy, in many parts of the world. It killed a million Americans. Those were the older strains. So, China basically said, ‘I protect you during bad virus times, but we got a good virus now. I’m going to let you get infected. You will get sick. You will get a cold. But most of you, if you’re under 50, you have zero chance to die. If you’re over 60 and you’re immunized, you’re in good condition.’

So basically, China averted a major curve of COVID-related deaths. But I tell you, people in the West don’t like to hear that because it makes China look good. You should report it. What I’m telling you is based on epidemiology. It’s based on science. I’m not telling you based on politics.

National Health Service nurses in Britain will strike on Thursday in their first-ever national walkout as a bitter dispute with the government over pay ramps up pressure on already-stretched hospitals at one of the busiest times of year.

An estimated 100,000 nurses will strike at 76 hospitals and health centers on Thursday, canceling thousands of non-urgent operations, such as hip replacements, and tens of thousands of outpatient appointments in Britain’s state-funded NHS.

Britain is facing a wave of industrial action this winter, with strikes crippling the rail network and postal service, and airports bracing for disruption over Christmas.

Inflation running at more than 10%, trailed by pay offers of around 4%, is stoking tensions between unions and employers.

Of all the strikes though, it will be the sight of nurses on picket lines that will be the standout image for many Britains this winter.

“It is deeply regrettable some union members are going ahead with strike action,” health minister Steve Barclay said.

“I’ve been working across government and with medics outside the public sector to ensure safe staffing levels — but I do remain concerned about the risk that strikes pose to patients.”

Considered a national treasure

The widely admired nursing profession will shut down parts of the NHS, which since its founding in 1948 has developed national treasure status for being free at the point of use, hitting health care provision when it is already stretched in winter and with backlogs at record levels due to COVID delays

Barclay said patients should continue to seek urgent medical care and attend appointments unless they have been told not to.

The industrial action by nurses on Thursday and December 20 is unprecedented in the British nursing union’s 106-year history, but the Royal College of Nursing (RCN) said it has no choice as workers struggle to make ends meet.

Nurses want a 19% pay rise, arguing they have suffered a decade of real-terms cuts and that low pay means staff shortages and unsafe care for patients. The government has refused to discuss pay.

The government in Scotland avoided a nursing strike by holding talks on pay, an outcome that the RCN had hoped for in England, Wales and Northern Ireland, but Barclay is not budging.

The government has said it cannot afford to pay more than the 4-5% offered to nurses, which was recommended by an independent body, and that further pay increases would mean taking money away from frontline services.

The RCN has accused the government of “belligerence.” It said as late as Tuesday that the strikes could still be stopped if the government was prepared to negotiate.

Some treatments exempt from strike

Some treatment areas will be exempt from strike action the RCN has said, including chemotherapy, dialysis and intensive care.

Polling ahead of the nursing strike showed that a majority of Britains support the action, but once the walkouts are underway, politicians will be closely monitoring public opinion.

What’s a dust devil sound like on Mars? A NASA rover by chance had its microphone on when a whirling tower of red dust passed directly overhead, recording the racket.

It’s about 10 seconds of not only rumbling gusts of up to 25 mph (40 kph), but the pinging of hundreds of dust particles against the rover Perseverance. Scientists released the first-of-its-kind audio Tuesday.

It sounds strikingly similar to dust devils on Earth, although quieter since Mars’ thin atmosphere makes for more muted sounds and less forceful wind, according to the researchers.

The dust devil came and went over Perseverance quickly last year, thus the short length of the audio, said the University of Toulouse’s Naomi Murdoch, lead author of the study appearing in Nature Communications. At the same time, the navigation camera on the parked rover captured images, while its weather-monitoring instrument collected data.

“It was fully caught red-handed by Persy,” said co-author German Martinez of the Lunar and Planetary Institute in Houston.

A 1-in-200 chance

Photographed for decades at Mars but never heard until now, dust devils are common at the red planet. This one was in the average range: at least 400 feet (118 meters) tall and 80 feet (25 meters) across, traveling at 16 feet (5 meters) per second.

The microphone picked up 308 dust pings as the dust devil whipped by, said Murdoch, who helped build it.

Given that the rover’s SuperCam microphone is turned on for less than three minutes every few days, Murdoch said it was “definitely luck” that the dust devil appeared when it did on Sept. 27, 2021. She estimates there was just a 1-in-200 chance of capturing dust-devil audio.

Of the 84 minutes collected in its first year, there’s “only one dust devil recording,” she wrote in an email from France.

A helicopter named ‘Ingenuity’

This same microphone on Perseverance’s mast provided the first sounds from Mars — namely the Martian wind — soon after the rover landed in February 2021. It followed up with audio of the rover driving around and its companion helicopter, little Ingenuity, flying nearby, as well as the crackle of the rover’s rock-zapping lasers, the main reason for the microphone.

These recordings allow scientists to study the Martian wind, atmospheric turbulence and now dust movement as never before, Murdoch said. The results “demonstrate just how valuable acoustic data can be in space exploration.”

On the prowl for rocks that might contain signs of ancient microbial life, Perseverance has collected 18 samples so far at Jezero Crater, once the scene of a river delta. NASA plans to return these samples to Earth a decade from now. Ingenuity has logged 36 flights, the longest lasting almost three minutes.

A South African researcher has developed a way to remove contaminants from water used in mining that could help clean up the dirty industry. The award-winning ion exchange method not only cleans the water but captures polluting metals that can then be re-purposed.

At a Johannesburg laboratory, researchers from the University of the Witwatersrand have developed a way to clean acid mine drainage (AMD).

AMD is the runoff of pollutants like sulfuric acid and heavy metals that secrete into waterways, affecting wildlife and rural mining communities.

AMD is often found at gold and coal mines, which are plentiful in South Africa.

Tamlyn Naidu is a post-doctoral research fellow involved in the project.

“What we wanted to do is minimize environmental impact for a lot of these communities that are afflicted by AMD. They have been born into mining communities, they work in mining communities, they’re either scared to report it or to complain about it, because this is their livelihood,” she said.

The ion exchange filtration system that Naidu and her colleagues have developed uses countless polystyrene beads, each the size of a pinhead, which the water passes through.

Unlike a coffee filter, which physically blocks coffee grounds from passing through with water, the beads grab the contaminants in the water chemically.

The passing water, which can be scaled up to clean 1,000 liters an hour, then comes out clear.

“This project though, does something extra. It also wants to extract from the water valuable materials. So what has been identified in some of these streams, especially coal mining streams, is that the acid that’s produced from the mine waters actually dissolves out some rare earth metals,” says Ed Hardwick, the owner of Cwenga Technologies, which is a partner in the research.

Rare earth metals are in huge demand globally because they can be used in new technology like electric vehicles. Being able to extract them adds a financial incentive to cleaning up AMD.

Naidu said she hopes this can empower communities by monetizing the extracted materials from the AMD.

“Ultimately, from this project, we want community members to be involved in something that’s easy for them to operate, that they can extract value from and start, you know, seeing the value that companies have been taking onto the land and taken away from them. And yeah, I guess adding to their quality of life,” she says.

A method to clean up AMD that can be monetized would be good news for the government and communities that are now burdened with the costly task.

“If this was going to be an incentive, it should be on the incentive of the state and that any monies that are obtained from the separation of those minerals that can be repurposed, that can be used, is then fed back into one rehabilitation, but also two, into creating sustainable economies for the communities that are impacted,” says Tarisai Mugunyani, an attorney with the Center for Environmental Rights in Johannesburg.

Researchers say they are hopeful their filtration system, which can be adapted to clean the unique chemistry of AMD at any site, will soon be adopted widely.

It has already gained international attention with Naidu taking the first prize for emerging talents breakthroughs at the Falling Walls Science Summit in Berlin last month.

Naidu said several companies in mining and technology sectors have contacted her about becoming involved.

New Zealand on Tuesday passed into law a unique plan to phase out tobacco smoking by imposing a lifetime ban on young people buying cigarettes.

The law states that tobacco can’t ever be sold to anybody born on or after January 1, 2009.

It means the minimum age for buying cigarettes will keep going up and up. In theory, somebody trying to buy a pack of cigarettes 50 years from now would need ID to show they were at least 63 years old.

But health authorities hope smoking will fade away well before then. They have a stated goal of making New Zealand smoke-free by 2025.

The new law also reduces the number of retailers allowed to sell tobacco from about 6,000 to 600 and decreases the amount of nicotine allowed in tobacco that is smoked.

“There is no good reason to allow a product to be sold that kills half the people that use it,” Associate Minister of Health Dr. Ayesha Verrall told lawmakers in Parliament. “And I can tell you that we will end this in the future, as we pass this legislation.”

She said the health system would save billions of dollars from not needing to treat illnesses caused by smoking, such as cancer, heart attacks, strokes, and amputations. She said the bill would create generational change and leave a legacy of better health for youth.

Lawmakers voted along party lines in passing the legislation 76 to 43.

The libertarian ACT party, which opposed the bill, said many small corner stores, known in New Zealand as dairies, would go out of business because they would no longer be able to sell cigarettes.

“We stand opposed to this bill because it’s a bad bill and its bad policy, it’s that straightforward and simple,” said Brooke van Velden, ACT’s deputy leader. “There won’t be better outcomes for New Zealanders.”

She said the gradual ban amounted to “nanny-state prohibition” that would end up creating a large black market. She said prohibition never worked and always ended with unintended consequences.

The law does not affect vaping, which has already become more popular than smoking in New Zealand.

Statistics New Zealand reported last month that 8% of New Zealand adults smoked daily, down from 16% ten years ago. Meanwhile, 8.3% of adults vaped daily, up from less than 1% six years ago.

Smoking rates remain higher among Indigenous Māori, with about 20% reporting they smoked.

New Zealand already restricts cigarette sales to those aged 18 and over, requires tobacco packs to come with graphic health warnings and cigarettes to be sold in standardized packs.

New Zealand in recent years also imposed a series of hefty tax hikes on cigarettes.

The law change was welcomed by several health agencies. Health Coalition Aotearoa said the new law represented the culmination of decades of hard-fought advocacy by health and community organizations.

The Department of Energy planned an announcement Tuesday on a “major scientific breakthrough” at the Lawrence Livermore National Laboratory, one of several sites worldwide where researchers have been trying to develop the possibility of harnessing energy from nuclear fusion. 

It’s a technology that has the potential to one day accelerate the planet’s shift away from fossil fuels, which are the major contributors to climate change. The technology has long struggled with daunting challenges. 

Here’s a look at exactly what nuclear fusion is, and some of the difficulties in turning it into the cheap and carbon-free energy source that scientists believe it can be. 

What is nuclear fusion? 

Look up, and it’s happening right above you — nuclear fusion reactions power the sun and other stars. 

The reaction happens when two light nuclei merge to form a single heavier nucleus. Because the total mass of that single nucleus is less than the mass of the two original nuclei, the leftover mass is energy that is released in the process, according to the Department of Energy. 

In the case of the sun, its intense heat — millions of degrees Celsius — and the pressure exerted by its gravity allow atoms that would otherwise repel each other to fuse. 

Scientists have long understood how nuclear fusion has worked and have been trying to duplicate the process on Earth as far back as the 1930s. Current efforts focus on fusing a pair of hydrogen isotopes — deuterium and tritium — according to the Department of Energy, which says that particular combination releases “much more energy than most fusion reactions” and requires less heat to do so. 

How valuable would this be?

Daniel Kammen, a professor of energy and society at the University of California at Berkeley, said nuclear fusion offers the possibility of “basically unlimited” fuel if the technology can be made commercially viable. The elements needed are available in seawater. 

It’s also a process that doesn’t produce the radioactive waste of nuclear fission, Kammen said. 

How are scientists trying to do this? 

One way scientists have tried to recreate nuclear fusion involves what’s called a tokamak — a doughnut-shaped vacuum chamber that uses powerful magnets to turn fuel into a superheated plasma (between 150 million and 300 million degrees Celsius) where fusion may occur. 

The Livermore lab uses a different technique, with researchers firing a 192-beam laser at a small capsule filled with deuterium-tritium fuel. The lab reported that an August 2021 test produced 1.35 megajoules of fusion energy — about 70% of the energy fired at the target. The lab said several subsequent experiments showed declining results, but researchers believed they had identified ways to improve the quality of the fuel capsule and the lasers’ symmetry. 

“The most critical feature of moving fusion from theory to commercial reality is getting more energy out than in,” Kammen said.

A Franco-U.S. satellite is due for launch this week on a mission to survey with unprecedented accuracy nearly all water on Earth’s surface for the first time and help scientists investigate its impact on Earth’s climate.

For NASA and France’s space agency CNES, which have worked together in the field for 30 years, it’s a landmark scientific mission with a billion-dollar budget.

French President Emmanuel Macron went to NASA’s Washington headquarters at the end of November alongside U.S. Vice President Kamala Harris.

He highlighted the liftoff — scheduled for early Thursday on the U.S. West Coast — of the Surface Water and Ocean Topography (SWOT) mission to monitor the levels of oceans, lakes and rivers, including in remote locations.

Its predecessor, TOPEX/Poseidon, launched in 1992, was also a Franco-U.S. joint venture that measured ocean surface to an accuracy of 4.2 centimeters (1.7 inches).

It aided the forecast of the 1997-1998 El Nino weather phenomenon and improved understanding of ocean circulation and its effect on global climate.

The 2.2-metric ton SWOT mission will be put into orbit from Vandenberg Space Force Base in California atop a SpaceX Falcon 9 rocket.

The satellite’s primary payload is an innovative instrument to measure the height of water called KaRin, or Ka-band radar interferometer. Its two antennas, separated by a big boom, create parallel swaths of data.

“We’re going to get 10 times better resolution than with current technologies to measure sea-surface height and understand the ocean fronts and eddies that help shape climate,” said NASA Earth Science Division Director Karen St. Germain.

“It’s like looking at a car number plate from space when before we could only see a street,” added Thierry Lafon, SWOT project leader at the CNES.

The stakes are high. While the impact of major ocean currents such as the Gulf Stream is known, more local flows and eddies covering dozens of kilometers remain more of a mystery.

But they too affect sea water surface temperatures and heat transfer as well as the absorption by the oceans of carbon dioxide from the atmosphere.

SWOT will improve weather and climate modeling, the observation of coastal erosion and help track how fresh and saltwater bodies change over time.

With an “optimal” orbit of 890 kilometers (about 550 miles) above Earth, Lafon said SWOT will “take in all the components that affect water levels such as tides and the sun.”

NASA said SWOT will survey nearly all water on Earth’s surface for the first time.

It will monitor water levels, surface areas and quantities at more than 20 million lakes with shores of more than 250 meters. The entire length of rivers more than 100 meters wide will also be observed.

Water management, flood and drought prevention will be improved, said Lafon.

Flying the satellite to Vandenberg from the Thales Alenia Space (TAS) site in Cannes, southern France, proved a headache.

“Due to the conflict in Ukraine, there were no more Antonov 124s available, and the 747 cargo is too small,” said TAS project leader Christophe Duplay. “We decided to ask the [U.S. Air Force] to provide one of its C-5 Galaxies.”

And that meant counting on NASA to have the air force supply one of its rare giant aircraft to ship the huge payload.

SWOT has an estimated three-year lifetime — although Lafon said “nothing precludes the mission to last five to eight years” — and is set to become the first satellite to make a controlled reentry into Earth’s atmosphere, reducing the amount of space debris, in line with the French space operations act.

Nearly 80% of the 400 kilos (880 pounds) of onboard fuel will be used to that end.

The United States Department of Energy on Tuesday is expected to announce that its scientists have been able to engineer a nuclear fusion reaction that produced more energy than it consumed, a landmark achievement in a decadeslong search for a way to generate clean and waste-free nuclear power.

The pending announcement, first reported by the Financial Times and subsequently confirmed by other media organizations, will identify the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory in California as the site of the experiment.

On Monday, the department announced that Energy Secretary Jennifer Granholm would announce “a major scientific breakthrough” at a news conference Tuesday.

The announcement comes at a time when the Biden administration has directed renewed effort and funding to the development of clean power generation, with a particular emphasis on fusion energy. The recently passed Inflation Reduction Act contained significant funding for research in the field.

Just because scientists have been able to engineer an energy-positive fusion reaction does not mean that any meaningful changes to the way humans generate power are on the horizon. Experts said that while the work is important, daunting technological barriers remain in the way of systems that could deploy fusion energy at scale.

A long journey

Scientists have long known that when two atoms are fused together to form a new element, large amounts of energy are released. The sun, for example, is essentially an enormous fusion reactor in which superheated particles come together with tremendous force, forming new particles and releasing excess energy as heat.

As long ago as the 1940s, scientists began experimenting with fusion reactors. While they have long been able to generate fusion reactions, until now, those reactions have always required inputs of energy that exceeded the amount they ultimately produced.

The reason a net-positive fusion reaction has been so elusive is in large part because scientists have to generate extreme conditions in the laboratory in order to make the reactions occur. Typically, enormous lasers are used to heat isotopes of hydrogen to temperatures in the millions of degrees Celsius. The resulting plasma is then confined under extremely high pressure, causing the isotopes to come together with enough force that they fuse into a different element, releasing energy as heat when they do.

An important element of the announcement on Tuesday will be the way in which the government defines a “net positive” energy result. Typically, that means that the reaction being measured produced more energy than the laser beams directed at the hydrogen. However, the lasers used in the experiment are far from perfectly efficient, meaning that it takes more energy to power them than they ultimately bring to bear on their targets.

For a fusion reaction to be “net positive” in the sense of generating more energy than the total energy put into the experiment — including waste — the reaction would have to produce substantially more energy than that consumed by the laser beams directed at the hydrogen.

Enormous engineering challenges

Maintaining equipment that can tolerate such extreme temperatures is extraordinarily difficult, and finding a way to create reactors that can tolerate the stresses involved in the process for long periods of time is one of the many challenges facing researchers in the field.

Ian H. Hutchinson, a professor of nuclear science and engineering at Massachusetts Institute of Technology said that it was important not to read too much into preliminary reports, noting that prior to the official announcement few details of what, precisely, the scientists at the NIF have achieved was known.

“It seems an important scientific confirmation of inertial fusion ignition, but I would hesitate to call it a ‘breakthrough,’” Hutchinson said in an email exchange with VOA. “The NIF program is not aimed at fusion energy production but at understanding fusion explosions. Useful energy production from miniature fusion explosions still faces enormous engineering challenges, and we don’t know if those challenges can be overcome.”

The NIF is most closely associated with the United States’ nuclear weapons program, and its primary purpose is to recreate nuclear explosions on a small and controllable scale, allowing for the maintenance of the country’s nuclear arsenal without the need for destructive full-scale testing.

Benefits of fusion

There are several reasons why scientists have spent so many years in search of a means of making fusion reactors viable sources of energy.

If fusion reactors were to replace fossil fuels as an energy source, it would dramatically reduce the amount of carbon released into the atmosphere, reducing one source of global warming.

Unlike fission reactors, which use highly enriched radioactive materials like uranium and plutonium as fuel, fusion reactors can theoretically be fueled by hydrogen, the most abundant element in the universe, meaning that the fuel supply for a fusion reactor is essentially infinite.

Also, unlike fission reactors, fusion reactors do not produce highly radioactive waste, eliminating the need to safely store materials that will continue to be dangerous, in some cases, for thousands of years.

Finally, despite the extreme conditions under which fusion occurs, fusion reactors are considered to be safer to operate than fission reactors, which must be constantly monitored in order to avoid conditions leading to destabilization and explosion. In the two worst nuclear disasters in history, explosions at nuclear facilities at Chernobyl in the Soviet Union in 1986 and at Fukushima in Japan in 2011 forced the evacuation of thousands of people and rendered vast expanses of both countries uninhabitable.

French President Emmanuel Macron says free condoms will be available in pharmacies for any adult up to the age of 25 starting next year.

The new measure comes as the rate of sexually transmitted diseases and inflation are both on the rise in France.

Originally, Macron announced that the condoms would be available to people between the ages of 18 to 25, but he was challenged on social media about not making the condoms available to minors and he decided to expand the program to anyone up to the age of 25. 

Girls and women already receive free birth control in France.

Industry executives have joined activists and negotiators from nearly 200 countries at this month’s U.N. nature summit in Montreal, where negotiations on a global pact to protect nature could lead to tougher disclosure requirements for businesses.

Sectors such as mining, agriculture, oil and fashion are under scrutiny at the COP15 talks, due to their heavy impact on nature with activities that can contaminate soil, foul waterways or pollute the air.

As negotiators work to agree on conservation targets by the summit’s scheduled end on December 19, momentum is building for a measure to require businesses to disclose their harm to the environment.

The measure, as currently drafted, would also ask companies to halve those negative impacts by 2030, which could mean additional costs for businesses, said Franck Gbaguidi, senior analyst for energy, climate and resources at the Eurasia Group risk advisory.

But a weak deal without global agreement on how businesses should behave could also raise company costs — by opening the door to a global patchwork of different biodiversity regulations and requirements that makes compliance more difficult, Eurasia Group said in a policy statement.

Here is a look at how key sectors could be affected by the COP15 talks:

Fashion/Retail

Fashion and retail are facing pressure from consumers and governments to reduce waste and emissions throughout their operations.

For them, a strong deal that forces all companies to report any harm would work toward assuaging some consumer concerns.

In a letter to world governments in October, more than 330 companies including Swedish fashion giant H&M Group, furniture maker IKEA, British pharmaceutical and biotech company GSK and Switzerland’s Nestle came out in support of a COP15 deal that includes mandatory disclosure of companies’ environmental impacts by 2030.

Smaller companies with limited resources for monitoring and accounting could find a disclosure requirement more challenging.

Mining

For companies mining metals and coal, an environmental disclosure requirement could force companies to reveal the impacts not just from the blasting and drilling they do on site, but also from the logging and deforestation carried out in creating access roads.

Mining companies are also concerned about the central goal of the COP15 talks — to set aside 30% of Earth’s land and ocean areas for conservation by 2030. That could cut into areas rich with resources for extraction.

“There are going to be some places which are just going to be ‘no go areas’, and that can be hard for the mining sector,” said Aimee Boulanger, executive director of the Initiative for Responsible Mining Assurance.

The International Council on Mining and Metals, which represents 26 of the world’s largest mining companies, would back a deal that sets “a level playing field” with uniform rules in all regions, said the group’s chief executive, Rohitesh Dhawan.

Agriculture

With new disclosure rules, the farming sector would face an increased burden of reporting on activities like land clearing and pesticide use.

Hefty reporting obligations could burden smaller farms and ranches, some industry groups warned.

“A lot of our producers are family businesses,” said Larry Thomas, manager environment and sustainability with the Canadian Cattle Association.

The agriculture sector will likely escape a separate proposed goal to slash pesticide in half, said the Eurasia Group analyst Gbaguidi, following opposition from developing countries like Brazil, Argentina, and Paraguay due to food shortages and higher prices.

“Because of the food crisis, a lot of emerging markets are just not as open as they would have been on setting bold targets related to the agricultural sector,” Gbaguidi said.

Oil

Following COP15, oil companies are expected to ramp up their internal resources for reporting on and disclosing how oil drilling and exploration activities impact nature as well, Gbaguidi said.

The American Petroleum Institute did not respond to a request for comment on the COP15 talks.

The Canadian Association of Petroleum Producers said the country’s oil and natural gas industry wants to minimize marine and land disturbances, while also quickly restoring lands degraded by their operations to natural landscapes, CAPP spokesperson Jay Averill said.

The U.S. Department of Energy said Sunday it would announce a “major scientific breakthrough” this week, after media reported a federal laboratory had recently achieved a major milestone in nuclear fusion research.

The Financial Times reported Sunday that scientists in the California-based Lawrence Livermore National Laboratory (LLNL) had achieved a “net energy gain” from an experimental fusion reactor.

That would represent the first time that researchers have successfully produced more energy in a fusion reaction — the same type that powers the Sun — than was consumed during the process, a potentially major step in the pursuit of zero-carbon power.

Energy Department and LLNL spokespeople told AFP they could not comment or provide confirmation regarding the FT report, but said US Energy Secretary Jennifer Granholm would “announce a major scientific breakthrough” on Tuesday.

The LLNL spokesperson added that their “analysis is still ongoing.”

“We look forward to sharing more on Tuesday when that process is complete,” she said.

The fusion reaction that produced a 120 percent net energy gain occurred in the past two weeks, the FT said, citing three people with knowledge of the preliminary results.

The Washington Post later reported two people familiar with the research confirmed the development, with a senior fusion scientist telling the newspaper, “To most of us, this was only a matter of time.”

Nuclear fusion is considered by some scientists to be a potential energy of the future, particularly as it produces little waste and no greenhouse gases.

“If this fusion energy breakthrough is true, it could be a game changer for the world,” tweeted Ted Lieu, a member of Congress from California.

Fusion differs from fission, the technique currently used in nuclear power plants, by fusing two atomic nuclei instead of splitting one.

The LLNL fusion facility consists of almost 200 lasers the size of three football fields, which bombard a tiny spot with high levels of energy to initiate a fusion reaction.
