If your image of nuclear power is giant, cylindrical concrete cooling towers pouring out steam on a site that takes up hundreds of acres of land, soon there will be an alternative: tiny nuclear reactors that produce only one-hundredth the electricity and can even be delivered on a truck.

Small but meaningful amounts of electricity — nearly enough to run a small campus, a hospital or a military complex, for example — will pulse from a new generation of micronuclear reactors. Now, some universities are taking interest.

“What we see is these advanced reactor technologies having a real future in decarbonizing the energy landscape in the U.S. and around the world,” said Caleb Brooks, a nuclear engineering professor at the University of Illinois at Urbana-Champaign.

The tiny reactors carry some of the same challenges as large-scale nuclear, such as how to dispose of radioactive waste and how to make sure they are secure. Supporters say those issues can be managed and the benefits outweigh any risks.

Universities are interested in the technology not just to power their buildings but to see how far it can go in replacing the coal and gas-fired energy that causes climate change. The University of Illinois hopes to advance the technology as part of a clean energy future, Brooks said. The school plans to apply for a construction permit for a high-temperature, gas-cooled reactor developed by the Ultra Safe Nuclear Corporation, and aims to start operating it by early 2028. Brooks is the project lead.

Microreactors will be “transformative” because they can be built in factories and hooked up on site in a plug-and-play way, said Jacopo Buongiorno, professor of nuclear science and engineering at the Massachusetts Institute of Technology. Buongiorno studies the role of nuclear energy in a clean energy world.

“That’s what we want to see, nuclear energy on demand as a product, not as a big mega project,” he said.

Both Buongiorno and Marc Nichol, senior director for new reactors at the Nuclear Energy Institute, view the interest by schools as the start of a trend.

Last year, Penn State University signed a memorandum of understanding with Westinghouse to collaborate on microreactor technology. Mike Shaqqo, the company’s senior vice president for advanced reactor programs, said universities are going to be “one of our key early adopters for this technology.”

Penn State wants to prove the technology so that Appalachian industries, such as steel and cement manufacturers, may be able to use it, said Professor Jean Paul Allain, head of the nuclear engineering department. Those two industries tend to burn dirty fuels and have very high emissions. Using a microreactor also could be one of several options to help the university use less natural gas and achieve its long-term carbon emissions goals, he said.

“I do feel that microreactors can be a game-changer and revolutionize the way we think about energy,” Allain said.

For Allain, microreactors can complement renewable energy by providing a large amount of power without taking up much land. A 10-megawatt microreactor could go on less than an acre, whereas windmills or a solar farm would need far more space to produce 10 megawatts, he added. The goal is to have one at Penn State by the end of the decade.

Purdue University in Indiana is working with Duke Energy on the feasibility of using advanced nuclear energy to meet its long-term energy needs.

Nuclear reactors that are used for research are nothing new on campus. About two dozen U.S. universities have them. But using them as an energy source is new.

Back at the University of Illinois, Brooks explains the microreactor would generate heat to make steam. While the excess heat from burning coal and gas to make electricity is often wasted, Brooks sees the steam production from the nuclear microreactor as a plus, because it’s a carbon-free way to deliver steam through the campus district heating system to radiators in buildings, a common heating method for large facilities in the Midwest and Northeast. The campus has hundreds of buildings.

The 10-megawatt microreactor wouldn’t meet all of the demand, but it would serve to demonstrate the technology, as other communities and campuses look to transition away from fossil fuels, Brooks said.

One company that is building microreactors that the public can get a look at today is Last Energy, based in Washington, D.C. It built a model reactor in Brookshire, Texas that’s housed in an edgy cube covered in reflective metal.

Now it’s taking that apart to test how to transport the unit. A caravan of trucks is taking it to Austin, where company founder Bret Kugelmass is scheduled to speak at the South by Southwest conference and festival.

Kugelmass, a technology entrepreneur and mechanical engineer, is talking with some universities, but his primary focus is on industrial customers. He’s working with licensing authorities in the United Kingdom, Poland and Romania to try to get his first reactor running in Europe in 2025.

The urgency of the climate crisis means zero-carbon nuclear energy must be scaled up soon, he said.

“It has to be a small, manufactured product as opposed to a large, bespoke construction project,” he said.

Traditional nuclear power costs billions of dollars. An example is two additional reactors at a plant in Georgia that will end up costing more than $30 billion.

The total cost of Last Energy’s microreactor, including module fabrication, assembly and site prep work, is under $100 million, the company says.

Westinghouse, which has been a mainstay of the nuclear industry for over 70 years, is developing its “eVinci” microreactor, Shaqqo said, and is aiming to get the technology licensed by 2027.

The Department of Defense is working on a microreactor too. Project Pele is a DOD prototype mobile nuclear reactor under design at the Idaho National Laboratory.

Abilene Christian University in Texas is leading a group of three other universities with the company Natura Resources to design and build a research microreactor cooled by molten salt to allow for high temperature operations at low pressure, in part to help train the next generation nuclear workforce.

But not everyone shares the enthusiasm. Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists, called it “completely unjustified.”

Microreactors in general will require much more uranium to be mined and enriched per unit of electricity generated than conventional reactors do, he said. He said he also expects fuel costs to be substantially higher and that more depleted uranium waste could be generated compared to conventional reactors.

“I think those who are hoping that microreactors are going to be the silver bullet for solving the climate change crisis are simply betting on the wrong horse,” he said.

Lyman also said he fears microreactors could be targeted for a terrorist attack, and some designs would use fuels that could be attractive to terrorists seeking to build crude nuclear weapons. The UCS does not oppose using nuclear power, but wants to make sure it’s safe.

The United States does not have a national storage facility for storing spent nuclear fuel and it’s piling up. Microreactors would only compound the problem and spread the radioactive waste around, Lyman said.

A 2022 Stanford-led study found that smaller modular reactors — the next size up from micro — will generate more waste than conventional reactors. Lead author Lindsay Krall said this week that the design of microreactors would make them subject to the same issue.

Kugelmass sees only promise. Nuclear, he said, has been “totally misunderstood and under leveraged.” It will be “the key pillar of our energy transformation moving forward.”

The two Sudanese women thought they had malaria and were taking their medication, but things took a dire turn. Both complained of a splitting headache and fever that didn’t respond to the antimalaria treatment.

By the time she was diagnosed with dengue fever, Raqiya Abdsalam was unconscious.

“Soon after they examined me, I fell into a coma,” she said, recounting her ordeal some three months ago. Both women have since recovered and are at home in the city of El Obeid in the central province of North Kordofan.

For decades, Sudan’s underfunded public health sector has struggled to effectively diagnose or treat patients as significant government spending went to its vast security services. A recent spike in mosquito-borne diseases — such as dengue fever and malaria — has underscored the fragility of the African country’s health system, boding ill for future challenges driven by climate change.

Sudan’s best-equipped hospitals are concentrated in the capital, Khartoum, leaving those from far-flung provinces reliant on aid projects. But many of those have disappeared.

In October 2021, Sudan’s leading military figure, Gen. Abdel-Fattah Burhan, led a coup that derailed the country’s short-lived democratic transition. The move spurred a sharp reduction in aid, with the U.N Office for the Coordination of Humanitarian Affairs reporting that funding levels fell to less than 50% of required needs for both 2021 and 2022.

Burhan with his ruling generals and several other political forces pledged in December to install a new civilian government. But political wrangling is impeding a final deal, and it remains unclear when — and if — donor funding will return to previous levels.

In late fall, a young doctor at a North Kordofan hospital thought that what she was seeing was a new malaria outbreak. Patients arriving at her hospital had malaria-like symptoms — high fever, body fatigue and a migraine-like headache.

But after blood samples were sent to a laboratory in Khartoum for testing, a worrisome picture emerged. Some of the patients did have malaria, which is caused by a parasite, but others had dengue fever — similar in symptoms but caused by a virus. If severe and untreated, dengue fever can lead to organ failure and death.

The young physician said the hospital lacked the facilities to deal with the outbreak. “Patients had to either lie on the floor or bring their own beds to the hospital,’’ she said.

While malaria is common across central and southern Sudan, large dengue outbreaks are rare. But last fall and winter, dengue fever spread to 12 of the country’s 18 provinces, killing at least 36 people and infecting more than 5,200, according to Sudan’s Ministry of Health. However, the actual numbers are likely higher, given the limitations on testing.

‘‘Most hospitals outside of Khartoum are not connected to the Ministry of Health database,’’ said Alaaeldin Awad Mohamed Nogoud, a liver and transplant surgeon who is also a prominent pro-democracy activist.

The World Health Organization says several factors enabled the dengue outbreak, including the absence of disease surveillance infrastructure and heavy flooding in autumn. The stagnant water allowed mosquitoes to breed and fueled the spread of the disease.

Health experts also fear that growing mosquito migration, induced by climate change, could spur new surges in dengue fever, among other tropical diseases typically found beyond Sudan’s southern borders. The Aedes aegypti, a long-legged mosquito growing in number across Sudan that can carry the dengue virus, is causing particular concern.

According to Anne Wilson, an epidemiologist at the Liverpool School of Tropical Medicine, containing illnesses spread by the Aedes aegypti is difficult because it mostly bites during the day, rendering insecticide-treated nets, similar to mosquito nets for beds, less effective.

Sudan’s public hospitals are state-run, but patients often still pay for drugs and tests. Hospitals in rural areas are the most depleted, stocked with little more than metal-frame beds and doctors.

In North Kordofan — the site of the recent dengue outbreak — some believe the virus went unchecked for months due to a widespread lack of blood testing equipment. Abdsalam and Amany Adris, the two women from El Obeid, said several doctors had told them they had malaria before they were correctly diagnosed.

After the Ministry of Health officially recognized the outbreak in November, officials say free testing and treatment were made available to dengue fever patients. And by January, North Kordofan was declared free of dengue fever.

But even after that announcement, the young doctor from the province said she was treating suspected cases. Few patients can afford to pay for the blood tests themselves, however, she added.

Both Nogoud and the young physician said widespread shortages are forcing physicians to go to black market for basic medicines, such as paracetamol IV drips to treat fever.

For years, Sudan has been in an economic crisis with annual inflation topping 100% on most months. Since 2018, the Sudanese pound has lost over 95% of its value against the dollar, making it difficult to buy pharmaceuticals or medical equipment from abroad.

By the end of last year, Sudan’s National Medical Supplies Fund — the body tasked with procuring pharmaceuticals — said the availability of cancer drugs stood at 48% of needed levels, and other emergency medication was at 68%. Doctors, working with little pay and in difficult conditions, have regularly gone on strike.

Critics accuse the country’s leaders of not putting more funds towards the health sector. The federal budget for 2021, listed on the government’s website, said the country’s health ministry would receive less than half of what would be allocated to the Sudanese Armed Forces and the Rapid Support Forces, the country’s largest paramilitary group. The military spokesperson did not respond to AP’s request for comment.

With few resources, the Health Ministry has turned to short videos on social media, encouraging people in a catchy song to cover standing water sources and install netting on windows.

Few see this as a long-term solution.

“The whole country is in a state of chaos,” said Nada Fadul, an infectious diseases physician and associate of the Sudanese non-governmental organization NexGen.

“Health care might not become the priority for survival,” Fadul added.

A single-injection antiviral treatment for newly infected COVID-19 patients reduced the risk of hospitalization by half in a large-scale clinical trial, a study published Wednesday said.

Stanford University professor Jeffrey Glenn, co-author of the study published in the New England Journal of Medicine, said the new drug “showed profound benefits for vaccinated and unvaccinated people alike.”

While the number of Americans dying daily of the disease caused by a coronavirus has fallen to about 500, treatments for COVID-19 remain limited. One of the most common — Paxlovid, made by Pfizer — involves taking 30 pills over five days.

The new treatment involves a single dose of pegylated interferon lambda, a synthetic version of a naturally occurring protein that infected cells secrete to defend against viral infection.

“What it does is it binds receptors on the surfaces of cells that activate our own antiviral defense mechanisms,” said Glenn, a professor of medicine, microbiology and immunology who heads the Stanford Biosecurity and Pandemic Preparedness Initiative.

“So if a virus has infected the cell, it will turn on processes that aim to destroy the virus’s replication,” he said. “It will also send signals to neighboring cells to warn them viruses are on their way and get ready to defend yourself.”

Receptors for interferon lambda are primarily in the linings of the lungs, airways and intestine — the main places COVID-19 strikes.

“We’re turning on these antiviral mechanisms in the cells, the lung, where the infection is happening,” Glenn said.

The phase three trial of the drug, conducted from June 2021 to February 2022, involved nearly 2,000 patients with COVID symptoms in Brazil and Canada, about 85 percent of whom had been vaccinated.

A total of 931 newly infected COVID patients were given a single injection of interferon lambda, while 1,018 participants were given a placebo.

The risk of COVID-19–related hospitalization or death from any cause was 47 percent lower in the interferon group than in the placebo group, according to the researchers.

Twenty-five of the 931 people who received the injection within seven days of exhibiting COVID symptoms were hospitalized, compared with 57 of the 1,018 who received the placebo.

Vaccinated patients treated with interferon lambda experienced a 51 percent reduction in hospitalization relative to the placebo group.

There was an 89 percent reduction in hospitalization among unvaccinated patients treated within the first three days of the onset of COVID symptoms compared with the placebo group.

Developed for hepatitis D

Glenn said interferon lambda proved effective against all COVID variants tested, including omicron, and side effects in the group receiving the injections were no greater than among the placebo recipients.

Glenn is the founder of a small biotechnology company called Eiger Biopharmaceuticals that acquired interferon lambda to develop drugs for the hepatitis delta virus.

“When COVID came, I said this would be the perfect drug for COVID,” said Glenn, who left the Palo Alto company but remains on the board of directors and is an equity holder.

Eiger sought an emergency use authorization for interferon lambda from the U.S. Food and Drug Administration for COVID treatment last year, but it was not granted.

That was “very frustrating,” Glenn said, though he was hopeful that publication of the study in the New England Journal of Medicine “will help encourage regulators here and around the world to find a way to get lambda into patients as soon as possible.”

Whether out-of-the-box thinking or a sign of desperation, scientists on Wednesday proposed the regular transport of moon dust to a point between Earth and Sun to temper the ravages of global warming. 

Ideas for filtering solar radiation to keep Earth from overheating have been kicking around for decades, ranging from giant space-based screens to churning out reflective white clouds. 

But the persistent failure to draw down planet-warming greenhouse gas emissions has pushed once-fanciful geoengineering schemes toward center stage in climate policy, investment and research. 

Blocking 1%-2% of the Sun’s rays is all it would take to lower Earth’s surface by a degree or two Celsius, roughly the amount it has warmed over the last century. 

The solar radiation technique with the most traction so far is the 24/7 injection of billions of shiny sulfur particles into the upper atmosphere. 

So-called stratospheric aerosol injection would be cheap, and scientists know it works because major volcanic eruptions basically do the same thing. When Mount Pinatubo in the Philippines blew its top in 1991, it lowered temperatures in the northern hemisphere by about 0.5 Celsius for nearly a year. 

But there are serious potential side-effects, including the disruption of rain patterns upon which millions depend for growing food.  

However, a new study in the peer-reviewed journal PLOS Climate explores the possibility of using moon dust as a solar shield. 

A team of astronomers applied methods used to track planet formation around distant stars — a messy process that kicks up vast quantities of space dust — to Earth’s moon. 

Computer simulations showed that putting lunar dust at a gravitational sweet spot between Earth and Sun “blocked out a lot of sunlight with a little amount of mass,” said lead author Ben Bromley, a professor of physics at the University of Utah. 

‘Balancing marbles’ 

The scientists tested several scenarios involving different particle properties and quantities in different orbits, looking for the one that would throw the most shade. 

Moon dust worked best. The quantities needed, they said, would require the equivalent of a major mining operation on Earth. 

The authors stressed that their study was designed to calculate potential impact, not logistical feasibility. 

“We aren’t experts in climate change or rocket science,” said co-author Benjamin Bromley, a professor at the Harvard-Smithsonian Center for Astrophysics. 

“We were just exploring different kinds of dust on a variety of orbits to see how effective this approach might be,” he added. “We don’t want to miss a game changer for such a critical problem.” 

Experts not involved in the study praised its methodology but doubted whether it would actually work. 

“Placing moon dust at the gravity midpoint between Earth and Sun, can indeed reflect heat,” said University of Edinburgh professor Stuart Haszeldine. 

“But this is like trying to balance marbles on a football — within a week most dust has spun out of stable orbit.” 

For Joanna Haigh, an emeritus professor of atmospherics at Imperial College London, the study is a distraction. 

The main problem, she said, “is the suggestion that the implementation of such schemes will solve the climate crisis whereas it just gives polluters an excuse not to act.”

The small distant world called Quaoar, named after a god of creation in Native American mythology, is producing some surprises for astronomers as it orbits beyond Pluto in the frigid outer reaches of our solar system.

Researchers said Wednesday they have detected a ring encircling Quaoar akin to the one around the planet Saturn. But the one around Quaoar defies the current understanding of where such rings can form – located much further away from it than current scientific understanding would allow.

The distance of the ring from Quaoar places it in a location where scientists believe particles should readily come together around a celestial body to form a moon rather than remain as separate components in a disk of ring material.

“This is the discovery of a ring located in a place that should not be possible,” said astronomer Bruno Morgado of the Valongo Observatory and the Federal University of Rio de Janeiro in Brazil, lead author of the study published in the journal Nature.

Discovered in 2002, Quaoar is currently defined as a minor planet and is proposed as a dwarf planet, though it has not yet been formally given that status by the International Astronomical Union, the scientific body that determines such things.

Its diameter of about 1,110 kilometers is about a third that of Earth’s moon and half that of the dwarf planet Pluto. It has a small moon called Weywot, Quaoar’s son in mythology, with a diameter of 170 kilometers, orbiting beyond the ring.  

Inhabiting a distant region called the Kuiper belt populated by various icy bodies, Quaoar orbits about 43 times further than Earth’s distance to the sun. In comparison, Neptune, the outermost planet, orbits about 30 times further than Earth’s distance from the sun, and Pluto about 39 times further.

Quaoar’s ring was spotted using the European Space Agency’s orbiting Cheops telescope, whose primary purpose is to study planets beyond our solar system, as well as ground-based telescopes.

The ring, a clumpy disk made of ice-covered particles, is located about 4,100 kilometers away from Quaoar’s center, with a diameter of about 8,200 kilometers.

“Ring systems may be due to debris from the same formation process that originated the central body or may be due to material resulting after a collision with another body and captured by the central body. We do not have hints at the moment on how the Quaoar ring formed,” said astronomer and study co-author Isabella Pagano, director of Italian research institute INAF’s Astrophysical Observatory of Catania.

Unlike any other known ring around a celestial body, Quaoar’s is located outside what is called the Roche limit. That refers to the distance from any celestial body possessing an appreciable gravitational field within which an approaching object would be pulled apart. Material in orbit outside the Roche limit would be expected to assemble into a moon.

Saturn has the largest ring system in our solar system. The other large gas planets – Jupiter, Uranus and Neptune – all have rings, though less impressive, as do the non-planetary bodies Chariklo and Haumea. All reside inside the Roche limit.

But how can Quaoar flout this rule?

“We considered some possible explanations: a ring made of debris, resulting from a putative disruptive impact into a Quaoar moon, would survive for a very short time – but the probability to observe that is extremely low,” Pagano said.

“Another possibility is that theories for the aggregation of icy particles need to be revised, and particles might not always aggregate into larger bodies as quickly as one might expect.”

Mexican police detained a medical doctor accused of using infected medicines that may have caused a mysterious meningitis outbreak in northern Durango state, after the disease killed at least 35 women in recent months.

Another 79 people have been hospitalized with signs of infection.

Police arrested the doctor who specializes in anesthesiology early Tuesday morning on charges of illegal practices including the re-use of medications at the private hospitals where he worked. The doctor’s full name was not disclosed.

Meningitis is typically associated with painful inflammation of the brain and spinal cord, often caused by a virus or in some cases bacteria or a fungal infection.

The affected patients in Durango were likely infected by fungal meningitis while having procedures in the same hospitals where the doctor worked, according to Durango state prosecutor Sonia Garza.

She told reporters at a news conference on Tuesday in the state capital that the first procedures associated with the infected patients took place last August and that many of them had been administered anesthesia for obstetric procedures.

“This specialist carried out procedures with no restraint,” said Garza, adding that he brought his own medication for patients, including unauthorized controlled drugs.

The outbreak has raised concern in both Mexico and from international bodies after the outbreak’s first death was confirmed last November.

Garza added that the detained doctor was the only physician who conducted procedures at the four hospitals where the infections have been observed. She said that he denied using his own medications at a hearing before prosecutors.

Reuters was not immediately able to request comment from the doctor, or locate his lawyer, but his son, contacted by Reuters, said his father is innocent.

“They accused my father without any evidence,” he said, declining to provide his name.

The meningitis outbreak is confined to private hospitals in the state capital, also known as Durango, according to Mexico’s health ministry.

Black and Hispanic adults on dialysis experience more staph bloodstream infections than white patients receiving the treatment for kidney failure, U.S. health officials said Monday.

The U.S. Centers for Disease Control and Prevention (CDC), citing 2017-2020 data, said adults on dialysis for end-stage kidney disease (ESKD) were 100 times more likely to have a Staphylococcus aureus bloodstream infection than adults not receiving the treatment.

According to the CDC, more than 800,000 people in the United States live with ESKD. Seventy percent are being treated with dialysis and 30% have a functioning kidney transplant.

African Americans constitute some 33% of all U.S. dialysis patients although they make up only 12% of the population.

About one in every five dialysis patients is Hispanic.

Members of both groups have significantly higher rates of staph bloodstream infections than white patients on dialysis, the CDC said, with Hispanic patients experiencing a 40% higher risk.

The CDC said the higher prevalence of ESKD among Blacks and Hispanics is due in part to underlying conditions such as hypertension and diabetes.

Needles and catheters are used to connect patients to dialysis machines that clean their blood, and bacterial infections such as staph can enter a patient’s bloodstream.

Some staph infections are resistant to common antibiotics, making them particularly deadly.

The CDC said bloodstream infections in dialysis patients in the United States have decreased since 2014 but more needs to be done to prevent them.

“Preventing staph bloodstream infections begins by detecting chronic kidney disease in its early stages to prevent or delay the need for dialysis,” CDC chief medical officer Debra Houry said in a statement.

“Health care providers can promote preventative practices, including methods to manage diabetes and high blood pressure, as well as providing education on treatment options,” Houry said.

The CDC said 4,840 dialysis facilities reported 14,822 bloodstream infections in 2020 and 34% of them were due to staph.

South Africa has recorded two confirmed imported cases of cholera, the health department said Sunday, as it called for vigilance. 

The cases were of sisters who had in January traveled to Malawi, where a cholera outbreak since last year has claimed more than 1,000 lives as of January, the highest on record in the country. 

“Both patients had developed symptoms on their return to Johannesburg,” the health department said in a statement. 

“A close contact (household family member) of one of the patients was admitted to hospital on 4 February with diarrhea and dehydration, and is considered a possible case,” it said, adding laboratory test results were pending. 

Cholera is an acute diarrheal infection caused by the bacteria Vibrio cholerae and can be deadly if left untreated. It is mainly spread by contaminated food and water. 

Cholera is not endemic in South Africa, the health department said. The last outbreak in the country was in 2008-2009 when about 12,000 cases were reported following an outbreak in neighboring Zimbabwe which led to a surge of imported cases and subsequent local transmission.

The thermometer sinks below zero as a blizzard of fine snow descends on two houses freshly built inside a massive laboratory in northern England.

Despite the icy conditions, the two energy-efficient homes remain cozy and warm due to their use of cutting-edge heating and insulation technology.

Welcome to Energy House 2.0 — a science experiment designed to help the world’s housebuilders slash carbon emissions, save energy and tackle climate change.

The project, based in a laboratory resembling a giant warehouse on Salford University campus near the center of Manchester, opened last month.

Rain, wind, sunshine and snow can be recreated in temperatures ranging from 40 degrees Celsius to –20 Celsius, operated from a control center.

Replicating weather

“What we’ve tried to achieve here is to be able to replicate the weather conditions that would be experienced around 95% of the populated Earth,” Professor Will Swan, head of energy house laboratories at the university, told AFP.

The facility, comprising two chambers that can experience different weather at the same time, will test types of housing from all over the world “to understand how we deliver their net-zero and energy-efficient homes,” he added.

The two houses, which are quintessentially British and constructed by firms with U.K. operations, will remain in place for a few years.

Other builders will then be able to rent space in the lab to put their own properties under the spotlight.

The project’s first house was built by U.K. property firm Barratt Developments and French materials giant Saint-Gobain.

It is clad with decorative bricks over a frame of wood panels and insulation, with solar panels on the roof.

Scientists are examining the efficiency of several different types of heating systems, including air-source heat pumps.

In the living room, a hot-water circuit is located along the bottom of the walls, while further heat is provided via infrared technology in the molding and from a wall panel.

Mirrors also act as infrared radiators while numerous sensors monitor which rooms are in use.

Residents will be able to manage the technology via one single control system similar to Amazon’s voice-activated Alexa interface.

Builders estimate the cutting-edge tech will mean that the energy bill will be just one quarter of what the average U.K. home currently pays, a boon to customers reeling from sky-high energy prices.

It will also make an important contribution to Britain’s efforts to reach zero carbon emissions by 2050 to combat climate change.

A parliamentary report found that, in 2019, 17% of heating emissions from buildings came from homes — making their contribution similar to all the petrol and diesel cars driving on Britain’s roads.

Environmental campaigners have long called on the U.K. government to increase energy efficiency and insulation support for existing homes across Britain.

‘Alexa of home energy’

“One of the key technologies that we’re trying on this house is almost like a building management system for residential buildings,” said Tom Cox, U.K. technical director at Saint-Gobain.

“It’s almost like the Alexa of the home energy system — and that can be automated as much as the occupant wants.”

And now with their mega-laboratory, scientists and companies no longer have to wait for extreme swings in the weather.

“We can test a year’s worth of weather conditions in a week,” added Cox.

The “ultimate goal is to create that environment which is comfortable and cost effective and commercially viable to deliver,” added Cox.

“At the same time (we are) addressing the sustainability issues that we have in construction.”

As it marks World Cancer Day, the World Health Organization is calling for action to tackle breast cancer, the most common and leading cause of cancer deaths among women.

Every year, more than 2.3 million women are diagnosed with breast cancer, and nearly 700,000 die of the disease, which disproportionately affects women living in low- and middle-income countries.

WHO officials say women who live in poorer countries are far less likely to survive breast cancer than women in richer countries.   

“Breast cancer survival is 50 percent or less in many low- and middle-income countries, and greater than 90 percent for those able to receive the best care in high income countries,” says Bente Mikkelsen, director of the Noncommunicable Diseases Department at the WHO.

She says the odds are stacked against women who live in poor countries, noting many must sell their assets to pay for the treatment they need.   

She notes that women also are discouraged from seeking and receiving a timely diagnosis for their condition because of the stigma attached to breast cancer.   

“A woman subjected to racial and ethnic disparities will receive lower quality care and be forced to abandon treatment,” she says.

WHO data show more than 20 high income countries have successfully reduced breast cancer mortality by 40 percent since 1990. It finds five-year survival rates from breast cancer in North America and western Europe is better than 95 percent, compared to 66 percent in India and 40 percent in South Africa.

Mikkelsen says by closing the rich-poor inequity gap, some 2.5 million lives could be saved over the next two decades.

“Time is, unfortunately, not on our side. Breast cancer will be a larger public health threat for tomorrow, and the gap in care will continue to grow.  

She says that “by the year 2040, more than 3 million cases and 1 million deaths are predicted to occur each year worldwide. Approximately 75 percent of these deaths will occur in low- and middle-income countries.”

Coinciding with World Cancer Day, the WHO is launching a global breast cancer initiative to tackle the looming threat. The initiative contains a series of best practices for addressing this significant public health issue.

The strategy rests on three main pillars: early-detection programs so at least 60 percent of breast cancers are diagnosed and treated as an early-stage disease; starting treatment within three months of diagnosis; managing breast cancer to ensure at least 80 percent of patients complete their recommended treatment.

Tedros Adhanom Ghebreyesus, the director-general of the WHO, says, “Countries with weaker health systems are least able to manage the increasing burden of breast cancer … so, it must be a priority for ministries of health and governments everywhere.

“We have the tools and the knowhow to prevent breast cancer and save lives,” he says.   

Benjamin Anderson, medical officer and lead of the WHO’s global breast cancer initiative, says one of the best ways to implement the initiative is through primary health care systems.   

“The patient pathway is the basis of the three pillars of the global cancer initiative framework. What we anticipate is that by using awareness, education in the public, combined with professional education, it sets us up for the diagnostic processes that must take place and the treatment that has to follow.”  

The World Health Organization warns failure to act now to address cancer in women, including breast cancer, will have serious intergenerational consequences.

It cites a study by the International Agency for Research on Cancer that reported that because of “the estimated 4.4 million women who died from cancer in 2020, about 1 million children became maternal orphans in that year,” 25 percent of which was due to breast cancer.

Mikkelsen observes, “the children whose mothers die from cancer experience health and educational disadvantages throughout their lives.”

WHO officials acknowledge the cost of drugs to treat breast cancer could be a matter of life or death. It notes the price of certain oral drugs is less than $1, while others range from $9,000 to $10,000.

As many countries are unable to negotiate prices, they say the WHO is working to increase the availability and affordability of breast cancer medication.

The U.N. special rapporteur for Myanmar warned Tuesday that two years after its coup, Myanmar’s military will try to legitimize its hold on power through sham elections this year, and he urged the international community not to recognize or engage with the junta.

Humanitarians await ‘guidelines’ from Afghan Taliban on women aid workers

The U.N. humanitarian chief said Monday he is awaiting a list of guidelines from Taliban authorities to allow Afghan women to work in the humanitarian sector, following a decree last month that has restricted their work. Martin Griffiths said he also asked Taliban officials if they are not going to rescind their decree now, then they should extend exemptions to cover all aspects of humanitarian work.

Iran dismisses IAEA report

Iran’s atomic energy organization on Wednesday dismissed a report by the United Nations nuclear watchdog that said Tehran had made an undeclared change to uranium enriching equipment at its Fordow plant. The IAEA said its inspectors found a modification to an interconnection between two clusters of centrifuges that was substantially different than what Iran had declared.

Red Cross warns world dangerously unprepared for next pandemic

The International Federation of Red Cross and Red Crescent Societies warned Monday in its World Disaster Report that the world is dangerously unprepared for the next pandemic, and this will have severe health, economic and social consequences for countries around the world.

In brief 

— The World Health Organization said Monday that COVID-19 continues to be a global health emergency. Following a meeting of the International Health Regulations Emergency Committee on January 27, WHO Chief Dr. Tedros Adhanom Ghebreyesus said the pandemic is probably at a transition point that must be carefully navigated. The committee offered temporary recommendations including continuing vaccinations especially for high-risk groups. The health agency says as of January 29 there have been more than 753 million confirmed COVID-19 cases and over 6.8 million deaths globally.

— WHO also launched a new initiative Friday to reach the target of saving 2.5 million women’s lives from breast cancer by 2040. The campaign seeks to promote early detection, timely diagnosis and comprehensive management of breast cancer. WHO says there are more than 2.3 million cases of breast cancer annually, making it the most common cancer among adults. In 95% of countries, breast cancer is the first or second leading cause of female cancer deaths. Survival rates vary dramatically both between and within countries, with nearly 80% of deaths from both breast and cervical cancer occurring in low- and middle-income countries. Saturday is World Cancer Day.

— The Food and Agriculture Organization said Friday that global food commodity prices had dropped in January for the 10th consecutive month. The FAO Food Price Index averaged 131.2 points in January, 0.8% lower than in December and 17.9% below its peak in March 2022. The price indices for vegetable oils, dairy and sugar drove the January decline, while those for cereals and meat remained largely stable. Wheat prices were down by 2.5% as production in Australia and Russia outperformed expectations. The FAO said low domestic prices could result in a small cutback in wheat plantings in Russia, the world’s largest exporter, while the impact of the Kremlin’s war in Ukraine are estimated to reduce winter wheat area plantings by 40%. Record plantings are forecast in India.

— The U.N. said that an inter-agency aid convoy delivered five truckloads of medications, shelter materials, tool kits, hygiene items and solar lamps to the Zaporizhzhia region in the southeast Ukraine on Thursday. The supplies are headed for people in Huliaipole, where about 3,000 people remain close to the front line. Humanitarians say the community has been without electricity and water since March, as power stations were damaged by fighting and cannot be repaired because of the ongoing hostilities. This is the second convoy this week to reach frontline communities, after a convoy reached Donetsk region on January 31. U.N. humanitarian chief Martin Griffiths will brief the U.N. Security Council on the humanitarian situation on February 6.

What we are watching next week

On February 6, U.N. Secretary-General Antonio Guterres will brief member states on his priorities for the year ahead. With the world facing conflicts, inflation and climate catastrophes, look for him to amplify his calls for unity and urgent action.

Logistics manager Nicholas Rehak was visiting his parent’s home in Baltimore County, Maryland, several years ago. He was standing on the back deck one night when he noticed a bluish white light.

“It was shaped in a damn near perfect oval and it started to rise,” Rehak told VOA. “I’m talking straight up vertical, no deviation. It sat there for nearly 30 seconds and then suddenly it vanished — like a lamp when someone pulls the plug. Just sudden darkness.”

Perhaps it was a drone. Rehak said that was his first thought.

“But I’ve never seen a drone take off perfectly vertical like that, from ground to sky without so much as a wobble,” he continued. “It was far too low to the ground to be a larger aircraft. So what was it? If I close my eyes, I can still see the light plain as day.”

For decades, Americans have reported sighting unidentified flying objects — commonly referred to as UFOs — zigging, zagging and hovering in the sky. Many were ridiculed for their assertions.

Now, however, the U.S. government is tracking and studying reports of what they refer to as unidentified aerial phenomena (UAP). More than 350 new cases have been reported to the government since March 2021, according to an unclassified document released last month by the Office of the Director of National Intelligence. That number far exceeds what was reported over the 17 years prior, suggesting either a dramatic increase in sightings or a greater willingness to report them.

“It’s no longer embarrassing to talk about,” said Steve Mort, a New Orleans, Louisiana, resident. “I’ve always known true extraterrestrial UAPs exist — they’re likely our ancestors checking back in on us. The only thing I’m shocked by is that the government is officially confirming this.”

The January report, however, cautions against making such conclusions. While approximately half of the 366 reported UAP sightings remain unexplained, the ODNI wrote its “initial characterization does not mean positively resolved or unidentified.”

In other words, the U.S. government says it does not know what many of the mysterious objects are. And while the Department of Defense and NASA are taking steps to investigate UAPs, an impatient and imaginative American public is debating the mystery on its own.

Extraterrestrial life

Many in the scientific community say there is nothing particularly unusual about the steps the government is taking.

This includes American astrophysicist Neil deGrasse Tyson.

“If there’s something in your night sky and you don’t know what it is, maybe it’s harmful, right?” Tyson said, speaking with VOA. “Well, investigating that potential harm is the entire mission statement of the military.”

“It’s nothing deeper than that,” he continued, “other than there are many people out there who wish it was something deeper despite having a lack of evidence to prove it.”

While there is a wide variety of opinions on whether extraterrestrial life has visited Earth, there appears to be a consensus that life likely exists beyond Earth.

According to a survey conducted by the Pew Research Center in June 2021, 65% of Americans say they believe intelligent life exists on other planets.

“Each time we build a bigger telescope, we discover more and more galaxies in our ever-expanding universe,” said Robert Sheaffer, an author and investigator of UAPs. “Our universe is so unimaginably vast, it would be foolish to claim there are no other planets with life, or with intelligent civilizations.”

Differing conclusions

Americans as a whole appear divided on whether UAPs are extraterrestrial spacecraft visiting our planet. But the percentage who do believe in alien visitation has grown.

A YouGov survey last September found 34% of Americans believe UFOs are alien ships or alien life forms. An equal percentage said they didn’t know what accounts for UFOs while 32% believed they had a natural scientific explanation.

In a similar survey by Newsweek/Princeton in 1996, only 20% of Americans believed UFOs were evidence of extraterrestrial life while 51% said they could be explained by natural science.

Tyler Ogilvie, a musician from Syracuse, New York, said he recently spotted a mysterious spacecraft zooming overhead.

“I was legitimately convinced I was seeing something mystical or otherworldly,” he told VOA. “It was incredible … until a sobering Google search proved otherwise. It turned out I was looking at Elon Musk’s Starlink [a series of satellites launched by SpaceX to provide broader internet access].”

“But I think it’s a valuable experience,” Ogilvie added. “I learned how quickly the human mind can be convinced of something that it wants to believe is true. I want to believe it because I think it would make more sense out of our seemingly meaningless existence if we could put it into the perspective of the universe as a whole.”

Others agree.

“I think we don’t want to be alone,” Nicholas Rehak said.

“It gives me goosebumps to dream of what might be out there,” said Carl Fink, a software developer in New Orleans, “and contemplating the cosmos helps me consider the possibility of things I couldn’t previously imagine.”

Tyson said imagining life in other parts of the universe is part of a longer trend in human history.

“We used to think our planet was the center of the cosmos, but then through the help of Galileo and others we learned we orbit a sun,” the astrophysicist explained. “But at least everything in the universe orbited our sun … until we learned it didn’t. We’d go on to learn that other stars in the galaxy have their own planets, and that, in fact, there are hundreds of billions of other galaxies in our universe and we’re not at the center of anything.”

He added, “It’s good for our ego to understand that the universe literally doesn’t revolve around us and that we’re probably not the only life form out there.”

‘Where is the evidence?’

Are the UAPs being reported to the U.S. government in record numbers proof that alien life forms are finally reaching out?

Tyson is a skeptic.

“You’re telling me that a million humans are airborne at any given time — with cellphones that can take photos and capture video — and none of us have gotten clearer footage of these supposed alien spacecraft?” he said. “We have the technology to livestream these encounters, so where is the evidence? I know, I know. Everyone wants to meet the aliens, but for me — and I don’t want to stop anyone from investigating the lights in the sky, of course — there’s not enough evidence of visiting aliens to pique my interest.”

The Pentagon office responsible for tracking and studying sightings has preliminarily identified 163 of the recent reports as “balloon or balloon entities” while others have been attributed to weather events, birds, drones, or airborne debris such as plastic bags.

Still, 171 other reported sightings since March 2021 remain unexplained. Are they aliens? Foreign governments spying on America? Secret U.S. weapons tests?

“UAPs can be anything,” said Emily Songster, a music teacher in Asheville, North Carolina. “But imagining the possibility of life on other planets coming to visit us makes for a more fun and interesting world. I think that’s why many people look to aliens for answers and, personally, I’m glad we’re beginning to officially take these things seriously.”
…

More than 200 years after Napoleon met defeat at Waterloo, the bones of soldiers killed on that famous battlefield continue to intrigue Belgian researchers and experts, who use them to peer back to that moment in history.

“So many bones — it’s really unique!” exclaimed one such historian, Bernard Wilkin, as he stood in front of a forensic pathologist’s table holding two skulls, three femurs and hip bones.

He was in an autopsy room in the Forensic Medicine Institute in Liege, eastern Belgium, where tests are being carried out on the skeletal remains to determine from which regions the four soldiers they belong to came from.

That in itself is a challenge.

Half a dozen European nationalities were represented in the military ranks at the Battle of Waterloo, located 20 kilometers (12 miles) south of Brussels.

That armed clash of June 18, 1815 ended Napoleon Bonaparte’s ambitions of conquering Europe to build a great empire, and resulted in the deaths of around 20,000 soldiers.

The battle has since been pored over by historians, and — with advances in the genetic, medical and scanning fields — researchers can now piece together pages of the past from the remains buried in the ground.

Some of those remains have been recovered through archeological digs, such as one last year that allowed the reconstitution of a skeleton found not far from a field hospital the British Duke of Wellington had set up.

But the remains examined by Wilkin surfaced through another route.

‘Prussians in my attic’

The historian, who works for the Belgian government’s historical archives, said he gave a conference late last year and “this middle-aged man came to see afterwards and told me, ‘Mr Wilkin, I have some Prussians in my attic'”.

Wilkin, smiling, said the man “showed me photos on his phone and told me someone had given him these bones so he can put them on exhibit… which he refused to do on ethical grounds”.

The remains stayed hidden away until the man met Wilkin, who he believed could analyze them and give them a decent resting place.

A key item of interest in the collection is a right foot with nearly all its toes — that of a “Prussian soldier” according to the middle-aged man.

“To see a foot so well preserved is pretty rare, because usually the small bones on the extremities disappear into the ground,” noted Mathilde Daumas, an anthropologist at the Universite Libre de Bruxelles who is part of the research work.

As for the attributed “Prussian” provenance, the experts are cautious.

The place it was discovered was the village of Plancenoit, where troops on the Prussian and Napoleonic sides bitterly fought, Wilkin said, holding out the possibility the remains might be those of French soldiers.

Scraps of boots and metal buckles found among the remains do point to uniforms worn by soldiers from the Germanic side arrayed against the French.

But “we know that soldiers stripped the dead for their own gear,” the historian said.

Clothes and accessories are not reliable indicators of the nationality of skeletons found on the Waterloo battlefield, he stressed.

DNA testing

More dependable, these days, are DNA tests.

Dr Philippe Boxho, a forensic pathologist working on the remains, said there were still parts of the bones that should yield DNA results, and he believed another two months of analyses should yield answers.

“As long as the subject matter is dry we can do something. Our biggest enemy is humidity, which makes everything disintegrate,” he explained.

The teeth in particular, with traces of strontium, a naturally occurring chemical element that accumulates in human bones, can point to specific regions through their geology, he said.

Wilkin said an “ideal scenario” for the research would be to find that the remains of the “three to five” soldiers examined came from both the French and Germanic sides.

The Biden administration took a first step Friday toward ending federal protections for grizzly bears in the northern Rocky Mountains, which would open the door to future hunting in Montana, Wyoming and Idaho.

The U.S. Fish and Wildlife Service said state officials provided “substantial” information that grizzlies have recovered from the threat of extinction in the regions surrounding Yellowstone and Glacier national parks.

But federal officials rejected claims by Idaho that protections should be lifted beyond those areas, and they raised concerns about new laws from the Republican-led states that could potentially harm grizzly populations.

“We will fully evaluate these and other potential threats,” said Martha Williams, director of the U.S. Fish and Wildlife Service.

Friday’s move kicks off at least a year of further study before final decisions about the Yellowstone and Glacier regions.

State officials have insisted any future hunts would be limited and not endanger the overall population.

However, Republican lawmakers in the region in recent years also adopted more aggressive policies against gray wolves, including loosened trapping rules that could lead to grizzlies being inadvertently killed.

As many as 50,000 grizzlies once roamed the western half of the U.S. They were exterminated in most of the country early last century by overhunting and trapping, and the last hunts in the northern Rockies occurred decades ago. There are now more than 2,000 bears in the Lower 48 states and much larger populations in Alaska, where hunting is allowed.

The species’ expansion in the Glacier and Yellowstone areas has led to conflicts between humans and bears, including periodic attacks on livestock and sometimes fatal maulings of humans.

Montana Gov. Greg Gianforte welcomed the administration’s announcement and said it could lead to the state reclaiming management of a species that’s been under federal protections since 1975. He said the grizzly’s recovery “represents a conservation success.”

The federal government removed protections for the Yellowstone ecosystem’s grizzlies in 2017. Wyoming and Idaho were set to allow grizzlies to be hunted when a judge restored those protections in 2018, siding with environmental groups that said delisting wasn’t based on sound science. Those groups want protections kept in place so bears can continue moving into new areas.

“We should not be ready to trust those states,” said attorney Andrea Zaccardi, of the Center for Biological Diversity.

U.S. government scientists have said the region’s grizzlies are biologically recovered but in 2021 decided that protections were still needed because of human-caused bear deaths and other pressures. Bears considered problematic are regularly killed by wildlife officials.

A decision on the states’ petitions was long overdue. Idaho Gov. Brad Little on Thursday had filed notice he intended to sue over the delay. Idaho’s petition was broader than the ones filed by Montana and sought to lift protections nationwide.

That would have included small populations of bears in portions of Idaho, Montana and Washington state, where biologists say the animals have not yet recovered to sustainable levels. It also could have prevented the return of bears to other areas such as the North Cascades region.

Australia’s drugs watchdog on Friday announced that psychedelic substances MDMA and psilocybin — more commonly known as ecstasy and magic mushrooms — will soon be used in the treatment of depression and post-traumatic stress.

Psychiatrists will be able to prescribe the two substances from July, the Therapeutic Goods Administration said after finding “sufficient evidence for potential benefits in certain patients.”

The two drugs are currently “prohibited substances” and can only be used in closely controlled clinical trials.

The administration said they had been found to be “relatively safe” when administered in a medical setting and provided an “altered state of consciousness” that could help patients.

Mike Musker, a mental health and suicide prevention researcher at the University of South Australia, welcomed the move as “long-awaited.”

“There are many people in the community experiencing PTSD (post-traumatic stress disorder) and depression, particularly army veterans and people who have worked in emergency services, where standard psychiatric drugs have not worked and offer no relief,” he said.

Musker said the two drugs “reduce inhibitions” and could help people process difficult images and memories.

For now, the use of MDMA and psilocybin will be limited to the treatment of depression and post-traumatic stress.

But advocates hope to one day use them for alcohol dependence, obsessive compulsive disorder and eating disorders.

Psychedelics have been used by Indigenous peoples for millennia, but Western researchers only started seriously looking into their potential uses in the middle of the last century.

The drugs became symbols of the counterculture movement of the 1960s and were banned.

Authorities in Canada and the United States are among those who have already permitted the medical use of MDMA and psilocybin.

At a nuclear waste site in Normandy, robotic arms guided by technicians behind a protective shield maneuver a pipe that will turn radioactive chemicals into glass as France seeks to make safe the byproducts of its growing reliance on atomic power.

The fuel-cooling pools in La Hague, on the country’s northwestern tip, could be full by the end of the decade and state-owned Orano, which runs them, says the government needs to outline a long-term strategy to modernize its aging facilities no later than 2025.

While more nuclear energy can help France and other countries to reduce planet-warming emissions, environmental campaigners say it replaces one problem with another.

To seek solutions, President Emmanuel Macron, who has announced plans to build at least six new reactors by 2050, on Friday chairs the first of a series of meetings on nuclear policy that will discuss investments and waste recycling.

“We can’t have a responsible nuclear policy without taking into account the handling of used fuel and waste. It’s a subject we can’t sweep under the rug,” a government adviser told Reuters, speaking on condition of anonymity.

“We have real skills and a real technological advantage, especially over the United States. Russia is the only other country that is able to do what France does in terms of treatment and recycling.”

La Hague is the country’s sole site able to process and partially recycle used nuclear fuel.

France historically has relied on nuclear power for around 70% of its energy, although the share is likely to have fallen last year as the nuclear fleet suffered repeated outages.

Since the launch of the site at La Hague in 1976, it has treated nearly 40,000 tons of radioactive material and recycled some into nuclear fuel that can be reused. The waste that cannot be recycled is mixed with hardening slices of glass and buried for short-term storage underground.

But its four existing cooling pools for spent fuel rods and recycled fuel that has been reused risk saturation by 2030, according to French power giant EDF, which runs France’s 56-strong fleet of reactors, the world’s second biggest after the United States.

Should saturation happen, France’s reactors would have nowhere to place their spent fuel and would have to shut down — a worst-case scenario that led France’s Court of Audit to designate La Hague as “an important vulnerability point” in 2019.

Cool pools and deep clay

EDF is hurrying to build an extra refrigerated pool at La Hague, at a cost of $1.37 billion, to store spent nuclear fuel — a first step before the waste can be treated — but that will not be ready until 2034 at the earliest.

Meanwhile, France’s national agency for managing nuclear waste last month requested approval for a project to store permanently high-level radioactive waste.

The plan, called Cigéo, would involve placing the waste 500 meters below ground in a clay formation in eastern France.

Construction is expected in 2027 if it gets approval. Among those opposed to it are residents of the nearby village of Bure and anti-nuclear campaigners.

Jean-Christophe Varin, deputy director of the La Hague site, told Reuters Orano could be flexible to ensure more recycling is done at the facility and there were “several possible scenarios.”

However, he said they could not be worked on in detail in the absence of a strategic vision. Orano, for which EDF accounts for 95% of its recycling business, says it needs clear direction from the government no later than 2025, to give it time to plan the necessary investments.

The costs are likely to be high. Just keeping up with current operations at La Hague costs nearly $330 million a year.

Options EDF and Orano are considering include finding a way to recycle the used fuel more than once, but critics say the recycling itself creates more radioactive waste and is not a long-term solution. For now, the backup plan is to fit more fuel containers into the existing pools.

After being cooled in a pool for about seven years, used nuclear fuel is separated into non-recyclable leftovers that are turned into glass (4% of the material), plutonium (1%) to create a new nuclear fuel called MOX, on which around 40% of France’s reactors can run, and reprocessed uranium (95%).

The uranium in the past was sent to Russia for reenrichment and return for use in some EDF reactors, but EDF stopped doing that in 2013 as it was too costly.

In spite of the war in Ukraine, which has made many in the West avoid doing business with Russia, EDF is expected to resume sending uranium to Russia this year as the only country able to process it. It declined to confirm to Reuters it would do so.

The facility at La Hague, with its 1980s-era buildings and Star Wars-style control rooms, has its limitations.

“If we had to process MOX fuel in large quantities, the facility today isn’t adapted for it,” Varin said. “For multicycle recycling, the technology is not the same, so the modernization or replacement of installations” would require “significant” investments, he said.

U.S. health officials said Thursday a company is recalling its over-the-counter eye drops that have been linked to an outbreak of drug-resistant infections.

The Centers for Disease Control and Prevention this week sent a health alert to doctors, saying the outbreak included at least 55 people in 12 states. One died and at least five others had permanent vision loss.

The infections, including some found in blood, urine and lungs, were linked to EzriCare Artificial Tears. Many said they had used the product, which is a lubricant used to treat irritation and dryness.

The eye drops are sold under the name EzriCare and are made in India by Global Pharma Healthcare. The Food and Drug Administration said the company recalled unexpired lots of EzriCare Artificial Tears and another product, Delsam Pharma’s Artificial Tears.

The FDA recommended the recall based on manufacturing problems including lack of testing and proper controls on packaging. The agency also blocked import into the United States.

The infections were caused by a bacteria called Pseudomonas aeruginosa. Investigators detected it in open EzriCare bottles, but further testing was underway.

EzriCare, the company that markets the eye drops in the U.S., said it is not aware of any evidence definitively linking the outbreak to the product, but that it has stopped distributing the eye drops. It also has a notice on its website urging consumers to stop using the product.

Infections were diagnosed in patients in California, Colorado, Connecticut, Florida, New Jersey, New Mexico, New York, Nevada, Texas, Utah, Washington and Wisconsin. A person in Washington died with a blood infection.

The outbreak is considered particularly worrisome because the bacteria driving it are resistant to standard antibiotics.

Investigators found the bacteria were not susceptible to any antibiotics routinely tested at public health laboratories. However, a newer antibiotic named cefiderocol seemed to work.

How could eye drops cause infections in the blood or lungs? The eye connects to the nasal cavity through the tear ducts. Bacteria can move from the nasal cavity into the lungs. Also, bacteria in these parts of the body can seed infections at other sites such as in the blood or wounds, CDC officials said.

A legendary U.S. groundhog, from the (east central U.S.) town of Punxsutawney, Pennsylvania, was pulled from his burrow early Thursday, with local officials declaring he saw his shadow, indicating, according to legend, there will be at least six more weeks of winter.

The annual observance of Groundhog Day on February 2 brings thousands of revelers to the town—located about 105 kilometers northeast of Pittsburgh—each year. Local officials, dressed in top hats and long coats, make a show of pulling the famous groundhog Punxsutawney Phil from his underground burrow to get his forecast.

The event is held shortly after dawn, around 7:15am, but the festivities begin as early as early as 3:30am with live entertainment and fireworks.

According to the organizer’s website, the tradition of seeking a weather forecast from a groundhog—a large rodent and member of the squirrel family—began in the town in 1886. Its origins go back to both Christian and pagan observances in Europe.

The pagan ritual marked the halfway point between the winter solstice and spring equinox. In Christian tradition, the feast day of Candlemas was when the church would distribute candles needed for the rest of winter, and it evolved into a prediction for how much longer winter would last.

Historians say the Germans began the tradition of involving an animal to the prediction process, using a hedgehog, a small, spiny animal common in parts of Europe. Germans immigrating to the eastern United States, where there are no hedgehogs, kept up the tradition by turning to groundhogs.

While the tradition and the celebration that accompanies it has stood the test of time, the groundhog has not had a good track record of accurately predicting winter weather. The U.S. National Oceanic and Atmospheric Administration (NOAA), reports Punxsutawney Phil has been right roughly 40% of the time over the last 10 years.

Some information for this report was provided by the Associated Press.

Personal possession of a small amount of hard drugs is now legal in the Canadian province of British Columbia. The controversial move is intended to reduce deaths from drug use.

The personal possession of 2.5 grams of hard drugs, including cocaine, crack cocaine, heroin, fentanyl, methamphetamine and morphine, has now been decriminalized. This temporary exemption means a person found with a small quantity of these drugs will not have them seized nor face arrest or any criminal charges. 

An average of six people a day die in British Columbia from illicit drug use, mostly men in their private residences. 

The day the three-year pilot program went into effect, the provincial coroner announced 2,272 people had died in 2022 from drug overdose. That was the second highest on record, topped only by 2,306 deaths in 2021. 

It is hoped decriminalizing small-scale possession will help fight drug mortality by putting the focus on treatment instead of criminal prosecution. 

Retired police officer Chuck Doucette, president of the Drug Prevention Network of Canada, is strongly opposed to the move, and said that “it really doesn’t address the issues at all, it’s not going to save any lives.” 

He pointed to the number of deaths by overdose and added that with drugs, “Whether they’re legal or decriminalized or not — doesn’t make them any less likely to kill you.” 

Kora DeBeck, a research scientist at the BC Center on Substance Use in Vancouver and an associate professor in the School of Public Policy at Simon Fraser University, backs decriminalization. She said that research shows prohibition does not work, but compassionate treatment of drug-dependent people can work. 

“We see so many signals that that improves our ability to connect with people who use drugs — to connect them with supports and services and things to reduce harm to them, and to their community,” DeBeck said.  

She added that decriminalization had already happened to a large extent nationwide, with the Royal Canadian Mounted Police and other law enforcement agencies already not arresting anyone found with a small amount of narcotics. 

Constable Tania Visintin of the Vancouver Police Department says the difference now is that any small amount drugs found will not be seized. 

“We were legally bound to seize those drugs, even if it was a small amount, and we would seize them for destruction. So they would never be part of any kind of charge or court case at all,” Visintin said. “But now under this new exemption, then, we just won’t be seizing any drugs that we find that are in a small personal use possession type of form.” 

For DeBeck, the benefit of this is that those addicted to drugs won’t be compelled to go to extraordinary lengths to replenish their supply. Before, said DeBeck, if their drugs were seized, “they may go to a less reliable source.”

DeBeck said that it placed people “in a desperate situation, they may have to resort to risky income generation or criminal activity or something like that.” 

The exemption, which has the blessing of the government of Prime Minister Justin Trudeau, will last for three years and is limited to British Columbia for now.

For thousands of years, ancient Egyptians mummified their dead in the search for eternal life. Now, researchers have used chemistry and an unusual collection of jars to figure out how they did it.

Their study, published Wednesday in the journal Nature, is based on a rare archaeological find: An embalming workshop with a trove of pottery around 2,500 years old. Many jars from the site were still inscribed with instructions like “to wash” or “to put on his head.”

By matching the writing on the outside of the vessels with the chemical traces inside, researchers uncovered new details about the “recipes” that helped preserve bodies for thousands of years.

“It’s like a time machine, really,” said Joann Fletcher, an archaeologist at University of York who was not involved with the study. “It’s allowed us to not quite see over the shoulders of the ancient embalmers, but probably as close as we’ll ever get.”

Those recipes showed that embalmers had deep knowledge about what substances would help preserve their dead, said Fletcher, whose partner was a co-author on the study. And they included materials from far-flung parts of the world — meaning Egyptians went to great lengths to make their mummies “as perfect as they could possibly be.”

The workshop — uncovered in 2016 by study author Ramadan Hussein, who passed away last year — is located in the famous burial grounds of Saqqara. Parts of it sit above the surface, but a shaft stretches down to an embalming room and burial chamber underground, where the jars were discovered.

It was in rooms like these where the last phase of the process took place, said Salima Ikram, an Egyptologist at The American University in Cairo who was not involved with the study. After drying out the body with salts, which probably took place above ground, embalmers would then take the bodies below.

“This was the last phase of your transformation where the secret rites, the religious rites, were being performed,” Ikram said. “People would be chanting spells and hymns while you were being wrapped and resin was being anointed all over your body.”

Experts already had some clues about what substances were used in those final steps, mainly from testing individual mummies and looking at written texts. But a lot of gaps remained, said senior author Philipp Stockhammer, an archaeologist at Ludwig Maximilian University in Germany.

The new finds helped crack the case.

Take the word “antiu,” which shows up in a lot of Egyptian texts but didn’t have a direct translation, Stockhammer said. In the new study, scientists found that several jars labeled as “antiu” contained a mixture of different substances — including animal fat, cedar oil and juniper resin.

These substances, along with others found in the jars, have key properties that would help preserve the mummies, said lead author Maxime Rageot, an archaeologist at Germany’s University of Tubingen.

Plant oils — which were used to protect the liver and treat the bandages — could ward off bacteria and fungi, while also improving the smell. Hard materials like beeswax, used on the stomach and skin, could help keep out water and seal the pores.

Some of the substances came from very far away — like dammar and elemi, types of resin that come from the tropical rainforests of Southeast Asia. These results show that ancient Egyptians would trade far and wide to get the most effective materials, the authors said.

“It’s interesting to see the complexity,” Stockhammer said. “Having this global network on the one hand, having all this chemical knowledge on the other side.”

Ikram said an important next step for the research will be to test different parts of actual mummies to see if the same substances show up. And these recipes probably weren’t universal — they changed over time and varied between workshops.

Still, the study gives a basis for understanding the past, and can bring us closer to people who lived long ago, she said.

Australian authorities on Wednesday found a radioactive capsule smaller than a coin that was lost in the vast Outback after nearly a week-long search along a 1,400 kilometers (870 miles) stretch of highway, officials said. 

The Caesium-137 capsule was discovered when a vehicle travelling at 70 kms per hour equipped with specialist detection equipment picked up the radiation, according to officials from the state of Western Australia. 

The search team then used portable detection equipment to find the capsule, which was located about 2 meters from the side of the road, they added. 

“I do want to emphasize this is an extraordinary result,” Western Australia’s Emergency Services Minister Stephen Dawson said in a news conference. 

“When you consider the scope of the research area, locating this object was a monumental challenge, the search groups have quite literally found the needle in the haystack,” Dawson said. 

The military was verifying the capsule and it would be taken to a secure facility in the city of Perth on Thursday, he added. Officials from Western Australia’s emergency response department, defense authorities, radiation specialists and others have been combing a stretch of highway for the tiny capsule that was lost in transit more than two weeks ago. 

The radioactive capsule was part of a gauge used to measure the density of iron ore feed from Rio Tinto’s Gudai-Darri mine in the state’s remote Kimberley region. The ore was being taken to a facility in the suburbs of Perth – a distance longer than the length of Great Britain. 

Officials said the capsule apparently fell off a truck and landed on the side of the road, adding that it was unlikely there will be contamination in the area. 

The silver capsule, 6 mm in diameter and 8 mm long, contains Caesium-137 which emits radiation equal to 10 X-rays per hour. People had been told to stay at least five meters (16.5 feet) away from the capsule if they spotted it, because exposure could cause radiation burns or radiation sickness. However, driving past it was believed to be relatively low risk, akin to taking an X-ray. 

Western Australia’s Chief Health Officer Andrew Robertson said the capsule was found in a remote area far from any community and it was unlikely anyone had been exposed to radiation. 

He said there would be an investigation and prosecutions would be considered under state radiation safety laws from 1975. The maximum penalty for failing to safely handle radioactive substances is $780 and $35 per day the offence continues, though the state government said on Wednesday it was considering a change to laws to allow for bigger penalties.

The dodo bird isn’t coming back anytime soon. Nor is the woolly mammoth. But a company working on technologies to bring back extinct species has attracted more investors, while other scientists are skeptical such feats are possible or a good idea. 

Colossal Biosciences first announced its ambitious plan to revive the woolly mammoth two years ago, and on Tuesday said it wanted to bring back the dodo bird, too. 

“The dodo is a symbol of man-made extinction,” said Ben Lamm, a serial entrepreneur and co-founder and CEO of Colossal. The company has formed a division to focus on bird-related genetic technologies. 

The last dodo, a flightless bird about the size of a turkey, was killed in 1681 on the island of Mauritius in the Indian Ocean. 

The Dallas company, which launched in 2021, also announced Tuesday it had raised an additional $150 million in funding. To date, it has raised $225 million from wide-ranging investors that include United States Innovative Technology Fund, Breyer Capital and In-Q-Tel, the CIA’s venture capital firm that invests in technology. 

The prospect of bringing back the dodo isn’t expected to directly make money, Lamm said. But the genetic tools and equipment that the company develops to try to do it may have other uses, including for human health care, he said. 

For example, Colossal is now testing tools to tweak several parts of the genome simultaneously. It’s also working on technologies for what is sometimes called an “artificial womb,” he said. 

The dodo’s closest living relative is the Nicobar pigeon, said Beth Shapiro, a molecular biologist on Colossal’s scientific advisory board, who has been studying the dodo for two decades. Shapiro is paid by the Howard Hughes Medical Institute, which also supports The Associated Press’ Health and Science Department. 

Her team plans to study DNA differences between the Nicobar pigeon and the dodo to understand “what are the genes that really make a dodo a dodo,” she said. 

The team may then attempt to edit Nicobar pigeon cells to make them resemble dodo cells. It may be possible to put the tweaked cells into developing eggs of other birds, such as pigeons or chickens, to create offspring that may in turn naturally produce dodo eggs, Shapiro said. The concept is still in an early theoretical stage for dodos. 

Because animals are a product of both their genetics and their environment — which has changed dramatically since the 1600s — Shapiro said that “it’s not possible to recreate a 100% identical copy of something that’s gone.” 

Other scientists wonder if it’s even advisable to try, and question whether “de-extinction” diverts attention and money away from efforts to save species still on Earth. 

“There’s a real hazard in saying that if we destroy nature, we can just put it back together again — because we can’t,” said Duke University ecologist Stuart Pimm, who has no connection to Colossal. 

“And where on Earth would you put a woolly mammoth, other than in a cage?” asked Pimm, who noted that the ecosystems where mammoths lived disappeared long ago.
