LONDON — Scientists searching for the origins of COVID-19 have zeroed in on a short list of animals that possibly helped spread it to people, an effort they hope could allow them to trace the outbreak back to its source.

Researchers analyzed genetic material gathered from the Chinese market where the first outbreak was detected and found that the most likely animals were raccoon dogs, civet cats and bamboo rats. The scientists suspect infected animals were first brought to the Wuhan market in late November 2019, which then triggered the pandemic.

Michael Worobey, one of the new study’s authors, said they found which sub-populations of animals might have transmitted the coronavirus to humans. That may help researchers pinpoint where the virus commonly circulates in animals, known as its natural reservoir.

“For example, with the raccoon dogs, we can show that the raccoon dogs that were [at the market] … were from a sub-species that circulates more in southern parts of China,” said Worobey, an evolutionary biologist at the University of Arizona. Knowing that might help researchers understand where those animals came from and where they were sold. Scientists might then start sampling bats in the area, which are known to be the natural reservoirs of related coronaviruses like SARS.

While the research bolsters the case that COVID-19 emerged from animals, it does not resolve the polarized and political debate over whether the virus instead emerged from a research lab in China.

Mark Woolhouse, a professor of infectious diseases at the University of Edinburgh, said the new genetic analysis suggested that the pandemic “had its evolutionary roots in the market” and that it was very unlikely COVID-19 was infecting people before it was identified at the Huanan market.

“It’s a significant finding and this does shift the dial more in favor of an animal origin,” said Woolhouse, who was not connected to the research. “But it is not conclusive.”

An expert group led by the World Health Organization concluded in 2021 that the virus probably spread to humans from animals and that a lab leak was “extremely unlikely.” WHO chief Tedros Adhanom Ghebreyesus later said it was premature to rule out a lab leak.

An AP investigation in April found the search for the COVID origins in China has gone dark after political infighting and missed opportunities by local and global health officials to narrow the possibilities.

Scientists say they may never know for sure where exactly the virus came from.

In the new study, published Thursday in the journal Cell, scientists from Europe, the U.S. and Australia analyzed data previously released by experts at the Chinese Center for Disease Control and Prevention. It included 800 samples of genetic material Chinese workers collected on Jan. 1, 2020, from the Huanan seafood market, the day after Wuhan municipal authorities first raised the alarm about an unknown respiratory virus.

Chinese scientists published the genetic sequences they found last year, but did not identify any of the animals possibly infected with the coronavirus. In the new analysis, researchers used a technique that can identify specific organisms from any mixture of genetic material collected in the environment.

Worobey said the information provides “a snapshot of what was [at the market] before the pandemic began” and that genetic analyses like theirs “helps to fill in the blanks of how the virus might have first started spreading.”

Woolhouse said the new study, while significant, left some critical issues unanswered.

“There is no question COVID was circulating at that market, which was full of animals,” he said. “The question that still remains is how it got there in the first place.”

CHONBURI, Thailand — Only a month after Thailand’s adorable baby hippo Moo Deng was unveiled on Facebook, her fame became unstoppable both domestically and internationally.

Zookeeper Atthapon Nundee has been posting cute moments of the animals in his care for about five years. He never imagined Khao Kheow Open Zoo’s newborn pygmy hippo would become an internet megastar within weeks.

Cars started lining up outside the zoo well before it opened Thursday. Visitors traveled from near and far for a chance to see the pudgy, expressive 2-month-old in person at the zoo about 100 kilometers southeast of Bangkok. The pit where Moo Deng lives with her mom, Jona, was packed almost immediately, with people cooing and cheering every time the pink-cheeked baby animal made skittish movements.

“It was beyond expectation,” Atthapon told The Associated Press. “I wanted people to know her. I wanted a lot of people to visit her, or watch her online, or leave fun comments. I never would’ve thought (of this).”

Moo Deng, which literally means “bouncy pork” in Thai, is a type of meatball. The name was chosen by fans via a poll on social media, and it matches her other siblings: Moo Toon (stewed pork) and Moo Waan (sweet pork). There is also a common hippo at the zoo named Kha Moo (stewed pork leg).

“She’s such a little lump. I want to ball her up and swallow her whole!” said Moo Deng fan Areeya Sripanya while visiting the zoo Thursday.

Already, Moo Deng has been made into memes. Artists are drawing cartoons based on her. Social media platform X even featured her in its official account’s post.

With all that fame, zoo director Narongwit Chodchoi said they have begun patenting and trademarking “Moo Deng the hippo” to prevent the animal from being commercialized by anyone else. “After we do this, we will have more income to support activities that will make the animals’ lives better,” he said.

“The benefits we get will return to the zoo to improve the life of all animals here.”

The zoo sits on 800 hectares of land and is home to more than 2,000 animals. It runs breeder programs for many endangered species like Moo Deng’s. The pygmy hippopotamus that’s native to West Africa is threatened by poaching and loss of habitat. There are only 2,000-3,000 of them left in the wild.

To help fund the initiative, the zoo is making Moo Deng shirts and pants that will be ready for sale at the end of the month, with more merchandise to come.

Narongwit believes a factor of Moo Deng’s fame is her name, which compliments her energetic and chaotic personality captured in Atthapon’s creative captions and video clips.

Appropriately, Moo Deng likes to “deng,” or bounce, and Atthapon got a lot of cute and funny moments of her giddy bouncing on social media. Even when she’s not bouncing, the hippo is endlessly cute — squirming as Atthapon tries to wash her, biting him while he was trying to play with her, calmly closing her eyes as he rubs her pinkish cheeks or her chubby belly.

Atthapon, who has worked at the zoo for eight years taking care of hippos, sloths, capybaras and binturongs, said baby hippos are usually more playful and energetic, and they become calmer as they get older.

The zoo saw a spike in visitors since Moo Deng’s fame — so much that the zoo now has to limit public access to the baby’s enclosure to five-minute windows throughout the day during weekends.

Narongwit said the zoo has been receiving over 4,000 visitors during a weekday, up from around just 800 people, and more than 10,000 during a weekend, up from around 3,000 people.

But the fame has also brought some hostile visitors to Moo Deng, who only wakes up ready to play about two hours a day. Some videos showed visitors splashing water or throwing things at the sleeping Moo Deng to try to wake her up. The hippo pit now has a warning sign against throwing things at Moo Deng — posted prominently at the front in Thai, English and Chinese.

Narongwit said the zoo would take action under the animal protection law if people mistreat the animal. But clips emerged of people treating Moo Deng poorly, and the backlash was fierce. The zoo director said that since then, they haven’t seen anyone doing it again.

For fans who can’t make the journey or are discouraged after seeing the crowds for Moo Deng, the Khao Kheow Open Zoo set up cameras and plan to start a 24-hour live feed of the baby hippo in the coming week.

Addis Ababa, Ethiopia — One of the hurdles to improving health care systems for African countries is the shortage of scientists and lack of meaningful medical research on the continent, experts say.

An organization hopes to change that by enabling researchers and policymakers in three large African countries to develop more extensive and relevant research.

According to a 2017 report by the World Economic Forum, Africa is home to 15% of the world’s population and 25% of the world’s disease burden — but produces just 2% of the world’s medical research.

The report said of the medical research that does occur, much of it fails to prioritize diseases or health problems most pressing for Africans.

A group of African health researchers and institutions are now pushing for the continent’s medical research to be more focused on the continent’s own medical problems.

The African Population and Health Research Center is bringing together scientists, academics, policymakers and government officials from Ethiopia, Kenya and Nigeria.

Their goal is to strengthen African leadership in research and development, ensuring that the findings from these researchers are relevant and accessible to decision-makers, leading to better health care systems across the continent.

Catherine Kyobutungi, head of the organization, said African-led research can help solve health problems on the continent much more easily and quickly.

“If we want the research to be done by Africans in Africa on African issues, that is [how] the priorities for what research should be done are defined, not just by academics, but by the people who are going to use that research for decision-making,” she said.

“What we are trying to achieve is to shift what research is and what it is for and to create an army of African scientists that do research to solve African problems in real time, not after 50 years,” Kyobutungi said.

Dr. Hadiza Galadanci, a professor of obstetrics and gynecology at Bayero University in Nigeria, said her country accounts for about 28% of maternal deaths worldwide each year.

She and researchers from four African countries, Birmingham University in the United Kingdom and the World Health Organization published research on the best way to save women who were dying from postpartum hemorrhage, or excessive bleeding after childbirth. Their innovation — a calibrated obstetric drape, which is placed beneath a birthing mother — allows physicians to collect and precisely measure blood and fluid loss.

“The drape is just put under … the woman when she’s going to deliver. And then, as soon as she delivers, any blood that comes out goes to the drape. So, we have an objective assessment,” Galadanci explained, saying that the process allows for more specific treatment.

“When we did this, we found out that we could reduce the rate of severe [postpartum hemorrhage] leading to maternal death by 60%.”

African researchers face challenges ranging from a lack of reliable data and funding to poor infrastructure to cultural and religious issues.

With the support of the Bill and Melinda Gates Foundation, Africa Research Connect was developed to connect and enhance the visibility of scientists, institutions, policymakers and donors.

Jude Igumbor, an associate professor at Wits School of Public Health in South Africa, wants to improve the visibility of African scientists and their work.

“What we give African scientists is they are able to find each other for collaboration,” he said.

The African Population and Health Research Center is calling on donors to fund African institutions and researchers directly instead of going through other organizations, saying that doing so helps the money create opportunities and hone the skills of researchers on the continent.

Washington — When activists, policymakers and representatives from across the globe gather next week in New York to participate in climate week, one pressing issue on the agenda that is less frequently discussed and known will be the environmental impact of seabed mining.

As countries look for ways to lower emissions, critical minerals are playing a key role in that transition. Critical minerals are used in all kinds of green technologies, from solar panels and wind turbines to batteries in electric vehicles. And one place where those mineral resources are abundant is deep under the sea.

The debate over accessing seabed resources is heated. Supporters say the technology exists to safely access these critical minerals undersea, but environmentalists and activists say the potential of undiscovered biodiversity on the seafloor is too important to endanger.

During climate week, which will take place on the sidelines of U.N. General Assembly meetings, organizers are expected to host a roundtable on the environmental impact of seabed mining and other discussions about critical minerals.

The World Economic Forum says that if the globe wants to reach net-zero emissions by 2050, two-thirds of vehicles must be powered by electric batteries. And the International Energy Agency says that to reach that goal, the world needs six times more mineral resources by 2040 than it has today.

Some of the largest mineral deposits are found on the ocean floor in the form of polymetallic nodules, or rocks.

Ocean of resources

According to the International Seabed Authority, or ISA, there are 21 billion tons of polymetallic nodules strewn across the seabed of the Clarion-Clipperton Zone, or CCZ. Each nodule contains a combination of electric vehicle battery components such as nickel, manganese, copper and cobalt. The ISA plans to release regulations for mining in the international waters of the CCZ by 2025.

The ISA has already awarded 17 exploration contracts for polymetallic nodules in the Clarion-Clipperton Zone – a large swath of the Pacific Ocean the size of the continental United States which sits between Hawaii and Mexico. Three of those exploration contracts went to The Metals Company, a Canadian deep-sea mining company.

The Pacific Island Nations of Nauru, Kiribati and Tonga have sponsored The Metals Company’s efforts to develop a portion of the seabed. In an interview with VOA, CEO Gerard Barron said the company is ready to begin as soon as the ISA allows mining.

“Our collector methodology is to put a robot on the seafloor which crawls around the ocean floor and fires a jet of water at the nodule and it creates an inverse pressure and lifts the nodule up, and so we don’t go down and scour the seafloor,” said Barron via Zoom, adding that TMC has spent the past decade focused on testing this equipment and collecting data on its environmental impact as part of its permit application to the ISA.

Moratorium needed

Critics worry scooping up these mineral-rich rocks will disrupt important biodiversity – much of it still unnamed and some of it undiscovered. Researchers have found that 90% of the more than 5,000 species in the zone are new to science. Eddie Palu, president of the Tonga Fishery Association, wants a pause for more research.

“We demand a moratorium on the seabed mining until the environmental, economic and social risk are comprehensively understood,” he said during a panel discussion at the recent Pacific Islands Forum in Tonga.

Shiva Gounden from Greenpeace Australia Pacific, who also sat on the panel, agreed.

“We know only very little of the deep sea, and the race for the final frontier could cause irreversible damages to the people and to the communities of our Pacific,” Gounden said.

But scientists say no light and very little oxygen reaches the deep sea – limiting the life there to mostly bacteria and small invertebrates.

The Metals Company’s Barron said combating climate change is a bigger threat to the planet than undersea mining, adding that the company’s environmental impact studies show that “we can safely collect these nodules” and turn them into battery metals without having “a negative impact on the ocean.”

“The notion that we can do any extraction with zero impact is a dream,” added Barron. “The oceans are impacted by every single thing we do today, especially global warming. So, we need to address the main driver for climate change and reduce emissions.”

Fueling innovation

Still, the quest to do just that – access minerals on the seabed with minimal impact to the environment – has created competition between technology companies.

U.S. tech startup Impossible Metals is testing a robot which can avoid nodules where it detects life and harvests those where it does not.

“The vehicle hovers above the seabed, uses the camera and it actually picks up the nodules one by one. So this really minimizes all of the negative concerns around big sediment plumes,” CEO Oliver Gunasekra told VOA in an interview.

Gunaskera’s company spun off Viridian Biometals. Its technology bypasses energy-intensive processes such as smelting with bacteria which can separate metal ore from the rock around it. The process creates no emissions or waste.

“The bacteria need oxygen just like we do to breathe. And when there’s not enough oxygen in the water around them, the bacteria have learned that there’s oxygen in the rocks, and they have adapted to breathe that oxygen,” said Viridian CEO Eric Macris.

Impossible Metals and Viridian Biometals say they are two to three years out from commercializing their technology, depending on funding. TMC says it could be ready to begin its collection operations as soon as international regulations are released next year.

new york — Get ready for a partial lunar eclipse and supermoon, all rolled into one. 

The spectacle will be visible in clear skies across North America and South America Tuesday night and in Africa and Europe Wednesday morning. 

A partial lunar eclipse happens when the Earth passes between the sun and moon, casting a shadow that darkens a sliver of the moon and appears to take a bite out of it. 

Since the moon will inch closer to Earth than usual, it’ll appear a bit larger in the sky. The supermoon is one of three remaining this year. 

“A little bit of the sun’s light is being blocked so the moon will be slightly dimmer,” said Valerie Rapson, an astronomer at the State University of New York at Oneonta. 

The Earth, moon and sun line up to produce a solar or lunar eclipse anywhere from four to seven times a year, according to NASA. This lunar eclipse is the second and final of the year after a slight darkening in March. 

In April, a total solar eclipse plunged select cities into darkness across North America. 

No special eye protection is needed to view a lunar eclipse. Viewers can stare at the moon with the naked eye or opt for binoculars and telescopes to get a closer look. 

To spot the moon’s subtle shrinkage over time, hang outside for a few hours or take multiple peeks over the course of the evening, said KaChun Yu, curator at the Denver Museum of Nature and Science. 

“From one minute to the next, you might not see much happening,” said Yu. 

For a more striking lunar sight, skywatchers can set their calendars for March 13. The moon will be totally eclipsed by the Earth’s shadow and will be painted red by stray bits of sunlight filtering through Earth’s atmosphere.

Chinhoyi, Zimbabwe — Zimbabwe’s government has given in to pressure from rights groups and is now providing free treatment to women with obstetric fistula, a condition that makes it hard for mothers who went through difficult labor to control their bowels. For a closer look, VOA visited Chinhoyi, a farming and mining area about 150 kilometers west of Harare, where early marriages are common, and where the treatment is being offered.

Among the first beneficiaries of the treatment were young women at Chinhoyi Provincial Hospital after government gynecologists had performed surgery to address their cases of obstetric fistula. Twenty-three-year old Chiedza, not her real name as she requested that VOA protect her identity, was visibly happy as she had not been able to control her bowels since giving birth to her son seven years ago.

“When I gave birth I tore my private parts, so I couldn’t hold my feces,” she said. “It would just come out on its own. I would just feel something on my body flowing. I stayed like that because I did not have money to seek services of gynecologists to correct my condition. So, when I heard about this free service on a WhatsApp group for women, I called a toll-free number which was there and I came here. So I am now going to live a comfortable life. I can now perform even house chores comfortably.”

Another woman who asked to be called Tendai ruptured her bladder after protracted labor at home while giving birth at the age of 16.

“I would share nappies with my baby so as to block my smell from others,” she said. “At one time I almost committed suicide because people kept on laughing at my condition. I thought I had been bewitched till I came here and saw that there are some people in my condition. I am grateful for this procedure for it has given me hope.”

The World Health Organization estimates that between 50,000 and 100,000 women experience obstetric fistula every year and that about 2 million women in sub-Saharan Africa are living with the condition.  

Dr. Stanley Ngwaru, a senior gynecologist in Zimbabwe’s ministry of health, says the condition is an abnormal communication between the woman’s genital tract and the urinary tract or the rectum.

“They suffer shame and they suffer social segregation,” he said. “It’s very common in young women, because the genital tract is not well developed and when they go into labor, they are more likely to suffer from obstruction and this can lead to these communications are developing between the genital tract and the unit tract and the rectum.”

Lucia Masuka, head of Amnesty International in Zimbabwe, says she commends the government for offering the free service. However, she believes authorities needs to develop a strategy to help prevent this condition from afflicting young women in the first place.

“If we therefore facilitate access to sexual reproductive health services for this group, it will reduce instances of early pregnancies, and in turn, reduce cases of obstetrics fistula,” she said. “Whilst treatment is a positive development, it’s akin to trying to mop water from an open tap; you will never really be able to mop that water as long as the tap is open.”

Amnesty International in Zimbabwe last year pleaded with parliament to push the government to make obstetric fistula treatment a national issue after its research had revealed that the condition was rampant among young women in Zimbabwe and was not getting enough attention.

LONDON — Less than two months ahead of the COP29 United Nations Climate Summit, the Azerbaijani leadership laid out its plans on Tuesday for what it hoped to achieve, as countries continue to wrestle with how to raise ambitions for a new financing target.

The main task for the November summit is for countries to agree on a new annual target for funding that wealthy countries will pay to help poorer nations cope with climate change. Many developing countries say they cannot upgrade their targets to cut emissions faster without first receiving more financial support to invest in doing this.

With countries remaining far from agreement on the financing goal, the COP29 presidency this week outlined more than a dozen side initiatives that could raise ambitions, but do not require party negotiation and building consensus which can hamper progress. These take the form of new funds, pledges, and declarations that national governments can adopt.

Notably, this includes a fund with voluntary contributions from fossil fuel producing countries and companies for the public and private sectors working on climate issues, as well as grants that can be doled out to assist with climate-fueled natural disasters in developing countries.

Such side agendas use “the convening power of COP and the hosts’ respective national capabilities to form coalitions and drive progress,” said Mukhtar Babayev, who holds the rotating COP presidency, in a letter to all parties and stakeholders.

Over 120 countries pledged at last year’s COP28 summit in Dubai, for example, to triple renewable energy capacity by 2030.

The COP29 presidency also hopes to build support around a pledge to increase global energy storage capacity six times above 2022 levels, reaching 1,500 gigawatts by 2030. This would include a commitment to scale up investments in energy grids, adding or refurbishing more than 80 million km by 2040.

Babayev, who is Azerbaijan’s minister of ecology and natural resources, said the agenda would “help to enhance ambition by bringing stakeholders together around common principles and goals.”

“We hope to address some of the most pressing issues while also highlighting remaining priorities,” he said.

Another declaration would see countries and companies create a global market for clean hydrogen, addressing regulatory, technological, financing and standardization barriers.

COP29 leaders have also appealed for a “COP Truce” that would highlight the importance of peace and climate action.

Despite countries’ existing climate commitments, carbon dioxide emissions from burning fossil fuels hit a record high last year, and the world just registered its hottest summer on record as temperatures climb.

LONDON — Malnutrition is the world’s worst child health crisis and climate change will only make things more severe, according to Microsoft-co-founder turned philanthropist Bill Gates.

Between now and 2050, 40 million more children will have stunted growth and 28 million more will suffer from wasting, the most extreme and irreversible forms of malnutrition, as a result of climate change, the Bill & Melinda Gates Foundation said in a report on Tuesday.

“Unless you get the right food, broadly, both in utero and in your early years, you can never catch up,” Gates told Reuters in an online interview last week, referring to a child’s physical and mental capacity, both of which are held back by a lack of good nutrition. Children without enough of the right food are also more vulnerable to diseases like measles and malaria, and early death.

“Around 90% of the negative effect of climate change works through the food system. Where you have years where your crops basically fail because of drought or too much rain,” he said.

Gates was speaking ahead of the publication of the Bill and Melinda Gates Foundation’s annual Goalkeepers report, which tracks progress on the United Nations Sustainable Development Goals (SDGs), around reducing poverty and improving health. The report includes the projections above.

In 2023, the World Health Organization estimated that 148 million children experienced stunting and 45 million experienced wasting.

Gates called for more funding for nutrition, particularly through a new platform led by UNICEF aiming to co-ordinate donor financing, the Child Nutrition Fund, as well as more research. But he said the money should not be taken away from other proven initiatives, like routine childhood vaccinations, for this purpose.

“(Nutrition) was under-researched … it’s eye-opening how important this is,” he added, saying initiatives like food fortification or improving access to prenatal multi-vitamins could be as effective as some vaccines in improving child health in the world’s poorest countries.

The Gates Foundation said in January it plans to spend more on global health this year than ever before – $6.8 billion – as wider funding efforts stall.
