Blood banks in Cameroon are usually close to empty due to widely held taboos against blood donation. Officials in the central African country are trying to convince people to move past those beliefs amid an increased demand for blood and blood products in hospitals and on the front lines where soldiers are fighting separatists and Islamist militants. The effort comes ahead of World Blood Donor Day, observed on June 14. 

Illustrating the shortages is the story of a woman who told nurses at the Yaounde military hospital that she has not found anyone to donate blood to save the life of her two-year-old son. 

Hospital workers said the 34-year-old fruit seller’s blood was infected and that it could not be transfused to her son.

Medical staff members have requested blood from government hospitals to save the child’s life, the hospital said, adding that the blood bank at the military hospital is empty.

Celestin Ayangma, head of the laboratory that is in charge of the hospital’s blood bank, said that since January of this year, the Yaounde military hospital had been able to provide only six of the 20 units of blood it needs every day. Ayangma added that patients eventually die if they do not have relatives, friends or other donors to give the blood that the patients need.

By midday on Tuesday, the baby was still waiting for blood. 

Cameroon’s public health ministry reported that in 2022, hospitals in the country were able to collect a little more than 120,000 pints of blood from voluntary donors, family members and friends of sick patients. 

But each year, Cameroon needs at least 600,000 pints of blood for both private and government-owned hospitals.

The government says blood donation needs in Cameroon are increasing due to the separatist conflict in the country’s western regions and fighting with Boko Haram militants on the northern border with Nigeria. 

This year, government officials, health workers and aid agencies took to the streets ahead of World Blood Donor Day, trying to convince people to donate blood and save lives.

Ruth Abeng of the Cameroon Medical Council, an association of Cameroonian doctors, took part in the campaign. She sayid there are very few voluntary blood donors in Cameroon as some people are compelled to donate blood only when they see their sick relatives and friends in need of blood and dying. She said it is disheartening to see patients dying because some of their relatives believe that a blood donation is mystical.

Some Cameroonians believe that if they give blood, the recipient will receive any good luck and success they’ve had in life. Others say God will punish them if they donate blood to an evil person. 

The government says such beliefs are unfounded and people should not be afraid to donate blood. 

The Ministry of Health also says donated blood is not sold as some people erroneously believe. Blood that is donated is stored in banks and transfused to people in need, the government says. 

Hospitals say patients pay a fee of about $50 for the hospital to test donated blood and make sure it is safe to use. 

The government gives donors about $10 in a bid to encourage more donations. 

Cameroon says it expects to raise about 20,000 pints of blood by June 14. 

Hospitals say the amount will not be enough to meet the country’s needs but that it will reduce suffering and prevent some people from dying.

Singapore was the first country in the world to greenlight the sale of lab-grown meat, but even after nearly 2½ years, the fledgling industry is still struggling with supply issues and hurdles such as public acceptance, experts say.

Lab-grown or cultivated meat is meat grown in a lab by extracting cells from animals and growing the muscles to eventually have the texture, nutrition and taste of meat from real-life animals.

The product has long been touted as a potential solution to multiple issues, including burgeoning food insecurity brought by human-caused climate change, degrading soil and biodiversity, and a way to reduce greenhouse gas emissions from livestock.

Southeast Asia is at the forefront of the impact of climate change impacts, with recent heatwaves sweeping across the region and food security has become a priority in the region’s agenda. In land-scarce Singapore, the issue is even more acute where its citizens import 90% of the food they consume.

Turning to more sustainable meat is one of the city-state’s food strategies. Its so-called “30 by 30” goal aims to produce 30% of Singapore’s nutritional needs locally by 2030, and COVID-19’s impacts on food exports was another wake-up call for the country. Chicken rice is Singapore’s de-facto national dish, but its neighbor, Malaysia, banned its exports of chicken to Singapore last year due to a global feed shortage.

“We [Singapore] had to scramble to try and find chicken supplies from other countries,” Andre Huber, executive director of Huber’s Butchery and Bistro, the only restaurant in Singapore that serves cultivated chicken dishes, told VOA News.

“I think the government’s decision to try and grow some of our own produce … we don’t have land or animals roaming around. I think this [lab-grown chicken] can be grown in high rise buildings.”

Singapore gave its green light to the sale of lab-grown chicken in December 2020 but so far, the product from U.S. cultivated meat provider GOOD Meat is only available in Huber’s and remains in limited supply.

Asked why the supply of cultivated chicken remains limited after over two years of gaining approval, Jun Chong, GOOD Meat’s associate product developer said money has been an issue.

“It was after two years when we have enough fundings and investment of money, and then we started to build our own facility,” Chong said. “It’s slowly getting into place.”

The new facility Chong mentioned is set to become the largest cultivated meat production center in Asia when it opens later this year in Singapore’s Bedok town and will provide “tens of thousands of pounds of meat from cells,” according to a statement from GOOD Meat.

In addition to infrastructure, another controversy connected to cultivated meat is the use of fetal bovine serum, which is often made from killing cows when they are pregnant. A recent study showed that over 2 million bovine fetuses are used globally to produce around 800,000 liters of such serum, sparking ethical debates in the industry. The use of such serum also goes against the feature of lab-grown meat being slaughter-free.

Chong said GOOD Meat has just gained approval to use a new plant-based serum that will be able to replace the fetus bovine serum. He added that the firm will start using the new serum to grow the muscles of chicken meat after the Bedok facility starts operating.

Meanwhile, Alfredo Franco-Obregon, associate professor at the National University of Singapore, found a way to grow cell-based meat with a magnet that can potentially replace fetus bovine serum.

“We found that we are just as good as fetal bovine serum in sustaining muscle growth, which makes sense because these [meat] factors are coming from muscles, either from a fetus or in a dish,” he told VOA News in a video interview.

The muscle growth expert said if lab-grown meat can be scaled up, the inhumane livestock farms can hopefully be wiped out.

“You have to keep the animal alive for two years [before it’s ready to be made into meat], and it would be good if you could do it in a way that’s humane, but a lot of these systems aren’t very humane.”

Franco-Obregon added that while lab-grown meat cannot completely replace real meat, “there’s a way of improving … the livestock industry. It’s more efficient, less greenhouse emissions, higher productivity and cell-based meat will be a supplement. … We are going to run out of food. That’s the honest truth. And like it or not, we’re going to have to find alternatives, otherwise people will start to starve.”

Huang Dejian, deputy head of NUS’ Department of Food Science and Technology, echoed Franco-Obrego’s view. Huang pioneered extraction of plant-based cells to develop edible 3D-printed scaffolds to replace the current plastic scaffolds used in the production process.

“In a decade or two … maybe 50% of all the meat we found in our market is hybrid meat [lab-grown meat with animal cells and plant-based cells],” Huang told VOA.

Asked if lab-grown meat with many tech-heavy processes might involve more greenhouse gas emissions than traditional meat from livestock farms — as suggested by a preprint study at the University of California, Davis — Huang said, “I feel it’s unfair to calculate, you know, the footprint because it [the product] is too early. If you take advantage of technology to a level and the cost of production is lowered, it might also reduce the energy input and efficiency.”

Consumer acceptance of lab-grown meat could be a bigger challenge for the industry, he added, but he remained optimistic about the future of cultivated meat.

“A lot of the groundwork has already been laid. And we can see, I think in the next five years or so, people may be able to have a chance to taste [lab-grown meat]. The future to me is quite bright.”

U.N. Secretary-General Antonio Guterres said Monday that he will appoint a scientific advisory body in the coming days that will include outside experts on artificial intelligence, and said he is open to the idea of creating a new U.N. agency that would focus on AI.

“I would be favorable to the idea that we could have an artificial intelligence agency, I would say, inspired by what the International Atomic Energy Agency is today,” Guterres said of the U.N. nuclear watchdog agency.

He said he does not have the authority to create an IAEA-like agency — that is up to the organization’s 193-member states. But he said it has been discussed and he would see it as a positive development.

“What is the advantage of the IAEA — it is a very solid, knowledge-based institution,” Guterres told reporters. “And at the same time, even if limited, it has some regulatory functions. So, I believe this is a model that could be very interesting.”

The Vienna-based IAEA is the focal point for international nuclear cooperation. It has developed international nuclear safety standards and is both watchdog and advisor on the peaceful use of nuclear energy.

There are growing concerns about the power of artificial intelligence and how it can be abused for negative and even deadly purposes, including from Geoffrey Hinton, who is the scientist known as “the godfather of AI.”

British Prime Minister Rishi Sunak announced last week plans for the UK to host the first major global summit on AI safety in the autumn.

Guterres said in terms of regulating AI, in an industry where things move very quickly, you can establish a set of norms one day, and it can be outdated the next. So, something that is more flexible is necessary.

“We need a process, a constant process of intervention of the different stakeholders, working together to permanently establish a number of soft law mechanisms, a number of — I would say — norms, codes of conduct and others,” he said.

Guterres said the scientific advisory body he will soon create will also include the chief scientists from the U.N. Educational, Scientific and Cultural Organization (UNESCO) and the International Telecommunication Union (ITU), which is a specialized U.N. agency related to information and telecommunication technology.

He said outside experts, including two from the AI sphere, would be a part of the advisory body.

He also announced plans for a digital compact he says would be a voluntary “code of conduct” that he hopes technology companies and governments will adhere to, with the aim of decreasing the spread of mis- and dis-information and hate speech to billions of people and making the internet a safer space.

“Its proposals are aimed at creating guardrails to help governments come together around guidelines that promote facts, while exposing conspiracies and lies, and safeguarding freedom of expression and information,” he said. “And to help tech companies navigate difficult ethical and legal issues and build business models based on a healthy information ecosystem.”

He said tech companies have done little to prevent their platforms from contributing to hate and violence, and he criticized governments for ignoring human rights and sometimes taking drastic measures, including sweeping internet shutdowns.

Guterres said he hopes to issue the code of conduct after discussions with member states and before the U.N. Summit of the Future, which is planned for September 2024.

David Smith, a retired print technician from the north of England, was pursuing his hobby of looking for interesting shapes when he stumbled onto one unlike any other in November.  

When Smith shared his shape with the world in March, excited fans printed it onto T-shirts, sewed it into quilts, crafted cookie cutters or used it to replace the hexagons on a soccer ball — some even made plans for tattoos.

The 13-sided polygon, which 64-year-old Smith called “the hat,” is the first single shape ever found that can completely cover an infinitely large flat surface without ever repeating the same pattern.

That makes it the first “einstein” — named after the German for “one stone” (ein stein), not the famed physicist — and solves a problem posed 60 years ago that some mathematicians had thought impossible.

After stunning the mathematics world, Smith — a hobbyist with no training who told AFP that he wasn’t great at math in school — then did it again.

While all agreed “the hat” was the first einstein, its mirror image was required one in seven times to ensure that a pattern never repeated.

But in a preprint study published online late last month, Smith and the three mathematicians who helped him confirm the discovery revealed a new shape — “the specter.”

It requires no mirror image, making it an even purer einstein.

‘It can be that easy’  

Craig Kaplan, a computer scientist at Canada’s Waterloo University, told AFP that it was “an amusing and almost ridiculous story — but wonderful.”

He said that Smith, a retired print technician who lives in Yorkshire’s East Riding, emailed him “out of the blue” in November.

Smith had found something “which did not play by his normal expectations for how shapes behave,” Kaplan said.

If you slotted a bunch of these cardboard shapes together on a table, you could keep building outwards without them ever settling into a regular pattern.

Using computer programs, Kaplan and two other mathematicians showed that the shape continued to do this across an infinite plane, making it the first einstein, or “aperiodic monotile.”

When they published their first preprint in March, among those inspired was Yoshiaki Araki. The Japanese tiling enthusiast made art using the hat and another aperiodic shape created by the team called “the turtle,” sometimes using flipped versions.

Smith was inspired back and started playing around with ways to avoid needing to flip his hat.  

Less than a week after their first paper came out, Smith emailed Kaplan a new shape.

Kaplan refused to believe it at first. “There’s no way it can be that easy,” he said.

But analysis confirmed that Tile (1,1) was a “non-reflective einstein,” Kaplan said.

Something still bugged them — while this tile could go on forever without repeating a pattern, this required an “artificial prohibition” against using a flipped shape, he said.

So, they added little notches or curves to the edges, ensuring that only the non-flipped version could be used, creating “the spectre.”

‘Hatfest’

Kaplan said both their papers had been submitted to peer-reviewed journals. But the world of mathematics did not wait to express its astonishment.

Marjorie Senechal, a mathematician at Smith College in the United States, told AFP the discoveries were “exciting, surprising and amazing.”

She said she expects the spectre and its relatives “will lead to a deeper understanding of order in nature and the nature of order.”

Doris Schattschneider, a mathematician at Moravian College in the U.S., said both shapes were “stunning.”

Even Nobel-winning mathematician Roger Penrose, whose previous best effort had narrowed the number of aperiodic tiles down to two in the 1970s, had not been sure such a thing was possible, Schattschneider said.

Penrose, 91, will be among those celebrating the new shapes during the two-day “Hatfest” event at Oxford University next month.  

All involved expressed amazement that the breakthrough was achieved by someone without training in math.

“The answer fell out of the sky and into the hands of an amateur — and I mean that in the best possible way, a lover of the subject who explores it outside of professional practice,” Kaplan said.

“This is the kind of thing that ought not to happen, but very happily for the history of science does happen occasionally, where a flash brings us the answer all at once.”

Huge strides in life expectancy worldwide are bringing new challenges that come with increased longevity, the Dutch health minister told VOA this week.

“If you look at it from a global perspective, we’ve seen that over the past 25 years, on average we added more than five years of global life expectancy,” Ernst Kuipers, Dutch minister of health, welfare and sport, noted during a stop in Washington.

Looking at it another way, the former internist continued, “It actually means that for more than 20 years in a row, every week we added more than a day to the life expectancy of our world population. That is huge!”

Kuipers and a Dutch delegation co-led by the country’s minister of economy are in the U.S. to take part in a trade fair focused on international health and life sciences in Boston.

The Dutch are known to be the tallest people in the world and rank high in the world longevity list. Kuipers looked at the global picture when discussing the worldwide jump in life expectancy in the past quarter century.

While clean water supply, improved hygiene, sanitation conditions, access to vaccines, medicines and medical treatments have contributed to rising life expectancy in low-income countries, breakthroughs in many areas of life sciences have helped prolong life in higher-income countries, he pointed out.

“For example, new drugs in cancer treatment, newly developed interventions to treat cardiovascular diseases, and also improvement in public health.”

The good news about longevity aside, the former doctor pointed out some of the challenges that come with longer lifespans.

“We have an aging population [in the Netherlands], like in most places. People tend to get older, but they live longer usually with certain [health] conditions, with reduced mobility, etc., very similar to here,” Kuipers said.

Kuipers said his country is also experiencing a shortage in health care personnel, even as the number of working men and women affiliated with the health care industry takes up an increasing percentage of the workforce.

“If you look at the Netherlands, at the moment, one out of every six people with a job works in health care,” he said. That figure includes not just nurses or physicians, but also those serving the health care industry in human resources, finance and legal matters.

If the current pattern continues, one in five Dutch jobs will be related to health care by the year 2030, and that number will increase to one in four by the year 2040. Kuipers said this pattern will be very, very difficult, if not impossible, to sustain, “simply because we’re also going to need people in other areas of society.”

Given that health care is very labor intensive, Kuipers said governments and societies have no choice but to think of ways to meet the demands in a different, yet still effective way, to successfully cope with changing demographics.

In addition to the shortage of manpower, increased life expectancy also requires more money to care for the elderly, causing each country and government to think harder about budget priorities.

“Like the U.S., we have many burning issues, whether it’s energy transmission, preparation for climate change, infrastructure, you name it – the question of how to deliver and provide high-quality, good-access care to everyone while also limiting the increase in budget, that is very, very relevant, like it is here,” the Dutch minister said.

The Netherlands has universal health insurance and caps most people’s out of pocket expenses at 385 euros a year, a little more than 400 U.S. dollars a year.

“So far we [the country as a whole] can still afford this,” he said, “but it’s a continuous debate.”

The problem is especially acute in the case of certain very expensive drugs, the cost of which is increasing “very, very rapidly” and putting the “solidarity underlying our system” under pressure, the minister said.

He cited “orphan drugs,” which are needed by only a small number of people but are often a matter of life and death for those patients.

Kuipers and the Dutch delegation are among over 10,000 health science professionals and government officials from around the world who gathered in Boston this week to exchange ideas and find out the latest in health science at a biotech trade fair put together by the Biotechnology Innovation Organization.

El Nino has officially returned and is likely to yield extreme weather later this year, from tropical cyclones spinning toward vulnerable Pacific islands to heavy rainfall in South America to drought in Australia. 

After three years of the La Nina climate pattern, which often lowers global temperatures slightly, the hotter El Nino is back in action, according to an advisory issued on Thursday by the U.S. National Oceanic and Atmospheric Administration’s Climate Prediction Center. 

El Nino is born out of unusually warm waters in the Eastern Pacific, near the coast of South America, and often accompanied by a slowing down or reversal of the easterly trade winds. 

“In May, weak El Nino conditions emerged as above-average sea surface temperatures strengthened across the equatorial Pacific Ocean,” the advisory said. 

The last time an El Nino was in place, in 2016, the world saw its hottest year on record. Coupled with warming from climate change, 2023 or 2024 could reach new highs. 

Declaring El Nino 

Most experts look to two agencies for confirmation that El Nino has kicked off — NOAA and Australia’s Bureau of Meteorology (BOM). The two agencies use different metrics for declaring El Nino, with the Australian definition slightly stricter. 

NOAA calls an El Nino when ocean temperatures in the eastern and central equatorial Pacific have been 0.5 Celsius (0.9 Fahrenheit) higher than normal for the preceding month, and has lasted or is expected to continue for another five consecutive, overlapping three-month periods. The agency also looks at a weakening of the trade winds and cloud cover. 

Australia’s BOM needs things to be hotter, with the key regions of eastern Pacific 0.8C (1.5F) warmer than average. 

On Tuesday, Australia issued their own bulletin, noting a 70% chance of El Nino developing this year. 

NOAA said there is a 56% chance that when this El Nino peaks in strength — normally during the Northern Hemisphere winter — it will be a strong event, meaning that Eastern Pacific sea surface temperatures are at least 1.5C higher than normal. 

This could yield more intense impacts — from droughts to cyclones — across the world. 

Still, impacts vary and El Ninos come in “two flavors,” said atmospheric scientist Marybeth Arcodia at Colorado State University. 

Those with their warmest waters near the west coast of South America are deemed Eastern Pacific events, such as the strong 1997-98 El Nino. The other arises in the Central Pacific, near the equator around Hawaii, as was the case in the most recent 2015-16 event. Weather anomalies can be more extreme depending on where waters are warmest, making things drier or wetter in certain regions. 

Some forecast models predict the 2023-24 winter to be a Central Pacific El Nino. 

Agriculture impacts 

Early signs of hot, dry weather caused by El Nino are threatening food producers across Asia, while American growers are counting on heavier summer rains from the weather phenomenon to alleviate the impact of severe drought.

The El Nino could lead to winter crop production falling 34% from record highs in Australia, and also impacting palm oil and rice production in Indonesia, Malaysia — which supply 80% of the world’s palm oil — and Thailand.

In India, a country that largely depends on the monsoon rains for its summer crop, impacts from El Nino could be offset by the Indian Ocean Dipole, or the Indian Nino, yet below normal rainfall was expected over north-western parts of the country.

Schools across the U.S. East Coast canceled outdoor activities, airline traffic slowed, and millions of Americans were urged to stay indoors Wednesday as smoke from Canadian wildfires drifted south, blanketing cities in thick, yellow haze.

The U.S. National Weather Service issued air quality alerts for virtually the entire Atlantic seaboard. Health officials from Vermont to South Carolina and as far west as Ohio and Kansas warned residents that spending time outdoors could cause respiratory problems due to high levels of fine particulates in the atmosphere.

“It’s critical that Americans experiencing dangerous air pollution, especially those with health conditions, listen to local authorities to protect themselves and their families,” U.S. President Joe Biden said on Twitter.

U.S. private forecasting service AccuWeather said thick haze and soot extending from high elevations to ground level marked the worst outbreak of wildfire smoke to blanket the Northeastern U.S. in more than 20 years.

New York’s famous skyline, usually visible for miles, appeared to vanish in an otherworldly veil of smoke, which some residents said made them feel unwell.

“It makes breathing difficult,” Mohammed Abass said as he walked down Broadway in Manhattan. “I’ve been scheduled for a road test for driving, for my driving license today, and it was canceled.”

The smoky air was especially tough on people toiling outdoors, such as Chris Ricciardi, owner of Neighbor’s Envy Landscaping in Roxbury, New Jersey. He said he and his crew were curtailing work hours and wearing masks they used for heavy pollen.

“We don’t have the luxury to stop working,” he said. “We want to keep our exposure to the smoke to a minimum, but what can you really do about it?”

Angel Emmanuel Ramirez, 29, a fashion stylist at a Givenchy outlet in Manhattan, said he and fellow workers began feeling ill and closed up shop early when they realized the smell of smoke was permeating the store.

“It’s so intense, you would think the wildfire was happening right across the river, not up in Canada,” Ramirez said. New York Governor Kathy Hochul called the situation an “emergency crisis,” saying the air pollution index for parts of her state were eight times above normal.

Reduced visibility from the haze forced the Federal Aviation Administration to slow air traffic into the New York City area and Philadelphia from elsewhere on the East Coast and upper Midwest, with flight delays averaging about a half hour.

Schools up and down the East Coast called off outdoor activities, including sports, field trips and recesses.

A Broadway matinee of “Prima Facie” was halted after 10 minutes when actress Jodie Comer had difficulty breathing due to poor air quality. The show was restarted with understudy Dani Arlington going on for Comer in the role of Tessa, a production spokesperson said in a statement.

Even Major League Baseball was impacted, as the New York Yankees and the Philadelphia Phillies both postponed home games scheduled for Wednesday. A National Women’s Soccer League match in Harrison, New Jersey, was also rescheduled, as was a WNBA women’s basketball game in Brooklyn.

‘Unhealthy and ‘hazardous’

In some areas, the air quality index (AQI), which measures major pollutants including particulate matter produced by fires, was well above 400, according to Airnow, which sets 100 as “unhealthy” and 300 as “hazardous.”

At noon (1600 GMT), Bethlehem, Pennsylvania, was recording the nation’s worst air quality index, with an AQI reading of 410. Among major cities, New York had the highest AQI in the world on Wednesday afternoon at 342, about double the index for chronically polluted cities such as Dubai (168) and Delhi (164), according to IQAir.

Smoke drifting from Canada

Smoke billowed over the U.S. border from Canada, where hundreds of forest fires have scorched 3.8 million hectares and forced 120,000 people from their homes in an unusually early and intense start to the wildfire season.

The skies above New York and many other North American cities grew progressively hazier through Wednesday, with an eerie yellowish tinge filtering through the smoky canopy. The air smelled like burning wood.

Wildfire smoke has been linked with higher rates of heart attacks and strokes, increases in emergency room visits for asthma and other respiratory conditions, eye irritation, itchy skin and rashes, among other problems.

A Home Depot store in Manhattan sold out of air purifiers and masks. New York Road Runners canceled events intended to mark Global Running Day.

“This is not the day to train for a marathon or to do an outside event with your children,” New York Mayor Eric Adams advised. “If you are older or have heart or breathing problems or an older adult, you should remain inside.”

Pedestrians donned face masks in numbers that brought to mind the worst days of the coronavirus pandemic.

Tyrone Sylvester, 66, playing chess in Manhattan’s Union Square as he has on most days for 30 years, but wearing a mask, said he had never seen the city’s air quality so bad.

“When the sun looks like that,” he said, pointing out the bronze-like orb visible through the smoky sky, “we know something’s wrong. This is what global warming looks like.”

Poor air quality is likely to persist into the weekend, with a developing storm system expected to shift the smoke westward across the Great Lakes and deeper south through the Ohio Valley and into the mid-Atlantic region, AccuWeather said.

Most transplanted hearts are from donors who are brain dead, but new research shows a different approach can be just as successful and boost the number of available organs.

It’s called donation after circulatory death, a method long used to recover kidneys and other organs but not more fragile hearts. Duke Health researchers said Wednesday that using those long-shunned hearts could allow possibly thousands more patients a chance at a lifesaving transplant — expanding the number of donor hearts by 30%.

“Honestly if we could snap our fingers and just get people to use this, I think it probably would go up even more than that,” said transplant surgeon Dr. Jacob Schroder of Duke University School of Medicine, who led the research. “This really should be standard of care.”

The usual method of organ donation occurs when doctors, through careful testing, determine someone has no brain function after a catastrophic injury — meaning they’re brain dead. The body is left on a ventilator that keeps the heart beating and organs oxygenated until they’re recovered and put on ice.

In contrast, donation after circulatory death occurs when someone has a nonsurvivable brain injury but, because all brain function hasn’t yet ceased, the family decides to withdraw life support and the heart stops. That means organs go without oxygen for a while before they can be recovered — and surgeons, worried the heart would be damaged, left it behind.

What’s changed: Now doctors can remove those hearts and put them in a machine that “reanimates” them, pumping through blood and nutrients as they’re transported –- and demonstrating if they work OK before the planned transplant.

Wednesday’s study, conducted at multiple hospitals around the country, involved 180 transplant recipients, half who received DCD hearts and half given hearts from brain-dead donors that were transported on ice.

Survival six months later was about the same –- 94% for the recipients of cardiac-death donations and 90% for those who got the usual hearts, the researchers reported in the New England Journal of Medicine.

The findings are exciting and show “the potential to increase fairness and equity in heart transplantation, allowing more persons with heart failure to have access to this lifesaving therapy,” transplant cardiologist Dr. Nancy Sweitzer of Washington University in St. Louis, who wasn’t involved with the study, wrote in an accompanying editorial.

Last year, 4,111 heart transplants were performed in the U.S., a record number but not nearly enough to meet the need. Hundreds of thousands of people suffer from advanced heart failure but many are never offered a transplant and still others die waiting for one.

Researchers in Australia and the U.K. first began trying DCD heart transplants about seven years ago. Duke pioneered the U.S. experiments in late 2019, one of about 20 U.S. hospitals now offering this method. Last year, there were 345 such heart transplants in the U.S., and 227 so far this year, according to the United Network for Organ Sharing.

In the Duke-led study, nearly 90% of the DCD hearts recovered wound up being transplanted, signaling that it’s worthwhile for more hospitals to start using the newer method.

Sweitzer noted that many would-be donors have severe brain injuries but don’t meet the criteria for brain death, meaning a lot of potentially usable hearts never get donated. But she also cautioned that there’s still more to learn, noting that the very sickest patients on the waiting list were less likely to receive DCD hearts in the study.

Schroder said most who received DCD hearts already had implanted heart pumps that made the transplant more difficult to perform, even if they weren’t ranked as high on the waiting list.

The study was funded by TransMedics, which makes the heart storage system.

Kilauea, one of the most active volcanoes in the world, began erupting Wednesday after a three-month pause, displaying spectacular fountains of mesmerizing, glowing lava that’s a safe distance from people and structures in a national park on the Big Island.

The U.S. Geological Survey’s Hawaiian Volcano Observatory said in a statement that a glow was detected in webcam images from Kilauea’s summit early in the morning, indicating that an eruption was occurring within the Halemaumau crater in the summit caldera.

The images show fissures at the base of the crater generating lava flows on the crater floor’s surface, the observatory said.

Before issuing the eruption notice, the observatory said increased earthquake activity and changes in the patterns of ground deformation at the summit started Tuesday night, indicating the movement of magma in the subsurface.

“We’re not seeing any signs of activity out on the rift zones right now,” said Mike Zoeller, a geologist with the observatory. “There’s no reason to expect this to transition into a rift eruption that would threaten any communities here on the island with lava flows or anything like that.”

All activity was within a closed area of Hawaii Volcanoes National Park.

“The lava this morning is all confined within … the summit caldera. So plenty of room for it still to produce more without threatening any homes or infrastructure,” said park spokesperson Jessica Ferracane. “So that’s the way we like our eruptions here.”

She said park officials are bracing for crowds to arrive because visitors can see the eruption from many overlooks.

“Kilauea overlook was spectacular this morning,” she said of the vast lava lake. “It was molten red lava. There’s several areas of pretty robust fountaining. It’s just really, really pretty.”

The lava lake, covering the crater floor over lava that remained from previous eruptions, measured about 150 hectares about 6 a.m., Zoeller said. It measured about 1,300 meters wide.

Word was getting out and parking lots were starting to fill up at the park, Ferracane said, adding that she expected long lines getting into the park by evening.

Since the park is open 24 hours a day, visitors can beat the crowds by visiting between 9 p.m. and sunrise, Ferracane said.

She reminded visitors to stay out of closed areas and remain on marked trails for safety reasons, including avoiding gases from the eruption.

Two small earthquakes jolted Janice Wei awake. As a volunteer photographer for the park who lives in the nearby town of Volcano, she was able to see fountains she estimated to be 46 meters high around 4:30 a.m.

The volcano’s alert level was raised to warning status and the aviation color code went to red as scientists evaluate the eruption and associated hazards.

Kilauea, Hawaii’s second largest volcano, erupted from September 2021 until last December. For about two weeks in December, Hawaii’s biggest volcano, Mauna Loa, also was erupting on Hawaii’s Big Island.

After a short pause, Kilauea began erupting again in January. That eruption lasted for 61 days, ending in March.

This eruption looks very similar, Zoeller said.

A 2018 Kilauea eruption destroyed more than 700 homes.

Before the major 2018 eruption, Kilauea had been erupting since 1983, and streams of lava occasionally covered farms and homes. During that time, the lava sometimes reached the ocean, causing dramatic interactions with the water.

As communities in countries rich and poor face soaring costs from extreme weather and rising seas, governments are grappling with how to set up a new fund to tackle “loss and damage” driven by global warming.

The topic was for years controversial at U.N. climate talks, as wealthy nations rejected demands for “compensation” for the impacts of their high share of the planet-heating emissions that are turbo-charging floods, droughts and storms around the world.

However, at the COP27 climate summit in Egypt last November, a group of 134 African, Asian and Latin American states and small island nations finally won agreement on a new fund that will pay to repair devastated property, or preserve cultural heritage before it disappears forever.

But the details of where the money will come from and how it will be disbursed were left to be worked out by this December’s COP28 conference in Dubai.

As mid-year U.N. climate talks got underway in Bonn in June, Saleemul Huq, director of the Dhaka-based International Centre for Climate Change and Development, called on the United Arab Emirates to declare its intention for COP28 — which it will host — to create the “Dubai Loss and Damage Fund.”

Here’s why the issue of “loss and damage” has grown in importance this past decade — and where the sticking points in finding finance to address it could lie.

What is climate change “loss and damage”?

“Loss and damage” refers to the physical and mental harm that happens to people and places when they are not prepared for climate-driven impacts, and are unable to adjust the way they live to protect themselves from longer-term shifts.

It can occur both from fast-moving weather disasters made stronger or more frequent by warming temperatures — such as floods or hurricanes — as well as from slower-developing stresses like persistent drought and sea levels creeping higher.

A large share of “loss and damage” can be measured in financial terms, like the cost of wrecked homes and infrastructure.

But there are other non-economic losses that are harder to quantify, such as graveyards and family photos being washed away, or Indigenous cultures that could disappear if a whole community must move because their land is no longer habitable.

A June 2022 report released by a forum of 55 climate-vulnerable countries — from Bangladesh to South Sudan — found they would have been 20% wealthier had it not been for climate change and the $525 billion in losses inflicted on them by shifts in temperature and rainfall over the past two decades.

Often the poorest people lack the means to recover what they have lost, particularly as aid fails to keep up with growing needs, as seen with last year’s huge floods in Pakistan or the drought that has left tens of millions hungry in the Horn of Africa.

What funding is on offer when loss and damage happens — and how can more be raised?

So far there has been very little money available apart from aid provided through the international humanitarian system to respond to disasters — which every year faces shortfalls.

A 2022 study by anti-poverty charity Oxfam found that aid needs in response to weather disasters had skyrocketed more than eightfold in the last 20 years.

But U.N.-coordinated humanitarian emergency appeals are, on average, only 60% funded.

“There is not enough money for humanitarian action — even to do the first-phase response [to disasters], never mind the preparedness, resilience [and] longer-term early recovery piece,” said Debbie Hillier, who manages flood resilience programs for Mercy Corps.

According to a 2018 study by researchers at the Basque Centre for Climate Change, the costs of loss and damage in low- and middle-income countries could reach between $290 billion and $580 billion a year by 2030.

But rich countries are already struggling to meet a goal to channel $100 billion annually to vulnerable countries for reducing emissions and adapting to climate change.

Some donor countries, including a few European nations, Canada and New Zealand, have already agreed to provide loss and damage funding to poorer nations – although so far, those pledges total only about $275 million.

Given this, climate justice activists have long argued for the need to find innovative sources for loss and damage funding, based on levies and taxation.

Those include a controversial proposal — backed by the U.N. chief — for rich governments to tax the windfall profits of fossil fuel companies.

Other ideas that have gained ground include levying a small fee on international flights – which contribute to climate-heating emissions – and a global tax on financial market transactions, which could be distributed by the new fund.

The most concrete loss and damage funding scheme so far, the “Global Shield Against Climate Risks”, aims to boost insurance coverage for vulnerable countries and communities, attracting about $200 million at its COP27 launch, largely from Germany.

It will expand initiatives — from subsidized insurance coverage to stronger social protection schemes and pre-approved disaster financing — that can swiftly channel support to disaster-hit poorer countries’ own contingency plans.

But many climate campaigners say insurance cannot be a lasting answer, with losses expected to soar and even become uninsurable as climate disasters intensify.

What are the obstacles to setting up a loss and damage fund?

A “Transitional Committee” is meeting regularly this year to work out the form and scope of the new loss and damage fund, and how to fill its coffers.

Observers say the discussions have progressed constructively — and are hoping this month’s Bonn climate talks will add political momentum. But there is disagreement on which parts of loss and damage finance should fall under the new fund’s remit.

Some countries, notably the United States, want the fund to focus tightly on two key areas less well-covered by humanitarian agencies — “slow onset” disasters, from desertification to islands sinking as seas rise, and “non-economic losses”.

That would also include support for communities — or even whole island nations — to relocate should they no longer be able to continue living in their current homes.

Climate justice campaigners and others, meanwhile, are pushing for the new fund to have a broader scope, which would include helping finance the humanitarian response to climate disasters as well as efforts to cover gaps, especially in terms of building resilience.

A report last month by the Zurich Flood Resilience Alliance outlined lessons learned by the aid sector that could help the new loss and damage fund operate effectively.

Its recommendations included a warning to donors not to re-label their humanitarian aid as loss and damage funding, and to find new sources of finance.

It also stressed the need to use existing systems to deliver aid on the ground fast, find ways to get funding to fragile and conflict-hit states, and work with local groups.

The key will be to agree on how loss and damage action can both benefit from — and amplify — the work already being done by humanitarian agencies to protect vulnerable communities, experts say.

“We can’t allow the accountability to be shifted outside the [U.N. climate] system — for a very simple reason: 90% of disasters we are facing today are climate-related,” said Harjeet Singh, head of global political strategy for Climate Action Network International.

“The loss and damage fund has to be the top-level mechanism that should have oversight on whether people are getting sufficient support or not.”

China, where COVID-19 was first identified in humans more than three years ago, expects its current wave of infection to hit as many as 65 million cases per week by late June, according to official accounts of models presented at a medical conference.

While that may be an exhausting number to a post-pandemic world wearied by a still rising toll of 767 million confirmed cases and more than 6.9 million deaths, the predicted onslaught in China comes with less severe symptoms, Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, told the official newspaper Beijing Daily.

And, experts say, the outbreak is likely to be confined to China. Raj Rajnarayanan, assistant dean of research and associate professor at the New York Institute of Technology and a top COVID-variant tracker, told Fortune that when it comes to XBB variants, “the rest of the world has seen them all.” But up until recently, “China hasn’t.”

Respiratory disease specialist Zhong Nanshan, who spoke on May 22 at a conference in the southern city of Guangzhou, said the current wave of infections that started in late April was “anticipated.” His modeling suggested that by the end of June, the weekly number of infections will peak at 65 million, according to the official Global Times.

After Beijing relaxed the draconian lockdowns enforced under its “zero-COVID” policy, an omicron variant different from the current one ripped through China in December 2022 and January 2023.

About 80% of China’s 1.4 billion people were infected during that wave, Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said in January, CNN reported. Patients packed hospitals and families waited for days to cremate those who died.

The latest COVID wave is something most people do not take seriously, said Mr. Lin, who requested anonymity due to the sensitivity of the issue. The resident of Quanzhou in Fujian province said, “They go about their activities normally and don’t do any protection. No one wears masks.”

Mr. Lin told VOA Mandarin he was infected in mid-December 2022, soon after Beijing lifted the lockdowns that had sent the world’s second-largest economy into a tailspin.

He realized he was infected — again — in May. Mr. Lin said he knew others who were likely reinfected and didn’t even bother to take a COVID test because their symptoms were so mild.

Mr. Zhang, who was infected for the first time in December, told VOA Mandarin he was infected a second time on a business trip to Shanghai and Beijing in May. The Hunan province resident, who asked to use a pseudonym to avoid attracting official attention, thought he had caught a cold because of the air conditioning he encountered on his trip.

But he took a test while still in Beijing and with a positive result, ended up at a hospital where he said a doctor told him, “People all over the country are like this. No need for medical attention at all. Just go home.”

After suffering four days with insomnia, loss of appetite and recurring fever, Mr. Zhang went to another Beijing hospital. Admitted, he was given Paxlovid, an anti-coronavirus drug developed by Pfizer.

“I took the medicine at noon and felt relieved at night,” he told VOA Mandarin.

During his hospital stay, Mr. Zhang said, “All the infectious disease wards were full, and there was a long queue to get an appointment. The hospital used wards of other departments for patients from the Infectious Diseases Department.”

Jin Dong-yan, a biochemistry professor with the Li Ka-shing Faculty of Medicine at the University of Hong Kong, told VOA Mandarin there is not much difference between the current situation in China and in the U.S., but the Chinese media devote more coverage to the outbreak.

Jin said, “In fact, looking at the data, the U.S. has experienced about four peaks after the outbreak last year, but each peak is getting smaller and smaller.”

The United States, by comparison, was reporting more than 5 million cases a week at its most recent peak in January.

The World Health Organization declared COVID-19 over as a global health emergency on May 5.

Like the U.S., China stopped providing weekly case updates in May, making it difficult to know the true extent of the current outbreak.

The U.S. Centers for Disease Control and Prevention recorded more than 1.1 million deaths in the U.S. involving COVID-19 from January 4, 2020, to May 27, 2023. 

In China, from January 3, 2020, to May 31, 2023, there have been almost 100 million confirmed cases of COVID-19, with more than 120,000 deaths reported by Beijing to WHO.
