A global hunger crisis has left more than 700 million people not knowing when or if they will eat again, and demand for food is rising relentlessly while humanitarian funding is drying up, the head of the United Nations food agency said Thursday.

World Food Program Executive Director Cindy McCain told the U.N. Security Council that because of the lack of funding, the agency has been forced to cut food rations for millions of people, and “more cuts are on the way.”

“We are now living with a series of concurrent and long-term crises that will continue to fuel global humanitarian needs,” she said. “This is the humanitarian community’s new reality — our new normal — and we will be dealing with the fallout for years to come.”

The WFP chief, the widow of the late U.S. senator John McCain, said the agency estimates that nearly 47 million people in over 50 countries are just one step from famine — and a staggering 45 million children younger than 5 are now estimated to suffer from acute malnutrition.

According to WFP estimates from 79 countries where the Rome-based agency operates, up to 783 million people — one in 10 of the world’s population — still go to bed hungry every night. More than 345 million people are facing high levels of food insecurity this year, an increase of almost 200 million people from early 2021 before the COVID-19 pandemic, the agency said.

At the root of the soaring numbers, WFP said, is “a deadly combination of conflict, economic shocks, climate extremes and soaring fertilizer prices.”

The economic fallout from the pandemic and the war in Ukraine have pushed food prices out of the reach of millions of people across the world at the same time that high fertilizer prices have caused falling production of maize, rice, soybeans and wheat, the agency said.

“Our collective challenge is to ramp up the ambitious, multi-sectoral partnerships that will enable us to tackle hunger and poverty effectively, and reduce humanitarian needs over the long-term,” McCain urged business leaders at the council meeting focusing on humanitarian public-private partnerships. The aim is not just financing, but also finding innovative solutions to help the world’s neediest.

Michael Miebach, CEO of Mastercard, told the council that “humanitarian relief has long been the domain of government” and development institutions, and the private sector was seen as a source of financial donations for supplies.

“Money is still important, but companies can offer so much more,” he said. “The private sector stands ready to tackle the challenges at hand in partnership with the public sector.”

Miebach stressed that “business cannot succeed in a failing world” and humanitarian crises impact fellow citizens of the world. A business can use its expertise, he said, to strengthen infrastructure, “innovate new approaches and deliver solutions at scale” to improve humanitarian operations.

Jared Cohen, president of global affairs at Goldman Sachs, told the council that the revenue of many multinational companies rivals the GDP of some of the Group of 20 countries with the largest economies. And he said five American companies and many of their global counterparts have over 500,000 workers — more than the population of up to 20 U.N. member nations.

“Today’s global firms have responsibilities to our shareholders, clients, staff, communities, and the rules-based international order that makes it possible for us to do business,” he said.

Cohen said businesses can fulfill those responsibilities during crises first by not scrambling “to reinvent the wheel every time,” but by drawing on institutional memory and partnering with other firms and the public sector.

He said businesses also need “to act with speed and innovate in real time,” use local connections, and bring their expertise to the humanitarian response.

Lana Nusseibeh, the United Arab Emirates ambassador, said the U.N. appealed for over $54 billion this year, “and until now, 80% of those funds remain unfulfilled,” which shows that “we are facing a system in crisis.”

She said public-private partnerships that were once useful additions are now crucial to humanitarian work.

Over the past decade, Nusseibeh said, the UAE has been developing “a digital platform to support a government’s ability to better harness international support in the wake of natural disasters.” The UAE has also established a major humanitarian logistics hub and is working with U.N. agencies and private companies on new technologies to reach those in need, she said.

U.S. Ambassador Linda Thomas-Greenfield said the funding gap has left the world’s most vulnerable people “in a moment of great peril.”

She said companies have stepped up, including in Haiti and Ukraine and to help refugees in the United States, but for too long, “we have turned to the private sector exclusively for financing.”

Businesses have shown “enormous generosity, but in 2023 we know they have so much more to offer. Their capacities, their know-how, and innovations are tremendously needed,” Thomas-Greenfield said. “The public sector must harness the expertise of the private sector and translate it into action.”

Authorities in India are scrambling to contain a rare outbreak of Nipah, a virus spread from animals to humans that causes deadly fever and has a high mortality rate. Here is a look at what is known so far:

What is the Nipah virus? 

The first Nipah outbreak was recorded in 1998 after the virus spread among pig farmers in Malaysia. The virus is named after the village where it was discovered. 

Outbreaks are rare but Nipah has been listed by the World Health Organization — alongside Ebola, Zika and COVID-19 — as one of several diseases deserving of priority research because of their potential to cause a global epidemic. 

Nipah usually spreads to humans from animals or through contaminated food, but it can also be transmitted directly between people.  

Fruit bats are the natural carriers of the virus and have been identified as the most likely cause of subsequent outbreaks. 

Symptoms include intense fever, vomiting and a respiratory infection, but severe cases can involve seizures and brain inflammation that results in a coma. 

Patients have a mortality rate of between 40% and 75% depending on the public health response to the virus, the WHO says.

There is no vaccine for Nipah.

What has happened during previous outbreaks? 

The first Nipah outbreak killed more than 100 people in Malaysia and prompted the culling of 1 million pigs to try to contain the virus.  

It also spread to Singapore, with 11 cases and one death among slaughterhouse workers who had come into contact with pigs imported from Malaysia. 

Since then, the disease has mainly been recorded in Bangladesh and India, with both countries reporting their first outbreaks in 2001. 

Bangladesh has borne the brunt in recent years, with more than 100 people dying of Nipah since 2001.  

Two early outbreaks in India killed more than 50 people before they were brought under control. 

The southern state of Kerala has recorded two deaths from Nipah and four other confirmed cases since last month.  

Authorities there have closed some schools and instituted mass testing. 

This marks Kerala’s fourth recorded spate of Nipah cases in five years. The virus killed 17 people during the first instance in 2018.  

The state has stamped out previous outbreaks within weeks through widespread testing and strict isolation of those in contact with patients.

Are animal-to-human viruses becoming more frequent? 

Having first appeared thousands of years ago, zoonoses — diseases that can be transmitted from animals to humans — have multiplied over the past 20 to 30 years. 

The growth of international travel has allowed them to spread more quickly. 

By occupying increasingly large areas of the planet, experts say, humans also contribute to disruption of the ecosystem and increase the likelihood of random virus mutations that are transmissible to humans. 

Industrial farming increases the risk of pathogens spreading among animals while deforestation heightens contact among wildlife, domestic animals and humans. 

By mixing more, species will transmit their viruses more, which will promote the emergence of new diseases potentially transmissible to humans. 

Climate change will push many animals to flee their ecosystems for more livable lands, a study published by the scientific journal Nature warned in 2022. 

According to estimates published in the journal Science in 2018, there are 1.7 million unknown viruses in mammals and birds, with 540,000 to 850,000 of them having the capacity to infect humans.

Bangladesh is struggling with a record outbreak of dengue fever, with experts saying a lack of a coordinated response is causing more deaths from the mosquito-transmitted disease. 

The World Health Organization recently warned that diseases such as dengue, Zika, chikungunya and yellow fever caused by mosquito-borne viruses are spreading faster and further because of climate change. 

So far this year, 778 people in Bangladesh have died and 157,172 have been infected, according to the government’s Directorate General Health Services. The U.N. children’s agency says the actual numbers are higher because many cases are not reported. 

The previous highest number of deaths was in 2022, when 281 people are reported to have died during the entire year. 

Dengue is common in tropical areas and causes high fevers, headaches, nausea, vomiting, muscle pain and, in the most serious cases, internal bleeding that leads to death. 

Mohammed Niatuzzaman, director of the state-run Mugda Medical College and Hospital in Dhaka, said Thursday that Bangladesh is struggling to cope with the outbreak because of a lack of a “sustainable policy” and because many do not know how to treat it. 

Outside Dhaka and other big cities, medical professionals including nurses need better training in handling dengue cases, he said. 

He said authorities should include groups like city corporations and local governments in the fight against dengue, and researchers should study how to prepare for future outbreaks. 

Some residents of Dhaka are unhappy with the authorities. 

“Our house is in an area which is at risk of dengue. It has a higher quantity of waste and garbage. I’m cautious and use a mosquito net. Despite that, my daughter caught dengue,” said Zakir Hassain, a resident of Dhaka’s Basabo area.

“What will happen to those who are unaware? If the city corporation or ward commissioner took more care and sprayed insecticides, then we could have avoided the dengue outbreak,” he said.

One American and two Russian space crew members blasted off Friday aboard a Russian spacecraft from the Baikonur Cosmodrome in Kazakhstan on a mission to the International Space Station.

NASA astronaut Loral O’Hara and Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub lifted off on the Roscosmos Soyuz MS-24 spacecraft at 8:44 p.m. local time. O’Hara will spend six months on the ISS while Kononenko and Chub will spend a year there.

Neither O’Hara nor Chub has ever flown to space before, but they will be flying with veteran cosmonaut and mission commander Kononenko, who has made the trip four times already. The trio should arrive at the ISS after a three-hour flight.

When they get to the ISS, their module will dock and when the hatches open they will be met by seven astronauts and cosmonauts from the U.S., Russia, Denmark and Japan. Later in September, three of the ISS crew will depart, including NASA astronaut Frank Rubio who will have been there for more than a year.

According to NASA, when mission commander Kononenko finishes his tour to space in a year’s time, he will hold the record for the person who has spent the longest amount of time — more than a thousand days — in space.

NASA said on Thursday it has selected a research director to investigate UFO sightings on the recommendation of an independent panel of experts. 

Administrator Bill Nelson, who made the announcement, has yet to identify the appointee. 

The unidentified anomalous phenomena, or UAP, is the official term for what most call UFOs — unidentified flying objects. The panel, which included physicists, astronomers and biologists, wouldn’t say whether eyewitness accounts of UAP prove the existence of life beyond our horizons. 

That’s still an open question, according to Nelson. “If you ask me do I believe there’s life in a universe that’s so vast that it’s hard for me to comprehend how big it is, my personal answer is, ‘Yes,'” he said. 

In his statement, Nelson conceded that “[NASA scientists] don’t know what these UAP are.” 

In 2021, the national intelligence director published a comprehensive report, sharing never-before-seen scientific data and military observations on coastal sightings of UAP. Some of the high-flying objects are said to outpace and outmaneuver even the best fighter jets, without any apparent thrust or flight control systems. 

UAP have mystified Americans since June 1947, when newspapers first reported that a metallic “flying saucer” appeared in the sky over mountain ranges in Washington state. Sensational accounts of UAP sightings have cropped up all over the world since, including the debunked Roswell, New Mexico incident that made headlines that same year.

For the better part of a century, conspiracy theorists have accused the government of withholding facts or even lying to the public. But Nelson promised that NASA’s incoming research director would disclose all UAP-related developments to “shift the conversation about UAP from sensationalism to science.”

The director will manage “centralized communications, resources and data analytical capabilities to establish a robust database for the evaluation of future UAP,” NASA said. 

The appointment comes as academics claim to be making inroads in the search for extraterrestrial life. In recent weeks, the controversial Harvard astrophysicist Avi Loeb recovered tiny meteorite fragments off the coast of Papua New Guinea. His team is evaluating whether the unusual metallic samples are bits of alien technology. 

Some information for this report was provided by Reuters.

A government watchdog agency in France has ordered Apple to withdraw the iPhone 12 from the French market, saying it emits levels of electromagnetic radiation that are too high.

The National Frequency Agency, which oversees radio-electric frequencies as well as public exposure to electromagnetic radiation, called on Apple in a statement Tuesday to “implement all available means to rapidly fix this malfunction” for phones already being used.

Corrective updates to the iPhone 12 will be monitored by the agency, and if they don’t work, “Apple will have to recall” phones that have already been sold, according to the French regulator’s statement.

Apple disputed the findings and said the device complies with all regulations governing radiation.

The agency, which is known by the French acronym ANFR, said it recently checked 141 cellphones, including the iPhone 12, for electromagnetic waves capable of being absorbed by the body.

It said it found a level of electromagnetic energy absorption of 5.74 watts per kilogram during tests of a phone in a hand or a pocket, higher than the European Union standard of 4 watts per kilogram.

The agency said the iPhone 12 met the threshold when radiation levels were assessed for a phone kept in a jacket or in a bag.

Apple said the iPhone 12, which was released in late 2020, has been certified by multiple international bodies and complies with all applicable regulations and standards for radiation around the world.

The U.S. tech company said it has provided the French agency with multiple lab results carried out both by the company and third-party labs proving the phone’s compliance.

Jean-Noël Barrot, France’s minister in charge of digital issues, told France Info radio that the National Frequency Agency “is in charge of controlling our phones which, as there are software updates, may emit a little more or a little less electromagnetic waves.”

He said that the iPhone 12 radiation levels are “slightly higher” than the standards but “significantly lower than levels where scientific studies consider there may be consequences for users. But the rule is the rule.”

Cellphones have been labeled as “possible” carcinogens by the World Health Organization’s cancer research arm, putting them in the same category as coffee, diesel fumes and the pesticide DDT. The radiation produced by cellphones cannot directly damage DNA and is different from stronger types of radiation like X-rays or ultraviolet light.

In 2018, two U.S. government studies that bombarded mice and rats with cellphone radiation found a weak link to some heart tumors, but federal regulators and scientists said it was still safe to use the devices. Scientists said those findings didn’t reflect how most people use their cellphones and that the animal findings didn’t translate into a similar concern for humans.

Among the largest studies on potential dangers of cellphone use, a 2010 analysis in 13 countries found little or no risk of brain tumors.

People’s mobile phone habits also have changed substantially since the first studies began and it’s unclear if the results of previous research would still apply today.

Since many tumors take years to develop, experts say it’s difficult to conclude that cellphones have no long-term health risks. Experts have recommended that people concerned about their cellphone radiation exposure use earphones or switch to texting.

Malawi is extending the maximum age of children eligible for the polio vaccination from 5 to 15. Since the discovery last year of its first polio case 30 years after the country eradicated the disease, the number of cases has increased to five this year — the latest victim being 14 years old.  

Malawi health authorities made the announcement Tuesday at the launch of the nationwide polio vaccination campaign that is targeting about 9.7 million children.     

Beston Chisamile, the secretary of health in Malawi, said the children will be vaccinated on their doorsteps.  

“Our health workers will be visiting parents’ homes and vaccinating [children],” said Chisamile. “We are aware that some of them were skipped in the previous vaccination phase, and we want to try and reach the majority.” 

Chisamile said the maximum age of children to be vaccinated was extended from 5 to 15 years of age after the discovery of another case this year of a 14-year-old. 

Polio resurfaces 

Polio is a viral disease that causes irreversible paralysis and has no cure. The disease can be prevented, however, by the administration of effective vaccines. 

Thirty years after it eradicated the disease, Malawi confirmed its first polio case in February 2022. Since then, the number of confirmed cases has increased to five. 

Malawi is among several countries in Africa that have registered confirmed cases of polio in recent years.  

The World Health Organization said in a statement released on August 30 that 187 confirmed cases of circulating variant poliovirus have been reported in 21 countries in the African region. 

The WHO said that although the region has been certified free of wild poliovirus, it is witnessing a resurgence of the disease because of a decline in immunization coverage and the disruption of essential health services caused by the COVID-19 pandemic. 

A push to vaccinate

UNICEF, WHO, the Centers for Disease Control and Prevention, and other partners of the Global Polio Eradication Initiative are leading the vaccination campaign in Malawi. 

The UNICEF representative in Malawi, Shadrack Omol, said the United Nations’ children’s agency so far has procured and distributed 10.2 million doses of the polio vaccine across all 29 districts and 865 health facilities in Malawi. 

Omol also said UNICEF has installed 250 new refrigerators, repaired 125 broken ones, and distributed essential cold storage equipment. 

 

Health authorities in Malawi have noted with concern, though, that some parents refuse to have their children vaccinated because of cultural and religious beliefs. 

 

Authorities say this will impede efforts to meet vaccination targets.  

 

George Jobe, the executive director of the Malawi Health Equity Network, told VOA that his organization has been educating people about the importance of vaccinating children against polio. 

 

“We still maintain our plea and health education to those who don’t believe in medication that they should be mindful of the right to the good health of their children,,” said Jobe. “The children will make their own choices when they grow up. But at the moment, parents must not apply whatever they believe in on their children.”

Most Americans should get an updated COVID-19 vaccine, health officials said Tuesday.

Advisers to the Centers for Disease Control and Prevention endorsed the new shots for everyone 6 months and older and the agency’s director quickly signed off Tuesday on the panel’s recommendation. That means doses should be available this week, some as early as Wednesday.

The severity of the COVID-19 pandemic has faded, but there are still thousands of hospitalizations and hundreds of deaths in the U.S. each week. Hospitalizations have been increasing since late summer, though the latest data indicate infections may be starting to level off, particularly in the South.

Still, experts worry that immunity from previous vaccinations and infections is fading in many people, and a new shot would save many lives.

According to a survey last month that the CDC cited, about 42% said they would definitely or probably get the new vaccine. Yet only about 20% of adults got an updated booster when it was offered a year ago.

Doctors hope enough people get vaccinated to help avert another “tripledemic” like last year when hospitals were overwhelmed with an early flu season, an onslaught of RSV, or respiratory syncytial virus, and yet another winter coronavirus surge.

Here is what you need to know about the new COVID-19 shots:

Who should get the updated vaccine?

The Food and Drug Administration approved the updated shots from Pfizer and Moderna for adults and children as young as 6 months. FDA said starting at age 5, most people can get a single dose even if they’ve never had a prior COVID-19 shot. Younger children might need additional doses depending on their history of COVID-19 infections and vaccinations.

The CDC decides how best to use vaccines and makes recommendations for U.S. doctors and the general public. The agency’s panel of outside experts recommended the updated COVID-19 shots by a vote of 13-1. The no vote came from a panel member who had argued that the new shots should initially be recommended only for older people and others at greatest risk of severe illness. But other panel members said all ages could — and should — benefit.

“We need to make vaccination recommendations as clear as possible,” said one panel member, Dr. Camille Kotton, an infectious diseases doctor at Massachusetts General Hospital.

Where can i get a shot?

The new vaccine will be available at pharmacies, health centers and some doctor offices. Locations will be listed on the government’s vaccines.gov website. The list price of a dose of each shot is $120 to $130, according to the manufacturers. But federal officials said the new COVID-19 shots still will be free to most Americans through private insurance, Medicare or Medicaid. For the uninsured or underinsured, the CDC is working with health departments, clinics and certain pharmacies to temporarily provide free shots.

On Tuesday, a Pfizer official said his company expected to have doses available at some U.S. locations as early as Wednesday.

Why more COVID-19 shots?

Similar to how flu shots are updated each year, the FDA gave COVID-19 vaccine makers a new recipe for this fall. The updated shots have a single target, an omicron descendant named XBB.1.5. It’s a big change. The COVID-19 vaccines offered since last year are combination shots targeting the original coronavirus strain and a much earlier omicron version, making them very outdated.

Pfizer, Moderna and Novavax all have brewed new supplies, and the FDA on Monday approved shots from Pfizer and Moderna. Novavax’s updated vaccine is still under review.

Will they be effective enough?

Health officials are optimistic, barring a new mutant. As expected, XBB.1.5 has faded away in the months it took to tweak the vaccine. Today, there is a soup of different coronavirus variants causing illness, and the most common ones are fairly close relatives. Recent lab testing from vaccine makers and other research groups suggest the updated shots will offer crossover protection.

Earlier vaccinations or infections have continued to help prevent severe disease and death but protection wanes over time, especially against milder infections as the virus continually evolves. The FDA did allow seniors and others at high risk to get an extra booster dose last spring. But most Americans haven’t had a vaccination in about a year.

Can I get a flu shot and COVID-19 shot at the same time?

Yes. The CDC says there is no difference in effectiveness or side effects if people get those vaccines simultaneously, although one in each arm might be more comfortable. The CDC urges a yearly flu shot for pretty much everyone ages 6 months and up. The best time is by the end of October.

An American researcher was “doing well” at a Turkish hospital, officials said Tuesday, after rescuers pulled him out of a cave where he fell seriously ill and became trapped 1,000 meters (more than 3,000 feet) below its entrance for over a week.

Rescuers from Turkey and across Europe cheered and clapped as Mark Dickey, a 40-year-old experienced caver, emerged from Morca Cave in southern Turkey’s Taurus Mountains strapped to a stretcher at 12:37 a.m. local time Tuesday. He was whisked to the hospital in the nearby city of Mersin in a helicopter.

Dickey fell ill on Sept. 2 with stomach bleeding. What caused his condition remained unclear.

Lying on the stretcher surrounded by reporters shortly after his rescue, he described his nine-day ordeal as a “crazy, crazy adventure.”

“It is amazing to be above ground again,” he said. A well-known cave researcher and a cave rescuer who had participated in many international expeditions, Dickey thanked the international caving community, Turkish cavers and Hungarian Cave Rescue, among others.

Dickey, who is from Croton-on-Hudson, New York, was part of an expedition to map the Morca Cave, Turkey’s third deepest, when he became sick. As he was too frail to climb out himself, cave rescue teams from Europe scrambled to help save him, mounting a challenging operation that involved pulling him up the cave’s steep vertical sections and navigating through mud and water at low temperatures in the horizontal sections.

Rescuers had to widen some of the cave’s narrow passages, install ropes to pull him up vertical shafts on a stretcher and set up temporary camps along the way before the operation could begin.

“It was great to see him finally get out because it was very dire in the early days of this rescue,” Carl Heitmeyer of the New Jersey Initial Response Team and a friend of Dickey’s told NBC’s “Today” show.

Asked whether he believes Dickey would return to caving, Heitmeyer said: “I hope his mom’s not watching, but I would bet on it.”

Among those who rushed to the Taurus Mountains was Dr. Zsofia Zador, a caving enthusiast and medical rescuer from the Hungarian rescue team, who was among the first to treat Dickey inside the cave.

Zador, an anesthesiologist and intensive care specialist from Budapest, was on her way to the hospital to start her early morning shift on Sept. 2, when she got news of Dickey’s condition.

The 34-year-old quickly arranged for a colleague to take her shift and rushed to gather her caving gear and medical equipment, before taking a plane to Turkey to join the rescue mission, she told The Associated Press by telephone from the camp near the entrance of the cave.

“He was relieved, and he was hopeful,” she said when asked to describe Dickey’s reaction when he saw her in the cave. “He was quite happy. We are good friends.”

Zador said Dickey was hypovolemic — or was suffering from loss of fluid and blood — but said he was in a “stable condition” by the time she reached him because paramedics had “treated him quite well.”

“It was a tricky situation because sometimes he was quite stable and it felt like he could get out on his own, but he could (deteriorate) once again,” she said. “Luckily he didn’t lose any consciousness and he saw the situation through.”

Around 190 experts from Bulgaria, Croatia, Hungary, Italy, Poland and Turkey took part in the rescue, including doctors, paramedics and experienced cavers. Teams comprised of a doctor and three to four other rescuers took turns staying by his side at all times.

Zador said she had been involved in cave rescues before but Dickey’s rescue was the “longest” she experienced.

Dickey said after his rescue that he had started to throw up large quantities of blood inside the cave.

“My consciousness started to get harder to hold on to, and I reached the point where I thought ‘I’m not going to live,'” he told reporters.

A statement from the Mersin governor’s office said Dickey’s “general health” condition was “good”, without providing further details.

The Italian National Alpine and Speleological Corps said the rescue operation took more than 100 rescuers from around 10 counties a total of 60 hours. “Mark Dickey was in the cave for roughly 500 hours,” it said.

British scientist Ian Wilmut, whose research was central to the creation of the cloned animal, Dolly the Sheep, has died at the age of 79, the University of Edinburgh said on Monday.  

His death on Sunday, years after being diagnosed with Parkinson’s disease, was announced by the University of Edinburgh, where he worked. 

Wilmut, along with Keith Campbell from the Roslin animal sciences research institute in Scotland, generated news headlines and heated ethical debates in 1996 when they created Dolly, the first mammal to be cloned from an adult cell. 

“He led efforts to develop cloning, or nuclear transfer, techniques that could be used to make genetically modified sheep. It was these efforts which led to the births of Megan and Morag in 1995 and Dolly in 1996,” the university said in a statement. 

Dolly, named after country singer Dolly Parton, was the first mammal to be cloned from an adult cell, using a process called somatic cell nuclear transfer (SCNT). 

This involved taking a sheep egg, removing its DNA and replacing it with DNA from a frozen udder cell of a sheep that died years before. The egg was then zapped with electricity to make it grow like a fertilized embryo. No sperm were involved. 

Dolly’s creation triggered fears of human reproductive cloning, or producing genetic copies of living or dead people, but mainstream scientists have ruled this out as far too dangerous. 

Wilmut, who was born near Stratford-upon-Avon, attended the University of Nottingham, initially to study agriculture, before switching to animal science.  

He moved to the University of Edinburgh in 2005, received a knighthood in 2008 and retired from the university in 2012.

The U.S. approved updated COVID-19 vaccines Monday, hoping to rev up protection against the latest coronavirus strains and blunt any surge this fall and winter.

The Food and Drug Administration decision opens the newest shots from Moderna and Pfizer and its partner BioNTech to most Americans even if they’ve never had a coronavirus vaccination. It’s part of a shift to treat fall updates of the COVID-19 vaccine much like getting a yearly flu shot.

There’s still another step: The Centers for Disease Control and Prevention must sign off. A CDC advisory panel is set to issue recommendations Tuesday on who most needs the updated shots. Vaccinations could begin later this week, and both the COVID-19 and flu shot can be given at the same visit.

COVID-19 hospitalizations have been rising since late summer although – thanks to some lasting immunity from prior vaccinations and infections – not nearly as much as this time last year.

But protection wanes over time and the coronavirus continually churns out new variants that can dodge prior immunity. It’s been a year since the last time the vaccines were tweaked.

Just like earlier vaccinations, the fall round is cleared for adults and children as young as age 6 months. FDA said starting at age 5, most people can get a single dose even if they’ve never had a prior COVID-19 shot.

Younger children might need additional doses depending on their history of COVID-19 infections and vaccinations.

The newest shots target an omicron variant named XBB.1.5. That specific strain is no longer dominant but it’s close enough to coronavirus strains causing most COVID-19 illnesses today that FDA determined it would offer good cross-protection.

These newest shots replace combination vaccines that mixed protection against the original coronavirus strain and even older omicron variants.

Like earlier versions, they’re expected to be most protective against severe illness, hospitalization and death, rather than mild infection.

It’s lunchtime at the Salt Lake City Mosquito Abatement District and a colony of sabethes cyaneus — also known as the paddle-legged beauty for its feathery appendages and iridescent coloring — find their way to Ella Branham.

“They’re not very aggressive and they’re kind of picky eaters,” said Branham, a technician, as she exhaled into a glass tank to attract the insects to the carbon dioxide in her breath. “So I’ll be feeding them with my arm.”

Branham had volunteered to let the South American mosquitoes feed on her blood so they can produce eggs and maintain the colony for education and research at the lab in the Salt Lake City district. It’s one of the many mosquito control districts around the United States that seek to hold in check one of the world’s deadliest animals — one well-positioned to thrive as climate change fosters a warmer and wetter environment.

Mosquitoes can carry viruses including dengue, yellow fever, chikungunya and Zika. They are especially threatening to public health in Asia and Africa but are also closely monitored in the United States. Local agencies reported more than 1,100 cases of West Nile virus in 2022, according to the U.S. Centers for Disease Control and Prevention.

Most humans who contract West Nile show no symptoms. But for some, it can cause vomiting, fever and in rare cases seizures or meningitis. Over roughly the last 25 years, nearly 3,000 deaths and more than 25,000 hospitalizations linked to West Nile were reported throughout the United States — most of them in August.

West Nile deaths have been reported this year in states including Texas and Colorado, and mosquitoes are thought to be the source of “locally acquired” malaria infections of people in Maryland, Florida and Texas.

Ary Faraji, an entomologist and the executive director of the Salt Lake City mosquito abatement district, said monitoring shows the mosquito season starting earlier and lasting longer as the climate has warmed. The district used to historically shut down each year in mid-September, but that has gotten later and later. Last year, district workers were still setting and checking traps until Thanksgiving.

And this year — where an abnormally snowy winter and a very rainy spring left more water across the landscape for mosquitoes to breed in — his staff estimated that there were five times as many mosquitoes in May compared to the average year.

That’s where the health threat comes in. While both males and females feed on sugar or nectar throughout their lives, females require blood meals to nourish and develop their eggs.

“They are the true vixens,” Faraji said. “Some can be so beautiful and yet some can be so deadly.”

Faraji’s staff — made up of scientists and college and doctoral students — traps, sorts and tests mosquitos for viruses using drones, boats and ATVs. Their work takes into account how trends ranging from weather patterns to population growth will affect disease transmission.

“The more people you put in a closer vicinity of where the mosquitos are, the higher chance of pathogen transmission,” he said, noting the challenges of the wetland areas surrounding Utah’s Great Salt Lake.

Though dangerous, mosquitoes are also critical to ecosystems throughout the world, with various species serving as pollinators or food sources to fish, birds and frogs.

“We try to maintain a balance and suppress them to the point that they’re not negatively affecting communities,” Faraji said. “Taking them away would definitely negatively impact our ecosystem overall.”

The death toll from flash floods that have inundated central Greece due to Storm Daniel has risen to 12 with the number expected to rise. The clean-up task in the Thessaly area comes as health officials warn of infectious diseases that are breaking out as a result of dead livestock scattered across devastated sections.

Hara Petropoulou pleas for assistance after Storm Daniel caused widespread flooding in central Greece.

“Help,” she shouts to the anchor of a Sunday morning show. “Please help.”

“We may have survived the floods that drowned our towns and homes… but the stench of decomposing animal carcasses …. Our chickens, our goats, rabbits and sheep… It is horrific and it is going to kill us,” she adds.

The wife of a farmer in the farming heartland of Greece, Petropoulou says she is left with no other option than to clean up the debris herself.

“I have a bottle of chlorine in my hand… and I’m ready to head out into a meter of mud and floodwaters to clear out our chicken coop and to drag away the dead sheep the storm left behind.”

“I have no other choice,” she says.

Petropoulou is not alone. Thousands of other farmers are following suit.

But that is exactly what health authorities are warning against.

Dysentery, diphtheria, and malaria are just some of the infectious diseases resulting from the floods that ravaged Thessaly, the farming heartland of Greece, and livestock for much of the past week.

On Sunday, state health and veterinary officials said they had deployed dozens of special crews to collect dead livestock, taking decomposing carcasses to special incinerators to be burned.

But with dozens of villages and hamlets still stranded … all devoid of clean water and sewage, fears of further outbreaks grow.

“Authorities alone have been tasked with the cleanup of dead livestock,” said Deputy Health Minister Irini Agapidakishe on public television.

“People have to stay away from dead livestock, and those that have survived… Goats, chicken, sheep, cows even their pets have to be steered clear and away from contaminated fields.”

“The repercussions,” she said, “will be terrible.”

The looming health crisis adds to Daniel’s destruction after walls of water pounded the Thessaly plain. Officials say over a four-day period, the storm drenched the affected areas with more rainfall than London sees in a full year.

On Sunday, Prime Minister Kyriakos Mitsotakis toured the region to inspect recovery operations. He was expected to announce unprecedented aid measures in a late-night address.

Locals though want more. They say the biggest but most pressing challenge is to rebuild the region to fortify it against future natural disasters and climate change.

Mosquito-borne dengue fever is taking a heavy toll on South Asian nations this year as Bangladesh grapples with record deaths and Nepal faces cases in new areas, with disease experts linking worsening outbreaks to the impacts of climate change.

Authorities in the two countries are scrambling to contain and treat the disease – which is also known as “breakbone fever” for the severe muscle and joint pains it induces. Entomologists and epidemiologists say rising temperatures and longer monsoon seasons are providing ideal breeding conditions for mosquitoes.

The threat is not restricted to South Asia as dengue rates are rising globally with 4.2 million cases reported in 2022 — up eightfold from 2000 — the World Health Organization (WHO) says. Earlier this year, WHO said dengue is the fastest-spreading tropical disease worldwide and represents a “pandemic threat.”

In Bangladesh, at least 691 people have died so far in 2023, and more than 138,000 have been infected, official figures show, making this the deadliest year since the first recorded epidemic in 2000. The previous record toll was 281 deaths last year.

A lack of proper prevention measures has allowed the dengue-carrying Aedes aegypti mosquito to spread across almost all of Bangladesh, said Kabirul Bashar, an entomologist and zoology professor at Jahangirnagar University in the capital of Dhaka.

He said this raised the risk of more infections occurring during September. Dengue is common during the June-to-September monsoon season, when mosquitoes thrive in stagnant water.

“This climate is favorable for the breeding of Aedes mosquitoes,” Bashar said in an interview. “Dengue is not only a problem for Dhaka, it is now a problem for the entire country.”

Nepal struggling

Meanwhile, Nepal — which first recorded dengue in 2004 — has had at least 13 dengue deaths and more than 21,200 cases so far this year across 75 of its 77 districts, according to officials.

This year could match the 2022 toll of 88 deaths and 54,000 cases, said Uttam Koirala, a senior public health officer at the national epidemiology and disease control division.

Meghnath Dhimal, a senior research officer at the Nepal Health Research Council (NHRC), said the incidence and spread of dengue had been rising quickly nationwide in recent years.

Rising temperatures mean cases have started occurring in colder autumn months, while Nepal’s higher mountain districts that never before had the disease are now struggling to curb its spread, he said, describing the shifting patterns as “strange.”

For example, the city of Dharan in the mountainous east has been hit particularly hard this year — with dengue cases rising so fast that hospitals and ambulances are overwhelmed by demand, according to Umesh Mehta, the local health division chief.

The city of more than 160,000 people saw the number of dengue cases peak at 1,700 a day as of late August, he said.

Amrit Kumar Thakur, a Dharan resident, was one of four members of his family to contract dengue last month. The 27-year-old said the disease started with a mild body ache and got steadily worse before he was treated at a temporary health center set up to deal with the fast-growing number of cases.

“Dengue was the worst health experience of my life,” said Thakur, adding that he and his relatives had fully recovered.

Ideal conditions

WHO says dengue is rising partly because global warming benefits mosquitoes, along with other factors including movement of people and goods, urbanization and problems with sanitation.

In July, WHO said an unusual episodic amount of rainfall in Bangladesh, together with high temperatures and high humidity, had helped the mosquito population to grow across the nation.

Furthermore, Bangladesh has experienced longer-than-usual monsoon seasons in recent years, with erratic rainfall over the March-to-October period and more breeding grounds popping up for mosquitoes, according to various disease and health experts.

The number of potential breeding sites identified in 2023 is the highest in the last five years, said Nazmul Islam, director of the disease control branch of Bangladesh’s health department.

Fiercer floods fueled by heavy rains and melting glaciers — driven by climate change — are another major factor behind the spread of dengue, said Mohammad Mushtuq Husain, an adviser at the Institute of Epidemiology, Disease Control and Research.

The Bangladeshi government has also cited climate change as a driver behind the country’s worsening dengue outbreak.

Saber Hossain Chowdhury, the prime minister’s special envoy on climate change, said last month on the messaging platform X, formerly known as Twitter, that the nation’s record dengue cases are “a clear instance of (the) climate change health nexus.”

Bangladesh needs to think about a national plan for adapting its health system to prevent diseases like dengue from turning into major disasters, Chowdhury said in an interview.

Informing the public

As dengue lacks a specific cure, health experts say the disease must be kept at bay through control of mosquito breeding, engaging with the public, and managing symptoms.

In Dhaka, officials are going around the city spraying insecticide to kill mosquitoes and imposing fines on people if breeding sites for the larvae are found.

Atiqul Islam, mayor of the Dhaka North City Corporation, said the authorities would have to keep informing residents of the risks, and monitoring the situation, throughout the year.

“It’s not the time for pinning blame, rather everyone should come forward to deal with the dengue situation — for their love of this city where we are born, live and die,” said Islam.

In Nepal, Dhimal from the NHRC said no authority alone could stop dengue as mosquitoes are found everywhere from garages to the corners of houses which are out of reach of the government.

“Everyone should be aware and proactive and contribute from their side to control the spread of the vector,” he added.

Civil society and development organizations are also helping to tackle the disease.

Sanjeev Kafley, head of the Bangladesh delegation for the International Red Cross, said it was helping to raise public awareness, procuring testing kits, and boosting the availability of platelets used in blood transfusions to treat some patients.

Yet when it comes to treatment broadly, ordinary families face high costs. Researchers from Dhaka University’s Institute of Health Economics have warned that total medical expenses for dengue patients may exceed $91 million this year, up from $41 million in 2019.

Dhaka resident Akhtar Hossain spent $545 on private hospital care for his daughter, Ayesha Tabassum Taqwa, who ultimately died of dengue last month at the age of 10.

Hossain cried as he spoke of Taqwa’s love of learning.

“Her books, notebooks … are all still on the reading table. (She) will never arrange new books,” he said. “(But) who can we blame and what is the point of talking about it?”

Hurricane Lee is rewriting old rules of meteorology, leaving experts astonished at how rapidly it grew into a goliath Category 5 hurricane.

Lee could also be a dreadful harbinger of what is to come as ocean temperatures climb, spawning fast-growing major hurricanes that could threaten communities farther north and farther inland, experts say.

“Hurricanes are getting stronger at higher latitudes,” said Marshall Shepherd, director of the University of Georgia’s Atmospheric Sciences Program and a past president of the American Meteorological Society. “If that trend continues, that brings into play places like Washington, D.C., New York and Boston.”

Hyper-intensification

As the oceans warm, they act as jet fuel for hurricanes.

“That extra heat comes back to manifest itself at some point, and one of the ways it does is through stronger hurricanes,” Shepherd said.

During the overnight hours on Thursday, Lee shattered the standard for what meteorologists call rapid intensification — when a hurricane’s sustained winds increase by 56 kph in 24 hours.

“This one increased by 80 mph (129 kph),” Shepherd said. “I can’t emphasize this enough — we used to have this metric of 35 mph (56 kph), and here’s a storm that did twice that amount and we’re seeing that happen more frequently,” said Shepherd, who describes what happened with Lee as “hyper-intensification.”

With super-warm ocean temperatures and low wind shear, “all the stars were aligned for it to intensify rapidly,” said Kerry Emanuel, professor emeritus of atmospheric science at the Massachusetts Institute of Technology.

Inland threats

Category 5 status — when sustained winds are at least 253 kph — is quite rare. Only about 4.5% of named storms in the Atlantic Ocean have grown to a Category 5 in the past decade, said Brian McNoldy, a scientist and hurricane researcher at the University of Miami.

More intense major hurricanes are also threatening communities farther inland, since the monster storms can grow so powerful that they remain dangerous hurricanes for longer distances over land.

“I think that’s a story that’s kind of under-told,” Shepherd said. “As these storms are strong coming to landfall, in some cases they’re moving fast enough that they’re still hurricanes well inland.”

Hurricane Idalia was the latest example, when it came ashore in the Florida Panhandle last month and remained a hurricane as it entered south Georgia.

It then slammed into the Georgia city of Valdosta more than 116 kilometers away from where it made landfall. At least 80 homes in the Valdosta area were destroyed and hundreds of others damaged.

In 2018, Hurricane Michael carved a similar path of inland destruction, tearing up cotton crops and pecan trees and leaving widespread damage across south Georgia.

Risk for New England

While it’s too early to know how close Lee might come to the U.S. East Coast, New Englanders are keeping a wary eye on the storm as some models have projected it tracking perilously close to New England – particularly Maine. It has been 69 years since a major hurricane made landfall in New England, McNoldy said.

On Sept. 8, 1869, a Category 3 hurricane known as “the September Gale of 1869” struck Rhode Island, the National Weather Service in Boston noted Friday. The storm cut all telegraph lines between Boston and New York and capsized a schooner, killing 11 crew members.

“If Lee actually does make landfall in New England, there’s no doubt the storm surge would be a huge threat,” he said.

Monster waves

As Lee roils the ocean as it creeps closer to the eastern coast of the U.S., it could bring high seas and rip currents all up and down the eastern seaboard.

“What we are going to see from Lee — and we’re very confident — is it’s going to be a major wave producer,” Mike Brennan, director of the National Hurricane Center, said in a Friday briefing.

“This morning the highest significant wave height we were analyzing in Lee was between 45 and 50 feet (13.7 and 15 meters), and the highest waves could even be double that,” Brennan said. “So we could be looking at 80-, 90-foot (24-, 27-meter) waves associated with Lee.”

Emanuel was tracking the storm this weekend in New Harbor, Maine. Since it has been so long for any type of hurricane warning in New England, some residents might be complacent and think that hurricanes are a Florida or Louisiana problem, he said.

“One worries whether they’re going to take it seriously when it comes to that,” he said.

Something to watch

Forecasters will be watching any possible interaction in coming days between Lee and newly formed Tropical Storm Margot, which is expected to become a hurricane next week.

It’s possible that Margot could alter Lee’s path, though it’s too soon to know whether that will happen, experts say.

Margot is far to the east of Lee, but as Margot strengthens it could affect the weather systems in the region that steer hurricanes.

A phenomenon known as the Fujiwhara Effect can occur when two tropical storms rotate around each other, but that doesn’t mean they will in this case, Emanuel said. If it does happen, though, the two storms could push each other around in the Atlantic, which could alter their paths.

Novak Djokovic considers his mental state just as important as his physical condition when it comes to being prepared to play his best at age 36.

“Mentally there is probably a lot more that I’m dealing with in my private life than was the case 10 years ago. But that’s the beauty of life. Things are evolving, moving on,” said Djokovic, who will try to take another step toward what would be a 24th Grand Slam title when he faces Ben Shelton in the U.S. Open semifinals Friday.

“I just feel that there is always, I guess, an extra gear that you have inside of you and you can find when you dig deep to handle and manage energy levels, on and off the court,” Djokovic said, “if you’re really devoted to that and if you care about it, if you pay attention to that mental aspect as much as physical, of course.”

By the time players arrive at Flushing Meadows for the last major tournament of a long season — one that began in late December and will carry on into November — the ailments and injuries that are part of any professional athlete’s existence can make things tough. Some competing at the U.S. Open, which concludes this weekend, say the wear and tear on the mind can be just as hard to deal with as whatever might be wrong with one’s body.

“We’re already smashed. Completely,” said Daria Kasatkina, a 26-year-old from Russia who reached the fourth round in New York.

Stress comes from a variety of sources. The desire to win each match, of course. The importance of earning, and defending, rankings points. The fact that there is no annual salary in a sport where every competitor is an independent contractor who needs to pay for travel expenses and, in most cases, a personal coach, physiotherapist and other members of their “team.”

“At a Slam, tension is always there. A few days before it’s starting, you’re already feeling it. … You have to accept it and, maybe even round by round, it’s getting worse and worse,” said Kasatkina, a 2022 French Open semifinalist. “It’s part of the game. It’s part of this show. And we’re all in the same situation, all the players.”

U.S. Davis Cup captain Bob Bryan, who won 16 Grand Slam doubles titles with his twin, Mike, recalls how that would set in for some in Flushing Meadows.

And he recalls how it could alter on-court performance.

“There’s times where you just get out there and mentally you just can’t push because you’re so exhausted. And you don’t deal with the adversity well. Your thoughts turn negative, and you’re not opportunistic and optimistic on the court. And that will definitely affect your game,” Bryan said. “There’s a lot of players that never figured that out during their career. A lot of great champions and a lot of Hall of Famers ran out of gas here in New York.”

Not everyone deals with mental fatigue — or, if they do, acknowledges it.

“Physically, mentally, I feel ready,” Aryna Sabalenka, who will play Coco Gauff in the women’s final Saturday, said before the start of the U.S. Open. “I feel motivated. I feel strong.”

Professional athletes offering frank thoughts on mental health is still a relatively recent development. A tennis player, Naomi Osaka, was one of the first stars to come forward and discuss feelings of anxiety and depression, doing so after withdrawing from the 2021 French Open.

She didn’t set out to change perceptions on the topic or encourage others to seek help.

“It was a little selfish,” Osaka said Wednesday at the U.S. Open, where she participated with retired Olympic swimmer Michael Phelps in a panel discussion about mental health in sports. “I wasn’t thinking about everyone else, to be 100% honest.”

But she did help spur the discourse.

“For quite a few years, actually, mental training was not really talked about much, generally, in the tennis world. And mental health is a subject that is quite talked about in the last, I would say, three, four years, which I’m glad. It needs to be out there,” Djokovic said.

“It needs to be addressed in a proper way, so that the players have proper understanding of what they are going through and then have help and guidance, necessary guidance, for them to overcome certain obstacles,” he said. “Because in the end of the day, we are also people that have to deal with the private issues that everyone has.”

The ways players try to cope differs.

Some travel with a sports psychologist, for example.

Some make sure to manage their schedule to figure out when it’s possible to get a bit of a breather.

Some just accept that there aren’t many opportunities to recharge.

“The season is so long that there are so many ups and downs,” said 2021 U.S. Open champion Daniil Medvedev, who faces defending champion Carlos Alcaraz on Friday. “You just keep going, keep playing. I don’t think I have been on vacation in the offseason for three years. … You just try to manage this physical and mental fatigue the best you can with experience, and usually I feel like I’m doing this not too bad.”

SpaceX must take a series of steps before it can launch its mega rocket again after its debut ended in an explosion, federal regulators said Friday.

The Federal Aviation Administration said it closed its investigation into SpaceX’s failed debut of Starship, the world’s biggest rocket. The agency is requiring SpaceX to take 63 corrective actions and to apply for a modified FAA license before launching again.

FAA official said multiple problems led to the April launch explosion, which sent pieces of concrete and metal hurtling for thousands of feet (meters) and created a plume of pulverized concrete that spread for miles (kilometers) around.

SpaceX founder Elon Musk said in the accident’s aftermath that he improved the 394-foot (120-meter) rocket and strengthened the launch pad. A new Starship is on the redesigned pad, awaiting liftoff. It will fly empty, as before.

During the initial test flight, the rocketship had to be destroyed after it tumbled out of control shortly after liftoff from Boca Chica Beach. The wreckage crashed into the Gulf of Mexico. SpaceX said fuel leaks during ascent caused fires to erupt at the tail of the rocket, severing connection with the main flight computer and leading to a loss of control.

That flight “provided numerous lessons learned,” the company said in a statement.

NASA wants to use Starship to land astronauts back on the moon in another few years. Musk’s ultimate goal is to build a fleet of Starships to carry people and supplies to Mars.

More than a decade after a tsunami destroyed the Fukushima Daiichi Nuclear Power Station on Japan’s Pacific coast, the country has begun releasing the treated wastewater that has been accumulating on the site of the disaster, sparking anger in the region despite assurances by scientists that the process will not be harmful to the environment.

The water being released into the Pacific has been largely decontaminated of most dangerous elements, but contains small amounts of tritium, a radioactive isotope of hydrogen that cannot be extracted through any existing treatment method.

Water releases began in late August and will continue sporadically for decades as Japan works to reduce the amount of treated water on the site of the power plant. That water is currently stored in more than 800 tanks. Japanese officials say that it is necessary to drain and remove some of the tanks so that facilities necessary for the decommissioning of the plant can be built.

Japanese officials have gone to great lengths to demonstrate their confidence in the safety of the water surrounding Fukushima. Prime Minister Fumio Kishida appeared on television eating sashimi prepared from fish caught in the area after the water releases began.

Despite such displays, as well as assessments from experts, including the International Atomic Energy Agency, that the release of water will not cause harm to the environment, protests have arisen.

Japan and South Korea have been the sites of large demonstrations against the release. The Chinese government has been among the most vocal critics, accusing Japan of behaving irresponsibly and imposing a ban on the importation of Japanese seafood.

2011 disaster

The Fukushima power plant was devastated in 2011, after an earthquake off the coast of Japan generated a massive tidal wave that swept ashore on the east coast of Honshu Island, killing some 20,000 people and inundating entire cities. The wave disabled the systems that the plant used to keep nuclear fuel rods cool, resulting in a catastrophic meltdown of one of its reactors and the release of dangerous amounts of radiation.

The Japanese government was forced to evacuate tens of thousands of residents from the region and has been working ever since to mitigate the damage and prevent further contamination.

That process has involved an ongoing effort to keep the plant’s fuel rods cool, using seawater. The process causes the water to be contaminated by a number of radioactive elements. The water is retained on site and treated by what is known as the Advanced Liquid Processing System (ALPS), which removes almost all contaminants, with the exception of tritium.

Nuclear experts measure the amount of tritium present in a substance using units called becquerels. According to the World Health Organization, water containing up to 10,000 becquerels of tritium per liter is considered safe to drink. The treated water discharged from the Fukushima plant is being diluted to the point that it contains approximately 190 becquerels of tritium per liter.

Other countries release tritium

Japan is not the only country to release water containing tritium into oceans and rivers. Many nations that rely on nuclear power for some of their energy supply similarly release treated wastewater.

Despite its criticism of Japan’s actions at Fukushima, at least four Chinese nuclear power plants also release water containing tritium into the ocean, all of them at significantly greater concentrations than in Fukushima.

Over the length of the plan, Japan expects 22 trillion becquerels of tritium per year to be released. According to data released by the Japanese government, China’s Qinshan Phase III Nuclear Power Plant in Zhejiang province released 143 trillion becquerels of tritium in 2020. Last year, the report said, China’s Yangjiang Nuclear Power Station in Guangdong province released 121 trillion, while two other plants released 102 trillion and 90 trillion, respectively.

Other countries with nuclear power plants that release tritium include South Korea, France, Russia, Canada, the United Kingdom and the United States.

There is no clear evidence that tritium-containing water has caused environmental damage or posed a danger to humans or wildlife in the areas where it has been released, in some cases for decades.

China’s opposition

The Chinese government has taken a very public stand against the Fukushima water releases, despite engaging in the same practice itself.

A statement released by the Chinese Foreign Ministry said, in part, “The ocean is the common property of all humanity, and forcibly starting the discharge of Fukushima’s nuclear wastewater into the ocean is an extremely selfish and irresponsible act that ignores international public interests.”

Criticism from Beijing has resulted in a concerted effort on the part of many Chinese citizens to bombard Japanese government agencies and businesses with abusive phone calls. In some cases, the near-constant barrage of calls has made it difficult for some businesses to conduct their normal operations.

Shihoko Goto, acting director of the Asia program at the Wilson Center, a Washington-based think tank, told VOA that China’s decision to focus so intently on the Fukushima water release is meant to demonstrate the significant “economic leverage” it has over Japan.

“It makes clear that Japan and the Japanese economy … [are] incredibly dependent on China,” she said.

The controversy has also served as a distraction at a time when the Chinese economy is stumbling badly.

“That’s been standard practice in China in the past. When things are going well, they don’t necessarily see the need to lash out,” she said. “But given the current circumstances, it’s certainly a way for China to distract from the real issues.”

Goto said it also demonstrates that “Chinese economic coercion is not going to be limited to small countries. It’s also prepared to go against the world’s third-largest economy.”

Chinese scientists have succeeded in growing kidneys containing human cells in pig embryos, a world first that could one day help address organ donation shortages.  

 

But the finding, published Thursday in a study in the journal Cell Stem Cell, raises ethical issues — especially since some human cells also were found in the pigs’ brains, experts said. 

 

The researchers from the Guangzhou Institutes of Biomedicine and Health focused on kidneys since they are the most commonly transplanted in human medicine. 

 

“Rat organs have been produced in mice, and mouse organs have been produced in rats, but previous attempts to grow human organs in pigs have not succeeded,” senior author Liangxue Lai said in a statement. 

 

“Our approach improves the integration of human cells into recipient tissues and allows us to grow human organs in pigs.” 

 

This is a different approach to the recent high-profile breakthroughs in the United States, where genetically modified pig kidneys and even a heart have been placed inside humans. 

 

The new research paper “describes pioneering steps in a new approach to organ bioengineering using pigs as incubators for growing and cultivating human organs,” said Dusko Ilic, a professor of stem cell sciences at King’s College London who was not involved in the research. 

 

Ilic cautioned there would be many challenges to turning the experiment into a viable solution, but “nevertheless, this captivating strategy warrants further exploration.” 

 

Gene editing 

 

A major challenge in creating such hybrids has been that pig cells outcompete human cells.

To overcome the obstacles, the team used CRISPR gene editing to delete two genes essential for kidneys to form inside a pig embryo, creating what’s called a “niche.”

They then added specially prepared human pluripotent stem cells — cells that have the potential to develop into any cell type — that filled the niche. 

 

Before implanting the embryos in sows, they grew them in test tubes containing substances that nourished both the human and pig cells. 

 

In total, they transferred 1,820 embryos into 13 surrogate mothers. The pregnancies were terminated at 25 and 28 days to assess how the experiment had worked. 

 

Five embryos selected for analysis were found to have functionally normal kidneys for their stage of development. They contained between 50 and 60 percent human cells. 

 

“We found that if you create a niche in the pig embryo, then the human cells naturally go into these spaces,” said co-author Zhen Dai. 

 

“We saw only very few human neural cells in the brain and spinal cord and no human cells in the genital ridge.” 

 

But the presence of any human cells in the pig brains raises concerns, said Darius Widera, a professor of stem cell biology at England’s University of Reading. 

 

“Although this approach is a clear milestone and the first successful attempt to grow whole organs containing human cells in pigs, the proportion of human cells in the generated kidneys is still not high enough,” he said. 

 

In the long run, the team wants to optimize its technology for use in human transplantation but admits it’s not ready yet. 

 

An important limitation was the kidneys had pig-derived vascular cells, which could cause rejection if transplanted into a human. 

 

Nevertheless, the team is already working on growing other human organs in pigs, such as the heart and pancreas.

Hurricane Lee whirled through open waters on Thursday as forecasters warned it could become the first Category 5 storm of the Atlantic season. 

Lee was not expected to make landfall while on a projected path that will take it near the northeast Caribbean, although forecasters said tropical storm conditions were possible on some islands. Meteorologists said it was too early to provide details on potential rainfall and wind gusts. 

The Category 4 hurricane was about 1,260 kilometers east of the northern Leeward Islands. It had winds of up to 215 kilometers per hour and was moving west-northwest at 24 kph. 

The storm was expected to grow even more powerful late Thursday and remain a major hurricane into next week. 

“Lee continues to strengthen at an exceptional rate,” the National Hurricane Center said. 

U.S. President Joe Biden on Thursday was given the hurricane’s latest trajectory and details of preparations underway by the U.S. Federal Emergency Management Agency, which deployed unidentified assets to Puerto Rico and the U.S. Virgin Islands, according to the White House. 

Life-threatening surf was expected to hit the Lesser Antilles on Friday and reach the British and U.S. Virgin Islands, Puerto Rico, Hispaniola, the Bahamas and Bermuda this weekend, the center said. 

“We will see waves between 10 and 15 feet [3 and 5 meters], so we don’t want anyone on the beaches,” said Ernesto Morales with the National Weather Service in San Juan, Puerto Rico. 

The National Hurricane Center said dangerous surf and rip currents were forecast for most of the U.S. East Coast starting Sunday. 

Lee is the 12th named storm of the Atlantic hurricane season, which runs from June 1 to November 30 and peaks in September. 

Tropical Storm Margot became the 13th named storm after forming on Thursday evening. It was about 465 kilometers west-northwest of the Cabo Verde Islands. It had winds of up to 65 kph and was forecast to strengthen into a hurricane over the weekend. It was moving west-northwest at 28 kph and was expected to remain over open water. 

The National Oceanic and Atmospheric Administration in August forecast 14 to 21 named storms this season, with six to 11 of them expected to become hurricanes, and of those, two to five possibly developing into major hurricanes. 

In the Pacific, Hurricane Jova churned through open waters far from Mexico’s southwest coast as a Category 4 storm. It posed no threat to land. 

It was about 965 kilometers southwest of the southern tip of Baja California, and was moving west-northwest at 28 kph with winds up to 230 kph. The storm was expected to weaken starting late Thursday.

Earth has sweltered through its hottest Northern Hemisphere summer ever measured, with a record warm August capping a season of brutal and deadly temperatures, according to the World Meteorological Organization.

Last month was not only the hottest August scientists ever recorded by far with modern equipment, it was also the second hottest month measured, behind only July 2023, WMO and the European climate service Copernicus announced Wednesday.

August was about 1.5 degrees Celsius warmer than pre-industrial averages. That is the threshold that the world is trying not to pass, though scientists are more concerned about rises in temperatures over decades, not merely a blip over a month’s time.

The world’s oceans — more than 70% of the Earth’s surface — were the hottest ever recorded, nearly 21 C, and have set high temperature marks for three consecutive months, the WMO and Copernicus said.

“The dog days of summer are not just barking, they are biting,” United Nations Secretary-General Antonio Guterres said in a statement. “Climate breakdown has begun.”

So far, 2023 is the second hottest year on record, behind 2016, according to Copernicus.

Scientists blame ever warming human-caused climate change from the burning of coal, oil and natural gas with an extra push from a natural El Nino, which is a temporary warming of parts of the Pacific Ocean that changes weather worldwide. Usually an El Nino, which started earlier this year, adds extra heat to global temperatures but more so in its second year.

Climatologist Andrew Weaver said the numbers announced by WMO and Copernicus come as no surprise, bemoaning how governments have not appeared to take the issue of global warming seriously enough. He expressed concern that the public will just forget the issue when temperatures fall again.

“It’s time for global leaders to start telling the truth,” said Weaver, a professor at the School of Earth and Ocean Sciences at the University of Victoria in Canada. “We will not limit warming to 1.5 C; we will not limit warming to 2.0 C. It’s all hands on deck now to prevent 3.0 C global warming — a level of warming that will wreak havoc worldwide.”

Copernicus, a division of the European Union’s space program, has records going back to 1940, but in the United Kingdom and the United States, global records go back to the mid-1800s and those weather and science agencies are expected to soon report that the summer was a record-breaker.

“What we are observing, not only new extremes but the persistence of these record-breaking conditions, and the impacts these have on both people and planet, are a clear consequence of the warming of the climate system,” Copernicus Climate Change Service Director Carlo Buontempo said.

Scientists have used tree rings, ice cores and other proxies to estimate that temperatures are now warmer than they have been in about 120,000 years. The world has been warmer before, but that was before human civilization, seas were much higher and the poles were not icy.

So far, daily September temperatures are higher than what has been recorded before for this time of year, according to the University of Maine’s Climate Reanalyzer.

While the world’s air and oceans were setting records for heat, Antarctica continued to set records for low amounts of sea ice, the WMO said.

“Antarctic sea ice extent was literally off the charts, and the global sea surface temperature was once again at a new record,” WMO’s secretary-general, Petteri Taalas, said in a statement released to the media. “It is worth noting that this is happening BEFORE we see the full warming impact of the El Nino event, which typically plays out in the second year after it develops.”

A strong El Nino coincided with the all-time high temperatures in 2016. The U.N. weather agency earlier this year rolled out predictions that suggest Earth would within the next five years have a year that averages 1.5 degrees Celsius warmer than in the mid-19th century. Each year at or near 1.5 matters.

It also predicted 98% chance of breaking the 2016 record between now and 2027.

The new readings on high global temperatures came as WMO released Wednesday its latest bulletin on air quality and climate, noting that extreme heat, compounded by wildfires and desert dust, has had a measurable impact on air quality, human health and the environment.

WMO scientific adviser Lorenzo Labrador lamented the deteriorating air quality around the globe and cited “record-breaking wildfire season” in many parts of the world, including western Canada and Europe.

“If heat waves increase as a result of El Nino, we may probably expect a further degradation in air quality as a whole,” he said.
