Doctors Without Borders said Sunday that there is a suspected outbreak of measles in an internal displacement camp in Sudan. The international humanitarian organization said 13 children have died recently in the suspected outbreak at the camp in Sudan’s White Nile state. “We are receiving sick children with suspected measles every day, most with complications,” the organization posted in a tweet. A steady stream of people is coming to the camp as they flee the fighting between the country’s two warring factions. Doctors Without Borders has two clinics in White Nile. The organization says it had over 3,000 patients in June and needs to “increase assistance, scale up services like vaccinations, nutritional support, shelter, water and sanitation.” …

The head of the U.N.’s Food and Agriculture Organization, Qu Dongyu, was re-elected Sunday for a second term as head of the U.N. agency. He was the only candidate standing for the role of FAO director-general and received 168 out of 182 votes in a ballot in Rome on Sunday. Qu, a former Chinese government minister who was nominated for the post by Beijing, will serve a new four-year term from August 1. His appointment is seen as a part of a drive by Beijing to get more Chinese figures into senior jobs at international bodies. Qu, a biologist by training, was vice-minister of agriculture before taking over as head of the U.N. agency in 2019. FAO directors can hold the role for a maximum of two consecutive terms. The vote came during the FAO Conference, which runs until July 7. …

NAIROBI, Kenya — Nowhere in the world has a higher rate of unsafe abortions or unintended pregnancies than sub-Saharan Africa, where women often face scorn for becoming pregnant before marriage. Efforts to legalize and make abortions safer in Africa were shaken when the U.S. Supreme Court ended the national right to an abortion a year ago. Within days, Sierra Leone President Julius Maada Bio declared that his government would decriminalize abortion “at a time when sexual and reproductive health rights for women are being either overturned or threatened.” But some U.S.-based organizations active in Africa were emboldened, especially in largely Christian countries. One is Family Watch International, a nonprofit Christian conservative organization whose anti-LGBTQ+ stance, anti-abortion activities and “intense focus on Africa” led to its designation as a hate group by the Southern Poverty Law Center. In April, Family Watch International helped to develop a “family values and sovereignty” meeting at Uganda’s presidential offices with lawmakers and other delegates from more than 20 African countries. The organization’s Africa director also is advocating for his country, Ethiopia, to revoke a 2005 law that expanded abortion access and dramatically reduced maternal mortality. “It’s kind of like the gloves are off,” Sarah Shaw, head of advocacy at U.K.-based MSI Reproductive Choices, an international provider of reproductive health services, said in an interview. In a September speech to the African Bar Association, the president of Family Watch International, Sharon Slater, alleged that donor countries were attempting a “sexual social recolonization of Africa” by smuggling …

The only break much of America can hope for soon from eye-watering, dangerous smoke from fire-struck Canada would be brief bouts of shirt-soaking, sweltering heat and humidity from a deadly, Southern heat wave, forecasters say. And then the smoke will likely return to the Midwest and East. Here’s why: Neither the 235 out-of-control Canadian wildfires nor the weather pattern that’s responsible for this mess of meteorological maladies are showing signs of relenting for the next week or longer, according to meteorologists at the National Oceanic and Atmospheric Administration’s Weather Prediction Center. First, the weather pattern made abnormally hot and dry conditions for Canada to burn at off-the-chart record levels. Then it created a setup where the only relief comes when low pressure systems roll through, which means areas on one side get smoky air from the north and the other gets sweltering air from the south. Smoke or heat. “Pick your poison,” said prediction center forecast operations chief Greg Carbin. “The conditions are not going to be very favorable. “As long as those fires keep burning up there, that’s going to be a problem for us,” Carbin said. “As long as there’s something to burn, there will be smoke we have to deal with.” Take St. Louis. The city had two days of unhealthy air Tuesday and Wednesday, but for Thursday “they’ll get an improvement of air quality with the very hot and humid heat,” said weather prediction center meteorologist Bryan Jackson. The forecast is for temperatures that feel like …

Researchers say they are detecting a dramatic spike in ocean surface temperatures around the world — reaching as much as 5 degrees Celsius (9 degrees Fahrenheit) above normal in the North Atlantic — and they could rise even higher. “It is very alarming, and as temperatures keep spiking, this is not unexpected,” said Kim Cobb, a climate scientist and professor of earth, environmental and planetary sciences at Brown University in Rhode Island. As the oceans get warmer each year, scientists say they are triggering chaotic weather patterns around the world, including torrential downpours and intense heat waves that cause flooding and severe drought. Climate scientists attribute much of the warming to so-called greenhouse gases and say that to prevent the most severe consequences, the use of fossil fuels must be cut in half by 2030. The most recent increase has caused the most extreme ocean heat wave in the British Isles in 170 years, according to the Met Office, the United Kingdom’s national weather service. “This is an off-the-charts heat wave in the oceans,” said John Abraham, a climate change scientist at the University of St. Thomas in Minnesota. “The temperatures we are seeing this year are a remarkable excursion from normal temperatures.” Oceans, which cover 70% of the Earth, have a huge impact on weather. “When the air blows over the oceans, the air warms up and gets more humid and that drives storms,” Abraham told VOA. “The water vapor amplifies warming by trapping outgoing radiation from escaping and …

Elon Musk announced Saturday that Twitter would temporarily restrict how many tweets users could read per day, in a move meant to tamp down on the use of the site’s data by artificial intelligence companies.  The platform is limiting verified accounts to reading 6,000 tweets a day. Non-verified users — the free accounts that make up the majority of users — are limited to reading 600 tweets per day.   New unverified accounts would be limited to 300 tweets.  The decision was made “to address extreme levels of data scraping” and “system manipulation” by third-party platforms, Musk said in a tweet Saturday afternoon, as some users quickly hit their limits.  “Goodbye Twitter” was a trending topic in the United States following Musk’s announcement.  Twitter would soon raise the ceiling to 8,000 tweets per day for verified accounts, 800 for unverified accounts and 400 for new unverified accounts, Musk said.  Twitter’s billionaire owner did not give a timeline for how long the measures would be in place.   The day before, Musk had announced that it would no longer be possible to read tweets on the site without an account.  Much of the data scraping was coming from firms using it to build their AI models, Musk said, to the point that it was causing traffic issues with the site.  In creating AI that can respond in a human-like capacity, many companies feed them examples of real-life conversations from social media sites.  “Several hundred organizations (maybe more) were scraping Twitter data extremely aggressively, …

Need Plan B? Tap your credit card and enter B6.  Since last November, a library at the University of Washington has featured a different kind of vending machine, one that’s become more popular on campuses around the country since the U.S. Supreme Court ended constitutional protections for abortion last year. It’s stocked with ibuprofen, pregnancy tests and the morning-after pill.  With some states enacting abortion bans and others enshrining protections and expanding access to birth control, the machines are part of a push on college campuses to ensure emergency contraceptives are cheap, discreet and widely available.  There are now 39 universities in 17 states with emergency contraceptive vending machines, and at least 20 more considering them, according to the American Society for Emergency Contraception. Some, such as the University of Tulsa in Oklahoma, are in states where abortion is largely banned.  Over-the-counter purchase of Plan B and generic forms is legal in all 50 states.  The 2022 ruling overturning Roe v. Wade “is putting people’s lives at stake, so it makes pregnancy prevention all the more urgent,” said Kelly Cleland, the ASEC’s executive director. “If you live in a state where you cannot get an abortion and you can’t get an abortion anywhere near you, the stakes are so much higher than they’ve ever been before.”  Washington this year became first U.S. state to set aside money — $200,000 to fund $10,000 grants that colleges can obtain next year through an application process — to expand access to emergency contraceptives …

WASHINGTON – Long time, no speak: NASA has re-established contact with the intrepid Ingenuity Mars Helicopter after more than two months of radio silence, the space agency said Friday.  The mini rotorcraft, which hitched a ride to the Red Planet with the Perseverance rover in early 2021, has survived well beyond its initial 30-day mission to prove the feasibility of its technology in five test flights.  Since then, it has been deployed dozens of times, acting as an aerial scout to assist its wheeled companion in searching for signs of ancient microbial life from billions of years ago, when Mars was much wetter and warmer than today.   Ingenuity’s 52nd flight launched on April 26, but mission controllers at NASA’s Jet Propulsion Laboratory (JPL) in California lost contact as it descended to the surface following its two minute, 1,191-foot (363-meter) hop.  The loss of communications was expected, because a hill stood between Ingenuity and Perseverance, which acts as a relay between the drone and Earth.   Nonetheless, “this has been the longest we’ve gone without hearing from Ingenuity so far in the mission,” Joshua Anderson, Ingenuity team lead at JPL, told AFP.  “Ingenuity is designed to take care of itself when communication gaps like this occur, but we all still had a sense of relief finally hearing back.”  Data so far indicate that the helicopter is in good shape. If further health checks also come back normal, Ingenuity will be all set for its next flight, westward toward a rocky outcrop …

Heat waves like the one that engulfed parts of parts of the South and Midwest and killed more than a dozen people are becoming more common, and experts say the extreme weather events, which claim more lives than hurricanes and tornados, will likely increase in the future. A heat dome that pressured the Texas power grid and killed 13 people there and another in Louisiana pushed eastward Thursday and was expected to be centered over the mid-South by the weekend. Heat index levels of up to 112 degrees (44 Celsius) were forecast in parts of Florida over the next few days. Eleven of the heat-related deaths in Texas occurred in Webb County, which includes Laredo. The dead ranged in age from 60 to 80 years old, and many had other health conditions, according to the county medical examiner. The other two fatalities were Florida residents who died while hiking in extreme heat at Big Bend National Park. Scientists and medical experts say such deaths caused by extreme heat will only increase in the U.S. each summer without more action to combat climate change that has pushed up temperatures, making people especially vulnerable in areas unaccustomed to warm weather. “Here in Boston we prepare for snowstorms. Now we need to learn how to prepare for heat,” said Dr. Gaurab Basu, a primary care physician and the director of education and policy at the Center for Climate, Health, and the Global Environment at Harvard T.H. Chan School of Public Health. Planting more …

SYDNEY – Australia on Saturday will become one of the first countries to recognize psychedelic drugs as medicines. In February, the Therapeutic Goods Administration, Australia’s medical regulator, sanctioned use of psychedelics for some mental health conditions. Experts agree that psychedelic-assisted therapies in Australia are in their infancy. Starting Saturday, authorized psychiatrists in Australia will be able to prescribe methylenedioxy methamphetamine – MDMA, the active ingredient in such party drugs as ecstasy or molly — to treat post-traumatic stress disorder. They will also be allowed to prescribe psilocybin, a compound found in psychotropic “magic” mushrooms, to treat depression that has not responded to other therapies. Susan Rossell, a cognitive neuropsychologist at Swinburne University in Melbourne, is conducting one of Australia’s biggest clinical trials of psilocybin. Preliminary results show significant improvements in some patients’ mental health while others have shown no signs of getting better. Rossell told the Australian Broadcasting Corp. that psychedelic therapies research is still in its early stages. “We have been stuck for very many years in terms of mental health treatments for people with treatment-resistant conditions,” she said. “So, the fact that psychedelic medicines do seem to be working for a number of people is fantastic. However, they are not working for some people as well, and that is where I would note a great deal of caution in this field at the moment.” The Royal Australian and New Zealand College of Psychiatrists has issued new guidelines for its members’ use of psychedelic drugs. They must only be …

ALBUQUERQUE, NEW MEXICO — A team of Italian researchers reached the edge of space Thursday morning, flying aboard Virgin Galactic’s rocket-powered plane as the company prepares for monthly commercial flights. The flight launched from Spaceport America in the New Mexico desert, with two Italian Air Force officers and an engineer with the National Research Council of Italy focusing on a series of microgravity experiments during their few minutes of weightless. One wore a special suit that measured biometric data and physiological responses while another conducted tests using sensors to track heart rate, brain function and other metrics while in microgravity. The third studied how certain liquids and solids mix in that very weak gravity. Virgin Galactic livestreamed the flight on its website, showing the moment when the ship released from its carrier plane and the rocket was ignited. The entire trip took about 90 minutes, with the plane’s touchdown on the runway prompting cheers and claps by Virgin Galactic staff. With the ship’s copilots, it marked the most Italians in space at the same time. Colonel Walter Villadei, a space engineer with the Italian Air Force, celebrated by unfolding an Italian flag while weightless. Next up for Virgin Galactic will be the first of hundreds of ticket holders, many who have been waiting years for their chance at weightlessness and to see the curvature of the Earth. Those commercial flights are expected to begin in August and will be scheduled monthly, the space tourism company said. Virgin Galactic has been …

LONDON – One of the world’s most common artificial sweeteners is set to be declared a possible carcinogen next month by a leading global health body, according to two sources with knowledge of the process, pitting it against the food industry and regulators. Aspartame, used in products from Coca-Cola diet sodas to Mars’ Extra chewing gum and some Snapple drinks, will be listed in July as “possibly carcinogenic to humans” for the first time by the International Agency for Research on Cancer (IARC), the World Health Organization’s (WHO) cancer research arm, the sources said. The IARC ruling, finalized earlier this month after a meeting of the group’s external experts, is intended to assess whether something is a potential hazard or not, based on all the published evidence. It does not take into account how much of a product a person can safely consume. This advice for individuals comes from a separate WHO expert committee on food additives, known as JECFA (the Joint WHO and Food and Agriculture Organization’s Expert Committee on Food Additives), alongside determinations from national regulators. However, similar IARC rulings in the past for different substances have raised concerns among consumers about their use, led to lawsuits, and pressured manufacturers to recreate recipes and swap to alternatives. That has led to criticism that the IARC’s assessments can be confusing to the public. JECFA, the WHO committee on additives, is also reviewing aspartame use this year. Its meeting began at the end of June, and it is due to …

Geoffrey Hinton, one of the so-called godfathers of artificial intelligence, on Wednesday urged governments to step in and make sure that machines do not take control of society. Hinton made headlines in May when he announced he had quit Google after a decade of work to speak more freely on the dangers of AI, shortly after the release of ChatGPT captured the imagination of the world. The highly respected AI scientist, who is based at the University of Toronto, was speaking to a packed audience at the Collision tech conference in the Canadian city. The conference brought together more than 30,000 startup founders, investors and tech workers, most looking to learn how to ride the AI wave and not hear a lesson on its dangers. “Before AI is smarter than us, I think the people developing it should be encouraged to put a lot of work into understanding how it might try and take control away,” Hinton said. “Right now there are 99 very smart people trying to make AI better and one very smart person trying to figure out how to stop it taking over and maybe you want to be more balanced,” he said. AI could deepen inequality, says Hinton Hinton warned that the risks of AI should be taken seriously despite his critics who believe he is overplaying the risks. “I think it’s important that people understand that this is not science fiction, this is not just fearmongering,” he insisted. “It is a real risk that we …

WASHINGTON – City parks and green spaces help counter heat, boost biodiversity and instill a sense of calm in the urban jungle – and they also help slow biological aging, a study found. People who have access to green spaces were found to be on average 2.5 years biologically younger than those who do not, according to the study, published Wednesday in Science Advances. “Living near more greenness can help you be younger than your actual age,” Kyeezu Kim, the study’s lead author and a postdoctoral scholar at Northwestern University’s Feinberg School of Medicine, told AFP. “We believe our findings have significant implications for urban planning in terms of expanding green infrastructure to promote public health and reduce health disparities.” Exposure to green spaces has previously been linked with better cardiovascular health and lower rates of mortality. It’s thought that more physical activity and social interactions are at play, but whether parks actually slowed down aging on a cellular level has been unclear. To investigate, the team behind the study examined DNA chemical modifications known as methylation. Prior work has shown that so-called epigenetic clocks based on DNA methylation can be a good predictor of health conditions such as cardiovascular disease, cancer and cognitive function, and are a more accurate way of measuring age than calendar years. Kim and colleagues followed more than 900 white and Black people from four American cities — Birmingham, Alabama; Chicago; Minneapolis; and Oakland, California — from 1986 to 2006. Using satellite imaging, the team …

TERRA CEIA ISLAND, FLORIDA — The Florida Health Department has issued a statewide mosquito-borne illness advisory after four locally contracted cases of malaria were reported along the Gulf Coast south of Tampa.  On Monday, a health alert issued by the federal Centers for Disease Control and Prevention also noted that another case had been detected in Texas, marking the first time there has been a local spread of malaria in the United States in 20 years.  The four residents in Sarasota County received treatment and have recovered, according to the state’s Health Department advisory. Malaria, caused by a parasite that spreads through bites from Anopheles mosquitoes, causes fever, chills, sweating, nausea and vomiting, and headaches. It is not spread person to person.  It’s the threat of the mosquito-borne illness that concerns Kathleen Gibson-Dee, who lives on Terra Ceia Island, which is about 32 kilometers north of Sarasota County.  Even though no malaria cases have been reported in Manatee County, where Terra Ceia is located, Gibson-Dee said that she’s now routinely using bug repellent while working in her garden.  “I don’t go out without it,” she told The Associated Press on Tuesday. “And we don’t go out in the evening because you can see clouds and clouds of bugs now. They may not all be mosquitoes, but there’s certainly mosquitos out there.”  Another resident, Tom Lyons, says news of the malaria cases “makes me take mosquito protection a little more seriously.”  The mosquito population thrives in Terra Ceia because “it’s an …

South Korea is changing the way it calculates a person’s age.  Under a new law that takes effect Wednesday, South Korea is adopting the international method that uses a person’s actual date of birth to determine their age.    Under its traditional method, South Koreans are considered to be one year old at birth, including their months in the womb, and become a year older every January 1 regardless of their actual date of birth.  The new law that takes effect Wednesday means all South Koreans will officially become a year or two younger.    Officials say a separate method of calculation that uses the date a person is born and then adds a year each January 1 will remain in effect for compulsory military service, education and the legal drinking age.  Some information for this report came from Reuters, Agence France-Presse.   …

A dangerous and prolonged heat wave blanketed large parts of the southern United States on Tuesday, buckling highways and forcing people to shelter indoors in what scientists called a climate-change supercharged event.  Excessive heat warnings were in place from Arizona in the southwest to Alabama in the southeast, with south and central Texas and the Lower Mississippi Valley worst hit, the National Weather Service said.  Victor Hugo Martinez, a 57-year-old foreman who was leading workers repairing a road in Houston, told AFP: “We can’t keep up with it. It’s too much, we have like 10 or 12 spots like this right now.”  The crew wrapped bandanas around their heads to protect themselves from the blazing heat, with Martinez explaining they made sure to drink plenty of water and take several breaks to protect their health.  The National Weather Service meanwhile urged Americans in across the South to drink water, stay indoors, and check on vulnerable friends and relatives.  Andrew Pershing, a scientist with Climate Central, told AFP the “really unusual thing about this event is how big it is, and how long it has lasted.”  “There have been places in Texas that have had more than two weeks of over 100 degrees Fahrenheit, which are just really unusual temperatures for this time of year even in a region that is used to heat.”  Extreme weather more likely Accumulated historic greenhouse emissions made the extreme weather event at least five times more likely than otherwise, according to preliminary calculations by a …

The number of different electronic cigarette devices sold in the U.S. has nearly tripled to over 9,000 since 2020, driven almost entirely by a wave of unauthorized disposable vapes from China, according to tightly controlled sales data obtained by The Associated Press. The numbers demonstrate the Food and Drug Administration’s inability to control the tumultuous vaping market more than three years after declaring a crackdown on kid-friendly flavors. Most disposables e-cigarettes, which are thrown away when they’re used up, come in sweet, fruity flavors like pink lemonade, gummy bear and watermelon that have made them the favorite tobacco product among teenagers. All of them are technically illegal because they haven’t been authorized by the FDA. Once a niche market, cheaper disposables made up 40% of the roughly $7 billion retail market for e-cigarettes last year, according to data from analytics firm IRI obtained by the AP. The company’s proprietary data collects barcode scanner sales from convenience stores, gas stations and other retailers. More than 5,800 unique disposable products are now being sold in numerous flavors and formulations, according to IRI’s data, up 1,500% from 365 in early 2020. That’s when the FDA effectively banned all flavors except menthol and tobacco from cartridge-based e-cigarettes like Juul, the rechargeable device blamed for sparking a nationwide surge in underage vaping. But the FDA’s policy — formulated under President Donald Trump — excluded disposables, prompting many teens to switch from Juul to the newer flavored products. “The FDA moves at a ponderous pace and …

Deforestation rates are near record lows in Indonesia, home to the world’s third-largest rainforests. It’s one of the few bright spots in an otherwise grim annual report, on the loss of forests worldwide, from the environmental research and policy group World Resources Institute. Overall, the world lost 4.1 million hectares of undisturbed tropical forest last year, an area the size of Switzerland, according to WRI. That’s a 10% increase from 2021. The loss of forest released as much planet-warming carbon dioxide as all the fossil fuels burned in India in 2021. Deforestation reverses the CO2 removal function that trees perform. It raises local temperatures and disrupts rainfall patterns. World leaders pledged to end deforestation by the end of the decade during climate negotiations in Glasgow in 2021. “Are we on track to halt deforestation by 2030? The short answer is a simple no,” Rod Taylor, head of WRI’s forests program, told reporters at a news conference announcing the results. Deforestation rates The good news from Indonesia is that government moratoriums on logging and palm oil plantations and increased fire prevention measures have kept forest losses low. Corporate pledges to end deforestation in the palm oil supply chain also appear to be working, WRI says. The 230,000 hectares of untouched, primary forest lost last year is a sharp decline from the 2016 peak of 930,000 hectares. Still, “that’s a pretty big loss,” Arie Rompas, head of the forest campaign for Greenpeace Indonesia, told VOA. “The area lost is about three times …

Which is the longest river in the world, the Nile or the Amazon? The question has fueled a heated debate for years. Now, an expedition into the South American jungle aims to settle it for good.    Using boats run on solar energy and pedal power, an international team of explorers plans to set off in April 2024 to the source of the Amazon in the Peruvian Andes, then travel nearly 7,000 kilometers (4,350 miles) across Colombia and Brazil, to the massive river’s mouth on the Atlantic. “The main objective is to map the river and document the biodiversity” of the surrounding ecosystems, the project’s coordinator, Brazilian explorer Yuri Sanada, told AFP.    The team also plans to make a documentary on the expedition.    Around 10 people are known to have traveled the full length of the Amazon in the past, but none have done it with those objectives, said Sanada, who runs film production company Aventuras (Adventures) with his wife, Vera.  Decades-old dispute The Amazon, the pulsing aorta of the world’s biggest rainforest, has long been recognized as the largest river in the world by volume, discharging more than the Nile, the Yangtze and the Mississippi combined.  But there is a decades-old geographical dispute over whether it or the Nile is longer, made murkier by methodological issues and a lack of consensus on a very basic question: where the Amazon starts and ends.  The Guinness Book of World Records awards the title to the African river. But “which is the longer …

Muhammad Ali Pate, a Harvard professor who has held top health jobs in Nigeria, has relinquished the top job at the Gavi global vaccine alliance, the organization announced Monday. Pate, a medical doctor trained in internal medicine and infectious disease, was due to assume the helm on August 3, Gavi had announced in February, taking over from U.S. medical epidemiologist Seth Berkley, who had been in charge since 2011. Pate informed Gavi “that he has taken an incredibly difficult decision to accept a request to return and contribute to his home country, Nigeria,” the statement said, without further details about the decision. Gavi’s Chief Operating Officer David Marlow will instead assume the position of Interim Chief Executive Officer while a search for a new CEO continues. The Gavi vaccine alliance is a nonprofit organization created in 2000 to provide an array of vaccines to developing countries. Gavi says that since its inception, it has provided vaccines to more than 981 million children, “and prevented more than 16.2 million future deaths, helping to halve child mortality in 73 lower-income countries.” Gavi has taken the lead on the COVAX initiative, alongside the World Health Organization and the Coalition for Epidemic Preparedness Innovations. The global scheme has so far shipped nearly 1.9 billion COVID-19 vaccines to 146 territories, with the focus on providing donor-funded jabs to the 92 weakest economies. …
