It was once Latin America’s largest landfill. Now, a decade after Rio de Janeiro shut it down and redoubled efforts to recover the surrounding expanse of highly polluted swamp, crabs, snails, fish and birds are once again populating the mangrove forest.

“If we didn’t say this used to be a landfill, people would think it’s a farm. The only thing missing is cattle,” jokes Elias Gouveia, an engineer with Comlurb, the city’s garbage collection agency that is shepherding the plantation project. “This is an environmental lesson that we must learn from: Nature is remarkable. If we don’t pollute nature, it heals itself.”

Gouveia, who has worked with Comlurb for 38 years, witnessed the Gramacho landfill recovery project’s timid first steps in the late 1990s.

The former landfill is located right by the 148 square miles (383 square kilometers) Guanabara Bay. Between the landfill’s inauguration in 1968 and 1996, some 80 million tons of garbage were dumped in the area, polluting the bay and surrounding rivers with trash and runoff.

In 1996, the city began implementing measures to limit the levels of pollution in the landfill, starting with treating some of the leachate, the toxic byproduct of mountains of rotting trash. But garbage continued to pile up until 2012, when the city finally shut it down.

“When I got there, the mangrove was almost completely devastated, due to the leachate, which had been released for a long time, and the garbage that arrived from Guanabara Bay,” recalled Mario Moscatelli, a biologist hired by the city in 1997 to assist officials in the ambitious undertaking.

The bay was once home to a thriving artisanal fishing industry and popular palm-lined beaches. But it has since become a dump for waste from shipyards and two commercial ports. At low tide, household trash, including old washing machines and soggy couches, float atop vast islands of accumulated sewage and sediment.

The landfill, where mountains of trash once attracted hundreds of pickers, was gradually covered with clay. Comlurb employees started removing garbage, building a rainwater drainage system, and replanting mangroves, an ecosystem that has proved particularly resilient — and successful — in similar environmental recovery projects.

Mangroves are of particular interest for environmental restoration for their capacity to capture and store large amounts of planet-warming carbon dioxide, Gouveia explained.

Experts say mangroves can bury even more carbon in the sediment than a tropical rainforest, making it a great tool to fight climate change.

To help preserve the rejuvenated mangrove from the trash coming from nearby communities, where residents sometimes throw garbage into the rivers, the city used clay from the swamp to build a network of fences. To this day, Comlurb employees continue to maintain and strengthen the fences, which are regularly damaged by trespassers looking for crabs.

Leachate still leaks from the now-covered landfill, which Comlurb is collecting and treating in one of its wastewater stations.

Comlurb and its private partner, Statled Brasil, have successfully recovered some 60 hectares, an area six times bigger than what they started with in the late 1990s.

“We have turned things around,” Gouveia said. “Before, [the landfill] was polluting the bay and the rivers. Now, it is the bay and the rivers that are polluting us.”

SEATTLE — In 2016, hospitals in New York state identified a rare and dangerous fungal infection never before found in the United States. Research laboratories quickly mobilized to review historical specimens and found the fungus had been present in the country since at least 2013.

In the years since, New York City has emerged as ground zero for Candida auris infections. And until 2021, the state recorded the most confirmed cases in the country year after year, even as the illness has spread to other places, according to Centers for Disease Control and Prevention data analyzed by The Associated Press.

Candida auris is a globally emerging public health threat that can cause severe illness, including bloodstream, wound and respiratory infections. Its mortality rate has been estimated at 30% to 60%, and it’s a particular risk in health care settings for people with serious medical problems.

Last year, the most cases were found in Nevada and California, but the fungus was identified clinically in patients in 29 states. New York state remains a major hot spot.

A prominent theory for the sudden explosion of Candida auris, which was not found in humans anywhere until 2009, is climate change.

Humans and other mammals have warmer body temperatures than most fungal pathogens can tolerate, so they have historically been protected from most infections. However, rising temperatures can allow fungi to develop tolerance to warmer environments, and over time humans may lose resistance. Some researchers think this is what is happening with Candida auris.

When Candida auris was first spreading, said Meghan Marie Lyman, a CDC medical epidemiologist for the mycotic diseases branch, the cases were linked to people who had traveled to the U.S. from other places. Now, most cases are acquired locally — generally spreading among patients in health care settings.

In the U.S., there were 2,377 confirmed clinical cases diagnosed last year — an increase of more than 1,200% since 2017. But Candida auris is becoming a global problem. In Europe, a survey last year found case numbers nearly doubled from 2020 to 2021.

“The number of cases has increased, but also the geographic distribution has increased,” Lyman said. She noted that while screenings and surveillance have improved, the skyrocketing case numbers reflect a true increase.

In March, a CDC press release noted the seriousness of the problem, citing the pathogen’s resistance to traditional antifungal treatments and the alarming rate of its spread. Public health agencies are focused primarily on strategies to urgently mitigate transmission in health care settings.

Dr. Luis Ostrosky, a professor of infectious diseases at McGovern Medical School at UTHealth Houston, thinks Candida auris is “kind of our nightmare scenario.”

“It’s a potentially multidrug resistant pathogen with the ability to spread very efficiently in health care settings,” he said. “We’ve never had a pathogen like this in the fungal infection area.”

Ostrosky has treated about 10 patients with the fungal infection but has consulted on many more. He said he has seen it spread through an entire ICU in two weeks.

The fungus poses a significant threat to human health, researchers say.

Immunocompromised patients in hospitals are most at risk, but so are people in long-term care centers and nursing homes, which generally have less access to diagnostics and infection control experts.

Candida auris is not only challenging to treat, but also difficult to diagnose. It is rare and many clinicians are not aware it exists.

Beyond the increase in cases, popular culture has helped increase awareness of fungal infections. A popular HBO series, The Last of Us, is a drama about the survivors of a fungal outbreak.

“I think the way to think about how global warming is putting selection pressure on microbes is to think about how many more really hot days we are experiencing,” said Arturo Casadevall, a microbiologist, immunologist and professor at Johns Hopkins University. “Each day at (37.7 degrees Celsius) provides a selection event for all microbes affected — and the more days when high temperatures are experienced, the greater probability that some will adapt and survive.”

CAPE CANAVERAL, Fla. — The cosmos is offering up a double feature in August: a pair of supermoons culminating in a rare blue moon.

Catch the first show Tuesday evening as the full moon rises in the southeast, appearing slightly brighter and bigger than normal. That’s because it will be closer than usual, just 357,530 kilometers (222,159 miles) away, thus the supermoon label.

The moon will be even closer the night of Aug. 30 — a scant 357,344 kilometers (222,043 miles) distant. Because it’s the second full moon in the same month, it will be what’s called a blue moon.

“Warm summer nights are the ideal time to watch the full moon rise in the eastern sky within minutes of sunset. And it happens twice in August,” said retired NASA astrophysicist Fred Espenak, dubbed Mr. Eclipse for his eclipse-chasing expertise.

The last time two full supermoons graced the sky in the same month was in 2018. It won’t happen again until 2037, according to Italian astronomer Gianluca Masi, founder of the Virtual Telescope Project.

Masi will provide a live webcast of Tuesday evening’s supermoon as it rises over the Coliseum in Rome.

“My plans are to capture the beauty of this … hopefully bringing the emotion of the show to our viewers,” Masi said in an email. “The supermoon offers us a great opportunity to look up and discover the sky.”

This year’s first supermoon was in July. The fourth and last will be in September. The two in August will be closer than either of those.

Provided clear skies, binoculars or backyard telescopes can enhance the experience, Espenak said, revealing such features as lunar maria — the dark plains formed by ancient volcanic lava flows — and rays emanating from lunar craters.

According to the Old Farmer’s Almanac, the August full moon is traditionally known as the sturgeon moon. That’s because of the abundance of that fish in the Great Lakes in August  hundreds of years ago.

PHOENIX — By the time Aaliyah Ibarra started second grade, her family had moved five times in four years in search of stable housing. As she was about to start a new school, her mother, Bridget Ibarra, saw how much it was affecting her education.

At 8 years old, her daughter did not know the alphabet.

“She was in second grade and couldn’t tell me any of the letters. I would point them out and she didn’t know,” Bridget Ibarra said. “She would sing the song in order, but as soon as I mixed them up, she had no idea.”

“I just didn’t know what letters were which,” says Aaliyah, now 9. “I know them now.”

The family’s struggles coincided with the COVID-19 pandemic that forced Aaliyah to begin her school experience online. Unfamiliar with a computer, Aaliyah was regularly kicked out of the virtual classroom, her mother said. Teachers complained she was not looking at the screen and took too many breaks.

Zoom school was especially difficult for Aaliyah because she was homeless — and like thousands of students nationally, her school didn’t know.

Homeless students often fell through the cracks during the tumult of the pandemic, when many schools struggled to keep track of families with unstable housing. Not being identified as homeless meant students lost out on eligibility for crucial support such as transportation, free uniforms, laundry services and other help.

Years later, the effects have cascaded. As students nationwide have struggled to make up for missed learning, educators have lost critical time identifying who needs the most help. Schools are offering tutoring and counseling but now have limited time to spend federal pandemic relief money for homeless students, said Barbara Duffield, executive director of SchoolHouse Connection, a national homelessness organization.

“There is urgency because of the losses that have occurred over the pandemic — loss in learning, the gaps in attendance and the health crisis,” she said. Many education leaders, Duffield said, don’t even know about federal money earmarked for homeless students — and the programs expire next year.

The number of children identified as homeless by schools nationwide dropped by 21% from the 2018-19 school year to the 2020-21 school year, according to federal data. But the decrease, representing more than 288,000 students, likely includes many kids whose homelessness was unknown to schools. Federal counts of homeless people living on the street or in shelters also appeared to decrease in 2021 due to pandemic disruptions, but by 2022, those numbers shot up to the highest in a decade.

In Bridget Ibarra’s case, she chose not to tell the school her kids were homeless — and she says teachers, disconnected from students by a screen, never asked. She was worried if officials knew the family was staying in a shelter, and the school was obliged by law to provide transportation, the family would face pressure to enroll in a different school that was closer.

She knew how hard the disruptions were on her kids.

“I know they didn’t enjoy moving as often as we did. They would say things like, ‘We’re moving again? We just moved!'” Ibarra said.

“When I moved, I missed my friends and my teacher,” Aaliyah said.

The stigma and fear associated with homelessness also can lead families not to tell anyone they lack secure housing, Duffield said.

“If we don’t identify children proactively, we can’t ensure that they have everything they need to be successful in school and even go to school,” she said.

Before the pandemic, Ibarra and her two children moved in with her brother in Phoenix because she was having trouble making ends meet. Then her brother died unexpectedly. At the time, Ibarra was pregnant with her third child and couldn’t afford the rent with what she earned working at a fast-food restaurant.

The family spent the next six months at Maggie’s Place, a shelter in North Phoenix that caters to pregnant women. The four of them, including Aaliyah’s infant brother, moved next to Homeward Bound, an apartment-like shelter for families, where they were living when the pandemic hit a few months before Aaliyah started kindergarten.

Aaliyah’s school, David Crockett Elementary, stuck with online learning her entire kindergarten year. Aaliyah and her older brother, joined by several other children, spent most of their school days on computers in a mixed-grade makeshift classroom at the shelter.

“It was like she wasn’t even in school,” Ibarra said. 

While the shelter helped the family meet their basic needs, Ibarra said she asked the school repeatedly for extra academic help for her daughter. She blamed the struggles partly on online learning, but she also felt the school was giving all their attention to Aaliyah’s older brother because he already was designated as a special education student with an individualized education program, or IEP.

The principal, Sean Hannafin, said school officials met frequently with the children’s mom. He said they offered the support they had available, but it was hard to determine online which students had needs that required intervention.

“The best thing we could do was take that data and flag them for when we returned in person, because you need a certain amount of time to observe a child in a classroom,” he said. “The online setting is not the place to observe.”

A federal law aimed at ensuring homeless students have equal access to education provides rights and services to children without a “fixed, regular and adequate nighttime residence.”

Many students aren’t identified as homeless when their parents or guardians enroll them. At school, teachers, cafeteria staff, aides or bus drivers often notice other students whose well-being may need looking into. Students may have unwashed clothes, or many late arrivals or absences.

But with children learning online, teachers and staff often didn’t see those things.

Overall, the drop in the student homelessness count began before the pandemic, but it was much steeper in the first full school year after COVID-19 hit. The percentage of enrolled students identified as homeless in the U.S. dropped from 2.7% in 2018-19 to 2.2% in 2020-21.

Over that timeframe, Arizona had one of the biggest drops in the number of students identified as homeless, from about 21,000 to nearly 14,000. But there were signs many families were in distress. KateLynn Dean, who works at Homeward Bound, said the shelter saw huge numbers of families dealing with homelessness for the first time during the pandemic.

Eventually, Bridget Ibarra had to enroll Aaliyah in a different school.

After getting kicked out of low-income housing last year when their property owner sold the building, the family lived with Ibarra’s mother before finding another low-income unit in Chandler, more than 32 kilometers east of Phoenix.

Once the family moved, enrolling in school was far from easy. Aaliyah missed the first three weeks of the school year last fall because of delays obtaining transcripts, and Ibarra insisted she not start the year without a plan to address her delays in reading and writing. Aaliyah spent that time playing and sitting around the house.

“Honestly, Aaliyah said she didn’t care how long, because she didn’t want to go to that school anyway,” her mother said. She said Aaliyah missed her friends and was tired of moving.

At Aaliyah’s new school, Frye Elementary, Principal Alexis Cruz Freeman saw for herself how hard it was to keep in touch with families when children were not in classrooms. Several students disappeared altogether. But she said families have started reengaging with school. The state of Arizona reported more than 22,000 students were identified as homeless in the last school year — twice as many as the year before.

Ibarra said she tried to shield as much discomfort about their living situation from her kids as possible. It worked. Aaliyah doesn’t remember much about the places they’ve stayed except the people that surrounded her family.

Aaliyah has gained ground academically at her new school, Cruz Freeman said. She still has trouble pronouncing and recognizing some words. But by the end of the school year, she was able to read a text and write four sentences based on its meaning. She is also performing at grade level in math.

The principal considers her a success story in part because of her mother’s support.

“She was an advocate for her children, which is all that we can ever ask for,” Cruz Freeman said.

The EU is looking to prohibit chemicals deemed unsafe for children — especially ones that disrupt growth hormones — in imported toys under new rules proposed Friday by the European Commission.

China is overwhelmingly the biggest manufacturer of toys imported into the European Union, accounting for 83% of the value of toys brought in in 2021, according to the official EU statistics agency Eurostat.

“Enforcement will be stepped up thanks to digital technologies, allowing unsafe toys to be more easily detected, notably at EU borders,” EU internal market commissioner Thierry Breton said.

The commission’s proposed Toy Safety Regulation aims to address loopholes in existing EU legislation dating from 2009 that dictates safety standards in toys sold across the 27-nation bloc.

It also seeks to update the rules to better address online sales.

A commission statement emphasized that toys bought in the EU are “already among the safest ones in the world.”

But it said more needed to be done, given “the high number of unsafe toys that are still sold in the EU, especially online,” and particularly imported ones.

The proposed revision zeroes in on “chemicals that affect the endocrine system, and chemicals affecting the respiratory system or are toxic to a specific organ” in toys.

The endocrine system comprises glands that produce hormones. In children, chemicals that disrupt its normal operation can affect growth, thyroid functions and puberty, and contribute to diabetes or obesity.

To ensure that all toys sold in the European Union are safe, the commission is suggesting a requirement for importers to procure “digital product passports” that would assist in inspecting shipments.

The European Consumer Organisation (BEUC) strongly welcomed the commission’s initiative and noted that if it became EU law “it would be the first time ever — worldwide — that both known and suspected hormone-disrupting chemicals are banned from an entire product group.”

It said a consumer group’s test of babies’ teething toys in May found 11 out of 20 toys released such chemicals.

The head of the European Consumer Voice in Standardisation, Stephen Russell, said: “For years, we and BEUC have criticized the all-too-weak provision of toy safety legislation when it comes to chemicals.

“It is very welcome to see the European Commission now proposes to phase out hormone-disrupting chemicals from an entire product group.”

Arizona’s saguaro cacti, a symbol of the U.S. West, are leaning, losing arms and in some cases falling over during the state’s record streak of extreme heat, a scientist said on Tuesday.

Summer monsoon rains the cacti rely on have failed to arrive, testing the desert giants’ ability to survive in the wild as well as in cities after temperatures above 43 Celsius degrees (110 Fahrenheit) for 25 days in Phoenix, said Tania Hernandez.

“These plants are adapted to this heat, but at some point the heat needs to cool down and the water needs to come,” said Hernandez, a research scientist at Phoenix’s 140-acre (57-hectare) Desert Botanical Garden, which has over 2/3 of all cactus species, including saguaros which can grow to over 12 meters (40 feet).

Plant physiologists at the Phoenix garden are studying how much heat cacti can take. Until recently many thought the plants were perfectly adapted to high temperatures and drought. Arizona’s heat wave is testing those assumptions.

Cacti need to cool down at night or through rain and mist. If that does not happen they sustain internal damage. Plants now suffering from prolonged, excessive heat may take months or years to die, Hernandez said.

Cacti in Phoenix are being studied as the city is a heat island, mimicking higher temperatures plants in the wild are expected to face with future climate change, Hernandez said.

NEW YORK — More than 100,000 people in the U.S. have become allergic to red meat since 2010 because of a weird syndrome triggered by tick bites, according to a government report released Thursday. But health officials believe many more have the problem and don’t know it.

A second report estimated that as many as 450,000 Americans have developed the allergy. That would make it the 10th most common food allergy in the U.S., said Dr. Scott Commins, a University of North Carolina researcher who co-authored both papers published by the Centers for Disease Control and Prevention.

Health officials said they are not aware of any confirmed deaths, but people with the allergy have described it as bewildering and terrifying.

“I never connected it with any food because it was hours after eating,” said one patient, Bernadine Heller-Greenman.

The reaction, called alpha-gal syndrome, occurs when an infected person eats beef, pork, venison or other meat from mammals — or ingests milk, gelatin or other mammal products.

It’s not caused by a germ but by a sugar, alpha-gal, that is in meat from mammals — and in tick saliva. When the sugar enters the body through the skin, it triggers an immune response and can lead to a severe allergic reaction.

Scientists had seen reactions in patients taking a cancer drug that was made in mouse cells containing the alpha-gal sugar. But in 2011 researchers first reported that it could spread through tick bites, too.

They tied it to the lone star tick, which despite its Texas-themed name is most common in the eastern and southern U.S. (About 4% of all U.S. cases have been in the eastern end of New York’s Long Island.)

One of the studies released Thursday examined 2017-22 test results from the main U.S. commercial lab looking for alpha-gal antibodies. They noted the number of people testing positive rose from about 13,000 in 2017 to 19,000 in 2022.

Experts say cases may be up for a variety of reasons, including lone star ticks’ expanding range, more people coming into contact with the ticks or more doctors learning about it and ordering tests for it.

But many doctors are not. The second study was a survey last year of 1,500 U.S. primary care doctors and health professionals. The survey found nearly half had never heard of alpha-gal syndrome, and only 5% said they felt very confident they could diagnose it. Researchers used that information to estimate the number of people with the allergy — 450,000.

People with the syndrome can experience symptoms including hives, nausea, vomiting, diarrhea, severe stomach pain, difficulty breathing, dizziness and swelling of the lips, throat, tongue or eye lids. Unlike some other food allergies, which occur soon after eating, these reactions hit hours later.

Some patients have only stomach symptoms, and the American Gastroenterological Association says people with unexplained diarrhea, nausea and abdominal pain should be tested for the syndrome.

Doctors counsel people with the allergy to change their diet, carry epinephrine and avoid tick bites.

The allergy can fade away in some people — Commins has seen that happen in about 15% to 20% of his patients. But a key is avoiding being re-bitten.

“The tick bites are central to this. They perpetuate the allergy,” he said.

One of his patients is Heller-Greenman, a 78-year-old New York art historian who spends summers on Martha’s Vineyard. She has grown accustomed to getting bitten by ticks on the island and said she has had Lyme disease four times.

About five years ago, she started experiencing terrible, itchy hives on her back, torso and thighs in the middle of the night. Her doctors concluded it was an allergic reaction but couldn’t pinpoint the trigger.

She was never a big meat eater, but one day in January 2020 she had a hamburger and then a big, fatty steak the following evening. Six hours after dinner, she woke up nauseated, then suffered terrible spells of vomiting, diarrhea and dizziness. She passed out three times.

She was diagnosed with alpha-gal syndrome shortly after that and was told to avoid ticks and to stop eating red meat and dairy products. There have been no allergic reactions since.

“I have one grandchild that watches me like a hawk,” she said, making sure she reads packaged food labels and avoids foods that could trigger a reaction.

“I feel very lucky, really, that this has worked out for me,” she said. “Not all doctors are knowledgeable about this.”

A 20-year-old, U.S.-funded AIDS relief program that is credited with saving tens of millions of lives around the world may not be reauthorized if conservative and anti-abortion activists are successful in a campaign against it.

The President’s Emergency Plan for AIDS Relief (PEPFAR) was launched in 2003 by then-President George W. Bush, and since then it has channeled more than $110 billion in support for the fight against the AIDS epidemic in more than 50 countries around the world.

It has been particularly successful in Western and sub-Saharan Africa, where it helps provide antiretroviral medication to the more than 25 million people who are living with the disease.

The program received $6.9 billion in fiscal 2023. Through its history, the program has typically been reauthorized for five years at a time, in order to provide some certainty about the flow of relief dollars. It was last authorized in 2018. Advocates of the program are calling for a “clean” reauthorization that does not alter the program or introduce uncertainty about the flow of funds.

However, that reauthorization is now in doubt, as conservative lawmakers and activists have expressed concern that the program works with various organizations around the world that, in addition to combating AIDS, provide reproductive health services, including abortion.

‘Radical’ ideology

In a joint letter to key members of Congress this spring, dozens of anti-abortion groups urged lawmakers to reconsider their support for the program unless new rules are put in place that restrict the way it can spend federal funds.

“The American people do not support using taxpayer dollars to fund abortion at home or abroad,” the groups wrote. “For that reason, there exists long-standing precedent not to fund abortion, directly or indirectly, through U.S. foreign assistance. We are concerned that grants from the President’s Emergency Plan for AIDS Relief (PEPFAR) are used by nongovernmental organizations that promote abortions and push a radical gender ideology abroad.”

Failure to reauthorize the program would not necessarily kill it, because Congress could still appropriate money for it each year. But it would chip away at the administrative foundation of PEPFAR, leaving it less able to adapt to changing conditions in countries participating in the program, including changes in local laws that affect the provision of specific kinds of aid, and changes in the prevalence of the virus.

Pressuring lawmakers

Several influential conservative organizations, including the Heritage Foundation, Family Research Council and Susan B. Anthony (SBA) Pro-Life America, have said that they oppose a clean reauthorization of the program. They said they would add any vote that renewed the program without changes to their legislative scorecards.

Those scorecards, which track lawmakers’ adherence to the wishes of conservative activist organizations, are influential because a low score can leave a member of Congress open to a reelection challenge from a more conservative rival.

Autumn Christensen, vice president of public policy for SBA Pro-Life America, said in a statement emailed to VOA that her organization believes the Biden administration has “bowed to the pressures of the international abortion lobby and integrated broader sexual and reproductive services (which includes abortion) into their strategic plans.”

Christensen praised legislation proposed by Representative Mario Diaz-Balart, a Florida Republican, that would reauthorize PEPFAR for a single year and explicitly deny any funding to organizations that “promote or perform” abortions.

Mexico City policy

Those advocating for a clean reauthorization of PEPFAR point out that it is already illegal under U.S. law for foreign aid funds to be spent on the delivery of abortion services.

A 1973 provision of the Foreign Assistance Act, known as the Helms Amendment, reads, “[N]o foreign assistance funds may be used to pay for the performance of abortion as a method of family planning or to motivate or coerce any person to practice abortions.”

That language has, for generations, blocked direct funding of abortion with U.S. aid. However, it has not blocked U.S. aid programs from providing funds to organizations that provide access to abortions using funds from other sources.

Opponents of a clean PEPFAR reauthorization are demanding that stronger anti-abortion protections, such as the “Mexico City policy,” be incorporated into the program.

First adopted in 1983 by President Ronald Reagan’s administration, the policy bars U.S. aid from being disbursed to any organization that provides access to abortion services, even with non-U.S. money.

Since its original introduction, the Mexico City policy has been rescinded by every Democratic presidential administration upon taking office and has been reinstated by every Republican.

Former President Donald Trump not only reinstated the policy early in his presidency, but he strengthened it. By 2019, it was U.S. policy to refuse to provide funds to groups that even spoke in favor of abortion rights or supported other organizations that did.

President Joe Biden reversed Trump’s reinstatement of the policy when he took office in 2021.

Known impacts

Matthew Kavanagh is the director of the Global Health Policy and Politics Initiative at Georgetown Law School’s O’Neill Institute for National and Global Health Law. He told VOA that the impact of the Mexico City policy is already well-known to public health researchers.

“PEPFAR is one of the most successful and impactful global health programs in the world’s history,” Kavanagh said. But when the Trump administration reinstated the Mexico City policy, “quite a few organizations actually dropped out from being PEPFAR recipients,” he said.

Kavanagh said that many of the organizations that are most experienced at providing the kind of interventions that made PEPFAR successful are local family planning organizations that offer a range of services and counseling, often including abortion.

“Local family planning organizations were no longer allowed to provide HIV prevention programming and to receive PEPFAR funding, and that was a huge loss for the program,” he said.

He also warned against plans to reauthorize the program for just one year, saying that doing so would create damaging uncertainty for organizations serving desperate people.

“Organizations around the world are depending on this for lifesaving programs,” Kavanagh said. “People are not put on HIV treatment for one year, and then taken off. People are on HIV treatment for their lives, and we need to ensure that these programs don’t have to worry that they’re going to be shut down at the end of the year.”

The Biden administration on Thursday announced the first cancer-focused initiative under its advanced health research agency. The goal is to help surgeons more easily differentiate between healthy tissue and cancerous cells.

The Precision Surgical Interventions program, which is being launched under the administration’s Advanced Research Projects Agency for Health, will aim to significantly improve cancer outcomes over the next few decades.

In a Thursday statement announcing the initiative, President Joe Biden called the investment “a major milestone in the fight to end cancer as we know it.” The initiative is part of Biden’s “cancer moonshot” initiative.

The hope is that the investment will help doctors develop tools that will remove all cancerous cells while avoiding healthy nerves and blood vessels.

Biden said he eventually wants the cancer death rate to be cut in half.

“Harnessing the power of innovation is essential to achieving our ambitious goal of turning more cancers from death sentences to treatable diseases and — in time — cutting the cancer death rate in half,” he said.

“As we’ve seen throughout our history, from developing vaccines to sequencing the genome, when the U.S. government invests in innovation, we can achieve breakthroughs that would otherwise be impossible, and save lives on a vast scale. ARPA-H follows in that tradition of bold, urgent innovation,” Biden said, using an acronym for his Advanced Research Projects Agency for Health initiative.

“What’s true is that many cancer treatments still start with surgery,” Arati Prabhakar, the director of the White House Office of Science and Technology, told The Associated Press. “So being really smart and attacking and developing new technology to make that first step better could really revolutionize how we are able to treat cancer for so many Americans.”

Formed in 2022, the Advanced Research Projects Agency for Health is modeled after the Defense Advanced Research Projects Agency, or DARPA. The military-focused agency played a central role in developing GPS and the internet.

The “cancer moonshot,” as well as the ARPA-H more broadly, are part of the Biden administration’s unity agenda, which “aims to bring people from both parties together to get big things done for the American people,” Biden said in the statement.

In September, ARPA-H will host an event in Chicago for interested researchers with the intent of quickly authorizing projects.

The World Health Organization on Thursday warned that health threats are surging as the war in Sudan escalates and millions of people, many sick and wounded, flee for safety within Sudan and across borders to neighboring countries where health services are fragile and hard to reach.

The war, which erupted April 15 between the Sudanese Armed Forces and paramilitary Rapid Support Forces, is not contained within the country but has profound regional implications.

The conflict has displaced an estimated 3.4 million people, including 2.5 million inside Sudan. Nearly 760,000 people have been forced to flee as refugees to six neighboring countries, with many people reportedly arriving in poor health, carrying infectious diseases and other afflictions.

The Federal Ministry of Health reports at least 1,136 people have been killed and more than 12,000 injured since the conflict began. “Of course, this is very underreported of the number of casualties,” said Nima Abid, World Health Organization representative in Sudan.

He said the scale of the health crisis triggered by the conflict in Sudan was enormous, noting that the fragile health system in Sudan was unable to cope with the multiple emergencies that exist as “two-thirds of the hospitals in the affected areas are not functional” and are unable to respond to the huge public health needs.

WHO has verified 51 attacks on health facilities since the conflict began, resulting in 10 deaths and 24 injuries and “cutting off access to urgently needed care.”

Abid said that “all the organizational activities have stalled; vector control activities have stalled. Currently, we have a large measles outbreak with more than 2,000 cases and 30 deaths.

“I mean, even before the war, the vaccination coverage was not high,” added Abid, noting that the Blue Nile and White Nile states were the most heavily affected. “So, now we have outbreaks affecting almost 10 states.”

Abid also said he was concerned that cases of malaria, dengue and rift valley fever will rise during the current rainy season, noting that “all these vector-borne diseases are endemic in Sudan” and control measures have stopped.

“We do have an outbreak of cholera in South Kordofan,” he said, “with more than 300 cases and seven deaths. So, all this will have an impact on the health system and public health in Sudan.”

Neighboring Chad is hosting a quarter million Sudanese refugees, and the U.N. expects an equal number will arrive in the country by the end of the year. “This will significantly increase the health needs and exert huge pressure on the available health facilities,” said Jean-Bosco Ndihokubwayo, WHO representative in Chad.

WHO reports around 2,500 people are arriving in Chad every day, many with serious gunshot wounds, while many others arrive sick with infectious diseases, malaria and cholera.

Ndihokubwayo cited malnutrition as the most serious health problem facing people in refugee camps.

“For the time being, we have more than 4,000 children who are suffering from serious malnutrition. Two hundred and fifty children are being hospitalized, 65 dead … and when this is combined with a disease like measles in children who are poorly nourished, it has huge effects as it does with our other current diseases,” he said.

The World Health Organization reports cases of malaria among children under age 5, as well as suspected cases of yellow fever also have been identified among some 17,000 Sudanese who have sought refuge in the Central African Republic (C.A.R.). It added that a suspected cholera outbreak has been reported among many displaced people in northern Ethiopia.

Magdalene Armah, Incident Manager for the Sudan Crisis, WHO regional office for Africa, said the African region has received 65% of the Sudanese population that has fled the country.

She said it was important to establish cross-border operations to ensure that all vulnerable populations are reached with health care. “We want to increase access to health care services by expanding the set-up of emergency teams that are in the various border regions.

“We want to ensure that vaccination campaigns can happen to mitigate further outbreaks. We want to ensure that disease surveillance goes down to the communities,” she said, adding that it was important that humanitarian agencies had the funding to enable it to carry out these vital health projects.

WHO and its partners are working to deliver emergency assistance and medical supplies to people in Chad, as well as in C.A.R., Egypt, Ethiopia and South Sudan, as swiftly as possible. But WHO says resources are overstretched, so providing aid to those in need is becoming increasingly difficult.

U.N. Secretary-General Antonio Guterres said Thursday that it is not too late to “stop the worst” of the climate crisis, but only with “dramatic, immediate” action.

“The era of global warming has ended; the era of global boiling has arrived,” Guterres told reporters at U.N. headquarters in New York, where the temperature outside was approaching 86 degrees Fahrenheit before 10 a.m. and set to hit 91 degrees Fahrenheit later in the day.

He spoke as the World Meteorological Organization and the European Commission’s Copernicus Climate Change Service released new data confirming July is set to be the hottest month ever recorded.

“According to the data released today, July has already seen the hottest three-week period ever recorded; the three hottest days on record; and the highest-ever ocean temperatures for this time of year,” Guterres said.

The U.N. chief, who has been ringing the alarm bell on the climate crisis since he entered office in January 2017, noted it has been a difficult summer in many parts of the world because of climate-related events, including fires, floods and scorching heat.

“For the entire planet, it is a disaster,” he said. “And for scientists, it is unequivocal – humans are to blame.”

He said the rising temperatures are consistent with all the scientific predictions; the only surprise is how fast it is happening.

He acknowledged progress on renewable energies and positive steps from industrial sectors but warned that none of it is going far or fast enough.

“Accelerating temperatures demand accelerated action,” the U.N. secretary-general said.

Guterres called for ambitious new national emissions reduction targets from G20 countries — as they are responsible for 80% of global greenhouse gas emissions. He urged developed countries to reach net zero emissions as close as possible to the target date of 2040, and emerging economies by 2050.

He also repeated his mantra that there must be a transition away from fossil fuels to renewables.

“And we must reach net zero electricity by 2035 in developed countries and 2040 elsewhere, as we work to bring affordable electricity to everyone on Earth,” the secretary-general noted.

He said countries on the climate “frontlines” — who have contributed the least to the climate crisis — need financial help from developed nations for adaptation and mitigation. Developed countries have committed to contributing $100 billion per year to help developing countries, but they have fallen short. Guterres urged them to honor those commitments.

In September, the U.N. chief will convene a Climate Ambition Summit on the sidelines of the General Assembly high-level week, ahead of November’s two-week long climate review conference — COP28 — in Dubai.

A system of ocean currents that transports heat northward across the North Atlantic could collapse by midcentury, according to a new study. Scientists have said that such a collapse could cause catastrophic sea level rise and extreme weather across the globe. 

In recent decades, researchers have both raised and downplayed the specter of Atlantic current collapse. It even prompted a movie that strayed far from the science. Two years ago, the U.N. Intergovernmental Panel on Climate Change said any such catastrophe was unlikely this century. But the new study published in Nature Communications suggests it might not be as far away and unlikely as mainstream science says. 

The Atlantic meridional overturning circulation is a vital system of ocean currents that circulates water throughout the Atlantic Ocean, according to the National Oceanic and Atmospheric Administration. It’s a lengthy process, taking an estimated 1,000 years to complete, but has slowed even more since the mid-1900s. 

A further slowdown or complete halting of the circulation could create more extreme weather in the Northern Hemisphere, sea level rise on the East Coast of the United States and drought for millions in southern Africa, scientists in Germany and the U.S. have said. But the timing is uncertain. 

In the new study, Peter and Susanne Ditlevsen, two researchers from Denmark, analyzed sea surface temperatures in the North Atlantic between 1870 and 2020 as a way of assessing this circulation. They found the system could collapse as soon as 2025 and as late as 2095, given current global greenhouse gas emissions.

“There are large uncertainties in this study, in many prior studies, and in climate impact assessment overall, and scientists sometimes miss important aspects that can lead to both over- and underprediction of impacts,” Julio Friedmann, chief scientist at Carbon Direct, a carbon management company, said in a statement. “Still, the conclusion is obvious: Action must be swift and profound to counter major climate risks.” 

Stefan Rahmstorf, co-author on a 2018 study on the subject, published an extensive analysis of the Ditlevesens’ study on RealClimate, a website that publishes commentary from climate scientists. While he said that a tipping point for the collapse of the Atlantic meridional overturning circulation was “highly uncertain,” he also called the IPCC estimate conservative. 

“Increasingly the evidence points to the risk being far greater than 10% during this century,” he wrote, “… rather worrying for the next few decades.”
