TEFE, Brazil — The carcass of a baby dolphin lay on the sand bank left exposed by the receding waters in an Amazon lake that has been drying up during the worst drought on record.  Researchers recovered the dead animal on Wednesday and measured water temperatures that have been rising as the lake’s level drops. In last year’s drought, more than 200 of the endangered freshwater dolphins died in Lake Tefe from excessive water temperatures.  “We’ve found several dead animals. Last week, we found one a day on average,” said Miriam Marmontel, head of the dolphin project at the Mamiraua Institute for Sustainable Development.   “We’re not yet associating the deaths with changes in water temperatures, but with the exacerbation of the proximity between human populations, mainly fishermen, and the animals,” she said.  With branches of major rivers in the Amazon basin drying up in this year’s critical drought, the lake …

LOUISVILLE, Kentucky — On his first day of school at Newcomer Academy, Maikel Tejeda was whisked to the school library. The 7th grader didn’t know why. He soon got the point: He was being given make-up vaccinations. Five of them. “I don’t have a problem with that,” said the 12-year-old, who moved from Cuba early this year. Across the library, a group of city, state and federal officials gathered to celebrate the school clinic, and the city. With U.S. childhood vaccination rates below their goals, Louisville and the state were being praised as success stories: Kentucky’s vaccination rate for kindergarteners rose 2 percentage points in the 2022-23 school year compared with the year before. The rate for Jefferson County — which is Louisville — was up 4 percentage points. “Progress is success,” said Dr. Mandy Cohen, director of the Centers for Disease Control and Prevention. But that progress didn’t last. Kentucky’s …

PORTLAND, Maine — Fall is back, and bringing with it jack-o’-lanterns, football, pumpkin spice everything and — in some parts of the country — especially vibrant foliage. Leaves around the northern United States are starting to turn orange, yellow and red, inspiring legions of leaf lovers to hop in their cars and travel to the countryside for the best look at fall’s fireworks. Leaf peeping — the act of traveling to witness nature’s annual kaleidoscope — contributes billions of dollars to the economy, especially in New England and New York. But this year, some of the most colorful displays could be in the Midwest. AccuWeather, the commercial forecasting service, said in early September that it expects especially vibrant foliage in states such as Michigan and Illinois. The service also said powerful, popping colors are expected in upstate New York and parts of Pennsylvania, while New England will follow a more typical …

NEW YORK — Six years after a teenage Greta Thunberg walked out of school in a solitary climate protest outside of the Swedish parliament, people around a warming globe marched in youth-led protest, saying their voices are being heard but not sufficiently acted upon. Emissions of heat-trapping gases and temperatures have been rising and oil and gas drilling has continued, even as the protests that kicked off major weeklong climate events in New York City have become annual events. This year, they come days before the United Nations convenes two special summits, one concentrating on sea level rise and the other on the future. The young people who organized these marches with Fridays for Future said there is frustration with inaction but also hope. People marched in Berlin, Rio de Janeiro, New Delhi and elsewhere, but the focus often is in New York City because of Climate Week NYC. Diplomats, business …

KAVUMU, Congo — Health authorities have struggled to contain outbreaks of mpox in Congo, a huge central African country where a myriad of existing problems makes stemming the spread particularly hard. Last month, the World Health Organization declared the outbreaks in Congo and about a dozen other African countries a global health emergency. And in Congo, scientists have identified a new strain of mpox that may spread more easily. It has reached areas where conflict and the displacement of a large number of people have already put health services under pressure. Overall, Congo has more than 21,000 of the 25,093 confirmed and suspected mpox cases in Africa this year, according to WHO’s most recent count. Has Congo seen cases of mpox before? Yes, Congo is one of the African countries where mpox has been endemic for decades. Mpox, once known as monkeypox, comes from the same family of viruses as smallpox …

Harare, Zimbabwe — A new report released by the main United Nations agency for action on AIDS and HIV says growing public debt is choking sub-Saharan African countries, leaving them with little fiscal room to finance critical HIV services. In the report, launched ahead of the 79th session of the U.N. General Assembly in New York, Winnie Byanyima, the executive director of UNAIDS, asks the international community for more funding to ensure Africa eliminates AIDS by 2030. She said Africa, which accounts for the largest number of people living with HIV — some 26 million out of 40 million globally — is overwhelmed by public debt. Robert Shivambu, UNAIDS communication officer, told VOA: “The region’s success in having reduced new HIV infections by 56% since 2010 will not be sustained if fiscal space is constrained.” Shivambu said the U.N. believes that when debt payments hinder countries’ ability to effectively look after …

GENEVA — The United Nations Children’s Fund, or UNICEF, warned Friday that children in Burundi are bearing the brunt of the mpox outbreak, with cases of this deadly, infectious disease spreading at an alarming rate among a young population. “Of the nearly 600 reported cases, two-thirds are in children under 19. The situation has escalated rapidly, with a more-than-40% increase in cases over the past three weeks,” Dr. Paul Ngwakum, UNICEF’s regional health adviser for Eastern and Southern Africa, told journalists in Geneva via video link Friday. Ngwakum, who currently is on a visit to Burundi, said, “The fear expressed by the parents and the resilience of communities in the face of this public health crisis” and the rapid escalation of the disease “were striking.” Speaking from the capital, Bujumbura, he said the rise of mpox among children under the age of 5 is of particular concern as they represent 30% of the reported cases. …

LONDON — Scientists searching for the origins of COVID-19 have zeroed in on a short list of animals that possibly helped spread it to people, an effort they hope could allow them to trace the outbreak back to its source. Researchers analyzed genetic material gathered from the Chinese market where the first outbreak was detected and found that the most likely animals were raccoon dogs, civet cats and bamboo rats. The scientists suspect infected animals were first brought to the Wuhan market in late November 2019, which then triggered the pandemic. Michael Worobey, one of the new study’s authors, said they found which sub-populations of animals might have transmitted the coronavirus to humans. That may help researchers pinpoint where the virus commonly circulates in animals, known as its natural reservoir. “For example, with the raccoon dogs, we can show that the raccoon dogs that were [at the market] … were from …

People from across the globe are convening on the sidelines of the U.N. General Assembly in New York City for Climate Week. On the agenda: the environmental impact of seabed mining. The discussion comes as tech companies seek ways to fuel the green revolution while minimizing environmental impacts. VOA’s Jessica Stone has more.] …

CHONBURI, Thailand — Only a month after Thailand’s adorable baby hippo Moo Deng was unveiled on Facebook, her fame became unstoppable both domestically and internationally. Zookeeper Atthapon Nundee has been posting cute moments of the animals in his care for about five years. He never imagined Khao Kheow Open Zoo’s newborn pygmy hippo would become an internet megastar within weeks. Cars started lining up outside the zoo well before it opened Thursday. Visitors traveled from near and far for a chance to see the pudgy, expressive 2-month-old in person at the zoo about 100 kilometers southeast of Bangkok. The pit where Moo Deng lives with her mom, Jona, was packed almost immediately, with people cooing and cheering every time the pink-cheeked baby animal made skittish movements. “It was beyond expectation,” Atthapon told The Associated Press. “I wanted people to know her. I wanted a lot of people to visit her, or …

Addis Ababa, Ethiopia — One of the hurdles to improving health care systems for African countries is the shortage of scientists and lack of meaningful medical research on the continent, experts say. An organization hopes to change that by enabling researchers and policymakers in three large African countries to develop more extensive and relevant research. According to a 2017 report by the World Economic Forum, Africa is home to 15% of the world’s population and 25% of the world’s disease burden — but produces just 2% of the world’s medical research. The report said of the medical research that does occur, much of it fails to prioritize diseases or health problems most pressing for Africans. A group of African health researchers and institutions are now pushing for the continent’s medical research to be more focused on the continent’s own medical problems. The African Population and Health Research Center is bringing together …

Washington — When activists, policymakers and representatives from across the globe gather next week in New York to participate in climate week, one pressing issue on the agenda that is less frequently discussed and known will be the environmental impact of seabed mining. As countries look for ways to lower emissions, critical minerals are playing a key role in that transition. Critical minerals are used in all kinds of green technologies, from solar panels and wind turbines to batteries in electric vehicles. And one place where those mineral resources are abundant is deep under the sea. The debate over accessing seabed resources is heated. Supporters say the technology exists to safely access these critical minerals undersea, but environmentalists and activists say the potential of undiscovered biodiversity on the seafloor is too important to endanger. During climate week, which will take place on the sidelines of U.N. General Assembly meetings, organizers are …
