GENEVA — U.N. agencies warn that the demolition of a critical water facility in Rafah in the southern Gaza Strip increases the risk of infectious diseases as people are forced to drink unsafe water while sanitary conditions continue to deteriorate. “Until recently, that reservoir served thousands and thousands of internally displaced people who had sought refuge in Rafah in the area,” James Elder, UNICEF spokesperson, told journalists at a briefing in Geneva on Tuesday. “Now without it, vulnerable children and families are likely to be forced again increasingly to resort to unsafe water, so putting them again at all those risks that we see time after time, day after day in Gaza — dehydration, malnutrition, diseases,” he said. The Israeli daily Haaretz reported Monday that the troops blew up the central reservoir “on the orders of the brigade commanders” but without receiving permission from the senior level of the Southern Command. …

Bangkok — Millions of lives could be put at risk unless urgent action is taken to curb the spread of drug-resistant malaria in Africa, according to a new paper published in the journal Science. The paper says the parasite that causes malaria is showing signs of resistance to artemisinin, the main drug used to fight the disease, in several east African countries. “Mutations indicating artemisinin-resistance have been found in more than 10% of malaria infected individuals in Ethiopia, Eritrea, Rwanda, Uganda, and Tanzania,” according to the report. Artemisinin Combination Therapies, or ACTs, have been the cornerstone of malaria treatment in recent years — but there are worrying signs that they are becoming less effective, says report co-author Lorenz von Seidlein of the Mahidol Oxford Tropical Medicine Research Unit in Bangkok. “We have increasing reports from eastern Africa saying that they have documented resistance against the first line treatments against malaria,” he says. …

GALAPAGOS ISLANDS, Ecuador — Warm morning light reflects from the remains of a natural rock arch near Darwin Island, one of the most remote islands in the Galapagos. In clear, deep blue water, thousands of creatures — fish, hammerhead sharks, marine iguanas — move in search of food. The 2021 collapse of Darwin’s Arch, named for the famed British naturalist behind the theory of evolution, came from natural erosion. But its demise underscored the fragility of a far-flung archipelago that’s coming under increased pressure both from climate change and invasive species. Warming oceans affect the food sources of many of the seagoing animals in the Galapagos. Marine iguanas — one of many species that are endemic, or unique, to the Galapagos — have a harder time finding the red and green algae they prefer. Sea turtles struggle to nest in warmer temperatures. Raising young gets harder as water warms and fewer …

Washington — New blood tests could help doctors diagnose Alzheimer’s disease faster and more accurately, researchers reported Sunday – but some appear to work far better than others. It’s tricky to tell if memory problems are caused by Alzheimer’s. That requires confirming one of the disease’s hallmark signs — buildup of a sticky protein called beta-amyloid — with a hard-to-get brain scan or uncomfortable spinal tap. Many patients instead are diagnosed based on symptoms and cognitive exams. Labs have begun offering a variety of tests that can detect certain signs of Alzheimer’s in blood. Scientists are excited by their potential, but the tests aren’t widely used yet because there’s little data to guide doctors about which kind to order and when. The U.S. Food and Drug Administration hasn’t formally approved any of them and there’s little insurance coverage. “What tests can we trust?” asked Dr. Suzanne Schindler, a neurologist at Washington …

KENITRA, Morocco — Golden fields of wheat no longer produce the bounty they once did in Morocco. A six-year drought has imperiled the country’s entire agriculture sector, including farmers who grow cereals and grains used to feed humans and livestock. The North African nation projects this year’s harvest will be smaller than last year in both volume and acreage, putting farmers out of work and requiring more imports and government subsidies to prevent the price of staples like flour from rising for everyday consumers. “In the past, we used to have a bounty — a lot of wheat. But during the last seven or eight years, the harvest has been very low because of the drought,” said Al Housni Belhoussni, a small-scale farmer who has long tilled fields outside of the city of Kenitra. Belhoussni’s plight is familiar to grain farmers throughout the world confronting a hotter and drier future. Climate …

sydney, australia — The world’s largest platypus conservation center has welcomed its first residents as part of a project to protect the semi-aquatic mammal found only in Australia amid threats to its habitat from extreme weather and humans.  The four platypuses — two females and two males — were released over the last two weeks into a custom-built research facility at Taronga Western Plains Zoo in Dubbo, about 400 kilometers (250 miles), northwest of Sydney.   Featuring multi-tiered streams, waterfalls, pools and earth banks for burrowing, the facility will help researchers understand more about the species, Taronga Conservation Society Australia official Phoebe Meagher told Reuters.  “This facility will allow us to not only save the species from the immediate threats of climate change, but also in the long term, be able to repopulate those populations,” she said.  “We would love to see some puggles or baby platypus in the facility and …

HONOLULU — A Hawaii judge has temporarily blocked the state from enforcing a law requiring the licensing of practitioners and teachers of traditional Native Hawaiian midwifery while a lawsuit seeking to overturn the statute wends its way through the courts. Lawmakers enacted the midwife licensure law, which asserted that the “improper practice of midwifery poses a significant risk of harm to the mother or newborn, and may result in death,” in 2019. Violations are punishable by up to a year in jail, plus thousands of dollars in criminal and civil fines. The measure requires anyone who provides “assessment, monitoring, and care” during pregnancy, labor, childbirth and the postpartum period to be licensed. A group of women sued, arguing that a wide range of people, including midwives, doulas, lactation consultants and even family and friends of the new mother would be subject to penalties and criminal liability. Their complaint also said the …

washington — NASA’s rover Perseverance on Mars has made what could be its most astonishing discovery to date: possible signs of ancient life on the Red Planet. The six-wheeled robotic explorer came across an intriguing, arrow-shaped rock dubbed “Cheyava Falls” that may harbor fossilized microbes from billions of years ago, when Mars was a watery world. Perseverance drilled into the enigmatic rock to collect a core sample on July 21, as it traversed Neretva Vallis, an ancient river valley. The samples carefully stowed beneath the rover’s belly are destined to eventually return to Earth, where they will undergo more comprehensive analysis. “Cheyava Falls is the most puzzling, complex, and potentially important rock yet investigated by Perseverance,” project scientist Ken Farley of Caltech said Thursday. Three compelling clues have scientists buzzing. White calcium sulfate veins run the length of the rock, a telltale sign that water once flowed through it. Between these …

washington — Thousands of policymakers, health care professionals and advocates gathered this week in Munich, Germany, to take stock of the global fight against HIV as they try to meet the 2030 deadline set by world leaders for eliminating AIDS as a public health threat. Advocates hailed sub-Saharan Africa’s progress in the global HIV response, with tens of millions of people now on lifesaving drugs. A new UNAIDS survey released during the conference reported that “approximately 30.7 million of the estimated 39.9 million people living with HIV globally were receiving antiretroviral therapy in 2023.” The report called that result a “landmark public health achievement,” and health officials at the conference said it would not be possible without the “immense political will” of regional leaders and NGOs. Anne Githuku-Shongwe, the UNAIDS regional director for eastern and southern Africa, told VOA from Johannesburg that recently there has been a “huge focus” on ensuring …

United Nations — The U.N. Secretary-General warned Thursday that the Earth is becoming hotter and more dangerous for everyone, killing nearly a half-million people annually, and he blamed fossil fuels for driving global warming. “Billions of people are facing an extreme heat epidemic — wilting under increasingly deadly heat waves, with temperatures topping 50 degrees Celsius around the world. That’s 122 degrees Fahrenheit. And halfway to boiling,” Antonio Guterres told reporters. Sunday was the Earth’s hottest day on record, only to have the record broken the following day. Temperatures have been rising steadily, with scientists declaring the last 13 consecutive months all heat record-breakers. Urban areas are heating up at twice the global average. Heat waves have killed scores of people this year in India and in Africa’s Sahel region. Last month, extreme heat killed 1,300 Muslim pilgrims in Saudi Arabia. This month, Europe, the United States and Asia have also …

CAPE CANAVERAL, Florida — A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit.  The planet is roughly the same diameter as Jupiter, but with six times the mass. Its atmosphere is also rich in hydrogen like Jupiter’s.  One big difference: It takes this planet more than a century, possibly as long as 250 years, to go around its star. It’s 15 times the distance from its star than Earth is to the sun.  Scientists had long suspected a big planet circled this star 12 light-years away, but not this massive or far from its star. A light-year is 5.8 trillion miles. These new observations show the planet orbits the star Epsilon Indi A, part of a three-star system.  An international team led by Max Planck Institute for Astronomy’s Elisabeth Matthews in Germany collected the images last year and …
