Geneva — A senior World Health Organization official expressed alarm Tuesday at the high risk of polio spreading within the Gaza Strip because of dire sanitary conditions in the war-wracked enclave, and that the paralytic disease it causes could spill across borders without prompt action to stem the outbreak. “I am, like, super worried,” Dr. Avadil Saparbekov, team lead for health emergencies at the WHO in the occupied Palestinian territory, told journalists from Jerusalem. “I am extremely worried about an outbreak happening in Gaza … and that it may spill over internationally at a very high point.”  Saparbekov, who recently returned from a weeklong visit to Gaza, confirmed that “circulating vaccine-derived poliovirus type 2” has been identified in samples of Gazan sewage assessed by researchers and that an epidemiological probe “to identify the potential source of this importation” is underway. “Based on the results of the assessment, WHO and the GPEI …

United Nations — Nearly 40 million people were living with the HIV virus that causes AIDS last year, over 9 million weren’t getting any treatment, and the result was that every minute someone died of AIDS-related causes, the U.N. said in a new report launched Monday. While advances are being made to end the global AIDS pandemic, the report said progress has slowed, funding is shrinking, and new infections are rising in three regions: the Middle East and North Africa, Eastern Europe and Central Asia, and Latin America. In 2023, around 630,000 people died from AIDS-related illnesses, a significant decline from the 2.1 million deaths in 2004. But the latest figure is more than double the target for 2025 of fewer than 250,000 deaths, according to the report by UNAIDS, the U.N. agency leading the global effort to end the pandemic. Gender inequality is exacerbating the risks for girls and women, …

BENGALURU, India — At a Coca-Cola factory on the outskirts of Chennai in southern India, a giant battery powers machinery day and night, replacing a diesel-spewing generator. It’s one of just a handful of sites in India powered by electricity stored in batteries, a key component to fast-tracking India’s energy transition away from dirty fuels.    The country’s lithium ion battery storage industry — which can store electricity generated by wind turbines or solar panels for when the sun isn’t shining or the wind isn’t blowing — makes up just 0.1% of global battery storage systems. But battery storage is growing fast, with around a third of India’s total battery infrastructure coming online just this year.    “Our orders are growing exponentially,” said Ayush Misra, CEO of Amperehour Energy, the company that installed the batteries at the Chennai factory. “It’s a really exciting time to be a battery storage provider.”    Businesses invest in …

new york — As U.S. health officials investigate a fatal outbreak of listeria food poisoning, they’re advising people who are pregnant, elderly or have compromised immune systems to avoid eating sliced deli meat unless it’s recooked at home to be steaming hot. The U.S. Centers for Disease Control and Prevention didn’t mandate a food recall as of early Saturday, because it remains unclear what specific products have been contaminated with the bacteria now blamed for two deaths and 28 hospitalizations across 12 states. This means the contaminated food may still be in circulation, and consumers should consider their personal risk level when consuming deli meats. Federal health officials warned Friday that the number of illnesses is likely an undercount, because people who recover at home aren’t likely to be tested. For the same reason, the outbreak may have spread wider than the states where listeria infections have been reported, mostly in …

Washington — Russia and China are edging ever closer to unleashing space-based weapons, a decision that could have far-reaching implications for America’s ability to defend itself, U.S. military and intelligence agencies warn. Adding to the concern, they say, is what appears to be a growing willingness by both countries to set aside long-running suspicions and animosity in order to gain an edge over the United States. “I would highlight … the increasing amount in intent to use counterspace capabilities,” said Lieutenant General Jeff Kruse, director of the Defense Intelligence Agency. “Both Russia and China view the use of space early on, even ahead of conflict, as important capabilities to deter or to compel behaviors,” Kruse told the annual Aspen Security Forum on Wednesday. “We just need to be ready.” Concerns about the safety of space surged earlier this year when House Intelligence Committee Chairman Mike Turner called for the declassification of …

Blantyre, Malawi     — Malawi has declared the end of the country’s worst cholera outbreak, which began in March 2022 and killed nearly 2,000 people. In a statement Monday, the Ministry of Health said the country had registered no cases or deaths from cholera in 26 of Malawi’s 29 health districts in the past four weeks. Some health experts, however, said the outbreak could resurface if the country failed to address sanitation problems that caused it. Malawi President Lazarus Chakwera launched a national campaign to end the cholera outbreak in February 2023. The “Tithetse Kolera” or “Let’s End Cholera” campaign came three months after he declared the disease to be a public health emergency in Malawi. The campaign aimed to interrupt cholera transmission in all districts and reduce the fatality rate from 3.2% to below 1%, which the World Health Organization considers a controlled cholera outbreak. Dr. Wilfred Chalamira Nkhoma,  co-chairperson …

LONDON — The world’s second vaccine against malaria was launched on Monday as Ivory Coast began a routine vaccine program using shots developed by the University of Oxford and the Serum Institute of India.  The introduction of the World Health Organization (WHO)-approved R21 vaccine comes six months after the first malaria vaccine, called RTS,S and developed by British drugmaker GSK, began being administered in a routine program in Cameroon.  Some 15 African countries plan to introduce one of the two malaria vaccines this year with support from the Gavi global vaccine alliance.  Ivory Coast has received a total of 656,600 doses of the Oxford and Serum shot, which will initially vaccinate 250,000 children aged between 0 and 23 months across the West African country. The vaccine has also been approved by Ghana, Nigeria, Burkina Faso and the Central African Republic.  The rollout of a second vaccine is the latest milestone in …

CAPE CANAVERAL, Fla. — Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago, and suspect there are hundreds more that could house future astronauts. An Italian-led team reported Monday that there’s evidence for a sizable cave accessible from the deepest known pit on the moon. It’s located at the Sea of Tranquility, just 250 miles (400 kilometers) from Apollo 11’s landing site. The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube. Researchers analyzed radar measurements by NASA’s Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth. Their findings appeared in the journal Nature Astronomy.  …
