The provincial health department in the South African province of Gauteng on Sunday announced 19 new cases of Cholera in Hammanskraal, including 10 deaths. South Africa reported its first cholera death in February, after the virus arrived in the country from Malawi. It was unclear how many cholera cases there was nationally as of Sunday, but the most populous province of Gauteng, where Johannesburg and Pretoria are situated, has been hardest hit. Cholera can cause acute diarrhea, vomiting and weakness and is mainly spread by contaminated food or water. It can kill within hours if untreated. The last outbreak in South Africa was in 2008/2009 when about 12,000 cases were reported following an outbreak in neighboring Zimbabwe, which led to a surge of imported cases and subsequent local transmission. ...

Mexico's Popocatepetl volcano rumbled to life again this week, belching out towering clouds of ash that forced 11 villages to cancel school sessions. The residents weren't the only ones keeping a close eye on the towering peak. Every time there is a sigh, tic or heave in Popocatepetl, there are dozens of scientists, a network of sensors and cameras, and a roomful of powerful equipment watching its every move. The 5,426-meter volcano, known affectionately as "El Popo," has been spewing toxic fumes, ash and lumps of incandescent rock persistently for almost 30 years, since it awakened from a long slumber in 1994. The volcano is 72 kilometers southeast of Mexico City, but looms much closer to the eastern fringes of the metropolitan area of 22 million people. The city also…

The World Health Organization on Saturday launched a global network to help swiftly detect the threat from infectious diseases, like COVID-19, and share the information to prevent their spread. The International Pathogen Surveillance Network (IPSN) will provide a platform for connecting countries and regions, improving systems for collecting and analyzing samples, the agency said. The network aims to help ensure infectious disease threats are swiftly identified and tracked and the information shared and acted on to prevent catastrophes like the COVID pandemic. The network will rely on pathogen genomics to analyze the genetic code of viruses, bacteria and other disease-causing organisms to understand how infectious and deadly they are and how they spread. The data gathered will feed into a broader disease surveillance system used to identify and track diseases,…

The U.S. space agency NASA announced Friday it has awarded the Jeff Bezos-owned aerospace company Blue Origin a contract to build a second lunar lander for the Artemis V moon mission, aiming to land a crew on the moon by 2029. At a Washington news conference, NASA Administrator Bill Nelson said under the $3.4 billion contract, Blue Origin will design, develop, test and verify its Blue Moon lander to meet NASA's human landing system requirements for recurring astronaut expeditions to the lunar surface, including docking with Gateway, a space station where crews will transfer in lunar orbit.  Two years ago, Blue Origin made a bid on the contract NASA awarded to the Elon Musk-owned company SpaceX to build NASA's initial human landing system to be used in the agency's Artemis…

More than half of the world's large lakes and reservoirs have shrunk since the early 1990s, chiefly because of climate change, intensifying concerns about water for agriculture, hydropower and human consumption, a study published Thursday found. An international team of researchers reported that some of the world's most important water sources — from the Caspian Sea between Europe and Asia to South America's Lake Titicaca — lost water at a cumulative rate of about 22 gigatonnes per year for nearly three decades. That's about 17 times the volume of Lake Mead, the largest reservoir in the United States. Fangfang Yao, a surface hydrologist at the University of Virginia who led the study in the journal Science, said 56% of the decline in natural lakes was driven by climate warming and…

Mexican authorities said Thursday that they were trying to locate several hundred people, including U.S. nationals, potentially at risk of developing fungal meningitis after medical treatment near the border. The announcement came a day after the United States warned that suspected fungal infections had led to severe illness and even death among U.S. residents returning from the Mexican city of Matamoros. Around 400 people were being traced, including roughly 80 from the United States, according to the health minister of Tamaulipas state, home to Matamoros, which sits across the border from Brownsville, Texas. "They're going to be located to rule out that they are infected," Vicente Joel Hernandez told AFP. Two clinics, River Side Surgical Center and Clinica K-3, have been closed following the death of an American and the…

Shipwreck enthusiasts have cause for celebration because the Titanic ocean liner’s infamous wreck can now be visualized like never before. Deep-sea researchers have completed the first full-size digital scan of the Titanic, showing the entire wreck in clarity and detail. Researchers say it is the “largest underwater scanning project in history.” Unveiled on Wednesday, the 3D scan was the result of a six-week expedition to the North Atlantic wreck site in summer 2022, during which researchers used two remotely operated submersibles — named Romeo and Juliet — to map the entire shipwreck and the surrounding 3-mile debris field. The researchers took more than 700,000 images from every angle to create a virtual, exact 3D reconstruction. “It’s an absolutely one-to-one digital copy, a ‘twin,’ of the Titanic in every detail,” Anthony…

Drug overdose deaths in the U.S. went up slightly last year after two big leaps during the pandemic.  Officials with the Centers for Disease Control and Prevention say the numbers plateaued for most of last year. Experts aren't sure whether that means the deadliest drug overdose epidemic in U.S. history is finally reaching a peak, or whether it'll look like previous plateaus that were followed by new surges in deaths.  "The fact that it does seem to be flattening out, at least at a national level, is encouraging," said Katherine Keyes, a Columbia University epidemiology professor whose research focuses on drug use. "But these numbers are still extraordinarily high. We shouldn't suggest the crisis is in any way over."  An estimated 109,680 overdose deaths occurred last year, according to numbers…

"I remember my wife, Dora, coming home one day and telling me she had a problem while driving," said Bill Collier, a marketing professional living near Harrisburg, Pennsylvania. "She said she stopped at an intersection and suddenly couldn't remember where she was going."  That was in August of 2015. Then things got worse. Within months, Collier said Dora began experiencing nervous breakdowns and hallucinations on a nightly basis.  "She freaked out at me, at the world, at God — you name it," he told VOA. "Most nights we both ended up in tears because we didn't know what was going on or why it was happening."  It wasn't until nearly six years later, in February 2021, that Dora, now 57, was finally diagnosed with Alzheimer's disease, a progressive mental deterioration…

Countries can reduce plastic pollution by 80% by 2040 using existing technologies and by making major policy changes, the United Nations Environment Programme (UNEP) said in a new report on Monday. The Kenya-based U.N. body released its analysis of policy options to tackle the plastic waste crisis two weeks before countries convene in Paris for a second round of negotiations to craft a global treaty aimed at eliminating plastic waste. The report focuses on three main market shifts needed to create a "circular" economy that keeps produced items in circulation as long as possible: reuse, recycling and reorientation of packaging from plastic to alternative materials. "If we follow this road map, including in negotiations on the plastic pollution deal, we can deliver major economic, social and environmental wins,” said Inger…

Edna Adan Ismail, a nurse-midwife, hospital founder, and health care advocate who for decades has combated female genital mutilation and strived to improve women's health care in East Africa, was named Tuesday as winner of the 2023 Templeton Prize, one of the world's largest annual individual awards. "Rooted in her Muslim faith, she receives this year's award in recognition of her extraordinary efforts to harness the power of the sciences to affirm the dignity of women and help them to flourish physically and spiritually," said the announcement. Among her achievements: the founding of a hospital and university which have significantly reduced maternal mortality in Somaliland. The Templeton Prize, valued at nearly $1.4 million, was established in 1973 by philanthropist Sir John Templeton. It honors those "who harness the power of…

English soccer star Jimmy Fryatt was known for his ability to head the ball, and the proof of his prowess may be in the damage it did to his brain. Still physically fit in his late 70s, Fryatt played tennis but couldn't keep score or remember which side of the net he was supposed to be on. He lived in Las Vegas for almost 50 years but started to get lost while riding his bicycle in the neighborhood. "I had to put a tracker on him," his wife, Valerie, said this week. "I'd call him and say: 'Stop. I'm coming to get you.'" A North American Soccer League champion who played 18 years in Britain, Fryatt is one of four former professional soccer players newly diagnosed with chronic traumatic encephalopathy.…

Climate change does not make cyclones, such as the one battering Bangladesh, more frequent, but it does render them more intense and destructive, according to climatologists and weather experts. These immensely powerful natural phenomena have different labels according to the region they hit, but cyclones, hurricanes and typhoons are all violent tropical storms that can generate 10 times as much energy as the Hiroshima atomic bomb. They are divided into different categories according to their maximum sustained wind strength and the scale of damage they can potentially inflict. Cyclones, hurricanes and typhoons "A cyclone is a low-pressure system that forms in the tropics in an area hot enough for it to develop," Emmanuel Cloppet, from French weather office Meteo France, told AFP. "It is characterized by rain/storm clouds that start…

Pacific Island leaders criticized rich countries Monday for not doing enough to control climate change despite being responsible for much of the problem, and for making money off loans provided to vulnerable nations to mitigate the effects. Leaders and representatives from Pacific Island nations demanded at a U.N. climate change conference in Bangkok that the world make more effort to put aside differences in combating the environmental impact, especially as their countries emerge from the economic devastation of the COVID-19 pandemic. Prime Minister Mark Brown of the Cook Islands said the finance model for combatting climate change — giving out loans to reduce the impact — is “not the way to go” for countries in his region with such small populations that produce “inconsequential amounts of carbon emissions” but suffer…

In South Africa, women make up only 13% of graduates with degrees in the fields of Science, Technology, Engineering, and Mathematics. In an effort to interest more young women in those fields, a retired US astronaut is visiting schools in South Africa. Zaheer Cassim reports from Johannesburg. ...

In the southern Chilean city of Santa Juana, hit hard by wildfires earlier this year, locals have a special taskforce helping fight blazes: a herd of goats. The goats have already saved the native forest of the Bosques de Chacay once in February, preventing the park from being consumed by forest fires - fueled by heatwaves and a punishing drought - that left dozens dead, thousands injured and almost 440,000 hectares destroyed in south-central Chile. "The park was surrounded by fires, but it ended up being the only green spot left," said Rocio Cruces, cofounder of the 16-hectare (40-acre) park, and "Buena Cabra," a project that uses goats to build firebreaks. The technique, also used in Portugal and Spain, relies on grazing goats to control dry pastures and other vegetation…
