Scientists: Climate change, rapid urbanization worsen impact of East African rains

All, News
NAIROBI, Kenya — The impact of the calamitous rains that struck East Africa from March to May was intensified by a mix of climate change and rapid growth of urban areas, an international team of climate scientists said in a study published Friday. The findings come from World Weather Attribution, a group of scientists that analyzes whether and to what extent human-induced climate change has altered the likelihood and magnitude of extreme weather events. The downpours caused floods that killed hundreds of people, displaced thousands of others, killed thousands of livestock and destroyed thousands of acres of crops. To assess how human-caused climate may have affected the floods, the researchers analyzed weather data and climate model simulations to compare how these types of events have changed between today's climate and the…

World’s largest tree passes health check

All, News
SEQUOIA NATIONAL PARK, California — High in the evergreen canopy of General Sherman, the world's largest tree, researchers searched for evidence of an emerging threat to giant sequoias: bark beetles. The climbers descended the towering 2,200-year-old tree with good news on Tuesday. "The General Sherman tree is doing fine right now," said Anthony Ambrose, executive director of the Ancient Forest Society, who led the expedition. "It seems to be a very healthy tree that's able to fend off any beetle attack." It was the first time climbers had scaled the iconic 85-meter sequoia tree, which draws tourists from around the world to Sequoia National Park. Giant sequoias, the Earth's largest living things, have survived for thousands of years in California's western Sierra Nevada range, the only place where the species is…

IS turns to artificial intelligence for advanced propaganda amid territorial defeats

All, Business, News, Technology
Washington — With major military setbacks in recent years, supporters of the Islamic State terror group are increasingly relying on artificial intelligence (AI) to generate online propaganda, experts said. A new form of propaganda developed by IS supporters is broadcasting news bulletins with AI-generated anchors in multiple languages. The Islamic State Khorasan (ISKP) group, an IS affiliate active in Afghanistan and Pakistan, produced in a video an AI-generated anchorman to appear reading news following an IS-claimed attack in Bamiyan province in Afghanistan on May 17 that killed four people, including three Spanish tourists. The digital image posing as an anchor spoke the Pashto language and had features resembling local residents in Bamiyan, according to The Khorasan Diary, a website dedicated to news and analysis on the region. Another AI-generated propaganda video…

Ocean heat, La Nina likely mean more Atlantic hurricanes this summer

All, News
WASHINGTON — Get ready for what nearly all the experts think will be one of the busiest Atlantic hurricane seasons on record, thanks to unprecedented ocean heat and a brewing La Nina.  There's an 85% chance that the Atlantic hurricane season starting in June will be above average in storm activity, the National Oceanic and Atmospheric Administration announced Thursday in its annual outlook. The weather agency predicted between 17 and 25 named storms will brew up this summer and fall, with eight to 13 achieving hurricane status (at least 75 mph sustained winds) and four to seven of them becoming major hurricanes, with at least 111 mph winds.  An average Atlantic hurricane season produces 14 named storms — seven of them hurricanes and three major hurricanes.  "This season is looking to…

Michigan farmworker diagnosed with bird flu in 2nd US case tied to dairy cows

All, News
New York — A Michigan dairy worker has been diagnosed with bird flu — the second human case associated with an outbreak in U.S. dairy cows.  The patient had mild eye symptoms and has recovered, U.S. and Michigan health officials said in announcing the case Wednesday. The worker had been in contact with cows presumed to be infected, and the risk to the public remains low, officials said.  A nasal swab from the person tested negative for the virus, but an eye swab tested positive, "indicating an eye infection," the U.S. Centers for Disease Control and Prevention said in a statement.  The first case happened in late March, when a farmworker in Texas was diagnosed in what officials called the first known instance globally of a person catching this version of…

Australian researchers unveil device that harvests water from the air

All, Business, News, Technology
SYDNEY — A device that absorbs water from air to produce drinkable water was officially launched in Australia Wednesday. Researchers say the so-called Hydro Harvester, capable of producing up to 1,000 liters of drinkable water a day, could be “lifesaving during drought or emergencies.” The device absorbs water from the atmosphere. Solar energy or heat that is harnessed from, for example, industrial processes are used to generate hot, humid air. That is then allowed to cool, producing water for drinking or irrigation. The Australian team said that unlike other commercially available atmospheric water generators, their invention works by heating air instead of cooling it. Laureate Professor Behdad Moghtaderi, a chemical engineer and director of the University of Newcastle’s Centre for Innovative Energy Technologies, told VOA how the technology operates.   “Hydro Harvester…

Small island states secure climate win at international ocean court

All, News
BERLIN — A group of small island states that include Antigua and Barbuda and the Bahamas secured a win on climate change in an international court Tuesday as they seek to combat rising sea levels. In its first climate-related judgment, the International Tribunal for the Law of the Sea, or ITLOS, said that greenhouse gas emissions absorbed by the ocean are considered marine pollution and countries are obliged to protect marine environments by going further than required under the Paris climate agreement. The opinion was requested by a group of nine island nations facing climate-driven rises in sea levels. The opinion is not legally binding, but it can be used to help guide countries in their climate policy and, in other cases, as legal precedent. "The ITLOS opinion will inform our…

Global carbon emissions pricing raised record $104 bln in 2023

All, News
LONDON — Countries raised a record $104 billion last year by charging firms for emitting carbon dioxide, but prices remain too low to drive changes needed to meet Paris climate accord targets, the World Bank said in a report on Tuesday.   Several countries are using a price on carbon emissions to help meet their climate goals by making polluters pay in the form of a tax, or under an emissions trading (ETS), or cap-and-trade, system. “Carbon pricing is a critical part of the policy mix needed to both meet the Paris Agreement goals and support low emissions growth,” the World Bank’s State and Trends of Carbon Markets report said.   There are 75 global carbon pricing instruments in operation, up two from a year ago, covering around 24% of global…

Study: Climate change key driver of record-low Antarctic sea ice

All, News
Paris — Climate change played a key role in last year's record-low levels of Antarctic sea ice, a study published on Monday found, marking an abrupt shift from the growth seen in previous decades. Scientists from the British Antarctic Survey (BAS) found that human-caused global warming resulted in a once-in-2,000-year low in ocean surface around the continent blanketed by ice. Compared to an average winter over the last several decades, the maximum extent of Antarctic sea covered by ice shrank by two million square kilometers — an area four times the size of France, the BAS said. "This is why we were so interested in studying what climate models can tell us about how often large, rapid losses like this are likely to happen," the study's lead author Rachel Diamond told…

Researchers use artificial intelligence to classify brain tumors

All, Business, News, Technology
SYDNEY — Researchers in Australia and the United States say that a new artificial intelligence tool has allowed them to classify brain tumors more quickly and accurately.   The current method for identifying different kinds of brain tumors, while accurate, can take several weeks to produce results.  The method, called DNA methylation-based profiling, is not available at many hospitals around the world. To address these challenges, a research team from the Australian National University, in collaboration with the National Cancer Institute in the United States, has developed a way to predict DNA methylation, which acts like a switch to control gene activity.   This allows them to classify brain tumors into 10 major categories using a deep learning model. This is a branch of artificial intelligence that teaches computers to process…

Companies trying to attract more smartphone users across Africa, but there are risks

All, Business, News, Technology
Accra, Ghana — Anita Akpeere prepared fried rice in her kitchen in Ghana's capital as a flurry of notifications for restaurant orders lit up apps on her phone. "I don't think I could work without a phone in my line of business," she said, as requests came in for her signature dish, a traditional fermented dumpling. Internet-enabled phones have transformed many lives, but they can play a unique role in sub-Saharan Africa, where infrastructure and public services are among the world's least developed, said Jenny Aker, a professor who studies the issue at Tufts University. At times, technology in Africa has leapfrogged gaps, including providing access to mobile money for people without bank accounts. Despite growing mobile internet coverage on the continent of 1.3 billion people, just 25% of adults in…

What happened in the UK’s infected blood scandal? Inquiry report due Monday

All, News
London — The final report of the U.K.'s infected blood inquiry will be published Monday, nearly six years after it began looking into how tens of thousands of people contracted HIV or hepatitis from transfusions of tainted blood and blood products in the 1970s and 1980s. The scandal is widely seen as the deadliest to afflict Britain's state-run National Health Service since its inception in 1948, with around 3,000 people believed to have died as a result of being infected with HIV and hepatitis, an inflammation of the liver. The report is expected to criticize pharmaceutical firms and medical practitioners, civil servants and politicians, although many have already died given the passage of time. It's also set to pave the way to a huge compensation bill that the British government will…

Illness took away her voice. AI created a replica she carries in her phone

All, Business, News, Technology
PROVIDENCE, RHODE ISLAND — The voice Alexis "Lexi" Bogan had before last summer was exuberant. She loved to belt out Taylor Swift and Zach Bryan ballads in the car. She laughed all the time — even while corralling misbehaving preschoolers or debating politics with friends over a backyard fire pit. In high school, she was a soprano in the chorus. Then that voice was gone. Doctors in August removed a life-threatening tumor lodged near the back of her brain. When the breathing tube came out a month later, Bogan had trouble swallowing and strained to say "Hi" to her parents. Months of rehabilitation aided her recovery, but her speech is still impaired. Friends, strangers and her own family members struggle to understand what she is trying to tell them. In April,…

Patient with sickle cell disease offers hope to Ugandan community

All, News
mbale, uganda — Barbara Nabulo was one of three girls in her family. But when a sister died, her mother wailed at the funeral that she was left with just one and a half daughters. The half was the ailing Nabulo, who at age 12 understood her mother's meaning. "I hated myself so much," Nabulo said recently, recalling the words that preceded a period of sickness that left her hospitalized and feeding through a tube. The scene underscores the lifelong challenges for some people with sickle cell disease in rural Uganda, where it remains poorly understood. Despite Nabulo's knowledge of how the disease weakens the body, she spoke repeatedly of "the germ I was born with." Infections, pain, organ damage Sickle cell disease is a group of inherited disorders in which…
