Oversight Board Urges Meta to Rethink Policy on Manipulated Media

All, Business, News, Technology
NEW YORK — An oversight board is criticizing Facebook owner Meta's policies regarding manipulated media as "incoherent" and insufficient to address the flood of online disinformation that already has begun to target elections across the globe this year.  The quasi-independent board on Monday said its review of an altered video of President Joe Biden that spread on Facebook exposed gaps in the policy. The board said Meta should expand the policy to focus not only on videos generated with artificial intelligence, but on media regardless of how it was created. That includes fake audio recordings, which already have convincingly impersonated political candidates in the U.S. and elsewhere.  It also said Meta should clarify the harm it is trying to prevent and should label images, videos and audio clips as manipulated instead…

Study Finds Ocean Heatwaves Could Affect Global Food Supplies

All, News
SYDNEY — A new study finds that marine heatwaves are changing the base of the marine food chain, disrupting ecosystems and potentially global food supplies. Researchers in the investigation led by Australia’s national science agency, CSIRO, say their work has global implications. The study monitored the health of microorganisms that lie at the base of the marine food chain. The survey is part of a long-term project spanning 12 years. Tiny phytoplankton species developed smaller cells that are not easily consumed by larger animals. Researchers believe this could potentially have “profound changes all the way up the food chain.” There could also be impacts on the ability of marine ecosystems to absorb - or sequester - carbon and the size of fish stocks. The study’s lead author Mark Brown tells VOA…

Deepfake Scam Video Cost Company $26 Million, Hong Kong Police Says

All, Business, News, Technology
Hong Kong — Scammers tricked a multinational firm out of some $26 million by impersonating senior executives using deepfake technology, Hong Kong police said Sunday, in one of the first cases of its kind in the city. Law enforcement agencies are scrambling to keep up with generative artificial intelligence, which experts say holds potential for disinformation and misuse — such as deepfake images showing people mouthing things they never said. A company employee in the Chinese finance hub received "video conference calls from someone posing as senior officers of the company requesting to transfer money to designated bank accounts," police told AFP. Police received a report of the incident on January 29, at which point some HK$200 million ($26 million) had already been lost via 15 transfers. "Investigations are still ongoing…

Russian Cosmonaut Sets Record for Total Time in Space

All, News
Mosocw — Russian cosmonaut Oleg Kononenko on Sunday set a world record for total time spent in space, surpassing his compatriot Gennady Padalka who logged more than 878 days in orbit, Russia's space corporation said. At 0830 GMT Kononenko broke the record, Roscosmos said. Kononenko is expected to reach a total of 1,000 days in space on June 5 and by late September he will have clocked 1,110 days. "I fly into space to do my favorite thing, not to set records," Kononenko told TASS in an interview from the International Space Station (ISS) where he is orbiting about 263 miles (423 km) from Earth. "I am proud of all my achievements, but I am more proud that the record for the total duration of human stay in space is still…

Crane Who Fell for Keeper Dies at 42

All, News
WASHINGTON — One of the great interspecies love stories of our time has come to an end. Walnut, a white-naped crane and internet celebrity, has died at age 42. She is survived by eight chicks, the loving staff at the Smithsonian's National Zoo and Conservation Biology Institute and by Chris Crowe, a human zookeeper whom Walnut regarded as her mate for nearly 20 years. "Walnut was a unique individual with a vivacious personality," Crowe said, in a statement released by the National Zoo. "I'll always be grateful for her bond with me." The tale of Walnut (and Chris) has inspired internet fame and the occasional love song. It dates back to the bird's 2004 arrival at the institute's campus in Front Royal, Virginia. The chick of two wild cranes who had…

Who Freed Flaco? Owl’s Escape From New York Zoo Remains a Mystery

All, News
new york — This New York love story begins with a criminal act of sabotage.  Under cover of darkness a year ago Friday, someone breached a waist-high fence and slipped into the Central Park Zoo. Once inside, they cut a hole through a steel mesh cage, freeing a majestic Eurasian eagle-owl named Flaco who had arrived at the zoo as a fledgling 13 years earlier.  Immediately, Flaco fled the park, blinking his big orange eyes at pedestrians and police on Fifth Avenue before flying off into the night.  In the year since his dramatic escape, Flaco has become one of the city's most beloved characters. By day he lounges in Manhattan's courtyards and parks or perches on fire escapes. He spends his nights hooting atop water towers and preying on the…

China Launches Rocket as Commercial Missions Pick Up Pace

All, Business, News, Technology
BEIJING — A small but powerful Chinese rocket capable of carrying payloads at competitive costs delivered nine satellites into orbit Saturday, Chinese state media reported, in what is gearing up to be another busy year for Chinese commercial launches.  The Jielong-3, or Smart Dragon-3, blasted off from a floating barge off the coast of Yangjiang in southern Guangdong province, the second launch of the rocket in just two months.  Developed by China Rocket Company, a commercial offshoot of a state-owned launch vehicle manufacturer, Jielong-3 made its first flight in December 2022.  President Xi Jinping has called for the expansion of strategic industries including the commercial space sector, deemed key to building constellations of satellites for communications, remote sensing and navigation.  Also Saturday, Chinese automaker Geely Holding Group launched 11 satellites to…

X Chromosome Linked to Autoimmune Diseases

All, News
WASHINGTON — Women are far more likely than men to get autoimmune diseases, when an out-of-whack immune system attacks their own bodies — and new research may finally explain why. It's all about how the body handles females' extra X chromosome, Stanford University researchers reported Thursday — a finding that could lead to better ways to detect a long list of diseases that are hard to diagnose and treat. "This transforms the way we think about this whole process of autoimmunity, especially the male-female bias," said University of Pennsylvania immunologist E. John Wherry, who wasn't involved in the study. More than 24 million Americans, by some estimates up to 50 million, have an autoimmune disorder — diseases such as lupus, rheumatoid arthritis, multiple sclerosis and dozens more. About 4 of every…

Residents Japanese Nuclear Plant Damaged in Quake Examined

All, News
TOKYO — A group of residents of towns near Japanese nuclear plants submitted a petition on Friday asking regulators to halt safety screening for the restart of idled reactors until damage to a plant that partially lost external power and spilled radioactive water during a recent powerful earthquake is fully examined. The magnitude 7.6 quake on New Year's Day and dozens of strong aftershocks in north-central Ishikawa prefecture left 240 people dead and 15 unaccounted for and triggered a small tsunami. Two idled reactors at Shika nuclear power plant on the Noto Peninsula in Ishikawa suffered power outages because of damage to transformers. Radioactive water spilled from spent fuel cooling pools and cracks appeared on the ground, but no radiation leaked outside, operator Hokuriku Electric Power Co. said. The damage rekindled…

Beheading Video Gone from YouTube, But Questions Remain

All, Business, News, Technology
NEW YORK — A graphic video from a Pennsylvania man accused of beheading his father that circulated for hours on YouTube has put a spotlight yet again on gaps in social media companies' ability to prevent horrific postings from spreading across the web. Police said Wednesday that they charged Justin Mohn, 32, with first-degree murder and abusing a corpse after he beheaded his father, Michael, in their Bucks County home and publicized it in a 14-minute YouTube video that anyone, anywhere could see. News of the incident — which drew comparisons to the beheading videos posted online by the Islamic State militants at the height of their prominence nearly a decade ago — came as the CEOs of Meta, TikTok and other social media companies were testifying in front of federal…

US Hurricane Center’s Forecasts to Expand to Include Inland Areas

All, News
ST. PETERSBURG, Florida — The "cone of uncertainty" produced by the National Hurricane Center to forecast the location and ferocity of a tropical storm is getting an update this year to include predictions for inland areas, where wind and flooding are sometimes more treacherous than damage to the coasts.  The Miami-based hurricane center said Thursday on the X social media platform that the new, experimental forecast tool will be ready around August 15, just before the traditional peak of the hurricane season that begins June 1.  "This experimental graphic will help better convey wind hazard risk inland in addition to coastal wind hazards," the center said in the post.  The traditional cone in use for years generally shows the forecast track of a hurricane or tropical storm but is focused on…

Lunar Night Puts Japan’s Lander Back to Sleep

All, Business, News, Technology
TOKYO — After a brief awakening, Japan's Moon lander is out of action again but will resume its mission if it survives the two-week lunar night, the space agency said Thursday. The unmanned Smart Lander for Investigating Moon (SLIM) touched down last month at a wonky angle that left its solar panels facing the wrong way. As the sun's angle shifted, it came back to life for two days this week and carried out scientific observations of a crater with its high-spec camera. "After completing operation from 1/30 (to) 1/31, #SLIM entered a two-week dormancy period during the long lunar night," space agency JAXA said on X, formerly Twitter. "Although SLIM was not designed for the harsh lunar nights, we plan to try to operate again from mid-February, when the Sun…

Staggering Rise in New Cancer Cases Projected in 2050  

All, News
Geneva — New cancer cases are projected to rise by 77% to more than 35 million in 2050 from an estimated 20 million new cases and 9.7 million deaths in 2022, according to new data released Thursday by the World Health Organization’s cancer agency, the International Agency for Research on Cancer (IARC). The report, which is being issued ahead of World Cancer Day February 4, projects the greatest relative increases in cancer cases will occur in lower human development index (HDI) settings.
