London — False and misleading information supercharged with cutting-edge artificial intelligence that threatens to erode democracy and polarize society is the top immediate risk to the global economy, the World Economic Forum said in a report Wednesday. In its latest Global Risks Report, the organization also said an array of environmental risks pose the biggest threats in the longer term. The report was released ahead of the annual elite gathering of CEOs and world leaders in the Swiss ski resort town of Davos and is based on a survey of nearly 1,500 experts, industry leaders and policymakers. The report listed misinformation and disinformation as the most severe risk over the next two years, highlighting how rapid advances in technology also are creating new problems or making existing ones worse. The authors worry that the boom in generative AI chatbots like ChatGPT means that creating sophisticated synthetic content that can be used to manipulate groups of people won’t be limited any longer to those with specialized skills. AI is set to be a hot topic next week at the Davos meetings, which are expected to be attended by tech company bosses including OpenAI CEO Sam Altman, Microsoft CEO Satya Nadella and AI industry players like Meta’s chief AI scientist, Yann LeCun. AI-powered misinformation and disinformation is emerging as a risk just as billions of people in a slew of countries, including large economies like the United States, Britain, Indonesia, India, Mexico, and Pakistan, are set to head to the polls this year …

WASHINGTON — A recent cyber kidnapping incident involving a Chinese exchange student in Utah appears to be part of an international pattern in which unknown perpetrators, often masquerading as Chinese police or government officials, target Chinese students around the world and extort their families for upwards of tens of thousands of dollars. In late December, 17-year-old Chinese student Kai Zhuang was reported missing near Salt Lake City, only to be found days later alone and freezing in a tent in the mountains. Authorities have said the case was part of an apparent cyber kidnapping scheme to scam his family in China out of $80,000. Cyber kidnapping is when perpetrators pretend to have abducted someone to coerce their family into paying a ransom. “At the heart of it are the heartstrings of the victim, who is told to go run and hide, and the heartstrings of the people who think their loved one is actually in the possession of kidnappers,” said Theresa Payton, CEO of cybersecurity company Fortalice Solutions. “Virtual kidnapping is, at its very root, manipulative. It is coercive. It is emotionally draining and complex,” said Payton, who is based in Charlotte, North Carolina. On January 3, just a day after Zhuang Kai was found, the FBI issued a warning about criminals impersonating Chinese police officers to defraud Chinese people based in the United States, especially Chinese students. Around the world VOA has learned that the cyber scams aren’t targeting only Chinese students studying in the United States. Over the past …

washington — The United States is pushing back its planned return of astronauts to the surface of the Moon from 2025 to 2026, NASA Administrator Bill Nelson said Tuesday. Artemis, named after the sister of Apollo in Greek mythology, was officially announced in 2017 as part of the US space agency’s plans to establish a sustained presence on Earth’s nearest space neighbor, and apply lessons learned there for a future mission to Mars. Its first mission, an uncrewed test flight to the Moon and back called Artemis 1, took place in 2022, after several postponements. Artemis 2, involving a crew that doesn’t land on the surface, has been postponed from later this year to September 2025, Nelson told reporters. Artemis 3, in which the first woman and first person of color are to set foot on lunar soil at the Moon’s south pole, should now take place in September 2026. “Safety is our top priority, and to give Artemis teams more time to work through the challenges,” said Nelson. NASA is also looking to build a lunar space station called Gateway where spacecraft will dock during later missions. Elon Musk’s SpaceX has won the contract for a landing system for Artemis 3 based on a version of its prototype Starship rocket, which remains far from ready. Both of its orbital tests have ended in explosions. Delays to Starship have knock-on effects because the spacesuit contractor needs to know how the suits will interface with the spacecraft, and simulators need to be …

Washington — Meta on Tuesday said it was tightening up content restrictions for teens on Instagram and Facebook as it faces increased scrutiny that its platforms are harmful for young people.  The changes come months after dozens of U.S. states accused Meta of damaging the mental health of children and teens, and misleading users about the safety of its platforms.  In a blog post, the company run by Mark Zuckerberg said it will now “restrict teens from seeing certain types of content across Facebook and Instagram even if it’s from friends or people they follow.”  This type of content would include content that discusses suicide or self-harm, as well as nudity or mentions of restricted goods, the company added.  Restricted goods on Instagram include tobacco products and weapons as well as alcohol, contraception, cosmetic procedures and weight loss programs, according to its website.  In addition, teens will now be defaulted into the most restricted settings on Instagram and Facebook, a policy that was in place for new users and that now will be expanded to existing users.  This will “make it more difficult for people to come across potentially sensitive content or accounts in places like Search and Explore,” the company said.  Meta also said that it will expand its policy of hiding results to searches related to suicide and self harm to include more terms. Leaked internal research from Meta, including by the Wall Street Journal and whistle-blower Frances Haugen, has shown that the company was long aware of dangers …

Cape Canaveral, Florida — The first U.S. lunar lander in more than 50 years rocketed toward the moon Monday, launching private companies on a space race to make deliveries for NASA and other customers. Astrobotic Technology’s lander caught a ride on a brand new rocket, United Launch Alliance’s Vulcan. The Vulcan streaked through the Florida predawn sky, putting the spacecraft on a roundabout route to the moon that should culminate with an attempted landing on Feb. 23. The Pittsburgh company aims to be the first private business to successfully land on the moon, something only four countries have accomplished. But a Houston company also has a lander ready to fly, and could beat it to the lunar surface, taking a more direct path. “First to launch. First to land is TBD” — to be determined, said Astrobotic chief executive John Thornton. NASA gave the two companies millions to build and fly their own lunar landers. The space agency wants the privately owned landers to scope out the place before astronauts arrive while delivering NASA tech and science experiments as well as odds and ends for other customers. Astrobotic’s contract for the Peregrine lander: $108 million. The last time the U.S. launched a moon-landing mission was in December 1972. Apollo 17’s Gene Cernan and Harrison Schmitt became the 11th and 12th men to walk on the moon, closing out an era that has remained NASA’s pinnacle. The space agency’s new Artemis program — named after the twin sister of Apollo in Greek …

Cape Canaveral, Florida — The first American spacecraft to attempt to land on the Moon in more than half a century is poised to blast off early Monday — but this time, private industry is leading the charge.   A brand-new rocket, United Launch Alliance’s Vulcan Centaur, should lift off from Cape Canaveral Space Force Station at 2:18 a.m. (7:18 GMT) for its maiden voyage, carrying Astrobotic’s Peregrine Lunar Lander. The weather so far appears favorable. If all goes to plan, Peregrine will touch down on a mid-latitude region of the Moon called Sinus Viscositatis, or Bay of Stickiness, on February 23. “Leading America back to the surface of the Moon for the first time since Apollo is a momentous honor,” Pittsburgh-based Astrobotic’s CEO John Thornton said ahead of the launch. Until now, a soft landing on Earth’s nearest celestial neighbor has only been accomplished by a handful of national space agencies: the Soviet Union was first, in 1966, followed by the United States, which is still the only country to put people on the Moon.   China has successfully landed three times over the past decade, while India was the most recent to achieve the feat on its second attempt, last year. Now, the United States is turning to the commercial sector to stimulate a broader lunar economy and ship its own hardware at a fraction of the cost, under the Commercial Lunar Payload Services (CLPS) program. A challenging task   The space agency has paid Astrobotic more than $100 …

New Delhi — India has achieved another milestone in space exploration by successfully placing a spacecraft in an orbit from which it will study the sun for five years. India joined a select group of nations already studying the sun four months after it became the first country to land an unmanned spacecraft on the moon’s southern polar region, cementing its reputation as a nation that is emerging on the frontlines of space exploration. The Indian Space Research Organization said that the space observatory, Aditya L-1, reached the position from which it can monitor the sun’s outer layer and send data back to Earth on Saturday. The spacecraft, which was launched September 2, took four months to reach its destination. “The orbit of Aditya-L1 spacecraft is a periodic Halo orbit which is located roughly 1.5 million km [kilometers] from earth,” according to an ISRO statement. Aditya-L1 is named after the Hindu god of the sun, called Aditya in Sanskrit. “L1” refers to Lagrange point 1, the location in space between the sun and Earth, where the satellite has been parked. “This demonstrates India’s capability to travel over a million kilometers away from the Earth’s orbit. It is a capability that very few countries have and India is the first in Asia to do so,” according to Chaitanya Giri, associate professor of environmental sciences at Flame University in Pune. “The ability to maintain deep space communication with a spacecraft that has traveled so far and sustain a mission for a long period …

LONDON — U.K. police have opened a fraud investigation into Britain’s Post Office over a miscarriage of justice that saw hundreds of postmasters wrongfully accused of stealing money when a faulty computer system was to blame. The Metropolitan Police force said late Friday that it is investigating “potential fraud offences arising out of these prosecutions,” relating to money the Post Office received “as a result of prosecutions or civil actions” against accused postal workers. Police also are investigating potential offenses of perjury and perverting the course of justice over investigations and prosecutions carried out by the Post Office. Between 1999 and 2015, more than 700 post office branch managers were accused of theft or fraud because computers wrongly showed that money was missing. Many were financially ruined after being forced to pay large sums to the company, and some were convicted and sent to prison. Several killed themselves. The real culprit was a defective computer accounting system called Horizon, supplied by the Japanese technology firm Fujitsu, that was installed in local Post Office branches in 1999. The Post Office maintained for years that data from Horizon was reliable and accused branch managers of dishonesty when the system showed money was missing. After years of campaigning by victims and their lawyers, the Court of Appeal quashed 39 of the convictions in 2021. A judge said the Post Office “knew there were serious issues about the reliability” of Horizon and had committed “egregious” failures of investigation and disclosure. A total of 93 of …

washington — Scientists have found a way to help Alzheimer’s drugs seep inside the brain faster — by temporarily breaching its protective shield. The novel experiment was a first attempt in just three patients. But in spots in the brain where the new technology took aim, it enhanced removal of Alzheimer’s trademark brain-clogging plaque, researchers reported Wednesday. “Our goal is to give patients a head start,” by boosting some new Alzheimer’s treatments that take a long time to work, said Dr. Ali Rezai of West Virginia University’s Rockefeller Neuroscience Institute, who led the study. At issue is what’s called the blood-brain barrier, a protective lining in blood vessels that prevents germs and other damaging substances from leaching into the brain from the bloodstream. But it also can block drugs for Alzheimer’s, tumors and other neurologic diseases, requiring higher doses for longer periods for enough to reach their target inside the brain. Now scientists are using a technology called focused ultrasound to jiggle temporary openings in that shield. They inject microscopic bubbles into the bloodstream. Next, they beam sound waves through a helmetlike device to a precise brain area. The pulses of energy vibrate the microbubbles, which loosen gaps in the barrier enough for medications to slip in. Prior small studies have found the technology can safely poke tiny holes that seal up in 48 hours. Now Rezai’s team has gone a step further — administering an Alzheimer’s drug at the same time. Some new Alzheimer’s drugs, on the market or in …
