Scientists and tech industry leaders, including executives at Microsoft and Google, have issued a new warning about the perils that artificial intelligence poses to humankind

A meteorite which smashed into earth 29m years ago may be behind a strange yellow glass found in a certain part of the desert in southeast Libya and southwestern Egypt, according to researchers. The Great Sand Sea Desert stretches over about 72,000 square kilometres across the two countries, and is the only place where the mysterious yellow material is found on Earth. Researchers first described it in a 1933 scientific paper, calling it Libyan desert glass. Mineral collectors have long valued it for its beauty and mysterious qualities – and it was even found in a pendant in Egyptian pharaoh Tutankhamun’s tomb. The origin of the glass has been a mystery for centuries, but researchers writing in the journal De Gruyter used new advanced microscopy technology to get answers. Elizaveta Kovaleva, a lecturer at the University of the Western Cape, wrote that the glass was caused by “the impact of a meteorite on the Earth's surface”. Writing in The Conversation, she said: “Space collisions are a primary process in the solar system, as planets and their natural satellites accreted via the asteroids and planet embryos (also called planetesimals) colliding with each other. These impacts helped our planet to assemble, too.” She said: “We studied the samples with a state-of-the-art transmission electron microscopy technique, which allows us to see tiny particles of material – 20,000 times smaller than the thickness of a paper sheet. “Using this super-high magnification technique, we found small minerals in this glass: different types of zirconium oxide (ZrO₂).” One of the types of this mineral found in the glass can only form at temperatures between 2,250 celsius and 2,700 celsius. Toasty. Kovaleva said: “Such conditions can only be obtained in the Earth's crust by a meteorite impact or the explosion of an atomic bomb.” However, she wrote, there are just as many questions as there are answers. The nearest known meteorite craters are too far away and too small to be the cause of that much glass all concentrated in one part of the world. “So, while we've solved part of the mystery, more questions remain. Where is the parental crater? How big is it – and where is it? Could it have been eroded, deformed or covered by sand?” Safe to say, the scientists will keep on looking until they have the answers.

LINDON, Utah--(BUSINESS WIRE)--Sep 14, 2023--

Elon Musk’s X, formerly known as Twitter, slowed down access to rivals and news organisations, according to a new report. The company seemingly added a delay of as long as five seconds when people clicked on links to go elsewhere on the web, according to a Washington Post report. The delay was applied to a host of rival websites, including Facebook, Instagram and Bluesky. It was also used on the websites of news organisations that have been critical of Mr Musk, such as Reuters and the New York Times. Clicking a link on X to one of the affected websites resulted in a delay of about five seconds before the webpage loaded, the Washington Post reported, citing tests it conducted on Tuesday. Reuters also saw a similar delay in tests it ran. By late Tuesday afternoon, X appeared to have eliminated the delay. When contacted for comment, X confirmed the delay was removed but did not elaborate. Billionaire ElonMusk, who bought Twitter in October, has previously lashed out at news organizations and journalists who have reported critically on his companies, which include Tesla and SpaceX. Twitter has previously prevented users from posting links to competing social media platforms. Reuters could not establish the precise time when X began delaying links to some websites. A user on Hacker News, a tech forum, posted about the delay earlier on Tuesday and wrote that X began delaying links to the New York Times on Aug. 4. On that day, Musk criticized the publication’s coverage of South Africa and accused it of supporting calls for genocide. Reuters has no evidence that the two events are related. A spokesperson for the New York Times said it has not received an explanation from X about the link delay. “While we don’t know the rationale behind the application of this time delay, we would be concerned by targeted pressure applied to any news organization for unclear reasons,” the spokesperson said on Tuesday. A Reuters spokesperson said: “We are aware of the report in the Washington Post of a delay in opening links to Reuters stories on X. We are looking into the matter.” Bluesky, an X rival that has Twitter co-founder Jack Dorsey on its board, did not reply to a request for comment. Meta, which owns Facebook and Instagram, did not immediately respond to a request for comment.
