Tens of thousands of years ago, prehistoric humans in Europe adorned themselves with such a wide variety of beads that researchers have classified nine distinct cultural groups across the continent based on their location and distinctive styles. The researchers focused on the Gravettian period, which stretched between 34,000 and 24,000 years ago and was defined … Read more
Scientists have built a qubit, or quantum bit, that can achieve “quantum coherence” at room temperature — something normally only possible at temperatures close to absolute zero. To achieve quantum coherence — a stable state in which the weird laws of quantum mechanics can be observed — qubits must normally be cooled down to minus … Read more
NASA’s Perseverance rover has found that Mars’ Jezero crater was at one point filled with water, offering a tantalizing hope that it may have already unearthed fossilized life on the planet. The rover, which first touched down on the crater in February 2021 along with its now-retired helicopter companion Ingenuity, made the discovery using ground-penetrating … Read more
When NASA attempted to return to the Moon for the first time in 50 years on January 8, more was at risk than just US$108 million worth of development and equipment. The agency earned the ire of the Native American Navajo people, who made a bid to stop the launch because of an unusual inclusion … Read more
Artificial intelligence (AI) systems that were trained to be secretly malicious resisted state-of-the-art safety methods designed to “purge” them of dishonesty, a disturbing new study found. Researchers programmed various large language models (LLMs) — generative AI systems similar to ChatGPT — to behave maliciously. Then, they tried to remove this behavior by applying several safety … Read more
Did someone leave a communicator badge lying on Mars? NASA’s long-running Curiosity rover mission just spotted a familiar shape to “Star Trek” fans: The iconic delta-shaped emblem that Starfleet officers typically wear on their uniforms. Unfortunately, it would be highly illogical to say that a Starfleet landing party walked near Curiosity’s roving grounds, as the … Read more
Conservators at National Museums Scotland have reconstructed a 1,800-year-old segment of Roman armor that was broken into more than 100 pieces. The completed work will be part of an upcoming exhibition. For several weeks, museum conservators painstakingly pieced together what they’re calling an “ancient jigsaw puzzle.” The second-century brass armor was shattered into dozens of … Read more
Several children born with a rare, inherited form of deafness can now hear thanks to two new gene therapies, clinical trial results show. Both therapies target the gene for otoferlin, a protein in the inner ear that lets nerve cells translate vibrations from sound into electrical signals that can be interpreted by the brain. Mutations … Read more
Chinese scientists have built a nuclear battery that can produce power for up to 50 years without being recharged. The technology, which contains a radioactive isotope, or version of nickel, as its power source, will be the first of its kind available for general purchase, Betavolt representatives said on Jan. 8 in a translated statement. … Read more
An archaeologist in Ireland has discovered an ancient megalithic tomb — one that was seen and sketched in the 19th century but then lost for almost 200 years. Local scholar Billy Mag Fhloinn, an archaeologist and folklorist with Sacred Heart University in the Irish town of Dingle, found the tomb with the help of photogrammetry, … Read more
