How seriously should we take biological threats from AI? (opens the original)
Read excerpt
The AI industry is suddenly rife with existential fears, with senior figures claiming it could "kill us all" within a decade. Dario Amodei, CEO of one of the world's largest AI companies, Anthropic, has called for a "slowdown" of AI development to prevent it outrunning our control. One particular fear is that AI could develop a dangerous biological agent, or a bioweapon. At the same time, biologists are showing AI can help them with useful research – including those employed at Anthropic, who ha
Fossil bones and tools from mysterious ancient human unearthed in China (opens the original)
Read excerpt
Archaeologists have found a new site containing remains of the Denisovans, a cryptic relative of early humans, in China. The findings also include thousands of bone and stone tools that can be used to glean more about the Denisovans. While the cave has been partially destroyed, thousands of fossils from the site can be studied further to learn more about ancient humans. The elusive Denisovans, extinct cousins of modern humans, have only left a few hints of their existence in the world. Their DNA
Oldest known evidence of human drug use discovered in fossil teeth (opens the original)
Read excerpt
Archaeologists have found evidence of a person who used a psychoactive drug up to 25,000 years ago. Tooth fossils in Indonesia suggest that ancient foragers in the region were sucking on betel nut, possibly as a painkiller. Human drug use is probably older than this sample, but evidence is harder to come by. Betel nut, one of the most commonly used drugs in the world, appears to have an ancient history. Fossilised remains of two people, found by archaeologists on the island of Sulawesi in Indone
Have we got dark energy wrong? NASA's new telescope may help us find out (opens the original)
Read excerpt
In the late 90s, a space telescope helped flip our understanding of the universe on its head. Data from the newly minted Hubble Space Telescope, along with a range of ground-based telescopes, showed the universe's expansion was not slowing down as previously thought. It was speeding up, driven by a shadowy phenomenon dubbed "dark energy". The astrophysicists who discovered this acceleration, including Australian Brian Schmidt, won the 2011 Nobel prize for their efforts. But data from our latest
It was a spy satellite, now NASA's new telescope is set to head into space (opens the original)
Read excerpt
This weekend, NASA plans to launch its next flagship mission into deep space. The Nancy Grace Roman Space Telescope, which started life as a spy satellite, will help find alien planets, map the universe, and possibly contribute to the collapse of a major theory in modern physics. Ami Choi, a research astrophysicist at NASA's Goddard Space Flight Center, says the telescope will help make discoveries in dark energy and dark matter. But, as previous space telescopes have done, it may find things th
