A group of computer scientists once backed by Elon Musk has caused some alarm by developing an advanced artificial intelligence (AI) they say is too dangerous to release to the public. OpenAI, a research non-profit based in San Francisco, says its “chameleon-like” language prediction system, called GPT–2, will only ever see a limited release
At first glance, the two rows of portraits at the top of this article just look like a bunch of average-looking people. The catch is, none of them exist. All of these faces are fakes, put together by artificial intelligence. To be more precise, these faces are created by a generative adversarial network (GAN)
China’s Academy of Space Technology is working on an orbital power plant that would capture solar energy in space and beam it back to Earth. The plant would be able to harness solar power even when it’s cloudy back on Earth, since its photovoltaic array would be floating high above any terrestrial weather. With plans
Sleep is pretty great. In humans, evidence suggests it has a whole range of benefits, including this one: it keeps the brain healthy by letting neurons prune unnecessary synaptic connections we make during the day. This process, called synaptic homeostasis, prevents the brain from being overrun by useless memories. It’s possible that it helps to
In a sensational test of technological independence, Russia is making plans to cut off its internet from the rest of the world, with a giant ‘unplugging’ experiment that will affect over 100 million Russian internet users. The action – which the nation has boasted of doing for years – would be a temporary test,
Alarming video captured by a Twitter user in Philadelphia highlights a rare but little-known danger of electroshock Taser-style weapons. In the footage, posted on Saturday, a man is seen struggling with security guards on the street, before being fired upon with a Taser-style device. Almost instantly, the man is alight, screaming in agony as his
3D printers work by laboriously printing objects layer by layer. For larger objects, that process can take hours or even days. But now scientists at the University of California, Berkeley have found a shortcut: a printer that can fabricate objects in one shot using light – and which could, potentially, revolutionize rapid manufacturing technology.
