Yoshua Bengio, considered by many to be one of the godfathers of AI, has long been at the forefront of machine-learning research . However, his opinions on the technology have shifted in recent years — he joins us to talk about ways to address the risks posed by AI, and his efforts to develop an AI with safety built in

00:45 A coronal mass ejection from a distant star Researchers have detected what they say is the strongest evidence yet of a coronal mass ejection (CME) coming from a star other than our Sun. CMEs are massive bursts of fast-moving plasma that can be detected thanks to the characteristic radio signal they produce. Howev

00:45 The debate around Nanotyrannus A hotly debated species of dinosaur, assumed by many to be a juvenile T. rex, is actually a separate species, according to new research. Nanotyrannus was a dinosaur anatomically similar to T. rex, but about a tenth of the size, leading many to argue it was a young version of the ico

00:47 How bowhead whales live so long Researchers have uncovered a protein that enhances DNA repair and may explain how bowhead whales can live more than 200 years. The protein, cold-induced RNA-binding protein, was shown to enhance repair of double stranded DNA breaks, a particularly troublesome kind of damage. The te

Advice on how to get good sleep is everywhere, with the market for sleep aids worth more than US$100 billion annually. However, scientists warn that online hacks and pricey tools aren’t always effective, and suggest that lessons learnt about the workings of a network of biological clocks found in the human body could u

00:48 How hunger, hormones and aggression interact in mouse brains Researchers have uncovered the neural mechanisms that underlie an aggressive behaviour in mice prompted by hunger and hormonal state. Virgin female mice can become aggressive towards mouse pups when they are food deprived, but it seems that the relevant
