00:46 Old AIs can’t learn new tricksAn algorithm that reactivates dormant ‘neurons’ in deep learning based AIs could help them overcome their inability to learn new things and make future systems more flexible, research has shown. AIs based on deep learning struggle to learn how to tackle new tasks indefinitely, making them less adaptable to new situations. The reasons for this are unclear, but now a team has identified that ‘resetting’ parts of the neural networks underlying these systems can allow deep learning methods to keep learning continually.Research Article: Dohare et al.News and Views: Switching between tasks can cause AI to lose the ability to learn08:55 Research HighlightsTo stop crocodiles eating poisonous toads researchers have been making them sick, and a sacrificed child in ancient Mexico was the progeny of closely related parents.Research Highlight: How to train your crocodileResearch Highlight: DNA of child sacrificed in ancient city reveals surprising parentage11:20 Briefing ChatHow video g
