Open-sourcing of protein-structure software is already paying off

Enlarge (credit: Humphreys et. al.) It is now relatively trivial to determine the order of amino acids in a protein. Figuring out how that order translates to a complicated three-dimensional structure that performs a specific function, however, is extremely challenging. But after decades of slow progress, Google’s DeepMind AI group announced that it has made tremendous […]

These virtual obstacle courses help real robots learn to walk

A clip from the simulation where virtual robots learn to climb steps. An army of more than 4, 000 marching doglike robots is a vaguely menacing sight, even in a simulation. But it may point the way for machines to learn new tricks. The virtual robot army was developed by researchers from ETH Zurich in […]

A new formula may help black patients’ access to kidney care

Enlarge (credit: Getty Images) For decades, doctors and hospitals saw kidney patients differently based on their race. A standard equation for estimating kidney function applied a correction for Black patients that made their health appear rosier, inhibiting access to transplants and other treatments. On Thursday, a task force assembled by two leading kidney care societies […]

Now that machines can learn, can they unlearn?

Enlarge (credit: Andriy Onufriyenko | Getty Images) Companies of all kinds use machine learning to analyze people’s desires, dislikes, or faces. Some researchers are now asking a different question: How can we make machines forget? A nascent area of computer science dubbed machine unlearning seeks ways to induce selective amnesia in artificial intelligence software. The […]
