To Be Energy-Efficient, Brains Predict Their Perceptions
Results from neural networks support the idea that brains are “prediction machines” — and that they work that way to conserve energy.
Radioactivity May Fuel Life Deep Underground and Inside Other Worlds
New work suggests that the radiolytic splitting of water supports giant subsurface ecosystems of life on Earth — and could do it elsewhere, too.
New Clues to Chemical Origins of Metabolism at Dawn of Life
The ingredients for reactions ancestral to metabolism could have formed very easily in the primordial soup, new work suggests.
Swarming Bacteria Create an ‘Impossible’ Superfluid
Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry.
