Recursive self-improvement, where AI continuously builds better versions of itself, might be harder than some hope.

Floating in a warm, nutritious bath, the slices of mouse brain buzzed with electrical activity. Researchers gave them a few zaps, and parts of the hippocampus strengthened their wiring. This type of ...

Increasingly, companies are building humanoid robots that perform impressive athletic feats to mark the field’s progress. Now, Chinese robotics company Unitree says its new "Superman" robot can run 12 ...
