Little robots shaped like staples called "smarticles" can't move around on their own, but researchers have now found that they can randomly form structures with other robots to move about
Lithium-ion batteries often lose their charge at sub-zero temperatures, but a design incorporating bumps into one of the main components makes them work much better
A few particles of light bouncing off a flying mirror made of charged particles may reveal whether or not black holes destroy information, a famous problem in physics
