Researchers have created a new class of robots that can shift between solid and liquid forms on demand. In a series of tests, these new bots could change shape to run obstacle courses, carry objects, or even escape from a jail cell like a Terminator.

Scientists have discovered unexpected behavior in perovskite crystals that represents an entirely new state of matter, which they say can help drive the development of advanced solar cells and other optical and electronic devices.

Mundane as it may seem, glass is a surprisingly mysterious material. Now scientists at the University of Konstanz have identified a new state of matter called liquid glass, which has some unusual properties.

The eROSITA X-ray telescope will search for black holes and dark matter, and may help explain why the expansion of the universe is accelerating instead of slowing down.
