A new study on the absence of liquid water on the surface of Mars has suggested that an easy escape route of hydrogen from the high altitude upper atmosphere is one of the major reasons. In the study, ...

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, ...

Scientists have long believed that Mars lost its liquid water very gradually, turning into a mostly dry planet over an extremely long time frame. However, they may have to toss that assumption out the ...

Scientists have developed a strange new material that can quickly flip between a liquid and a solid state – all thanks to magnets. In a scene that wouldn’t look out of place in James Cameron’s ...

A shape-shifting robot can liquefy itself and reform, allowing it to reach hard-to-access places. Scientists say it could eventually serve as a hands-free tool for extracting swallowed toxic items.
