Shape memory achieved for nano-sized objects

Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for example in generators or hydraulic ...

NASA selects futuristic space technology concepts for early study

An astronaut steps into a body scanner and, hours later, walks on Mars in a custom-made spacesuit, breathing oxygen that was extracted from Mars' carbon dioxide-rich atmosphere. On Venus, an inflatable bird-like drone swoops ...

Titan's river maps may advise Dragonfly's sedimental journey

With future space exploration in mind, a Cornell-led team of astronomers has published the final maps of Titan's liquid methane rivers and tributaries—as seen by NASA's late Cassini mission—so that may help provide context ...
