Computer memory could one day withstand the blazing temperatures in fusion reactors, jet engines, geothermal wells and sweltering planets using a new solid-state memory device developed by a team of engineers led by the University of Michigan.

Unlike conventional silicon-based memory, the new device can store and rewrite information at temperatures over 1,100°F (600°C)—hotter than the surface of Venus and the melting temperature of lead. It was developed in collaboration with researchers at Sandia National Laboratory.

“It could enable electronic devices that didn’t exist for high-tempera...

The first dark comet—a celestial object that looks like an asteroid but moves through space like a comet—was reported less than two years ago. Soon after, another six were found...

A team of roboticists at the Beijing Institute of Technology, working with a pair of colleagues from the Technical University of Munich, has created a new kind of rat robot—one that was designed to interact in social ways with real rats.

In their paper published in the journal Nature Machine Intelligence, the group describes how they used artificial intelligence to train their robot rat to behave like a real rat...
