Taking lithium-ion batteries to new extremes

Just like Goldilocks and her proverbial porridge, lithium-ion batteries (LIBs) perform best when the temperature range is just right—that is, neither too hot nor too cold. But this is a huge limiting factor when it comes ...

This 'squidbot' jets around and takes pics of coral and fish

Engineers at the University of California San Diego have built a squid-like robot that can swim untethered, propelling itself by generating jets of water. The robot carries its own power source inside its body. It can also ...
