This is what a stretchy circuit looks like

Researchers in China have made a new hybrid conductive material—part elastic polymer, part liquid metal—that can be bent and stretched at will. Circuits made with this material can take most two-dimensional shapes and ...

World's smallest optical implantable biodevice

Japanese researchers have described a new implantable device no bigger than the width of a coin that can be used to control brain patterns. The device, reported in AIP Advances, converts infrared light into blue light to ...

Solving the problem of surgical stainless steel

Stainless steel is widely used in surgical medicine: for medical devices such coronary stents, hip-implant stems and spinal-disc replacements, and for a variety of surgical tools such as scalpels and forceps, as well as operating ...

Physicists predict nonmetallic half-metallicity

A team of researchers of the Russian Academy of Sciences (RAS), in collaboration with a colleague from RIKEN (Institute for Physical and Chemical Research in Japan), has provided theoretical proof of the existence of a new ...
