Making a better invisibility cloak with lasers

Invisibility

Nearly all technological advances in the past century or more have depended on our ability to produce and manipulate the vast variety of materials that nature has given us. Nowhere is this more evident than in the field of electronics. From a smorgasbord of semiconductors, polymers, and metals, we’ve been able to create a dazzling array of circuitry that now underpins pretty much every aspect of modern life.

Scientists are studying how squid and other cephalopods change color and pattern of their skin to blend in with their environment.

Octopuses, squid, and cuttlefish have the ability to instantaneously change the color and pattern of their skin to blend in with their surroundings.  This has caught the eye of the U.S. military and now its goal is a new generation of high-tech camouflage.

An Implantable Biosensor Could Alert Doctors to Signs of Disease

silk biosensor

A biosensor made from silk and gold can pick up tiny signals from proteins and chemicals in the body.

Silk and gold, usually a pairing for the runways of Milan, are now the main ingredients for a new kind of implantable biosensor. Researchers at Tufts University have crafted a small antenna from liquid silk and micropatterned gold. The antenna is designed to spot specific proteins and chemicals in the body, and alert doctors wirelessly to signs of disease. Scientists say the implant could someday help patients with diabetes track their glucose levels without having to test themselves daily.
