As smartwatches become more powerful, they will generate more heat. To prevent burns or rashes, what if a material touching the skin could feel as cool as metal, but also be flexible enough to be worn on the wrist?
When a massive star dies, first there is a supernova explosion. Then, what's left over becomes either a black hole or a neutron star.
Scientists in China and Germany have designed an artificial color-changing material that mimics chameleon skin, with luminogens (molecules that make crystals glow) organized into different core and shell hydrogel layers instead ...
Seeing through smog and fog. Mapping out a person's blood vessels while monitoring heart rate at the same time—without touching the person's skin. Seeing through silicon wafers to inspect the quality and composition of ...
Clothing, from tank tops to parkas, helps people adapt to temperatures outdoors. But you can only put on or take off so much of it, and fluctuations in weather can render what you are wearing entirely inadequate. In a new ...
Researchers at AMBER, the SFI Centre for Advanced Materials and BioEngineering Research, and from Trinity's School of Â鶹ÒùÔºics, have developed next-generation, graphene-based sensing technology using their innovative G-Putty ...
Nuclear physicists have made a new, highly accurate measurement of the thickness of the neutron "skin" that encompasses the lead nucleus in experiments conducted at the U.S. Department of Energy's Thomas Jefferson National ...
One of the evolutionary disadvantages for mammals, relative to other vertebrates like fish and chickens, is the inability to regenerate sensory hair cells. The inner hair cells in our ears are responsible for transforming ...
Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The results are published in ...
Some snake species slither across the ground, while others climb trees, dive through sand or glide across water. Today, scientists report that the surface chemistry of snake scales varies among species that negotiate these ...
