Scientists create diodes made of light

Photonics researchers at the National Physical Laboratory (NPL) have achieved the extra-ordinary by creating a diode consisting of light that can be used, for the first time, in miniaturised photonic circuits, as published ...

Wheat gluten found to restore bonds in brittle human hair

A team of researchers from Jiangnan University in China and the University of Nebraska in the U.S. has found that integrating wheat gluten into a shampoo helps restore bonds, making hair less brittle. In their paper published ...

Black bears on the move in upstate New York

The black bear population in southern New York has grown and expanded their range since the early 1990s, which has led to increased encounters with humans. But details about bear populations in the state have remained understudied.

New dye allows super-imaging of cells

A new dye might allow researchers to view natural processes in extremely small components of living cells over a prolonged period of time; a previously unattainable feat.

Three layers of graphene reveals a new kind of magnet

Metals have a large density of electrons and to be able to see the wave nature of electrons one has to make metallic wires that are only a few atoms wide. However, in graphene - one atom thick graphite—the density of electrons ...

Strength of hair inspires new materials for body armor

In a new study, researchers at the University of California San Diego investigate why hair is incredibly strong and resistant to breaking. The findings could lead to the development of new materials for body armor and help ...
