Building blocks of life can form long before stars

An international team of scientists have shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space.

Record efficiency for perovskite-based light-emitting diodes

Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6 percent, which is a record. The results have been published ...

Hot off the press: Nanoscale Gutenberg-style printing

(PhysOrg.com) -- When Gutenberg developed the principles of modern book printing, books became available to the masses. Hoping to bring technology capable of mass production to the nanometer scale, Udo Bach and this team ...

A Neandertal from Chagyrskaya Cave

The researchers extracted the DNA from bone powder and sequenced it to high quality. They estimate that the female Neandertal lived 60,000-80,000 years ago. From the variation in the genome they estimate that she and other ...

Smart materials: Fused liquid marbles show their strength

'Liquid marbles' are a peculiar new substance made by rolling water droplets into powders incapable of dissolving in water. The resulting micro- and nanoscale-particles act like soft solids, and can speed along surfaces without ...

Glowing flowers for ultra-trace analysis of TNT

(Phys.org)—Highly sensitive and highly selective tests are important for the early detection of disease, the detection of environmental toxins, or for the detection of explosives at airports. Increased selectivity for the ...
