Exotic carbon microcrystals in meteorite dust

Unusually shaped microcrystals formed of pure, graphite-like carbon were discovered in the dust of the 21st-century's largest meteorite. They are likely to have grown in layers from complex carbon nuclei such as fullerene.

A novel Raman chemical sensor made from noodlelike threads of gold

Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical ...

Diagnosing jaundice using tear fluids

Human tear fluids contain many proteins, metabolites, and other molecules whose concentrations change significantly with certain diseases. A research team has now developed a handy test kit for tears that can identify patients ...
