Yeasts on plums have a plus side

Some naturally occurring yeasts may be useful for protecting stone fruits against pathogens that attack after harvest. Scientists at the U.S. Department of Agriculture (USDA) looked to the microflora on the surface of the ...

Researchers design metamaterial that buckles selectively

Researchers from Leiden University, the Netherlands, have designed a novel metamaterial that buckles on demand. Small structural variations in the material single out regions that buckle selectively under external stress, ...

Archaeologist resurfaces stories from a sunken slave ship

A Portuguese ship carrying more than 400 enslaved people left Mozambique on Dec. 3, 1794, and set sail for Brazil, where the growing sugar economy demanded cheap labor. Shackled and packed like cargo beneath the ship's deck, ...

A celestial butterfly emerges from its dusty cocoon

Some of the sharpest images ever made with ESO's Very Large Telescope have, for the first time, revealed what appears to be an ageing star giving birth to a butterfly-like planetary nebula. These observations of the red giant ...

Physicists develop ultrasensitive nanomechanical biosensor

Two young researchers working at the MIPT Laboratory of Nanooptics and Plasmonics, Dmitry Fedyanin and Yury Stebunov, have developed an ultracompact, highly sensitive nanomechanical sensor for analyzing the chemical composition ...
