Researchers create accurate computer model of RNA tetraloop

A computational model developed by researchers at Rensselaer Polytechnic Institute is the first to accurately simulate the complex twists of a short sequence of RNA as it folds into a critical hairpin structure known as a ...

Water and ammonia factories

(PhysOrg.com) -- Complex molecules, including many organic species, exist in a wide range of environments in the cosmos, and are especially abundant in giant molecular clouds of gas and dust where new stars form. The rich ...

Decoding the molecular machine behind E. coli and cholera

Scientists from Queen Mary, University of London have discovered the workings behind some of the bacteria that kill hundreds of thousands every year, possibly paving the way for new antibiotics that could treat infections ...

Scientists 'fingerprint' nanoscale objects and viruses

Spanish scientists at the University of Barcelona have found a way of effectively identifying nanoscale objects and viruses that could offer a breakthrough for biomedical diagnostics, environmental protection and nano-electronics

How to look for a few good catalysts

Two key physical phenomena take place at the surfaces of materials: catalysis and wetting. A catalyst enhances the rate of chemical reactions; wetting refers to how liquids spread across a surface.
