(PhysOrg.com) -- Nanowires can be grown in many ways, but one of the lesser-understood growth processes is vapor-liquid-solid (VLS) growth. In VLS, a vapor adsorbs onto a liquid droplet, and the droplet transports the vapor ...
Researchers from Indiana University School of Medicine have discovered a molecular "clamping" mechanism within a male-specific protein-DNA complex whose mutation causes sex reversal: children with XY chromosomes but female ...

A team of chemists at the University of California, Berkeley, working with a group at Merck & Co. Inc. has developed a reaction that can be used to remove a single sulfur, nitrogen or oxygen atom from a six-membered ring ...
The outer planets of our solar system, Uranus and Neptune, are water-rich gas giants. These planets have extreme pressures 2 million times the Earth's atmosphere. They also have interiors as hot as the surface of the sun. ...
