Discarded data may hold the key to a sharper view of molecules

May 25, 2012 5:12 am | News | Comments

There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments. The findings could lead to new understanding of the molecules that drive processes in biology, medical diagnostics, nanotechnology, and other fields.

When nanoparticles become “artificial atoms”

May 24, 2012 12:07 pm | by Lynn Yarris | News | Comments

The contention of a major but controversial new theory to explain nanocrystal growth is that nanoparticles can act as “artificial atoms,” forming molecular-type building blocks that can assemble into complex structures. The conclusion is based on recent observations of growing nanorods made by Lawrence Berkeley National Laoratory researchers using transmission electron microscopy and advanced liquid cell handling techniques.

Exotic particles, chilled and trapped, form giant matter wave

May 24, 2012 7:17 am | News | Comments

Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave. This feat will allow scientists to better study the physical properties of excitons, which exist only fleetingly yet offer promising applications as diverse as efficient harvesting of solar energy and ultrafast computing.

'Negative leakage' could be key to reducing carbon emissions

May 24, 2012 6:54 am | News | Comments

The unilateral efforts of a single country or region to reduce the emissions of greenhouse gases could reduce exports, increase imports and lead to higher emissions elsewhere—what economists call "leakage." Unilateral efforts could, however, work better if other sources of energy were used as substitutes, thereby creating "negative leakage," according to research by University of Illinois energy policy experts.

A wake-up call for manufacturing

May 24, 2012 6:42 am | News | Comments

U.S. factories produce about 75% of what the country consumes, but the right decisions by both business and political leaders could push that to 95%, say University of Michigan researchers.
