Today's physics/chemistry headlines from the sources selected by our team:

Cold Atom Laboratory creates atomic dance
Like dancers in a chorus line, atoms' movements become synchronized when lowered to extremely cold temperatures. To study this bizarre phenomenon, called a Bose-Einstein condensate, researchers need to cool atoms to a temperature just above absolute zero - the point at which atoms have the least energy and are close to motionless.

Scientists create possible precursor to life
How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.

Strengthening thin-film bonds with ultrafast data collection
When studying extremely fast reactions in ultrathin materials, two measurements are better than one. A new research tool invented by researchers at Lawrence Livermore National Laboratory (LLNL), Johns Hopkins University and the National Institute of Standards and Technology (NIST) captures information about both temperature and crystal structure during extremely fast reactions in thin-film materials.

Superconducting circuits, simplified
Computer chips with superconducting circuits—circuits with zero electrical resistance—would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet's most popular sites.

Wild molecular interactions in a new hydrogen mixture
Hydrogen responds to pressure and temperature extremes differently. Under ambient conditions hydrogen is a gaseous two-atom molecule. As confinement pressure increases, the molecules adopt different states of matter -- like when water ice melts to liquid. Scientists have now combined hydrogen with its heavier sibling deuterium and created a novel, disordered, 'Phase IV'-material. The molecules interact differently than have been observed before, which could be valuable for controlling superconducting and thermoelectric properties of new materials.

Crystallography: Towards controlled dislocations
Scientists have used atomic-resolution Z-contrast imaging and X-ray spectroscopy in a scanning transmission electron microscope to explore dislocations in the binary II-VI semiconductor CdTe, commercially used in thin-film photovoltaics. The results may lead to eventual improvement in the conversion efficiency of CdTe solar cells. These novel insights into atomically resolved chemical structure of dislocations have potential for understanding many more defect-based phenomena.

Physicists build reversible laser tractor beam
Physicists have built a tractor beam that can repel and attract objects, using a hollow laser beam, bright around the edges and dark in its center. It is the first long-distance optical tractor beam, 100 times larger than previous ones.

Reversible tractor beam can repel and attract objects
We're still a far cry from Star Trek's ship-towing and repelling technology, but laser physicists at the Australian National University (ANU) have built a tractor beam that can repel and attract ...

New study charts the fate of chemicals affecting health and the environment
Looking forward in science often requires looking back, evaluating trends to extrapolate future outcomes. A classic case is Moore's Law, which predicts that the density of components on an integrated ...
