Physicists will soon have a better measure of the age of our galaxy, thanks to experiments described in a trio of papers appearing in the journal Physical…
The data Lawler analyzed have been available for several years, but have not been well understood until now. “The pattern looked so mysterious and…
Trapping light means either stopping the light temporally or confining the light in space. Scientists have also been able to trap a light pulse in a tiny…
The new model addresses both cylindrical pores and tapering pores that simulate the á–hemolysin membrane channel. “Current models do not take into account the…
“The goal of this work is to provide a test case for quantum dynamics theory,” says author Kenneth C. Janda of the University of California, Irvine. “It is a…
Vincent Chevrier, a research professor in the Arkansas Center for Space and Planetary Sciences, will work with graduate student Jennifer Hanley to analyze data…
The resulting discovery of dark energy and the accelerating universe rewrote our understanding of the cosmos. Yet the origin of these supernovae, which have…
A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical,…
Galaxies like our own were built billions of years ago from a deluge of giant clouds of gas, some of which continue to rain down. Now new calculations tie the…
Rice physicist Junichiro Kono and his team have been studying the Aharonov-Bohm effect — the interaction between electrically charged particles and magnetic…
Described in a forthcoming issue of Physical Review Letters,* the new device is a 1-millimeter-square ion trap with a built-in optical fiber. The authors use…
Described in Nature Physics,* the new research lends more support to the idea that JILA studies of superfluidity (flow with zero friction) in atomic gases may…
The proton – one of the universal building-blocks of all matter – is even smaller than had previously been assumed (Nature, 8 July 2010). This is the result…
The dark cloud is part of the larger, parent nebula known as M17, a vast region of our galaxy with a bright, central star cluster. “We believe we've managed to…
Star Trek fans will remember “tractor beams,” lasers that allowed the Starship Enterprise to trap and move objects. Tel Aviv University is now turning this…
This environment is not as peaceful as it looks. Ultraviolet radiation and violent stellar winds have blown out an enormous cavity in the gas and dust…
