Using lasers to cool and manipulate molecules

(PhysOrg.com) -- "For years, we have been using laser cooling to trap and manipulate atoms," David DeMille tells PhysOrg.com. "This has been very useful for both basic science and many applications. Recently there has been great interest in cooling and trapping molecules as well. Their rich internal structure makes molecules useful for a wide range of new experiments and possible applications."

192 nations at UN climate conference in Copenhagen

(AP) -- The largest and most important U.N. climate change conference in history opened Monday, with organizers warning diplomats from 192 nations that this could be the best, last chance for a deal to protect the world from calamitous global warming.

Google Chrome extensions to be officially released

(PhysOrg.com) -- Google is expected to release its Extensions Gallery for general users of the new Chrome browser this week, possibly at the Add-On Conference on browser extensions to be held on December 11, 2009. Google is a platinum sponsor of the conference. An extensions site was unveiled a couple of weeks ago, but only for the use of developers.

Silicon Valley getting greener with Hara

Fresh from signing on to help green Silicon Valley, startup Hara will be at climate talks in Copenhagen this week to urge that corporations not wait for regulations to fight global warming.

Tiny RNA has big impact on lung cancer tumors

Researchers from Yale University and Mirna Therapeutics, Inc., reversed the growth of lung tumors in mice using a naturally occurring tumor suppressor microRNA. The study reveals that a tiny bit of RNA may one day play a big role in cancer treatment, and provides hope for future patients battling one of the most prevalent and difficult to treat cancers.

Now where was I again?

Although the actual interruption may only last a few moments, the study shows that we then lose more time when we try to find our place and resume the task that was interrupted.

NASA to launch sky-mapping spacecraft

(AP) -- NASA's latest space telescope will scan the sky in search of never-before-seen asteroids, comets, stars and galaxies, with one of its main tasks to catalog objects posing a danger to Earth. The sky-mapping WISE, or Wide-Field Infrared Survey Explorer, is scheduled to launch no earlier than before dawn Friday from Vandenberg Air Force Base on the central California coast aboard a Delta 2...

'Rational drug design' identifies fragments of FDA-approved drugs relevant to emerging viruses

A massive, data-crunching computer search program that matches fragments of potential drug molecules to the known shapes of viral surface proteins has identified several FDA-approved drugs that could be the basis for new medicines -- if emerging viruses such as the H5N1(avian flu) or H1N1/09 (swine flu) develop resistance to current antiviral therapies -- according to a presentation at the...

Scientists build 'single-atom transistor'

(PhysOrg.com) -- Researchers from Helsinki University of Technology (Finland), University of New South Wales (Australia), and University of Melbourne (Australia) have succeeded in building a working transistor, whose active region composes only of a single phosphorus atom in silicon. The results have just been published in Nano Letters.

Wolf recovery at crossroads in the Southwest

(AP) -- A decade has passed since the federal government began releasing Mexican wolves into the wild in an effort to return the endangered animal to its historic range in the Southwest. It hasn't worked out - for the wolves, for ranchers, for conservationists or for federal biologists.
