New technique to see neurons of the deep brain for months at a time developed at Stanford
Travel just one millimeter inside the brain and you’ll be stepping into the dark.
Standard light microscopes don’t allow researchers to look into the interior of the living brain, where memories are formed and diseases such as dementia and can…
Scripps Research chemist devises new method to quantify protein changes
JUPITER, FL, January 5, 2011 — A scientist from the Florida campus of The Scripps Research Institute has devised a new method of analyzing and quantifying changes in proteins that result from a common chemical process. The new findings could provi…
Reading ‘Avatar’s’ DNA
Tel Aviv — You know when you’re watching a pirated film downloaded from the Internet — there’s no mistaking the fuzzy footage, or the guy in the front row getting up for popcorn. Despite the poor quality, pirated video is a serious problem a…
New method for making tiny catalysts holds promise for air quality
CHAMPAIGN, Ill. — Fortified with iron: It’s not just for breakfast cereal anymore. University of Illinois researchers have demonstrated a simpler method of adding iron to tiny carbon spheres to create catalytic materials that have the potenti…
Nanoscale gene ‘ignition switch’ may help spot and treat cancer
In a proof of principal study in mice, scientists at Johns Hopkins and the Virginia Commonwealth University (VCU) have shown that a set of genetic instructions encased in a nanoparticle can be used as an “ignition switch” to rev up gene activity tha…
UGA researchers develop rapid diagnostic test for common type of pneumonia
Athens, Ga. — University of Georgia researchers have developed a technique that can diagnose a common type of pneumonia within minutes, potentially replacing existing tests that can take several days for results.
The researchers, whose findings…
