New physical phenomenon will likely impact atomic physics, chemistry and nanotechnology

In a discovery that is likely to impact fields as diverse as atomic physics, chemistry and nanotechnology, researchers have identified a new physical phenomenon, electrostatic rotation, that, in the absence of friction, leads to spin. Because the electric force is one of the fundamental forces of nature, this leap forward in understanding may help reveal how the smallest building blocks in nature r

Results of a study by researchers at Dartmouth-Hitchcock Medical Center (DHMC) and Dartmouth Thayer School of Engineering could have implications for choosing which patients with abdominal aortic aneurysms should have surgery and which ones should simply have follow-up with noninvasive studies.

In an article published in the April issue of the Journal of Vascular Surgery, Dr. Mark Fillinger and colleagues describe a new noninvasive method for evaluating abdominal aortic aneurysms (AAA). Th

Scientists Identify a Protein Channel that Mediates the Body’s Ability to Feel Frigid

A group of researchers from The Scripps Research Institute (TSRI) and the Genomics Institute of the Novartis Research Foundation (GNF) have identified and isolated a novel protein that mediates the body’s ability to sense cold through the skin.

In an article that will appear in this week’s issue of the journal Cell, the group describes the “ion channel” protein, called ANKTM1, which is the

Andrei Linde lauds the new era of precision cosmology

For most of us, “inflation” is a term that comes up only in conversations about the economy or flat tires. But for many cosmologists, inflation is the ultimate word in understanding how the universe was created.

In the beginning, according to inflation theory, the universe was tinier than an atom. Then, in an unimaginably brief period of time – .00000000000000000000000000000001 second, to be precise – it expanded (“inflat

Study shows surprisingly sophisticated nesting behavior in common marsh birds

Coots, the Rodney Dangerfields of the bird world, just might start to get some respect as a result of a new study showing that these common marsh birds are able to recognize and count their own eggs, even in the presence of eggs laid by other birds.

The counting ability of female coots is part of a sophisticated set of defense mechanisms used to thwart other coots who lay eggs in their neighbors&#1

Ammonia is a problem. All animal cells produce it, but how do they get rid of it? New research by Dr Dirk Weihrauch (University of Illinois at Chicago) to be presented on Wednesday 2 April (session A2.2) suggests that the crab may have evolved a rather novel solution.

For us mammals, the key to getting rid of waste ammonia is to detoxify it into urea in the liver. Marine organisms can employ the rather simpler solution of allowing the toxic ammonia to diffuse into their environment. However,
