Scientists reveal the shape of a protein that helps retroviruses break into cells

...niversity of Washington scientists suggests that a sharp decline in atmospheric oxygen levels was likely a major reason for both the elevated extinction rates and the very slow recovery. Earth's land at the time was still massed in a supercontinent called Pangea, and most of the land above sea level becam...

Low oxygen likely made Great Dying worse, greatly delayed recovery

Master gene controls healing of skin in fruit flies and mammals

...d repair the body envelope that protects them from sharp edges and microbes, even though that body envelope is constructed of mostly different molecules." In their paper, the UCSD researchers state that studying the wound response pathway in fruit flies, which are easy to manipulate genetically, may provi...

Genpathway and Baylor College of Medicine Identify New Genes in Breast Cancer

... specific locations in the cortex, " said Buck. In sharp contrast to the olfactory bulb, where signals from different receptors are segregated, inputs from different odorant receptors overlap extensively in the cortex. Moreover, individual cortical neurons are likely to get inputs from many different odora...

Duke engineers develop new 3-D cardiac imaging probe

... the 504 sensors, provides great sensitivity and a sharp image, Smith said. And because the image is large enough to encompass the whole volume of the heart, fewer "pictures" need to be taken. This may shorten patient time in clinics, he said. ...

Great White shark evolution debate involves WSU Lake Campus geology professor

...ities between the Great White and megladon exhibit sharp differences. In summary, our morphological (form and structure) evidence strongly supports the theory that the Great White is descended from the prehistoric mako group." Ciampaglio said the Great White sharks, which can reach a size of nearly 25 fee...

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

...as amyloid fibrils. Atomic force microscopes use a sharp microscopic tip to image surfaces and detect energy differences by mechanically probing molecular surfaces. In a poster presentation at the American Chemical Society's annual meeting, the researchers will describe the first biophysical analysis of i...
