...day help them probe the basic nature of matter and build the next generation of atomic clocks and lasers. The gas consists of atoms that fall into the category of fermions, one of nature's two types of elementary particles, which by definition are antisocial particles that refuse to occupy the same energy ...Large air pollution center established at NYU School of Medicine
...he $8 million federal grant to NYU will be used to build on a body of research showing how the inhalation of fine and ultrafine airborne particles into the deepest recesses of the lungs can contribute a variety of illnesses, especially in people with pre-existing heart and lung disease. "There are ...Injured spinal neurons reach out to each other, but not to healthy neighbors
... The scientists also examined the proteins used to build these bridges, called connexins. They found that the amount and types of connexin proteins present in the neurons did not change after nerve injury. This suggests that gap junction bridges may be present among normal motor neurons but are perhaps i...National prize in neuroscience endowed by UNC professor

"What we think happens is that in response to a growth signal, MAP kinase attaches a phosphorous molecule to CPS II, thus preventing feedback inhibition and allowing cell......ass of milk on a full stomach -- can help the body build up a tolerance for lactose products.
