ASU researchers demonstrate new technique that improves the power of atomic force micrscopy
...al microscopes optical sensitivity for much larger objects (~1 micron)." Atomic force microscopes provide images on the nanometer scale by using a highly sensitive and tiny probe that is essentially pulled across a surface. By doing this, researchers can obtain topographical images down to a nanometer scale....New understanding of the machinery of flinching
...his case those that represent a sudden approach of objects to the body. "PZ may provide an example in the motor system of a relative hotspot for the ethologically important function of defense of the body surface, although PZ may of course have other sensory and motor functions not tested in the present expe...Penn scientists identify novel pathway in aneurysms
...yer, as expected. (Macrophages engulf such foreign objects as cellular debris, excess fats, and dying cells.) When the researchers inactivated the gene in a mouse model of arteriosclerosis, the number and degree of severity of aneurysms in the mice was markedly reduced. "In humans it has been very difficult ...Rare deficit maps thinking circuitry

The researchers report on the..." circuit processes information about locations of objects and spatial relationships, whereas a parallel "what" circuit, running downward from the back of the ...A genetic disorder yields insight into genes and cognition
...--a ventral pathway that processes the identity of objects and a dorsal pathway that processes spatial information on them. Thus, reasoned the researchers, the weakness in "visuospatial construction" in people with WS likely lies in the dorsal pathway. In their experiments, the researchers performed function...AACR applauds NCI initiative on nanotechnology
...he most elemental level of biology. Such nanoscale objects can be useful by themselves or as part of larger devices containing multiple nanoscale objects. The new effort is designed to enhance cross-disciplinary and cross-sector collaborations in nanotechnology, which scientists now believe is poised for pri...... In Isaac Newton's theoretical universe, colliding objects retain their shape, like two billiard balls. In the real world, things don't always happen so neatly. Superfast bullets crumple on impact, and ceramic-based body armor dents or shatters in a variety of ways. Computing the forces involved is so comple...
