...substrate wettability. Thus, a water filament in a narrow channel that has a width of 100 nanometer can sustain an overpressure up to 15 atm. In contrast, if the channel had a width of one millimeter, the water filament could only sustain a thousandth part of an atmosphere. One relatively simple application...When cobras spit, there's not a dry eye in the house
... components which are harmful to tissue. Through a narrow channel in their fangs the snakes can spray the liquid at high pressure similar to a bullet in the barrel of a gun. If they manage to hit an eye, the sensitive cornea reacts with severe stinging pain. In the worst case these burns can ultimately lea...International HapMap consortium expands mapping effort

The effort to expand the HapMap is made possible by $3.3 million in additional support from a unique public-private partnership, including the following organizations: the Wellcome Trust, London, $62...Gene with broad role also causes prevalent, inherited nerve disorder
...three different chromosomal locations. To further narrow the search for causes, the Duke team screened three unrelated families, with intermediate CMT linked to one of those chromosomal regions, for defects in candidate disease genes. Family members who had the condition all exhibited unique mutations in t...B-15A iceberg's close encounter monitored by Envisat

Additional testing identified a group of chemically related compounds, one of which was TTP-6171, that appear to block replication of orthopoxviruses by inhibiting I7L without being toxic to human ce......rd during running. The tall human body with a narrow trunk, waist and pelvis creates more skin surface for our size, permitting greater cooling during running.
