Indiana University, EPA to study airborne PCBs

...e semi-volatile, which means the toxins can easily alternate between liquid and gaseous states. Hites and other environmental scientists have found that some of these airborne PCBs waft toward the Great Lakes and dissolve into them. "Input from the air is one of the main ways that these chemicals can get into ...

Molecular motor myosin VI moves 'hand over hand,' researchers say

... is the hand-over-hand model in which the two arms alternate in the lead. The other model is the inchworm model in which one arm always leads." To examine the myosin VI stepping mechanism, the researchers applied the same technique that was used to study both myosin V and kinesin. Called FIONA -- Fluorescenc...

Probing the surface of white blood cells to enhance immune system medicine

...hat microvilli are dynamic structures that rapidly alternate between states of assembly and disassembly. This means that if researchers were able to biochemically dissect mechanisms by which microvilli assemble and segregate, they would be able to use this knowledge to develop immunosuppressive or anti-metast...

$6 million appropriation to focus Sandia research on drinking water desalination, removal of arsenic

...htower says. "For that reason it is important that alternate ways to power these processes be developed." The Tularosa Basin in south-central New Mexico was selected as the desalination facility location because it contains a range of brackish water - from almost fresh to twice as salty as sea water, all withi...

Male susceptibility to disease may play role in evolution of insect societies

...se they are haploid, Hymenopteran males can't have alternate forms of any genes, or in other words, individual males have no genetic variability. This, O'Donnell and Beshers contend, puts males at a higher susceptibility to disease. The researchers, who are trying to understand the basis of social behavior ...

Learned social preference in zebrafish

When subject fish were later allowed to choose which color of fish to associate with, they greatly preferred whichever color pattern they had been raised with, irrespective of their own color. This learned social preference could have enormous...

Catastrophic shift in species diversity and productivity of an ecosystem

...ppened because the ecosystem became locked into an alternate stable state in which herbivores were incapable of suppressing the now highly productive, competitively dominant plant. The study provides a cautionary tale that ecosystem management which alters predator abundances even slightly may cause dramatic a...
