Discovery: Scientists find new reason red blood cells cut blood flow in sickle cell disease victims
...molecular signals that make those cells stick more readily to blood vessel walls. The protein works by activating a receptor on the surface of red cells called integrin-associated protein, or IAP, said Parise, a member of both UNC's Center for Thrombosis and Hemostasis and Lineberger Comprehensive Canc...UNC, Penn State scientists find gene that controls water retention in plants
... the gene nonfunctional. Mutant plants wilted more readily than normal plants because they were unable to retain water as well. The UNC scientists suspected that the gene they targeted encodes a critically important molecule called a G protein that plays a central role in regulating the various signals such...Gene therapy restores feeding behavior to starving mice
...amen also rejuvenated nest-building behavior. Mice readily build nests when given nesting material, said Palmiter. But in the absence of dopamine, the mice never built nests. Since the treated mice resumed nest-building, we suspect that other motivated behaviors may also be rescued by treatment.

The bacteria are able to switch from a metabolism based on organic carbon to one based on photosynthesis, depending on the concentration of organic matter in ocean water, says the researcher. ...New system developed for removing contaminants from storm run-off

"About half [the species] we saw came in fast," said Galatowitsch.

Histone H3 in active DNA had a methyl group attached to a different, nearby lysine amino acid, ......es called lignins, which contain carbon but do not readily decompose. After the plant dies, some of its carbon remains locked up in the lignins and can become buried in the Earth through geologic processes, preventing those carbon atoms from returning to the atmosphere and effectively lowering atmospheric c...UCSF study finds two old drugs may help fight prion diseases
...h, because it crosses the blood-brain barrier more readily and therefore could provide a higher dose of the drug in the brain. The mouse cells used in the study were neuroblastoma cells, cancer cells that, by definition, multiply perpetually. These cells have been the basis of some prion studies for more th......e ASMs make the drugs water-soluble so they can be readily transported through the skin, eyes, intestinal walls or any other body tissue. Most drugs are hydrophobic and thus not easily soluble in the bloodstream, Uhrich explained.
