New genetic mechanism for evolution
...dividuals that have chromosomes with the inversion show
some advantages over those that don't, even though it still unclear what is the mechanism used by the inversions to cause these differences. In the case of the of Drosophila buzzatii a lot of transposons were found inserted in the break points...

Impact of Earth's rising atmospheric carbon dioxide found in world oceans

that the ocean and atmosphere are the two primary 'sinks' [holding tanks] of this carbon dioxide since the beginning of the industrial revolution. The land is the 'source.'" But that ocean "sink" may be changing, the studies conclude. "Feedbacks be...

New drug shows promise against Gleevec resistance in mice
...ed and improved by structural biology studies that show
how the drugs "fit" with their target, and how mutations alter the shape of that target. The all-important drug target in chronic myeloid leukemia (CML) is an enzyme called Abelson tyrosine kinase (ABL), which becomes overactivated by a chr...
Carnegie Mellon neuroscientist develops tool to image brain function at the cellular level
...nse to sensory input. Her results are the first to show
alterations in the rate at which neurons transmit electrical signals after increased sensory input in vivo. Barth's technology is based on the decades-long understanding that a neuron must turn on new genes to firmly encode memories in the brain. Ea...
Mouse brain stem cells capable of converting into blood vessel cells
... 6 percent of the mouse neural stem cells began to show
signs that they had developed into cells similar to endothelial cells. The new cells expressed CD146, Flk-1 and VE Cadherin, protein markers that are associated with endothelial cells. They also retained a single nucleus and had only mouse chromosome...

Sleepless over Seattle: Migrating songbirds forgo sleep but keep their wits
...e authors note, "both depressed and manic patients show
reduced latency to REM sleep, loss of slow-wave sleep, and reduced amounts of total sleep." Understanding the mechanisms that power the sleepless flight of songbirds promises to unravel one of the longstanding mysteries of their improbable journey. B...

A genetic model for hereditary spastic paraplegia (HSP) disease

a progressive dysfunction that culminates in degeneration. Genetic anomalies in more than 20 different genes have been associated with HSP, but mutations in one gene in particular, SPG4, are responsible for more than 40% of all cases. SPG4 encodes a ...

...embryo. "With this research, we have been able to show
that this form of CHD can be caused by defects within the cells that line blood vessels. This research could lead to new ways to modify the growth of blood vessels because this receptor seems to tell blood vessels in which direction they should grow...
