Physicist cracks women's random but always lucky choice of X chromosome

... into a single protein plug. That single plug then closes off one of the XIST suicide genes allowing its host X chromosome to continue to operate. However the other XIST suicide gene is now freed to activate and shuts down its X chromosome. Since putting forward this explanation researchers in Harvard ha...

Brain networks strengthened by closing ion channels

...ctively disconnected. Arnsten said inhibiting cAMP closes the channels and allows the network to reconnect. The study also found alpha-2A adrenergic receptors near the channels that inhibit the production of cAMP and allow the information to pass through into the cell, connecting the network. These recep...

UCSD study reveals how plants respond to elevated carbon dioxide

...ave an advantage for the plant. "Even if a plant closes its pores a little in response to increasing atmospheric carbon dioxide, it would still have access to carbon dioxide," said Schroeder. "On the other hand, less water would be escaping through the pores, so the response might help plants use water mo...

Novel connection found between biological clock and cancer

...ck regulates expression of the period-4 gene. This closes a loop connecting the clock to period-4 and period-4 to the clock and the cell cycle. The clock normally modulates expression of this gene that encodes an important cell cycle regulator, and that cell cycle regulator in turn affects not only the cell...

MIT chemist discovers secret behind nature's medicines

... After the iron and the chloride bind, the protein closes down around the active site, effectively pulling the trigger on the gun. "We were surprised," Drennan said. "The change in activity required for an enzyme to be capable of catalyzing a halogenation reaction is so radical that people thought there mu...

Telling axons where to go - and grow

...ng that Rnf6 targets LIMK1 for degradation finally closes this circle of regulation, providing the link between actin dynamics, axonal growth and Rnf6. Importantly, the authors are able to show that changes in axon outgrowth induced by changes in levels of Rnf6 can be restored by compensatory changes in LI...

Membrane research opens window to benefits for plants, humans

...ter-protein channel -- an aquaporin that opens and closes a gate that regulates water movement in and out of cells. Not only was the discovery the first for a plant-water channel, it was the first plant-membrane channel for which an atomic resolution structure has been determined. "By recovering an X-ray s...

Female butterflies go for sparkle -- not size -- when choosing to mate

..."When the male approaches the female, he opens and closes his wings in rapid succession so she can observe his pupils," she explained. "We believe the purpose of the fluttering of his wings is two-fold: to spread pheromones to her antennae and to stimulate her visually. The female appears to be very sensiti...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers
