...s the faucet shut. But when conditions are bad, it opens the faucet so that the growth-inhibiting carotenoid byproduct flows freely from the roots, telling leaves to stop growing. Sieburth says the study didn't demonstrate what those conditions might be, but lack of water and compacted soil are likely be...UNC scientists identify sticky protein in sickle cell red blood cells
... to thrombospondin. "This knowledge opens the door to possible therapies. Inhibitors of the class of proteins to which Alpha-4Beta-1 belongs, the integrins, are being tested for use in diseases such as Crohn's disease, and these inhibitors are now attractive and rational therapies for sickle...Channel protein converts vibrations to electrical signal
...y the brain. The protein forms an ion channel that opens in response to sound, causing electrical impulses that communicate the pitch, volume, and duration of a sound to the brain. Scientists have long suspected that such a molecule must exist in the tiny cilia extending from receptor cells in the inner e...Excess dietary fat accelerates breast cancer by altering the activity of a group of genes
