"We can see how drug use changes the brain," Leshner said, adding that the use of drugs "usurps the brain's motivational priorities."

... Toronto (U of T) have identified the protein that triggers the autoimmune response in Sjgren syndrome, a prevalent autoimmune disease, as well as a candidate vaccine to treat this condition. This research is reported in the October 5 issue of the scientific journal The Lancet. Using a mouse model that natura...Chemical switch determines if healthy cells are killed by chemotherapy

We found that PTEN is absolutely critical to how large our hearts become. But to find out that it also plays a major part in contr...Researchers identify enzyme that turns on RNA
...is even better. Scientists have long searched for triggers that activate ribonucleic acid (RNA), a key component in gene expression. Now, in the Thursday, Sept. 19 issue of the journal Nature, scientists from the University of Wisconsin-Madison report that they have found an enzyme that activates RNA, which ...Scientists at the Scripps Research Institute discover how a plant times its flowering cycle

CONSTANS triggers the flowering of the plant, but only when the timing is right--it must first be activated by the right number of cryptochrome and phytochrome molecules. The expression of CONSTANS also varies throughout the day. It is only expressed (in an inactivate......s on reciprocity - exploitation may not pay, if it triggers retaliation.
