Smells may trigger alcohol craving, and relapse, among alcoholics
Environmental stimuli like smells may induce

a neurochemical response in the brain that may "reinstate alcohol-seeking behavior" after withdrawal...

the production of more chemoattractant for the macrophages. "Once we figure out what the chemoattractant is, it might be possible to inject very small amounts of that." The studies illustrate how a clinical observation can inform basic science rese...
Researchers show that proteins can transmit heritable traits

a cell to flip from one phenotype to another." By contrast, she said, techniques of using DNA mutation to alter such phenotypes are highly specific to each protein and cannot be reversed. In the article published in the journal Molecular Cell , Li...

anxiety in mice by feeding them a drug that selectively blocked the Crhr2 receptor. Further tests, in which the researchers used drugs to turn the Crhr1 receptor on or off, ruled out the Crhr1 receptor as a cause of anxiety-producing activity. And...

UC Berkeley biologist disputes current dogma that genetic mutation is the cause of cancer

cancer in humans, but none are mutagens. "The mutation hypothesis predicts that all carcinogens are mutagenic," he said. "Yet half of all carcinogens are not mutagenic, so how do they cause cancer?" Plus, Duesberg argues, if genetic mutations cause c...
