No butts about it: Teens who view smoking in movies likely to use cigarettes for the first time
ANN ARBOR, Mich.-Teens who see movie characters using cigarettes are quicker to try smoking than their peers who did not watch the same scene, a new study finds. - However, the exposure to movie images involving cigarettes does not appear to lead teens who have tried smoking to become regular smokers sooner, said Sonya Dal Cin, an assistant professor of communication studies at the University of Michigan and the study's lead author.

How bacteria fight fluoride in toothpaste and in nature
Yale researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay. - In the Dec. 22 online issue of the journal Science Express, the researchers report that sections of RNA messages called riboswitches - which control the expression of genes - detect the build-up of fluoride and activate the defenses of bacteria, including those that contribute to tooth decay.

Scientists Pioneer New Method for Watching Proteins Fold
Scientists Pioneer New Method for Watching Proteins Fold
A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins.

Lower classes quicker to show compassion in the face of suffering
Emotional differences between the rich and poor, as depicted in such Charles Dickens classics as "A Christmas Carol" and "A Tale of Two Cities," may have a scientific basis. Researchers at the University of California, Berkeley, have found that people in the lower socio-economic classes are more physiologically attuned to suffering, and quicker to express compassion than their more affluent counterparts.

Timing is key in the proper wiring of the brain, Yale researchers find
After birth, the developing brain is largely shaped by experiences in the environment. However, neurobiologists at Yale and elsewhere have also shown that for many functions the successful wiring of neural circuits depends upon spontaneous activity in the brain that arises before birth independent of external influences.
