Health Research: .How to eliminate pain tied to tooth decay ♦ 3-D mapping a new drug-delivery too ♦ Gene mutation linked to reckless drunken behavior

Gene mutation linked to reckless drunken behavior Researchers of the University of Helsinki, Finland, have identified a genetic mutation which renders carriers susceptible to particularly impulsive and reckless behavior when drunk

.How to eliminate pain tied to tooth decay An abundance of sweets during the holidays increases the threat of cavities and tooth sensitivity. Researchers have found a way to regrow enamel to protect teeth. Perhaps one day their gel could be used as teeth strips or in a mouth guard.
