September 24, 2012 - There's promising research on a new drug to help curb nicotine cravings. An experimental drug has been shown to reduce nicotine cravings in addicted rats and baboons. Researchers say it could lead to new medicines to help people stop smoking for good. It's ready for testing in early stage clinical trials in humans. Researchers say the animal tests suggest the drug blocks dopamine receptors and helps reduce cravings. It's the first time study authors say this class of drugs has seen signs of possibly working in humans.
Also, researchers believe there may be a connection between childhood obesity and BPA. The chemical compound is used in many plastic containers and metal cans. Most people have traces of the chemical in their bodies, but a new study in the Journal of the American Medical Association found children with the highest levels of BPA in their system were twice as likely to be obese. Scientists point out that the research only shows an association and does not prove BPA causes obesity.
