Fake warnings on e-cigarette ads distract kids from truth

A study by Ohio State University found that fake warnings in e-cigarette ads, similar to those recently banned by the FDA, stick with kids and desensitize them to real health warnings. The research used fake ads with 'flavor' or 'less harmful' messages and found they were more memorable than actual warnings.

Diabetes' sworn enemy could ultimately be a valuable ally

A new study suggests that glucagon can help regulate insulin action and prevent blood sugar levels from becoming too high. By activating a protein called PGC1A, glucagon can prepare the liver to respond quickly to insulin signals after meals.

Social anxiety disorder may increase risk of alcoholism
