Mom & Pop gold miners threaten new wave of mercury pollution
Could tons of neurotoxic mercury now stored in the United States wind up in the hands of poverty-stricken gold miners in developing countries and eventually be released into the environment, where it could end up entering the human food chain" An article scheduled for the May 28 issue of Chemical & Engineering News, ACS' weekly newsmagazine, explores that possibility in a script that reads like an environmental version of the hit film, Blood Diamond. more
Carb, protein supplements may not improve exercise performance but can reduce muscle damage
A new study in The Journal of Strength and Conditioning Research suggests that drinking a carbohydrate and protein supplement prior to and during exercise does not improve exercise performance.
