In an effort to clamp down on counterfeit food, a research group in Italy has devised a chemical test to help determine the authenticity of Parmigiano-Reggiano cheese. This is according to a report published in the Journal of Agricultural and Food Chemistry.

With the nation's exploding opioid epidemic, Eugene Monroe's quest to steer NFL players away from widespread use of painkillers and possible opioid addiction continues to receive attention.

Conversely, the veteran left tackle for the Baltimore Ravens, who claims not to smoke, has willingly become a marijuana missionary, to help his NFL brethren ravaged by injuries steer clear of addiction to -- and premature death from -- painkillers.

World population growth is a hot-button issue. A large segment of the public seems to believe that humans will continue to reproduce until we run out of food and water. Basically, we're just like cockroaches or bacteria. No serious demographer believes that -- as world fertility has been declining for years -- but facts haven't killed off this pernicious myth.
