The introduction of abuse-deterrent OxyContin, coupled with the removal of propoxyphene from the US prescription marketplace, are getting the credit for decreasing opioid prescribing and overdoses in JAMA Internal Medicine. Those two changes led to a 19 percent drop in prescription opioid supply that was mirrored by a 20 percent drop in prescription opioid overdose between August 2010 and December 2012. The drop in prescription opioid overdose was partially offset by an increase in overdose due to heroin, an illicit opioid.

The horticulturist who came up with the concept of 'evolution by natural selection' 27 years before Charles Darwin did should be more widely acknowledged for his contribution, states a new paper by a King's College London geneticist.

Though it is widely believed that the media objectifies women, women further diminish themselves by constantly comparing their bodies to others'.

Facebook users with so-called optimistic bias think they're less likely than other users to experience cyberbullying, depression and other negative social and psychological effects from using the site, a Dartmouth-Cornell study finds.

The study suggests that optimistic bias, or an intrinsic tendency to imagine future events in a favorable light that enhances positive self-regard - in other words, wishful thinking - leaves those Facebook users vulnerable to the negative realities of social media.
