International Panel Makes Recommendations for Achieving Sustainable Food Security – “The Commission emphasises that food security is a problem for everyone, with rich and poor countries facing different but equally challenging problems. Its recommendations support climate-resilient agricultural production, efficient resource use, low-waste supply chains, adequate nutrition and healthy eating choices that, together, will constitute a sustainable food system.” A summary of the panel’s findings can be downloaded for free here, including a sobering projection of the effect of climate change on global agricultural production for the next 50 years.

Suicidal Behavior and Depression in Smoking Cessation Treatments – 90% of reported cases of suicidal and self-injurious behavior in the FDA’s Adverse Event Reporting System (AERS) database from 1998 through Sept 2010 involve use of an anti-smoking drug sold under the brand Chantix. These results have been reported previously, but should the FDA impose stricter limits on when Chantix should be prescribed? (via PLoS One, by Singh, et. al.)
Nicotine as a Gateway Drug – It’s long been known that the vast majority of cocaine users smoked tobacco before they began using cocaine. Whether there was a link (biological, sociological, or otherwise) between tobacco and cocaine use, however, was unclear. Now new mouse studies have shown that nicotine use prior to cocaine use has a significant effect on cocaine’s effects and markers of cocaine addiction. If nicotine works the same in people, smoking cessation policies may reduce addiction to cocaine as well as tobacco. (via NIH Research Matters)
