Those officials now recognize a <a href="http://www.npr.org/2014/07/09/330038131/researchers-aghast-over-discovery-of-smallpox-vials">pattern of problems</a> in their world-class laboratory.

Just Not Too Much http://www.kunc.org/post/all-animals-we-need-stress-just-not-too-much Ask somebody about stress, and you're likely to hear an outpouring about all the bad things that cause it — and the bad things that result. But if you ask a biologist, you'll hear that stress can be good.<p>In fact, it's essential.<p>For example, the adrenal glands of all animals have evolved to pump out <a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3079864/">stress hormones</a> in unexpected situations — the hormones spur action and increase fuel to the brain, helping the animal react to danger appropriately.
