Just Not Too Much http://wdiy.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.

Just Not Too Much Smallpox Virus Found In Unsecured NIH Lab http://wdiy.org/post/smallpox-virus-found-unsecured-nih-lab Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: vials labeled "variola" — in other words, smallpox.<p>Under international convention, there are supposed to be only two stashes of this deadly virus: one at the federal Centers for Disease Control and Prevention in Atlanta, and another at a similar facility in Russia.<p>The CDC swooped in to collect the vials and carted them off to a secure lab at its Atlanta headquarters.<p>In a statement Tuesday, the agency said scientists did indeed find smallp Tue, 08 Jul 2014 17:52:00 +0000 Richard Harris 43376 at http://wdiy.org Smallpox Virus Found In Unsecured NIH Lab Quick DNA Tests Crack Medical Mysteries Otherwise Missed http://wdiy.org/post/quick-dna-tests-crack-medical-mysteries-otherwise-missed Researchers are developing a radical way to diagnose infectious diseases.

Unfortunately, they came home with unwelcome hitchhikers: measles viruses.<p>Those travelers hadn't been vaccinated against this highly contagious disease, the Centers for Disease Control and Prevention said Thursday.

Over the years, there have been a number of promising cancer "cures," possible Alzheimer's treatments, and candidate drugs for holding back the ravages of various degenerative diseases.<p>But, time after time, these great promises fade away once the potential treatments are tried in people. There are lots of reasons for that.

Well, it's time to add penguins to your list of mental images.<p>Yes, <a href="http://www.penguinworld.com/types/adelie.html">Adelie penguins</a>, which breed in huge colonies on the rocky Antarctic Peninsula, also harbor a version of the avian influenza virus, according to a <a href="http://mbio.asm.org/">study published</a> in the journal, <em>mBio</em>.<p>Fret not.

Now that it's largely controlled with a vaccine, scientists have had a chance to figure out how the disease came into being in the first place.<p>That story is told in a <a href="http://mbio.asm.org/content/5/2/e01074-14.full?sid=b438c0ee-50da-448f-8c94-4f7d08dd7700">study</a> published online this week in the journal <em>mBio</em>.

The resulting egg was implanted in the womb of a third sheep, and the result was Dolly, the first clone of a mammal.<p>Dolly's birth set off a huge outpouring of ethical concern — along with hope that the same techniques, applied to human cells, could be used to treat myriad diseases.<p>But Dolly's birth also triggered years of frustration.

But the disease is so rare, there's no incentive for big pharmaceutical companies to develop a treatment.<p>Even so, some small companies, given government incentives, are stepping into that breach. The result: More than half a dozen ideas are being pursued actively.<p>And these are boon days for drugs that can treat viruses.
