Science Round-up


  • Hey, look, Voyager I is preparing to leave (or has left) the solar system for the 3,123rd day straight.  

    I’m just sad that I won’t be here 200 or so years in the future when it comes back.

Neuroscientists have found that sleep deprivation amplifies anticipatory anxiety by firing up the brain’s amygdala and insular cortex, regions associated with emotional processing. The resulting pattern mimics the abnormal neural activity seen in anxiety disorders. Furthermore, their research suggests that innate worriers — those who are naturally more anxious and therefore more likely to develop a full-blown anxiety disorder — are acutely vulnerable to the impact of insufficient sleep.

So apparently, I need to go to bed earlier.

  • This seems like a humane and smart solution.

In another step toward ending biomedical research on chimpanzees, the National Institutes of Health announced on Wednesday that it would begin the process of retiring most of its chimps to sanctuaries, though it will leave some for possible future research.

The decision, which follows the recommendations of an agency advisory group, does not end biomedical research on N.I.H. chimpanzees. But it calls for retiring about 310 animals that the agency owns over the next few years, to sanctuaries from which they cannot be recalled for research. A colony of up to 50 will be kept at a site yet to be decided in case there is a compelling need to use them in research for human health. And new guidelines will be in place for any future research and for chimpanzee housing.
