Spaceflight Changes Human Species

Careful Spectator readers may recall this writer’s review of “Endurance,” Scott Kelly’s book about his 11 months living on the International Space Station (ISS) zipping around the Earth at 17,000 miles an hour. His journey was part of the $1.5 million NASA Twins Study when medicos compared his physiological changes with his identical twin brother, Mark Kelly, who is a retired NASA astronaut.

Cornell Alumni News magazine interviewed Weill Cornell Medical School Professor Chris Mason about preliminary results of his work on the study plus some reporters’ misinterpretations plus some funny tweets from the subjects that created headlines that space travel “had transformed an astronaut into something other than human.

But given time. Ears are a peculiarly individual piece of anatomy. Those little fleshy seashells, whether they stick out or hang low, can be instantly recognizable in family portraits.

And they aren’t just for show. The study was published in the Journal of Neuroscience, the brain adjusts to the new shape, regaining the ability to pinpoint sounds with almost the same accuracy as before.r
