Science Today, Episode 23

It's a scene straight out of Star Wars! A prosthetic arm that can feel hot and cold, just like Luke Skywalker's. But this time, it's not just part of a movie. Also this month, Dr. Kopecky brings us news from the worldwide science journals about how different people differently perceive musical harmonies and instruments, a powerful new telescope that's spotted a brand new neutron star, and some incredible engineering bringing us breakthroughs in the science of nuclear fusion. Plus, why is syphilis making an unwanted comeback? All that and more in this month's Science Today.
