It was 1938, and the pain of the Great Depression was still very real. Unemployment in the US was around 20%. New machinery was transforming factories and farms, and everyone was worried about jobs.

Compton, the president of MIT from 1930 to 1948 and one of the leading scientists of the day, wrote in the December 1938 issue of this publication about the “Bogey of Technological Unemployment.”

It's a worthwhile reminder that worries over the future of jobs are not new and are best addressed by applying an understanding of economics, rather than conjuring up genies and monsters.

This high-tech mouthguard might help prevent concussions
When athletes or soldiers have a concussion, the most beneficial course of action is to simply get them off the playing field or out of the action so they can recover. Yet much about head injuries remains a mystery, including the reasons why some impacts result in concussion while others don’t.
New measuring devices, such as the Impact Monitoring Mouthguard, are being developed that could help deliver a wealth of information about head impacts. By giving an immediate warning that a person needs to be removed from action or play, they could help protect soldiers and athletes alike from brain damage. Read the full story.
