IBM researchers have built the first integrated circuit based on graphene,  a breakthrough the company says could herald a future based on graphene  wafers instead of silicon. The circuit, a 10 gigahertz frequency mixer,  could give wireless devices greater range. At higher frequencies, the  technology could someday allow law enforcement and medical personnel to  see inside objects or people without the harmful effects of X-rays,  according to IBM.


After celebrating the 67th anniversary of  D-Day this week, it's only fitting that we publish a gallery documenting  World War II-era PopSci. A warning, though: this was the 1940s, so  practically nothing in here conforms to our modern-day notion of  political correctness. Some of these headlines may sound a little  extreme, but rest assured, we took care to elaborate on the idea from a  scientific standpoint.
