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.

Personal security isn’t a concern merely for crazies grooming the sod over their backyard fallout shelters. In Orange Alert America, nasty images of what might happen are relevant, universal worries. So Popular Science challenged the Core77 online industrial-design community (core77.com) to imagine the future of personal security. What kinds of devices could protect us and our worldly possessions? We received 120 entries; in the end, these three concepts stood out because they address real fears in a practical way.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
