University of Missouri engineers are building a nuclear battery the size of a penny. Their aim is to develop a long-lasting power source for tiny sensors, actuators, and labs-on-a-chip. While nuclear batteries sound, er, problematic, they're actually relatively common in larger form factors to power pacemakers and instruments aboard space vehicles. From MU News Bureau:
(Professor Jae Kown's) innovation is not only in the battery’s size, but also in its semiconductor. Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor,” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”
In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair.

Lex is a “wearable” chair, an apparatus that attaches to your thighs and waist.
First it was vinyl, then it was cassette tapes — now the latest old media that’s being praised for offering warmer, richer, higher-quality experiences?
If you’ve worked in any high-performing engineering lab, you already know about MATLAB. This computing environment and the language that powers it is perfectly suited to science and math, with an interface that makes it easy to express and visualize complex algorithms – not to mention an infrastructure that lets it easily work with other […]
Studies have shown cannabidiol (more popularly known as CBD) to be effective in two main areas: Pain relief and stress relief. Both of those make the non-psychoactive, cannabis-derived compound a natural for topical creams. There’s no shortage of CBD products out there, but here’s eight of our favorites, all specifically designed for dermatological use – […]
If you’re part of the maker community, you know Make:. Though Make: magazine is off the shelves as of this year, the eBooks and resources put out by Maker Media are still a fantastic resource for the new generation of tinkerers, hackers, and robotics geeks. If you’re in that tribe, listen up: they’ve released a […]
