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.
Sony’s cameras seem to be in a league of their own. So why do professionals stick with bulkier models from Canon and Nikon? One answer is glass—often just as pricey as pro-grade bodies, and you need a lot of it to be in business. DPReview’s Dan Bracaglia suggests that Sony’s latest full-frame model, the $5,000 […]
Chester (or Shasta?), a Red Labrador, has figured out a way to deal with the Roomba that’s more efficient than barking at it or biting it: turning it off. [Thanks, Heather!]
An EU court ruled against a seller of customized set-top boxes this week, with the judge saying that his preinstallation of certain Kodi Add-Ons makes the boxes illegal to offer. Mr Wullems sells, over the internet, various models of a multimedia player under the name ‘filmspeler’. That device acts as a medium between a source […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
