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.
The LG Watch Urbane 2nd Edition LTE was the company’s latest answer to Apple’s dominating entry into the market. But it died fast, pulled off the shelves within a week due to an unspecified problem with the display. Ron Amadeo writes that they “are not in a position to communicate the specifics of the issue […]
I’ve been using Stanley’s classic flask for years (I literally packed one, full of nice bourbon, in my suitcase this morning for the Melbourne/Sydney/Berlin trip I’m leaving on tonight), and I have no complaints: it’s beautiful, easy to close, and rugged.
Mattel’s Hello Barbie has a microphone and a wifi interface, and it transmits the phrases it hears to a central server in order to parse them and formulate a response. Mattel claims that the data isn’t being retained or harvested for marketing purposes, and assures parents that they can make Barbie stopping eavesdropping on them […]

Store more on your Mac with this microSD memory card adapter.
Carrying this EDC card is like slinging around a handheld toolbox wherever you go. Its minimal design is small enough to fit in your wallet’s billfold, and it’s TSA-compliant so you’ll never leave it behind. It’s got hex wrenches, metric and imperial rulers, flathead and Phillip’s screwdrivers, and a bottle opener so that you’re ready […]
