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.
It’s called Cayla, it’s about a foot tall, and it can be used to listen to and talk to the child playing with it. But who is doing the listening? Anyone in Bluetooth range, reports Germany’s Federal Network Agency (Bundesnetzagentur). An official watchdog in Germany has told parents to destroy a talking doll called Cayla […]
The Stower Candle Charger, in addition to being a basic emergency stove, powers USB gadgets with fire: put a fuel canister under it and it’ll transmute heatrons into juicetrons as described in the Codex Ifritanimus. One canister will charge a smartphone twice; actual wax candles will presumably not stretch so far. When power outages hit, […]
The GPD Pocket is a wee laptop with a 7″ high-dpi touchscreen display and an enticing $399 price tag. It’ll be light on power, with an Intel Atom CPU, 8GB of RAM and a 128GB SSD, but promises about 12 hours on a charge and two USB ports, one of them type C. There’s a […]
Python is immensely popular in the data science world for the same reason it is in most other areas of computing—it has highly readable syntax and is suitable for anything from short scripts to massive web services. One of its most exciting, newest applications, however, is in machine learning. You can dive into this booming […]
