Even if the ultra-feminine aesthetic isn’t your thing — and it’s not really mine — you have to hand it to the Barbie flip phone. From the box it comes in, to the interchangeable back plates, rhinestone stickers, and Barbie-fied interface, it’s a delight. The charger and battery are both pink, though they’re a lighter shade than Mattel’s trademarked Barbie Pink (Pantone 219). The phone says “Hi Barbie!” when you turn it on. It’s the definition of committing to the bit.

The breezy fun of the Barbie aesthetic, Pantone 219 or otherwise, is at odds with the actual experience of using the phone. It’s based on one of HMD’s feature phones, and it runs an operating system called KaiOS. The phone is designed for basic connectivity — texting, calling, emails — and even includes a web browser.

The world's first nuclear-powered battery, which uses a radioactive isotope embedded in a diamond, could power small devices for thousands of years, scientists say.

The nuclear battery uses the reaction of a diamond placed close to a radioactive source to spontaneously produce electricity, scientists at the University of Bristol in the U.K. explained in a Dec. 4 statement. No motion — neither linear nor rotational — is required. That means no energy is needed to move a magnet through a coil or to turn an armature within a magnetic field to produce electric current, as is required in conventional power sources.

The diamond battery harvests fast-moving electrons excited by radiation, similar to how solar power uses photovoltaic cells to convert photons into electricity, the scientists said.
