Bacteria growing on your hard drive right now? That's bad — very bad. But in the future, it could be the basis on which your hard drive — or even your entire computer — is built. The BBC reports on research undertaken jointly in the UK and Japan that uses iron-eating microbes called Magnetospirilllum magneticum. No particular prizes for guessing what makes these little fellas interesting; as they ingest the iron it becomes magnetic, forming tiny particles. In nature, the Magnetospirilllum magneticum align along the Earth's magnetic field lines — or in other words, forming arrays. The researchers used this natural behaviour to build specific magnets, and it's hoped the research could be fine-tuned into building storage devices; they've already had some success in using microbes to build nano-wires.

Ever since the seven-or-so-year time jump earlier this season, viewers of the venerable zombie series have wondered what the hell happened between Rick’s departure and the present that led to the breakdown between the various communities and turned Michonne from someone trying to honour Carl’s vision of hope into a hardass willing to let anyone suffer as long as her own people are safe.

If you thought ray tracing was only going to be possible on Nvidia’s pricy line of Turing GPUs you would be wrong.

The 1060 can notably be found for as little as $259 and its price is expected to drop even further.
