It starts with a bioink that’s made using human skin cells.

Penn State University scientists have discovered a way to build a flow battery that converts carbon dioxide into usable energy. While this technology might not be commercially available for a long time, it could eventually help to drastically decrease carbon emissions as we move away from fossil fuels.

Researchers will use a new type of brain implant to stimulate the visual cortex in monkeys, essentially recreating the activity usually triggered by neuron signals from the eyes. Instead of using electrodes to induce electrical activity within the brain, this new type of brain implant uses magnetic fields, thus avoided degradation problems due to scar tissue.

Imagine if someone, after reading something you wrote online that they didn’t agree with, decided to forge racist and anti-Semitic emails under your name. This appears to be what happened to J. Alex Halderman, a computer security researcher and
