The Device Scientists at Lawrence Berkeley National Laboratory have been responsible for  many discoveries over the years, but this February they published a piece that I found particularly fascinating. Seung-Wuk Lee and his coworkers have created a device that uses a single layer of viruses to generate enough electric current to run small, simple devices (like screens or sensors.) This breakthrough is exciting not only because of the device itself, but also because of its implications for the cost and environmental impact of future generations of widely adopted technologies.
