A system being tested in rats may partially restore sight for some blind people. A handheld computer processes images from a video camera that sits on specialized goggles. Lasers inside the goggles send that information to photovoltaic chips implanted in the eye, stimulating nerve cells that send information to the brain. The person then perceives the images seen by the camera. Credit: James Loudin/Nature Photonics

Russian researchers build partial android for bizarre mind-transfer project (video)


A discovery at the University of Wisconsin-Madison may represent a significant advance in the quest to create a "hydrogen economy" that would use this abundant element to store and transfer energy.

Tiny patterns cut into this narrow copper strip filter microwaves. This new, simple technology makes it possible to take digital pictures faster, with less computer time required. And it could be used to help make airport scanners smarter, faster and cheaper. Credit: J. Hunt/Duke

Mind Blown: Real Image of T4 bacteriophage (a virus) via electron microscope.

This photo by Igor Siwanowicz shows the open trap of an aquatic carnivorous plant known as a humped bladderwort (Utricularia gibba). The plant floats in water waiting for its prey to touch its trigger hairs, which cause the plant to open its trap so quickly that it sucks in water as well as some unlucky microinvertebrates. The pretty little flakes near the bottom of the image are single-cell algae that live inside the trap. The image is magnified 100 times.
