Making nanotubes respond to rainbows Taking their cue from the eye, researchers have constructed a carbon nanotube that responds to all the colors of the rainbow. With some changes and more work, they could even have a nanometer-size photovoltaic device. The eye detects light through a photon-induced isomerization of a molecule. In its work, the group from Sandia National Laboratories attached azobenzene chromophores to a...

To the moon and back, many times a minute The moon is spiraling away at 3.8 cm, or about an inch and a half, a year. But don’t worry. Given that it sits at a distance of about 385,000 km, or just under 240,000 miles, there will be no...
Unscrambling holograms gains high-res images There’s a catch-22 to cameras. Either they have high resolution and a narrow field of view, or they have a wide field of view at a loss of resolution. One reason why resolution is poor is that...
Special effects captured in a whole new light Imagine an imaging system that doesn’t require a camera or reflective markers but instead uses small photosensors and solid-state projectors that transmit near-infrared light to capture movement. The...
