A new device could make it much faster to convert pulses of light into electronic signals and back again. The technology could be applied to ultrafast, high-capacity communications, imaging of the Earth's surface and for encrypting secure messages.
Applications are now being accepted for Johns Hopkins Institute for NanoBioTechnology's summer 2010 International Research Experience for Students (IRES) program. Both undergraduate and graduate positions are available. Application deadline is March 19, 2010.
Microelectromechanical devices gave us the Wii and the digital projector. MIT researchers have found a way to manufacture them by stamping them on plastic, opening up the possibility of coating large areas with tiny sensors.
Nanoparticles are atmospheric materials so small that they can't be seen with the naked eye, but they can very visibly affect both weather patterns and human health all over the world - and not in a good way, according to a new study.
MIT neuroscientists have designed a new MRI sensor that responds to the neurotransmitter dopamine, an achievement that may significantly improve the specificity and resolution of future brain imaging procedures.
Another decisive step forward in the development of quantum computers has been successful. For the first time ever, researchers have accomplished to place two nitrogen atoms in a distance of only few nanometers, so that laser excitation will be capable of creating a quantum mechanical coupling.
Microorganisms are everywhere and most of them are harmless, but they can do a lot of damage in the manufacture of pharmaceuticals or in tissue transplants. With the aid of a new device, germs can be detected in artificial cartilage within a few hours.
