Tested on fathead minnows - an organism often used to test the effects of toxicity on aquatic life - nanosilver suspended in solution proved toxic and even lethal to the minnows. When the nanosilver was allowed to settle, the solution became several times less toxic but still caused malformations in the minnows.
Scientists from the Functional Materials Group at the University of Kent's School of Physical Sciences have expanded the potential uses of glass by developing an experimental technique that reveals more clearly how atoms in glass vibrate.
Researchers from A*STAR Institute of Microelectronics (IME) join efforts to fight emerging infectious diseases with their breakthrough total analysis solution that combines sample extraction, ribonucleic acid amplification and detection into one set-up.
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.
