Nanotechnology might soon save you a trip to the dentist. Researchers have developed tiny sphere-shaped particles that ferry a payload of bacteria-slaying drugs to the surface of the teeth, where they fight plaque and tooth decay on the spot.
A new study demonstrates for the first time how elemental carbon became an important construction material of some forms of ocean life after one of the greatest mass extinctions in the history of Earth more than 252 million years ago.
Consider, for a moment, the chair your butt is resting on right now (or the floor, if you’re standing). It’s made of a squillion atoms right? And it’s all those tightly packed atoms/marbles that are holding your butt in the chair against the force of gravity, right? Well, actually, no.

Rochester’s Washington D.C. delegation is again throwing its political weight behind New York landing a federally created center for photonics manufacturing. The White House last year announced that through the U.S. Defense Department it would put $110 million toward creation of a high-tech Institute for Manufacturing Innovation with a focus on photonics.
Developed by a team at the University of Rochester’s Human-Computer Interaction Group, the system is called Rhema, and it works by recording a speaker, analyzing the volume and rate of the recorded words, and immediately displaying recommendations for changes.
