A new study by researchers from the University of Waterloo in Ontario, Canada, hints that carbon nanotubes may be toxic to microorganisms. When cultures of a certain key protozoan, a single-cell organism, ... | |
Developing better nano-electronics by understanding nonadiabatic effects June 17, 2008 | User rating: 4.3 / 5 after 25 vote(s)
| User comments: 2
“Basically,” Michele Lazzeri tells PhysOrg.com, “the Born-Oppenheimer adiabatic approximation tells us how atoms are vibrating.” This adiabatic effect is used to describe phonons, which are modes of vibration that ... | |
 World's Largest Quantum Bell Test Spans Three Swiss Towns June 16, 2008 | User rating: 4.6 / 5 after 122 vote(s)

It wasn't too long ago in human history that people rarely, if ever, traveled beyond the village they were born in. We've come a long way since then: according to the World Tourism Organization (WTO), international ... | |
 Liquid Crystals Slow Light Pulses to a Snail's Pace June 10, 2008 | User rating: 4.6 / 5 after 99 vote(s)
| User comments: 13
In a vacuum, the speed of a light pulse is always a constant at 186,000 miles (300,000 km) per second. But by changing the medium through which light travels, physicists can slow down light pulses, and possibly ... | |
