Nanoparticles Speed Light

Scientists at the University of Pennsylvania have theorized a way to increase the speed of pulses of light that bound across chains of tiny metal particles to well past the speed of light by altering the particle shape. Under the theory, nanosized metal chains would serve as building blocks for high-frequency...

Telltale Fish Embryos

Purdue University researchers have harnessed the sensitivity of days-old fish embryos to create a fiber optic-based tool to detect a range of harmful chemicals. By measuring rates of oxygen use in developing fish, the technology could reveal the presence of minute levels of toxic substances. It could thus warn of...

Asphalt Solar Collector

A research team at Worcester Polytechnic Institute is developing a solar collector that could turn roads and parking lots into sources of electricity and hot water. Roads and parking lots are typically resurfaced every 10 to 12 years, so the massive acreage of already installed roads and lots could be retrofitted at that...

GreenLight Project

The information technology industry consumes as much energy and has roughly the same carbon footprint as the airline industry. Energy usage per compute server rack is growing from about 2 kilowatts (KW) per rack in 2000, to an estimated 30 KW per rack in 2010. Every dollar spent on power for IT equipment requires that another...

Embedded Telescope

Tiny telescopes have long been mounted on glasses to help visually impaired people perform tasks, such as driving. But many potential users have resisted using them due to their appearance, whereby the lens is mounted atop the regular lens or above the frame. Moreover, the magnified view through the telescope is...
