KONARKA AND EVIDENT TO DEVELOP ULTRA HIGH PERFORMANCE POWER PLASTIC, March 23
Companies' novel polymers and quantum dots target capturing broad spectrum of both visible and invisible light

Konarka Technologies, Inc., an innovator in developing and commercializing power plastics that convert light to energy, and Evident Technologies, a leader in quantum dot development and applications, today announced the companies are collaborating on research to increase the sensitivity of plastic solar cells to a wider range of the light spectrum. Using Konarka's proprietary polymers and Evident's quantum dots, the team is developing novel materials that improve the overall performance of power plastic.

MEMBRANELESS FUEL CELL IS TINY, VERSATILE, March 23
A fuel cell designed by researchers at the University of Illinois at Urbana-Champaign can operate without a solid membrane separating fuel and oxidant, and functions with alkaline chemistry in addition to the more common acidic chemistry.
Like a battery, a fuel cell changes chemical energy into electrical energy. While most fuel cells employ a physical barrier to separate the fuel and oxidant, the microfluidic fuel cell developed at Illinois utilizes multi-stream laminar flow to accomplish the same task.

UCLA RESEARCHERS FIRST TO CAPTURE ELUSIVE LIGHTNING-QUICK WAVEFORMS, March 23
Discovery could help scientists develop defenses against high-powered e-bombs and allow physicists to view fundamental building blocks of nature

Researchers at UCLA have for the first time been able to capture and digitize electrical signals at the rate of 1 trillion times per second, a discovery that eventually may help scientists develop defenses against high-powered microwave weapons attacks and allow physicists to peer into the fundamental building blocks of nature.

SPINTRONIC MATERIALS SHOW THEIR FIRST MOVE, March 23
How much energy does it take for an electron to hop from atom to atom, and how do the magnetic properties of the material influence the rate or ease of hopping? Answers to those questions could help explain why some materials, like those used in a computer hard drive, become conductors only in a magnetic field while they are very strong insulators otherwise. They might also help scientists learn how to use the electron's "spin", as well as its charge, to carry information in a new field known as spintronics.

CLIMATE CHANGE POORLY UNDERSTOOD BY US PUBLIC, SURVEY FINDS, March 23
Climate change and the threat of global warming are poorly understood by the U.S. public, and taking action to reduce their impact is not a high priority, according to a recent MIT survey.
These results suggest that change in U.S. climate policy will not be led by public opinion. Elected officials will have to provide leadership--a task they will find difficult because achieving significant reduction of the greenhouse gases linked to climate change may involve economic costs well above what the average consumer is willing to pay.
