Researchers think pink to produce 'green' solar energy
07-30-2007 · EurekAlert!When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light.

- New Developments in "Artificial Photosynthesis"
03-27-2007 · Brookhaven National Laboratory
Scientists at Brookhaven are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a bio-inspired system that can produce fuels like methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy.

The goal is to design a system that can produce methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy. Four Brookhaven chemists will discuss their research on this "artificial photosynthesis" at the 233rd National Meeting of the American Chemical Society.

- Color names: More universal than you might think
10-18-2006 · EurekAlert!
From Abidji to English to Zapoteco, the perception and naming of color is remarkably consistent in the world's languages. Across cultures, people tend to classify hundreds of different chromatic colors into eight distinct categories: red, green, yellow-or-orange, blue, purple, brown, pink and grue (green-or-blue), say researchers in this week's online early edition of the Proceedings of the National Academy of Sciences.

- Bacteria that use radiated water as food
10-19-2006 · EurekAlert!
Researchers from Indiana University-Bloomington and eight collaborating institutions report in this week's Science a self-sustaining community of bacteria that live in rocks 2.8 kilometers below Earth's surface. Think that's weird? The bacteria rely on radioactive uranium to convert water molecules to useable energy.

- Shedding new light on proteorhodopsin
02-09-2007 · EurekAlert!
New light has been shed on proteorhodopsin, the light-sensitive protein found in many marine bacteria. Researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have demonstrated that when the ability to respire oxygen is impaired, bacterium equipped with proteorhodopsin will switch to solar power to carry out vital life processes.

- Argonne researcher studies what makes quantum dots blink
10-04-2007 · EurekAlert!
In order to learn more about the origins of quantum dot blinking, researchers from the US Department of Energy's Argonne National Laboratory, the University of Chicago and the California Institute of Technology have developed a method to characterize it on faster time scales than have previously been accessed.

- Nanowire generates power by harvesting energy from the environment
09-27-2007 · EurekAlert!
As the sizes of sensor networks and mobile devices shrink toward the microscale, and even nanoscale, there is a growing need for suitable power sources. Because even the tiniest battery is too big to be used in nanoscale devices, scientists are exploring nanosize systems that can salvage energy from the environment. Researchers at the University of Illinois have now shown that a single nanowire can produce power by harvesting mechanical energy.

- Something new under the Sun
01-30-2007 · EurekAlert!
That plants grow better if grown in a greenhouse in the correct climate is nothing new. Dutch researcher Rachel van Ooteghem has designed a control system for an improved solar greenhouse that yields more. In the new greenhouse, good climate control with sustainable energy resulted not only in an increased crop yield but also a lower gas bill.

- ASU researcher finds belief about neighbor's conservation is stealthily influential
02-18-2007 · EurekAlert!
If everyone jumped off a bridge, would you? Probably not, but according to a study by Arizona State University researchers, peer influence plays a greater role in people's behavior than is generally acknowledged. The study, which is being presented by ASU Regents' Professor of Psychology Robert Cialdini on Feb. 18 at the annual meeting of the American Association for the Advancement of Science, suggests that peer influence is an under-recognized factor in energy conservation.
