Looking To Geology To Find Answers Of How Life On Earth Originated
2014-03-13 10:20:59

[ Watch the Video: The Origins of Life on Earth ] Brett Smith for redOrbit.com - Your Universe Online By simulating a geologic precursor of cell metabolism, a team of British and American scientists have taken an important step toward understanding how life arose on Earth. Their work is published in a new paper in the journal Astrobiology. “What we are trying to do is to bridge the gap between the geological processes of the early Earth and the emergence of biological life on this...

Researchers Identify Key Intermediate Steps In Artificial Photosynthesis Reaction
2014-03-04 11:03:17

Lynn Yarris, Berkeley Lab Artificial photosynthesis, in which we emulate the process used by nature to capture energy from the sun and convert it into electrochemical energy, is expected to be a major asset in any sustainable energy portfolio for the future. Artificial photosynthesis offers the promise of producing liquid fuels that are renewable and can be used without exacerbating global climate change. A key to realizing commercial-scale artificial photosynthesis technology is the...

Photoreactions are driven by light energy and are vital to the synthesis of many natural substances. Since many of these substances are also useful as active medical agents, chemists try to produce them synthetically. But in most cases only one of the possible products has the right spatial structure to make it effective. Researchers at the Technische Universitaet Muenchen (TUM) have now developed a methodology for one of these photoreactions that allows them to produce only the specific...

Better Understanding Of Hardy Bacteria Enhances Tool For Biofuel Creation
2013-11-25 09:16:25

DOE/Pacific Northwest National Laboratory Scientists have charted a significant signaling network in a tiny organism that's big in the world of biofuels research. The findings about how a remarkably fast-growing organism conducts its metabolic business bolster scientists' ability to create biofuels using the hardy microbe Synechococcus, which turns sunlight into useful energy. The team at the Department of Energy's Pacific Northwest National Laboratory glimpsed key chemical events,...

White Wine Additive Curbs That Funky Taste
2013-11-22 04:15:32

April Flowers for redOrbit.com - Your Universe Online Food scientists report that they have found an additive which may help curb a chemical reaction that causes wine to look, smell and taste "funky." Gal Kreitman, a doctoral candidate in food science at Penn State, led the research team that added chelation compounds that bind with metals to inhibit oxidation - oxygen's ability to react with some of the trace metals that are found in wine. The results of their study were published in a...

Most of us wouldn't consider bacteria a promising energy source of the future. That would be shortsighted, says Leonard Tender, a microbial-electrochemist at the Naval Research Laboratory in Washington, D.C., who believes that the focus of his research – electrode reactions catalyzed by microorganisms – may one day provide cheap, clean and abundant energy by converting the carbon dioxide in seawater to fuel and the organic matter in wastewater into electrical power. Tender will discuss...

Oxygen ‘Sponge’ Presents Path To Better Catalysts, Energy Materials
2013-08-29 08:06:10

Oak Ridge National Laboratory Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a new oxygen “sponge” that can easily absorb or shed oxygen atoms at low temperatures. Materials with these novel characteristics would be useful in devices such as rechargeable batteries, sensors, gas converters and fuel cells. Materials containing atoms that can switch back and forth between multiple oxidation states are technologically important but very rare in...

Researchers report discovery in Science about manganese in aquatic environments An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study led by University of Delaware researchers that was published this week in "Science." The discovery alters understanding of the chemistry that moves manganese and other elements, like oxygen and carbon, through the natural world. Manganese...

In the world, there are a lot of small molecules people would like to get rid of, or at least convert to something useful, according to University of Wisconsin-Madison chemist Robert J. Hamers. Think carbon dioxide, the greenhouse gas most responsible for far-reaching effects on global climate. Nitrogen is another ubiquitous small-molecule gas that can be transformed into the valuable agricultural fertilizer ammonia. Plants perform the chemical reduction of atmospheric nitrogen to ammonia...
