redOrbit Staff & Wire Reports - Your Universe Online A type of bacteria growing in a hot spring near Yellowstone National Park in Montana uses a previously unidentified process to harvest energy and produce oxygen from sunlight, according to new research published in a recent edition of the journal Science. The bacteria grows in far-red light, researchers from the Pennsylvania State University, the University of California, Davis, and Montana State University report in their study,...

Flexible Tapes From The Nanoworld
2014-08-15 03:03:26

Technische Universität München Dr. Wilhelm Auwärter and his team are working on a research project to develop tiny flat molecule tapes at the Department of Physics of Technische Universität München (TUM). These structures could find versatile applications. Via direct coupling on a silver surface, the scientists successfully formed dimers and short chains of porphine molecules without contaminating by-products. Porphyrin molecules are essential to many biological processes, such as...

International Science Team Solves Long-standing Mystery In Biology
2014-07-14 03:20:16

University of Leicester An international team of researchers, led by the University of Leicester, has solved a long-standing mystery in biology, by identifying the molecular structure of a vital biological chemical. The debate – which has raged within the scientific community for years – boils down to something as simple as a hydrogen atom: is it there, or is it not? The controversy centers around a form of enzyme called a heme (or haem, as in haemoglobin) at the center of which is...

The Scripps Research Institute Scientists from the Florida campus of The Scripps Research Institute (TSRI) have discovered a surprising new role for a pair of compounds—which have the potential to alter circadian rhythm, the complex physiological process that responds to a 24-hour cycle of light and dark and is present in most living things. At least one of these compounds could be developed as a chemical probe to uncover new therapeutic approaches to a range of disorders, including...

PARMAX™ Professional Series Hybrid LED Pro Panels excel in two critical lighting fundamentals for plants. First, intensity, the more intensity (quantity) of light the better your plants will grow and the second being, spectrum, as light intensity increases, light spectrum becomes more important. (PRWEB) June 03, 2014 PARMAX™ Professional Series Hybrid LED Pro Panels grow lights made by Smart Grow Technologies are much more energy efficient than standard HID (High Intensity Discharge)...

Aquatic Algae Can See A Wide Spectrum Of Light
2014-05-02 03:00:50

[ Watch The Video: Algae “See” A Wide Spectrum Of Light ] Andy Fell, UC Davis Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. The study by researchers at UC Davis was published earlier this year in the journal Proceedings of the National Academy of Sciences. Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the...

Novel biological mechanism relays electrons in proteins in mineral-breathing bacteria important for energy-related research Researchers simulating how certain bacteria run electrical current through tiny molecular wires have discovered a secret Nature uses for electron travel. The results are key to understanding how the bacteria do chemistry in the ground, and will help researchers use them in microbial fuel cells, batteries, or for turning waste into electricity. Within the bacteria's...

Lab-made Complexes Absorb More Sunlight
2013-08-21 15:47:02

Washington University in St. Louis A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennas that absorb more sunlight than fully natural ones In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles into a structure that soaks up sunlight. The scientists who made it...
