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...

New Insight Into Photosynthesis Provided By University Of Toronto-led Study
2013-04-05 09:22:49

University of Toronto Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis. Carotenoids, the same pigments which give orange color to carrots and red to tomatoes, are often found together in plants with chlorophyll pigments that harvest solar energy. Their main function is...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
