ATLANTA, Feb. 7, 2014 /PRNewswire/ -- Nature's key to optimum health. BIO RE-NETICS: An Interview with One World Media Radio on Anti-aging. Radio Interview: http://www.youtube.com/watch?v=U1uNn3YWRqE&feature=youtu.be (Logo: http://photos.prnewswire.com/prnh/20140121/CL49606LOGO) Sheffield Marketing Group: "We've found through very costly and extensive research that by replacing aging cells with new stem cells infused with chlorophyll, it converts the light from the sun to...

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...

Process For Chameleon-like Changes In World's Most Abundant Phytoplankton Uncovered
2012-11-27 10:36:33

Indiana University IU seeks patent for discovery with implications for health care, climate change research An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the world's most abundant ocean phytoplankton, once known as blue-green algae, to maximize light harvesting for photosynthesis. Responsible for contributing about 20 percent of...

Scientists have designed a screening tool that provides a fast, easy and relatively inexpensive way to predict levels of a specific toxin in lakes that are prone to blue-green algal blooms. Blue-green algae is not your average pond scum - rather than consisting of plant-like organisms, blue-green algae actually are cyanobacteria, and some species are linked to the production and release of the toxin microcystin into the water. Human exposure to the toxin through drinking or recreational...

The future of clean green solar power may well hinge on scientists being able to unravel the mysteries of photosynthesis, the process by which green plants convert sunlight into electrochemical energy. To this end, researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC), Berkeley have recorded  the first observation and characterization of a critical physical phenomenon behind photosynthesis known...

'Taco shell' proteinResearchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis.Robert Blankenship, Ph.D., Markey Distinguished Professor of biology and chemistry in Arts & Sciences, led a team that for the first time combined chemical labeling with mass spectroscopy to verify the orientation. The team also...

By Altun, Ahmet Yokoyama, Shozo; Morokuma, Keiji ABSTRACT The protein environments surrounding the retinal tune electronic absorption maximum from 350 to 630 nm. Hybrid quantum mechanical/molecular mechanical (QM/MM) methods can be used in calculating excitation energies of retinal in its native protein environments and in studying the molecular basis of spectral tuning. We hereby review recent QM/MM results on the phototransduction of bovine rhodopsin, bacteriorhodopsin, sensory rhodopsin...
