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...

Extreme Weather Adds To Warming
2013-08-15 05:05:21

redOrbit Staff & Wire Reports - Your Universe Online Extreme weather and climate events such as heavy precipitation, violent storms, heat waves and lengthy droughts cause terrestrial ecosystems to absorb approximately 11 billion tons less carbon dioxide each year, according to new research appearing in the latest edition of the journal Nature. That is equivalent to approximately one-third of global CO2 emissions each year, according to an international team of researchers led by...

Optimum spectral output shows increased yield using LED plant grow lights. Atlanta, GA (PRWEB) August 08, 2013 TruLite LED has officially released their latest update and adjustment to spectral output for their LED plant grow lights. Through continuous research and development of their solid state chip configuration, yields just keep getting better. The use of specific colors in very precise wavelengths in their grow lights is important as research continues. These tweaks are done to...

Australian Soil Carbon Loss From Dust Storms And Erosion
2013-08-07 05:31:49

April Flowers for redOrbit.com - Your Universe Online A new study from The Commonwealth Scientific and Industrial Research Organization (CSIRO) of Australia shows that although topsoil is rich in nutrients and carbon, it is increasingly being blown away by events such as the "Red Dawn" in Sydney in 2009. The amount and location of soil carbon is changed when wind lifts carbon dust into the atmosphere. Some of the carbon falls back to the ground, some leaves Australia and some ends up in...

Purple Bacteria Survive Extreme Alien Light
2013-07-24 09:36:16

April Flowers for redOrbit.com - Your Universe Online Purple bacteria, which have been around longer than most other organisms on the planet, contain pigments that allow them to use sunlight as their energy source. Neil Johnson, a University of Miami (UM) physicist who studies these magenta microbes, recently discovered they can also survive in the presence of extreme alien light. The findings, published online in Nature's Scientific Reports, show the way in which light is received by...

Variations In Earth’s Carbon Dioxide Levels Regulated By Tropical Ecosystems
2013-07-23 13:25:45

CSIRO Rising temperatures, influenced by natural events such as El Nino, have a corresponding increase in the release of carbon dioxide from tropical forest ecosystems, according to a new study out today. The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1 degree C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on...

New Variability In Iron Supply To The Oceans With Climate Implications Discovered By Scientists
2013-07-19 09:44:51

National Oceanography Centre, Southampton (UK) The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction. Iron is key to the removal of carbon dioxide from the Earth's atmosphere as it promotes the growth of microscopic marine plants (phytoplankton), which mop up the greenhouse gas and lock it away in the ocean. A new study, led by researchers based at the...
