All the Energy You Need … from Tiny Leaves
Aug 1, 2009 — On a warm summer afternoon, you may find yourself on a leisurely walk through bucolic meadows or toiling under the glare of the sun because the lawn just won’t mow itself, but why not let the grass do some work and earn its keep? Grass, as does...
When things don’t go swimmingly
CAMBRIDGE, Mass. — Tiny single-celled creatures known as phytoplankton form the base of the ocean’s marine food web and, together, produce half the world’s oxygen. Generally speaking, if all goes well, these creatures, of which there are many species, swim to the...
UV LEDs Enrich Lettuce
WASHINGTON, May 18, 2009 -- Exposure to light provided by ultraviolet LEDs makes lettuce darker and redder, boosting the levels of healthy antioxidants it contains, according to a team of plant physiologists. Steven Britz of the US Department of Agriculture in Beltsville,...
Green Bacteria Harvests Light
UNIVERSITY PARK, Pa., May 5, 2009 – The structure of chlorophyll molecules in green bacteria that are responsible for harvesting light energy were determined by an international team of scientists. The discovery could one day be used to build artificial photosynthetic systems, like...
Laser Exposes Photosynthesis
LONDON, Feb. 9, 2009 – Instant pictures showing how the sun's energy moves inside plants have been taken for the first time, according to a newly released study. The images unravel some of the inner workings of the most efficient solar energy process on earth –...
Make Like a Plant
CAMBRIDGE, Mass., June 25, 2008 -- Guess you could say that researchers at the Massachusetts Institute of Technology (MIT) have themselves a bit of plant envy. This particular group of researchers is focused on harnessing energy from the sun because they are adament that it is the...
Park Microbe Harvests Light
BOZEMAN, Mont., July 26, 2007 -- For only the third time in the past 100 years, a novel bacterium has been found that transforms sunlight into chemical energy in the colorful microbial mats around the hot springs of Yellowstone National Park. The park is known as a tourists'...
Electron Study Could Lead to Better Lighting, Electronics
CAMBRIDGE, Mass., Nov. 30, 2006 -- New research into the behavior of electrons and how they function in some molecular systems, including photosynthesis, could lead to improvements in devices such as electronics, solar cells and lighting. MIT assistant chemistry professor Troy...
Self-Cleaning Lotus Mimicked for PV Arrays, Nonstick MEMS
ATLANTA, Oct. 13, 2006 -- Some of nature's best nonstick surfaces -- the leaves and flowers of the lotus plant -- are being duplicated in the lab to help create more reliable electric transmission systems, photovoltaic arrays that retain their efficiency, MEMS...
Biological Switch Created from Spinach Molecule
ATHENS, Ohio, Sept. 6, 2006 -- Scientists have transformed a spinach molecule of chlorophyll-a into a complex biological switch that has possible future applications for green energy, technology and medicine. The study offers the first detailed image of chloropyhll-a -- the...
