Bacterium sequenced makes rare form of chlorophyll
Researchers at Washington University in St. Louis and Arizona State University have sequenced the genome of a rare bacterium that harvests light energy by making an even rarer form of chlorophyll, chlorophyll d. Chlorophyll d absorbs "red edge," near infrared, long wave length light, invisible to the naked eye. view more (2008-02-05)
Enzymatic reaction rate surprises researchers
Enzymatic reactions, which are crucial in biological processes, can occur much faster than previously thought possible, as researchers at the biophysics department of the Faculty of Exact Sciences of the Vrije Universiteit Amsterdam have discovered. Their findings were published on line on 5 May in Nature Structural Biology (www.nature.com/nsb).... view more... (2003-05-07)
Researchers decode genetics of rare photosynthetic bacterium
A bacterium that harvests far-red light by making a rare form of chlorophyll (chlorophyll d) has revealed its genetic secrets, according to a team of researchers who recently sequenced the bacteria's genome. view more (2008-02-11)
Light-protection for food packaging
Oxygen and light can alter the taste of foodstuffs. Manufacturers of packaging materials therefore try to protect contents from their influence. The latest approach is to use natural dyes in transparent plastic wrappers that selectively filter light. view more (2002-02-01)
Entire lakes feel effects of climate warming, University of Alberta study shows
Climate warming brought on in part by human activities is producing major ecological changes in remote arctic lakes at an alarming rate. view more (2005-10-19)
Envisat captures first image of Sargassum from space
Sargassum seaweed, famous in nautical lore for entangling ships in its dense floating vegetation, has been detected from space for the first time thanks to an instrument aboard ESA's environmental satellite, Envisat. view more (2007-06-07)
Nutrient-poor oceans generate their food "hot spots"
The oceans have their desert zones, in other words areas poor in nutrients and unfavourable for phytoplankton to develop. Half of the southern Pacific thus consists of great expanses of warm water with an average temperature of 28 °C (a greater surface area than Europe), which receives no input of deep-source cold water, rich in nutrient... view more...

Engineering algae to make fuel instead of sugar
In pursuing cleaner energy there is such a thing as being too green. Unicellular microalgae, for instance, can be considered too green. view more (2008-12-17)
Odd energy mechanism in bacteria analyzed
Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry - an advance that may ultimately help shed light on the ecology of the world's oceans. view more (2005-11-04)
Berkeley Researchers Identify Photosynthetic Dimmer Switch
In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular "dimmer switch" that helps control the flow of solar energy moving through the system of light harvesting proteins. view more (2008-05-09)
Innovative Research Technique Reveals Another Natural Wonder in Yellowstone Park: A Unique, Photosynthesizing Life-Form
In the hot springs of Yellowstone National Park, a team of researchers partially funded by the National Science Foundation (NSF) discovered a new bacterium that transforms light into chemical energy. view more (2007-07-27)
First step to converting solar energy using 'artificial leaf'
An international team of researchers has modified chlorophyll from an alga so that it resembles the extremely efficient light antennae of bacteria. view more (2009-06-30)
Scientists offer new view of photosynthesis
During the remarkable cascade of events of photosynthesis, plants approach the pinnacle of stinginess by scavenging nearly every photon of available light energy to produce food. Yet after many years of careful research into its exact mechanisms, some key questions remain about this fundamental biological process that supports all life on earth. view more (2007-05-04)
Why are autumn leaves red in America and yellow in Europe?
Walking outdoors in the fall, the splendidly colorful leaves adorning the trees are a delight to the eye. In Europe these autumn leaves are mostly yellow, while the United States and East Asia boast lustrous red foliage. view more (2009-08-13)
NASA predicts nongreen plants on other planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems. view more (2007-04-11)
Tiptoe through the tulips
Scientists have discovered that plant leaves activate defence mechanisms against plant eating insects within twenty seconds of an insect walking across them. Dr Alan Bown will be presenting the results of his footsteps research at the Society for Experimental Biology conference on Tuesday 9 April. view more (2002-04-04)
Duke scientists explain gaps in nutrient availability within North Atlantic
Duke University oceanographers have developed an explanation for why a vast North Atlantic circulation zone can have a large variability in nutrient supplies needed to sustain ocean plants and, by extension, support the food web of marine life. view more (2005-09-29)
Research tracks whales by listening to sounds
Researchers have developed a new tool to help them study endangered whales - autonomous hydrophones that can be deployed in the ocean to record the unique clicks, pulses and calls of different whale species. view more (2006-01-03)
Scientists ponder plant life on extrasolar Earthlike planets
When we think of extrasolar Earth-like planets, the first tendency is to imagine weird creatures like Jar Jar Binks, Chewbacca, and, if those are not bizarre enough, maybe even the pointy-eared Vulcan, Spock, of Star Trek fame. view more (2007-06-20)
Orchids and fungi -- partners for life
Three Thai orchids have been found to rely on a wide range of fungi to help them take carbon out of the soil instead of producing their own organic carbon. view more (2009-08-14)
