Genes of autumn leaves mapped
It is not known what genes turn leaves yellow in the fall. However, scientists at Ume'å Plant Science Center, Ume'å University, and the Royal Institute of Technology in Stockholm (KTH) have managed to identify more than 2,400 genes that take part in the process. One of the most magnificent pageants of nature every year is when trees... view more... (2003-02-28)
Scientists discover new ocean current
Scientists at Georgia Tech have discovered a new climate pattern, the North Pacific Gyre Oscillation. This pattern explains, for the first time, changes in the water important in helping commercial fishermen understand fluctuations in the fish stock. They're also finding that as the Earth is warming, large fluctuations in these factors could help... view more... (2008-05-01)
Iron and biological production in the high-latitude North Atlantic
Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions. view more (2009-07-08)
Researcher turns brown algae phylogeny upside down
According to fellow phycologists, algae expert Stefan Draisma from the Leiden University has turned brown algae phylogeny completely upside down. His research shows that few of the currently assumed relationships between the orders are correct. Furthermore, it transpires that some simple species arose not earlier but later than more complex... view more... (2002-06-24)
NASA satellite detects red glow to map global ocean plant health
Researchers have conducted the first global analysis of the health and productivity of ocean plants, as revealed by a unique signal detected by a NASA satellite. view more (2009-05-29)
Coral Reef Resilience: Better Feeders Survive Bleaching
Coral bleaching, a stress response that turns rainbow-hued reefs into bone-white graveyards, is damaging reefs worldwide. But some corals survive. A Nature report identifies a new trait critical to coral resiliency - the ability to kick feeding rates into overdrive. view more (2006-04-27)

Carnegie Mellon rover heads to Atacama Desert for final mission in 3-year search for life
Carnegie Mellon University researchers and their colleagues from NASA's Ames Research Center, the universities of Tennessee, Arizona and Iowa, as well as Chilean researchers at Universidad Catolica del Norte (Antofagasta) are preparing for the final stage of a three-year project to develop a prototype robotic astrobiologist, a robot that can... view more...

Researchers visualize complex pigment mixtures in living cells
In a technical advance that could allow researchers to watch cells as they act during the process of photosynthesis, scientists have developed a method that extends the power of fluorescence-mediated bio-imaging to see discrete pigments inside live cells of bacteria. view more (2008-03-05)
Shelf-Life Science: Good Genes Could Stop Broccoli Going Bad
Broccoli is one of western Europe`s most popular and widely consumed vegetables. However, its shelf life is restricted to about 5 days at room temperature, making distribution and storage of the product difficult. Recent research presented today at the Society for Experimental Biology conference in Swansea could help us understand the genetics of... view more... (2002-04-10)
Climate change causes extreme changes to Antarctic Lakes
Results from a 20-year study reveal dramatic ecological changes to lakes in Antarctica caused by a 1°C temperature increase. The findings, reported this week in SCIENCE, are yet more evidence of extreme changes in the Antarctic Peninsula region. This area has experienced some of the most rapid warming of anywhere on Earth in the past 50 years... view more... (2002-01-21)
Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. view more (2009-11-10)
Antarctic icebergs: unlikely oases for ocean life
Icebergs have long gripped the popular imagination, whether as relatively run-of-the-mill floating hazards that cause "unsinkable' ships to founder or, more recently, as enormous breakaway pieces of ice the size of states or small countries. view more (2007-06-25)
Growing green roofs
One way to maximize the eco-friendly factor of a structure is to include a green roof-and this doesn't refer to the paint color. view more (2009-09-04)
Organic solar power
Solar cells made from conventional semiconductor materials such as silicon are becoming increasingly common. By contrast, cells which use organic dyes or electrically conductive plastics are relatively unknown. At the Hanover Fair: prototypes of such cells and possible applications. ----------- If solar power is to be generated in the future on a... view more... (2002-04-16)
World first in satellite-based monitoring of large lake areas
Satellite sensors operating in the visible wavelength region are now in use for the monitoring of oceanic waters. For the first time ever, Finnish scientists have demonstrated the practical usability of satellite data for the simultaneous monitoring of water quality in large lake and coastal regions. The project was carried out by the Laboratory... view more... (2002-04-15)
U.Va. Engineers Aim to Solve 'Burning' Computer Problem
f you've balanced a laptop computer on your lap lately, you probably noticed a burning sensation. That's because ever-increasing processing speeds are creating more and more heat, which has to go somewhere -- in this case, into your lap. view more (2008-09-30)
Plants grow bigger and more vigorously through changes in their internal clocks
Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature. view more (2008-11-24)
Einstein researchers' discover 'radiation-eating' fungi
Scientists have long assumed that fungi exist mainly to decompose matter into chemicals that other organisms can then use. But researchers at the Albert Einstein College of Medicine of Yeshiva University have found evidence that fungi possess a previously undiscovered talent with profound implications: the ability to use radioactivity as an energy... view more...

Breakthrough made in assessing marine phytoplankton health
Researchers from Oregon State University, NASA and other organizations said today that they have succeeded for the first time in measuring the physiology of marine phytoplankton through satellite measurements of its fluorescence - an accomplishment that had been elusive for years. view more (2009-05-29)
