During the summer of 1997-1998, measurements of beam absorption and beam attenuation coefficients, and downwelling and upwelling irradiance were made in the Southern Ocean along a S-N transect at 6 de...
Earth Sciences |In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-...
Life Sciences |Mike Tice, a researcher in the Department of Geology and Geophysics at Texas A&M, says the findings could change current ideas about the earliest forms of life on Earth. The team includes scientists f...
Earth Sciences |University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel P...
Life Sciences |Their findings suggest that the early ocean was much more temperate and that, as a result, life likely diversified and spread across the globe much sooner in Earth's history than has been general...
Earth Sciences |Pecan, the most valuable nut tree native to North America, is native from northern Illinois and southeastern Iowa to the Gulf Coast of the United States, where it grows abundantly along the Mississipp...
Agricultural and Forestry Science |Scientists widely accept that around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change when oxygen levels rose sharply. Called the "Great Oxidation Event" (GOE),...
Earth Sciences |Most life on earth depends on the sun to provide the energy needed to sustain its function. For more than a billion years, photosynthesis—a mechanism that has evolved to perfection—has allowed plants ...
Power and Electrical Engineering |The expansion of rapid growth plantations such as those of eucalyptus came about in order to meet the needs of the growing paper pulp industry. Blights and diseases arose as one of the main threats to...
Agricultural and Forestry Science |Approximately 100,000 acres of forested area west of Lake Superior which make up the Boundary Waters Canoe Area was used for the study. Using computer models PnET-II and LANDIS-II, the researchers wer...
Agricultural and Forestry Science |The team, led by Penn State Assistant Professor of Biology Todd LaJeunesse, found that a rare species of algae that is tolerant of stressful environmental conditions proliferated in corals as the more...
Ecology, The Environment and Conservation |The new work demonstrates that the technology that uses algae as sentinels has broader applications than previously reported, according to authors Miguel Rodriguez Jr. and Elias Greenbaum of the Depar...
Ecology, The Environment and Conservation |Scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues at Creighton University have deciphered the highly unusual molecular structure of a naturally produced, ocean-bas...
Life Sciences |Technion professor Oded Béjà and colleagues suggest that the viruses, or marine phages, may use the genes to gain a competitive advantage over the bacteria they infect and other viruses. But the findi...
Ecology, The Environment and Conservation |Although plants have efficiently captured energy from sunlight for millions of years, producing light-harvesting and energy storage devices based on photosynthesis is no easy task. Now, a rese...
