Nitrogen fixation in the Atlantic Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. Their findings have potentially important implications for understanding global climate, both past and future. Nitrogen is an essential...

Sediment samples from methane cold seeps off California shed light on mystery Scientists have identified an unexpected metabolic ability in a symbiotic community of deep-sea microorganisms. It may help solve a lingering mystery about the world's nitrogen cycle. The element nitrogen is a critical part of amino acids, the building blocks of proteins, and therefore essential to all life. Although nitrogen is plentiful on Earth--it represents 78 percent of the atmosphere, by volume--the element...

After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. For decades, scientists thought they had a handle on the workings of an intricate natural mechanism known as the nitrogen cycle, essential to maintaining life on Earth. This process, one of nature's most elegant sleights-of-hand, shuttles nitrogen from the soils to the oceans to the atmosphere and back. A...

Climate change, land-use patterns are culprits, scientists to report at Ecological Society of America conferenceWhat do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles that involve all three.On August 4-5, 2009, scientists who study such cycles--biogeochemists--will convene at a special series of sessions at the Ecological Society of America (ESA)'s...

Thread-like fungi that grow in soils at high elevations may play an important role in restoring whitebark and limber pine forests in Canada. Montana State University professor Cathy Cripps is looking for ways to use fungi to help pine seedlings get a strong start. Cripps' is working with resource managers and visitor relations staff from Waterton Lakes National Park (WLNP). She is part of a project that aims to restore fire to the national park, reduce the impact of noxious weeds and restore...

Scientists and researchers are scouring the Palouse region from eastern Washington into the Idaho panhandle in hopes of finding more of the dwindling giant Palouse earthworms, The Associated Press reported. The almost elusive worm is said to secrete a lily-like smell when handled, spit at predators, and live in burrows 15 feet deep. There have been only a handful of sightings. Even though there has been little research done on the Palouse worm, conservationists are asking the Obama...

Biologists know that when plants battle for sNitrogen research shows how some plants invade, take over otherspace, often the actual battle is for getting the nitrogen.Now, research at the University of Nebraska-Lincoln gives important new information on how plants can change "nitrogen cycling" to gain nitrogen and how this allows plant species to invade and take over native plants.In an article published July 6 in the scientific journal Proceedings of the National Academy of Sciences, UNL...

An international collaboration of scientists has completed the genome sequencing of the Azotobacter vinelandii soil bacterium, U.S. researchers said. Scientists at the Virginia Bioinformatics Institute and Virginia Tech said the group's achievement uncovered important genetic information that will contribute to a more complete understanding of the biology of the soil-living bacterium. The work will also help advance research on A. vinelandii's role as a model study organism for investigation...

U.S. entomologists say a careful choice of nitrogen-fixing bacteria might provide soybean farmers protection against an invasion of soybean aphids. Pennsylvania State University researchers said soybeans are legumes -- plants that can have a symbiotic relationship with nitrogen-fixing bacteria called rhizobia and therefore do not need additional nitrogen fertilizer. Each type of legume -- peas, beans, lentils, alfalfa -- have their own rhizobia. Soybeans are from Asia and so there were...

The French cheese Reblochon gets its distinctive flavor from a previously unknown group of bacteria, British university researchers report. Using genetic fingerprinting, the researchers identified eight previously undiscovered microbes in the soft, creamy, brie-like cheese made in France's Savoy mountain region, a study published in the International Journal of Systematic and Evolutionary Microbiology said. It has always been thought the bacteria cheese makers were putting in at the start of...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
