The first institution-level model to estimate the amount of reactive nitrogen released into the environment—a contributor to smog, acid rain, and climate change—is enabling the University of Virginia to quantify its nitrogen footprint and take steps to reduce it. A detailed description of this cutting-edge tool and how it can help improve institutional sustainability is presented in Sustainability: The Journal of Record a publication of Mary Ann Liebert, Inc., publishers. The Open Access...

1 species of bacteria rides the other down through sediment like an elevator, then closes the loop on the ocean's nitrogen cycle In a discovery that further demonstrates just how unexpected and unusual nature can be, scientists have found two strains of bacteria whose symbiotic relationship is unlike anything seen before. Long, thin, hairlike Thioploca (meaning "sulfur braids" in Spanish) trichomes form chains down into marine sediment, which tiny anammox cells ride down like an...

Homes Of Giant Bacteria Invaded By Strangers

University of Southern Denmark Life is not a walk in the park for the world's largest bacteria, that live as soft, noodle-like, white strings on the bottom of the ocean depths. Without being able to fend for themselves, they get invaded by parasitic microorganisms that steal the nutrition, that they have painstakingly retrieved. This newly discovered bizarre deep ocean relationship may ultimately impact ocean productivity, report researchers from University of Southern Denmark now in the...

Nitrogen Fixation System Could Eliminate The Need For Chemical Fertilizers
2013-07-26 05:01:36

Brett Smith for redOrbit.com - Your Universe Online Plant scientists from the University of Nottingham in the United Kingdom have announced a revolutionary new system that allows plants to take nitrogen from the atmosphere and potentially eliminate the need for chemical fertilizers that can pollute the ecosystem where they are used. Plants must fix nitrogen and convert it to ammonia in order to survive and grow - however, only a few plants, such as peas and lentils, have the ability to...

A simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs), which could be used in dye-sensitized solar cells and fuel cells, is published in Scientific Reports today. The work, carried out at Ulsan National Institute of Science and Technology (UNIST) in South Korea, could be a step towards replacing conventional platinum (Pt)-based catalysts for energy conversion. The search for economically viable alternatives to fossil fuels has attracted...

In the world, there are a lot of small molecules people would like to get rid of, or at least convert to something useful, according to University of Wisconsin-Madison chemist Robert J. Hamers. Think carbon dioxide, the greenhouse gas most responsible for far-reaching effects on global climate. Nitrogen is another ubiquitous small-molecule gas that can be transformed into the valuable agricultural fertilizer ammonia. Plants perform the chemical reduction of atmospheric nitrogen to ammonia...

Oceans Of The Past Give Clues To The Future
2013-06-15 05:39:41

April Flowers for redOrbit.com - Your Universe Online The oceans of the past were quite different than the ones we see today. Ocean temperatures are increasing due to global warming, and these increases are harming marine food webs. Coastal dead zones are also being created by the run-off from fertilizers. An international team of researchers, led by McGill University, has completed the first global study of changes that occurred during the nitrogen cycle at the end of the last ice age....


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
