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....

Scientists Uncover Secrets Of Biological Soil Crust Microbes
2013-06-14 18:39:19

Brett Smith for redOrbit.com — Your Universe Online A new study from the Lawrence Berkeley National Laboratory in Berkeley, California has found the biological soil crust (BSC) layer of a desert contains microbes that lie in wait for the ideal conditions to begin metabolic activity. “We found a way to measure from start to finish in real unaltered samples the molecular events behind the response of cyanobacterium to wetting and drying in a desert BSC,” said...

The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality. Researchers from the Center of Plant Genomics and Biotechnology at the Technical University of Madrid (UPM) and the Advanced Photon Source (APS) at the U.S. Department of...

A new global-scale modeling study that takes into account nitrogen — a key nutrient for plants — estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen. Researchers at the University of Illinois at Urbana-Champaign and the University of Bristol Cabot Institute published their findings in the journal Global Change Biology. The findings will be a part of the upcoming Fifth Assessment...

Atmospheric Nitrogen Levels Have Remained Stable Over Past 500 Years Despite Widespread Emissions
2013-03-21 16:16:59

Brett Smith for redOrbit.com - Your Universe Online Despite widespread use of fertilizers and nitrogen emissions by industrial processes, the amount of atmospheric nitrogen has remained consistent over the past 500 years, according to a new study in Nature. "People have been really interested in nitrogen in current times because it's a major pollutant," said study co-author Kendra McLauchlan, an assistant professor of geography at Kansas State University. "Humans are producing a lot...

Alpine Glaciers Important For Carbon Cycle 091812

Alan McStravick for redOrbit.com - Your Universe Online On the surface, the term “carbon cycle” can seem cold and almost prosaic. It´s a term that many of us learned and came to understand in a third-grade science class, with the help of rudimentary illustrations of the sun shining down on the grass that the cow was about to devour for lunch and oversized arrows tracing the flow of energy for us. Like many things we learned in those early classes, it was diluted down to...

Research study in “Nature” confirms improved method by marine scientists from Kiel In order to predict how the Earth´s climate develops scientists have to know which gases and trace elements are naturally bound and released by the ocean and in which quantities. For nitrogen, an essential element for the production of biomass, there are many unanswered questions. Scientists from Kiel, Bremen and Halifax have now published a research study in the international journal...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have engineered a soft autonomous robot that crawls across surfaces similar to how an earthworm moves. The robot developed by researchers at MIT, Harvard University and Seoul National University is made almost entirely of soft materials, giving it the ability to be stepped on and inch away without a dent. The "Meshworm" robot has an "artificial muscle" that was created from wire made of nickel and titanium. Researchers...
