More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations. David...

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...

Charcoal From Wildfires Enters Waterways And Works Its Way To Oceans
2013-04-20 07:14:14

redOrbit Staff & Wire Reports - Your Universe Online New research claims charcoal created from wildfires does not remain in the soil as previously believed, but is instead transported into the sea by rivers, where it ultimately enters the carbon cycle. That determination was made by an international team of researchers, including Thorsten Dittmar from the Max Planck Institute for Marine Microbiology (MPI) in Bremen and Rudolf Jaffé from Florida International...

The True Fate Of Charcoal In The World's Soils Revealed
2013-04-19 08:35:43

National Science Foundation Scientists find surprising new answers in wetlands such as the Everglades Scientists have uncovered one of nature's long-kept secrets--the true fate of charcoal in the world's soils. The ability to determine the fate of charcoal is critical to knowledge of the global carbon budget, which in turn can help understand and mitigate climate change. However, until now, researchers only had scientific guesses about what happens to charcoal once it's...

How Some Leaves Get Fat: It's In Their Veins
2013-04-11 15:35:43

Brown University A "garden variety" leaf is a broad, flat structure, but if the garden happens to be somewhere arid, it probably includes succulent plants with plump leaves full of precious water. Fat leaves did not emerge in the plant world easily. A new Brown University study published in Current Biology reports that to sustain efficient photosynthesis, they required the evolution of a fundamental remodeling of leaf vein structure: the addition of a third dimension. Leaves, after all,...

New Insight Into Photosynthesis Provided By University Of Toronto-led Study
2013-04-05 09:22:49

University of Toronto Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis. Carotenoids, the same pigments which give orange color to carrots and red to tomatoes, are often found together in plants with chlorophyll pigments that harvest solar energy. Their main function is...

New Insights Could Lead To Better Catalysts For Water Splitting
2013-03-29 10:47:24

California Institute of Technology Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe. The finding suggests a new way of approaching the design of catalysts that drive the water-splitting reactions of artificial photosynthesis. "If we want to...

First Evidence Of Life Deep Under Oceanic Crust Realized
2013-03-15 12:56:53

Lee Rannals for redOrbit.com — Your Universe Online Scientists writing in the journal Science say they have found the first direct evidence of life in the deeply buried oceanic crust. Researchers on board the Integrated Ocean Drilling Program's (IODP) research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. After examining rock samples from this depth, they were able to uncover...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
