Manganese Oxidation Played Key Role In Formation Of Oxygen On Earth
2013-06-27 07:25:47

April Flowers for redOrbit.com - Your Universe Online Oxygen is a necessary component for the survival of most terrestrial life on Earth. The planet´s atmosphere, however, did not always contain this life-sustaining substance. How and when oxygenic photosynthesis — the process responsible for producing oxygen on Earth through the splitting of water molecules — first began has been considered one of the great science mysteries of our planet. A new study, led by...

Northern Biomass Of Earth Has Been Mapped And Measured
2013-06-26 07:53:13

ESA The biomass of the northern hemisphere’s forests has been mapped with greater precision than ever before thanks to satellites, improving our understanding of the carbon cycle and our prediction of Earth’s future climate. Accurately measuring forest biomass and how it varies are key elements for taking stock of forests and vegetation. Since forests assist in removing carbon dioxide from the atmosphere, mapping forest biomass is also important for understanding the global carbon...

Plants Resort To Math In Order To Survive Without Sunlight
2013-06-24 10:12:34

Brett Smith for redOrbit.com - Your Universe Online At night, plants must utilize nutrient reserves efficiently until dawn and new research from the John Innes Centre in England has found that some plants use basic math to survive without sunlight for photosynthesis. The British scientists said they were surprised to discover that Arabidopsis uses two different kinds of internal molecules to determine a rate for breaking down starch reserves. "This is the first concrete example in...

Quantum Secret In Photosynthesis Uncovered
2013-06-21 11:20:36

ICFO-The Institute of Photonic Sciences The efficient conversion of sunlight into useful energy is one of the challenges which stand in the way of meeting the world's increasing energy demand in a clean, sustainable way without relying on fossil fuels. Photosynthetic organisms, such as plants and some bacteria, have mastered this process: In less than a couple of trillionths of a second, 95 percent of the sunlight they absorb is whisked away to drive the metabolic reactions that provide...

Arctic Permafrost Melts And Releases Greenhouse Gases
2013-06-11 10:18:54

Brett Smith for redOrbit.com - Your Universe Online Conditions within Arctic permafrost soils prevent dead plants and animals from decomposing, resulting in layer upon layer of organic carbon being sequestered just beneath the topsoil. However, rising Arctic temperatures are causing these soils to thaw at unprecedented rates, and NASA scientists are currently looking into just how much greenhouse gas is being released through soil decomposition. Using NASA´s C-23 Sherpa...

Carbon Found To Leak From Land To Water
2013-06-11 09:35:26

April Flowers for redOrbit.com - Your Universe Online In general, scientists have thought that about half of the carbon emitted by human activities remains in the atmosphere, with the other half being stored in the oceans and on land. A new study, published in Nature Geoscience, suggests that human activity might be increasing the transition of carbon from land to rivers, estuaries and the coastal zones. This indicates that large quantities of anthropogenic carbon might be hidden in...

First Definitive Proof Of Bacteria-feeding Behavior In Green Algae
2013-05-24 12:41:52

[ Watch The Video Scientists Prove Green Algae´s Appetite for Bacteria ] American Museum of Natural History A team of researchers has captured images of green alga consuming bacteria, offering a glimpse at how early organisms dating back more than 1 billion years may have acquired free-living photosynthetic cells. This acquisition is thought to have been a critical first step in the evolution of photosynthetic algae and land plants, which, in turn, contributed to the increase in...

Amazon River Found To Be A Metabolic Hotspot
2013-05-21 07:12:37

April Flowers for redOrbit.com - Your Universe Online The Amazon rainforest is known as the lungs of the planet because it inhales carbon dioxide and exudes oxygen into the atmosphere. The plants of the forest use the carbon dioxide to promote leafy growth, which eventually falls to the ground and decomposes or washes away from the region´s plentiful rainfall. Until recently, the belief was that most of the rainforest´s carbon floated away on the Amazon River, ending up deep...

Rising From The Primordial Soup
2013-05-20 05:53:48

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online One of the key elements to understanding the proliferation of life on Earth is modeling how electron transfer — the passage of an electron from one element to another — can be catalyzed. But the environmental conditions on Earth some 3 billion years ago were much different than they are today. For one, there was a distinct lack of molecular oxygen in the atmosphere, because it is readily absorbed and...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
