Researchers Question Published No-till Soil Organic Carbon Sequestration Rates
Nature » Soil, Organic »
University of Illinois College of Agricultural, Consumer and Environmental Sciences − URBANA, Ill. For the past 20 years, researchers have published soil organic carbon sequestration rates. Many of the research findings have suggested that soil organic carbon can be sequestered by simply switching from moldboard or conventional tillage systems to no-till systems. However, there is a growing body of research with evidence that no-till systems in corn and soybean rotations without cover crops, small grains, and forages may not be increasing soil organic carbon stocks at the published rates.

Space » Flare, Intense »
NASA/Goddard Space Flight Center − The sun emitted a mid-level solar flare, peaking at 9:03 a.m. EDT on April 18, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.
Researchers Find 3-million-year-old Landscape Beneath Greenland Ice Sheet
Nature » Ice, Greenland »
NASA/Goddard Space Flight Center − Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything — vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice.
Plants with Dormant Seeds Give Rise to More Species
Biology » Seeds, Dormancy »
National Evolutionary Synthesis Center (NESCent) − Durham, NC — Seeds that sprout as soon as they're planted may be good news for a garden. But wild plants need to be more careful. In the wild, a plant whose seeds sprouted at the first warm spell or rainy day would risk disaster. More than just an insurance policy against late frosts or unexpected dry spells, it turns out that seed dormancy has long-term advantages too: Plants whose seeds put off sprouting until conditions are more certain give rise to more…
Ancient DNA Offers Clues to How Barnyard Chickens Came to Be
Biology » Chickens, Gourds »
National Evolutionary Synthesis Center (NESCent) − Durham, NC — Ancient DNA adds a twist to the story of how barnyard chickens came to be, finds a study to be published April 21 in the journal Proceedings of the National Academy of Sciences. Analyzing DNA from the bones of chickens that lived 200-2300 years ago in Europe, researchers report that just a few hundred years ago domestic chickens may have looked far different from the chickens we know today.
MRI, on a Molecular Scale
Technology » Magnet, Magnetic »
Harvard University − For decades, scientists have used techniques like X-ray crystallography and nuclear magnetic resonance imaging (NMR) to gain invaluable insight into the atomic structure of molecules, but such efforts have long been hampered by the fact that they demand large quantities of a specific molecule and often in ordered and crystalized form to be effective – making it all but impossible to peer into the structure of most molecules.
