Nitrogen fertilizer remains in soils and leaks towards groundwater for decades
Nitrogen fertilizer applied to crops lingers in the soil and leaks out as nitrate for decades towards groundwater – "much longer than previously thought," scientists in France and at the University of Calgary ...
Crystal mysteries spiral deeper, chemists find
New York University chemists have discovered crystal growth complexities, which at first glance appeared to confound 50 years of theory and deepened the mystery of how organic crystals form. But, appearances can be deceiving.
Normal wear could explain differences in hominin jaw shapes
Mathematician devises a means for tying impact of teaching quality to pupil's future earnings
New analysis of fossils reveal ancient bird had two tails
New finding shows climate change can happen in a geological instant
(Phys.org) —"Rapid" and "instantaneous" are words geologists don't use very often. But Rutgers geologists use these exact terms to describe a climate shift that occurred 55 million years ago.
Water in stratosphere plays key role in Earth's climate
Water vapor changes in the stratosphere contribute to warmer temperatures and likely play an important role in the evolution of Earth's climate, says a research team led by a Texas A&M University professor.
Acidity can change cell membrane properties, study shows
Of all the amazing technologies humans have developed, none has matched the complexity of the fundamental building block of nature: the living cell. And none of the cell's activities would be possible without thin lipid membranes, ...
Discovery offers bio-solution to severe canola crop losses
A genetic discovery by a University of Calgary-led international research team offers a solution to a long-standing "green seed problem" that causes millions of dollars annually in canola crop losses.
Chemists find binding site of protein that allows plant growth
Using a new and super-sensitive instrument, researchers have discovered where a protein binds to plant cell walls, a process that loosens the cell walls and makes it possible for plants to grow.
New gut bacterium discovered in termite's digestion of wood
When termites munch on wood, the small bits are delivered to feed a community of unique microbes living in their guts, and in a complex process involving multiple steps, these microbes turn the hard, fibrous ...
Researchers create accurate computer model of RNA tetraloop
A computational model developed by researchers at Rensselaer Polytechnic Institute is the first to accurately simulate the complex twists of a short sequence of RNA as it folds into a critical hairpin structure ...
Study: Methane leaks from gas drilling not huge
Drilling and fracking for natural gas do not seem to spew immense amounts of the greenhouse gas methane into the air, as has been feared, a new study says.
Early-warning system to prevent fishery collapse discovered
Threats from overfishing can be detected early enough to save fisheries— and livelihoods —with minimal adjustments in harvesting practices, a new study by researchers in the University of Minnesota's ...
