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 ...
New insights solve 300-year-old problem: The dynamics of the Earth's core
Scientists at the University of Leeds have solved a 300-year-old riddle about which direction the centre of the earth spins.
Biologists develop new method for discovering antibiotics
Biologists at the University of California, San Diego have developed a revolutionary new method for identifying and characterizing antibiotics, an advance that could lead to the discovery of new antibiotics to treat antibiotic ...
Monkey business: Researchers discover primitive forms of wealth
(Phys.org) —Comparisons between the stock market floor and a zoo are not far from the mark, according to a new study published today in the journal Proceedings of the National Academy of Sciences (PNAS) ...
Microbes help beetles defeat plant defenses
Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack rather than that of a chewing herbivore, according to a team of Penn State researchers who ...
