New analysis of fossils reveal ancient bird had two tails
3-D printing allows scientists to design bacterial communities
By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
Explosive dynamic behaviour on Twitter and in the financial market

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.
Scientists use fossilized feces to reconstruct moa diet
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 ...
Siberian hamsters show what helps make seasonal clocks tick
Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping ...
Math explains history: Simulation accurately captures the evolution of ancient complex societies
The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence ...
