Cane toad pioneers speed up invasions
Evidence contradicts idea that starvation caused saber-tooth cat extinction
The latest study of the microscopic wear patterns on the teeth of the American lions and saber-toothed cats that roamed North America in the late Pleistocene found that they were living well off the fat of ...
Fluctuating environment may have driven human evolution
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
Curiosity providing new weather and radiation data about Mars
(Phys.org)—Observations of wind patterns and natural radiation patterns on Mars by NASA's Curiosity rover are helping scientists better understand the environment on the Red Planet's surface.
Future heat waves pose threat to global food supply, study says
Heat waves could significantly reduce crop yields and threaten global food supply if climate change is not tackled and reversed.
The water cycle amplifies abrupt climate change
During the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread environmental change in western Europe. Thus, the ...
Team finds receptors that help plants manage environmental change, pests and wounds
ATP (adenosine triphosphate) is the main energy source inside a cell and is considered to be the high energy molecule that drives all life processes in animals and humans. Outside the cell, membrane receptors ...
Light variation drives community structure of a hypersaline microbial mat
When scientists at Pacific Northwest National Laboratory took samples of a microbial mat community from a hypersaline lake to study community responses to environmental changes, they expected to find that ...
How bacteria respond so quickly to external changes
Understanding how bacteria adapt so quickly to changes in their external environment with continued high growth rates is one of the major research challenges in molecular microbiology. This is important not least for our ...
Groundbreaking deepwater fossil study reveals reef's past and future
(Phys.org) —Many people look back at their time on the Great Barrier Reef by viewing holiday snaps. Scientists have taken an even longer look back at the Great Barrier Reef via another image caught in time - deepwater fossils ...
Oceanic 'dead zones' and Jurassic extinction
Data collected by a scientist now at the University of Liverpool has predicted a dramatic decline in the size of marine animals used as food by humans, due to reduced oxygen levels in the oceans.
New study tests 90-year old hybridisation theory
(Phys.org) —Massey University researchers have the first convincing evidence that interbreeding between closely related species (hybridisation) can aid plants during periods of environmental change.
Using genes to rescue animal and plants from extinction
(Phys.org) —With estimates of losing 15 to 40 percent of the world's species over the next four decades – due to climate change and habitat loss, researchers ponder in the Sept. 26 issue of Nature whether science should ...
China's synthetic gas plants would be greenhouse giants
Coal-powered synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according ...
