A new study could help explain the driving force behind the largest mass extinction in the history of earth, known as the End-Permian Extinction. The event, also known as the Great Dying, occurred around 250 million years ago when a...
Within a shrouded New Zealand forest, a tree stump keeps itself alive by holding onto the roots of its neighboring trees, exchanging water and resources through the grafted root system. New research, publishing July 25 in iScience, details how surrounding...

For the first time, scientists have shown through direct satellite observations of the ozone hole that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion. Measurements show that the decline in chlorine, resulting from an international ban on...
In the new study, the researchers combined tree physiology, ecology, and evolution to construct a new model in which tree species and their niches coevolve in mutual dependence.Image Credit:Flickr/ChrisA1995 Forests, especially tropical forests, are home to thousands of species...

A slab of rock from a study site in Nevada harbors many specimens of Metabolograptus extraordinarius, a shallow-water graptolite species, which together with some close relatives, replaced all the formerly dominant species following the end-Ordovician mass extinction. Credit: Charles...
At the Colorado River delta, cheniers of dead clam shells epitomize the carbon dioxide being added to the atmosphere upstream.Credit: Jansen Smith/Provided Scientists have begun to account for the topsy-turvy carbon cycle of the Colorado River delta -- once a...
The sky sometimes has its limits, according to new research from two University of Chicago atmospheric scientists. A study published May 24 in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream,...
A new class of self-forming membrane to separate carbon dioxide from a mixture of gases has been developed by Newcastle University researchers. Operating like a coffee filter, it lets harmless gases, such as nitrogen, exit into the atmosphere and then...
