Newly developed synthetic membranes provide a greener and more energy-efficient method of separating gases, and can remove CO2 and other greenhouse gases from the atmosphere, potentially reducing the cost of capturing CO2 significantly.

Climate Change Formula Isn’t Universal

September 15, 2014 7:00 am | by ETH Zurich | News | Comments

Based on models and observations, climate scientists have devised a simplified formula to describe one of the consequences of climate change: regions already marked by droughts will continue to dry out in the future climate. Regions that already have a moist climate will experience additional rainfall. However, this formula is less universally valid than previously assumed.


Ozone Layer is Recovering

September 11, 2014 2:00 pm | by Associated Press, Seth Borenstein | News | Comments

Earth's protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported in a rare piece of good news about the health of the planet. Scientists said the development demonstrates that when the world comes together, it can counteract a brewing ecological crisis.

Sharks May Not Smell Food in Acidic Water

September 11, 2014 7:00 am | by Georgia Institute of Technology | Videos | Comments

The increasing acidification of ocean waters caused by rising atmospheric CO2 levels could rob sharks of their ability to sense the smell of food, a new study suggests.

September 9, 2014 7:00 am | by MIT, David Chandler | News | Comments

Around the world, there is more salty groundwater than fresh, drinkable groundwater. For example, 60 percent of India is underlain by salty water. Now, an analysis shows that a different desalination technology called electrodialysis, powered by solar panels, could provide enough clean, palatable drinking water to supply the needs of a typical village.

Egyptian Art Paints Picture of Ecological Collapse

September 9, 2014 7:00 am | by UC Santa Cruz | News | Comments

Depictions of animals in ancient Egyptian artifacts have helped scientists assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years. A new analysis of this record shows that species extinctions, probably caused by a drying climate and growing human population in the region, have made the ecosystem progressively less stable.
