Mineral weathering from thawing permafrost can release substantial CO2

Wed, 19 Sep 2018 11:58:53 EDT ~ The amount of carbon dioxide released from thawing permafrost might be greater than previously thought, according to a new study by ecologists. The research is the first to document the potential for substantial contributions of CO2 from thawing permafrost to the atmosphere through an inorganic process called mineral weathering.

Origami inspires highly efficient solar steam generator

Wed, 19 Sep 2018 11:14:59 EDT ~ Water covers most of the globe, yet many regions still suffer from a lack of clean drinking water. If scientists could efficiently and sustainably turn seawater into clean water, a looming global water crisis might be averted. Now, inspired by origami, the Japanese art of paper folding, researchers have devised a solar steam generator that approaches 100 percent efficiency for the production of clean water.

Green space near home during childhood linked to fewer respiratory problems in adulthood

Tue, 18 Sep 2018 18:05:04 EDT ~ Children who have access to green spaces close to their homes have fewer respiratory problems, such as asthma and wheezing, in adulthood, according to new research. In contrast, children who are exposed to air pollution are more likely to experience respiratory problems as young adults. Find out more...

Searching for clues on extreme climate change

Tue, 18 Sep 2018 08:20:57 EDT ~ Nearly 13,000 years ago, pines in southern France experienced a cold snap, which scientists have now reconstructed. The study about the consequences of a drastic climate change event in past and its implications for our future. Find out more...

Tropics are widening as predicted by climate models, research finds

Mon, 17 Sep 2018 15:36:15 EDT ~ Scientists have observed for years that Earth's tropics are widening in connection with complex changes in climate and weather patterns. But in recent years, it appeared the widening was outpacing what models predicted, suggesting other factors were at work. But a new paper finds that the most up-to-date models and the best data match up reasonably well. Find out more...

Air pollution affects thyroid development in fetuses

Mon, 17 Sep 2018 10:13:07 EDT ~ Soot and dust alters thyroid development in fetuses before they are born in smoggy cities, raising concern about health impacts later in life, new research shows. Scientists focused on more than 2,000 kids in smoggy Southern California as part of USC's ongoing Children's Health Study. Find out more...

First evidence that soot from polluted air is reaching placenta

Sun, 16 Sep 2018 15:27:04 EDT ~ Evidence of tiny particles of carbon, typically created by burning fossil fuels, has been found in placentas for the first time, in new research. Find out more...

Study shows toxic effects of oil dispersant on oysters following deepwater horizon spill

Thu, 13 Sep 2018 16:00:39 EDT ~ A new study finds that oysters likely suffered toxic effects from the oil dispersant Corexit 9500 when it was used to clean up the 2010 Deepwater Horizon oil spill. Researchers determined this by comparing the low levels of toxicity of oil, the dispersant and a mixture of the two on Eastern oysters. Find out more...

Trees reveal the evolution of environmental pollution

Thu, 13 Sep 2018 14:20:39 EDT ~ Chemical analysis of tipuana tree rings and bark by Brazilian researchers shows falling levels of heavy metal pollution in the air of So Paulo City, Southern Hemisphere's largest metropolis. Find out more...

Most fire in Florida goes undetected

Thu, 13 Sep 2018 13:45:58 EDT ~ A new study indicates that common satellite imaging technologies have vastly underestimated the number of fires in Florida, detecting only 25 percent of burned area. Find out more...
