Tiny microenvironments in the ocean hold clues to global nitrogen cycle
Fri, 20 Apr 2018 17:06:10 EDT
A new study shows that nitrogen-feeding organisms exist all over the deep ocean, and not just in large oxygen-depleted 'dead zones,' changing the way we think about the delicate nitrogen cycle.
Bottlenose dolphins recorded for the first time in Canadian Pacific waters
Thu, 19 Apr 2018 23:38:28 EDT
A large group of common bottlenose dolphins (Tursiops truncatus) have been spotted in Canadian Pacific waters -- the first confirmed occurrence of the species in this area.
Efforts to develop water recycling technologies
Wed, 18 Apr 2018 14:14:23 EDT
Scientists are working to develop water recycling technologies that will transform waste from unconventional oil and gas development into reusable water.
Cities and communities in the US losing 36 million trees a year
Wed, 18 Apr 2018 14:13:23 EDT
Nationally, urban/community tree cover declined from 42.9 percent to 42.2 percent between 2009-2014. This translates to losing an estimated 36 million trees or approximately 175,000 acres of tree cover annually.
Coho salmon die, chum salmon survive in stormwater runoff research
Wed, 18 Apr 2018 10:05:11 EDT
Scientists found that coho salmon became sick and nearly died, within just a few hours of exposure to polluted stormwater. But chum salmon showed no signs of ill-effects after prolonged exposure to the same water.
Warming planet led to peatland formation
Mon, 16 Apr 2018 15:56:26 EDT
Rising temperatures were a key driver of peatland formation after the last glacial maximum, according to new research.
Are the media all 'doom and gloom'? Not when it comes to coverage of our oceans
Mon, 16 Apr 2018 12:15:28 EDT
The news media are often accused by adopting a 'doom and gloom' tone, especially when it comes to coverage of the environment. However, a new study on how journalists report on the state of our oceans shows that view may be misguided.
Chemical sleuthing leads to detection of little-known flame retardant in the environment
Mon, 16 Apr 2018 10:11:46 EDT
Chemists have published research findings on their discovery of a new and relatively unknown flame retardant in the environment. Their study is the first to detect the potentially toxic chemical in North America.
Evidence mounts for Alzheimer's, suicide risks among youth in polluted cities
Fri, 13 Apr 2018 15:52:59 EDT
Researchers have published a new study that reveals increased risks for Alzheimer's and suicide among children and young adults living in polluted megacities.
Brief exposure to tiny air pollution particles triggers childhood lung infections
Fri, 13 Apr 2018 09:35:29 EDT
Even the briefest increase in airborne fine particulate matter PM2.5, pollution-causing particles that are about 3 percent of the diameter of human hair, is associated with the development of acute lower respiratory infection (ALRI) in young children, according to newly published research.
Actual fossil fuel emissions checked with new technique
Thu, 12 Apr 2018 13:08:26 EDT
Researchers have measured CO2 emissions from fossil fuel use in California and compared them to reported emissions. This is the first time fossil fuel emissions have been independently checked for such a large area.
Faster, cheaper wastewater treatment through improved oxidation reactions
Thu, 12 Apr 2018 13:08:13 EDT
Researchers have discovered a method to dramatically improve the way pollutants are removed from wastewater using Advanced Oxidation Processes (AOPs).
One-fifth of carbon entering coastal waters of eastern North America is buried
Thu, 12 Apr 2018 10:29:42 EDT
Coastal waters play an important role in the carbon cycle by transferring carbon to the open ocean or burying it in wetland soils and ocean sediments, a new study shows.
Lavas in the lab could lead miners to new iron ore deposits
Thu, 12 Apr 2018 08:57:34 EDT
Geologists have discovered that some magmas split into two separate liquids, one of which is very rich in iron. Their findings can help to discover new iron ore deposits for mining.
The changing chemistry of the Amazonian atmosphere
Wed, 11 Apr 2018 17:41:45 EDT
Researchers have been debating whether nitrogen oxides (NOx) can affect levels of OH radicals in a pristine atmosphere but quantifying that relationship has been difficult. Now, researchers have found that accompanying the increase of NOx concentration from urban pollution, daytime peak OH concentrations in the rainforest skyrocketed, increasing by at least 250 percent. These increased levels of OH concentrations in the Amazon atmosphere could lead to changes in atmospheric chemistry, cloud formation, and rainfall.
