Researchers Discover Nitrogen in Soil Cleans the Air

Eutrophication harms the environment in many ways. Unexpectedly, nitrogen fertilizer may also be positive for the environment. And even acidic soils, promoting the destruction of forests, can have a positive effect. Researchers from the Biogeochemistry Department at the Max Planck Institute for Chemistry in Mainz found out that nitrogen fertilizer indirectly strengthens the self-cleaning capacity of the atmosphere.

Growth of Cities Endangers Global Environment

The explosive growth of cities worldwide over the next two decades poses significant risks to people and the global environment, according to a meta-analysis published today in Plos One.

Grassland Plant Species Play Import Roles in Biodiversity

Recent study of grasslands shows that species variety more important to ecosystem services than previously thought.

Wildlife Responds Three Times Faster to Climate Change Than Previously Predicted

New research by scientists in the Department of Biology at the University of York shows that species have responded to climate change up to three times faster than previously appreciated. These results are published in the latest issue of the leading scientific journal Science.

Study Reveals Bacteria From Dog Feces in Outdoor, Urbanized Air

Bacteria from fecal material -- in particular, dog fecal material -- may constitute the dominant source of airborne bacteria in Cleveland's and Detroit's wintertime air, says a new University of Colorado, Boulder study.

Ohio Wildlife Officer Indicted on Charges of Illegally Trafficking in White-Tailed Deer

A federal grand jury in Cincinnati, Ohio, returned a four-count indictment today charging Allan Wright, 45, of Russellville, Ohio, with trafficking in and making false records for illegally harvested white-tailed deer (Odocoileus virginianus) in violation of the Lacey Act.

Could Saltwater Make Microbial Life on Mars Possible?

How common are droplets of saltwater on Mars? Could microbial life survive and reproduce in them? A new million-dollar NASA project led by the University of Michigan aims to answer those questions.

Study Shows Human Sewage Kills Imperiled Coral

A research team from Rollins College in Florida and the University of Georgia has identified human sewage as the source of the coral-killing pathogen that causes white pox disease of Caribbean elkhorn coral. Once the most common coral in the Caribbean, elkhorn coral was listed for protection under the United States Endangered Species Act in 2006, largely due to white pox disease.



Human Health: Biofuels to Grow from Plant Research Center

Improved nutrition for billions of people around the world and the development of clean, green biofuels are two key aims of a major new research center at the University of Adelaide's Waite Campus.

Climate Change Could Drive Native Fish Out of Wisconsin Waters

The cisco, a key forage fish found in Wisconsin’s deepest and coldest bodies of water, could become a climate change casualty and disappear from most of the Wisconsin lakes it now inhabits by the year 2100, according to a new study.

'Momma's Boy' Phenomenon May Occur in Bird Families

Scientists have discovered that zebra finch mothers favor their sons over their daughters, so male chicks end up getting fed more than their sisters do. But fathers don't appear to be as biased.

Climate Change, Algae Lessen Lake Tahoe's Clarity

Lake Tahoe clarity dropped in 2010, but the rate of decline in clarity over the past decade remains slower compared with previous decades, according to UC Davis scientists who have monitored the lake for more than 40 years.

Another Study Finds Bluefin Tuna In Need of Protection

The team’s analysis—published in a recent issue of Science magazine’s Policy Forum—is the first study of global tuna and billfish populations using the methods of the International Union for Conservation of Nature (IUCN).

Ethane Levels Yield Information About Changes in Greenhouse Gas Emissions

Recent data from NSF-funded research in both Greenland and Antarctica demonstrate that fossil-fuel related emissions of both methane and ethane, two of the most abundant hydrocarbons in the atmosphere, declined at the end of the twentieth century, according to a paper published Thursday in the journal Nature.

Food for Thought: The Most Earth-Friendly Way to Dispose of Food Waste

Consider the apple core. From an environmental perspective, what’s the most responsible way to dispose of it, or a banana peel, or any food waste?

Sewage Still Plagues Hudson River

People are swimming in the Hudson again, and while clumps of sewage rarely float by anymore, the water is not reliably clean, according to a recent report released from the environmental group Riverkeeper.

Study Reveals Nature and Humans Quite Similar

World financial markets may be reeling from new setbacks, but it turns out there’s a secret economy right under our noses and it’s thriving. The movers and shakers, however, are plants and fungi.

Arctic Cruise Explores Changing Ocean Acidification

Scientists from the U.S. Geological Survey will embark on a research cruise to the Arctic Ocean beginning today to collect water samples and other data to determine trends in ocean acidification from the least explored ocean in the world.

Map Identifies Important Coral Reefs Exposed to Stress

The study, say the authors, will help to conserve some of the world’s most important coral reefs by identifying reef systems where biodiversity is high and stress is low, ecosystems where management has the best chance of success.

Scientists Investigate Link Between Human Populations and River Phosphorus Concentrations

High concentrations of phosphorus in aquatic ecosystems are often associated with human activities in the surrounding area, such as agriculture and urban development.
