Studies have shown that both air pollution and impaired lung function can cause cognitive deficits, but it was unclear whether air pollution diminishes cognition by reducing breathing ability first or whether air pollution represents an independent risk factor for cognitive deficit. Now a new study conducted by German and Swiss researchers has answered that question: air pollution directly affects cognition and is not mediated by lung function.
A factor that determines the properties of clouds that help moderate the planet’s temperature may be decided in the oceans.
Climate change may be the driving force behind fewer, yet more powerful hurricanes and tropical storms, says a Florida State geography professor.
A chemical signature recorded on the ear bones of Chinook salmon from Alaska’s Bristol Bay region could tell scientists and resource managers where they are born and how they spend their first year of life.
Salmon carry a strontium chemical signature in their “ear bones” that lets scientists identify specific streams where the fish hatched and lived before they were caught at sea. The new tool may help pinpoint critical habitats for fish threatened by climate change, industrial development and overfishing.

To maximize such benefits as conserved biodiversity and sustained livelihoods, ecological restoration should increase ecological integrity, be sustainable in the long term, be informed by the past and future, and benefit and engage society.
Expansion of cattle pastures has led to the destruction of huge swaths of rain forest in Brazil, home to the world’s largest herd of commercial beef cattle. But a new study led by the University of Wisconsin-Madison’s Holly Gibbs shows that market-driven “zero deforestation agreements” have dramatically influenced the behavior of ranchers and the slaughterhouses to which they sell.
Scientists at South Dakota State University analyzed a half-mile slice of Western Antarctica ice core to help determine that climate change begins in the Arctic and moves southward, according to chemistry professor Jihong Cole-Dai of the SDSU Ice Core and Environmental Chemistry Lab. Since 2006, the SDSU research team have been part of a National Science Foundation project to uncover the secrets within the 2-mile long Western Antarctica Ice Sheet Divide ice core.
Citizen scientists tracking backyard bird feeders helped scientists pinpoint the climate forces that likely set the stage for boreal bird irruptions in which vast numbers of northern birds migrate far south of their usual winter range. The discovery could make it possible to predict the events more than a year in advance.
Climate helps drive the erosion process that exposes economically valuable copper deposits and shapes the pattern of their global distribution, according to a new study from researchers at the University of Idaho and the University of Michigan.
Researchers led by Luke Flory found that prescribed fires in areas invaded by stiltgrass were much more intense – with taller flames and much hotter fires – often reaching more than 500 degrees Fahrenheit. Those more intense fires killed tree seedlings and encouraged the spread of stiltgrass.

The Fishery Performance Indicators are the most comprehensive, global tool that considers social factors in addition to the usual biological measures when gauging a fishery's health. The new tool is described in a paper published May 6 in PLOS ONE.
Scores of young transgenic American chestnut trees developed at the SUNY College of Environmental Science and Forestry (ESF) will take root this spring across New York state, representing one more step in the restoration of a once-dominant species that has virtually vanished from the landscape.
About one in nine people globally still suffer from hunger with the majority of the hungry living in Africa and Asia. The world’s forests have great potential to improve their nutrition and ensure their livelihoods. In fact, forests and forestry are essential to achieve food security as the limits of boosting agricultural production are becoming increasingly clear.
A study in the Journal of Environmental Quality examined methods for recovering phosphorus from wastewater using mathematical modeling. . The study showed that a typical wastewater treatment plant could reclaim approximately 490 tons of phosphorus in the form of struvite each year.

A team of researchers from the University of California, Davis, the Wildlife Conservation Society, and other groups has focused its attention on fishery improvement projects (FIPs), which are designed to bring seafood from wild fisheries to the certified market, with only a promise of sustainability in the future. They conclude that FIPs need to be fine-tuned to ensure that fisheries are delivering on their promises.
More than 1,600 trained volunteers helped expand the reach and accuracy of long-term geographical tracking to predict the spread of sudden oak death in California. Results showed that trained citizen scientists were as effective as professionals in data collection, whether or not they had a professional background in science.

Several species of fish — including the peppered chub and the plains minnow — were found to be severely declining in the Great Plains.
Climate change is a perennially controversial subject frequently splashed across mainstream headlines. However, what we see in the news is not always what the scientists at the front line of climate change experience. Some scientists have been trying to counteract these misconceptions via citizen journalism and directly connecting with the public through blogging rather than official media channels.
A demographic study of two endangered plants at Point Reyes National Seashore north of San Francisco shows that they favor recently disturbed open areas over areas that have established plant cover. The study strengthens the case for removing the beachgrass originally planted to stabilize the dunes and allowing the sand to move in response to storm surges and strong tides.
The demand for more “AC” will also cause consumers to use more electricity causing stress on energy prices, infrastructure, and environmental policy, according to a new study.
The Indonesian National Police’s Criminal Investigation Division (BARESKRIM MABES POLRI), the Government of Indonesia, and the Wildlife Conservation Society’s Wildlife Crimes Unit (WCU) today announced the seizure of a shipment of pangolins headed to China and valued at approximately 1.8 million US dollars (USD). The pangolin smuggler involved in the case has been arrested.

University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times.
Assistant Professor of Oceanography Robert Spencer writes in Geophysical Research Letters that single-cell organisms called microbes are rapidly devouring the ancient carbon being released from thawing permafrost soil and ultimately releasing it back into the atmosphere as carbon dioxide. Increased carbon dioxide levels, of course, cause the Earth to warm and accelerate thawing.
Researchers at the University of New Hampshire have discovered a new method to detect a bacterium that has contaminated New England oyster beds and sickened consumers who ate the contaminated shellfish. The new detection method is a significant advance in efforts to identify shellfish harboring disease-carrying strains of Vibrio parahaemolyticus.
Five years ago the BP Deepwater Horizon oil platform exploded. The spill caused enormous environmental damage, but it also caused great stress among Gulf Coast residents. Even now, a significant percentage of people there continue to deal with anxiety, depression and other mental health issues, researchers say.
Researchers need to find ways to measure how the changes in climate are affecting biodiversity. One of the best places to look may be down at our feet, at beetles. That`s because, as a McGill research team discovered after doing the first large-scale survey of Arctic beetles, these six-legged critters are not only abundant in number but also diverse in feeding habits and what they eat is closely linked to the latitude in which they are found.
