Diverting urine away from municipal wastewater treatment plants and recycling the nutrient-rich liquid to make crop fertilizer would result in multiple environmental benefits when used at city scale, according to a new University of Michigan-led study.

Not all specimens of the same species are the same: there is a marked variability within the same population and sometimes these morphological differences are translated into a different behaviour.

Antarctic iceberg A-68A has drifted menacingly close to a remote island in the southern Atlantic Ocean.

A serious drought has flared up across half of the United States—a familiar story for the past two decades.

Correcting for the double-ITCZ bias, a persistent error in many climate models, reveals that future U.S. Southwest winters will be drier than expected

Forecasts predicting where plants and animals will inhabit over time rely primarily on information about their current climate associations, but that only plays a partial role. 

A University of Oklahoma-led interdisciplinary study on a decade-long experiment (1997-2009) at the University of Minnesota found that lower nitrogen levels in soil promoted release of carbon dioxide from soils under high levels of atmospheric carbon dioxide, and could therefore contribute to furthering rising atmospheric greenhouse gases and climate change.

The vast majority of nutrients and sediment washed into streams flowing into the Chesapeake Bay are picked up by deluges from severe storms that occur on relatively few days of the year. 

Coral reefs are one of the most biodiverse ecosystems on the planet supporting an estimated 25% of all marine species. 

The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas.
