A study led by researchers at Université de Montréal quantifies for the first time the maximum amount of nutrients - specifically, phosphorus - that can accumulate in a watershed before additional pollution is discharged into downriver ecosystems.

That average threshold amount is 2.1 tonnes per square kilometre of land, the researchers estimate in their study published today in Nature Geoscience. "Beyond this, further phosphorus inputs to watersheds cause a significant acceleration of (phosphorus) loss in runoff."

Saturn's largest moon, Titan, is unique among all moons in our solar system for its dense and nitrogen-rich atmosphere that also contains hydrocarbons and other compounds, and the story behind the formation of this rich chemical mix has been the source of some scientific debate.

Publishing a high-impact scientific article is a significant achievement for researchers. Being featured on the journal cover is even better.

A new study outlines advances in the field of catalysis research, with broad applications for innovative energy technology.

The combined impact of deforestation and wildlife exploitation on bird numbers is severely underestimated and could lead to some species becoming extinct, a joint study by the University of Sheffield and National University of Singapore has found.

Scientists focused on Sundaland - a hotspot of biodiversity in Southeast Asia, spanning Borneo, Sumatra, Java and Peninsular Malaysia - where habitat loss, and hunting and wildlife trades are particularly intense.

HOUSTON - (Oct. 5, 2018) - Rice University scientists have developed something akin to the Venus' flytrap of particles for water remediation.

Micron-sized spheres created in the lab of Rice environmental engineer Pedro Alvarez are built to catch and destroy bisphenol A (BPA), a synthetic chemical used to make plastics.

The research is detailed in the American Chemical Society journal Environmental Science & Technology.

Turbidity currents have historically been described as fast-moving currents that sweep down submarine canyons, carrying sand and mud into the deep sea. But a new paper in Nature Communications shows that, rather than just consisting of sediment-laden seawater flowing over the seafloor, turbidity currents also involve large-scale movements of the seafloor itself. This dramatic discovery, the result of an 18-month-long, multi-institutional study of Monterey Canyon, could help ocean engineers avoid damage to pipelines, communications cables, and other seafloor structures.

MADISON -- California mice are relatively solitary animals, but put two in a room and they'll talk each other's ears off.

In 2009, BEF-China began as a unique forest biodiversity experiment in collaboration between institutions in China, Germany and Switzerland. The large-scale project investigated the importance of tree species richness for the good functioning of forest ecosystems. Stands of trees comprising different numbers of species were planted - from monocultures to highly species-rich plots with 16 different tree species on an area of 670 square meter.

NASA's IMERG combines data from many satellites to provide a look at rainfall occurring around the world. Those rainfall data were combined with visible imagery from NASA-NOAA's Suomi NPP satellite to create a composite or fuller picture of Kong- Rey in the Northwestern Pacific Ocean as it weakened to a tropical storm.

The genomes of 25 UK species* have been read for the first time by scientists at the Wellcome Sanger Institute and their collaborators**. The 25 completed genome sequences, announced today (4 October) on the Sanger Institute's 25th anniversary, will lead to future studies to understand the biodiversity of the UK and aid the conservation and understanding of our species.
