Stanford researchers find major food retailer's sustainability program drives farmers' environmental practices

When grocery stores tout sustainable products, consumers may take their claims at face value. Yet few studies have analyzed whether or not companies who claim to improve the sustainability of their products are actually changing practices in their supply chains.

U.S. Waterways Are Getting Saltier, With Possible Effects on Drinking Water

Streams and rivers across much of the U.S. are getting saltier and more alkaline due to an uptick in the use of road deicers and fertilizers in recent decades, according to a  50-year-long analysis of 232 monitoring sites by the U.S. Geological Survey.

More roads in grizzly bear habitat means more deaths

It’s simple math, says a University of Alberta conservation biologist. More roads equals fewer grizzly bears.

In a recent study examining a non-invasive DNA (hair collection) dataset of grizzly bear activity in British Columbia, Clayton Lamb and his colleagues determined what scientists have long suspected: higher road density leads to lower grizzly bear density—a critical problem for a species still rebounding from a long period of human persecution.

University of Windsor researcher champions collaborative freshwater research project

The Great Lakes will have a network of well-equipped guardians thanks to a plan hatched by a UWindsor researcher with funding from the Canada Foundation for Innovation and Ontario’s Ministry of Research, Innovation and Science and Ministry of Economic Development and Growth.

Aaron Fisk and his nine collaborators will receive $15.9 million for the Real-time Aquatic Ecosystem Observation Network (RAEON), a collaborative research project which will provide infrastructure and data management for Canadian scientists to carry-out cutting-edge research on freshwater ecosystems.

How Bioluminescent Deep Sea Creatures Are Helping Us in the Fight Against Cancer

A team of scientists at the Keck School of Medicine of USC is looking to some deep sea dwellers to create a better way to develop cancer-fighting therapies. Harnessing the power of the enzymes that give these marine animals the ability to glow, the team created a test that makes it easy for researchers to see whether a therapy is having its intended effect — killing cancer cells. The results of their study were published in Scientific Reports Jan. 9.

Kenyan Innovation Takes Plastic Bags Out of Forestry

Plastic bags are known for their environmental impact. They slowly release toxic chemicals once in the soil, for instance, and find their way into the guts of animals that often choke and die as a result.

Planets Around Other Stars Are Like Peas in a Pod

An international research team led by Université de Montréal astrophysicist Lauren Weiss has discovered that exoplanets orbiting the same star tend to have similar sizes and a regular orbital spacing. This pattern, revealed by new W. M. Keck Observatory observations of planetary systems discovered by the Kepler Telescope, could suggest that most planetary systems have a different formation history than the solar system.

Climate Change Drives Collapse in Marine Food Webs

University of Adelaide scientists have demonstrated how climate change can drive the collapse of marine “food webs”.

Tropical Cyclone Irving Appears Elongated in NASA Imagery

NASA's Aqua satellite passed over Tropical Cyclone Irving and found wind shear was stretching the storm out.

NASA Sees Tropical Cyclone Ava Fizzling South of Madagascar

NASA-NOAA's Suomi NPP satellite passed over the Southern Indian Ocean and captured a visible image of Tropical Cyclone Ava as it continued to move away from southeastern Madagascar and weaken.
