Deforestation is likely to warm the climate even more than originally thought, scientists warn.

An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.

Wildlife species are being exposed to high levels of rat poison in northwest California, with illegal marijuana farms the most likely source point, according to a study led by the University of California, Davis, with the California Academy of Sciences.

Light is an important cue for nearly all life on Earth. Plants use light for photosynthesis, animals use light to set sleep cycles, and marine organisms use light to find food, avoid predators and even hide in plain sight.

Chinook salmon, an iconic species in the Pacific Northwest that supports a major fishery industry and indigenous traditions, have lost up to two-thirds of their genetic diversity over the past 7,000 years, according to a new study. Scientists warn the loss could make it difficult for the species to cope with warming global temperatures and ocean acidification — environmental changes that are already impacting the fish today.

A paper appearing in Geophysical Research Letters uses machine learning to craft an improved model for understanding geothermal heat flux — heat emanating from the Earth’s interior — below the Greenland Ice Sheet. It’s a research approach new to glaciology that could lead to more accurate predictions for ice-mass loss and global sea-level rise.

One of the most puzzling questions in breast cancer research is why some tumors stay put, while rogue cells from others break free and spread to surrounding tissues, the first step toward creating a more lethal disease. Although researchers have found some signs in mutated genes or telltale proteins on the cell’s surface, those discoveries don’t tell the whole story.

Princeton University researchers have found that the climate models scientists use to project future conditions on our planet underestimate the cooling effect that clouds have on a daily — and even hourly — basis, particularly over land.

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.

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.
