A new study finds polar bears in the wild have higher metabolic rates than previously thought, and as climate change alters their environment a growing number of bears are unable to catch enough prey to meet their energy needs.

A new study led by Northern Illinois University meteorologist Victor Gensini identifies a method for predicting the likelihood of damaging hailstorms in the United States—up to three weeks in advance.

Imagine a world where allergies, asthma and related chronic diseases are rare. Better yet, imagine a world where these conditions can be prevented before they develop.

A powerful new database being created by SFU genomics and bioinformatics researcher Fiona Brinkman and her team will help Canadian researchers make that world a reality.

Like many engineers, Ravi Selvaganapathy, McMaster’s Canada Research Chair in Biomicrofluidics, enjoys a challenge – the thornier, the better. His work focuses on developing small machines and tools (the “micro” in “biomicrofluidics”) and using them to improve medicine, biology and human health (the “bio”).

His latest project is about as thorny as it gets: a three-year, $1.8 million project funded by the University of Saskatchewan’s Global Water futures project to develop water sensors that can be used in resource-poor areas.

Two viruses closely related to Zika – West Nile and Powassan – can spread from an infected pregnant mouse to her fetuses, causing brain damage and fetal death, according to a new study from Washington University School of Medicine in St. Louis. The findings suggest that Zika may not be unique in its ability to cause miscarriages and birth defects.

A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a study led by the University of California, Davis. The study traces the emissions to fertilized soils in the Central Valley region.

NASA analyzed a major tropical cyclone spinning in the Southwestern Indian Ocean and measured its rainfall.

Omega-3s from fish pack a stronger punch than flaxseed and other oils when it comes to cancer prevention, according to a first-ever University of Guelph study.

Prof. David Ma has discovered that marine-based omega-3s are eight times more effective at inhibiting tumour development and growth.

The Global Precipitation Measurement mission or GPM core satellite passed over Tropical Cyclone Fehi in the Southern Pacific Ocean season and identified heavy rainfall in the system.

When NASA's Aqua satellite passed over Tropical Cyclone Cebile it measured cloud top temperatures and saw its eye circled by an impressive ring of powerful thunderstorms just before it went through eyewall replacement.
