Researchers drawing on 100-year-old sources of salmon data have found that recent returns of wild adult sockeye salmon to the Skeena River—Canada’s second largest salmon watershed— are 75 per cent lower than during historical times

How do big-game animals know where to migrate across hundreds of miles of vast Wyoming landscapes year after year?

Researchers at the University of Waterloo have developed a way to better harness the volume of energy collected by solar panels. 

The recent increase in fires adds to the concern from the international scientific community that the Amazon could turn from a wet and fire-resistant jungle into a savannah-like tinder box that would contribute to the rising levels of atmospheric carbon dioxide.

The U.S. Coast Guard crew gently guides a pair of ultra-fine meshed nets, to the deck of the Healy, where they land with a slight thud.

In a first-ever study investigating the risk of neonicotinoid insecticides to ground-nesting bees, University of Guelph researchers have discovered at least one species is being exposed to lethal levels of the chemicals in the soil.

Buoyed by an atmospheric “superhighway,” smoke from lightning-sparked African savanna and forest fires deposit unexpectedly large amounts of nutrient-rich phosphorus in a river basin an ocean away.

Climate change is altering the ability of the Southern Ocean off the West Antarctic Peninsula to absorb carbon dioxide, according to a Rutgers-led study, and that could magnify climate change in the long run.

In addition to their role in plant fertilization and reproduction, pollens and spores have another, hidden talent: With a simple treatment, these cheap, abundant and renewable grains can be converted into tiny sponge-like particles that can grab on to pollutants and remove them from water, scientists report. Even better, these treated particles don’t trigger allergies.

A new species of gigantic tumbleweed once predicted to go extinct is not only here to stay — it’s likely to expand its territory.
