Satellite imagery from NASA's Terra and Aqua satellites showed that Hurricane Katia had not moved much, just about 30 miles in 16 hours.

Thunderstorms directly above two of the world’s busiest shipping lanes are significantly more powerful than storms in areas of the ocean where ships don’t travel, according to new research.

Researchers from the University of California, Irvine and NASA’s Jet Propulsion Laboratory have reported the first observation of sea level “fingerprints,” tell-tale differences in sea level rise around the world in response to changes in continental water and ice sheet mass. The team’s findings were published today in the American Geophysical Union journal Geophysical Research Letters.

Hidden in plain sight – that’s how researchers describe their discovery of a new genus of large forest tree commonly found, yet previously scientifically unknown, in the tropical Andes.

The IAU has assigned names to fourteen geological features on the surface of Pluto. The names pay homage to the underworld mythology, pioneering space missions, historic pioneers who crossed new horizons in exploration, and scientists and engineers associated with Pluto and the Kuiper Belt. This is the first set of official names of surface features on Pluto to be approved by the IAU, the internationally recognised authority for naming celestial bodies and their surface features.

Positive emotions are often seen as critical aspects of healthy living, but new researchsuggests that the link between emotion and health outcomes may vary by cultural context. The findings, published in Psychological Science, a journal of the Association for Psychological Science, show that experiencing positive emotions is linked with better cardiovascular health in the US but not in Japan.

Hurricanes are the most violent storms on Earth. They form near the equator over warm ocean waters. Actually, the term hurricane is used only for the large storms that form over the Atlantic Ocean or eastern Pacific Ocean.

The Global Precipitation Measurement mission or GPM core satellite has been providing rainfall rates and cloud heights in tropical cyclones, and recently found towering thunderstorms that indicated strengthening in Tropical Storm Jose. Those "hot towers" were an indication the storm was strengthening and it later became a hurricane. 

Researchers at the University of Waterloo have invented a fast, affordable way for developing communities to test their drinking water for potentially deadly E. coli.

Unlike current tests that cost about $70 and can take up to three days to get back from the lab, the Waterloo invention uses paper strips similar to those in litmus tests to produce results in less than three hours at a cost of 50 cents.

Canadian scientists have discovered that certain lake predators are altering their behaviour due to climate change, revealing what the future may hold for these fish and their food.

For years scientists told tales of fish such as Lake Trout adapting their feeding behaviour as temperatures change, but no empirical evidence existed. Now, a recently completed 11-year study at IISD Experimental Lakes Area (IISD-ELA) in northwestern Ontario reveals that Lake Trout have a remarkable ability to adjust their behaviour in the face of changing water temperatures.
