Satellite imagery showed the large extent of the remnant clouds and rains from what was Hurricane Irma. Those remnants were blanketing about a quarter of the continental U.S. over the Ohio and Tennessee Valleys and east to the Mid-Atlantic States. 

NASA’s Terra satellite is one of many satellites keeping a close eye on Hurricane Jose and saw the storm between the Bahamas and Bermuda.

Two birds that look the same, but have songs so different they can’t recognize each other, should be considered distinct species, suggests new UBC research.

For many Canadians, summer time means time at the lake, swimming, fishing, boating, and relaxing. Nothing can spoil this experience like blue-green mats of muck, caused by algal blooms. These blooms negatively affect not only recreational activities but also put drinking water source, property values, wildlife, and human health at risk. In the 1970s, scientists discovered that the nutrient phosphorus caused algal blooms, which led to new regulations and improved sewage treatment. Nevertheless, blooms continue to plague many Canadian lakes. To investigate what might be happening, scientists looked to see whether phosphorus might be recirculating from the mud at the bottom of lakes back into the water.

Ian Gates describes each pebble of bitumen as resembling a liquid-filled headache capsule and, for an Alberta struggling to build pipelines, this tiny package could spell pain relief indeed.

Freshly patented and weeks away from pilot-scale production, the professor’s revolutionary heavy oil and bitumen pellets may finally provide a pipeline-free solution to getting Alberta’s largest oil reserves to market in a cheap, sustainable manner, while vastly reducing the environmental risk of transportation.

The legacies of empire have increased the vulnerability of Caribbean states to climate change, according to University of Warwick expert Dr Leon Sealey-Huggins.

Researchers at Caltech have developed a prototype miniature medical device that could ultimately be used in "smart pills" to diagnose and treat diseases. A key to the new technology—and what makes it unique among other microscale medical devices—is that its location can be precisely identified within the body, something that proved challenging before.

A spruce forest regeneration experiment in Interior Alaska that spanned nearly 30 years demonstrates which forest management practices produce the best results.

NASA's Aqua satellite measured cloud top temperatures in newly formed Tropical Depression 15E in the Eastern Pacific Ocean and found some strong storms. 

NASA calculated the rainfall left in the wake of now post-tropical cyclone Irma as it moved through the Caribbean Sea to landfall in Florida and then captured a night-time look at the storm as it moved over Georgia.
