A new NASA-led study using data from the Arctic Boreal Vulnerability Experiment (ABoVE) shows that carbon in Alaska's North Slope tundra ecosystems spends about 13 percent less time locked in frozen soil than it did 40 years ago. In other words, the carbon cycle there is speeding up -- and is now at a pace more characteristic of a North American boreal forest than of the icy Arctic.

An infrared look by NASA's Terra satellite found powerful storms in the center of Tropical Storm Shanshan, the newest tropical storm in the Northwestern Pacific Ocean. Shanshan has triggered warnings in the Marianas Islands. 

Hurricane Hector has a small, tight center surrounded by strong storms. Infrared satellite imagery provides temperature data, and when NASA's Aqua satellite passed over Hector the coldest cloud tops circling the center were compact.

Abandoned farmlands hold potential for the preservation of wetland and grassland birds as rehabilitation zones.

Almost everyone who eats fast food is familiar with the frustration of trying to squeeze every last drop of ketchup out of the small packets that accompany french fries.

Researchers have found that people exposed to air pollution levels well within UK guidelines have changes in the structure of the heart, similar to those seen in the early stages of heart failure.

Canada’s first research vessel dedicated exclusively to historic Hudson Bay – a landmark for scientific research in Canada’s North – will leave port in Summerside, PEI this week to explore some of the most understudied regions of the Arctic.

Canadian researchers have built and validated an online calculator that empowers individuals to predict their risk of cardiovascular disease.

NASA's Terra satellite analyzed Hurricane Hector in infrared light to find the strongest parts of the storm. Overnight from Aug. 1 to Aug. 2, Hector strengthened into a hurricane in the Eastern Pacific Ocean.

A team of researchers from Cologne and New York present proposals for the traffic management of the future. A dynamic and fair toll for road use could reduce congestion.
