Heterogeneous parallel computing combines various processing elements with different characteristics that share a single memory system. Normally multiple cores (like the 'multicores' in some smart phones or personal computers) are combined with graphic cards and other components to process large quantities of data."We hope to help transform code so that it can be run in…

Climate and energy scientists at the Department of Energy's Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise."For the first time, we were able to apply data at a high enough resolution to be relevant," said ORNL's Melissa Allen,…

A new U of T Scarborough study has identified "superstar" varieties of rice that can reduce fertilizer loss and cut down on environmental pollution in the process.The study, authored by U of T Scarborough Professor Herbert Kronzucker in collaboration with a team at the Chinese Academy of Sciences, looked at 19 varieties of rice to…

A new study projects that global warming could dramatically affect the tundra breeding habitat of 24 shorebird species, with 66 percent to 83 percent losing most of their suitable nesting territories. Researchers modeled breeding conditions for these migratory shorebird species — some of which travel more than 10,000 miles from Antarctica or southern South America…

The preference of Heliconius butterflies for certain leaf shapes is innate, but can be reversed through learning. These results support a decades-old theory for explaining the evolution of the exceptional diversity of leaf shapes in passionflowers.The tropical butterfly Heliconius eratodistinguishes between shapes, and uses them as a cue for choosing the plants on which to feed and lay…

BUILDING IN RHODE Island isn’t easy. Hurricanes and tropical storms barrel through its quaint coastline towns, interrupting perfect summer weekends. Freezing winters bring blizzards that can shut down the entire state. And every season features corrosive salty winds, biting at the coast as if sent by a Britain still seething at the first American colony to…

A new acoustic buoy recently deployed by scientists from the Woods Hole Oceanographic Institution (WHOI) and WCS's (Wildlife Conservation Society) New York Aquarium to listen for some of the world's biggest animals in the New York Bight has detected its first whale species, and it's a really big one.Fixed in position some 22 miles south…

Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.The finding is reported in the July 29 issue ofScience and was funded by the National Science Foundation and the U.S. Department of Energy.…

A new study of over 1 million people finds that doing at least one hour of physical activity per day, such as brisk walking or cycling for pleasure, may eliminate the increased risk of death associated with sitting for 8h a day.Physical inactivity is linked to an increased risk of heart disease, diabetes and some…

Video surveillance is the most effective method for detecting animals flying around solar power towers, according to a study of various techniques by the U.S. Geological Survey and its partners at the Ivanpah Solar Electric Generating System facility in southeastern California.This study is the first to examine a variety of remote sensing and sampling techniques to determine…
