Selfless heroism isn't the best strategy in life-and-death disaster situations involving groups of people, a new study from the University of Waterloo suggests.
High-strength, lightweight steels can finally be processed on an industrial scale, thanks to a breakthrough in controlling undesired brittle stages from production, by WMG, University of Warwick.
Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.
Three million measurement points in one square kilometer: Prof. Xiaoxiang Zhu and her team have set a world record in information retrieval from satellite data. Thanks to new algorithms, the researchers from the Technical University of Munich (TUM) succeeded in making four-dimensional point clouds of Berlin, Las Vegas, Paris and Washington, D.C. from images stacks of the TerraSAR-X radar satellite. Next the scientists plan to create four-dimensional models of all cities in the world.
The wide reach of corrosion, a multitrillion-dollar global problem, may someday be narrowed considerably thanks to a new, better approach to predict how metals react with water.
The hundreds of hydroelectric dams proposed for the Amazon River Basin will cause massive environmental damage all the way from the eastern slopes of the Andes to the Atlantic Ocean. About one-third of the 428 dams are built or are under construction. The environmental effects will ramify throughout the river system and beyond. The largest river system on Earth, the Amazon River and its watershed cover 6.1 million square kilometers and includes nine countries.
UBC engineers have developed a more resilient type of concrete using recycled tires that could be used for concrete structures like buildings, roads, dams and bridges while reducing landfill waste.
Tropical peatlands have been disappearing fast due to clear-cutting and drainage projects. Now, new research from MIT shows peatlands face another threat, as climate change alters rainfall patterns, potentially destroying much of what remains and turning these carbon sinks into net carbon sources.
In an effort to design cleaner coal power plants, RWTH Aachen University researchers have been using High Performance Computing Center Stuttgart resources to perfrom some of the most detailed multiphase turbulence simulations ever run. The team recently released results in the Journal of Fluid Mechanics.
An increase in mean temperature of 0.5 degrees Celsius over half a century may not seem all that serious, but it's enough to have more than doubled the probability of a heat wave killing in excess of 100 people in India, according to researchers at the University of California, Irvine and other institutions.
