Scientists have developed a computer model that clarifies the complex processes driving ocean mixing in the vast eddies that swirl across hundreds of miles of open ocean. The model is a first-of-its-kind tool because of its ability to exploit the power available from today’s supercomputers. Global climate simulations are beginning to be able to resolve the largest mesoscale eddies, which are considered the “weather” of the ocean.
As the Atlantic hurricane season gets underway, communities in severe weather-prone regions are anxiously tracking pending storms and working to create effective disaster response plans. IBM, through an alliance with The Weather Company, has announced a new emergency management solution featuring sophisticated analytics and use of real-time weather data to help communities predict and plan for natural disasters far more accurately.
Pope Francis' plea to make the state of the environment a central moral issue of our age has been greeted with applause from climate activists and a wide range of church, science and government leaders, but dismissive shrugs from those who doubt climate change. In "Laudato Si," Francis addressed "every living person on this planet," urging them to hear "both the cry of the Earth and the cry of the poor."
Throughout history, many revolutions have started with the desire for democracy, and the simulation revolution is no exception. Simulation is an effective way to test the design of a product virtually. It's now evolving into building simulation apps that can be shared across teams, departments and companies. Simulation apps can help organizations in every industry gain better R&D results, while saving both time and money.

The plight of Malaysia Airlines flight 370 (MH370) is one of the biggest mysteries in aviation history, but an interdisciplinary research team led by a Texas A&M University at Qatar math professor has theorized the ill-fated plane plunged vertically into the southern Indian Ocean in March 2014.
Intelligent Light, in collaboration with scalable solver developers at Georgia Tech and HPC experts at Lawrence Berkeley National Laboratory, has announced that it is achieving breakthrough CFD scalability running the AVF-Leslie combustion simulation code on up to 64,000 cores on supercomputers at the Department of Energy’s National Energy Research Scientific Computing Center.
Here they are — the top most-visited stories from the past week. A 10-engine battery-powered plane that can take off like a helicopter, fascinating facts about USB OTG, a flexible computing prototype for electronic skin, a detailed look at the "Prostate Cancer Jungle," free Windows 10 upgrades, and an experiment that proves reality does not exist — at least until it is measured — are all among the top hits.
A new work based on 3-D supercomputer simulations of earthquake data has found hidden rock structures deep under East Asia. Researchers used seismic data from 227 East Asia earthquakes during 2007-2011, which they used to image depths to about 900 kilometers, or about 560 miles below ground. Notable structures include a high velocity colossus beneath the Tibetan plateau, and a deep mantle upwelling beneath the Hangai Dome in Mongolia.
Robots will one day provide tremendous benefits to society, such as in search and rescue — but not until they can learn to keep working when damaged. A paper shows robots automatically recover from injury in less than two minutes. A video of the work shows a six-legged robot adapt to keep walking even if two of its legs are broken. It also shows a robotic arm that learned how to correctly place an object even with several broken motors.
Every few years, unusual weather brings torrential rainfall and warm, nutrient-poor water to the coasts of Peru and Ecuador, devastating the fishing economies. Although this might seem like a local storm, the system — known as the El Niño–Southern Oscillation — has global effects. Typically, the next winter is much warmer in western North America, wetter in the southeastern United States, and drier in the Pacific Northwest.
Pope Francis, Once a Chemist, to Issue Document Laying out Moral Justification to Fight Global WarmingMay 27, 2015 2:47 pm | by Seth Borenstein, AP Science Writer | News | Comments
From Galileo to genetics, the Roman Catholic Church has danced with science, sometimes in a high-tension tango but more often in a supportive waltz. Pope Francis is about to introduce a new twist: global warming. Pope Francis, once a chemist, will soon issue an authoritative church document laying out the moral justification for fighting global warming, especially for the world's poorest billions.
Understanding how turbulence can alter the shape and course of a flock of birds, a swarm of insects or even an algal bloom could help us to better predict their impact on the environment. Now mathematicians have investigated for the first time how the surrounding fluid environment – such as air and water - can affect the shape of a model flock.
Computer simulations have predicted a new phase of matter, an atomically thin two-dimensional liquid. This prediction pushes the boundaries of possible phases of materials further than ever before. Two-dimensional materials themselves were considered impossible until the discovery of graphene around 10 years ago. However, they have been observed only in the solid phase, because the thermal atomic motion required for molten materials...
President Barack Obama said May 20, 2015, the threat posed by climate change is evident all around and that those who deny the "indisputable" science that it is real are putting at risk the security of the United States and the military sworn to defend it. Obama said refusing to act to slow the effects of global warming, including rising seas, amounts to a "dereliction of duty" and undermines the readiness of U.S. forces.
Dassault Systèmes announced that the first heart model from its “Living Heart Project” will be commercially available on May 29, 2015. Powered by Dassault Systèmes’ 3DEXPERIENCE platform’s realistic simulation applications, the commercial, high-fidelity scientifically validated 3-D simulator of a four-chamber human heart is the first product of its kind.
Detailed new field studies, laboratory experiments and simulations of the largest known “internal waves” in the Earth’s oceans — phenomena that play a key role in mixing ocean waters, greatly affecting ocean temperatures — provide a comprehensive new view of how these colossal, invisible waves are born, spread and die off. The paper is co-authored by 42 researchers from 25 institutions in five countries.
For more than a decade, mathematicians and computational scientists have been collaborating with earth scientists to break new ground in modeling complex flows in energy and oil and gas applications. Their work has yielded a high-performance computational fluid dynamics and reactive transport code dubbed Chombo-Crunch that could enhance efforts to develop carbon sequestration as a way to address Earth’s growing carbon dioxide challenges.
Computer simulation of the body’s inflammatory response to traumatic injury accurately replicated known individual outcomes and predicted population results. Researchers examined blood samples from 33 survivors of car or motorcycle accidents or falls for multiple markers of inflammation, including interleukin-6, and segregated the patients into categories of trauma severity. They were able to validate model predictions.
The German Climate Computing Center is managing the world's largest climate simulation data archive, used by climate researchers worldwide. The archive consists of more than 40 petabytes of data and is projected to grow by roughly 75 petabytes annually over the next five years. As climate simulations are carried out on increasingly powerful supercomputers, massive amounts of data are produced that must be effectively stored and analyzed.

A research team at the Georgia Tech Research Institute is studying a range of security challenges involving programmable logic devices — in particular, field programmable gate arrays. FPGAs combine hardware performance and software flexibility so well that they're increasingly used in aerospace, defense, consumer devices, HPC, vehicles, medical devices and other applications. But they come with potential vulnerabilities.
If you find yourself sweating out a day that is monstrously hot, chances are you can blame humanity. A new report links three out of four such days to man's effects on climate. And as climate change worsens around mid-century, that percentage of extremely hot days being caused by man-made greenhouse gases will push past 95 percent.
Researchers have invented a new technology that can increase the bandwidth of WiFi systems by 10 times, using LED lights to transmit information. The technology could be integrated with existing WiFi systems to reduce bandwidth problems in crowded locations, such as airport terminals or coffee shops, and in homes where several people have multiple WiFi devices.
Riedel-Kruse and his team are enabling people to interact with biological materials and perform experiments the way they interact with computers today — called interactive biotechnology. They have created three related projects that begin to define this new field. In the most far-reaching project, Riedel-Kruse created a robotic biology cloud lab capable of carrying out remote-control experiments.
