For the first time, researchers have directly measured a general law of how pedestrians interact in a crowd. This law can be used to create realistic crowds in virtual reality games and to make public spaces safer. People intuitively know how to navigate through crowds in a way that both minimizes distance traveled and avoids collisions. But the 'force' that governs human interactions has been previously unknown.

To bring facts and clarity to the public debate about immunization in light of the recent measles outbreak, the University of Pittsburgh Graduate School of Public Health unveiled a computer simulation that explores the impact of measles outbreaks in cities across the U.S. Users can see how an outbreak would play out if their city had high or low vaccination rates.
During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions “driven primarily” by human-induced global warming, a new study predicts. The research says the drying would surpass in severity any of the decades-long “megadroughts” that occurred much earlier during the past 1,000 years.
Scientists used supercomputers to find a new class of materials that possess an exotic state of matter known as the quantum spin Hall effect. The researchers published their results in the journal Science in December 2014, where they propose a new type of transistor made from these materials.
A hurricane is heading toward the coast. Weather forecasters predict strong winds, massive waves and intense rainfall. But what does that mean for you? Will your neighborhood be flooded? Should you evacuate?
A new online resource will help coastguards, meteorological organizations and scientific communities predict future storm surge patterns. The freely-accessible database has been compiled through the multi-partner, international eSurge project, which was launched in 2011 with the aim of making available observational data to improve the modeling and forecasting of storm surges around the world using advanced techniques and instruments.
Top researchers are using mathematical modelling and heavy computations to understand how the brain can both remember and learn. Ten years ago, when the team of Marianne Fyhn and Torkel Hafting Fyhn cooperated with the Nobel Prize winning team of May-Britt and Edvard Moser at NTNU, they discovered the sense of orientation in the brain.
Devize is cloud-based Monte Carlo simulation software designed to guide engineers through the entire simulation and optimization process. The Web-based application’s workflow allows users to simulate possible outcomes, and results are presented with straightforward explanations.
A breakthrough could lead to the more precise transfer of information in computer chips, as well as new types of optical materials for light emission and lasers. Researchers were able to control light at tiny lengths around 500 nanometers — smaller than the light’s own wavelength — by using random crystal lattice structures to counteract light diffraction. The discovery could begin a new phase in laser collimation.
Small magnetic whirls may revolutionize future data storage and information processing if they can be moved rapidly and reliably in small structures. A team of scientists has now been able to investigate the dynamics of these whirls experimentally.
Wrinkle Predictions: New Mathematical Theory may Explain Patterns in Fingerprints, Raisins, MicrolensesFebruary 2, 2015 2:00 pm | by Jennifer Chu, MIT | News | Comments
As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. While these patterns have long been observed in nature, and more recently in experiments, scientists have not been able to come up with a way to predict how such patterns arise in curved systems, such as microlenses.
TERATEC brings together top international experts in high performance numerical design and simulation, making it the major event in France and in Europe in this area. It emphasizes again the strategic importance of these technologies for developing industrial competitiveness and innovation capacity.
Researchers were able to predict the interactions of cancer cells using a part of game theory known as the public goods game, suggesting that work on the social interactions among cancer cells may provide insight into the dynamics of cancer. Researchers applied this model to the cooperation between producing and non-producing members of a cancer cell population, in order to examine if the model is also applicable to biological processes.

A major development in the venture, Seales is building software that will visualize the scrolls' writings as they would be if unrolled.
Just because concrete is the most widely used building material in human history doesn’t mean it can’t be improved. A recent study using DOE Office of Science supercomputers has led to a new way to predict concrete’s flow properties from simple measurements. The results should help accelerate the design of a new generation of high-performance and eco-friendly cement-based materials by reducing time and costs associated with R&D.
NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens. Developed by NASA's Jet Propulsion Laboratory in Pasadena, CA, OnSight will give scientists a means to plan and, along with the Mars Curiosity rover, conduct science operations on the Red Planet.
Is glass a true solid? Researchers have combined computer simulation and information theory, originally invented for telephone communication and cryptography, to answer this puzzling question. This puzzle of a material which seems solid to any observer while appearing fluid under the microscope is an old one. And, even with the help of today's supercomputers, it seems impossible to verify in simulations whether a glass ever stops flowing.
Wave equations help describe waves of light, sound and water as they occur in physics. Also known as partial differential equations, they have valuable potential for predicting weather or earthquakes, or certain types of natural disasters. Tao is interested in the theoretical side of these equations, seeking to discover with computer algorithms whether they can behave in a way that typically is the opposite of what occurs in the real world.
Visual-Environment 10.0 is a comprehensive simulation platform designed to enable the swift integration of calculations using the open source CFD modules of OpenFOAM.

In 2005, a semi-truck hauling 35,000 pounds of explosives through the Spanish Fork Canyon in Utah crashed and caught fire, causing a dramatic explosion that left a 30-by-70-foot crater in the highway. Fortunately, there were no fatalities. Such accidents are extremely rare but can, obviously, have devastating results. So, understanding better exactly how such explosions occur can be an important step to learning how better to prevent them.

Turbulent combustion simulations, which provide input to the design of more fuel-efficient combustion systems, have gotten their own efficiency boost. Researchers developed new algorithmic features that streamline turbulent flame simulations, which play an important role in designing more efficient combustion systems. They tested the enhanced code on the Hopper supercomputer and achieved a dramatic decrease in simulation times.
Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using supercomputing resources at NERSC, climate scientist Michael Wehner was able to complete a run in just three months. What he found was that not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.
