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...

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 world-leading team of academic researchers and industrial experts from across Europe are celebrating the conclusion of a four-year research collaboration tackling the challenges posed by the fastest and most powerful computing systems on the planet. The 4.2M Euro ParaPhrase project brought together academic and industrial experts from across Europe to improve the programmability and performance of modern parallel computing technologies.
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.
COMSOL 5.1 is a major upgrade that delivers new and enhanced functionality across all products, including COMSOL Multiphysics and the Application Builder and COMSOL Server, as well as the add-on modules. Among the significant updates are enhancements to numerous core modeling and simulation capabilities and an improved user experience for application design.
Simply declaring a region as a nature protection area is not enough, regular monitoring of its ecological condition is also necessary. New methods are being developed to monitor Europe’s vast number of nature protection areas from the air. Short laser pulses are sent to the ground, and information on the status of the habitat can be deduced from the reflected light signals using elaborate computer algorithms.
A consortium of European space scientists has succeeded in establishing a common data hub that allows the comparison of data from numerous space missions. A task that until now was hampered by different data processing protocols of individual space missions. Furthermore, observational data can now easily be compared with theoretical numerical models — regardless of the protocols used.
A young doctor leans over a patient who has been in a serious car accident and invariably must be experiencing pain. The doctor's trauma team examines the patient's pelvis and rolls her onto her side to check her spine. They scan the patient's abdomen with a rapid ultrasound machine, finding fluid. They insert a tube in her nose. Throughout the procedure, the patient's face remains rigid, showing no signs of pain.

A 60-year-old math problem first put forward by Nobel laureate Enrico Fermi has been solved. In 1955, a team of scientists led by Fermi used a computer for the first time to try to solve a numerical experiment. The outcome wasn’t what they were expecting, and the complexity of the problem underpinned the then-new field of non-linear physics and paved the way for six decades of new thinking. Chaos theory is just one of the theories...

Scientists have produced a new map of the Moon’s most unusual volcano showing that its explosive eruption spread debris over an area much greater than previously thought. A team of astronomers and geologists studied an area of the lunar surface in the Compton-Belkovich Volcanic Complex. By mapping the radioactive element thorium, which spewed out during the eruption, they discovered debris was able to cover an area the size of Scotland.
Solving Puzzle-Like Bond for Biofuels: First Look at One of Nature's Strongest Biomolecular InteractionsMarch 17, 2015 3:02 pm | by Texas Advanced Computing Center | News | Comments

The attack takes place at the climax of the blockbuster Avatar: Rockets slam into the Pandora inhabitants’ homeland tree. Explosions, flames and thick clouds of smoke appear on the screen. To keep the audience pinned to the edge of their seats, the images must be realistic. But the simulation of physical processes is especially tough to implement. This includes representation of liquids and gasses, which fall into the category of fluids.
