Scientists have used computer simulations to show how bacteria are able to destroy antibiotics — a breakthrough that will help develop drugs which can effectively tackle infections in the future. Researchers at the University of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it from working, making the bacteria resistant.

Mathematicians have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and trade of mathematics, the researchers hope this new formulation might ultimately lead to mathematical models that better reflect the inherent uncertainties of the natural world.
Certain primordial stars — those between 55,000 and 56,000 times the mass of our Sun, or solar masses — may have died unusually. In death, these objects — among the Universe’s first-generation of stars — would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
With President Obama announcing climate-support initiatives at the 2014 United Nations Climate Summit, the U.S. Department of Energy national laboratories are teaming with academia and the private sector to develop the most advanced climate and Earth system computer model yet created. For Los Alamos National Laboratory researchers, it is a welcome advance for an already vibrant high-performance computing community.
A computer model that accurately predicts how composite materials behave when damaged will make it easier to design lighter, more fuel-efficient aircraft. Innovative computer codes form the basis of a computer model that shows in unprecedented detail how an aircraft's composite wing, for instance, would behave if it suffered small-scale damage, such as a bird strike.
SDSC Joins Intel Parallel Computing Centers Program with Focus on Molecular Dynamics, Neuroscience and Life SciencesSeptember 12, 2014 2:44 pm | by San Diego Supercomputer Center | News | Comments
The San Diego Supercomputer Center (SDSC) at the University of California, San Diego, is working with semiconductor chipmaker Intel to further optimize research software to improve the parallelism, efficiency, and scalability of widely used molecular and neurological simulation technologies.
It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body. Using advanced optical techniques, the researchers measured the stiffness of the membrane surrounding red blood cells over time.
University of Hawaii at Manoa astronomer R. Brent Tully has led an international team of astronomers in defining the contours of the immense supercluster of galaxies containing our own Milky Way. They have named the supercluster “Laniakea,” meaning “immense heaven” in Hawaiian.
Ion channels are involved in many physiological and pathophysiological processes throughout the human body. A young team of researchers investigated how ion flux through a voltage gated sodium ion channel works in detail. Since this process is incredibly fast, computer simulations were performed to visualize sodium flux "in slow motion."
Hummingbirds can hover so well they seem to float in mid-air. With the help of a supercomputer, Vanderbilt University mechanical engineer Haoxiang Luo has fleshed out some of the secrets of how hummingbirds hover, flight that's more similar to that of an insect than the typical bird.
NASA's Tropical Rainfall Measuring Mission or TRMM Satellite provided a look under the hood of Hurricane Cristobal as it moved north and paralleling the U.S. East Coast. NASA's HS3 hurricane mission also investigated the storm. Cristobal is close enough to the coast to trigger high surf advisories.
MIT spinout Akselos has developed novel software, based on years of research at the Institute, which uses precalculated supercomputer data for structural components — like simulated “Legos” — to solve FEA models in seconds. Hundreds of engineers in the mining, power-generation, and oil and gas industries are now using Akselos software.
Argonne National Laboratory was one of seven new winners of the HPC Innovation Excellence Award. Announced by International Data Corporation at the ISC '14 supercomputer industry conference in Leipzig, Germany, the award recognizes noteworthy achievements by users of high-performance computing (HPC) technologies.
New research by University of Montana doctoral student Jared Oyler provides improved computer models for estimating temperature across mountainous landscapes. Oyler provided a new climate dataset for ecological and hydrological research and natural resource management.
Recently, the Harvard-Smithsonian Center for Astrophysics unveiled an unprecedented simulation of the universe’s development. Called the Illustris project, the simulation depicts more than 13 billion years of cosmic evolution across a cube of the universe that’s 350-million-light-years on each side. But why was it important to conduct such a simulation?
Creating a realistic computer simulation of how light suffuses a room is crucial not just for animated movies like Toy Story or Cars, but also in industry. Special computing methods should ensure this, but require great effort. Computer scientists from Saarbrücken have developed a novel approach that vastly simplifies and speeds up the whole calculating process.
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The group discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. The new technique gives scientists a way of controlling things adrift on water in a way that resembles sci-fi tractor beams.
A team representing Westinghouse Electric Company and the Consortium for Advanced Simulation of Light Water Reactors, a DOE Innovation Hub led by Oak Ridge National Laboratory, has received an HPC Innovation Excellence Award for applied simulation on Titan, the nation’s most powerful supercomputer. The award recognizes achievements made by industry users of high-performance computing technologies.
Using NASA's Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a "zombie star" after an unusually weak supernova explosion. A supernova typically obliterates the exploding white dwarf, or dying star. On this occasion, scientists believe this faint...
When the space shuttle Columbia disintegrated on re-entry in 2002, sophisticated computer models were key to determining what happened. A piece of foam flew off at launch and hit a tile, damaging the leading edge of the shuttle wing and exposing the underlying structure. Temperatures soared to thousands of degrees as Columbia plunged toward Earth at 27 times the speed of sound, said Gallis, who used NASA codes and Icarus for simulations...

The Columbia River basin in the Pacific Northwest offers great potential for water power; hydroelectric power stations there generate over 20 000 megawatts already. Now a simulation model will help optimize the operation of the extensive dam system.
Every trillionth of a second, Panagiotis Grammatikopoulos calculates the location of each individual atom in a particle based on where it is and which forces apply. He uses a computer program to make the calculations, and then animates the motion of the atoms using visualization software. The resulting animation illuminates what happens, atom-by-atom, when two nanoparticles collide.
Ensemble forecasting is a key part of weather forecasting. Computers typically run multiple simulations using slightly different initial conditions or assumptions, and then analyze them together to try to improve forecasts. Using Japan’s K computer, researchers have succeeded in running 10,240 parallel simulations of global weather, the largest number ever performed, using data assimilation to reduce the range of uncertainties.
