The Galápagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved.
Astronomers at the University of Washington have developed a new method of gauging the...

Lawrence Livermore has joined forces with two other national labs to deliver next generation supercomputers able to perform up to 200 peak petaflops (quadrillions of floating point operations per second), about 10 times faster than today's most powerful high performance computing (HPC) systems.
Multi-scale Simulation Software for Chemistry Research Developed Using Trestles and Gordon SupercomputersFebruary 19, 2014 6:48 pm | by San Diego Supercomputer Center | News | Comments
Researchers at the San Diego Supercomputer Center at the University of California, San Diego, have developed software that greatly expands the types of multi-scale QM%2FMM (mixed quantum and molecular mechanical) simulations of complex chemical systems that scientists can use to design new drugs, better chemicals, or improved enzymes for biofuels production.
Black holes may be dark, but the areas around them definitely are not. These dense, spinning behemoths twist up gas and matter just outside their event horizon, and generate heat and energy that gets radiated, in part, as light. And when black holes merge, they produce a bright intergalactic burst that may act as a beacon for their collision.
First Commercial GPU-Accelerated Fluid Dynamics Solver Dramatically Speeds Simulation of Large Multiphysics ModelsFebruary 12, 2014 4:25 pm | by ANSYS | News | Comments
ANSYS users can now leverage NVIDIA graphics processing units (GPUs) to speed up fluid dynamics simulation and quickly handle large, complex simulation models. Available for the first time with ANSYS Fluent 15.0, the jointly developed GPU-accelerated commercial computational fluid dynamics solver broadens support for NVIDIA GPUs across the ANSYS simulation portfolio, building upon the previous success with GPU support in ANSYS Mechanical.
Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. Researchers from the University of Washington and the German Space Agency (DLR) measured the dramatic speeds of the fast-flowing glacier in 2012 and 2013. The results are published January 31, 2014, in The Cryosphere, an open access journal of the European Geosciences Union (EGU).
Water resource management involves numerous and often distinct areas, such as hydrology, engineering, economics, public policy, chemistry, ecology and agriculture, among others. It is a multi-disciplinary field, each with its own set of challenges and, in turn, its own set of computer models.
Prince Charles has called people who deny human-made climate change a "headless chicken brigade" who are ignoring overwhelming scientific evidence. The heir to the British throne, a dedicated environmentalist, accused "powerful groups of deniers" of mounting "a barrage of sheer intimidation" against opponents.
The National Energy Research Scientific Computing (NERSC) Center recently accepted “Edison,” a new flagship supercomputer designed for scientific productivity. Named in honor of American inventor Thomas Alva Edison, the Cray XC30 will be dedicated in a ceremony held at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) on February 5, 2014, and scientists are already reporting results.
Dassault Systèmes, a 3-D design software, 3-D Digital Mock Up and Product Lifecycle Management (PLM) solutions provider, and Accelrys, a provider of scientific innovation lifecycle management software for chemistry, biology and materials, have announced the signing of a definitive merger agreement for Dassault Systèmes to acquire San Diego-based Accelrys, Inc.
Sandia National Laboratories is developing computer models that show how radioactive waste interacts with soil and sediments, shedding light on waste disposal and how to keep contamination away from drinking water. Researchers have studied the geochemistry of contaminants, such as radioactive materials and toxic heavy metals, including lead, arsenic and cadmium. But laboratory testing of soils is difficult.
NASA has created a unique spherical film showing water's journey and extensive impact as it cycles through Earth. "Water Falls" will premiere this month on spherical movie screens at special events hosted by The Wild Center in Tupper Lake, NY, and The Space Foundation in Colorado Springs, CO. Shortly afterwards, it will be released to more than 100 Science On a Sphere venues worldwide, starting January 31, 2014.
The New Madrid fault zone in the nation's midsection is active and could spawn future large earthquakes, scientists reported January 23. 2014. It's "not dead yet," said U.S. Geological Survey seismologist Susan Hough, who was part of the study published online by the journal Science.
Momentum 3.3 automation scheduling software offers features to facilitate set-up and streamline workflows. It incorporates graphical system layout and an instrument integration suite within the runtime environment.
This month, the Texas Advanced Computer Center (TACC) at The University of Texas at Austin, US, along with technology partners HP and NVIDIA, will deploy Maverick — a powerful, high-performance visualization and data analytics resource for the open science and engineering community.
Outshining the black holes they surround, the bright, hot centers of galaxies known as active galactic nuclei can spew jets of plasma thousands of light-years long. These streams of plasma create an effect often seen in popular images — galaxies speared through the heart by intense light. Such jets are also associated with stars and other astronomical phenomenon.
Metamaterials are artificial materials engineered to have properties that are not normally found in nature. Typical examples include cloaking materials that can render a person or an aircraft completely invisible to detection. In addition, metamaterials are being explored in a number of cutting-edge technologies including perfect lenses, antennas and terahertz devices.
Software Review: Unscrambler statistical software is geared to two of the most useful areas of industrial R&D, namely multivariate analysis and experimental design.

eQUEUE is designed to be an intuitive Web-based front-end job submission tool and management portal that increases cluster utilization by making it easier to run jobs from any Web browser. It has the added value of virtually eliminating errors through pre-defined job submission scripts.
New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe.
If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body. Supported by National Institutes of Health grants, researchers discovered a molecular "switch" in a receptor that controls cell behavior using a supercomputer.
During particularly intense solar storms the magnetosphere can “crack,” allowing charged particles to seep in and wreak havoc on the Earth’s technological infrastructure — an event called space weather. Scientists currently do not have the ability to accurately predict the severity of a space weather event or where it will have the most impact. But researchers are hoping to change that.
Scientists want to manipulate cell behavior for a lot of reasons. If they can control cell functions, such as movement and development, they can cripple cells and pathogens that are causing disease in the body. Using computational molecular dynamics simulations, researchers have discovered a molecular “switch” in a receptor that controls cell behavior.
