Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well-characterized protein found in muscle to develop a new picture of how biomolecules transport and store oxygen (O2). In doing so, the team has shown how the process of respiration, which is fundamental in humans and other vertebrates, exploits quantum mechanical effects working on tiny scales.

Theoretical physicists at Saarland University have developed a method that enables quantum computers to be powered up and running stably in just five minutes – something that took six hours to achieve previously. This huge time reduction has been achieved by making use of mathematical models.
HPC Innovation Excellence Award: Culham Centre for Fusion Energy, EPCC at the University of Edinburgh, York Plasma Institute at the University of York, and Lund UniversityJune 23, 2014 5:36 pm | Award Winners
Researchers from CCFE, EPCC and the Universities of York and Lund have made substantial recent optimizations for the well-known plasma turbulence code, GS2. This included a total rewrite of the routines that calculate the response matrices required by the code's implicit algorithm, which has significantly accelerated GS2’s initialization, typically by a factor over 10.
University of Wisconsin Researchers utilized HPC resources in combination with multiple advanced forms of protein structure prediction algorithms and deep sequence data mining to construct a highly plausible capsid model for Rhinovirus-C (~600,000 atoms). The simulation model helps researchers in explaining why the existing pharmaceuticals don’t work on this virus.
Jets resulting from particle collisions, like those taking place at the Large Hadron Collider (LHC) housed at CERN near Geneva, Switzerland, are quite possibly the single most important experimental signatures in high-energy physics. Virtually every final-state, high-energy particle produced will be part of a jet.
ANSYS an engineering simulation software company, announced that it has acquired SpaceClaim, a provider of fast and intuitive 3-D modeling software for engineers.
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter. The finding could lead to new ways to manipulate the interaction of electronics and light, an important tool in modern communications networks and high-speed information processing.
IDC has announced the availability of the first in-depth forecasts for high performance data analysis (HPDA), the fast-growing worldwide market for big data workloads that use high performance computing resources. IDC forecasts that the server market for HPDA will grow rapidly at 23.5 percent compound annual growth rate (CAGR) to reach $2.7 billion in 2018 and the related storage market will expand to about $1.6 billion in the same year
While hybrids and electrics may grab the headlines, the real frontier in fuel economy is the switch to lighter materials. Automakers have been experimenting for decades with lightweighting, as the practice is known, but the effort is gaining urgency with the adoption of tougher fuel efficiency standards. To meet the U.S. government's goal of nearly doubling average fuel economy to 45 mpg by 2025, cars need to lose some serious pounds.
Like a Formula One race car stuck in a traffic jam, HPC hardware performance is frequently hampered by HPC software. This is because some of the most widely used application codes have not been updated for years, if ever, leaving them unable to leverage advances in parallel systems. As hardware power moves toward exascale, the imbalance between hardware and software will only get worse. The problem of updating essential scientific ...
This image from NASA/ESA's Hubble Space Telescope shows galaxy NGC 4485 in the constellation of Canes Venatici (The Hunting Dogs). The galaxy is irregular in shape, but it hasn’t always been so. Part of NGC 4485 has been dragged towards a second galaxy, named NGC 4490 — which lies out of frame to the bottom right of this image.
Scientists may be years away from successfully emulating a human or animal brain for research purposes, but the significant — and perhaps unexpected — ethical challenges such work presents have been outlined in a thought-provoking article in the Journal of Experimental & Theoretical Artificial Intelligence.
The first evidence for massive and abrupt iceberg calving in Antarctica, dating back 19,000 to 9,000 years ago, has now been documented by an international team of geologists and climate scientists. Their findings are based on analysis of new, long deep sea sediment cores extracted from the region...
Dassault Systèmes, a 3-D design software company, has announced the introduction of its newest brand, BIOVIA. The new brand is a combination of Dassault Systèmes’ own activities in BioIntelligence, its collaborative 3DEXPERIENCE technologies, and the life sciences and material sciences applications from the recent acquisition of Accelrys.
Scientists have developed a sophisticated computer modelling simulation to explore how cells of the fruit fly react to changes in the environment. The research is part of an on-going study that is investigating how external environmental factors impact on health and disease. The model shows how cells of the fruit fly communicate with each other during its development.
A recent study into the biomechanics of ants — a common insect that can amazingly lift objects many times heavier than its own body — might unlock one of nature’s little mysteries and, quite possibly, open the door to advancements in robotic engineering. Engineers combined laboratory testing and computational modeling conducted to determine the relationship between mechanical function, structural design and material properties ...
Tropical cyclones worldwide are moving out of the tropics and more toward the poles and generally larger populations, likely because of global warming, a surprising new study finds. Atlantic hurricanes, however, don't follow this trend.
For every thought or behavior, the brain erupts in a riot of activity, as thousands of cells communicate via electrical and chemical signals. Each nerve cell influences others within an intricate, interconnected neural network. And connections between brain cells change over time in response to our environment.
Paradigm 14 is designed to enable effective seismic data processing and imaging, velocity modeling and seismic interpretation. It includes features that cover the entire upstream workflow — from processing and imaging to interpretation and modeling, reservoir characterization, reservoir engineering and drilling, and data management.
A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline, with nothing to stop the entire glacial basin from disappearing into the sea, according to researchers at UC Irvine and NASA. The new study presents multiple lines of evidence — incorporating 40 years of observations — that six massive glaciers in the Amundsen Sea sector “have passed the point of no return,”
Move over, Matrix — astronomers have done you one better. They have created the first realistic virtual universe using a computer simulation called "Illustris." Illustris can recreate 13 billion years of cosmic evolution in a cube 350 million light-years on a side with unprecedented resolution.
The melting of a rather small ice volume on East Antarctica's shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come. This is shown in a study published in Nature Climate Change. The findings are based on computer simulations of the Antarctic ice flow using improved data of the ground profile underneath the ice sheet.
Scientists studying graphene’s properties are using a new mathematical framework to make extremely accurate characterizations of the two-dimensional material’s shape. Graphene, discovered in 2004, is a one-atom-thick sheet of graphite. The mathematical framework being used is known as discrete differential geometry, which is the geometry of two-dimensional interlaced structures called meshes.
Twenty years ago, Philip Platzman and Allen Mills, Jr. at Bell Laboratories proposed that a gamma-ray laser could be made from a Bose-Einstein condensate (BEC) of positronium, the simplest atom made of both matter and antimatter. That was a year before a BEC of any kind of atom was available in any laboratory. Today, BECs have been made of 13 different elements.
