The genomes of modern birds tell a story of how they emerged and evolved after the mass extinction that wiped out dinosaurs and almost everything else 66 million years ago. That story is now coming to light, thanks to an ambitious international collaboration that has been underway for four years. The first findings of the Avian Phylogenomics Consortium are being reported nearly simultaneously in 28 papers.
Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo — the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.
Could there finally be tangible evidence for the existence of dark matter in the Universe? After sifting through reams of X-ray data, scientists at EPFL and Leiden University believe they could have identified the signal of a particle of dark matter. This substance, which up to now has been purely hypothetical, is run by none of the standard models of physics other than through the gravitational force.
Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver — say, a computer and a printer — are off by even a single bit relative to each other, communication between them breaks down entirely.
Celebrating its 30th conference anniversary, ISC High Performance has announced that the 2015 program’s technical content “will be strikingly broad in subject matter, differentiated and timely.” Over 2,600 attendees will gather in Frankfurt, from July 12 to 16, to discuss their organizational needs and the industry’s challenges, as well as learn about the latest research, products and solutions.
This 25X photo received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using Nomarski Differential Interference Contrast.
The mystery of where Earth's water came from got murkier on December 10, 2014, when some astronomers essentially eliminated one of the chief suspects: comets. Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind.
The US Department of Energy is mining for solutions to the rare earth problem — but with high-performance computing instead of bulldozers. Researchers are using the hybrid CPU-GPU, 27-petaflop Titan supercomputer managed by the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory to discover alternative materials that can substitute for rare earths.
Springer and Simula have launched a new book series, which aims to provide introductions to select research in computing. The series presents both a state-of-the-art disciplinary overview and raises essential critical questions in the field. All Simula SpringerBriefs on Computing are open access, allowing for faster sharing and wider dissemination of knowledge.
MS affects more than two million people worldwide. Symptoms are different for everyone but commonly include fatigue, tingling, speech problems and difficulties with walking and balance. To gain a better understanding of MS and its treatments, there is a need for a system to collect comprehensive data that provides an in-depth picture of the experiences of MS patients across a large population.
What does a black hole look like up close? As the sci-fi movie Interstellar wows audiences with its computer-generated views of one of most enigmatic and fascinating phenomena in the universe, University of Arizona (UA) astrophysicists Chi-kwan Chan, Dimitrios Psaltis and Feryal Ozel are likely nodding appreciatively and saying something like, "Meh, that looks nice, but check out what we've got."
This 200X photo of a bamboo stem cross section received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using autofluorescence.
An interstellar mystery of why stars form has been solved thanks to the most realistic supercomputer simulations of galaxies yet made. Theoretical astrophysicist Philip Hopkins led research that found that stellar activity — like supernova explosions or even just starlight — plays a big part in the formation of other stars and the growth of galaxies.
Intel demonstrated for the first time with Professor Stephen Hawking a new Intel-created communications platform to replace his decades-old system, dramatically improving his ability to communicate with the world. The customizable platform will be available to research and technology communities by January of next year. It has the potential to become the backbone of a modern, customizable system other researchers and technologists can use.
In a real-time challenge, the 11 teams of undergraduate students will build a small cluster of their own design on the ISC 2015 exhibit floor and race to demonstrate the greatest performance across a series of benchmarks and applications. It all concludes with a ceremony on the main conference keynote stage to award and recognize all student participants in front of thousands of HPC luminaries.
