Intelligent Light, in collaboration with scalable solver developers at Georgia Tech and HPC experts at Lawrence Berkeley National Laboratory, has announced that it is achieving breakthrough CFD scalability running the AVF-Leslie combustion simulation code on up to 64,000 cores on supercomputers at the Department of Energy’s National Energy Research Scientific Computing Center.
This 125x photo shows a transverse section of beach oak (Casuarina equisetifolia) twigs with scale leaves. It received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. The photograph was taken using brightfield and image stacking techniques.
Here they are — the top most-visited stories from the past week. A 10-engine battery-powered plane that can take off like a helicopter, fascinating facts about USB OTG, a flexible computing prototype for electronic skin, a detailed look at the "Prostate Cancer Jungle," free Windows 10 upgrades, and an experiment that proves reality does not exist — at least until it is measured — are all among the top hits.
New York Scientific Data Summit is a no-fee annual meeting that aims to accelerate data-driven discovery and innovation by bringing together researchers, developers and end-users from academia, industry, utilities and state and federal governments. Jointly organized by Brookhaven National Laboratory, Stony Brook University and New York University, this year’s conference will take place from August 2 to 5, 2015, at NYU.
Irwin Rose, a biochemist who shared the 2004 Nobel Prize in chemistry for discovering a way that cells destroy unwanted proteins — the basis for developing new therapies for diseases such as cervical cancer and cystic fibrosis — has died. He was 88. He had a "formidable intellect and unwavering curiosity about fundamental biological and chemical processes that are the foundation for life."
There's a chaotic dance going on at the far end of our solar system, involving Pluto and five of its closest friends, a new study finds. Hubble Space Telescope images of Pluto, its largest moon Charon, and tinier moons Styx, Nix, Hydra and Kerberos show the odd rhythmic gyrations of the six distant objects in a dance unlike anything in our solar system. What makes it so odd is that there's a double set of dances going on.
North Korean space agency officials say the country is developing a more advanced Earth observation satellite and are defending their right to conduct rocket launches whenever they see fit, despite protests that the launches are aimed primarily at honing military technologies. The North launched its first and only satellite in 2012. The claim it is working on another comes amid a flurry of attention to its fledgling space agency.
Global warming has not stopped or even slowed in the past 18 years, according to a new federal study that rebuts doubters who've claimed that that heating trends have paused. Scientists at NOAA readjusted thousands of weather data points to account for different measuring techniques through the decades. Their calculations show that, since 1998, the rate of warming is about the same as it has been since 1950.
For the past several years, scientists at Berkeley Lab have been planning the construction of and developing technologies for a very special instrument that will create the most extensive three-dimensional map of the universe to date. Called DESI for Dark Energy Spectroscopic Instrument, this project will trace the growth history of the universe. Unprecedented in its size and scope, it will allow scientists to test dark energy theories.
Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The advance runs counter to many thinning and retreating glaciers nearby in Alaska and around the world. This image shows the glacier on July 22, 2014. Twice in the past hundred years, the moraine has made contact with Gilbert Point and blocked the entrance to Russell Fjord, causing the water level to rise rapidly
As the current Ebola outbreak wanes, scientists have to make the most of every opportunity to prepare for future outbreaks. One such opportunity involves the identification of a safe and effective Ebola vaccine. Supercomputers have aided researchers in modeling which types of clinical trials will provide the best information. They found that changing the study design would lead to better information about the effectiveness of the vaccine.
Type Ia supernovae are famous for their consistency. Ironically, new observations suggest that their origins may not be uniform at all. Using a “roadmap” of theoretical calculations and supercomputer simulations, astronomers observed for the first time a flash of light caused by a supernova slamming into a nearby star, allowing them to determine the stellar system from which the supernova was born.
On June 3, 2015, CERN’s Large Hadron Collider started delivering physics data for the first time in 27 months. After an almost two-year shutdown and several months re-commissioning, the LHC is now providing collisions to all of its experiments at the unprecedented energy of 13 TeV, almost double the collision energy of its first run. This marks the start of season 2. The LHC will now run round the clock for the next three years.
Decentralized partially observable Markov decision processes are a way to model autonomous robots’ behavior in circumstances where neither their communication with each other nor their judgments about the outside world are perfect. The problem is that they’re as complicated as their name. They provide the most rigorous mathematical models of multiagent systems — not just robots, but any autonomous networked devices — under uncertainty.
This 250x photo of paramecium division received an honorable mention in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. The photograph was taken using differential interference contrast.
