Here is an agency-by-agency summary of President Barack Obama's proposed budget for fiscal 2015, beginning next Oct. 1. The top-line figures do not include spending on automatic entitlement benefits like Medicare and Social Security. The top-line figures for each agency also omit the $55.4 billion "opportunity" initiative Obama would divide equally between domestic and military programs.
Optical data storage does not require expensive magnetic materials as synthetic alternatives work just as well. This is the finding of an international team from York, Berlin and Nijmegen, published Thursday February 27 in Applied Physics Letters. The team’s discovery brings the much cheaper method...
The 10-day tour of Europe was not your typical itinerary — Garching, Karlsruhe, Villigen, Hamburg and Oxford. In January. But David Brown and Craig Tull of the Computational Research Division and Alex Hexemer of the Advanced Light Source weren’t touring to see the sights — they more interested in seeing the lights — powerful scientific instruments known as light sources that use intense X-rays to study materials
The Department of Energy’s National Energy Research Scientific Computing Center (NERSC) announced the winners of its second annual High Performance Computing (HPC) Achievement Awards on February 4, 2014, during the annual NERSC User Group meeting at Lawrence Berkeley National Laboratory (Berkeley Lab).
An international team of scientists led by physicists from the University of York has paved the way for a new class of magnetic materials and devices with improved performance and power efficiency. Magnetic materials are currently used to store almost all digital information. However, with information processing and storage now making up a significant fraction of the world's energy consumption
Scientists at EPFL have analyzed data from the Large Hadron Collider that offer a first-time observation of an unexpected photon polarization. When emitted in a bottom-quark particle decay, photons behave unlike the predictions of the Standard Model. Elementary particles, like photons, have a...
Man-made global warming is worsening and will disrupt both the natural world and human society, warns a joint report of two of the world's leading scientific organizations. The U.S. National Academy of Sciences and the Royal Society, which is the national scientific academy of the United Kingdom, are releasing an unusual plain language report on climate change that addressed 20 issues in a question-and-answer format.
Our galaxy is looking far more crowded and hospitable. NASA on February 26, 2014, confirmed a bonanza of 715 newly discovered planets outside our solar system. Scientists using the planet-hunting Kepler telescope pushed the number of planets discovered in the galaxy to about 1,700. Twenty years ago, astronomers had not found any planets circling stars other than the ones revolving around our sun.
The Leiden astrophysicist Alexey Boyarsky and his fellow researchers may have identified a trace of dark matter that could signify a new particle: the sterile neutrino. A research group in Harvard reported a very similar signal just a few days earlier.
How do you build a universal quantum computer? Turns out, this question was addressed by theoretical physicists about 15 years ago. The answer was laid out in a research paper and has become known as the DiVincenzo criteria. The prescription is pretty clear at a glance; yet in practice the physical implementation of a full-scale universal quantum computer remains an extraordinary challenge.
Every second, a computer must process billions of computational steps to produce even the simplest outputs. Imagine if every one of those steps could be made just a tiny bit more efficient. researchers have developed a series of novel devices that do just that.
Scientists on the CDF and DZero experiments at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have announced that they have found the final predicted way of creating a top quark, completing a picture of this particle nearly 20 years in the making.
A research collaboration has demonstrated the world's fastest silicon-based device to date. The investigators from IHP-Innovations for High Performance Microelectronics in Germany and the Georgia Institute of Technology operated a silicon-germanium (SiGe) transistor at 798 gigahertz (GHz) fMAX, exceeding the previous speed record for silicon-germanium chips by about 200 GHz.
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.
2014 Rube Goldberg mission: zip a zipper in 20 steps. Chicago-area high school students will showcase a zany assortment of machines that can “Zip a Zipper” in 20 or more steps at this year’s 19th annual Rube Goldberg Machine Contest. The event is sponsored by the U.S. Department of Energy's Argonne National Laboratory and Chicago Children’s Museum.
The scientists and inventors who make big-screen superheroes, spectacular explosions and other only-in-the-movies effects possible have their own Oscar ceremony. Kristen Bell and Michael B. Jordan hosted the film academy's Scientific and Technical Awards February 15, 2014, at the Beverly Hills Hotel, recognizing more than 50 of the most creative scientists and engineers in the movie business.
Scientists say they've taken a key step toward harnessing nuclear fusion as a new way to generate power, an idea that has been pursued for decades. They are still a long way from that goal. The amount of energy they got out of their experimental apparatus was minuscule compared to what they put into it. Still, the new work reached some significant milestones along the path to a cleaner and cheaper source of electricity
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.

Strange events have long been linked to nights of a full moon, though careful scrutiny dispels any association. So, when signals bounced off the lunar surface returned surprisingly faint echoes on full moon nights, scientists sought an explanation in reason rather than superstition. Still, the most compelling evidence arrived during another event that once evoked irrational fears — on a night when Earth's shadow eclipsed the full moon.
A team led by astronomers at The Australian National University has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago. The discovery has allowed astronomers for the first time to study the chemistry of the first stars, giving scientists a clearer idea of what the Universe was like in its infancy.
A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology. Specifically, the team used statistical mechanics and mathematical modeling to shed light on something known as epigenetic memory — how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature.
Seeking a solution to decoherence — the “noise” that prevents quantum processors from functioning properly — scientists have developed a strategy of linking quantum bits together into voting blocks, a strategy that significantly boosts their accuracy. The team found that their method results in at least a five-fold increase in the probability of reaching the correct answer when the processor solves the largest problems
Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope. The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child's top.
The same physics that gives tornadoes their ferocious stability lies at the heart of new University of Washington research, and could lead to a better understanding of nuclear dynamics in studying fission, superconductors and the workings of neutron stars.
