Certain primordial stars — those between 55,000 and 56,000 times the mass of our Sun, or solar masses — may have died unusually. In death, these objects — among the Universe’s first-generation of stars — would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
By combining a pair of solar cells made with a mineral called perovskite and low cost...
A researcher proposes to construct a new quantum computer, able to perform multiple operations...
The Soyuz TMA-14M rocket is launched with Expedition 41 Soyuz Commander Alexander Samokutyaev of the Russian Federal Space Agency (Roscosmos) Flight Engineer Elena Serova of Roscosmos, and Flight Engineer Barry Wilmore of NASA, Friday, September 26, 2014 at the Baikonur Cosmodrome in Kazakhstan.
Cray Inc. has announced that the Department of Defense (DoD) High Performance Computing Modernization Program (HPCMP) has awarded Cray a $26 million supercomputer contract for a next-generation Cray XC supercomputer and a Cray Sonexion storage system.
Mellanox Technologies a supplier of interconnect solutions for servers and storage systems, has announced that its end-to-end 10 and 40 Gigabit Ethernet interconnect solutions support the recently announced IBTA RoCEv2 specification. The RoCEv2 standard enables routing RDMA traffic across Layer 3 Ethernet networks to address the needs of today’s evolving hyperscale Web 2.0 and cloud deployments.
Researchers have shown that information stored in quantum bits can be exponentially compressed without losing information. The achievement is an important proof of principle, and could be useful for efficient quantum communications and information storage. Compression is vital for modern digital communication. It helps movies to stream quickly over the Internet and millions of telephone calls to bounce off of satellites.
New research by biomedical engineers at the University of Minnesota shows that people who practice yoga and meditation long-term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience. The research could have major implications for treatments of people who are paralyzed or have neurodegenerative diseases.
Electricity and magnetism rule our digital world. Semiconductors process electrical information, while magnetic materials enable long-term data storage. A University of Pittsburgh research team has discovered a way to fuse these two distinct properties in a single material, paving the way for new ultrahigh density storage and computing architectures.
Computationally intensive research in Sweden will soon get a boost from the fastest academic supercomputer in the Nordic countries, to be installed in October 2014 at KTH Royal Institute of Technology. KTH is due to begin using the fastest academic supercomputer of any university in Scandinavia. A Cray XC30 with 1,676 nodes and a memory of 104.7 terabytes will be installed at KTH’s PDC Center for High Performance Computing.
This 40X photo shows the star-shaped algae Micrasterias radiosa. It 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 by Rogelio Moreno Gill.
IBM announced that Caris Life Sciences is using IBM technical computing and storage technology to accelerate the company’s molecular profiling services for cancer patients. The Caris tumor profiling database is one of the largest datasets in the application of advanced molecular profiling technologies to support clinicians in delivering personalized treatment recommendations — or precision oncology.
On September 19, 2014, the Operational Land Imager on the Landsat 8 satellite captured these images of the King fire in Eldorado National Forest. In the false-color image, burned forest appears red; unaffected forests are green; cleared forest is beige; and smoke is blue. As of September 23, the blaze had charred 89,571 acres.
Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, physicists are laying the foundations for future predictions. The shorter the interval between two explosions in the solar atmosphere, the more likely it is that the second flare will be stronger than the first one.
Designers of the ambitious U.S. air traffic control system of the future neglected to take drones into account, raising questions about whether it can handle the escalating demand for the unmanned aircraft and predicted congestion in the sky.
With President Obama announcing climate-support initiatives at the 2014 United Nations Climate Summit, the U.S. Department of Energy national laboratories are teaming with academia and the private sector to develop the most advanced climate and Earth system computer model yet created. For Los Alamos National Laboratory researchers, it is a welcome advance for an already vibrant high-performance computing community.
Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth’s water is key to understanding how life-fostering environments come into being and how likely they are to be found elsewhere. New work has found that much of our Solar System’s water likely originated as ices that formed in interstellar space.
A computer model that accurately predicts how composite materials behave when damaged will make it easier to design lighter, more fuel-efficient aircraft. Innovative computer codes form the basis of a computer model that shows in unprecedented detail how an aircraft's composite wing, for instance, would behave if it suffered small-scale damage, such as a bird strike.
