Researchers found a solution to overheating of active plasmonic components. These components will be essential for high-speed data transfer within the optoelectronic microprocessors of the future, which will be able to function tens of thousands of times faster than microprocessors in use today. The researchers have demonstrated how to efficiently cool optoelectronic chips using industry-standard heatsinks despite high heat generation.
A dark solar filament above the sun's surface became unstable and erupted in December 2015, generating a cascade of magnetic arches. A small eruption to the upper right of the filament was likely related to its collapse. The arches of solar material appear to glow as they emit light in extreme ultraviolet wavelengths, highlighting the charged particles spinning along magnetic field lines. A video was taken in extreme UV wavelengths.
Researchers have used an open-source graphics processor unit (GPU) for research. Nyami, a synthesizable GPU architectural model for general-purpose and graphics-specific workloads marks the first time a team has taken an open-source GPU design and run a series of experiments on it to see how different hardware and software configurations would affect the circuit's performance.
Resesrchers developed an unmanned aerial vehicle, named the Fireproof Aerial RObot System, which detects fires in skyscrapers, searches the inside of the building, and transfers data in real time from fire scenes to the ground station. The fireproof FAROS, whose movements rely on a quadrotor system, can also fly and climb walls.
Billions of people use the Internet, which requires huge data centers and results in an enormous energy consumption. In her doctoral dissertation at Umeå University, Mina Sedaghat has developed techniques and algorithms to manage and schedule the resources in these large data centers at a lesser cost, more efficiently, more reliably and with a lower environmental impact.
Physicist Stephen Hawking has warned that new technologies will likely bring about "new ways things can go wrong" for human survival. When asked how the world will end — "naturally" or whether man would destroy it first — Hawking said that increasingly, most of the threats humanity faces come from progress made in science and technology. They include nuclear war, catastrophic global warming and genetically engineered viruses, he said.
Using strands of nucleic acid, scientists have demonstrated basic computing operations inside a living mammalian cell. The research could lead to an artificial sensing system that could control a cell’s behavior in response to such stimuli as presence of toxins or development of cancer. The research uses DNA strand displacement, a technology widely used outside of cells for design of molecular circuits, motors and sensors
Since the dawn of time, humans have endeavored to unravel the laws governing the physical world around us. Over centuries, we have tried to discover a Theory of Everything. Possible candidates, such as String Theory and Grand Unified Theory, require higher dimensions or higher-dimensional symmetries, for instance 10 dimensions, despite their radical difference from the world we experience. One such symmetry exists in eight dimensions.
Physicists have long predicted the possibility of tying knots in quantum fields. But no one has been able to make or observe a three-dimensional quantum knot, until now. In a breakthrough discovery, a scientific team has found a way to create knotted solitary waves in a quantum-mechanical field. The scientific team created the quantum knots, also known as knot solitons, at Amherst College.
Grid Modernization: Working to Keep the Nation’s Increasingly Interconnected Electric Power Grid SecureJanuary 19, 2016 10:56 am | by Sandia National Laboratories | News | Comments
Sandia National Laboratories is leading the Security and Resilience area of the DOE's Grid Modernization Laboratory Consortium (GMLC) and bringing its strong research capability in grid modernization to help the nation modernize its power grid. The consortium includes scientists and engineers from across 14 DOE national labs and dozens of industry, academic and state and local government partners, aligned into six technical areas.
As South West Western Australia residents count the cost of last week’s devastating bushfires, scientists are working on a model to help predict future threats. The work’s aim is to inform preparation and help assess the risks of catastrophes, such as the Yarloop tragedy in which two elderly men died and 143 properties were razed. To develop the models, they are drawing on the Weather Research and Forecast Model, developed in America.
NASA's Juno mission to Jupiter has broken the record to become humanity's most distant solar-powered emissary. The milestone occurred at 11 a.m. PST on January 13, 2016, when Juno was about 493 million miles from the sun. The previous record-holder was the Rosetta spacecraft, whose orbit peaked out at the 492-million-mile mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko.
This 40X photograph shows developing sea mullet embryos. It was the 12th place winner in the 2015 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope and was taken using brightfield microscopy.
Having reviewed several volumes in this series before, it was a delightful surprise to see one in physiology, the area of my doctoral studies. As a quick background, the series deals with many areas of mathematics and the basic sciences cast in the background of Japanese cartoons. Each volume delves into the subject area with interesting plots, amusing zingers, well-moving action and succinct explanations.
Center for Trustworthy Scientific Cyberinfrastructure to provide Cybersecurity Services Tailored to NSF CommunityJanuary 15, 2016 3:03 pm | by Pittsburgh Supercomputing Center | News | Comments
The security of the more than $7 billion in research funded by the National Science Foundation will be significantly bolstered, thanks to a $5-million grant awarded to Indiana University, the National Center for Supercomputing Applications, the Pittsburgh Supercomputing Center and the University of Wisconsin-Madison for a collaborative effort to create the NSF Cybersecurity Center of Excellence. This funding will establish the CTSC.
