Physicists develop Cooling for Processors of the Future

January 20, 2016 10:01 am | by Moscow Institute of Physics and Technology | News | Comments

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.

Solar Dynamics Observatory Captures Hypnotic Magnetic Cascade

January 19, 2016 4:39 pm | by NASA | News | Comments

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.

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.

Gangnam Style has had 2.5 billion viewers, which results in power consumption of more than 400 GWh. If electricity to serve such a demand is generated by diesel, more than 250,000 tons of CO2 would be produced, equivalent to over 100,000 cars per year. "G

New Techniques, Algorithms facilitate more Energy-efficient Data Centers

January 19, 2016 3:23 pm | by Umeå University | News | Comments

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.

Professor Stephen Hawking said that a disaster on Earth — a "near certainty" in the next 1,000 to 10,000 years — will not spell the end of humanity, because by that time humans are likely to have spread out into space and to other stars. Courtesy of Steph

Hawking: Threats to Human Survival Likely from New Science

January 19, 2016 2:42 pm | by AP | News | Comments

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.

Scientists Demonstrate Basics of Nucleic Acid Computing Inside Cells

January 19, 2016 2:15 pm | by John Toon, Georgia Tech | News | Comments

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

E8 exists in eight dimensions and is the largest symmetry without counterparts in every dimension; it is, therefore, called exceptional.

Stepping beyond 3-D: E8 Symmetry Successfully Constructed

January 19, 2016 1:51 pm | by University of York | News | Comments

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.

Researchers Tie Knots in Quantum Matter

January 19, 2016 11:18 am | by Amherst College | News | Comments

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.

30-year Climate Models Help Predict Future Bushfire Threats

January 19, 2016 10:50 am | by Rob Payne, ScienceNetwork WA | News | Comments

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 Spacecraft Breaks Solar Power Distance Record

January 19, 2016 10:39 am | by NASA | News | Comments

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.
