The roots of tradition run deep in astronomy. From Galileo and Copernicus to Hubble and Hawking, scientists and philosophers have been pondering mysteries of the universe for centuries, scanning the sky with methods and models that haven’t changed much until the last two decades. Now, a research collaboration of astrophysicists, statisticians and computer scientists is looking to shake things up with a new statistical analysis model.
A team of Chinese physicists has developed a way to confine light. This is significant because the approach allows quantum memories stored within photons to be retained, opening the door to applications in quantum information processing. The results may herald the advent of a multitude of hybrid, optoelectronic devices relying on the use of quantum information stored in photons for processing information.
Researchers have developed a brain prosthesis, designed to help individuals suffering from memory loss, which includes a small array of electrodes implanted into the brain. It is currently being evaluated in human patients. The device builds relies on a new algorithm and builds on more than a decade of collaboration with Sam Deadwyler and Robert Hampson, who have collected the neural data used to construct the models and algorithms.
Cray has been awarded a contract to provide a Cray XC40 to Yukawa Institute for Theoretical Physics (YITP). YITP is renowned for pioneering research in contemporary theoretical physics and named in honor of the first Japanese citizen to win the Nobel Prize. The two-cabinet Cray XC40 system will provide a supercomputer that occupies one-fourth the physical footprint of the previous system and 4x overall performance improvement.
ESA’s Sun-watching Proba-2 satellite experienced three partial solar eclipses on September 13, 2015. On Earth, a single partial eclipse occurred over South Africa, the southern Indian Ocean and Antarctica. During a total solar eclipse, the Moon moves in front of the Sun as seen from Earth, their alignment and separation such that the Moon, situated much closer to Earth, appears large enough to block out light from the more distant Sun.
Alexander Szalay, a Bloomberg Distinguished Professor at the Johns Hopkins University, has been selected as the recipient of the 2015 IEEE Computer Society Sidney Fernbach Award. Szalay was recognized “for his outstanding contributions to the development of data-intensive computing systems and on the application of such systems in many scientific areas including astrophysics, turbulence and genomics.”
First produced in 1940, plutonium is one of the most electronically complicated elements on Earth and, because of its complexities, scientists have been struggling to prove the existence of its magnetic properties ever since. Finally, after more than 70 years, that struggle is over thanks to a timely combination of theory, algorithm and code developments, neutrons experiments, and the second-most-powerful supercomputer in the world.
Proteins sometimes run amuck. All the good stuff they contain can get distorted. Mutations can cause long strands of proteins to curl in on themselves and refuse to break apart. These strands can be extremely toxic and are usually harmful. Developing effective medications to treat these diseases typically involves biochemists in a lengthy and expensive process. A suite of computer programs should speed up the process of drug discovery.
The Grace Hopper Celebration of Women in Computing is the largest gathering of women in computing in the world. This year, 12,000 attendees are expected — a 50 percent increase from last year. The conference, held in Houston, will take place October 14 to 16, 2015, and will feature leading technical speakers, career development sessions, awards, a poster session, a hackathon and the industry’s largest career fair for women in computing.
NVIDIA announced that Microsoft will offer NVIDIA GPU-enabled professional graphics applications and accelerated computing capabilities to customers worldwide through its cloud platform, Microsoft Azure. Deploying the latest version of NVIDIA GRID in its new N-Series virtual machine offering, Azure is the first cloud computing platform to provide NVIDIA GRID 2.0 virtualized graphics for enterprise customers.
D-Wave Systems has entered into a new agreement covering installation of a succession of D-Wave systems at NASA's Ames Research Center in Moffett Field, CA. This agreement supports collaboration among Google, NASA and USRA (Universities Space Research Association) dedicated to studying how quantum computing can advance artificial intelligence and machine learning, as well as the solution of difficult optimization problems.
Automated and human verification for voice-based user authentication systems are vulnerable to voice impersonation attacks. Using a voice-morphing tool, researchers developed a voice impersonation attack to attempt to penetrate automated and human verification systems. A voice can be recorded by being in physical proximity to the speaker, a spam call, mining audiovisual clips online or even compromising servers in the cloud.
When the Rosetta space probe sent back its first close-up pictures of a comet last year, scientists got a bit of a surprise: Instead of the ball of rock and ice they had expected, the comet turned out to have two distinct lobes connected by a "neck." Researchers have now concluded that the comet 67P Churyumov-Gerasimenko was probably formed when two separate objects collided during the early stages of the solar system.
This 25X photograph shows a magnesium chloride and potassium alum mixture. It was designated an Image of Distinction in the 2014 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope and was taken using polarized light.
Soon, it may be easier to design, plan and carry out infrastructure operations in deep water. The EU project called "SWARMs" aims to achieve this by integrating autonomous vehicles such as ROVs and AUVs. Oil and gas production is moving into increasingly deeper waters, offshore wind turbines and wave energy plants are being installed, and minerals on the sea floor are waiting to be exploited, increasing the need for robots.
