Celeste: New Model uses Statistical Inference to Revolutionize Sky Surveys

September 30, 2015 2:20 pm | by Berkeley Lab Computing Sciences | News | Comments

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.

Chinese scientists have uncovered a novel way of stopping light in a state that stores information encoded in photons, opening the door to applications in quantum information processing.

Scientists Uncover New Way of retaining Quantum Memories Stored in Light

September 30, 2015 10:45 am | by Springer | News | Comments

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.

A brain prosthesis builds on research involving electrical signals that travel across regions of the brain’s memory center to provide a breakthrough for people struggling with memory loss.

Scientists Re-encode Memories to Bypass Brain Damage

September 30, 2015 10:23 am | by Robert Perkins, University of Southern California | News | Comments

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.

Sun-watching Satellite Captures Solar Eclipse

September 30, 2015 9:38 am | by ESA | News | Comments

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.

Quantum Mechanical Superposition: Unpuzzling Decades-old Plutonium Perplexities

September 29, 2015 3:12 pm | by Oak Ridge Leadership Computing Facility | News | Comments

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.

Wrangling Proteins Gone Wild: New Software Helps ID Avenues for Improved Treatments

September 29, 2015 2:57 pm | by McGill University | News | Comments

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.

Automated Voice Imitation fools Humans and Machines

September 29, 2015 10:02 am | by Katherine Shonesy, University of Alabama at Birmingham | News | Comments

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.

Rosetta Comet likely formed from Two Separate Objects

September 29, 2015 9:05 am | by Frank Jordans, Associated Press | News | Comments

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.

Robots: Our New Underwater Astronauts

September 28, 2015 4:40 pm | by Sintef | News | Comments

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.
