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.

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 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.

The photo taken by the Navcam of the Rosetta space probe shows Comet 67P/Churyumov–Gerasimenko. Researchers have now concluded that the comet was probably formed when two separate objects collided during the early stages of the Solar System. (ESA/Rosetta/

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.

Supermassive Black Hole is 30X Expected Size

September 28, 2015 4:30 pm | by Royal Astronomical Society | News | Comments

The central supermassive black hole of a recently discovered galaxy is far larger than should be possible, according to current theories of galactic evolution. New work, carried out by astronomers at Keele University and the University of Central Lancashire, shows that the black hole is much more massive than it should be, compared to the mass of the galaxy around it.

Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. The imaging and topographical information in this process

Liquid Water Flows on Today's Mars

September 28, 2015 4:07 pm | by NASA | News | Comments

New findings from NASA's Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen. These streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons.

Cyber criminals are taking advantage of real-world events with high volumes of traffic on Twitter in order to post links to Web sites containing malware. To combat the threat, computer scientists have created an intelligent system to identify malicious links disguised in shortened URLs on Twitter. The team identified potential attacks within five seconds with up to 83 percent accuracy and within 30 seconds with up to 98 percent accuracy,

Two Human Brains Linked for Direct Brain-to-brain Q&A

September 25, 2015 2:13 pm | by Deborah Bach, University of Washington | News | Comments

Imagine a question-and-answer game played by two people who are not in the same place and not talking to each other. Round after round, one player asks a series of questions and accurately guesses the object the other is thinking about. Sci-fi? Mind-reading superpowers? Not quite. Researchers used a direct brain-to-brain connection to enable participants to play by transmitting signals from one brain to the other over the Internet.

The field of skyrmionics has developed rapidly over the last few years. The very small magnetic vortices could provide a new way to build memory and logical devices with a very low energy use.

Frustrated Magnets Point towards New Memory

September 25, 2015 11:56 am | by University of Groningen | News | Comments

Theoretical physicists have discovered that so-called ‘frustrated magnets’ can produce skyrmions, tiny magnetic vortices that may be used in memory storage. This discovery opens up a new class of materials for scientists working on ‘skyrmionics,’ which aims to build memory and logic devices based on skyrmions.
