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.
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.
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.
NASA astronaut Scott Kelly, recently past the halfway mark of his one-year mission to the International Space Station, photographed the Nile River during a nighttime flyover on September 22, 2015.
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,
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.
Here they are — the most visited stories from the past week. A real-life terminator robot; creating mathematical patterns; species that will survive Earth’s sixth mass extinction; the 25th First Annual Ig Nobel Prizes; stunning, crystal-clear images of Pluto; and approval of radar for Nefertiti's tomb quest are all among the top stories.
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.
