As left over building blocks of the solar system's formation, asteroids are of significant interest to scientists. Resources, especially water, embedded within asteroids could be of use to astronauts traveling through deep space. Likewise, asteroids could continue to be destinations for robotic and human missions as NASA pioneers deeper into the solar system, to Mars and beyond.

Music fans and critics know that the music of the Beatles underwent a dramatic transformation in just a few years. But, until now, there hasn’t been a scientific way to measure the progression. Computer scientists at Lawrence Technological University have developed an artificial intelligence algorithm that can analyze and compare musical styles, enabling research into their musical progression.
This 100X photo of recrystallized sulfur received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Dr. Edward Leighman Gafford in Richland, WA, using polarized light.
Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision. Chandra, one of NASA's current "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope, is specially designed to detect X-ray emission from hot and energetic regions.
Thanks to NASA's Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside our solar system. The size of the exoplanet, dubbed Kepler-93b, is now known to an uncertainty of just 74 miles (119 kilometers) on either side of the planetary body.
Ensemble forecasting is a key part of weather forecasting. Computers typically run multiple simulations using slightly different initial conditions or assumptions, and then analyze them together to try to improve forecasts. Using Japan’s K computer, researchers have succeeded in running 10,240 parallel simulations of global weather, the largest number ever performed, using data assimilation to reduce the range of uncertainties.
Alan Turing led a team of code breakers at Bletchley Park which cracked the German Enigma machine cypher during WWII but that is far from being his only legacy. In the year of the 100th anniversary of his birth, researchers published a series of ‘Turing tests’ in the Journal of Experimental & Theoretical Artificial Intelligence; these entailed a series of five-minute conversations between human and machine or human and human.
From the Earth-orbiting International Space Station, flying some 225 nautical miles above the Caribbean Sea in the early morning hours of July 15, 2104, NASA astronaut Reid Wiseman photographed this north-looking panorama that includes parts of Cuba, the Bahamas and Florida, and even runs into several other areas in the southeastern US. The long stretch of lights to the left of center frame gives the shape of Miami.
Even within a phylum so full of mean little creatures, the yellow-colored Ormia ochracea fly is distinguished among other arthropods for its cruelty — at least to crickets. Native to the southeastern U.S. states and Central America, the fly is a most predatory sort of parasite. It swoops onto the back of a singing male cricket, deposits a smear of larvae, and leaves its wicked brood to invade, kill and consume the cricket from inside out.
A new home-grown instrument based on bundles of optical fibers is giving Australian astronomers the first 'Google street view' of the cosmos — incredibly detailed views of huge numbers of galaxies. Developed by researchers at the University of Sydney and the Australian Astronomical Observatory, the optical-fiber bundles can sample the light from up to 60 parts of a galaxy, for a dozen galaxies at a time.
NASA doesn't have enough money to get its new, $12 billion rocket system off the ground by the end of 2017 as planned, federal auditors say. The GAO issued a report saying NASA's Space Launch System is at "high risk of missing" its planned initial test flight. The post-space shuttle program would build the biggest rockets ever — larger than the Saturn V rockets which sent men to the moon — to send astronauts to asteroids and Mars.
IBM is making high performance computing more accessible through the cloud for clients grappling with big data and other computationally intensive activities. A new option from SoftLayer will provide industry-standard InfiniBand networking technology to connect SoftLayer bare metal servers. This will enable very high data throughput speeds between systems, allowing companies to move workloads traditionally associated with HPC to the cloud.
This 20X photo of the protozoa Vorticella sp. received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Mr. Frank Fox ofKonz, Rheinland-Pfalz, Germany, using a darkfield technique.
String bends, tapping, vibrato and whammy bars are all techniques that add to the distinctiveness of a lead guitarist's sound, whether it's Clapton, Hendrix, or BB King. Now, guitarist and physicist Dr. David Robert Grimes has described the physics underlying these techniques.
Maybe you’ve sat on the lawn, even hung out on the flightline. Now, for the first time since 1997, NASA Ames Research Center is opening their house. An announcement posted on NASA.gov states: “For our 75th anniversary, we're inviting all of the Bay Area and Silicon Valley to come inside the gates and get to know NASA's center in Silicon Valley. Take a two-mile walking tour through the center and visit with Ames engineers and scientists..."
Interest in magnetic random access memory (MRAM) is escalating, thanks to demand for fast, low-cost, nonvolatile, low-consumption, secure memory devices. MRAM, which relies on manipulating the magnetization of materials for data storage rather than electronic charges, boasts all of these advantages as an emerging technology, but so far it hasn't been able to match flash memory in terms of storage density.
