In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?
On August 19, 2014, National Aviation Day, a lot of people reflected on how far aviation has...
The first thousand-robot flash mob has assembled at Harvard University. Instead of one highly-...
A photo is worth a thousand words, but what if the image could also represent thousands of other images? New software seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can give users the photographic gist of a kid on Santa’s lap or housecats. It works by generating an image that literally averages the key features of the other photos.

His talk was given at the 248th National Meeting & Exposition of the American Chemical Society (ACS).
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach. The group discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. The new technique gives scientists a way of controlling things adrift on water in a way that resembles sci-fi tractor beams.
No longer just fantastical fodder for sci-fi buffs, cyborg technology is bringing us tangible progress toward real-life electronic skin, prosthetics and ultraflexible circuits.

NASA technologists have hurdled a number of significant challenges in their quest to improve a revolutionary observing technology originally created for the James Webb Space Telescope. This image shows a close-up view of the next-generation microshutter arrays — designed to accommodate the needs of future observatories — during the fabrication process.
A team of engineers used little more than paper and Shrinky dinks — the classic children's toy that shrinks when heated — to build a robot that assembles itself into a complex shape in four minutes flat, and crawls away without any human intervention. The advancedemonstrates the potential to quickly and cheaply build sophisticated machines that interact with the environment.
Turning what seemed like a science fiction tale into reality, an unmanned probe swung alongside a comet on august 6, 2014, after a 4-billion mile (6.4-billion kilometer) chase through outer space over the course of a decade. Europe's Rosetta probe will orbit and study the giant ball of dust and ice as it hurtles toward the sun and, if all goes according to plan, drop a lander onto the comet in the coming months.
As our lives and businesses become ever more intertwined with the Internet and networked technologies, it is crucial to continue to develop and improve cybersecurity measures to keep our data, devices and critical systems safe, secure, private and accessible.

The Columbia River basin in the Pacific Northwest offers great potential for water power; hydroelectric power stations there generate over 20 000 megawatts already. Now a simulation model will help optimize the operation of the extensive dam system.
The magnets cluttering the face of your refrigerator may one day be used as cooling agents, according to a new theory. The theory describes the motion of magnons — quasi-particles in magnets that are collective rotations of magnetic moments, or “spins.” In addition to the magnetic moments, magnons also conduct heat; researchers found that when exposed to a magnetic field gradient, magnons may be driven to move from one end of a magnet to...
NASA's Opportunity Mars rover, which landed on the Red Planet in 2004, now holds the off-Earth roving distance record after accruing 25 miles of driving. The previous record was held by the Soviet Union's Lunokhod 2 rover. If the rover can continue to operate the distance of a marathon — 26.2 miles — it will approach the next major investigation site mission scientists have dubbed "Marathon Valley."
A new method of building materials using light could one day enable technologies that are often considered the realm of science fiction, such as invisibility cloaks and cloaking devices. Although cloaked starships won't be a reality for quite some time, the technique researchers have developed for constructing materials with building blocks a few billionths of a meter across can be used to control the way light flies through them.
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.
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.
