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...

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.
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..."
Twisting a screwdriver, removing a bottle cap, and peeling a banana are just a few simple tasks that are tricky to pull off single-handedly. Now, a new wrist-mounted robot can provide a helping hand — or rather, fingers. Researchers at MIT have developed a robot that enhances the grasping motion of the human hand.
A team of Dartmouth scientists and their colleagues have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light — and may play a crucial role in the development of quantum computers, which are predicted to eventually outperform even today’s most powerful supercomputers.
A new material structure developed at MIT generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.
Inspired by science fiction, three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion, computer, navigation equipment, and physical and electrical connections for hardware and sensors for various experiments.
Scientists from Queen Mary University of London have found a successful way of identifying bird sounds from large audio collections, which could be useful for expert and amateur bird-watchers alike. The analysis used recordings of individual birds and of dawn choruses to identify characteristics of bird sounds. It took advantage of large datasets of sound recordings provided by the British Library Sound Archive, and online sources.
The Apollo 11 Lunar Module Eagle, in a landing configuration was photographed in lunar orbit from the Command and Service Module Columbia. Inside the module were Commander Neil A. Armstrong and Lunar Module Pilot Buzz Aldrin. The long rod-like protrusions under the landing pods are lunar surface sensing probes. Upon contact with the lunar surface, the probes sent a signal to the crew to shut down the descent engine.
On July 20, 1969, Buzz Aldrin was "out of town" when the world united and rejoiced in a way never seen before or since. He and Neil Armstrong were on the moon. They missed the whole celebration 45 years ago this Sunday. So did Michael Collins, orbiting solo around the moon in the mother ship.
One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Recent data from the Van Allen Probes — two nearly identical spacecraft that launched in 2012 — address this question.
Over the years, computer chips have gotten smaller, thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore’s Law. But there’s one component of the chip-making process in need of an overhaul if Moore’s law is to continue: the chemical mixture called photoresist.
Dassault Systèmes announced the acquisition of SIMPACK, a multi-body simulation technologies and solutions company. With the acquisition of SIMPACK, based near Munich, Germany, Dassault Systèmes is expanding its SIMULIA realistic multiphysics simulation technology portfolio to include multi-body mechatronic systems, from virtual concept validation to the real-time experience.
With some no bigger than a hummingbird, the hottest things at this week's Farnborough International Airshow are tiny compared with the titans of the sky, such as the Airbus 380 or the Boeing Dreamliner. What's got aviation geeks salivating at Farnborough, this year's biggest aviation jamboree that features participants from 40 countries, are the commercial possibilities of unmanned aerial vehicles — drones to most of us.
The solar panels that Idaho inventor Scott Brusaw has built aren't meant for rooftops. They are meant for roads, driveways, parking lots, bike trails and, eventually, highways. Brusaw, an electrical engineer, says the hexagon-shaped panels can withstand the wear and tear that comes from inclement weather and vehicles, big and small, to generate electricity.
