Online retailer Amazon.com aiming to deliver packages quicker than pizza. Its so-called Prime Air unmanned aircraft project, now underway in Amazon’s research and development labs, could get goods to customers in 30 minutes or less. But the company admits it will take years to advance the needed technology and for the needed federal Aviation Administration rules and regulations to be created.
The Chinese government has declared victory in cleaning up what it considers rumors, negativity and unruliness from online discourse, while critics say the moves have suppressed criticism of the government and ruling Communist Party. Beijing launched the campaign this summer, arresting dozens of people for spreading rumors and creating new penalties for people who post libelous information.
While business operations have matured to help better commercialize new products, an important puzzle piece is missing. Companies must fill this gap to complete the big picture and accelerate innovation. That missing piece is science. Over the past few decades, process manufacturing industries adapted business operations to effectively manage transformational changes.
Lidar rangefinders gauge depth by emitting short bursts of laser light and measuring the time it takes for reflected photons to arrive back and be detected. In Science, researchers from Massachusetts Institute of Technology’s Research Laboratory of Electronics describe a new lidar-like system that can gauge depth when only a single photon is detected from each location.
In a new effort to understand magnetism, a group of Hamburg Centre for Ultrafast Imaging researchers created “mimic” magnets by controlling quantum matter waves made of rubidium atoms. Under well-defined conditions made possible with the help of supercomputers, these artificially created magnets can be studied with clarity and then give a fresh perspective on long-standing riddles.
Einstein@Home creates a global supercomputer by connecting more than 350,000 participants that contribute to a variety of scientific projects, particularly astronomy, by conducting distributed analysis routines with their home computers. This resource has already found several pulsars hidden in radio telescope data. Now, “citizen scientists” have helped researchers discover four new gamma-ray pulsars.
The research team was inspired by biological processes in species such as amphibians, which can regenerate severed limbs, engineers in Pittsburgh have developed computational models to design a new polymer gel that would enable complex materials to regenerate bulk sections of severed material using nanorods.
Where do you go to look at the stars? Away from city lights, certainly. But if you're serious about peering far out into space, to the observable edges of our universe, at submillimeter wavelengths, you have to do a little better than that. You have to go farther and higher, up to where the atmosphere is thin. And if you want to look at the stars for more than a few nights a year, you also need some place that is very, very dry.
Suggesting that quantum computers might benefit from losing some data, physicists at NIST have entangled—linked the quantum properties of—two ions by leaking judiciously chosen information to the environment. The NIST experiments used two beryllium ions as quantum bits (qubits) to store quantum information and two partner magnesium ions, which were cooled with three ultraviolet laser beams to release heat.
The Q-factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, and this has so far been limited by coupling the device to a physical contact for support. Researchers in Spain, however, have used optically levitated objects that do not suffer from clamping forces to achieve the highest force sensitivity ever observed with a nanomechanical resonator.
Los Alamos National Laboratory scientists have advanced a magnetic resonance imaging (MRI) technology that may provide a breakthrough for screening liquids at airport security. They’ve added low-power x-ray data to the mix, and as a result have unlocked a new detection technology.
A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds. Appearing in the Proceedings of the National Academy of Sciences, the results solve a long-standing debate and reveal how pollution plays into climate warming. The work can also provide a gauge for the accuracy of weather and climate models.
A $500 “nanocamera” that can operate at the speed of light has been developed by researchers in the Massachusetts Institute of Technology Media Lab. The 3-D camera could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming.
Spontaneous bursts of light from a solid block illuminate the unusual way interacting quantum particles behave when they are driven far from equilibrium. The discovery by Rice Univ. scientists of a way to trigger these flashes may lead to new telecommunications equipment and other devices that transmit signals at picosecond speeds.
Buried under thousands of miles of pavement in California are 27,000 traffic sensors that are supposed to help troubleshoot both daily commutes and long-term maintenance needs on some of the nation's most heavily used and congested roadways. About 9,000 of them do not work, despite their critical role in an "intelligent transportation" system designed to do things like detect the congestion that quickly builds after an accident.
According to recent Princeton Univ.-led research that simulated an emissions-free Earth, the carbon dioxide already in the atmosphere could continue to warm our planet for hundreds of years, even if emission came to a sudden halt. The study suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.
Researchers are trying to plant a digital seed for artificial intelligence by letting a massive computer system browse millions of pictures and decide for itself what they all mean. The system at Carnegie Mellon Univ. is called NEIL, short for Never Ending Image Learning. In mid-July, it began searching the Internet for images continuously and, in tiny steps, is deciding for itself how those images relate to each other.
The scientist credited with inventing the World Wide Web, Tim Berners-Lee, says a growing tide of surveillance is threatening democracy's future. Lee, a former R&D Magazine Scientist of the Year said Friday that as more people use the Internet and social media to "expose wrongdoing," some governments are feeling threatened.
A single layer of tin atoms could be the world’s first material to conduct electricity with 100% efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from SLAC National Accelerator Laboratory and Stanford Univ.
Orbiting telescopes got the fireworks show of a lifetime last spring when they spotted what is known as a gamma ray burst in a far-off galaxy. It’s not an unusual occurrence, but this one set records. Had it been closer, Earth would have been toast. But because this blast was 3.7 billion light-years away, mankind was spared.
It’s not x-ray vision, but you could call it infrared vision. A Univ. at Buffalo-led research team has developed a technique for “seeing through” a stack of graphene sheets to identify and describe the electronic properties of each individual sheet, even when the sheets are covering each other up.
After working at a software company for four years, Massachusetts Institute of Technology (MIT) alumnus Andrew Dougherty was itching to do something entrepreneurial in the energy industry. Browsing the Website of MIT’s $50K (now $100K) Entrepreneurship Competition, he found an exact match for his interests: an invention by MIT postdoctoral researcher Javier García-Martínez that used nanotechnology to improve the efficiency of oil refining.
A new technique that allows curved surfaces to appear flat to electromagnetic waves has been developed by scientists in England. The discovery could hail a step-change in how antennas are tailored to each platform, which could be useful to a number of industries that rely on high performance antennas for reliable and efficient wireless communications.
Univ. of Michigan researchers are the first to use brain imaging procedures to track the clinical action of pregabalin, a drug known by the brand name Lyrica that is prescribed to patients suffering from fibromyalgia and neuropathic pain. The study suggests role of brain imaging in creating personalized treatment of chronic pain.
In a recent study presented at the Supercomputing Conference SC13 in Denver that may earn them the Gordon Bell Prize, physicists from Germany have simulated the motion of billions of electrons within astrophysical plasma jets and calculated the light they emit. Tracking the movements of nearly a hundred billion particles required the help of a high-performance computer.
