Plans for the construction of the world's largest digital camera at the SLAC National Accelerator Laboratory have reached a major milestone. The 3,200-megapixel centerpiece of the Large Synoptic Survey Telescope, which will provide unprecedented details of the universe and help address some of its biggest mysteries, has received key "Critical Decision 2" approval from the DOE.
For household robots ever to be practical, they’ll need to be able to recognize the objects they’re supposed to manipulate. But while object recognition is a highly studied topic in artificial intelligence, even the best object detectors still fail much of the time. Researchers at MIT believe that household robots should take advantage of their mobility and their relatively static environments to make object recognition easier.
Smartwatches don't have to look ugly to be functional. Clothing and accessories designers are collaborating with engineers to produce computerized wristwatches that people will want to wear all day and night. With Apple Inc. preparing to release a watch line that includes an 18-karat gold edition, rivals know they need to think beyond devices that look like miniature computers.
If you’re sitting in a coffee shop, tapping away on your laptop, feeling safe from hackers because you didn’t connect to the shop’s Wi-Fi, think again. The bad guys may be able to see what you’re doing just by analyzing the low-power electronic signals your laptop emits even when it’s not connected to the Internet. And smartphones may be even more vulnerable to such spying.
It’s not just the football players who have spent a year training. Univ. of Washington seismologists will again be monitoring the ground-shaking cheers of Seahawks fans, this year with a bigger team, better technology and faster response times. Scientists with the Pacific Northwest Seismic Network will install instruments this Thursday to provide real-time monitoring of the stadium’s movement during the 2015 NFL playoffs.
First responders have downloaded more than 10,000 copies of a guide to commercially available, hand-portable biodetection technologies created to help them determine what they might be up against in the field. Since many first responders do not always have immediate access to a computer, a mobile version of the guide is now available for cell phones and tablets.
Outside his career as a noted nanochemist, Lawrence Berkeley National Laboratory (Berkeley Lab) director Paul Alivisatos is an avid photographer. To show off his photos, his preferred device is a Kindle Fire HDX tablet because “the color display is a whole lot better than other tablets,” he says.
A team of researchers has built an array of light detectors sensitive enough to register the arrival of individual light particles, or photons, and mounted them on a silicon optical chip. Such arrays are crucial components of devices that use photons to perform quantum computations.
Scientists at Univ. College London, in collaboration with groups at the Univ. of Bath and the Daresbury Laboratory, have uncovered the mystery of why blue light-emitting diodes (LEDs) are so difficult to make, by revealing the complex properties of their main component—gallium nitride—using sophisticated computer simulations.
Physicists developing a prototype quantum hard drive have improved storage time by a factor of more than 100. The team’s record storage time of six hours is a major step towards a secure worldwide data encryption network based on quantum information, which could be used for banking transactions and personal emails.
The Federal Aviation Administration has issued permits to use drones to monitor crops and photograph properties for sale, marking the first time permission has been granted to companies involved in agriculture and real estate. The exemptions to the current ban on commercial drone flights were granted to Advanced Aviation Solutions in Star, Idaho, for “crop scouting,” and to Douglas Trudeau of Tierra Antigua Realty in Tucson, Arizona.
Industrial drying systems are most commonly used in process industries to remove moisture content from the materials. These systems are designed according to the required moisture removal requirement. The working principle of drying systems is purely based on evaporation of liquids from solids.
Research conducted at Griffith Univ. may lead to greatly improved security of information transfer over the Internet. In a paper published in Nature Communications, physicists from Griffith's Centre for Quantum Dynamics demonstrate the potential for "quantum steering" to be used to enhance data security over long distances, discourage hackers and eavesdroppers and resolve issues of trust with communication devices.
If a hacker got to every smart home in a neighborhood, utility bills would shoot up and brownouts, if not blackouts, would be imminent. It’s a cybersecurity nightmare. And it’s exactly what one Michigan Technological Univ.'s Shiyan Hu is working to prevent. His research focuses on hardware and system security for smart devices, ones with chips embedded that respond to a central controller powered by Wi-Fi.
A team of engineers has developed a new acousto-optic device that can shape and steer beams of light at speeds never before achieved. The new technology will enable better optical devices to be made, such as holographs that can move rapidly in real time.
In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now Massachusetts Institute of Technology spinout Essess is bringing similar “drive-by” innovations to energy efficiency in homes and businesses.
With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades are proving trickier to treat with standard antibiotics. New drugs are desperately needed, but so are ways to maximize the effective lifespan of these drugs. To accomplish that, Duke Univ. researchers used software they developed to predict a constantly evolving infectious bacterium's countermoves to one of these new drugs ahead of time.
In the race to design the world's first universal quantum computer, a special kind of diamond defect called a nitrogen vacancy (NV) center is playing a big role. NV centers consist of a nitrogen atom and a vacant site that together replace two adjacent carbon atoms in diamond crystal. The defects can record or store quantum information and transmit it in the form of light.
Sony appears to have a win-win with "The Interview." Not only did the studio score a moral victory by releasing the film in the face of hacker threats, the movie made at least $15 million from more than 2 million digital rentals and purchases in its first four days.
Sony's "The Interview" has been a hacking target, a punchline and a political lightning rod. Now, with its release online at the same time it debuts in theaters, it has a new role: a test for a new kind of movie release.
An hours-long Internet outage Tuesday in one of the world's least-wired countries was probably more inconvenient to foreigners than to North Korean residents, most of whom have never gone online. Even for wired Koreans south of the heavily armed border separating the rivals, the temporary outage made little difference - southerners are banned by law from accessing North Korean websites.
Stanford computer scientists have extended two popular web browsers to make surfing safer while also empowering web developers to deliver creative new services.
Researchers from the University of Southampton have revealed a breakthrough in optical fiber communications. Academics have collaborated to develop an approach that enables direct modulation of laser currents to be used to generate highly advanced modulation format signals.
Cars that run on natural gas are touted as efficient and environmentally friendly, but getting enough gas onboard to make them practical is a hurdle. A new study led by researchers at Rice University promises to help.
