Inspired by the termites’ resilience and collective intelligence, a team of computer scientists and engineers at Harvard Univ. has created an autonomous robotic construction crew. The system needs no supervisor, no eye in the sky and no communication. Exhibiting a swarm-like intelligence, these robots, in any number, can cooperate simply by modifying their environment.
It's not quite Star Trek communications—yet. But long-distance communications in space may be easier now that researchers have designed a clever detector array that can extract more information than usual from single particles of light. Described in a new paper, the NIST/JPL array-on-a-chip easily identifies the position of the exact detector in a multi-detector system that absorbs an incoming infrared light particle, or photon.
EQUiSat, a nanosatellite being built by a team of Brown Univ. students, has been cleared for launch. NASA announced that EQUiSat is among 16 small satellites selected to fly on rockets to be launched over the three-year period beginning in 2015. EQUiSat has not been assigned to a particular rocket, but the announcement assures that the student-led project has a ticket to ride.
Growing up in a traditional society, Abeer Abu Ghaith was often told a woman's future is in her husband's kitchen. Quietly, the 29-year-old proved everyone wrong. Abu Ghaith has become the first female high-tech entrepreneur in the West Bank, setting up an Internet employment brokerage and software development firm.
Legislation unveiled in California would require smartphones and other mobile devices to have a "kill switch" to render them inoperable if lost or stolen. State Sen. Mark Leno, San Francisco District Attorney George Gascon and other elected and law enforcement officials say the bill, if passed, would require mobile devices sold in or shipped to California to have the anti-theft devices starting next year.
Via social media, researchers at the Federal Polytechnic Institute of Lausanne (EPFL) will be tracking emotions of the viewing public during the Olympic Games in Sochi. Their goal is to show, in real time, what people are feeling during the competitions. The new software will not only contend with multiple languages and breakneck speed, it will also track dozens of commonly used emoticons.
Your car might see a deadly crash coming even if you don't, the government says, indicating it will require automakers to equip new vehicles with technology that lets cars warn each other if they're plunging toward peril. The action, still some years off, has "game-changing potential" to cut collisions, deaths and injuries, federal transportation officials said at a news conference Monday.
Researchers in California have made progress in a project to develop fast-blinking light-emitting diode systems for underwater optical communications. They have shown that an artificial metamaterial can improve the “blink speed” of a fluorescent light-emitting dye molecule 76 times faster than normal while increasing brightness 80-fold.
A new long-range wireless tag detection system, with potential applications in health care, environmental protection and goods tracking, can pinpoint items with near 100% accuracy over a much wider range than current systems. The system, invented in the U.K., improves the performance of passive, battery-less RFID tag detection through the use of a new antenna setup.
Scientists at Ames Laboratory have demonstrated broadband terahertz (THz) wave generation using metamaterials. The discovery may help develop noninvasive imaging and sensing, and make possible THz-speed information communication, processing and storage.
Expectations are high for RoboEarth, a new European-funded system to speed the development of human-serving robots. Scientists from five major European technical universities have gathered in the Netherlands this week for its launch and to demonstrate possible applications. The first: the deceptively simple task of delivering a glass of milk to a patient in a mock-up hospital room.
Computer scientist Yi-Kai Liu at NIST has devised a way to make a security device that has proved notoriously difficult to build: a "one-shot" memory unit, whose contents can be read only a single time. The innovation, which uses qubits and conjugate coding, shows in theory how the laws of quantum physics could allow for the construction of such memory devices.
New research finds that the social benefits of autonomous vehicles will outweigh the likely disadvantages. Decreased crashes, increased mobility, and increases in fuel economy will drive the technology forward, says RAND Corp. researchers, despite privacy concerns and need for updates in insurance regulations.
Researchers at the Massachusetts Institute of Technology have found a way to allow people in one place to interact with 3-D versions of people or objects in a different location. MIT's Tangible Media Group calls the technology inFORM, and it could one day be used by architects, urban planners, or even doctors who need to look at computed tomography scans.
The completion of the 30-day Lunar Laser Communication Demonstration (LLCD) mission has helped confirm laser communication capabilities from a distance of almost 250,000 miles. In addition to demonstrating record-breaking data download and upload speeds to the moon at 622 and 20 Mbps, respectively, LLCD also showed that it could operate as well as any NASA radio system.
After successfully text messaging “O Canada” using evaporated vodka, two researchers in Canada and their UK-based counterpart say their simple system can be used where conventional wireless technology fails. The chemical signal, using the alcohol found in vodka, was sent 4 m across the lab with the aid of a tabletop fan.
Researchers at The Univ. of Texas at Austin have proposed the first design of a cloaking device that uses an external source of energy to significantly broaden its bandwidth of operation. The team has proposed a design for an active cloak that draws energy from a battery, allowing objects to become undetectable to radio sensors over a greater range of frequencies.
Networks of nanometer-scale machines offer exciting potential applications in medicine, industry, environmental protection and defense, but until now there’s been one very small problem: the limited capability of nanoscale antennas fabricated from traditional metallic components. With antennas made from conventional materials like copper, communication between low-power nanomachines would be virtually impossible.
Gaming could become much more realistic with new technology developed at the MIT Computer Science and Artificial Intelligence Lab (CSAIL) that permits highly accurate, 3-D motion tracking. The new system, dubbed “WiTrack”, uses radio signals to track a person through walls and obstructions, pinpointing her 3-D location to within 10 to 20 cm, about the width of an adult hand.
A connected vehicle network, with vehicles exchanging information with the highway infrastructure and other vehicles using wireless communications, could improve traffic safety, mobility and environmental impacts. Southwest Research Institute, which has considerable expertise in intelligent vehicle development, is now serving as an official Connected Vehicle Affiliated Test Bed for this technology.
The information and communications technologies (ICT) industry, and the significant level of R&D that supports it, is driven by constant change in consumer preferences, market demand and technological evolution. The ICT industry is the largest private-sector R&D investor in the U.S., performing nearly one-third of the total.
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived. A team of physicists believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
Researchers in Switzerland have managed to combine antennas and solar cells to work together with unprecedented efficiency in a near future. This is a first step towards more compact and more lightweight satellites. The technology could also be deployed in the autonomous antenna systems used in the aftermath of natural disasters.
