Using game theory and market dynamices, Harvard University economist Alvin Roth has helped develop a suite of computer programs that match living kidney donors with recipients. The software comprehensively addresses the common limitations of this complicated process, matching participants with compatible blood types and antibodies.
The title of world’s most accurate clock has been transferred from devices based on the steady oscillations of the cesium atom to clocks based on optical transitions. Before this newfound precision can redefine the second, or lead to new applications like ultra-precise navigation, the system used to communicate time around the globe will need an upgrade. Researchers have recently demonstrated how this could be accomplished.
On Tuesday, a team at Switzerland's Federal Institute of Technology in Lausanne used a simple head cap to record the brain signals of Mark-Andre Duc, a partial quadriplegic at a hospital about 100 km away. Duc's thoughts, or electrical signals, were decoded almost instantly by a laptop at the hospital, which then relayed them to a foot-tall robot that scooted around the laboratory.
As cyber attacks worsen and the tactics employed by hackers grow more nefarious, Congress is being asked to consider legislation to improve defenses for government, municipal, and corporate networks. However, the U.S. Chamber of Commerce and other business groups are applying pressure from the other side, saying the rules would cost money without improving risk.
Multi-hop wireless networks can provide data access for large and unconventional spaces, but they have long faced significant limits on the amount of data they can transmit. Now researchers from North Carolina State University have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20% to 80%.
Spectrum rights are the lifeblood of the wireless industry, since they're necessary to operate wireless networks. On Wednesday, Verizon Wireless said it will auction a parcel of radio frequencies potentially worth billions of dollars in an industry scrambling to offer consumers more cellular broadband.
This week at TEDMED 2012, Xerox pulled back the curtain on some of the healthcare-related research occurring in its labs around the world. The company’s innovations include LiveKey, which captures and shares paper-based information in seconds, and predictive clinical analytics solutions enabled by mobile device technology.
Scientists have for decades contemplated communicating via neutrinos when other methods won’t do. For the first time, physicists and engineers at Fermi National Accelerator Laboratory’s MINERvA detector have successfully transmitted a message through 240 m of rock using these ghost-like particles.
Earlier this week, Google gave a glimpse of "Project Glass", an effort to bring the features of a smartphone or tablet computer to a pair of glasses. While wearing a pair, a user can see directions to a destination appear before her eyes, can talk to friends over video chat, can take a photo, or even buy a few things online.
Students in a Purdue University service-learning program have developed an application for Apple's iPad that helps children with severe autism learn how to communicate. The app, called SPEAKall!, allows the children to construct sentences by choosing photos and graphic symbols.
A group of scientists led by researchers from the University of Rochester and North Carolina State University have, for the first time, sent a message using a beam of neutrinos—nearly massless particles that travel at almost the speed of light. The message was sent through 240 m of stone and said simply, "Neutrino."
IBM scientists report on a prototype optical chipset, dubbed Holey Optochip, that is the first parallel optical transceiver to transfer one trillion bits, or one terabit, of information per second, the equivalent of downloading 500 high-definition movies. With the ability to move information at high speeds, the breakthrough could transform how data is accessed, shared, and used for a new era of communications and computing technologies.
A group of Italian and Swedish researchers appears to have solved the problem of radio congestion by cleverly twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received. To demonstrate, they did this in real-life conditions by beaming two corkscrewed radio waves across the waters of Venice, Italy.
Apple was already the world's most valuable company before its market capitalization topped half a billion dollars, a mountain peak where few companies have venture, and few have remained for long. But analysts say Apple’s rally has some legs, because the way it earned its value differs from others who have reached this level, including Exxon and Microsoft.
At the Mobile World Congress in Barcelona Tuesday, Google executive chairman Eric Schmidt predicted that rapid advances in technology will soon transform science fiction into reality—meaning people will have driverless cars, small robots at their command and the ability to experience being in another place without leaving home.
Agilent Technologies Inc. announced that OSAT Company, which specializes in engineering analysis, testing, and inspection techniques, is using Agilent's Electromagnetic Professional software, EMPro, and the Momentum 3D planar electromagnetic simulator to design and simulate new antennas and circuits.
Visible Light Communications (VLC), a University of Edinburgh spin-out, will soon launch its first prototype light-emitting diode communications technology. “Li-Fi” relies on optical spatial modulation and an Internet protocol technology to allow LED light to carry optical wireless communications streams.
Computational sprinting is a new approach to smartphone power and cooling that could give users dramatic, brief bursts of computing capability to improve current applications and make new ones possible. Its developers at the University of Pennsylvania and the University of Michigan are pushing mobile chips beyond their sustainable operating limits, much like a sprinter who runs extremely fast for a relatively short distance.
Researchers have developed a wireless link that bridges two fiber-optic points at an unprecedented 20 billion bits of data per second. The phenomenal speed, which is to be presented at the Optical Fiber Communication Conference and Exposition in Los Angeles next week, was achieved using much higher frequencies than have been typically used in mobile communications.
The International Telecommunication Union, which coordinates global radio spectrum use, recently came to an agreement that provides specific radio frequency bands for ocean radars, which until now operated only on an informal basis and were subject to immediate shut-down if they caused interference with other radio systems. The new technology may eventually make real-time detection of tsunamis and oil spills possible.
At Cebit on March 6, Saarland University Professor Holger Hermanns will present an unusual bicycle. Unlike most other bicycles, his cruiser brakes using a wireless mechanism that theoretically will fail only three times out of one trillion uses. The technology presages what he hopes will be used in the future for train travel.
Until now, web developers have been dealing with multiple third-party programs to display images in a complex way, such as in 3D. The new HTML extension XML3D, to be demonstrated at the Cebit show in Germany in March, will soon allow developers to embed 3D content in an easy way without having to resort of videos or innumerable photographs of various angles.
The smallest transistor ever built—in fact, the smallest transistor that can be built—has been created using a single phosphorous atom by an international team of researchers at the University of New South Wales, Purdue University, and the University of Melbourne.
Discera, a maker of micro-electrical mechanical systems (MEMS)-based timing solutions based in San Jose, Calif., has entered into a distribution deal with Avnet Electronics Marketing Americas, an operating group of Avnet, which distributes computer products, electronic components and embedded technology to customers in over 70 countries.
Imagine if smartphone and tablet users could text a not under the table during a meeting without anyone being the wiser. Mobile gadget users might also be enabled to text while walking, watching TV, or socializing without taking their eyes off what they're doing. Georgia Institute of Technology researchers have built a prototype app for touchscreen mobile devices that is vying to be a complete solution for texting without the need to look at a mobile gadget's screen.
