Fewer cords, smaller antennas and quicker video transmission. This may be the result of a new type of microwave circuit that was designed at Chalmers Univ. of Technology. The research team behind the circuits currently holds an attention-grabbing record: 40 Gbps, about twice as fast as the previous record at 140 GHz. The results will be presented at a conference this week in San Diego.
Sensors developed by SmartCardia, a spin-off from EPFL in Switzerland, use various biological vital signs to transmit data to a host of everyday objects. This data, which includes heart rate, respiration activity, skin conductivity and physical exertion, can be used dim a light, control immersive playing on a computer, and track yoga exercises in real time.
A partnership between Rensselaer Polytechnic Institute, IBM, and the FUND for Lake George has developed preliminary models of key natural processes within the watershed. A network of 12 sensor platforms including vertical profilers and tributary monitoring stations are now being deployed in Lake George and its tributaries, providing an unprecedented amount of data for researchers that will be interpreted at a new visualization laboratory.
Computer chips with superconducting circuits would be 50 to 100 times as energy efficient as today’s chips, an attractive trait given the increasing power consumption of the massive data centers that power Internet sites. Superconducting chips also promise greater processing power: Superconducting circuits that use so-called Josephson junctions have been clocked at 770 GHz, or 500 times the speed of the chip in the iPhone 6.
Magnetic materials store the vast majority of the 2.7 zettabytes of data that are currently held worldwide. In the interest of efficiency, scientists have begun to investigate whether magnetic materials can also be used to perform calculations. In a recent paper, researchers in the U.K. detail their plan to harness swirling “tornadoes” of magnetization in nanowires to perform logic functions. They plan to soon build prototypes.
Mark Skwarek has raised over $30,000 on the group fundraising site Kickstarter to launch Semblance Augmented Reality (AR). His company aims to liberate video games from the TV and turn them into physical experiences, such as battling militants in New York’s Central Park. He's poised to release Semblance AR's first app for iOS and Android phones.
Two research teams working in the same laboratories in Australia have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits", which are the building blocks for quantum computers, that each process quantum data with an accuracy above 99%. They represent parallel pathways for building a quantum computer in silicon.
Over the telephone, in jail and online, a new digital bounty is being harvested: the human voice. Businesses and governments around the world increasingly are turning to voice biometrics, or voiceprints, to pay pensions, collect taxes, track criminals and replace passwords. Those companies have helped enter more than 65 million voiceprints into corporate and government databases.
What could the natural diversity and beauty of plant leaves have in common with the violin? Much more than you might imagine. Dan Chitwood of the Donald Danforth Plant Science Center in St. Louis is applying “morphometrics”, which statistically tests hypotheses about factors that affect shape, to changes in the shape of violins over time. His work revealed a strong degree of design transmission and imitation.
IBM revealed details about new projects for its Watson cognitive computing software as it opened its New York headquarters. The company has been developing business uses for Watson with clients since it announced in January it was investing more than $1 billion in the technology, including about $100 million in startup companies working on Watson projects.
Scientists at EPFL in Switzerland have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor devices.
Until now, researchers searching for compounds that have the potential to become a new HIV drug have been hampered by slow computers and inaccurate prediction models. Now, researchers in Denmark have developed an effective model based on quantum mechanics and molecular mechanics that has found, out of a half-million compounds, 14 of interest in just weeks.
People who wish to know how memory works are forced to take a glimpse into the brain. They can now do so without bloodshed: Researchers have developed a new method for creating 3-D models of memory-relevant brain structures. The approach is unique because it enables automatic calculation of the neural interconnections in the brain on the basis of their position inside the space and their projection directions.
Trying on clothes when a shop is closed could become a reality thanks to new research that uses semi-transparent mirrors in interactive systems. The innovation, which builds on a mirror’s ability to map a reflection to one unique point behind the mirror, independently of the observer’s location, could change the way people interact and collaborate in public spaces, such as museums and shop windows.
The world’s fiber-optic network spans more than 550,000 miles of undersea cable that transmits Email, Websites and other packets of data between continents, all at the speed of light. A rip or tangle in any part of this network can significantly slow telecommunications around the world. Now, engineers have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface.
The National Institute of Standards and Technology (NIST) has published its NIST Framework and Roadmap for Smart Grid Interoperability Standards, Release 3.0, a document that reflects advances in smart grid technologies and developments from NIST’s collaborative work with industry stakeholders. Revisions to its guidelines for smart grid cybersecurity are available as well.
A rip or tangle in any part of world’s 550,000-mile fiber-optic network can significantly slow telecommunications around the world. Now engineers have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The research combined laboratory experiments with custom-designed cables, computer-graphics technology used to animate hair in movies, and theoretical analyses.
It's a tough challenge for the National Football League to entice fans off their comfy couches and into stadiums when ticket prices are almost as high as the sport's TV ratings. Equipped with lots of technology, fans at home can watch multiple games on Sunday from the couch. So when the owners of the San Francisco 49ers drew up plans for the team's new $1.3 billion stadium, they tapped the ingenuity surrounding their Silicon Valley home.
Scientists have created a new map of the world's seafloor, offering a more vivid picture of the structures that make up the deepest, least-explored parts of the ocean. The feat was accomplished by accessing two untapped streams of satellite data, which has allowed thousands of previously uncharted mountains rising from the seafloor, called seamounts, to be revealed on the map, along with new clues about the formation of the continents.
Commercial devices capable of encrypting information in unbreakable codes exist today, thanks to recent quantum optics advances, especially the generation of photon pairs. Now, an international team is introducing a new method to achieve a different type of photon pair source that fits into the tiny space of a computer chip. The team’s method generates “mixed up” photon pairs from devices that are less than one square millimeter in area.
More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage of birds. Though many were skeptical of Darwin's "jump dispersal" idea and instead supported the idea of the use of land bridges, a new computational method now suggests that Darwin might have been correct.
Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A study by researchers from the Univ. of Illinois at Urbana-Champaign has shown that standard thermal models will lead to the wrong answer in a 3-D heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.
Researchers in the Netherlands can now, for the first time, remotely control a miniature light source at timescales of 200 trillionths of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.
Only a minority of suspicious mammograms actually leads to a cancer diagnosis, which results in lots of needless worry and spent time for women and their families. Ultrasound elastography could be an excellent screening tool but it requires a lot of skill and interpretation. In an effort to improve results, researchers in Michigan have developed a virtual “breast”, allowing medical professionals to practice in the laboratory.
Electrical engineers in Germany have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on 3-D arrangements of nanometer-scale magnets instead of transistors. In a 3-D stack of nanomagnets, the researchers have implemented a so-called “majority” logic gate, which could serve as a programmable switch in a digital circuit.
