High-performance oscilloscopes, which are capable of measuring signals at very high frequencies, are primarily used in high-speed applications. Agilent Technologies recently released the Infiniium 90000 Q-Series oscilloscope, which is the world’s highest bandwidth commercially available real-time oscilloscope and the first to reach the 60-GHz barrier.
Quantum dots are nano-sized semiconductor particles whose emission color can be tuned by simply changing their dimensions. New research at Los Alamos National Laboratory aims to improve quantum dot-based light-emitting diodes by using a new generation of engineered quantum dots tailored specifically to have reduced wasteful charge-carrier interactions that compete with the production of light.
The modeling and simulation of various manufacturing processes is important because, in many cases, it’s impractical or even impossible to measure the specific operating parameters involved that contribute to the resulting products. This is particularly true in high-temperature processes like blast furnaces or the welding of large metal structures such as those used in shipbuilding and reactor vessels.
The act of walking is seldom given a second thought, but upon closer inspection locomotion is less straightforward. In particular, the ankle is an anatomical jumble, and its role in maintaining stability and motion has not been well characterized. A device called the “Anklebot” could help matters by measuring the stiffness of the ankle in various directions.
At a cosmologically crisp 1 K (-458 F), the Boomerang Nebula is the coldest known object in the Universe—colder, in fact, than the faint afterglow of the Big Bang, which is the natural background temperature of space. Astronomers using the Atacama Large Millimeter/submillimeter Array telescope have taken a new look at this ghostly object to learn more about its frigid properties and to determine its true shape.
Scientists in Germany have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into the world of quantum particles. The new test system will enable the simultaneous study of one hundred light quanta, or photons, and their quantum entanglements. This is a far greater number than was previously possible.
Researchers in The Netherlands have recently unveiled their “photoacoustic mammoscope,” a new device that could someday be used for routine breast cancer screenings. Instead of x-rays, which are used in traditional mammography, the photoacoustic breast mammoscope uses a combination of infrared light and ultrasound to create a 3-D map of the breast.
Over the past three years, 300,000 gamers have helped scientists with genomic research by playing Phylo, an online puzzle game. Now, the McGill Univ. researchers who developed the game are making this crowd of players available to scientists around the globe. The idea is to put human talent to work to improve on what is already being done by computers in the field of comparative genomics.
Semiconductor Research Corporation (SRC) has launched a new research program on hybrid bio-semiconductor systems that they hope will provide insights and opportunities for future information and communication technologies. The Semiconductor Synthetic Biology (SSB) program will initially fund research at six universities.
Researchers in electrical and computer engineering at the Univ. of California, Santa Barbara have introduced and modeled an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene. The demonstration offers possibilities for ultra-energy-efficient, flexible and transparent electronics.
For those wanting to keep their distance from health threats like E. coli-contaminated lettuce or the flu, there are two upcoming apps for that. Pacific Northwest National Laboratory hosted a competition last summer where graduate students used Android development tools and web-based analytics to design mobile apps that could help fight the threats of food-related illnesses and the flu.
A new physics model developed at Rensselaer Polytechnic Institute shows that changing air flows can transfer energy to wind turbines from both above and below the blades. According to the researchers, many wind turbine array studies overlook the fact that important airflow changes occur inside the array.
A new study set out to use numerical simulations to validate previous theoretical predictions describing materials exhibiting so-called antiferromagneting characteristics. A recently discovered theory shows that the ordering temperature depends on two factors—namely the spin-wave velocity and the staggered magnetization. The simulations match these theoretical predictions.
European Union lawmakers on Monday adopted sweeping new data protection rules to strengthen online privacy, and sought to outlaw most data transfers to other countries' authorities to prevent spying. The draft regulation was beefed up after Edward Snowden's leaks about allegedly widespread U.S. online snooping, and the legislation is poised to have significant implications for U.S. Internet companies.
As electronics approach the atomic scale, researchers are increasingly successful at developing atomically thin, virtually 2-D materials that could usher in the next generation of computing. Integrating these materials to create necessary circuits, however, has remained a challenge. Northwestern Univ. researchers have now taken a significant step toward fabricating complex nanoscale electronics.
Two researchers from the Institute for Technology in Architecture in Switzerland have created an immersive space from artificial sandstone with a 3D printer. The design, which cannot be drawn by hand or generated by software such as CAD, resembles a gothic cathedral’s façade and is currently on display in Orléans, France.
We all know to back up our files and photos, but what about our castles and churches? A nonprofit named CyArk has created digital copies of more than 100 of the world's best-known monuments, mapping Roman ruins, ancient statues and even an entire island. Now it plans 400 more, with the goal of preserving the world's most important sites against war, wear and the impact of climate change.
A central topic in spoken-language-systems research is what’s called speaker diarization, or computationally determining how many speakers feature in a recording and which of them speaks when. Speaker diarization would be an essential function of any program that automatically annotated audio or video recordings.
For NASA, data pour in every day like rushing rivers. Spacecraft monitor everything from our home planet to faraway galaxies, beaming back images and information to Earth.
