In the early morning hours of Oct. 18, NASA’s Lunar Laser Communication Demonstration made history, transmitting data from lunar orbit to Earth at a rate of 622Mbps. That download rate is more than six times faster than previous state-of-the-art radio systems flown to the moon.
A patent filing shows Samsung Electronics Co. is working on a device it calls sports glasses in a possible response to Google's Internet-connected eyewear. A design patent filing at the Korean Intellectual Property Office shows a Samsung design for smartphone-connected glasses that can display information from the handset.
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.
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.
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.
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.
Although the amount of data that can be stored has increased immensely during the past few decades, it is still difficult to actually store data for a long period of time. A researcher has recently demonstrated a way to store data for extremely long periods, even millions of years, using an etched wafer made of tungsten encapsulated by silicon nitride. The material is resistant to both time and elevated temperatures.
Successful experiments by Chinese scientists have indicated the possibility of the country's netizens getting online through signals sent by lightbulbs (LiFi), instead of WiFi. In a recent experiment at Shanghai's Fudan Univ., four computers under a 1-W LED lightbulb connected to the Internet under the principle that light can be used as a carrier instead of traditional radio frequencies, as in WiFi.
Details have been released by IBM Research on Watson-related cognitive technologies that are expected to help physicians make more informed and accurate decisions faster and to cull new insights from electronic medical records (EMR). The new computing capabilities allow for a more natural interaction between physicians, data and EMRs.
In a record-setting experiment, researchers with the Millilink project in Germany transmitted 100 Gbits/sec of data at a frequency of 237.5 GHz over a distance of 20 m in the laboratory. The scientists applied a photonic method to generate the radio signals at the transmitter. After radio transmission, fully integrated electronic circuits were used in the receiver.
NASA's Jupiter-bound spacecraft hit a snag last week after it flew past Earth to increase its speed to barrel beyond the asteroid belt to Jupiter. The Southwest Research Institute, which leads the mission's science operations, now reports that Juno is out of "safe mode."
When a natural disaster strikes and too many people take to their mobile phones at once, cellular networks easily overload. But a graduate student in Canada has found a way to opportunistically use television and radio channels to transmit cellular signals when systems are pushed beyond capacity.
Researchers at Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory and the Qatar Computing Research Institute have developed new tools that allow people with minimal programming skill to rapidly build cellphone applications that can help with disaster relief.
In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.
A SpaceX rocket launched from the California coast Sunday carrying a Canadian satellite intended to track space weather in what was billed as a test flight. The Falcon 9 rocket lifted off from Vandenberg Air Force Base, about 150 miles northwest of Los Angeles, shortly after 9 a.m. under clear skies.
A group of researchers at Caltech has created the optical equivalent of a tuning fork: a device that can help steady the electrical currents needed to power high-end electronics and stabilize the signals of high-quality lasers. The work marks the first time that such a device has been miniaturized to fit on a chip and may pave the way to improvements in high-speed communications, navigation and remote sensing.
Fiber optics has made communication faster than ever, but the next step involves a quantum leap. In order to improve the security of the transfer of information, scientists are working on how to translate electrical quantum states to optical quantum states in a way that would enable ultrafast, quantum-encrypted communications. A research team has demonstrated the first and arguably most challenging step in the process.
Univ. of Illinois at Urbana-Champaign researchers have developed arrays of tiny nanoantennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum. Other nanoscale antenna systems can't be tuned to a longer light wavelength due to limitations of traditional nanoantenna materials. The team used highly doped semiconductors, grown by molecular beam epitaxy.
Scientists at SLAC National Accelerator Laboratory have found a new method to create coherent beams of twisted light—light that spirals around a central axis as it travels. It has the potential to generate twisted light in shorter pulses, higher intensities and a much wider range of wavelengths, including x-rays, than is currently possible.
Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature. That is the conclusion of a new report by scientists from Lawrence Livermore National Laboratory and six other scientific institutions. The research compares multiple satellite records of atmospheric temperature change with results from a large, multimodel archive of simulations.
Is your cable television on the fritz? One explanation, scientists suspect, may be the weather. The weather in space, that is. Massachusetts Institute of Technology researchers are investigating the effects of space weather on geostationary satellites, which provide much of the world’s access to cable television, Internet services and global communications.
A recent study from the Massachusetts Institute of Technology describing how graphene can be used to convert signals from optical to electrical has also been explored by engineers in Austria, who have also constructed a graphene light detector on a semiconductor chip. According to the researchers, graphene can convert all light wavelengths which are used in telecommunications.
From Sept. 16 to 18, 2013, top leaders from the White House and U.S. science agencies and their international colleagues will gather for three days in Washington, D.C., for a major meeting of the Research Data Alliance (RDA). More than 850 researchers and data experts belong to the RDA, which focuses on the development and adoption of common tools, harmonized standards and infrastructure needed for data sharing by researchers.
A remote region of Kenya that suffers from frequent droughts may soon be flush with water after the discovery of huge underground aquifers. Two aquifers have been identified in the Turkana region of Kenya by using satellite exploration technology. Three other aquifers have been detected but need to be confirmed through drilling.
Poor research data can lead to mistakes in equipment selection, over-design of industrial plant components, difficulty simulating and discovering new processes, and poor regulatory decisions. However, traditional peer review is not enough to ensure data quality amid the recent boom in scientific research findings, according to results of a 10-year collaboration between NIST and five technical journals.
