Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and miniaturizing computers.
With the rise of online open course platforms such as Khan Academy, MIT OpenCourseWare and iTunes U, it has never been easier to teach yourself everything from American history to semiconductor manufacturing. These courses enable students to advance at their own pace while accessing the limitless resources...
A new chapter has been opened in our understanding of the chemical activity of nanoparticles says a team of international scientists. Using the X-ray beams of the European Synchrotron ESRF they showed that the electrons absorbed and released by cerium dioxide nanoparticles during chemical reactions behave in a completely different way than previously thought...
Motorola says it wants to equip the world with the latest smartphone technology, at less than a third the price. The new Moto G phone starts at $179 in the U.S. without a contract requirement. That compares with $600 or more that people must pay for phones without traditional two-year service agreements.
Power Integrations announced the HiperTFS-2 family of ICs, combining two-switch-forward and flyback power-supply controller ICs with integrated high-voltage MOSFETs. This high level of integration saves more than 20 components, resulting in a smaller form factor and higher power density.
The Magneto from Farsens S.L., San Sebastián, Spain, is a battery free RFID sensor tag capable of transmitting a unique identifier and the associated magnetic field measurement data to a commercial EPC C1G2 reader without the need of a battery on the sensor tag.
RFMW, Ltd. announces design and sales support for TriQuint’s TGA2567-SM, an AlN packaged, 2-20GHz low noise amplifier (LNA). The TGA2567-SM provides 19dBm P1dB output power with 17dB of small signal gain. Greater than 16dB of adjustable gain can be achieved by varying Vg2.
It could dive deeper than any other submarine, and when it reached the ocean floor, the one-of-a-kind Navy vessel could roll on wheels with lights illuminating the depths outside its windows. The nuclear-powered NR-1, launched in Groton in 1969, was one of the most secretive vessels in the U.S. undersea force.
Ultra-miniature detect switches are playing a significant role in a number of applications today. The miniaturization of key components, including switches, has enabled the continued trend towards end-products getting smaller and smaller.
MtronPTI announced the LF9422 Series L/S Band Filter Diplexer reducing size, weight and power (SWaP) for unmanned vehicle communications. UAVs must operate with a minimum of weight and power yet maintain network-centric communication – command, data and often real-time video – with their ground operators.
What if certain patients could get a bionic pick-up without undergoing the pain and lengthy recovery of surgery? University of Cincinnati researchers are working on just that idea, with the start of an exoskeleton to support people who – through age or injury – are limited in their movement.
Johns Hopkins engineers and cardiology experts have teamed up to develop a fingernail-sized biosensor that could alert doctors when serious brain injury occurs during heart surgery. By doing so, the device could help doctors devise new ways to minimize brain damage or begin treatment more quickly.
SensorData Technologies has announced the global market introduction of the Model M411-106-10K wireless diagnostic system, designed to aid factory floor personnel in the real-time evaluation and predictive maintenance of conveyor systems, with remote data transmission capabilities of up to 750 feet.
Integrated Silicon Solution announced the IS31LT3932, a high performance universal AC input LED Controller for the solid-state lighting (SSL) market place. With a universal input voltage range from 85 to 265VAC, a Power Factor Correction greater than 0.97 and a typical output current accuracy of +/-3%...
American Aerospace Controls (AAC) has announced its complete line of high-reliability standard and custom electrical transducers for rail, heavy locomotive, high-speed train and light rapid transit monitoring. AAC current transducers help rail and locomotive OEMs and their associated design and test engineering personnel to meet stringent EN50155, EN50121 and MIL-STD-202 standards.
The study helps to confirm the idea that the surface of Phobos contains tons of dust, soil, and rock blown off the Martian surface by large projectile impacts. Phobos' orbital path plows through occasional plumes of Martian debris, meaning the tiny moon has been gathering Martian castoffs for millions of years.
Son of Blackbird: Lockheed Martin's Skunk Works has recently revealed its plans for a hypersonic aircraft that will go twice the speed of the SR-71. The SR-72 twin-engine aircraft is expected to travel at Mach 6, with the ability to strike targets. At this speed, no enemy would have time to react or hide.
The next generation of gaming is nearly here, but what about the generation after that one? Sony and Microsoft are launching their new super-powered consoles in the coming weeks. However, gamemakers at last week's Game Developers Conference Next in Los Angeles were already contemplating outside-the-box innovations...
The European Space Agency says one of its research satellites re-entered the Earth's atmosphere early Monday on an orbit that passed over Siberia, the western Pacific Ocean, the eastern Indian Ocean and Antarctica. The 1,100-kilogram (2,425-pound) satellite disintegrated in the atmosphere but about 25 percent of it...
Behlman Electronics has introduced two new power factor corrected AC Power Sources / Frequency Converters. These carry the CE Mark essential for users in member states of the EU and EFTA countries Iceland, Norway, Switzerland and Liechtenstein, plus Turkey.
Microvehicles and other devices that can change shape or move with no power source other than a beam of light may be possible through research led by the University of Pittsburgh. The researchers are investigating polymers that "snap" when triggered by light, thereby converting light energy into mechanical work....
The family of a Silicon Valley engineer who amassed one of the nation's most extensive historic military vehicle collections is giving the tanks, missile launchers and armored vehicles to a Massachusetts-based museum that will preserve and display some of them.
Merit Sensor Systems announced its TR Series temperature-compensated pressure sensor product line. The TR Series packaged pressure sensor features Merit Sensor’s “back-side entry” approach, where the sensing media cannot come in contact with the active, top side of the pressure sensing die.
TT electronics is further extending its range of innovative solutions for challenging applications, with the introduction of three families of thick-film precision resistive dividers targeting high-voltage measurement circuits. The new devices are being launched in response to growing demand in the energy, medical, industrial and instrumentation markets.
OLEDs are already used in the displays of smart phones or digital cameras today. They offer an especially bright image with high contrast, but come with a serious drawback: typically, only one quarter of the electrical energy invested in running the device is actually converted into light.
