Electron microscope scan of a THz circuit detailing its high-electron-mobility transistors

Getting into the Guinness Book of World Records isn't just about who can eat the most hotdogs or fly a paper airplane the highest. Sometimes it involves technological breakthroughs with huge potential. Guinness has handed DARPA’s Terahertz Electronics program the award for the fastest solid-state amplifier integrated circuit. Developed by Northrop Grumman, the Terahertz Monolithic Integrated Circuit (TMIC) is a ten-stage common-source amplifier that cranks speeds of one terahertz (1012 Hz), or one trillion cycles per second.  Read More

The center of the exhibit is a giant radio tuner from the 1920s

If the 19th and 20th centuries were the Transportation Age, then the 21st century is the Information Age. Like most other ages, it didn't suddenly leap into being with the arrival of the Web or the smartphone – it has a history going back more than 200 years. The Science Museum in London is exploring this history in a new permanent exhibit called "Information Age: Six Networks That Changed Our World," which was recently opened by Queen Elizabeth II when she sent the first tweet by a British monarch.  Read More

Free or inexpensive apps to secure your mobile communications (Image: Shutterstock)

Mobile phone users are becoming more savvy to the potential security risks of standard, unencrypted text messaging and wary of government intrusion into everyday communications. Some consumers require encrypted phone calls for information-sensitive business requirements and others just don't like the idea of others prying into their personal lives. Gizmag takes a look at a sampling of the apps available for iOS and Android (and sometimes desktop) to encrypt mobile communications, both text messaging and phone calls.  Read More

ICEdot's Emergency Trigger clips to your helmet strap or wristband, keeping help within ar...

Two years ago, ICEdot presented the Crash Sensor, an emergency notification device designed to mount to sports helmets. After getting it to market last year, the company found that although its customers liked having the sensor-activated emergency notification, some of them also wanted to have a manual emergency notification. ICEdot has responded with the Emergency Trigger.  Read More

Crystals which contain the information of light after the teleportation (Photo: GAP, Unive...

A successful test in passing information from light into matter – using the teleportation of the quantum state of a photon via optical fiber cable to a receiving crystal located over 25 km (15 mi) away – has been claimed by physicists at the University of Geneva. This test shattered the same team’s previous record and may herald the development of greater, long-distance teleportation techniques and qubit communications and computing capabilities.  Read More

A team of researchers from Stanford University and the University of California, Berkeley, has created prototype radio-on-a-chip communications devices that are powered by ambient radio waves. Comprising receiving and transmitting antennas and a central processor, the completely self-contained ant-sized devices are very cheap to manufacture, don't require batteries to run and could give the "Internet of Things" (IoT) a serious kick start.  Read More

Honda's booth at the ITS World Congress

Honda took the occasion of the 2014 ITS World Congress in Detroit to show off some of the company’s latest accomplishments in the field of intelligent transportation. The technologies on display are part of Honda’s goal of a "collision-free society" and "safety for everyone" through assisted driving systems that protect not only the car’s occupants, but pedestrians, cyclists, and others on the road.  Read More

A human test subject in India has emailed the messages "hola" and "ciao" to three other people in France. Doesn't sound too impressive? Well, in this case the words were composed and interpreted using only the brain ... along with some high-tech help.  Read More

Tel Aviv-based start up Effective Space Solutions claims that its DeOrbiter microsatellites could not only be used to dispose of defunct geosynchronous satellites, but could also rescue a pair of errant Galileo satellites currently trapped in the wrong orbit and put them back into service.  Read More

Vehicle-to-vehicle technology allows cars to communicate with one another – and with their...

Early this year, the US Department of Transportation’s (DoT) National Highway Traffic Safety Administration (NHTSA) announced that it would begin steps to enable vehicle-to-vehicle (V2V) technology, in a bid to prevent accidents. Now, the NHTSA has come one step closer to making V2V a reality.  Read More
