World's smallest diode made from a single DNA molecule

As electronic devices become ever more complex, and the densities of components in those devices increases exponentially, we are rapidly approaching the day when the limitations of Moore's Law will be realized. In an effort to avert this eventuality, research has concentrated on moving away from traditional silicon technologies and into the realms of molecule-sized components and alternative materials. In this vein, researchers at the University of Georgia (UGA) and Ben-Gurion University in Israel have, for the first time, created a nanoscale electronic diode from a single DNA molecule.

Gravity-measuring smartphone tech might save you from a volcano

Although you may not use a gravimeter to detect tiny changes in gravity (or for anything else), they are commonly used in fields such as oil exploration and environmental surveying. They could have more applications, were it not for the fact that they tend to be relatively large and expensive. Scientists at the University of Glasgow have set about addressing that limitation, by creating a compact gravimeter that incorporates smartphone technology.Read More

Smartphone and laser attachment form cheap rangefinder

A team of researchers at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) led by Li-Shiuan Peh has come up with a new infrared depth-sensing system. The new system, which works outdoors as well as in, was built by attaching a US$10 laser to a smartphone, with MIT saying the inexpensive approach could be used to convert conventional personal vehicles, such as wheelchairs and golf carts, into autonomous ones.Read More

DARPA's latest grand challenge takes on the radio spectrum

One of the most hotly contested bits of real estate today is one you can't see. As we move into an increasingly wireless-connected world, staking out a piece of the crowded electromagnetic spectrum becomes more important. DARPA is hoping to help solve this issue with its latest Grand Challenge, which calls for the use of machine-learning technologies to enable devices to share bandwidth.Read More

Wireless WeKast offers alternative solution to awkward laptop presentations

Whether presenter or presentee, many of us have sustained minutes of stinging silence as human and machine grapple to cooperate. Such is the cliche of pairing laptops with projectors for the purpose of narrating PowerPoint slides in a somewhat restless room. But a new, pocket-sized adapter may replace all those hassles with smart simplicity. The WeKast is designed to be plug and play, instantly casting presentations from a mobile device without the need of Wi-Fi, cables, or a laptop.Read More

Tunable organic electronics pave the way for better flexible displays

Researchers at Kyushu University in Japan have devised a simple way to tweak the properties of organic light-emitting diodes (OLEDs) while increasing emission efficiency eight-fold. The development could lead to organic electronics with stronger performance, that could change their properties in response to external stimuli like pressure.Read More

Review: Sleek Z4 Aurora projector shines bright in some areas, not so much in others

There was a time when watching projection movies and TV meant a huge console in the middle of the living room floor with one red, one blue and one green light throwing pale images onto a nearby screen. Like most tech since then, projectors have gotten smaller and better, rendering super sharp images even from long distances. The Z4 Aurora continues the evolution of the home projector by building in Wi-Fi capability, a music player, gesture control, outstanding speakers and 3D viewing. Some of these features work well, but others clearly need improving, as our tests showed.Read More

SPUD puts a 24-inch display in your back pocket

Sure there are portable monitors you can take along with you to increase the screen real estate of your laptop. You can even use your iPad as a second monitor with an app like Duet. But neither of those options will give you what you're really craving – a take-with-you display that expands to a full-sized monitor so you can get some serious work done when you're on the road. The Spontaneous Pop-Up Display (SPUD) from Arovia, exhibited at this week's South By Southwest Festival (SXSW), will be exactly that.Read More
