A four-story 3-D chip designed at Stanford could help address the current data processing ...

Stanford engineers have pioneered a new design for a scalable 3D computer chip that tightly interconnects logic and memory, with the effect of minimizing data bottlenecks and saving on energy usage. With further work, the advance could be the key to a very substantial jump in performance, efficiency, and the ability to quickly process very large amounts of information  –  known as "Big Data"  –  over conventional chips.  Read More

Denmark’s Aalborg City Business Association is turning to a smart sensor network to monitor and analyze the impact of large-scale events, starting with its Christmas market. Known as BlipTrack, the technology tracks the public’s mobile phones and tablets to provide useful data that can be put to use in easing the flow of urban traffic, optimizing retail setups and more.  Read More

While the stench of rotting food would cause you to stop from chowing down, chances are it became unfit for consumption some time before those funky aromas wafted through your nostrils. Chemists at MIT have been working on a wireless, inexpensive sensor that, among other things, identifies spoiled food early by detecting gases in the air. It then shares its data with a smartphone, potentially alerting users to that soon-to-be moldy fruit in the bottom of the fridge.  Read More

Pizza Hut's eye-tracking Subconscious Menu

Choosing your own pizza toppings from a number of options might seem like a daunting task, but perhaps it isn't as hard as you think ... perhaps your subconscious already knows what you want. That's the thinking behind the new eye-tracking Subconscious Menu, which is being introduced at UK Pizza Huts.  Read More

There are plenty of systems that use an app-running smartphone instead of a key to unlock doors, such as UniKey and Lockitron. A new app not only wants to do that, but wants to give you a seamless journey through buildings. myPORT provides building access, calls elevators and sends intercom feeds to your phone.  Read More

There's another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology's (KIT's) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more efficient and inexpensive than the dominant types of batteries in use today.  Read More

Philips' new 75-watt equivalent SlimStyle LED light bulb

The marketplace for more-or-less normal-looking LED light bulbs became just a little more crowded yesterday, when Philips announced the dimmable 75-watt equivalent version of its SlimStyle bulb. With an output of 1,100 lumens, it's a significant step up from the 60-watt equivalent 800-lumen model that previously sat at the top of the SlimStyle line.  Read More

The LaserWatch displaying the time ... and doing that other thing

Should you ever be captured while checking out a crazed villain's secret headquarters, it's entirely possible that a burning laser might provide you with your only means of escape. Of course, anything that's obviously a laser will be taken from you ... which is why our favorite laser weapons hobbyist, Patrick Priebe, has created a "Bond-inspired LaserWatch."  Read More

Some of the printed circuits, perhaps coming to a milk carton near you

Someday soon, your milk carton may be able to tell you that the milk has spoiled, or your bandage may indicate that it needs changing. These and other things could be made possible by a new technique developed at Singapore's Nanyang Technological University, which allows disposable electronics to be printed on a variety of surfaces, using an existing T-shirt printer.  Read More
