Promise and peril in an ultra-connected world

March 3, 2014 11:41 am | by Anick Jesdanun, AP Technology Writer | News | Comments

We're in the beginning of a world in which everything is connected to the Internet and with one another, while powerful yet relatively cheap computers analyze all that data for ways to improve lives. At least that's the vision presented this past week at the Mobile World Congress wireless show in Barcelona, Spain, and some of that vision is already available or promised by the end of the year.

Noting tech needs, mining companies seek graphite

February 27, 2014 6:18 am | by Dan Joling - Associated Press - Associated Press | News | Comments

Tear apart an electric car's rechargeable battery and you'll find a mineral normally associated with No. 2 pencils. It's graphite. And experts say the promise of expanded uses for "pencil lead" in lithium-ion batteries, as well as a decrease in supply from China, has helped touch off the largest wave of mining projects in decades.

Want your computer to go faster? Just add light

February 25, 2014 1:26 pm | by Angela Herring, Northeastern Univ. | News | Comments

Last year, a physicist and a mechanical engineer at Northeastern Univ. com­bined their expertise to integrate electronic and optical properties on a single electronic chip, enabling them to switch electrically using light alone. Now, they have built three new devices that implement this fast technology: an AND-gate, an OR-gate and a camera-like sensor made of 250,000 miniature devices.

Want your computer to go faster? Just add light

February 25, 2014 1:14 pm | by Angela Herring, Northeastern Univ. | News | Comments

Every second, your com­puter must process bil­lions of com­pu­ta­tional steps to pro­duce even the sim­plest out­puts. Imagine if every one of those steps could be made just a tiny bit more effi­cient. A Northeastern Univ. team has devel­oped a series of novel devices that do just that. The team combined their expertise to unearth a phys­ical phe­nom­enon that could usher in a new wave of highly efficient electronics.

On the road to Mottronics

February 25, 2014 8:38 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

Mottronics is a term seemingly destined to become familiar to aficionados of electronic gadgets. Named for the Nobel laureate Nevill Francis Mott, Mottronics involve materials that can be induced to transition between electrically conductive and insulating phases. If these phase transitions can be controlled, Mott materials hold promise for future transistors and memories that feature higher energy efficiencies and faster switching speeds.

Phone makers look to emerging markets for growth

February 25, 2014 8:08 am | by Anick Jesdanun - AP Technology Writer - Associated Press | News | Comments

Here's the rub for companies: A good part of the key markets they serve already own smartphones and use them to connect various Internet services. How do you grow from there? Companies from Facebook to Firefox are looking to emerging markets for the next few billion people. They are not only targeting the obvious high-population countries...

Building artificial cells will be a noisy business

February 24, 2014 8:09 am | by Cynthia Eller, California Institute of Technology | News | Comments

Engineers like to make things that work. And if one wants to make something work using nanoscale components, the size of proteins, antibodies and viruses, mimicking the behavior of cells is a good place to start since cells carry an enormous amount of information in a very tiny packet.

Vibration energy the secret to self-powered electronics

February 21, 2014 7:24 am | News | Comments

A multi-university team of engineers has developed what could be a promising solution for charging smartphone batteries on the go, without the need for an electrical cord. Incorporated directly into a cell phone housing, the team's nanogenerator could harvest and convert vibration energy from a surface, such as the passenger seat of a moving vehicle, into power for the phone.

NIST atomtronic study may pave the way for new devices

February 20, 2014 9:04 am | News | Comments

While pursuing the goal of turning a cloud of ultracold atoms into a completely new kind of circuit element, physicists at NIST have demonstrated that such a cloud, known as a Bose-Einstein condensate, can display a sort of "memory." The findings pave the way for a host of novel devices based on "atomtronics," an emerging field that offers an alternative to conventional electronics.

A stretchable highway for light

February 20, 2014 2:53 am | News | Comments

A team of Belgian researchers have made what may be the first optical circuit that uses interconnections that are not only bendable, but also stretchable. These new interconnections, made of a rubbery transparent material called PDMS, guide light along their path even when stretched up to 30% and when bent around an object the diameter of a human finger.

Controlling magnetism with an electric field

February 19, 2014 8:16 am | by Marie Guma-Diaz and Annette Gallagher UM News | News | Comments

There is a big effort in industry to produce electrical devices with more and faster memory and logic. Magnetic memory elements, such as in a hard drive, and in the future in what is called MRAM (magnetic random access memory), use electrical currents to encode information. However, the heat which is generated is a significant problem, since it limits the density of devices and hence the performance of computer chips.

Smarter caching

February 19, 2014 7:32 am | by Larry Hardesty, MIT News Office | News | Comments

Computer chips keep getting faster because transistors keep getting smaller. But the chips themselves are as big as ever, so data moving around the chip, and between chips and main memory, has to travel just as far. As transistors get faster, the cost of moving data becomes, proportionally, a more severe limitation. So far, chip designers have circumvented that limitation through the use of “caches”.

February 10, 2014 12:07 pm | by Terry Collins, Associated Press | News | Comments

Legislation unveiled in California would require smartphones and other mobile devices to have a "kill switch" to render them inoperable if lost or stolen. State Sen. Mark Leno, San Francisco District Attorney George Gascon and other elected and law enforcement officials say the bill, if passed, would require mobile devices sold in or shipped to California to have the anti-theft devices starting next year.

Artificial hand feels what you touch

February 6, 2014 12:23 pm | by Lauran Neergaard, AP Medical Writer | News | Comments

It's not quite the bionics of science fiction, but European researchers have created a robotic hand that gave an amputee a sense of touch he hadn't felt in a decade. The experiment lasted only a week, but it let the patient feel if different objects were hard or soft, slim or round, and intuitively adjust his grasp.
