MIT engineers design 'living materials'

March 24, 2014 9:27 am | by EurekAlert! | News | Comments

Inspired by natural materials such as bone — a matrix of minerals and other substances, including living cells — MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving materials, such as gold nanoparticles and quantum dots....

Could diamonds be a computer's best friend?

March 24, 2014 9:22 am | by EurekAlert! | News | Comments

Landmark experiment reveals the precious gem's potential in computing: or the first time, physicists have demonstrated that information can flow through a diamond wire. In the experiment, electrons did not flow through diamond as they do in traditional electronics....

Volvo thinks magnets could guide development of autonomous cars

March 24, 2014 9:20 am | by Allegra Sparta, Contributor | Blogs | Comments

Autonomous cars seem to be the future of individual transportation. Personally, I’ve never minded lengthy drives — just throw on some tunes and cruise along to your destination. But for commuters and other motorists, self-driving cars could be the answer to their problems....


Unavoidable disorder used to build nanolaser

March 24, 2014 9:17 am | by EurekAlert! | News | Comments

Researchers at the Niels Bohr Institute in collaboration with DTU have discovered that imperfect nanostructures can offer entirely new functionalities. They have shown that imperfect optical chips can be used to produce 'nanolasers', which is an ultimately compact and energy-efficient light source. The results are published in the scientific journal Nature Nanotechnology.


Should we use technology to punish prisoners infinitely?

March 24, 2014 8:56 am | by Daniele DeAngelis Walker, Editorial Intern | Blogs | Comments

Life extension and enhancement technology: Gift or curse? May be the latter, at least for prisoners. In the digital age, capital punishment becomes more complicated. If we make lifetimes infinite, what will happen to life sentences? New technologies seek to alter prisoners’ experiences of time....


Academics spy weaknesses in Bitcoin’s foundations

March 24, 2014 1:11 am | by MIT Technology Review | News | Comments

Game theory suggests the rules governing Bitcoin may need to be updated if the currency is to endure.One thing cannot be disputed about the person (or persons) responsible for creating Bitcoin: they were skilled in math, and expert at coding. Five years after the Bitcoin software was first...

How advanced mobile networks could power themselves

March 24, 2014 12:11 am | by MIT Technology Review | News | Comments

Cellular networks guzzle electricity and diesel fuel, but researchers are showing how new versions could be cleaner but still reliable.A dirty secret of mobile communications is that it uses lots of electricity. It’s also sometimes powered by giant tanks of diesel fuel....

Parallel programming may not be so daunting

March 23, 2014 11:15 pm | by Massachusetts Institute of Technology | News | Comments

Computer chips have stopped getting faster: The regular performance improvements we’ve come to expect are now the result of chipmakers’ adding more cores, or processing units, to their chips, rather than increasing their clock speed. In theory, doubling the number of cores doubles the chip’s...


Climate change project aims to educate public, policymakers on risks

March 22, 2014 8:09 am | by AllVoices | News | Comments

If Republicans win control of the US Senate this November, widely considered within the realm of the possible if not the probable, Oklahoma Sen. James Inhofe believes he will once again lead the Environment and Public Works Committee, now chaired...

President Obama wants to switch to an Android phone

March 21, 2014 11:09 pm | by AllVoices | News | Comments

When Barack Obama was elected president in 2008, he insisted on keeping his BlackBerry even though White House policy did not allow the commander-in-chief to use a smartphone. "They're going to pry it out of my hands," he said at the time....

Super junction MOSFETs improve power efficiency, reduce product footprint

March 21, 2014 4:35 pm | Toshiba America Electronic Components | Product Releases | Comments

Toshiba America Electronic Components (Irvine, CA) has introduced a new series of high-speed switching type super junction MOSFETs. The new DTMOS IV-H series consists of the TK31N60X, TK39N60X and TK62N60X, and is based on Toshiba's fourth generation 600V super junction MOSFET DTMOS IV series....


Flexible-boot cable assemblies support low profile installations

March 21, 2014 4:07 pm | Molex | Product Releases | Comments

Molex Incorporated (Lisle, IL) introduces FlexiBend MPO/MTP* flexible-boot cable assemblies designed to optimize cable routing and support low profile installations where cabinet doors or front panels might interfere with traditional straight style bend limiting boots....


Successful development of a high-temperature superconducting magnet for next-generation flywheels

March 21, 2014 3:54 pm | News | Comments

The Railway Technical Research Institute (hereinafter called "RTRI") and Furukawa Electric Co., Ltd. (hereinafter called "Furukawa Electric") have been the first in the world to succeed at the development of a high-temperature superconducting magnet for large flywheels....


Tracking urban change and flood risk with Landsat

March 21, 2014 3:38 pm | by EurekAlert! | News | Comments

Landsat data, which can identify areas of urbanization, are used by the Federal Emergency Management Agency as a key indicator of sites where the agency should further investigate the potential for flooding. Landsat images help track urban change, a factor that can impact a community’s flood risk. The Federal Emergency Management Agency, or FEMA, uses these images to help identify where they should launch a new flood study.


Gene silencing instructions acquired through 'molecular memory' tags on chromatin

March 21, 2014 3:18 pm | by EurekAlert! | News | Comments

Scientists unlocked one of the mysteries of modern genetics: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds that cells don't know to silence some genes based on information hardwired into their DNA sequences....
