On the edge of graphene

August 18, 2014 1:11 pm | by EurekAlert! | Comments

Researchers at the National Physical Laboratory (NPL) have discovered that the conductivity at the edges of graphene devices is different to that of the central material. Local scanning electrical techniques were used to examine the local nanoscale electronic properties....

TUM researchers develop defense against cyberattacks

August 18, 2014 1:02 pm | by EurekAlert! | Comments

Port scanners are programs that search the Internet for systems that exhibit potential vulnerabilities. According to the report published today by journalists at Heise Online, Hacienda is one such port scanning program. The report says that this program is being put into service by the "Five Eyes"....

Bats bolster brain hypothesis, maybe technology, too

August 18, 2014 12:58 pm | by EurekAlert! | Comments

Amid a neuroscience debate about how people and animals focus on distinct objects within cluttered scenes, some of the newest and best evidence comes from the way bats "see" with their ears, according to a new paper in the Journal of Experimental Biology. In fact, the perception process in question ...

Mid-power LEDs to account for 48 percent of the market In 2014

August 18, 2014 12:03 pm | by Jamie Fox, IHS Inc. | Comments

The growing lighting end market in 2014 is now projected to account for 35 percent of all packaged light-emitting diode (LED) dollars, according to IHS. For the first time, this is more than all backlighting combined. In 2013, lighting and backlighting accounted for...

Visual control of big data

August 18, 2014 9:47 am | by EurekAlert! | Comments

In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns?

New X-ray imaging developed by scientists

August 18, 2014 9:45 am | by EurekAlert! | Comments

Scientists have developed an x-ray imaging system that enables researchers to see 'live' how effective treatments are for cystic fibrosis. Published in the American Journal of Respiratory and Critical Care Medicine, the imaging method allows researchers....

Credit allocation among researchers determined by new algorithm

August 18, 2014 9:44 am | by EurekAlert! | Comments

A new algorithm developed at Northeastern's Center for Complex Network Research helps shed light on how to properly allocate credit. The research was published this month in Proceedings of the National Academy of Sciences in a paper co-​​authored by Hua-​​Wei Shen....

Scientists discover interstellar stardust

August 18, 2014 9:41 am | by EurekAlert! | Comments

We may joke about looking for a needle in a haystack, but that's nothing compared to searching for stardust in a foil! A new paper published in Science reveals that such work has led to the discovery of seven dust particles that are not only out of this world, they're out of this solar system....

'Cavity protection effect' helps to conserve quantum information

August 18, 2014 9:38 am | by EurekAlert! | Comments

The electronics we use for our computers only knows two different states: zero or one. Quantum systems on the other hand can be in different states at once, they can store a superposition of "zero" and "one". This phenomenon could be used to build ultrafast quantum computers....

Fascinating rhythm: Light pulses illuminate a rare black hole

August 18, 2014 9:33 am | by EurekAlert! | Comments

The universe has so many black holes that it's impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black holes ranging from about 10 times to 100 times....

Microchip reveals how tumor cells transition to invasion

August 18, 2014 9:28 am | by EurekAlert! | Comments

Using a microengineered device that acts as an obstacle course for cells, researchers have shed new light on a cellular metamorphosis thought to play a role in tumor cell invasion throughout the body. The epithelial-mesenchymal transition (EMT) is a process in which epithelial cells ...

A shift in the code: New method reveals hidden genetic landscape

August 18, 2014 9:24 am | by EurekAlert! | Comments

With three billion letters in the human genome, it seems hard to believe that adding a DNA base here or removing a DNA base there could have much of an effect on our health. In fact, such insertions and deletions can dramatically alter biological function, leading to diseases from autism to cancer....

Artificial cells act like the real thing

August 18, 2014 9:20 am | by EurekAlert! | Comments

Imitation, they say, is the sincerest form of flattery, but mimicking the intricate networks and dynamic interactions that are inherent to living cells is difficult to achieve outside the cell. Now, as published in Science, Weizmann Institute scientists have created an artificial, network-like cell system....

Hitchhiking robot charms its way across Canada

August 18, 2014 9:16 am | by CHARMAINE NORONHA, Associated Press | Comments

He has dipped his boots in Lake Superior, crashed a wedding and attended an Aboriginal powwow. A talking, bucket-bodied robot has enthralled Canadians since it departed from Halifax last month on a hitchhiking journey to the Pacific coast. HitchBOT, created by team of Ontario-based communication researchers ...

Wireless sensors and flying robots: A way to monitor deteriorating bridges

August 15, 2014 12:42 pm | by EurekAlert! | Comments

As a report from the Obama administration warns that one in four bridges in the United States needs significant repair or cannot handle automobile traffic, Tufts University engineers are employing wireless sensors and flying robots that could have the potential to help authorities....
