An illustration of the insight problems used (PLoS)
Richard Chi and Allan Snyder from the Centre for the Mind at the University of Sydney have found that participants who received electrical stimulation of the anterior temporal lobes were three times as likely to reach the fresh insight necessary to solve a difficult, unfamiliar problem than those in the control group.
According to the researchers, our propensity to rigidly apply strategies and insights that have had previous success is a major bottleneck to making creative leaps in solving new problems. There is normally a cognitive tradeoff between the necessity of being fast at the familiar on one hand and being receptive to novelty on the other.
Chi and Snyder argue that we can modulate this tradeoff to our advantage by applying transcranial direct current stimulation (tDCS), a safe, non-invasive technique that temporarily increases or decreases excitability of populations of neurons. In particular, tDCS can be used to manipulate the competition between the left and right hemisphere by inhibiting and/or disinhibiting certain networks. Their findings are consistent with evidence that the right anterior temporal lobe is associated with insight or novel meaning and that inhibition of the left anterior temporal lobe can induce a cognitive style that is less top-down, less influenced by preconceptions.
While further studies involving brain stimulation in combination with neuroimaging are needed to elucidate the exact mechanisms leading to insight, Chi and Snyder can imagine a future when non-invasive brain stimulation is briefly employed for solving problems that have evaded traditional cognitive approaches.

Graphene's band dispersion and low energy Dirac cone in a monolayer of carbon atoms arranged in a hexagonal lattice (credit: University of Manchester)
They anticipate their findings will accelerate building graphene-based devices such as touchscreens, ultrafast transistors, and photodetectors.
The researchers used extremely high-quality graphene devices, prepared by suspending sheets of graphene in a vacuum. This eliminated most of the unwanted scattering mechanisms for electrons in graphene, enhancing the effect of electron-on-electron interaction.
This is the first effect of its kind where the interactions between electrons in graphene could be clearly seen.
The electrons in graphene behave like massless Dirac particles that appear in the electronic band structure as gapless excitations with a linear dispersion.
“The exciting physics which we have found in this particular experiment may have an immediate implementation in practical electronic devices,” said University of Manchester professor Kostya Novoselov.
Novoselov, together with Professor Francisco Guinea from Madrid, won the Nobel Prize for Physics in 2010 for “groundbreaking experiments regarding the two-dimensional material graphene.” They used Scotch tape to peel away layers of carbon from a piece of graphite, and were left with a single-atom-thick, two-dimensional film of carbon — graphene.

For the first time, the public will be able to get their hands on a video camera that takes incredibly realistic footage thanks to three sensors that collect light and then create an image without having to choose between the over- and under-exposed portions of the picture. Unfortunately, only those who signed up on AMP’s waiting list will be getting the camera when it’s released later this summer, but just to whet your appetite, here’s some video showing its impressive capabilities.

Sebastian Thrun helped build Google's amazing driverless car, powered by a very personal quest to save lives and reduce traffic accidents. Jawdropping video shows the DARPA Challenge-winning car motoring through busy city traffic with no one behind the wheel, and dramatic test drive footage from TED2011 demonstrates how fast the thing can really go."
Creating multiple Google Chrome profiles is fairly easy on a PC, there's even a program for doing all the legwork for you. Not so for the Mac. I could not for the life of me find a decent tutorial on the web for creating multiple user profiles for Google Chrome on OSX, so hopefully this will help. We'll basically be writing a small shell script, which will act like an application for initializing a new Chrome profile and acting like a Windows shortcut thereafter. Here are the steps:
First, open Script Editor (Command Space > Script Editor)
Now, lets say we want to add a new chrome profile for somebody named Susan. Paste the following code into the Script Editor, replace the name "susan" with the profile name you want to use.
do shell script "/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome --user-data-dir=/Users/$USER/Library/Application\\ Support/Google/susan > /dev/null 2>&1 &"
Next, save the Script (File > Save As) in your Application directory. Name it something like "Google Chrome Susan" (replacing Susan with your profile name). Also, make sure to choose "Application" from the File Format drop-down list.
Now you should see a new .app in your Applications folder with the name you gave to the shell script. You can run this application and it should initialize a new profile. Everything should be working now.
If you want to make the new Script/App look a little prettier, you can copy the normal chrome icon to the new .app. To do this first select the regular Chrome Application and select Command I (for Get Info).
See the icon in the top left hand corner of the Info window. Click the icon and select Command C (for Copy). Now go to the new Script/App and Get Info. Now select the icon in the top left and select Command V (for Paste). The icon should change.
After waiting for Spotlight to index the new app you should be able to search for it without a hitch!
