GRAPHENE, a form of carbon that comes in sheets a single atom thick, has gained a reputation as a wonder material. It is the best conductor yet discovered of heat at room temperature and is 40 times stronger than steel. It is also a semiconductor whose electrical conductivity is 1,000 times better than silicon's. This means it could be used to make devices far more sensitive than is possible now, leading some to predict that it will one day become the material of choice for computer chips. There was little surprise, therefore, when Andre Geim and Konstantin Novoselov, two physicists who were investigating graphene's structure, won the 2010 Nobel prize for their work.

Graphene can be used in many industries - from electronics to water purifiers, from displays to super-capacitors and car batteries offering exciting possibilities for this new technologican advance, although.   converting the wonders of graphene into products has been tough. But Frank Koppens and his colleagues at the Institute of Photonic Sciences in Barcelona think they have found a way to do so. As they describe in Nature Nanotechnology, they believe graphene can be used to make ultra-sensitive, low-cost photodetectors.

Social media has empowered brands to break their own news instead of relying on advertising or PR to disseminate their message. As brands become increasingly comfortable with social media on the whole, more budget and attention is being focused on high quality content created specifically for the social web.  New Wave of Advertisers Consider Consumers the New Medium.

    The spot for Chipotle Mexican Grill starts bleak and gets bleaker: the story of a farmer who becomes Big Agriculture, maltreating his pigs and polluting the water as winter descends. It's long, at two minutes and 20 seconds, and told entirely via stop-motion puppetry. There's no dialogue, only the spooky crooning of Willie Nelson. And the Chipotle logo appears just once, at the very end, on a truck pulling away from a farm returned to its roots, chickens pecking freely in the sun.  At any number of companies, the ad would have been killed for any number of reasons. It's unfunny. Political. Expensive to air.  There was also a chance that it was brilliant.

    As of March 1, 2012, whatever you do on one Google-owned site will change whatever you see on another Google property – be it Google' search engine, Docs, Maps, Calendar, Gmail, Picassa, YouTube, G+, etc.

    "We can provide reminders that you're going to be late for a meeting based on your location, your calendar and an understanding of what the traffic is like that day," reads Google's blog explaining the search giant's unified policy. This works whether you're accessing Google on your computer, tablet or cellphone, as long as you're logged in.  "People still have to do way too much heavy lifting, and we want to do a better job of helping them out," Google points out.  What the blog posts fails to mention however, is that it is now better equipped to help out law enforcement officials and the government when it comes to finding out about you.

    Now that Facebook has filed its paperwork to go public, we're getting our first real glimpse at the inner workings of the world's largest social networking website.   Let's set aside the potential for Facebook's valuation to get out hand. We're still several weeks away from actual deal pricing and retail investor reactions.

    Facebook is not going public because it needs to raise money, but by going public the company is giving its early investors a way out and its not going to be cheap.
