Joytone Final Demo. Qualcomm Toq Smartwatch for Android Devices. One Per Cent: Laser-powered 'unprinter' wipes documents in a flash. Paul Marks, senior technology correspondent The letters e, x and t in multiple toner colours have been laser vaporised - and the scanning electron micrograph shows where paper cellulose has been exposed by the beam (pic: CU) In offices the world over, heaps of printouts and photocopies from laser printers get used once before being discarded, or tossed on shelves to collect dust indefinitely.
But what if they could be wiped clean and used again? An engineering team at the University of Cambridge in the UK has figured out how to erase pages by vaporising common toners using a laser-based technique that doesn't damage the underlying paper. Toshiba of Japan already sells a special laser printer/copier (video) that uses a blue toner which can be almost completely erased with heat treatment. Introducing our smart contact lens project. You’ve probably heard that diabetes is a huge and growing problem—affecting one in every 19 people on the planet.
But you may not be familiar with the daily struggle that many people with diabetes face as they try to keep their blood sugar levels under control. Uncontrolled blood sugar puts people at risk for a range of dangerous complications, some short-term and others longer term, including damage to the eyes, kidneys and heart. A friend of ours told us she worries about her mom, who once passed out from low blood sugar and drove her car off the road. Many people I’ve talked to say managing their diabetes is like having a part-time job. Glucose levels change frequently with normal activity like exercising or eating or even sweating.
Architecture. One Step Closer to Hover Boards: Three-Dimensional Mid-Air Acoustic Manipulation. While we’ve seen examples of objects suspended mid-air using quantum levitation and acoustic levitation, a team of three Japanese engineers from The University of Tokyo and the Nagoya Institute of Technology recently unveiled an ambitious device that uses sound waves to move objects through three dimensional space.
The machine uses four arrays of speakers to make soundwaves that intersect at a focal point that can be moved up, down, left, and right using external controls. You would think such machine would be extremely loud, but according to one of the engineers the device uses ultrasonic speakers and is almost completely silent. MIT Invents A Shapeshifting Display You Can Reach Through And Touch. We live in an age of touch-screen interfaces, but what will the UIs of the future look like?
Will they continue to be made up of ghostly pixels, or will they be made of atoms that you can reach out and touch? At the MIT Media Lab, the Tangible Media Group believes the future of computing is tactile. Invisible helmet deploys instantly to save bikers' lives. 'The more we looked into the mystery of Crispr, the more interesting it seemed' - Science - News. Crispr stands for “clustered regularly interspaced short palindromic repeats”, a devilishly contrived acronym which just about sums up why it was ignored for so long.
For nearly two decades after Japanese researchers first discovered Crispr in bacteria in 1987, scientists mostly dismissed it as “junk DNA”. In fact, the apparently nonsensical sequences within Crispr, which were repeated in palindromic order (the same backwards as forwards), did have a purpose and were far from junk. About six years ago, scientists discovered that these DNA sequences matched the genetic sequences of various viruses that attack bacteria, which led to the discovery of a sophisticated bacterial immune system. Far from being junk, Crispr was actually a way of storing the genetic information of an invading virus in the form of a palindromic DNA sequence.
3D Printing the Impossible: A Ship in a Bottle (Video) Physicists Discover Geometry Underlying Particle Physics. Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.
“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work. The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Outside In. Cubli – A cube that can jump up, balance, and – soon- walk across your desk. Update: New video of final robot!
My colleagues at the Institute for Dynamic Systems and Control at ETH Zurich have created a small robotic cube that can autonomously jump up and balance on any one of its corners. Update This latest version of the Cubli can jumping up, balanc, and even “walk”. This new version is self contained with respect to power and uses three slightly modified bicycle brakes instead of the metal barriers used in the previous version.

Scientists Invent Oxygen Particle That If Injected, Allows You To Live Without Breathing. New lithium-ion battery design that’s 2,000 times more powerful, recharges 1,000 times faster. Researchers at the University of Illinois at Urbana-Champaign have developed a new lithium-ion battery technology that is 2,000 times more powerful than comparable batteries.
According to the researchers, this is not simply an evolutionary step in battery tech, “It’s a new enabling technology… it breaks the normal paradigms of energy sources. It’s allowing us to do different, new things.” 3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111.

Vijay Kumar: Robots that fly ... and cooperate. Trillibyte. Threshold broken for tiny lasers. 8 February 2012Last updated at 19:09 The cavity where the laser light is generated is less than 100 billionths of a metre across Scientists have shown off the smallest-ever laser that works at the colours of light used in telecommunications and at room temperature. The tiny light sources switch on with no "threshold", meaning they operate much more efficiently than earlier, small laser attempts. They are just one-fifteenth the size of the light waves that they produce.
