Aubrey de Grey Aubrey David Nicholas Jasper de Grey (/dəˈɡreɪ/; born 20 April 1963[5])[6] is an English author and theoretician in the field of gerontology and the Chief Science Officer of the SENS Research Foundation. He is editor-in-chief of the academic journal Rejuvenation Research, author of The Mitochondrial Free Radical Theory of Aging (1999) and co-author of Ending Aging (2007). He is known for his view that medical technology may enable human beings alive today to live to lifespans far in excess of any existing authenticated cases.

Contact Lens? Or...Mouse?? This one’s kinda hard to swallow so take a deep breath, open your minds, and pretend it’s 2100. I CONTACT is essentially a mouse fitted to your eyeball. The lens is inserted like any other normal contact lens except it’s laced with sensors to track eye movement, relaying that position to a receiver connected to your computer. Brilliant: This Android app lets blind users type on a touchscreen [Video] Ankit Daftery is an engineering student at the Veermata Jijabai Technological Institute in Mumbai, India and he decided to take it upon himself to add the ability for the blind to type on an Android device. He was convinced he could add Braille support to the mobile platform. Today, he is starting to turn that idea into a reality. OnlyGizmos brings us this video where the enterprising student earnestly speaks about BrailleType, a simple but ingenious application that will allow blind people to type on a smartphone using the Braille alphabet much in the same way that they use it for reading. BrailleType gives the user a blank canvas, with the top 90% of the screen available to the user for entering in the characters and a strip at the bottom displaying them as they are typed, in addition to reading them out using Android’s built-in text-to-speech synthesiser.

Cognitive radio Description[edit] In response to the operator's commands, the cognitive engine is capable of configuring radio-system parameters. These parameters include "waveform, protocol, operating frequency, and networking". This functions as an autonomous unit in the communications environment, exchanging information about the environment with the networks it accesses and other cognitive radios (CRs). A CR "monitors its own performance continuously", in addition to "reading the radio's outputs"; it then uses this information to "determine the RF environment, channel conditions, link performance, etc

New Biosensor Finds Bacteria In Seconds A new project from Spain has created a means of detecting water borne bacteria in seconds. Drinking the water in a foreign country always seems like something of a gamble. Could be clean, could be a one way trip to spending the entirety of your vacation in the bathroom. Keeping a lid on your digital DNA - tech - 16 October 2011 GENETIC sequencing will soon be cheap enough for everyone to have a digital copy of their own genome. But that also means someone could hack your hard drive or mobile device and gain access to it. If you thought having your email hacked was bad, wait until some digital ne'er-do-well makes off with the information they need for a paternity test. Encrypting the data is the obvious solution, but how?

IBM produces first working chips modeled on the human brain IBM has been shipping computers for more than 65 years, and it is finally on the verge of creating a true electronic brain. Big Blue is announcing today that it, along with four universities and the Defense Advanced Research Projects Agency (DARPA), have created the basic design of an experimental computer chip that emulates the way the brain processes information. IBM’s so-called cognitive computing chips could one day simulate and emulate the brain’s ability to sense, perceive, interact and recognize — all tasks that humans can currently do much better than computers can.

LHSee - Large Hadron Collider app - Big bang science in your pocket (PhysOrg.com) -- Want to find out how to Hunt the Higgs Boson using your phone? Ever wondered how the Large Hadron Collider experiments work, and what the collisions look like? Scientists at the world's biggest scientific experiment - the Large Hadron Collider (LHC)at CERN, Geneva - are trying to answer fundamental questions about the nature of the Universe, the origin of mass, the structure of space and time, and the conditions of the early universe. For those of us not lucky enough to have the world's highest energy particle smasher in our own back gardens, we can still get close to the action using an exciting new smartphone App.

Exocortex An exocortex is a theoretical artificial external information processing system that would augment a brain's biological high-level cognitive processes. An individual's exocortex would be composed of external memory modules, processors, IO devices and software systems that would interact with, and augment, a person's biological brain. Typically this interaction is described as being conducted through a direct brain-computer interface, making these extensions functionally part of the individual's mind. Individuals with significant exocortices could be classified as cyborgs or transhumans. Acoustics Principles For those looking to gain a deeper understanding of how audio works, whether to make better-informed decisions or simply for the sake of curiosity, it's useful to lay down some ground rules that govern how audio systems behave relating to loudness and the decibel. One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level. It’s abbreviated dB.

Laser light used to cool object to quantum ground state For the first time, researchers at the California Institute of Technology (Caltech), in collaboration with a team from the University of Vienna, have managed to cool a miniature mechanical object to its lowest possible energy state using laser light. The achievement paves the way for the development of exquisitely sensitive detectors as well as for quantum experiments that scientists have long dreamed of conducting. "We've taken a solid mechanical system—one made up of billions of atoms—and used optical light to put it into a state in which it behaves according to the laws of quantum mechanics. In the past, this has only been achieved with trapped single atoms or ions," says Oskar Painter, professor of applied physics and executive officer for applied physics and materials science at Caltech and the principal investigator on a paper describing the work that appears in the October 6 issue of the journal Nature.
