Brain Chip Helps Quadriplegics Move Robotic Arms with Their Thoughts
Reach out: In a clinical trial, a woman used a brain-chip system to control a robotic arm with her thoughts and reach for a drink of coffee. A paralyzed patient equipped with an implanted brain chip has been able to use a robotic arm to reach for and pick up a bottle of coffee, bring it close enough to her face so she could drink from a straw, and then place the bottle back on the table. The quadriplegic patient was outfitted with an electronic brain implant that can drive a robotic arm to reach and grasp objects ( see video ). A study published today in the journal Nature shows that people with the brain chips can use the devices to perform complex three-dimensional tasks that could be helpful in daily life. Furthermore, the implanted electrodes can record neuronal signals for as long as five years—longer than had been suspected.Cyber war

Make A Cheap & Easy Solar USB Charger
Photos by Joshua Zimmerman The craftster behind the very popular $3 solar-powered emergency radio is back with a new awesome project: a cheap solar battery charger with a USB plug. Zimmerman wrote, saying that he saw a lot of small solar powered chargers being talked about over Earth Day, but there was a big problem:

Large Hadron Collider scientists think they may have disproved a law of physics by breaking the speed of light
ASTONISHED scientists are in complete shock after they apparently blew apart one of the basic laws of physics. Researchers say they have recorded particles travelling faster than the speed of light – something that was understood to be impossible. Subatomic particles were beamed from the Large Hadron Collider near Geneva towards a lab 450 miles away in Italy and they arrived a fraction of a second quicker than they should have.
OPERA experiment
The Oscillation Project with Emulsion -tRacking Apparatus ( OPERA ) is an instrument used in a scientific experiment for detecting tau neutrinos from muon neutrino oscillations . The experiment is a collaboration between CERN in Geneva , Switzerland , and the Laboratori Nazionali del Gran Sasso (LNGS) in Gran Sasso , Italy and uses the CERN Neutrinos to Gran Sasso (CNGS) neutrino beam. The process starts with protons from the SPS at CERN being fired in pulses at a carbon target to produce pions and kaons . These particles decay to produce muons and neutrinos . [ 1 ] [ edit ] Detector OPERA, in Hall C of the Gran Sasso underground labs, was built in 2003–2008.
Special relativity
USSR postage stamp dedicated to Albert Einstein Special relativity ( SR , also known as the special theory of relativity or STR ) is the physical theory of measurement in an inertial frame of reference proposed in 1905 by Albert Einstein in the paper " On the Electrodynamics of Moving Bodies ". [ 1 ] Galileo Galilei had already postulated that all uniform motion is relative, and that there is no absolute and well-defined state of rest (no privileged reference frames ), a principle now called Galileo's principle of relativity . Einstein extended this principle so that it accounted for the constant speed of light, [ 2 ] a phenomenon that had been recently observed in the Michelson-Morley experiment . He also postulated that it holds for all the laws of physics , including both the laws of mechanics and of electrodynamics , whatever they may be. [ 3 ]
Albert Einstein ( pron.: / ˈ æ l b ər t ˈ aɪ n s t aɪ n / ; German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen ) ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity , one of the two pillars of modern physics (alongside quantum mechanics ). [ 2 ] [ 3 ] While best known for his mass–energy equivalence formula E = mc 2 (which has been dubbed "the world's most famous equation"), [ 4 ] he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect ". [ 5 ] The latter was pivotal in establishing quantum theory .

Introduction We have been developing various kinds of robotic systems, such as snake-like arms and locomotors based on the biomechanical study of the real snake, quadruped walking robots, and crawler vehicles.

Most member states of the European Union have signed the Anti-Counterfeiting Trade Agreement ( ACTA ) at a ceremony in Tokyo, Japan on Thursday, Jan. 26. ACTA is a global treaty that tries to normalize copyright protection and IP standards. It's similar to SOPA and PIPA , proposed U.S. laws which have recently been dropped after massive internet protests, but in many ways even more dangerous .
