ELF emmit is the world’s first wearable mind stimulating headband, based on pulsed electromagnetic technology. Operates in five different modes: Sleep, Anti-stress, Superlearning, Concentrate, Meditate. Designed to assist you in every area of life. Powered by smart phone or tablet. Operated by free mobile application.
Researchers at the University of Alabama at Birmingham suggest that brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, need better security after a study reveals hackers could guess a user’s passwords by monitoring their brainwaves.
EEG headsets are advertised as allowing users to use only their brains to control robotic toys and video games specifically developed to be played with an EEG headset. There are only a handful on the market, and they range in price from $150 to $800.
Nitesh Saxena, Ph.D., associate professor in the UAB College of Arts and Sciences Department of Computer and Information Sciences, and Ph.D. student Ajaya Neupane and former master’s student Md Lutfor Rahman, found that a person who paused a video game and logged into a bank account while wearing an EEG headset was at risk for having their passwords or other sensitive data stolen by a malicious software program.
It has been more than a decade since the Concorde was retired from service, and since then no passenger aircraft has exceeded the speed of sound. That might change in the not-too-distant future, thanks to a project from NASA and industry partner Lockheed Martin Corporation. The agency is close to testing its design for Quiet Supersonic Transport, or QueSST, which could lead to passenger jets that can again reach supersonic speeds.
The Concorde was never seen as a major commercial success — more of a vanity project for the few European airlines that operated the planes. The nature of supersonic flight meant the sonic boom at ground level could shatter windows. Thus, the plane could only fly at high speeds over the ocean. The trip between Europe and New York was fast, but other routes were not feasible. When the travel industry took a downturn in 2003, the Concorde was mothballed.
QueSST technology has the potential to make supersonic air travel workable even over land, and NASA has announced that its preliminary design review is done. The aim is to build a plane that can fly at supersonic speeds without the disruptive sonic boom. NASA, with the help of Lockheed Martin, has designed and tested a scale model version of the so-called Low Boom Flight Demonstration (LBFD) experimental aircraft, known as an X-plane. This model was placed in a 6-by-8-foot supersonic wind tunnel at NASA’s Glenn Research Center. This led engineers to confirm the fuselage, wing, and engine design could allow for quieter supersonic flight.
Quantum theory says that stuff doesn’t exist when we’re not looking at it. But weirder-than-weird experiments are resurrecting a long-derided alternative.

IN OCTOBER 1951, physicist David Bohm left the US for Brazil. Branded a communist sympathiser, he had been arrested for refusing to testify to the US Congress. Acquitted, he was still stripped of his Princeton professorship. His departure began an exile that would last until his death, as a naturalised British citizen, four decades later.
National Electric Vehicle Sweden, which purchased Saab’s assets back in 2012, is using CES Asia to show its vision of autonomous commuting. Owning a car is out in this particular mobility vision, and vehicles not only pick you up and drop you off autonomously, they change their interiors around your needs and whims. So you enjoy a personalized ride and can make the most of every moment.
