A tool able to generate remote forces would allow us to handle dangerous or fragile materials without contact or occlusions. Acoustic levitation is a suitable technology since it can trap particles in air or water. However, no approach has tried to endow humans with an intertwined way of controlling it. Previously, the acoustic elements were static, had to surround the particles and only translation was possible. Here, we present the basic manoeuvres that can be performed when levitators are attached to our moving hands. A Gauntlet of Levitation and a Sonic Screwdriver are presented with their manoeuvres for capturing, moving, transferring and combining particles. Manoeuvres can be performed manually or assisted by a computer for repeating patterns, stabilization and enhanced accuracy or speed. The presented prototypes still have limited forces but symbolize a milestone in our expectations of future technology.

High-efficiency power amplifier could bring 5G cell phones
Posted by Karen Hurst in categories: computing, internet, mobile phones, space, transportation
WEST LAFAYETTE, Ind. – A new highly efficient power amplifier for electronics could help make possible next-generation cell phones, low-cost collision-avoidance radar for cars and lightweight microsatellites for communications.
Fifth-generation, or 5G, mobile devices expected around 2019 will require improved power amplifiers operating at very high frequencies. The new phones will be designed to download and transmit data and videos faster than today’s phones, provide better coverage, consume less power and meet the needs of an emerging “Internet of things” in which everyday objects have network connectivity, allowing them to send and receive data.
Power amplifiers are needed to transmit signals. Because today’s cell phone amplifiers are made of gallium arsenide, they cannot be integrated into the phone’s silicon-based technology, called complementary metal-oxide-semiconductor (CMOS). The new amplifier design is CMOS-based, meaning it could allow researchers to integrate the power amplifier with the phone’s electronic chip, reducing manufacturing costs and power consumption while boosting performance.

Theorists smooth the way to modeling quantum friction
Posted by Karen Hurst in categories: chemistry, computing, information science, particle physics, quantum physics
Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study was published in the Journal of Physical Chemistry Letters (“Wigner–Lindblad Equations for Quantum Friction”). “It was truly a most challenging research project in terms of technical details and the need to draw upon new ideas,” said Denys Bondar, a research scholar in the Rabitz lab and corresponding author on the work.
Researchers construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion. In particular, a translationary invariant Lindblad equation is derived satisfying the appropriate dynamical relations for the coordinate and momentum (i.e., the Ehrenfest equations). Numerical simulations establish that the model approximately equilibrates. (© ACS)

IBM scientists achieve storage memory breakthrough
Posted by Shailesh Prasad in categories: computing, electronics, internet
For the first time, scientists at IBM Research have demonstrated reliably storing 3 bits of data per cell using a relatively new memory technology known as phase-change memory (PCM).
The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But in the last several years PCM has attracted the industry’s attention as a potential universal memory technology based on its combination of read/write speed, endurance, non-volatility and density. For example, PCM doesn’t lose data when powered off, unlike DRAM, and the technology can endure at least 10 million write cycles, compared to an average flash USB stick, which tops out at 3,000 write cycles.

Nanorobots: Where We Are Today and Why Their Future Has Amazing Potential
Posted by Klaus Baldauf in categories: computing, health, nanotechnology, robotics/AI
This post is a status update on one of the most powerful tools humanity will ever create: nanotechnology (or nanotech).
My goal here is to give you a quick overview of the work going on in labs around the world, and the potential applications this nanotech work will have in health, energy, the environment, materials science, data storage and processing.
As artificial intelligence has been getting a lot of the attention lately, I believe we’re going to start to see and hear about incredible breakthroughs in the nanotech world very soon.

This electric jet can take off vertically but drives like a car
Posted by Shailesh Prasad in categories: computing, transportation
With zero emissions and zero runway, the Lilium Jet will be the world’s first entirely electric jet capable of a vertical takeoff and landing (VTOL). Able to fly up to an altitude of about 9,800 feet, the two-person airplane will have a cruising speed of 180 mph, a maximum speed of about 250 mph, and a range of 300 miles. At the forefront of functionality, the environmentally conscious conveyance will also be able to fold back its wings and be driven as a car.
To provide lift and keep the craft aloft, a series of tiltable electric engines will generate a combined 435 hp. Steering and navigation is done through a computer-assisted control system, and the only requisite to operate the vehicle will be a Sport Pilot License (SPL) requiring a minimum of 20 hours of flight time.
Lilium Aviaiton.

Wormholes could be the key to beating the Heisenberg’s uncertainty principle, say physicists
Posted by Andreas Matt in categories: computing, physics, space, time travel
Time travel seems much more common in science fiction than it is in reality. We’ve never met anyone from the future, after all. But all of the physics we know indicates that wormholes — another science fiction favourite — could really be used to travel backwards in time.
And according to a paper by Chinese physicists, using wormholes for time travel might actually allow us to beat Heisenberg’s uncertainty principle — described as one of the most famous (and probably misunderstood) ideas in physics — and even to solve some of the most difficult problems in computer science.
Wormholes are like portals between two places in the Universe. If you fell in one side, you’d pop out the other immediately, regardless of how far apart the two sides were. But wormholes are also like portals between two times in the Universe. As Carl Sagan liked to say, you wouldn’t just emerge some where else in space, but also some when else in time.
