Quantum Simulation with Ultracold Quantum gases, trapped ions, photonic quantum simulators and superconductors

April 7, 2017April 29, 2012 by Brian Wang

Nature Physics has several articles about Quantum simulation Before the advent of digital computers, sophisticated orreries were used to predict the positions and motions of astronomical bodies. Today, we are witnessing the renaissance of devices that simulate, rather than calculate, the evolution of complex many-body systems. Quantum simulators — which use one controllable quantum system …

Skin transformed into liver cells to treat an inherited disease

April 7, 2017April 12, 2012 by Brian Wang

Guardian UK – Scientists have taken skin cells from a patient with liver disease and turned them into replacement liver cells, in a biological tour de force that promises to transform how the condition is treated. The procedure will have to undergo several years of trials before it can be used in humans, but if …

More Evidence that the Mars Viking Probes ‘Found Life’

April 7, 2017April 12, 2012 by Brian Wang

Discorvery News – Mathematical analysis adds to growing body of work questioning the negative results of a life-detection experiment 36 years ago. The new study took a different approach. Researchers distilled the Viking Labeled Release data, provided as hard copies by the original researchers, into sets of numbers and analyzed the results for complexity. Since …

More Energy Efficient Transistors through Quantum Tunneling

April 7, 2017March 27, 2012 by Brian Wang

Researchers at the University of Notre Dame and Pennsylvania State University have announced breakthroughs in the development of tunneling field effect transistors (TFETs), a semiconductor technology that takes advantage of the quirky behavior of electrons at the quantum level. TFETs are on track to solve power leakage and heat problems of regular transistors and delivering …

China’s Air Force Modernizes On Dual Tracks

April 7, 2017March 16, 2012 by Brian Wang

Aviation Week – As China starts to put together a modern, integrated air force, which could reach 1,000 fighters by 2020, it is developing the components of a future force of stealthier combat aircraft, new bombers and unmanned, hypersonic and possibly space-based combat platforms. These could emerge as soon as the early 2020s. This dual …

Startram could usher in era of low-cost space travel

April 7, 2017February 27, 2012 by Sander Olson

Next Big Future has covered the Startram concept in detail before. The GEN 1 concept involves using long, evacuated tunnels to accelerate unmanned payloads to orbital velocity. In theory, this concept could bring launch costs to LEO down to $50 dollar per kilogram. A more ambitious GEN 1.5 system could would take longer and greater …
