A new scheme termed “coherent photon conversion”, could potentially overcome all of the currently unresolved problems for optical implementations of quantum computing. Quantum technology derives its potential by exploiting uniquely quantum features such as superposition and entanglement. Single photons are excellent quantum information carriers, because they are naturally almost perfectly isolated from their environment. Also, …
Samsung and Seoul National University researchers have grown crystalline gallium nitride (GaN) on the surface of amorphous glass. The idea could lead to new, scalable ways of making semiconductor devices that don’t need to be grown on silicon or sapphire wafers. Commercialisation will take at least 10 years. The technique uses a thin layer of …

Bigelow Aerospace, which is developing inflatable space habitats for commercial use, laid off some 40 of its 90 employees Sept. 29. The BA 330 is a six-person inflatable space station Bigelow Aerospace of North Las Vegas, Nev., is developing to serve commercial and government human spaceflight markets. The BA 330 is one of the proposed …
A new “subconscious mode” for smartphones and other WiFi-enabled mobile devices could extend battery life by as much as 54 percent for users on the busiest networks. Here’s how E-MiLi works: It slows down the WiFi card’s clock by up to 1/16 its normal frequency, but jolts it back to full speed when the phone …
Stem cell researchers in Hong Kong and the United States are trying to grow spare parts for the human heart that may be ready for tests on people within five years. (H/T Fightaging) Scientists have already made basic heart muscle from stem cells, but the Hong Kong-led team wants to refine it so it can …
For decades, scientists have known that DNA consists of four basic units — adenine, guanine, thymine and cytosine. In recent history, scientists have expanded that list from four to six. Now researchers from the UNC School of Medicine have discovered the seventh and eighth bases of DNA. These last two bases – called 5-formylcytosine and …
image by Steve Bowers, this power collection swarm consists of thousands of elements in inclined orbits, each with a slightly different ascending node and pericenter. This arrangement ensures the elements never come close to each other. The various orbits form a toroid shape, surrounding the star. Kennedy quote – Some people see things as they …
University of Illinois: Harvesting Low Quality Heat Using Economically Printed Flexible Nanostructured Stacked Thermoelectric Junctions Low quality heat constitutes a 2 TW untapped source of energy in the US. High coefficient of performance thermoelectrics with a figure of merit (ZT) exceeding 1, can potentially harness approximately 4.3% of this waste heat and add up to …
Gamma-ray burst (European Space Agency) ESA’s Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum ‘graininess’ of space must be at much smaller scales than previously predicted. Einstein’s General Theory of Relativity describes the properties of gravity and assumes that space …
NASA and DARPA have a project called the 100 year Starship study. The 100 Year Starship™ Study is an effort seeded by DARPA to develop a viable and sustainable model for persistent, long-term, private-sector investment into the myriad of disciplines needed to make long-distance space travel practicable and feasible. The Icarus project has projected dates …
