the system’s “scalable” architecture speaks to a bigger future A 6cm-by-6cm chip holds nine quantum devices, among them four “quantum bits” that do the calculations. The UCSB team said further scaling up to 10 qubits should be possible this year. AAAS journal Science recognized related work in 2010 as the scientific Breakthrough of the year …
George Monbiot- Why Fukushima made me stop worrying and love nuclear power A crappy old plant with inadequate safety features was hit by a monster earthquake and a vast tsunami. The electricity supply failed, knocking out the cooling system. The reactors began to explode and melt down. The disaster exposed a familiar legacy of poor …
Carnival of Space 189 is up at Steves Astrocorner Universe today has satellite before and after photos of areas in Japan hit by the earthquake and tsunami An update of the Sheparding asteroids article is provided by this site. In space it is relatively easy to move quite large space rocks using solar sails, ion …
On Wednesday, Seif Al-Islam Gaddafi, the oldest son of the Libyan dictator, declared that Benghazi will fall within 48 hours. The battle for control of Benghazi looked just hours away on Thursday after the Libyan army ordered people to leave opposition-held locations and arms storage areas. Rebels said they had inflicted heavy losses on government …
a high temperature superconductor emdrive thruster, which operates at 3.8 GHz, and was designed using an update of the software used for the previous S band designs. Super-conducting surfaces are formed from YBCO thin films on sapphire substrates. Small signal testing at 77 deg K confirmed the design, with a Q of 6.8×106 being measured. …
Eetimes – Directed Self Assembly is gathering momentum to be used in major ways for advanced lithography The technology is moving from the lab to a more serious phase of commercial development. In the event that EUV cannot be made commercially viable, there are several other possibilities for future chip scaling, including DSA. But some …
Egyptians on the streets of Cairo said on Monday they had reservations about opposition leader Mohamed ElBarade Egyptian authorities harassed his supporters and ElBaradei lost much credibility through his long absences abroad. The official media tried to ridicule him, saying he knew nothing about Egypt and had no political experience. Some elements of the government’s …
New Energy Times – Energy Catalyzer: It Works and It’s Not Fusion * it is not “cold fusion” but weak [force] nuclear reactions. Pons and Fleischmann did heavy-water electrolysis with a palladium cathode and a platinum anode. I don’t do electrolysis, I don’t use either platinum or palladium and I use temperatures that manage to …
After a one month hiatus, the Carnival of Space is back. Nextbigfuture will be working with Universe today on the organization of the Carnival of Space. There are hosts signed up into April. 1. the Planetary Society has Amateur image processor Daniel Macháček took five images of Phobos from Mars Express’ recent flyby and produced …
Hplus Magazine has detailed coverage on Genescient (life extension company) and their new Stem Cell 100 product I have started taking Stem Cell 100. It is about $60 for a one month supply. I would also recommend supporting SENS rejuvenation research and Robert Freitas’s nanomedicine work (donate through IMM) Genescient’s primary business focus is on …
Arxiv – Pair Creation in QED-Strong Pulsed Laser Fields Interacting with Electron Beams (25 pages) QED-effects are known to occur in a strong laser pulse interaction with a counterpropagating electron beam, among these effects being electron-positron pair creation. We discuss the range of laser pulse intensities of J ≥ 5 · 10^22 W/cm2 combined with …
