We covered a stratospheric airship in 2009 They continue to make progress with the STS-111 airship and advance the program closer to hosting customer demonstrations. The platform has performed to the initial specifications they set out for, and they will continue to pursue our ultimate goal of producing a stratospheric platform to serve a number …
The 10-nm process node appears to be the ideal point for the adoption of manufacturing on 450-mm diameter wafers, according Leonard Hobbs, head of research for Intel Ireland. Speaking at the Industry Strategy Symposium here (ISS Europe) he also indicated that the transition could not come sooner and could be pushed later, depending on the …
The Godson-3A chip was implemented in a 65 nanometer process and ran at 1 GHz to deliver 16 gigaflops of floating point oomph. The chip has 425 million transistors, an area of 174.5 square millimeters, and burned only 10 watts under load. The chip included two 16-bit HyperTransport ports (licensed from Advanced Micro Devices), 4 …

Capacitor effect for magnetic monopoles in spin ice. The application of a magnetic potential adds new magnetic monopoles to a crystal of spin ice which then spring apart and store magnetricity. Researchers at the LCN have created a purely magnetic version of one of the basic effects of electronics – the storage and release of …
Arvid Guterstam conducting an experiment. Brain scientists at Karolinska Institutet (sweden) have now shown that it is possible to make healthy volunteers experience having three arms at the same time. A related study at Karolinska is said to have resulted in people perceiving that their physical selves were located not in their own bodies, but …
Congenital heart diseases affect approximately one in 100 patients, making them the most common type of birth defect and the number-one cause of pediatric deaths. Now a new study showing that the mTOR inhibitor drug rapamycin can reverse cardiac muscle damage in a mouse model of the congenital disease LEOPARD syndrome not only identifies the …
ACS Nano – Toward Chemical Propulsion: Synthesis of ROMP-Propelled Nanocars The synthesis and ring-opening metathesis polymerization (ROMP) activity of two nanocars functionalized with an olefin metathesis catalyst is reported. The nanocars were attached to a Hoveyda−Grubbs first- or second-generation metathesis catalyst via a benzylidene moiety. The catalytic activity of these nanocars toward ROMP of 1,5-cyclooctadiene …
