Litecoin is an alternative to Bitcoin (BTC) that is designed to reduce the comparative advantage of using custom ASICs (or GPUs) for mining it relative to using a conventional CPU. Its future is even less certain that BTC, of course, as a later comer, but the technically interesting bits lie in its proof-of-work hash function: …
The three major economic mega-urban zones are the pearl river delta in the south (merging into one 42 million person city) and Yangtze River delta around Shanghai and the Bohai economic rim The area around Beijing and Tianjin, two of China’s most important cities, is being ringed with a network of high-speed railways that will …
Wired Danger Room – North Korea fired artillery at an inhabited South Korean island and South Korea returned fire. Two South Korean marines were killed. At least two South Korean marines are dead and over a dozen are wounded after North Korea fired off hundreds of artillery rounds at a South Korean island. Time has …
A mark-length write strategy for multiterabit per square inch scanned-probe memories is described that promises to increase the achievable user density by at least 50%, and potentially up to 100% or more, over conventional approaches. The new study shows how the density could be increased to 10 Tbit/in^2 or more. The viability of the write …
Again there are people complaining that the vision of Eric Drexler was not realized after 25 years since he wrote Engines of Creation and other research papers on molecular nanotechnology. However, almost no money was spent funding the research and development of molecular nanotechnology. Significant amounts of money were devoted to mostly relabeled chemistry starting …

It will address some of the practical ways in which we can …
EETimes reports from International Solid State Circuit Conference (ISSCC) For processors, silicon could scale to the 7.9-nm node, which is slated for 2024. Reasons Graphene is the post-CMOS Favorite by James Meindl, director of the Joseph M. Pettit Microelectronics Research Center : 1. Graphene has a mechanical strength-to-weight ratio exceeding that of any known material. …
Ralph Merkle discusses the contributions of Robert Freitas to Molecular Nanotechnology. Ralph gives his introduction to molecular manufacturing. Many development pathways and the a convergence to develop core molecular manufacturing capabilities. Robert has contributed on the development pathways and the design and understanding of nanomedicine. * Nanomedicine Volume I basic capabilities book 1999 * Nanomedicine …
The Navy’s second littoral combat ship, the Independence, finished its builder’s trials Wednesday. The aluminum trimaran hit a top speed of 45 knots [50mph] and kept a sustained speed of 44 knots during its full power run in the Gulf of Mexico, shipbuilder General Dynamics said in an announcement. It kept a high speed and …
University of Washington (UW) researchers have succeeded in engineering human tissue patches free of some problems that have stymied stem-cell repair for damaged hearts. Pre-formed blood vessels in patches connect to rodents’ heart circulation. The disk-shaped patches can be fabricated in sizes ranging from less than a millimeter to a half-inch in diameter. Until now, …
Scientists from the United States and China have revealed the potential for human stem cells to provide a vaccination against colon cancer, reports a study published inthe journal Stem Cells. “Although we have only tested the protection against colon cancer, we believe that stem cells might be useful for generating an immune response against a …
