In this phase diagram common to many cuprate superconductors, the insulating phase typical of undoped cuprate compounds appears at the far left (black). Other phases appear with increased hole doping – the dome-shaped superconducting phase below Tc (blue), the mysterious pseudogap below T* (red), and a “normal metallic” phase (white). New evidence from studies of …
A record 262 aftershocks of magnitude 5 or greater were registered in the seven days following the magnitude 9.0 earthquake off northeastern Japan on March 11, Kyodo News quoted the Japan Meteorological Agency as saying Friday. There were three aftershocks of magnitude 7 or greater, including one magnitude 7.5 that occurred shortly afterwards, and 49 …
On Friday the first day of the quake, Google’s offices in Tokyo’s Roppongi district contacted Google.org, their employer’s philanthropic arm, to suggest it should get involved in the emergency response, as it had after recent earthquakes in Haiti, Chile and New Zealand. Within an hour, and with aftershocks still rocking Tokyo, the Japan Person Finder …
Official global poverty estimates are only rarely produced, and when they do appear, they are out of date by the time they are published. Thus, when world leaders met in September 2010 to assess progress toward reaching the Millennium Development Goal of halving global poverty, they had to rely on poverty data from 2005. By …
Chemistry of Materials – Self-Templating of Metal-Driven Supramolecular Self-Assembly: A General Approach toward 1D Inorganic Nanotubes The rational design of one-dimensional (1D) inorganic nanomaterials directed by self-assembled soft matters is one of the most attractive subjects in modern chemistry. In this work, the self-templating approach based on metal−cholate supramolecular self-assemblies is reported, which is distinct …
New Scientist – Artificial intelligence has finally become trustworthy enough to watch over everything from nuclear bombs to premature babies. Given the choice between a flesh-and-blood doctor and an artificial intelligence system for diagnosing diseases, Pedro Domingos is willing to stake his life on AI. “I’d trust the machine more than I’d trust the doctor,” …
Joseph Zawodny, NASA Langley Research Center – Energetics, had a presentation at NASA Aviation Unleashed where he looked at low energy nuclear reactions and other possible game changing technologies. Lewis G. Larsen developed a theory of LENRs (WLT) that explains ALL the evidenceand along with Dr. Alan Widom published their theory in Eur. Phys. J. …
New research at Rice University could ultimately show scientists the way to make batches of nanotubes of a single type. A paper in the online journal Physical Review Letters unveils an elegant formula by Rice University physicist Boris Yakobson and his colleagues that defines the energy of a piece of graphene cut at any angle. …
According to a new report from Pike Research, algae biofuels production will grow rapidly over the next decade, reaching 61 million gallons per year and a market value of $1.3 billion by 2020. While barely a drop in the bucket for biofuels, this represents a compound annual growth rate (CAGR) of 72%, roughly on par …
IS OUR universe a recycled version of an earlier cosmos? The idea, which replaces the big bang with a “big bounce”, has received a boost: this vision of the birth of the universe can explain why a subsequent process, called inflation, occurred. http://www.newscientist.com/article/mg20827825.200-big-bounce-cosmos-makes-inflation-a-sure-thing.html?DCMP=OTC-rss&nsref=online-news If you liked this article, please give it a quick review on …
