Atomic Insights reports on progress towards extracting Uranium from coal flyash waste. Spartan Resources of Canada, has press releases discussing a project in Hungary and another announced a successful test of samples from an ash pile located in the central Yunnan Province of China. The Yunnan province ash pile being evaluated contains about 5.3 million …
Check out the well written Carnival of Space #25 at sortingoutscience.net My contribution was preview coverage of the space elevator games The interim report on space based solar power is out and sortingoutscience lists many links to sites that are talking about it.I had made several contributions at the space based solar power website. The …
Using a little-known Google Labs widget, computer scientists from UC San Diego and UCLA have brought common sense to an automated image labeling system. This common sense is the ability to use context to help identify objects in photographs. For example, if a conventional automated object identifier has labeled a person, a tennis racket, a …
University of Rochester researchers have patented the device, which they hope will make tests such as identifying proteins in a tiny sample of blood as simple as placing a drop on a handheld device. Laboratories and hospitals all over the world use similar, albeit cumbersome, hours-long processes in efforts to identify everything from DNA fragments …
University of Manchester researchers have transformed fat tissue stem cells into nerve cells — and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life. Dr Paul Kingham and his team at the UK Centre for Tissue Regeneration (UKCTR) isolated the stem cells from the fat tissue of …
Charles Leiber and colleagues at Harvard University describe silicon nanowire they devised that can convert light into electrical energy. Virtually invisible to the naked eye, a single strand can crank out up to 200 picowatts. The nanowire is not made of metal but of silicon with three different types of conductivity arranged as layered shells. …
Known by its lab name of RTS,S the prototype is raising high hopes of the first vaccine shield against a disease that claims more than a million lives a year — 800,000 of them African children aged under five — and sickens hundreds of millions more. Infants who received RTS,S were 65 percent less at …
A 68 page pdf on using Sony PS3’s for scientific computing For a matrix of size 2Kx2K they achieved 11.05 Gflop/s, which is around 75% of the double precision peak. They have also implemented a single precision version of the code, which achieved 155 Gflop/s (again around 75%efficiency) for a matrix of size 4Kx4K. Unfortunately, …
According to Kitegen’s preliminary evaluations, it is expected that wind generators of this type may have much lower electric energy production costs than actual wind farms (by a factor up to 10-20) and could generate up to 250 MW/km2, vs. 3 MW/km2 of wind farms. Reddit With a kite area of 50 m2 , simulations …
The space elevator Games 2010 competition is being covered at the Space elevator blog The competition will be from October 19-21, 2007. The competition has some bad weather issues. There is a space elevator climber competition and a tether competition. Five of the space elevator climber competitors are from Canada REDDIT UPDATE: More live coverage …
The U.S. aluminum giant Alcoa, materials-technology company GTM Advanced Structures and scientists at Delft University of Technology in the Netherlands have patented a fiber metal laminate (FML) called CentrAl reinforced aluminum, or CentrAl, for use in aircraft manufacture. CentrAl provides some 25 percent more tensile strength than high-strength aluminum alloys, is extremely resistant to metal …
