Steve Ballmer stated and Andy Lees confirmed that Microsoft views iPad and other tablets as “just PCs”. Windows continues to be dominant with 84% of units sold in the last quarter, the growth belongs to tablets which captured about 90% of it. If Windows remains marginal on tablets, the “PC market” will likely tip away …
Caltech researchers are the first to have made an artificial neural network out of DNA, creating a circuit of interacting molecules that can recall memories based on incomplete patterns, just as a brain can. “The brain is incredible,” says Lulu Qian, a Caltech senior postdoctoral scholar in bioengineering and lead author on the paper describing …
Scientists from the A*STAR Institute of High Performance Computing and the National University of Singapore have now developed a technique that collapses spherical carbon nanostructures down into perfectly formed quantum dots—structures useful for electronics because of their ability to trap single electrons. The carbon atoms in graphite are arranged into stacked sheets that are weakly …
ECat World – A reporter from XanthiPress, a Greek news site based in Xanthi, conducted an interview with Alexandros Xanthoulis, President of Defkalion Green Technologies The Greek interview is here through google translate At the first 2 weeks of August a core team of 12 scientists from the Xanthi area will start working, there will …
The project uses fiber-optic devices that make ultrafast calculations with photons of light instead of the electrons used by electricity-based computers circuits. (Photo by Frank Wojciechowski) Princeton University – Paul Prucnal, a Princeton professor of electrical engineering, is leading a collaboration between researchers at the University and Lockheed Martin, the aerospace and defense technology corporation, …
The 61st Carnival of Nuclear Energy is up at ANS Nuclear Cafe Neutron Economy covers an IAEA review of Fukushima. The notes were prepared by Steve Skutnik about a recently attended talk by Randy Beatty of the IAEA, who gave the Agency’s perspective on the Fukushima disaster. -The 50-mile evacuation order by Jaczko was wrong. …
Jeff Head has collected loads of pictures of the reconstruction of the Varyag. This shot is of a Varyag from last month as it is getting outfitted and ready to set sail. There is a lengthy but interesting analysis of China’s growing naval power at military aerospace.com. Seaborne commerce is an essential part of Chinese …
Every year, the International Energy Agency (IEA) publishes the World Energy Outlook Report. On 12 July, IEA Executive Director Nobuo Tanaka appeared before the European Parliament’s Industry, Energy and Research Committee to present a preview of this year’s report, which will be published in November. Tanaka reported that the projections for increase of energy from …
NIST’s “optics table on a chip” is a superconducting circuit on a square sapphire chip about 6 millimeters wide. Scientists use the chip to place a single microwave photon in two frequencies, or colors, at the same time. The photon is prepared by an “artificial atom” (small yellow square) in the middle of the chip. …
Defending Planet Earth [from space asteroids] 15 page presentation from Future of Space Operations talk 4 approaches depending on circumstances * Civil defense (evacuation, sheltering, first aid, etc. – Up to 50 meter in diameter? * Slow Push-Pull (tug, solar heating, albedo change, gravity tractor, et al.) – Needs decades to operate (plus time to …
MHD Generators could make zero emission coal generators affordable and efficient and MHD generators could also make nuclear power for space very light with an energy density of one to three kilograms per kilowatt. Magnets are about 22% of the cost. Superconductors and new permanent magnets (using nanomaterials) could make more powerful magnets that are …
