Schematic of the nanoimprint lithography process. The thickness contrast is created in the resist by imprinting (1). The pressure is maintained until the polymer flow fills the cavities of the mold (2). The mold and substrate are cooled below the glass transition temperature and separated (3). Stamp fabrication by step and stamp nanoimprinting (79 pages) …
Battery prototype: Two sludge-like electrode materials are fed into the device shown here. The anode material flows into the top half, and the cathode flows into the bottom. Lithium ions pass from one material to the other, and electrons flow through the black and red leads. Credit: Yet-Ming Chiang MIT Technology Review – A big …
A SOV1 Deletion Extends Life Span without Affecting Steady-State Levels of ROS or Oxidative Damage Mitochondria are the body’s energy producers, the power stations inside our cells. Researchers at the University of Gothenburg, Sweden, have now identified a group of mitochondrial proteins, the absence of which allows other protein groups to stabilise the genome. This …
A report on radiation levels and how much above background it is There is economic loss at the Japan plant but no one will die from radiation. There is no core meltdown. The radiation is less than 1 REM per day. It takes 600 REM to kill BP oil spill had deaths and more damage. …
The University of Nottingham has achieved a world first to provide building blocks for new nano devices. Scientists at The University of Nottingham have made a major breakthrough that could help shape the future of nanotechnology, by demonstrating for the first time that 3-D molecular structures can be built on a surface. The discovery could …
Humanity+ @ CalTech Redefining the Future of Humanity is a conference on December 4-5 Humanity Plus conference registration is here. * Real-Time World Building — Performance Art for the 21st Century It’s not so often that someone introduces a brand new art form to the world, but that’s exactly what polymathic performer/designer/filmmaker/artist/composer J-Walt will demonstrate …
the RATTLR long range missile was studied but not developed. The Defense Advanced Research Project Agency (DARPA) has awarded Lockheed Martin a contract worth $157 million for the development of an advanced long range anti ship missile (LRASM). The new anti-ship missile and its associated systems will extend the effective attack range of Navy warships …
Grandis, Inc., the leader in spin transfer torque random access memory (STT-RAM), today announced that it has been awarded a new contract from the Defense Advanced Research Projects Agency (DARPA) to develop non-volatile spin logic. Under the contract, the company will expand its cutting-edge development of spintronics and advanced magnetic materials beyond non-volatile STT-RAM memory …
Tony Blair and Vinod Khosla see a big future for Congenra, a solar co-generation (producing both power and heat) company formed just 15 months ago with a scant $10 million of funding. With five times more energy production than photovoltaic technologies, Cogenera’s system may help traditional investors discover that the economics of clean energy are …
This 3D holey-structured metamaterial can improve the resolution of sonagraphy by a factor of 50, promising better picture quality for ultrasound imaging as well as sonar.

1. The operator of the Monju fast-breeder reactor in Tsuruga, Fukui Prefecture, asked the prefectural government Tuesday to start talks on restarting possibly by the end of March the prototype reactor. The Monju prototype fast reactor (FBR) in Japan has completed a government-mandated procedure to ensure the reactor is safe to restart following a sodium …
