Researchers have developed a method that allows power conversion from DC magnetic fields to AC electric voltages using domain wall (DW) motion in ferromagnetic nanowires. The device concept relies on spinmotive force, voltage generation due to magnetization dynamics. Sinusoidal modulation of the nanowire width introduces a periodic potential for a DW, the gradient of which …
1. Japan’s Nuclear Regulation Authority (NRA) revealed on Friday that it may give the approval to restart some of the country’s idled reactors as early as next summer, only after they pass safety inspections beginning in the spring. While only two of Japan’s nuclear reactors are currently online, they were given approval under provisional safety …
A new tissue printer can print cartilage. Bioprinting is an emerging technique used to fabricate viable, 3D tissue constructs through the precise deposition of cells and hydrogels in a layer-by-layer fashion. Despite the ability to mimic the native properties of tissue, printed 3D constructs that are composed of naturally-derived biomaterials still lack structural integrity and …
Smartplanet – the first Navy railgun prototype was developed by military contractor BAE systems and a second railgun was developed by General Atomics. General Atomics recently announced a successful test firing shortly after the delivery of their “Advanced Containment Launcher” to the Naval Surface Warfare Center in Dahlgren, Virgina. Both railguns have proved capable of …
Carl Zimmer who Writes the blog TheLoon, and science fiction and for major magazines talks about Our Viral Future He talks about Ramses V (pharaoh) Died of Smallpox, earliest identified case, determined by examining the mummy Virus – Medawar Virus a piece of bad news wrapped up in a protein Vaccinate with cow pox and …
Researchers at Rice University are designing transparent, two-terminal, three-dimensional computer memories on flexible sheets that show promise for electronics and sophisticated heads-up displays. The technique based on the switching properties of silicon oxide, a breakthrough discovery by Rice in 2008, was reported today in the online journal Nature Communications. The Rice team led by chemist …
Rice University researchers determined in a new study that a process called chemical vapor deposition, which is used industrially to make thin films, could yield a glass that withstands tremendous stress without breaking. Wolynes, a senior scientist with the Center for Theoretical Biological Physics at Rice’s BioScience Research Collaborative, and Wisitsorasak reported their results this …
Phys Org – Northwestern University scientists have developed a thermoelectric material that is the best in the world at converting waste heat to electricity. This is very good news once you realize nearly two-thirds of energy input is lost as waste heat. This is a very environmentally stable material that is expected to convert 15 …

This is a phase 2 NASA NIAC study which could reduce the cost of space telescopes by 250 times. Beyond Hubble class space telescopes could cost a few million instead of a few billion dollars. The mirror costs would be reduced by over 500 times. Photons weigh nothing. Why must even small space telescopes have …
Nearly 3,000 cars, trucks and buses equipped with “connected” Wi-Fi technology to enable vehicles and infrastructure to “talk” to each other in real time to help avoid crashes and improve traffic flow began traversing Ann Arbor’s streets on August 20, 2012 as part of a year-long safety pilot project by the U.S. Department of Transportation. …
