Researchers from UCLA and the Veterans Administration that was investigating how stress affects gastrointestinal function may have found a chemical compound that induces hair growth by blocking a stress-related hormone associated with hair loss — entirely by accident. The astressin-B peptide was responsible for the remarkable hair growth in the bald mice. Just one shot …
James Woodward’s latest paper will be published in Foundations of Physics later this year. It’s about how the Mach Effect can be applied to the Warp Drive and Stargate problem. It covers some new and interesting ground on how to make warp drives and stargates using the M-E’s wormhole and higher terms to generate the …
Researchers from the Centre for Research on Adaptive Nanostructures and Nano-devices (CRANN) at Trinity College Dublin in Ireland and the University of Oxford in the UK have discovered how to split layered materials to give atom thin nano-sheets. Using these sheets, they have created a range of novel two-dimensional nano-materials possessing chemical and electronic properties …
In an interview with Sander Olson, Kevin Parkin, the Deputy Director of the Mission Design Center at NASA Ames, discusses the potential benefits of using microwave power to send payloads to orbit. Microwave power should in theory provide a more efficient, more reliable, and less expensive method than conventional chemical propulsion approaches. Microwave propulsion could …
Stanford researchers have developed the first wireless radios that can send and receive signals at the same time. This immediately makes them twice as fast as existing technology, and with further tweaking will likely lead to even faster and more efficient networks in the future. “Textbooks say you can’t do it,” said Philip Levis, assistant …
Photovoltaic devices (PVs) were fabricated by spray-coating an ink of copper indium diselenide (CIS) nanocrystals as the light-absorbing layer. Without high-temperature post-deposition annealing, PVs were made on glass and plastic substrates with power conversion efficiencies of up to 1.9% and 1.1% IEEE Spectrum covers this work and indicates if it works with 10% efficient, Korgel …
Questek innovations develops nanosteel and alloys of titanium and other materials. Questek computationally designs materials to directly meet user-defined material needs by using our proprietary Materials by Design expertise and technology. They estimate that they reduce development times by as much as 50+% and costs by 70+% as compared to traditional material development methods. The …
The degenerative aging of the immune system is responsible for an enormous burden of disease and disability, from the pain of recurrent Herpes zoster and postherpetic neuralgia, to elevated rates of chronic urinary tract infections, to complications in wounds, pressure sores, ulcers, and surgical incisions. Most prominently, it underlies the meteoric rise in mortality from …
Neutron scattering analysis performed at DOE’s Oak Ridge National Laboratory reveals the lamellar structure of a hydrogen-producing, biohybrid composite material formed by the self-assembly of naturally occurring, light harvesting proteins with polymers. Oak ridge national lab’s sunlight to hydrogen system works. Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a biohybrid …
University of Pennsylvania roboticist Daniel Lee is a researcher at the Penn’s General Robotics Sensing and Perception (GRASP) lab. His students are building robots that compete in robotic soccer leagues, with the ultimate aim being to create a robotic soccer team that can beat the human world cup winners by 2050. Dr. Lee’s team has …
DARPA has new solicitations for 2011 Controlling Cellular Machinery – Vaccines Looking for new ideas about how to discover, design, evolve, assemble and demonstrate the ability to use genetic components, modules and circuits for the development of a highly efficacious nucleic acid based vaccine whose activity can be regulated in vivo by a mammalian host. …
