Cornell researchers have come up with an interactive prototyping system that prints what you are designing as you design it; the designer can pause anywhere in the process to test, measure and, if necessary, make changes that will be added to the physical model still in the printer.
Physicist Fatima Ebrahimi at the US Department of Energy's Princeton Plasma Physics Laboratory and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations show that the technique, known as coaxial helicity injection, could also benefit tokamaks that use superconducting magnets.
The power grid is aging, overburdened and seeing more faults than ever, according to many. Any of those breaks could easily lead to prolonged power outages or even equipment damage. Binghamton University researchers have proved that the Singular Spectrum Analysis algorithm may be the best tool to help authorities remotely detect and locate power grid faults.
While Michigan's Upper Peninsula is not the sunniest place in the world, solar energy is viable in the region. With new technologies, some people might be inclined to leave the electrical grid. A team from Michigan Technological University looked into the economic viability of grid defection in the Upper Peninsula.
Researchers at the University of California, Riverside and Purdue University are one step closer to developing super strong composite materials, thanks to the mantis shrimp, a small, multicolored marine crustacean that crushes the shells of its prey using a fist-like appendage called a dactyl club. Their latest research, to be published in the journal Advanced Materials, describes for the first time a unique herringbone structure, not previously reported in nature, within the appendage's outer layer.
Scientists from MIPT in collaboration with researchers from a number of other institutes have developed a non-invasive method to diagnose preeclampsia -- a complex condition which occurs during pregnancy.
The key to needed improvements in the quest for better batteries and fuels cells likely lies in the nanoscale, a realm so tiny that the movement of a few atoms or molecules can shift the landscape. A team of American and Chinese researchers has built a new window into this world to help scientists better understand how batteries really work. They describe their nanoscale probe in the Journal of Applied Physics.
Completing a game of 'Super Mario Brothers' can be hard -- very, very hard. That's the conclusion of a new paper from researchers at MIT, the University of Ottawa, and Bard College at Simon's Rock. They show that the problem of solving a level in 'Super Mario Brothers' is as hard as the hardest problems in the 'complexity class' PSPACE.
New fundamental research by UT Dallas physicists may accelerate the drive toward more advanced electronics and more powerful computers. The scientists are investigating materials called topological insulators, whose surface electrical properties are essentially the opposite of the properties inside.
While it's possible to study explosives, sans explosives, new techniques involving high-speed, high-fidelity imaging with optical filtering and signal processing techniques have recently made setting off explosives and capturing the data in real-time a reasonable alternative to developing a new simulation. Researchers report their findings this week in the journal Review of Scientific Instruments.
