Prosthetic Arm Controlled by Imagining a Motion

Controlling a prosthetic arm by just imagining a motion may be possible through the work of Mexican scientists at the Centre for Research and Advanced Studies. First, it is necessary to know if there is a memory pattern in the amputee's brain in order to know how the arm moved. The pattern is then translated to instructions for the prosthesis.

NASA Tests Robot Swarms for Autonomous Movement

NASA engineers and interns are testing a group of robots and related software that will show whether it's possible for autonomous machines to scurry about an alien world such as the Moon, searching for and gathering resources just as an ant colony does.

Water Splitter Runs on AAA Battery

Scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.  The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron.In addition to producing hydrogen, the novel water splitter could be used to make chlorine gas and sodium hydroxide, an important industrial chemical. Splitting water to make hydrogen requires no fossil fuels and emits no greenhouse gases. But scientists have yet to develop an affordable, active water splitter with catalysts capable of working at industrial scales."It's been a constant pursuit for decades to make low-cost electrocatalysts with high activity and long durability," said Stanford University Professor Hongjie Dai. "When we found out that a nickel-based catalyst is as effective as platinum, it came as a complete surprise."SourceAlso: Learn about a Proton Exchange Membrane Fuel Cell.

New Laser Technology to Make 2020 Mission to Mars

NASA announced recently that laser technology originally developed at Los Alamos National Laboratory has been selected for its new Mars mission in 2020. SuperCam, which builds upon the successful capabilities demonstrated aboard the Curiosity Rover during NASA’s current Mars Mission, will allow researchers to sample rocks and other targets from a distance using a laser.

Secret of Eumelanin’s Ability to Absorb Broad Spectrum of Light Uncovered

Melanin — and specifically, the form called eumelanin — is the primary pigment that gives humans the coloring of their skin, hair, and eyes. It protects the body from the hazards of ultraviolet and other radiation that can damage cells and lead to skin cancer. But the exact reason why the compound is so effective at blocking such a broad spectrum of sunlight has remained something of a mystery. Now, however, researchers at MIT and other institutions have solved that mystery, potentially opening the way for the development of synthetic materials that could have similar light-blocking properties.

Magnetics Design: Specification, Performance & Economics

An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.

New Circuits Can Function at Temperatures Above 650°F

Engineering researchers at the University of Arkansas have designed integrated circuits that can survive at temperatures greater than 350 degrees Celsius — or roughly 660 degrees Fahrenheit. Their work, funded by the National Science Foundation, will improve the functioning of processors, drivers, controllers and other analog and digital circuits used in power electronics, automobiles and aerospace equipment, all of which must perform at high and often extreme temperatures.
