Jobs Was a Genius; the Movie Not So Much
The movie's producers tried to sum up Jobs's entire professional career in two hours, too many significant parts were left out, and the movie did not accurately show the genius that Jobs was.
Video: Inside the World's Largest Wind Tunnel
Electronics News 8/23/2013
When NASA Ames runs its massive wind tunnels, the surrounding area knows it. Local aircraft are warned of potential updrafts. Electric utilities brace for sudden power draws. And nearby residents are said to hear its 300-knot airflows from miles away.
Slideshow: Robots Get More Thin-Skinned
Engineering Materials 8/22/2013
Robots may be getting more sensitive, due to a breakthrough by engineers at the University of California, Berkeley. An electronic skin made of a sensor network mounted on a substrate of flexible plastic reacts to touch by lighting up.
Researchers Develop Another Potential Battery for Renewable Energy Storage
A research team led by Yi Cui, an associate professor in the Department of Materials Science and Engineering at Stanford, has developed a new lithium-polysulfide flow battery with an energy density of between 170 Wh/kg and 190 Wh/L and a lifespan of up to 2,500 cycles -- results that are high comparatively for similar batteries being designed for renewables.
Top Reasons for the US to Return to Space
Guest Blogs 8/14/2013
Over the years, government and popular support for further space exploration has dwindled, despite its many benefits. So, we've made a list of the top reasons we should continue to explore the outer depths, "to boldly go where no man has gone before."
How to Make Intelligent Carbon-Fiber Composites
Engineering Materials 8/7/2013
German researchers have demonstrated the ability to embed RFID tags with ultra-thin antennas inside carbon-fiber-reinforced composite components such as aircraft wings. The technique is also being investigated for composite structural health monitoring.
The Failed Fuse Fooled Me
Sherlock Ohms 8/7/2013
When checking the truck's wiring system for a faulty brake light, the first guess turned out to be correct -- after trying everything else.
UL Targets Lithium-Ion Battery Fires

Inspired by recent overheating incidents, Underwriters Laboratories has developed a new testing methodology, along with guidelines and standards aimed at making lithium-ion battery applications safer.
FIR Filters Without the Math
Guest Blogs 8/2/2013
Previous columns have described how analog and switched-capacitors filters work and provided a real example of each. Now on to digital filters that process discrete-time digital values, rather than analog signals.
Update: Corning's Paper-Thin, Flexible Glass
Engineering Materials 8/1/2013
Corning's super-thin, 100-micron Willow Glass can be adapted to high-volume, low-cost, roll-to-roll manufacturing processes not previously possible with glass. Corning is helping customers retrofit or build new lines to integrate the material into manufacturing.
Forget doping. Officials at this yearís Tour de France are looking for a very different form of cheating -- electric motors hidden inside the seat tubes of bicycles.
Through my first-hand experience at MEMS Engineer Forum in Japan, itís clear to me that the IoT is real and that the Japanese are amply prepared for it and are executing on it today.
A new fixings and fastening system for assembling structural, load-bearing composite components promises 54% better adhesion, plus less weight and better mechanical performance than current composite fixing designs.
A cross-disciplinary team of scientists at Harvard University have invented a bionic leaf that can turn solar energy into fuel.
Following in the tracks of the fabled rocket plane programs of the 1940s, NASA engineers are now laying the plans for a new twist on the future of aviation -- a battery-powered airplane.
