"I'm all shook up," sang Elvis. Well, the King may have been, but researchers at JILA, a joint institute of the National Institute of Standards & Technology (NIST) and the University of Colorado sure aren't. They're building the "most vibration-free platform on Earth," they say. The structure will measure the ever-evasive thermal noise levels--typically unmeasurable due to the slightest mechanical vibration--as well as perform ground-based detection of low-frequency gravity waves coming from the cosmos. The instrument, designed to cancel out low-frequency, long-wavelength vibrations, uses three nested platforms hung on springs, each with six sensitive movement sensors and non-contact magnetic pushers. High-speed electronics activate the magnetic pushers that move the platform in the opposite direction and cancel the vibrations out. NIST researchers say the instrument can reduce vibration by a factor of nearly a million. The principles behind the project may be applicable to industrial processes like fabrication of ultra-small integrated circuits or diamond turning of super-smooth surfaces.

If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
Robots in films during the 2000s hit the big time; no longer are they the sidekicks of nerdy character actors. Robots we see on the big screen in recent years include Nicole Kidman, Arnold Schwarzenegger, and Eddie Murphy. Top star of the era, Will Smith, takes a spin as a robot investigator in I, Robot. Robots (or androids or cyborgs) are fully mainstream in the 2000s.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
