"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.

It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isn’t a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
