An intense but brief form of lightening known as "red sprites" that occurs high in the atmosphere above large thunderstorms may not be the amorphous blob of light that scientists had first thought. Researchers from Stanford's Very Low Frequency Research Group, who have been studying this phenomenon for several years, now propose that sprites may consist of thousands of fiery streamers, each only a few meters wide. Current observations of sprites, which can be more than 25 miles wide and 25 miles in height, have been made from a considerable distance with high-speed cameras capable of capturing the images of these extremely brief flashes. The best resolution of these images has been several hundred feet, much larger than the size of the streamers that the Stanford model predicts. The group hopes to acquire a special telescope that can capture details in sprites as small as a few feet across. That will allow the scientists to determine if the structure that they have predicted does in fact exist. For more information, contact David F. Salisbury, Stanford News Service, at (650) 725-1944.
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.
