The vacuum tube strikes back: NASAs tiny 460GHz vacuum transistor that could one day replace silicon FETs
2014-06-24 14:12:20| Extremetech
Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified light bulbs. This is why early computers like the ENIAC weighed more than 27 tons and consumed more power than a small town. Later, obviously, vacuum tubes would be replaced by probably the greatest invention of all time -- the solid-state transistor -- which would allow for the creation of smaller, faster, cheaper, and more reliable computers. Fast forward to 2014, though, and the humble CMOS field-effect transistor (FET) is starting to show its age. We've pretty much hit the limit on shrinking silicon transistors any further, and they can't operate at speeds much faster than a few gigahertz. Which is why NASA's Ames Research Center is going back to the future with its new vacuum transistor -- a nanometer-scale vacuum tube that, in early testing, has reached speeds of up to 460GHz.

Bluetooth earbuds like Dre's new Powerbeats aren't actually "cordless." They still have a cable running from one bud to the other, which puts a limit on just how tidy and inconspicuous they can be.

Why Did Merck Spend $4 Billion on a Tiny Biotech Firm?
2014-06-14 11:42:27| Biotech - Topix.net
Merck & Co. Inc. has had its sights set on conquering the hepatitis C market for a long time now, and the recovering drugmaker is hoping that a small Cambridge, Massachusetts-based biotech company, Idenix Pharmaceuticals, Inc. , can help it move forward in the race to develop a serious competitor to Gilead Sciences' blockbuster treatment, Sovaldi.
