No, we're not talking about former Senator Ted Stevens's clumsy description of the Internet; this article from the Stanford School of Medicine Web site instead describes the wildly cool pneumatic tube system used by Stanford Hospital staff to send lab samples around at speeds up to 25 feet (7.6 m) per second - that's roughly 18 miles (30 km) per hour.

Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work.
