About 40 percent of U.S. trade—some $1.4 trillion a year—passes through the country's 360 ports and waterways. (The rest arrives via truck, rail or plane.) And despite increased protection since 9/11, the U.S. Department of Homeland Security says that these ports remain especially vulnerable to attack from small vessels carrying improvised explosive devices, including radioactive dirty bombs.
That Universal Serial Bus port in your computer is about to get an upgrade. You know, the one where you plug in all your external hard drives, digital cameras, MP3 players, thumb drives, and USB heated-slippers? If you bought your computer any time after the year 2000, it probably came equipped with a USB 2.0 port. However, later this year computers will start shipping that include USB 3.0 ports, which can transmit data up to ten times as fast. Here's what to expect.
To hit a tennis ball with power and precision, contact must be at the "sweet spot," at the center of the racket, where the strings are most responsive. The Prince 03 expands that spot by up to 54 percent by replacing pin-size string holes with half-inch-wide "ports" that allow the strings more room to move upon impact.
