This is a great tip especially if you use gmail and google searches or adsense. Select the Clear Search History button, check off items that you wish to remove, and then click the Clear History button. Remember that even after you remove items, logs and backups will exist on Google's servers.

A machine that "taps" on railroad tracks using laser pulses to check for dangerous internal cracking is being tested by the US Federal Railroad Administration (FRA). The laser pulses create ultrasonic waves that travel through rails at high speed. This means the device can scan for cracks while being pulled along a rail track at up to 70 mph.
