Mind Reading Computer
A team from the University of Cambridge is working on a computer that can read minds. With a special camera, the computer observes a person's emotions through facial expressions. The computer does this by observing what the team calls “feature points”-prominent features on the face to measure movements of the head or facial features. In total, there are 24 feature points the computer watches for and 20 movements, regardless of what's on a person's face. Even users who wear glasses or have beards are programmed into its memory. In practice, facial expressions vary from person to person, and as everyone expresses emotions differently, the team still has some work to do. In order for the computer to read minds, it needs thousands of samples to precise identify one's emotions. The group sees several practical applications for the project, including customized advertising. In this scenario, a computer camera combo, maybe even a home webcam, could tailor advertisements specifically to your mood. Other potential uses include aiding those with autism and Asperger's syndrome, who typically have a difficult time interpreting the facial expressions of others. In conjunction with MIT, the developers are working on a special headset version of the system that would communicate the emotions of others to its wearer. They also have plans to develop a system to be installed in cars, which would keep drivers safer on the road.
A flying fish (Cypselurus heterurus) escapes its enemies by launching itself into the air. It bursts through the surface of the sea and glides as far as 100m (330 ft) before splashing back into the sea. A flying fish's “wings” are very enlarged fins. Some species glide using one pair of fins, while others use two.

The drivers for graphics boards, sound cards, and printers are most likely to need an update. On the other hand, drivers of floppy disks, keyboards rarely require updating.
