A research team from IBM and the Georgia Institute of Technology has demonstrated the first silicon-germanium transistor able to operate at frequencies above 500 GHz. Though the record performance was attained at extremely cold temperatures, the results suggest that the upper bound for performance in silicon-germanium devices may be higher than originally expected.

Keeping computer files private requires only the use of a simple encryption program. For criminals or terrorists wanting to conceal their activities, however, attaching an encrypted file to an e-mail message is sure to raise suspicion with law enforcement or government agents monitoring e-mail traffic.

The new football that will be used for the first time in the World Cups opening game on Friday (9 June 2006) is likely to bamboozle goalkeepers at some stage of the tournament, a leading scientist has warned. The Adidas ‘Teamgeist football has just 14 panels - with fewer seams - making its surface ‘smoother than conventional footballs which have a 26 or 32 panel hexagon-based pattern. This makes it aerodynamically closer to a baseball and, when hit with a slow spin, will make the ball less stable, giving it a more unpredictable trajectory in flight.
