Scientists create world's first molecular transistor

Scientists at Liverpool University have demonstrated the first transistor constructed from a single molecule, in this case a benzene molecule between gold contacts. They were able to control the current passing through the molecule by using voltage applied across the molecule to change its energy state. The researchers stress that this simply proves that it can be done and is not viable for constructing a "molecular computer".

CBC News - Technology & Science - Better airport scanners delayed by privacy fears

It is believed by some that millimetre wave and backscatter X-ray machines might have foiled the Christmas Day bombing attempt, but implementation of these machines is hampered primarily by concerns about privacy arising from the fact that these machines are able to show body contours under clothing with a high degree of clarity. Where they have been implemented, passengers have been given the option of using the machines or submitting to a pat-down. The US House voted to prohibit the use of these devices for primary screening, and the European Union has requested more study regarding privacy issues before making a final decision.
