Since the top-rating shows like CSI so frequently rely on DNA to solve many of the deaths, I find it curious that many viewers are may not recognise how easily DNA results may be incorrect.
Some aussie Slashdot'ers may have seen a Four Corners episode regarding DNA results putting the wrong people behind bars.
There are many sites on the web which relate to DIY PCR machines (polymerase chain reaction) to 'photocopy' amounts of DNA which can be used to overlay any other DNA at a crime scene.
How long until we see spam mail selling us someone elses DNA for 'evil' purposes?
Solid state has pretty much taken over AM broadcasting at the 50 kW level and lower.
FM broadcasting is largely dominated by vacuum tubes, but solid state is starting to make inroads at lower power levels.
Tube RF amplifiers have an advantage of handling more power, quite simply due to physics. To do the same in solid state, you need to parallel/gang transistors together.

Pity Yamaha can't put the same effort into making their bikes pick up some moto-GP points. Perhaps if there were a paper moto-GP, we'd have a chance!
Now I know where all the R&D fellas are. In the lunchroom with their clag/glue and scissors.
