A living semiconductor that could sniff out poison gas in a bio-terrorist
attack has been accidentally discovered by researchers in the US and
Northern Ireland. The discovery followed the scientists\' failure to
eliminate some particularly persistant bacteria from computer chip
production lines.

Electronics engineers are giving birth to a new species of space probes that will adapt to harsh environments, heal themselves and even evolve into better, smarter machines.

The dream of teleporting atoms and molecules - and maybe even larger objects - has become a real possibility for the first time. The advance is thanks to physicists who have suggested a method that in theory could be used to "entangle" absolutely any kind of particle.
