Revolutionary atmospheric-pressure plasma boosts adhesion of polymer films for roll-to-roll solar-cell production
Anthrax targets
A trawl of the genome of the deadly bacterium Bacillus anthracis has revealed a clutch of targets for new drugs to combat an epidemic of anthrax or a biological weapons attack. The targets are all proteins that are found ...

Bacteria with "force sensors"
If connective tissue fibres are under tension, bacteria do not bind to them so well. However, if the fibres are severed and slackened by a cut, the bacterial adhesion molecules recognise this and attach themselves, ...
