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, which enables them to cause infections. December 2010
Nanocouriers transport molecular cargo
A train-like system that transports molecular cargo between specific pick-up and delivery zones on a chip has been created by Swiss scientists. The technology could lead to nanoscale assembly lines, or improved self-healing materials, they claim. Developing systems that use nanomotors to move molecular cargos around inside nanoscale devices has become popular recently. As unlike random diffusion, cargo can be moved against a concentration gradient and in contrast to microfluidic devices, an external electrical supply or pump isn’t needed for the transportation. external pageOctober 2010

Close ties with Boston
Last Friday ETH-Zurich President Ralph Eichler travelled to Boston. After a visit to Harvard Medical School, the opening of a new ETH-Zurich alumni chapter and the tenth anniversary of swissnex Boston was also on the agenda.
