Successful Huygens test: last before separation
ESA's Huygens probe, now orbiting Saturn on board the NASA/ESA/ASI Cassini spacecraft, is in good health and successfully passed its sixteenth 'In-Flight Checkout' on 23 November 2004. This in-flight checkout procedure was the last one planned before separation of the Huygens probe from Cassini in December this year. The preliminary analysis of... view more... (2004-11-23)

On chip separation: large molecules pass the speed camera first
What molecule or particle passes the finishline first? A good way to split a fluid sample into its separate parts is: organize a contest in a micro-channel. The largest parts will pass the optical detector first, the smaller ones follow at short distance. This principle of 'hydrodynamic chromatography' is now also possible on a chip. 'On-chip'... view more... (2002-12-10)
