(Figure Presented) Going with the flow: DNA replication by the polymerase chain reaction (PCR) can proceed at a greatly accelerated rate when performed in the presence of a chaotic flow induced by microscale thermal convection (see picture). The consequences of these effects sharply contradict established design rules for chemistry involving coupled flow and reaction. 2011 Wiley-VCH Verlag GmbH & Co. KGaA.
