While scientists and artists often learn from bringing their disciplines together, sometimes they can stand back and let the science create the art. These microtubules are bendy 'bone-like' protein structures usually found propping up the cell’s cytoskeleton – but inside this wheel-shaped channel, they appear to dance. Adapting their movement to this new environment, they take on a liquid swirl like noodles in a pan (although 10,000 times smaller). This is a striking example of active matter – the microtubules synchronise themselves into waves of movement similar to collective behaviour seen in swarms and shoals elsewhere in nature. Controlling such fluids may be a way to extract energy from their motion, which may open the way to drive tiny motors and engines inside or outside our cells.
BPoD stands for Biomedical Picture of the Day. Managed by the MRC London Institute of Medical Sciences the website aims to engage everyone, young and old, in the wonders of biomedicine. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
