image: Data sonification: hearing the shape of cells. From left to right. (1) Contour of growing pavement cells at three successive days. (2) Contour represented as radius, the distance from the cell center to the cell periphery. (3) The shape spectra is a Fourier Transform of a radius. (4) Each normalized frequency can be represented as the number of equal-length segments dividing cellular outline. This material relates to a paper that appeared in the 28 Feb issue of Science, published by AAAS. The paper, by K.T. Haas at University of Cambridge in Cambridge, UK, and colleagues was titled, "Pectin homogalacturonan nanofilament expansion drives morphogenesis in plant epidermal cells." view more
