Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

Mother Nature has a way of keeping seemingly useless structures around millions of years. Such structures are likely to have a use that is not obvious, although they could also be remnants of the evolutionary past without extant function, or non-functional but harmless byproducts of a different adaptive…
