A double-expansion technique embeds brain tissue in the absorbent material of diapers to stretch out cells for easier visualization. With expansion microscopy—which stretches out cells so researchers can image their nooks and crannies—scientists used to be able to achieve a resolution of 60 nm. In Nature Methods yesterday (April 17), MIT’s Ed Boyden and colleagues reported that, by subjecting neurons to a double dose of the expansion process, they could achieve a resolution of around 25 nm on conventional microscopes....
