The breakthrough allows researchers to zoom in on RNA (ribonucleic acid) at nanoscale resolution without having to destroy the tissue to remove the RNA for analysis, giving a view of brain tissue that was hitherto out of doctors’ reach. The ability to sequence RNA, a building block of life that u...

This approach offers a unique snapshot of which genes are being expressed in different parts of a cell, and could allow scientists to learn much more about how gene expression is influenced by a cell’s location or its interactions with nearby cells. The technique could also be useful for mappin...
