Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

Scientists can peer into cells to get a limited view of their activity using microscopes and other tools. However, cells and the molecular events within them are dynamic, and developmental processes, ...

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.
