Scientists can peer into cells to get a limited view of their activity using microscopes and other tools. However, cells and ...

Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

Researchers have developed a way to 3D print custom micrometer-sized structures directly into the interior of living cells.

Scientists have transformed enigmatic cell structures, called vaults, into storage units for messenger-RNA molecules made in ...

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our ...

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.

A hidden structure inside the cell is rewriting how scientists understand leukemia. Beneath the microscope, what looked like disorder turned out to follow a simple physical rule – one that connects ...

Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...
