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

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

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

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 ...

Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play ...

Metabolism, far from being just a housekeeping function, underlies all changes in cell size and function ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

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 new twist on two-photon polymerization has been used to deliver objects, including lasers and an elephant, directly into ...

Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists at Weill Cornell Medicine have discovered that the nucleolus, long known ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...
