Optimized tweezers enable precise 3-D manipulations of a cell’s organelles.

Zooming in on the ovarioles of Drosophila could reveal links between muscles, nutrition, and the development of eggs.

When lacking certain enzymes that help plants coordinate cell division, Arabidopsis thaliana cells grow and collect multiple nuclei.

The linkers gather chromosomes together into chromocenters.

Without certain DNA-binding proteins, chromosomes can escape the cell nucleus.

Researchers watch the protein condensin in action.

In the presence of cytosolic DNA, cancer cells activate antiviral pathways that disguise them as immune cells.

Errors in segregation during cell division can lead to inflammation in daughter cells.

Donald Coffey, a longtime professor at Johns Hopkins University, discovered the nuclear matrix within cells and its role in DNA replication.
