Researchers describe their tools for probing how the physical shape of the genome affects genes’ function.

Researchers watch the protein condensin in action.

Researchers map learning-induced chromatin alterations in mouse brain cells, and find that many affect autism-associated genes.

New technologies reveal the dynamic changes in mouse and human embryos during the first week after fertilization.

The switch from maternal factors involves dynamic reprogramming of the zygotic genome.

New microscopy techniques reveal that heterochromatin—the condensed, seemingly dormant portions of DNA—is not as dense as scientists once thought.

A test tube-based genome-labeling technique has been brought under the microscope.
