Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around ...

Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is ...

Nuclei are held together by a quirk of nature, without which there’d be nothing. Two protons next to each other in an atomic nucleus are repelling each other electromagnetically with enough force to ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue ...
