There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

In a pair of papers published in the same issue of Cell in 2015, two groups showed that putting physical pressure on cells—by confining them, for instance—causes previously stationary cells to start ...

Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is densely packed with biomolecules like proteins and nucleic acids. How is ...

Scientists discover nuclei aren’t the densest part of the cell. Optical imaging shows a surprising balance that may even ...

(Nanowerk News) Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a ...

The nucleus of a cell is centrally important to an organism. It stores and organizes genetic information, while separating and protecting this very important information from the host of other ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...

Sexual size differences are widespread in biology, yet the "how" behind them often remains vague. We asked a concrete ...
