In living cells, regulation of the electrochemical environment is supposed to be managed by ion channels—protein complexes that reside in cell membranes and assume definite shapes. So, it’s surprising ...

An international team of scientists has unveiled the most comprehensive model yet that explains how cells control the flow of materials in and out of their nuclei—solving one of biology's oldest ...

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 ...

As the zebrafish egg cell starts to divide, cytoplasm and yolk granules are segregated. Top row: Bright-field images of the developing zebrafish embryo injected with green micron-sized polystyrene ...

Fruit fly egg cells create miniature tornadoes in order to properly develop and function, and these tornadoes could be widespread in large cells of other species. The cells that make up all living ...
