Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

UC Davis researchers tracked the movement of fluorescent particles inside the cells of microscopic worms, providing novel insights into cellular crowding in a multicellular animal. They found that the ...

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 ...

It’s a familiar image, reprinted in countless biology textbooks: an illustration of a typical cell, halved like a grapefruit to reveal its innards. Strands of endoplasmic reticulum encircle a nucleus ...

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 researchers has created the most detailed model yet of how cells regulate traffic through the nuclear pore complex—the gateway between a cell’s nucleus and its cytoplasm. The ...
