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 ...

New findings provide details about the hidden organization of the cytoplasm, showing it makes a big difference where in that cellular broth that messenger RNA (mRNA) get translated into proteins. The ...

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 ...

All living organisms are made of cells, which are the smallest unit of life. Plants and animals have up to trillions of cells that work together to produce ever more intricate organization and ...
