Cell biology

Every second, hundreds to thousands of molecules move through thousands of nuclear pores in each of your cells. A new high-definition view reveals the machine in action.

Innovations in imaging and genetic engineering are coming together to probe the biophysics of cytoplasm inside living animals.

How physically magnifying objects using a key ingredient in diapers has opened an unprecedented view of the microbial world.

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest that neuron-only brain models, such as connectomes, leave out a crucial layer of regulation.

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents flowing through our bodies.

Take a jaunt through a jungle of strange neurons underlying your sense of touch, hundreds of millions of years of animal evolution and the dense neural networks of brains and AIs.

Scientists have identified tubulin structures in primitive Asgard archea that may have been the precursor of our own cellular skeletons.

A small but enthusiastic group of neuroscientists is exhuming overlooked experiments and performing new ones to explore whether cells record past experiences — fundamentally challenging what memory is.

How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger.
