Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.
The computer vision scientist Greg Johnson is building systems that can recognize organelles on sight and show the dynamics of living cells more clearly than microscopy can.
The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.
Mitochondria are most famous as sources of metabolic energy. But by splitting and combining, they can also release chemical signals to regulate cell activities, including the generation of neurons.
As it becomes clear that the body’s cells have more diverse regenerative capabilities than expected, experts have had to reconsider their approach to stem cell research.
With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
Renee Reijo Pera has spent decades uncovering how the timing of embryonic development contributes to health and disease.
