Bacterial Clones Show Surprising Individuality
Genetically identical bacteria should all be the same, but in fact, the cells are stubbornly varied individuals.
His Artificial Intelligence Sees Inside Living Cells
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.
Cellular Life, Death and Everything in Between
The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.
Bacterial Complexity Revises Ideas About ‘Which Came First?’
Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.
Biologists Discover Unknown Powers in Mighty Mitochondria
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.
What Defines a Stem Cell? Scientists Rethink the Answer
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.
‘Lava-Lamp’ Proteins May Help Cells Cheat Death
With proteins that reversibly self-assemble into droplets, cells may control their metabolism — and harden themselves against harsh conditions.
In the Nucleus, Genes’ Activity Might Depend on Their Location
Using a new CRISPR-based technique, researchers are examining how the position of DNA within the nucleus affects gene expression and cell function.
In the Ticking of the Embryonic Clock, She Finds Answers
Renee Reijo Pera has spent decades uncovering how the timing of embryonic development contributes to health and disease.
