Astrocyte diversity across space and time charted in new atlas
When it comes to brain function, neurons get a lot of the glory. But healthy brains depend on the cooperation of many kinds of cells. The most abundant of the brain's non-neuronal cells are astrocytes, star-shaped cells with ...

Pancreatic cancer cells 'speak the language' of organs they will later invade, study reveals
Even as they develop at their primary site, pancreatic cancer cells are already expressing the genes that will determine where they will metastasize, according to new findings from Columbia researchers. The work, published ...

AI uncovers how DNA architecture failures trigger blood cancer
Cancer isn't just about broken genes—it's about broken architecture. Imagine a city where roads suddenly vanish, cutting off neighborhoods from essential services. That's what happens inside cells when the 3D structure ...

Gut bacteria's hidden toxin acts as DNA glue, fueling colorectal cancer risk
Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to colorectal cancer. Because it ...
Order of cancer-driving mutations affects the chance of tumor development, study shows
The order of cancer-driving mutations—genetic changes—plays an important role in whether tumors in the intestine can develop, new research reveals.

Comprehensive map reveals neuronal dendrites in the mouse brain in greater detail
Understanding the shape or morphology of neurons and mapping the tree-like branches via which they receive signals from other cells (i.e., dendrites) is a long-standing objective of neuroscience research. Ultimately, this ...
Ancient genetics and modern pollutants could provide a clue to endometriosis risk
A new study suggests that certain genetic differences, passed down from ancient human ancestors, and exposure to common present-day chemicals could explain why some women are more likely to develop endometriosis.

Backup DNA repair system could be cancer's weak spot
The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix these breaks using highly ...
