When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

The evolution of a single cellular change into oncology-related pathology is complex, driven by mutations accumulated during cell division, cell to cell interactions, and tissue structure and ...

Scientists have discovered a strange tubular structure inside Profftella, a symbiotic bacterium in the Asian citrus psyllid. These long, helical tubes, filled with ribosomes, show a complexity not ...

Purkinje cells were discovered by Jan Evangelista Purkyně in 1839 and famously illustrated by Santiago Ramón y Cajal in 1899. This Ramón y Cajal drawing shows cerebellar Purkinje cells (A) and granule ...
