Researchers found that aged mice brains show increased micronuclei, which microglia internalize, leading to changes in morphology and gene expression. This process may contribute to age-associated inflammation and vascular dysfunction.

The sequenced genome of Tetrahymena thermophila encodes over 27,000 protein-coding genes and lacks centromeres, shedding light on the single-celled organism's unique biology. The discovery provides a valuable model for studying eukaryotic evolution.
Scientists have found a way for single-celled organisms like Tetrahymena to protect themselves against harmful invaders by co-opting their attributes. This system, discovered by Martin Gorovsky and Kazufumi Mochizuki, helps regulate the cell's genome and prevent disastrous effects from genetic mutations.
