Researchers' Sweeping Discovery Shows How Kidney Cells Self-Renew

Scientists have discovered a previously unknown 'housekeeping' process in kidney cells that ejects unwanted content, resulting in cells that rejuvenate themselves and remain functioning and healthy. The self-renewal process, which is fundamentally different from how other bodily tissues are thought ...

Butterfly Species' Big Brains Adapted Giving Them a Survival Edge, Study Finds

Heliconius butterflies' brains grew as they adopted a novel foraging behavior, scientists have ...

DNA Element With a Murky Past Is Borrowing Cell's Repair Machinery

Like their viral cousins, retrotransposons have been found borrowing the cell's own machinery to achieve their goals. They hijack a little-known piece of the cell's DNA repair function to close themselves into a ring-like shape and then create a matching double strand. The finding upends 40 years ...

'Lava Lamp' Vesicles Show How Cells Could Self-Organize

The inside of a living cell is crowded with large, complex molecules. New research on how these molecules could spontaneously organize themselves could further our understanding of how cells manage their essential biochemistry in the crowded space. This research may also shed light on how the first ...
