The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...
