Epigenetic Manipulations Can Accelerate or Reverse Aging in Mice
Repairing damaged DNA appears to drive aging by causing the loss of epigenetic information, but restoring that information reverses such effects, a study finds.

Buildup of a DNA-repair protein in brain cells spurs shut-eye in the fish, a study finds, and similar results in mice suggest the mechanism is widespread in animals.
Tumor cells missing a critical protein enter neighboring cells to sap their nutrients, then exit those hosts as intact cells, possibly primed to metastasize. Other scholars say it’s too early to know this for sure.
Combining a modified Cas9 enzyme with an unrelated one derived from the immune system of the sea lamprey, researchers demonstrate yet another way to edit a single DNA nucleotide.
