A neurologist by training, Stefánsson founded Iceland-based deCODE Genetics to explore what the human genome can tell us about disease and our species’ evolution.

Autophagy may keep cell division in check to help protect against cancer-causing DNA damage.

Genetic mutations create lab mice with unusually long and short tails.

Researchers hacked the genetic machinery of E. coli to make them glow and identify proteins linked to cancer.

One lab finds that a similar method produces large genetic deletions when performed in mouse embryos.

The DNA-cutting enzyme used in the technique is not as precisely targeted as scientists had thought, and investors take notice.

Four ways to study mutation rate, a crucial statistic in studies of evolution

Scientists extend the capabilities of the CRISPR-Cas system to include precise manipulations of RNA sequences in human cells.

The deadly fungus Cryptococcus deuterogattii harbors a genetic tweak that propels its mutation rate and allows it to rapidly develop antifungal resistance.
