Daily Human Digest
Every day, the staff of the Genetic Literacy Project scours the Web for stories on a range of human genetics issues, including gene editing, regulations and bioethics, gene therapy, epigenetics, personal genomics, evolution, ancestry and artificial intelligence. We publish excerpts of those stories and encourage our readers to visit the original publications for the complete stories.

Life insurance and the Genetic Information Nondiscrimination Act
GINA doesn't apply to life, disability, or long-term care insurance. But genetic information could radically change the insurance landscape ...
New technique for simultaneous gene visualization and epigenetic analysis
Techniques exist to visualize specific gene loci within tissue sections. And separate test-tube experiments exist to determine those genes’ epigenetic ...
Whales tan to protect DNA from UV damage, like humans do
In humans, skin pigmentation protects DNA from UV damage. Blue whales react to the sun’s rays similarly, darkening their skin ...
Of humans, primates, and pigs
We humans share a lot of DNA with chimps and other primates, so there’s no real doubt we reside fairly ...
