You may think that your milk-drinking, ice cream-licking days are behind you as you battle the discomfort of lactose intolerance. But there maybe be a way to reverse the situation.
Before you attribute a trait to a famous ancestor like George Washington or Marie Antoinette, you might want to see how much DNA you actually share with these people. It’s not what you thought.
Scientists and ethicists have called for a five-year moratorium on editing human genes that will pass on to future generations. Yes, society needs to figure out how to proceed – but is this the best way?
Mental health is impacted by both genetic and environmental factors. But new research reveals that many mental health disorders may flow from early disturbances in fetal development.
Scientists worldwide are calling for a moratorium on gene editing in germline cells. But what is a germline cell? How does it differ from other cells in our body? Why does it matter if we edit them?
Ancient DNA allows scientists to learn directly from the remains of people from the past. As this new field takes off, researchers are figuring out how to ethically work with ancient samples and each other.
Why do scientists spend so much time and money mapping the DNA of species like white sharks? Single studies may offer insights, but the real payoff comes in comparing many species to each other.

When geneticists create mice with special traits, there is no way to be sure that they will be inherited by the offspring. But a new genetic tool called a gene drive may fix the problem.
Discovering a genetic basis for erectile dysfunction that is linked to Type-2 diabetes will make it easier to identify those at risk – and novel treatments.
An Australian steer named Knickers broke the internet this week. The heavyweight Holstein-Friesian weighs as much as a small car, but genetically speaking he’s within the normal range (just).
