A case against a moratorium on germline gene editing

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?

Having one mental health disorder increases your risks of getting another

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.
New technology means accessing new information from ancient human remains, some which have been in collections for decades. Duckworth Laboratory

Ancient DNA is a powerful tool for studying the past – when archaeologists and geneticists work together

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.
Of more than 500 species of sharks in the world’s oceans, scientists have only sequenced a handful of genomes – most recently, white sharks. Terry Goss/Wikimedia

Sequencing the white shark genome is cool, but for bigger insights we need libraries of genetic data

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.
Evidence shows that the growth of air pollutants – as well as rising temperatures, increased rain and flooding – connect breast cancer with climate change. (Shnutterstock)

As the oceans rise, so do your risks of breast cancer

Most cases of breast cancer are related to environmental causes. When we talk about climate change, we must not forget this part of the story.

Can Seabiscuit’s DNA explain his elite racing ability?

The US went crazy for Seabiscuit when he won his famous 1938 match race against War Admiral. Now researchers are investigating the thoroughbred's DNA to see what made him such an unlikely success.

What causes multiple sclerosis? What we know, don’t know and suspect

Young women are disproportionately affected by multiple sclerosis, a disease where the body attacks the brain, scrambling communication to the rest of the body. Here's what we know about the causes.
