The OTHER Genome Project That’s Transforming Medicine
You've heard of the Human Genome Project, and how having all that info about our genes could help us treat /tons/ of diseases. But a newer project wants to zoom out a little and use different genetic information to help us solve our...

Did An Ancient Pathogen Reshape Our Cells?
There is one - and only one - group of mammals that doesn’t have alpha-gal: the catarrhine primates, which are the monkeys of Africa and Asia, the apes, and us.

The Genes We Lost Along the Way
Our DNA holds thousands of dead genes and we’ve only just begun to unravel their stories. But one thing is already clear: we’re not just defined by the genes that we’ve gained over the course of our evolution, but also by the genes that...

Our “Junk DNA” Is More Important Than We Once Thought
In the search for the genes that make us human, some of the most important answers were hiding not in the genes themselves, but in what was once considered genomic junk.

The Island of the Last Surviving Mammoths
The Wrangel Island mammoths would end up being the final survivors of a once-widespread genus. In their final years, after having thrived in many parts of the world for millions of years, the very last mammoths that ever lived...

Why Deadly Viral Pandemics Are Becoming More Common
Viruses keep jumping out of nature and into humans and getting us very sick in the process. So why do zoonotic spillovers like SARS-CoV-2 happen, and why are they becoming more frequent? We asked an expert.

What Can You Actually Learn from Your Genome?
Genetic tests can give you advice about what lifestyle, diet, and level of exercise are best for you. But you should take those suggestions with a grain of salt, because, when it comes to our bodies, our genes aren’t so much an open...
