DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

Every human face is unique, allowing us to distinguish between individuals. We know little about how facial features are encoded in our DNA, but we may be able to learn more about how our faces ...

Some crimes seemed impossible to solve until genetic genealogy came into play. By analyzing thousands of DNA markers and ...

With a new study in the journal Cell, researchers at Stanford University and Stockholm University have contributed to increased knowledge about gene regulation in human cells. How genes are turned on ...

A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic variants can dramatically alter how fast this expansion happens, sometimes ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

Ancient DNA from Iceland’s first centuries of habitation is forcing historians and geneticists to redraw the map of who arrived on the island, when they came, and how their descendants shaped the ...

Our bodily systems are rife with mutations. In fact, your DNA is mutating right now. These errors, and attempts to repair them, are a key to understanding immune function, aging, and even how heart ...
