Theoretical physicists have confirmed that it's not just the information coded into our DNA that shapes who we are - it's also the way DNA folds itself that controls which genes are expressed inside our bodies.
That's something biologists have known for years, and they've even been able to figure out some of the proteins responsible for folding up DNA. But now a group of physicists have been able to demonstrate for the first time through simulations how this hidden information controls our evolution.
The researchers have shown that there's more than one way that DNA mutations can affect us: by changing the letters in our DNA, or simply by changing the mechanical cues that arrange the way a strand is folded.
