Most of us carry a mental picture of DNA in its iconic form – the famous double helix unveiled by Francis Crick and James Watson. But researchers are beginning to develop a new picture of DNA that shows the molecule’s more dynamic side, which is capable of morphing into a large number of comple... Read More
There are more microbes on Earth than there are stars in the universe. They occupy every ecological niche, from deep-sea vents to the human gut. So you'd expect them to be staggeringly diverse. But the latest studies suggest there may be far less variation than thought.
