Discovery of a surprise multitasking gene helps explain how new functions and features evolve

A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.

CRISPR controversy raises questions about gene-editing technique

A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.
Tick tock, tick tock… You can’t hide from the molecular clock.

Explainer: what is the molecular clock?

The molecular clock is helping us deepen our knowledge of evolution and completing the tree of life. But how does it actually work?

Bread, beer and botox: the science behind the 2013 Nobel Prize for medicine

What do bread, beer and botox have in common with this year’s Nobel Prize in Physiology and Medicine? More than you might think. But more on that in a minute. The 2013 Nobel Prize in Physiology or Medicine…

Talk it over: language, uniquely, makes us human

We humans tend to consider ourselves apart from other species. But we’re not really so different. So what makes us unique? I’d say it’s language, though not everyone would agree. Some people insist it’s…
We’re all familiar with the double helix structure so vital to life, but DNA can take other forms. ctbroek/Flickr

Explainer: quadruple-helix DNA

DNA has been called many things: the king of molecules, the blueprint of life, and less excitingly but perhaps more accurately, the genetic code. DNA’s double helix, discovered in 1953 by James Watson…
