Millions of years before humans invented sonar, bats and toothed whales had mastered the biological version of the same trick – echolocation. By timing the echoes of their calls, one group effortlessly flies through the darkest of skies and the other swims through the murkiest of waters. It’s amazing enough that two such different groups…

In the White Sands National Park of New Mexico, there are three species of small lizard that all share white complexions. In the dark soil of the surrounding landscapes, all three lizards wear coloured coats with an array of hues, stripes and spots. Colours would make them stand out like a beacon among the white…

In science, we don’t often get to talk about male repression, but a new discovery gives us just such a chance. It turns out that ovaries can only remain ovaries by constantly suppressing their ability to become male. Silence a single gene, and adult ovaries turn into testes. That adult tissues can be transformed in…

Revisiting FOXP2 and the origins of language

Today, a new paper published in Nature adds another chapter to the story of FOXP2, a gene with important roles in speech and language. The FOXP2 story is a fascinating tale that I covered in New Scientist last year. It’s one of the pieces I’m proudest of so I’m reprinting it here with kind permission…

When Walt Disney created Mickey Mouse in 1928, he understood the draw that anthropomorphic mice would have. But even Walt’s imagination might have struggled to foresee the events that have just taken place in a German genetics laboratory. There, a group of scientists led by Wolfgang Enard have “humanising” a gene in mice to study…

The success of termites ­and other social insects hinges on their complex social systems, where workers sacrifice the ability to raise their own young in order to serve the colony and its queen – the only individual who reproduces. But this social order can be thrown into chaos by knocking out a single gene, and…

The world of genetics is filled with stories that are as gripping as the plot of any thriller. Take the IRGM gene – its saga, played out over millions of years, has all the makings of a classic drama. Act One: setting the scene. By duplicating and diverging, this gene thrived in the cells of…
