Why do zebras have their distinctive stripes? Scientists have recently taken up this age-old question, with evidence accumulating that stripes help protect zebras from biting flies and the dangerous diseases they can carry. To really test what’s going on, Tim Caro and Martin How headed to a stable in Somerset where they draped horses in zebra-striped or plain coats and started counting flies. Their findings are groundbreaking.
The way we play computer games can reveal a surprising amount about us. Research shows our in-game actions reflect our real-world values and skills, even if we don’t know we have them. Craig Weightman explains how he’s building a system to help uncover these traits so we can put them to better use.
The economic collapse in Venezuela has been matched by a collapse in basic healthcare and a massive rise in infectious disease. And porous borders threaten to help the spread of diseases like malaria and dengue to neighbouring countries, says Martin Llewellyn. Porous borders are also a boon for criminal gangs, argues Annette Idler, and border communities are paying the price.
The latest defections from the two main UK political parties mean that the recently formed Independent Group now has more MPs than the Liberal Democrats. But it’s still not actually a political party. We have an expert explaining what it needs to do to become one and another on the tactical choices it needs to make if it wants to defy the odds to become an electoral success.

How the zebra got its stripes is not only a just-so story, but an object of scientific inquiry. New research suggests that stripes help zebras evade biting flies and the deadly diseases they carry.
