Jveuxdusoleil (I want sun) taps into a key part of Parisian culture: drinks on the terrasse, as many fear the extinction of the bistrot In August, Paris is uncharacteristically quiet as hordes of residents scatter to the country’s beaches and coasts for a yearly month of vacation. Businesses close and the city nearly grinds to a halt. Among those who remain, there is an eternal, quintessentially

Why evolutionary theory should be applied to peacocks, politics, iPhones and quite a lot in between Nobody expected the Spanish Inquisition, but then again no one could have predicted the giraffe, the iPhone or JD Vance. The laws of physics don’t demand them; they all just evolved, expressions of how (for better or worse) things happened to turn out. Ecologist Mark Vellend’s thesis is that to und

After three years of negotiating, talks over a global plastics treaty came to an end in Geneva last week with no agreement in place. So why has it been so difficult to get countries to agree to cut plastic production? Madeleine Finlay hears from Karen McVeigh, a senior reporter for Guardian Seascapes, about a particularly damaging form of plastic pollution causing devastation off the coast of Ker

They helped create the modern world but are dangerously overused. How can we harness them sustainably? In 1954, just a few years after the widespread introduction of antibiotics, doctors were already aware of the problem of resistance. Natural selection meant that using these new medicines gave an advantage to the microbes that could survive the assault – and a treatment that worked today could b
