Deciphering Dumba
A HERD of around 40 elephants processes across open grassland in Mozambique’s Gorongosa National Park. Led by a matriarch named Valente, they are headed towards a newly felled tree, a potential food source. The tree is out of sight: perhaps the elephants detected vibrations from the impact through their feet. That’s cool, and the procession…

How does Covid end?
AS Cop26 gets under way in Glasgow this weekend, one collective action problem is taking centre stage against the backdrop of another. Covid-19 has been described as a dress rehearsal for our ability to solve the bigger problem of the climate crisis, so it seems important to point out that the pandemic isn’t over. Instead,…

Epigenetics, the misunderstood science
A little over a decade ago, a clutch of scientific studies was published that seemed to show that survivors of atrocities or disasters such as the Holocaust and the Dutch famine of 1944-45 had passed on the biological scars of those traumatic experiences to their children. The studies caused a sensation, earning their own BBC…

Could whistling shed light on the origins of speech?
FOR centuries, shepherds from the small village of Aas in the French Pyrenees led their sheep and cattle up to mountain pastures for the summer months. To ease the solitude, they would communicate with each other or with the village below in a whistled form of the local Gascon dialect, transmitting and receiving information accurately…

Arms and the virus
LETTING the virus that causes Covid-19 circulate more-or-less freely is dangerous not only because it risks overwhelming hospitals and so endangering lives unnecessarily, but also because it could delay the evolution of the virus to a more benign form and potentially even make it more lethal… This article first appeared in The Guardian on 19 November…

Body consciousness
PARTS of Ann Arbor bring The Truman Show to mind, with their wood-frame houses and white picket fences. Home to the University of Michigan, the city oozes middle-class prosperity and security. So, while doing research there a decade ago, Sarah Garfinkel was shocked to discover that young veterans of wars in Iraq and Afghanistan felt…

Europe’s first farmers
EIGHT thousand years ago small bands of seminomadic hunter-gatherers were the only human beings roaming Europe’s lush, green forests. Archaeological digs in caves and elsewhere have turned up evidence of their Mesolithic technology: flint-tipped tools with which they fished, hunted deer and aurochs (a now extinct species of ox), and gathered wild plants. Many had…
