In the late 1950s, the CIA’s schemes included using an aerosol to lace the air with LSD in the Havana studio where Fidel Castro made his radio broadcasts, sprinkl­ing Castro’s boots...

A com­puter can play chess to superhuman levels and yet have no concept of what chess is, what place chess has in the world, or even that there is a world. Does this mean that its behaviour isn’t...

When the police bring Sue Black a bag of bones and ask what she makes of them she starts out with four questions: Are they human? Are they of forensic interest? Who was this person? Do they tell us anything...

The violence and ecological collapse of the Anthropocene isn’t a wrong turn, a death spiral by which we have doomed life on Earth, but part of the evolution of Gaia. The next evolutionary stage awaits....

That feeling of similar-but-not-quite is present all through the history of our engagement with the Neanderthals: when we look at them we are looking at a distorted reflection in a mirror. As with a mirror-gazer,...

Until the vaccines arrive – like the cavalry, if you want – it makes sense to be extremely cautious and to suppress transmission of the virus as much as reasonably possible. More stringent...

The record of this year’s wars shows that although these weapons may not provide a decisive edge in combat they excel in self-advertisement, projecting an image of all-seeing omnipotence. Drones...

The more we learn about ourselves and the universe, the more we appreciate that aliens probably won’t just be humans with longer limbs and waving antennae. How do you communicate with a planet-sized...

As a concept, ‘future fossils’ seems a bit reductive, too slickly oppositional, when put to work in such open terrain. What we’re really talking about is stuff. From plastic teaspoons...

It​ starts with bone-shivering chills, which give way to a high fever. The attacks last between six and twelve hours, and end in profuse sweating. When the chills and fever subside, they leave...
