Hold on to your teeth

Liam Shaw

17 April 2025

The pain​ of toothache arrives long after the damage has been done. The process begins when bacteria in the mouth turn sugars from our food into acid, which etches the tooth’s enamel, allowing the bacteria to penetrate further. Only when they hit the nerve bundles at the tooth’s pulpy core does the sufferer become aware – all too painfully aware – of their predicament. The Stanford Encyclopedia of Philosophy cites toothache as one of two examples of natural evil (the other is hurricanes).

Cardinal Directions

James Vincent

Several years ago​ at a party I met a man who claimed that he navigated London using a compass. Fed up of following directions on his phone, he had bought a handsome, waterproof instrument and fixed . . .

On Compost

Not many​ Edinburgh residents collect beach-cast seaweed, but when a winter storm leaves a strandline deposit on Portobello beach, it feels to me like a gift or a visitation from another world. Seaweed . . .

AI Wars

20 March 2025

When​ DeepSeek announced the release of its chatbot in January, there was widespread bewilderment. How had a Chinese company been able to develop something that could compete with OpenAI’s ChatGPT . . .

Shoring Up SoftBank

When​ I started developing software for the management consulting firms I worked for in the mid-1990s, we still had to connect to the World Wide Web on slow and clunky lines to access our coding work . . .

The Sucker, the Sucker! What’s it like to be an octopus?

Amia Srinivasan, 7 September 2017

Octopuses frustrate the neat evolutionary division between clever vertebrates and simple-minded invertebrates. Their intelligence is like ours, and utterly unlike ours. Octopuses are the closest we can come, on earth, to knowing what it might be like to encounter intelligent aliens.

You Are the Product: It Zucks!

John Lanchester, 17 August 2017

I am scared of Facebook. The company’s ambition, its ruthlessness, and its lack of a moral compass scare me.

In Hyperspace

Fredric Jameson, 10 September 2015

Andrew O’Hagan, 6 March 2014

Diary: After the Oil Spill

Rebecca Solnit, 5 August 2010

The blowout was not only the biggest oil spill in American history by far: it’s a story that touches on everything else – taints everything, like the black glop on sandy beaches, on pelicans, terns, boats, sea turtles, marshlands and dolphins. It’s about climate change, peak oil, the energy future, the American presidency, about corporate power and the corrosive effect of Big Oil on global politics.

Why does it take so long to mend an escalator?

Peter Campbell, 7 March 2002

The descent to the tunnels through which the deep lines run is a tax on the spirit that is paid willingly because it makes it easier to live in an old, tight-packed city. But when the system fails it is strongly resented.

What’s left of Henrietta Lacks? HeLa

Anne Enright, 13 April 2000

I don’t know where I heard of her first: a woman whose cells are bred in culture dishes in labs all over the world; a woman whose cells were so prolific that there is more of her now, in...

The man who mistook his wife for a hat

Oliver Sacks, 19 May 1983

So much for Paris: Climate Overshoot

Dadada: Chasing the Cybercriminals

Vadim Nikitin, 21 November 2024

It’s true that hackers are usually intelligent and highly educated. Yet the success of a hack relies less on mathematical prowess or coding pizzazz than on a keen understanding of human psychology. We...

Story of Eau

How has the widespread assumption of water’s neutrality come about? Who gets to say what water does taste like, how it ought to taste, whether its sensory aspects do or do not testify to its quality?...

On the Nightingale

Mary Wellesley, 6 June 2024

Zzzzzzz: Why do we sleep?
