Anish Kapoor’s blackest black

How much more black could this be? That’s what you’ll find yourself asking if you visit the latest exhibition at London’s Hayward Gallery by British-Indian artist Anish Kapoor. And you might find yourself intoning the immortal answer of Nigel Tufnel, Spinal Tap’s guitarist, as he stared into the sleeve of their “black album”: None. None [ ]

What’s really wrong with ultra-processed foods

It’s a sobering thought that the term “evidence-based medicine” was only coined in 1991 – and that until the 1990s the whole idea was something of a niche pursuit. As science writer Helen Pearson shows in her new book Beyond Belief, the notion that it is worth finding out systematically if an intervention in health [ ]

What Hungary’s election means for science

Historically speaking, Hungarian science has punched above its weight – but often, tellingly, from outside the country. The nuclear physicist Edward Teller, a key architect of the hydrogen bomb, ended up in the US as an exile from the quasi-fascist and antisemitic Horthy regime. The legendary mathematician and physicist John von Neumann had already left [ ]

Is the organism a paradox?

I’m reading The Paradox of the Organism, a set of collected essays on this notion edited by Arvid Ågren and Manus M. Patten. It’s tremendously enlightening. It is also pretty consistent with the story I’d anticipated. I have some sprawling thoughts about the issue and the wider considerations it touches on, and if this were [ ]

Planck’s quanta

This is an extract from the original draft of my forthcoming book The Man Who Broke Reality, a biography of Niels Bohr. Here I explain how Max Planck came up with his quanta. I m putting it up here because I am tired of hearing physicists and others giving a false account of this story. I [ ]

Michael Frayn’s Copenhagen

I just saw the production of Copenhagen at the Hampstead Theatre in London. I haven’t seen it performed since I went to the initial run at the National in 1998, when I believe I reviewed it for Nature (but if so, I can’t find it now). The play is about the meeting between Danish physicist [ ]

What did Artemis do for science?

[Again, very much after the event and written before Trump proposed slashing the NASA budget even more ] The Artemis II moon mission launched by Nasa on April 1 wasn’t without controversy. Few people in the US consider human spaceflight a priority for Nasa, and some scientists feel it distracts (and steals funding) from space science [ ]

Are Palantir perhaps the bad guys?

[I wrote and published this before Karp came out with his technofascist manifesto. It s almost as if he wanted to prove my point.] “Technology is inherently neutral – it’s just a matter of what we do with it.” That sentiment remains disturbingly resilient in the face of many decades of research by historians and social [ ]

On the meningitis outbreak

[Yes, it s very late to the show, but there s always a delay in reposting my columns in The New World ] Meningitis is, among other things, a reminder that many diseases are examples of what the biologist Conrad Waddington called canalisation: the way in which diverse biological causes can produce much the same physiological result. Disease [ ]

Myth and meaning of Henrietta Lacks

The pharmaceutical giant Novartis has reached a legal settlement with the family of Henrietta Lacks, the woman whose cells, taken from the tumour from which she died in 1951 in a Baltimore hospital, have been widely used for biomedical research and drug development. Lacks’ family has been seeking recompense for the uses made of her [ ]
