Nobel salutes switching brains on with light. Remember 1949?
The Nobel Foundation says December's standing ovation for Karl Deisseroth, Peter Hegemann and Georg Nagel will be delivered by lighting cue, and nobody may touch the controls.
The 2026 Nobel prize in medicine went to Deisseroth, Hegemann and Nagel for optogenetics, the art of switching neurons on with light. The Nobel Foundation has responded by announcing the December ovation will be triggered by a lamp, and posting a guard on the Blue Hall dimmer switch. Magnus Worldweary has seen the brain solved before.
A dimmer switch in Stockholm City Hall now has a man with a gun standing next to it. He arrived on Friday, shortly after the Nobel Assembly announced that this year's medicine prize goes to three scientists who learned to switch brain cells on and off with light. The switch controls the chandeliers in the Blue Hall, where the banquet is held. It has never before needed protection.
Karl Deisseroth, Peter Hegemann and Georg Nagel share 12m Swedish kronor for their work on light-gated ion channels and the field it spawned, optogenetics. Put simply, they took a light-sensitive protein from pond algae and put it into neurons, so that a blue beam makes the cell fire. The Guardian has the full citation. The algae were not consulted, which is how these things usually begin.
Within hours the Nobel Foundation confirmed what the guard implied. December's standing ovation will be "delivered optogenetically". Guests will not be asked to clap. The lights will do it for them.
"Applause has been unreliable since 1901," said Ingrid Hallenborg, the foundation's head of banquet protocol. "Some years it goes on too long. Some years the economics laureate gets more than the chemist, which is unfair to everyone, including the economist. Now we have a cue."
The plan, as described to reporters, is simple. At the climax of the medicine speech a blue lamp above the top table will flash for nine seconds. The hall will rise. Hallenborg declined to explain how a chandelier will reach anyone's ion channels through a dinner jacket, and said that was "a question for the laureates".
I have sat through a great many evenings where someone announced that the brain had finally been solved. The furniture changes. The speech does not.
In 1949 this same assembly gave this same prize to the man who invented the lobotomy. The citation praised its therapeutic value. The method involved drilling into the skull with enormous confidence, and it was celebrated in roughly the same hall with roughly the same wine. One year earlier the assembly had cheered DDT.
Then there is 1784, when a royal commission in Paris had to be convened to establish that Franz Mesmer's magnetic tubs did nothing. I would not raise it, except that Mesmer also preferred to dim the lights.
The house electrician is now a diplomat
The man who actually operates the switch is Bengt Åkerlund, who has run the lighting at City Hall for nine years and had, until Friday, never been quoted by anyone. He has been given a new title, Deputy Head of Ceremonial Illumination, and a security pass with a photograph he dislikes.
"I was told the fader is now a medical device," Åkerlund said, standing a regulation distance from it. "I asked whether I need a licence. They said they would get back to me. I have been doing this with my thumb for nine years."
"I was told the fader is now a medical device. I have been doing this with my thumb for nine years."
Not everyone is applauding, which is of course the point. The Swedish Union of Stage Technicians has filed a grievance arguing that if the lights do the clapping, the lights should be paid the banquet rate. The union's spokesman, Olle Brink, described the ovation as "work" and the lamp as "a scab".
A philosopher at Uppsala, Dr Marit Sjöqvist, raised the obvious concern that an audience that applauds on cue cannot be said to approve of anything. "It is not an ovation," she said. "It is weather." She then noted that this described most ovations she had attended, and withdrew the objection.
The three laureates, to their credit, have said nothing about any of this. NPR reports that their work has already let researchers trace circuits for fear, hunger and sleep in mice. That is real, careful, decades-long science. The nonsense arrives afterwards, carried in by people in white tie who think a Nobel is a product launch.
It always does. The radium people meant well too. So did the man with the drill.
Nine seconds, no more
The foundation has set the ovation at exactly nine seconds, on the grounds that anything longer "looks arranged". Hallenborg confirmed that a second, dimmer bulb will handle polite laughter during the economics speech. A third bulb, for genuine surprise, is on back order until the spring.
The guard beside the switch is not permitted to touch it. Asked what he would do if someone else did, he said he would "escalate", and looked at the chandelier for a long time.
The banquet is on 10 December. I shall attend, as I attended all the others, and I shall rise when the light tells me to. One learns, eventually, that it saves time.
