Lights out, stars on: Daan Roosegaarde on Seeing Stars Leiden
‘What if we switch off all the lights one evening? That idea crossed my mind from time to time. And when I mentioned it to a taxi driver one day, he said: “Oh, you mean: lights out, stars on!” That’s not completely true, of course, because the stars are always on, but his phrase summed up the idea n…

How light and noise pollution disrupt aquatic life
Fish populations in lakes and rivers have declined in recent decades. This is probably due to light and noise pollution. The Horizon Europe grant enables ecologist Hans Slabbekoorn to investigate this and improve the situation for migrating fish. In order to do so, a seven-metre-long swimming tunnel…

Chemotherapy without side effects? It’s possible, with light
Nausea, neurologic pain and hair loss: some of the severe side effects of chemotherapy. Not necessary, biochemist Liyan Zhang showed. Together with Leiden biologists and others, she achieved great results with a drug that is only active in combination with light. Zhang will defend her PhD on 4 July.

This is how physicists use light to build complex structures
Petr Steindl works on quantum dots in microcavities for his PhD research. He manipulates single-photons to create complex structures of light. Applications could include quantum communication and gates for quantum computers.

Research into grave goods sheds new light on traditional roles
New archaeological research into grave goods and skeletal material from the oldest grave field in the Netherlands shows that male-female roles 7,000 words ago were less traditional than was thought. The research was conducted by a multidisciplinary team of researchers led by Archol, the National Museum…

Can humans observe a single particle of light? (And what does that say about our brain?)
Hoping to learn something about the human brain, Leiden researchers are creating a setup to shoot single photons, particles of light, into someone’s eye. ‘The eye is a passageway to the brain.’

Dust cloud from two colliding ice planets dims light of parent star
For the first time, an international group of astronomers have seen the heat glow of two ice giant planets colliding. They could also observe the resultant dust cloud move in front of the parent star several years later. Led by Leiden astronomer Matthew Kenworthy, they monitored the star's brightness…

Dental remains shed light on drug use in 19th century Dutch village
Archaeologist Bjørn Peare Barthold suspected farmers in a doctorless 19th century Dutch village may have been self-medicating to manage pain and disease. By examining the skeletons' dental calculus this hypothesis could be tested. Science Magazine interviewed him about this new technique.

Why do birds flock? Shedding light on collective motions in heterogeneous populations
Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

research into the Humanities Campus: ‘It needs lots of green spaces and light’
Over the past few months, Urban Studies students have been helping to think about the realisation of the Humanities Campus. To test their knowledge in practice, the future urban specialists gave advice on several different aspects, including thermal energy storage and the new central campus building…

Willem van der Does sheds new light on the at times pitch-black history of psychiatry
Piercing through the skull with an ice pick, administering electric shocks without an anaesthetic, or applying leeches to the uterus: these may seem like medieval methods of torture, but they are in fact therapies used in medicine. Willem van der Does writes about all of them in his new book. ‘Physicians…
