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.’

‘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…

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…

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.

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.

A suitcase covered with stickers from various universities, containing a quantum light source. Since April 2024, this suitcase has been visiting scientists in Europe researching single photons: the smallest possible quantity of light. The suitcase, also called ‘Q-torch’, travels from lab to lab like…

We want FGGA to become a place where everyone feels welcome, at ease, and included. The outcomes of last year's personnel monitor and D&I survey show that we are not quite there yet.

Meijerslezing, Meijersprijzen en Van Wersch springplankprijs en Nieuwjaarsreceptie 2024

De studentassessor: één student die als lid van het faculteitsbestuur aanschuift bij alle belangrijke overleggen en projecten. Zo wordt de student, een van de belangrijkste doelgroepen, vertegenwoordigd bij bestuurlijke besluitvorming. Assessor Julie Külsen draagt volgend collegejaar per 1 september…

During the meeting on 26 February with the future users of Aleida Nijland, design agency Studio Linse presented the interior design. The design is based on earlier input from users, and focuses on functionality, comfort and a future-proof working environment. The interior has been designed to be a pleasant,…

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…

In 2011, the Udhruh Archaeological Project was launched, bringing together teams of Jordanian and Dutch archaeologists to investigate the region and reconstruct ancient water harvesting techniques in the extremely arid landscape of Udhruh. Access to fresh water remains one of the most pressing global…

There are a number of scholarships available for research and internships abroad.

Writing with Light Magazine. Issue no.1 is now available for download as a open access pdf/interactive edition or purchase as limited-run print edition. The magazine builds on our prior work with the journals Cultural Anthropology and Visual Anthropology Review and the editorial collective consists…

Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

If you had something important to write down in ancient times, you would usually write in Greek in the eastern Mediterranean. University lecturer Joanne Stolk has been awarded an ERC grant to explore the kinds of spelling mistakes that were made in these scripts. And, more importantly, what improvements…
