Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…

On May 8, all research support professionals of the Leiden Research Support Network were welcomed at the Faculty of Archaeology for an inspiring event.

PhD candidate Jiangnan Ding explores how you can design a thick slab of rubber in a way that it might act as a mechanical computer bit. This so-called mechanical metamaterial is pushed in a specific way to change its shape. ‘With a very simple material, we might be able to do simple calculations in…

Martin van Hecke and Lennard Kwakernaak (Leiden university and AMOLF) develop a mechanical metamterial that can count to ten in their research.

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.’

Martin van Hecke en Anne Meeussen publiceren in het tijdschrift Nature over mechanische metamaterialen. Ze hebben een nieuwe klasse multistabiele materialen ontdekt. Dit is gebaseerd op ribbeltjes plastic.

On 22 September, LUCSoR alumnus Bas van Rijn successfully defended his PhD dissertation entitled “The Experimental Culture of Afterlife Research: Attempts by Spiritual Animal Magnetizers to Prove Life after Death” at Universität Bern, Switzerland. The PhD project was part of the of SNF research project…

This year, an NWO PhD in the Humanities grant went to Mink van IJzendoorn, enabling him to investigate the disappearance of amphorae. ‘We take means of packaging and shipment for granted, but they are deeply ingrained in our daily lives; they are crucial.’

An archaeologist as a modern-day shaman. An unexpected comparison Professor by Special Appointment of Public Archaeology Luc Amkreutz will make in his inaugural lecture.

Martina Huber, Jacqueline Labra Munoz research Alzheimer's disease. They study ferritine, iron storage in the brain. An inbalance of iron could play a role in this form of dementia.

White clouds of ice-cold gas flowing across the floor. Magical, but be careful not to freeze your fingers off. We are of course talking about liquid nitrogen and helium. You may have seen the spectacular Freezing Physics science show by the student organisation Rino. But did you know that this commodity…

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

An all-optical transistor, a molecule-sized sensor and a new kind of single-photon source for quantum communication. All dreamed applications of fundamental physics that are one step closer thanks to Robert Smit. On 12 June, he defended his PhD thesis with distinction.

On Monday 26 February the terrible news reached us that our gifted former Egyptology student – and former student assistant at the Leids Papyrologisch Instituut – Juan Archidona Ramírez had succumbed to cancer.

Four FSW researchers received good news at the end of 2025: they will receive an NWO-XS grant this year.

Lecture

Cancer research generates massive amounts of data, but traditional tools often fail to fully harness their potential. How can we unlock this data to provide better treatments for cancer patients? PhD candidate Marina Gorostiola González explored this by using advanced data analysis techniques to guide…

Who is the real creator when a musician uses AI? This was the burning question for Adam Lukawski, himself a composer. During a fascinating premiere at Amare, The Hague’s cultural hub, he demonstrated what cocreation sounds like.

Using 2D materials, physics student Romme van der Kemp developed a nanochip that is extremely small ánd scalable. This is needed to make all kinds of technologies better, faster and smaller. He has been nominated for the FWN Young Talent Award 2023 for his research.

How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

In the space of seven weeks, the staff of the LUMC and Leiden University have left home more than 35,000 times for a short walk, or an Ommetje as it is known. Healthy University Leiden launched the Ommetje walking challenge to encourage its staff to adopt a healthy lifestyle. Thus far this has resulted…

During her lecture, Professor Annelou van Gijn explored user-wear analysis and experimental archaeology, showing details about past human life.

Leiden researchers Fenneke Sysling and Joris van der Voet will be admitted to the Royal Netherlands Academy of Arts and Sciences’ The Young Academy.

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 consortium of research infrastructures focused on water quality has received €4.18 million in funding from the Dutch Research Council (NWO). This grant will support the transformation of outdoor laboratories at Leiden University, NIOO-KNAW, Radboud University, and Wageningen University & Research…

We are pleased to announce a call for papers for a conference focused on ethical practices in medical research and treatment in the colonial and postcolonial context.

On the university’s birthday, professors teach a class of 10 and 11-year-olds during Meet the Professor. The professors were bombarded with questions.

‘Jelena Prokic, university lecturer and researcher at the Leiden University Centre for Digital Humanities, will be preparing students for the challenges and opportunities of the digital world. In September, six modules will start on subjects such as statistics and digitally searching through texts.…

This year's Nobel Prize in Physics goes to quantum physics research. The prize will be awarded on December 10 in Stockholm. Physicist Bas Hensen explains why this is important and how his research in Leiden relates to it.

The prestigious journal Science Translational Medicine has published a study by researchers from the Institute of Biology Leiden (IBL) on a potent new antibiotic that can overcome resistance. ‘The idea was to tweak the original antibiotic and create a next-generation drug’, says Nathaniel Martin, professor…

Parents’ talk about new stimuli such as persons or objects strongly affects how avoidant or fearful their child will react. No stronger effect was found when parents had an anxiety disorder or in children with fearful temperaments. Publication by a team of Leiden psychologists in 'Clinical Child and…

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.
