Autism, Alzheimer’s, and bipolar disorder: can the development of these mental health conditions be influenced by the ketogenic diet? Increasingly, research suggests it might. 'For those it helps, it can be life-changing,' says neuroscientist Eline Dekeyster.

How do you study the growth of microorganisms, the spread of epidemic diseases or the healing of wounds, without actually performing experiments? Daoyi Wang, PhD candidate at the Mathematical Institute, worked on a specific mathematical model that can describe the growth of microorganisms and many other…

Gaan vaders minder werken als andere vaders dat ook doen? Helpt betaald ouderschapsverlof hen om meer op te pakken in het huishouden? Hoe bepalend zijn sociale normen voor verschillen op de arbeidsmarkt? Onderzoeker Max van Lent gaat het uitzoeken.

Software development is probably not the first thing that comes to mind when you think of a sociologist. Three years ago, John Boy began developing his software package Textnets. Because of Corona, he was less able to concentrate on writing scientific research and also setting up the online courses…

The description of a painting directly affects how children look at that artwork. This was discovered by psychologist Francesco Walker in the Rijksmuseum. Another finding presented in his article in Nature - Scientific Reports is that giving children information intended for adults has the same effect…

Not all sustainable business models have the impact they claim, Leiden researcher Levon Amatuni revealed. Car sharing and phone reuse, for example, have a smaller positive effect than previously thought. Amatuni advises people to ‘pay attention to actual changes in their consumption behaviour rather…

This summer, political scientist Thijs Vos received the Kaare Strøm prize for his paper ‘Power or Ideology? What structures legislative voting behaviour in Dutch municipal councils, ideology or coalition-opposition dynamics?' He was awarded the prize during the ECPR summer school on parliaments in F…

Not experiments and lab coats, but computers and artificial intelligence: this year's Nobel Prize in Chemistry went to the inventors of the groundbreaking AI model, AlphaFold. This programme accurately predicts protein structures based on their genetic code—a crucial step in understanding biological…

With great sadness we share the news that Prof. Harold Linnartz passed away suddenly and unexpectedly on Sunday 31 December 2023. We are all in shock, and our thoughts are with his wife and children, other family, and friends. Harold was at the heart of our institute, as a researcher, as a supervisor,…

Three Psychology students will present a poster of their thesis research on Alzheimer’s and dementia at the international conference AAIC Neuroscience Next. ‘I remind myself to recognise - without fear or shame - when I don't know something.’

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…

It’s an important theme at the University and beyond: student well-being. Even before coronavirus, research showed that loneliness and the pressure to succeed were causing particular problems for students, and these problems have only increased since the pandemic. Work is underway to improve the sit…

In the middle of doing research for her master’s thesis, Sara Kalf (24) was hit by a car and got seriously injured. After a long period of rehabilitation and hard work, this week she can finally add her signature to the wall of the Academy Building’s ‘Sweat Room’.

This is a difficult time. Above all, for all those directly involved in this horrible case – unacceptable behaviour by a professor and his removal from the University – the case we went public about on 18 October and that has been reported in the media. This is painful and tough for the complainants…

This Thursday, January 18th 2024, our esteemed colleague Jan Zaanen passed away. Jan was one of our star scientists, larger than life, with an unabashed, boisterous drive for the best of physics at the Institute Lorentz, at the Leiden Institute of Physics and in the full international scientific community.…

Intelligence and National Security is the new specialisation in MSc Crisis and Security Management (CSM). It will start next September 2021. Do you want to know more about this track?

CML grants three Stans Awards each year, known as the best student thesis, best PhD paper and best outreach from the past year. The CML staff nominated students and colleagues and this year’s jury Prof.dr.ing. Jan Willem Erisman and Prof.dr.ir Willie Peijnenburg made the final decision.

A safe haven for students, more bicultural staff and more powers for diversity officers. In a national expert meeting at Campus The Hague, administrators, diversity officers, students and staff discussed urgently needed measures.

In the ‘Educatips’ column, psychology lecturers share their most important insights on teaching. This month: Taarique Debidin thinks making contact with one another is more important than cramming knowledge. ‘I’d get no energy at all from being a formal lecturer.’

Whilst 2020 has been an unusual and taxing year for colleagues at the Institute of Security and Global Affairs (ISGA), the Institute nevertheless can look back on an impressive range of successful grant applications during the previous year. This impressive result was achieved on top of excellent results…

When writing a thesis or paper you must make good use of the insights you have gained during your lectures and studies so far. You should also refer to relevant literature and carry out your own research on the topic.

Personal development, Working effectively

In prehistoric times there was a huge wave of migration, from the steppes in Russia and Ukraine to West Europe. The newcomers’ genes began to dominate. Archaeology research in Leiden into burial mounds in the Veluwe and Utrechtse Heuvelrug areas of the Netherlands yielded this spectacular conclusion.…

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…

Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.
