Can a robot perform a religious ritual just like a monk? And what exactly is a religious ritual? Robots and religion seem to be two different subjects, but according to university lecturer Elpine de Boer, both can make us think about what it means to be human and what we consider to be of value. Together…

These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

Crucial information about research, funding or how university rankings are created is often not freely accessible. The Barcelona Declaration on Open Research Information calls for such information to be made open. Professor Ludo Waltman is one of its initiators. What needs to change?

From predicting Alzheimer’s to the growth of organisms: psychologist Marjolein Fokkema’s algorithms can be used in many disciplines. They also provide inspiration for her songs, theatre shows and life lessons. What drives this rocking researcher?

Goede en actuele data zijn cruciaal om infectieziekten effectief te bestrijden en de volksgezondheid te beschermen. Bijzonder hoogleraar Susan van den Hof en haar team zetten zich in voor betere data-methoden, zodat infectieziekten vroeg worden opgespoord en doeltreffend worden aangepakt.

Astronomers have found complex organic ice outside the Milky Way for the first time. The discovery shows that the building blocks of life could arise early in the universe - and under a variety of conditions, said Leiden astronomer Will Rocha.

AI can help in the online detection of hate speech, but whether the technology would always make the right choices is debatable. Students Tofigh Hasen Nezhad Nisi (Tax Law) and Terra Rolfe (Governance, Economics and Development, LUC) published an article on this topic in Leiden Science Magazine. In…

PhD candidate Julia Wąsala searches for greenhouse gas emissions in satellite data. As a computer scientist, she bridges the gap between computer science and space research. ‘We really can't do this research without collaboration.’

On 3 November 2022, Mariëlle Bruning, Professor of Children and the Law, spoke as an expert on child protection at a roundtable discussion with Dutch Lower House members of the Standing Committee on Justice and Security.

A new graphene-based method could make for faster, cheaper and more accurate DNA sequencing, say a group of Leiden physicists and chemists.

‘I was very happy and honoured that my thesis was recognised as a valuable contribution to the topic of landscape archaeology.’

How to strengthen mutual trust between agencies in the criminal justice system and youth with a migration background or weaker socio-economic position. The Netherlands Science Agenda has awarded 1.5 million euros to a consortium to find out.

Is it possible to measure subtle oscillations caused by dark matter moving through the earth? A Dutch-American physicist team have discovered a new route toward what could be the first-ever measurement of ultralight dark matter. They suspended a microscopic magnet inside a superconducting enclosure,…

Share experiences, gain inspiration or catch up with colleagues: you can do all of these at the Teaching Fair on 30 June. Co-organiser Anna Benjamins explains what the afternoon has in store.

To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

On 11 November Professor of Gastroenterology and Hepatology, Monique van Leerdam will deliver her inaugural lecture entitled, ‘Aiming for Prevention’. Van Leerdam, who specialises in hereditary tumours, was appointed professor in July 2020. In her inaugural lecture she will discuss the importance of…

Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

As an experiment, student Alicia Cai relied solely on AI tools such as ChatGPT and Claude for supervision while writing her thesis. What lessons were learned?
