When we think of unethical medical experiments, we tend to think first of Nazi Germany. What is less well known is that experiments were also carried out in colonised areas without the explicit consent of the test subject. University lecturer Fenneke Sysling has received a European grant to research…

A special type of mirror to reflect X-rays has more possible applications than space research. Targeted radiation therapy for cancer, for example. Next to his full-time job, physicist David Girou mapped out the possibilities. He will receive his PhD on 14 June.

Campus The Hague gained a new facility. On Thursday 17 February, POPcorner was opened, helping students find their way during their studies and within the university buildings.

Dutch troops, judges and politicians collectively condoned and concealed the systematic use of extreme violence during the Indonesian War of Independence. Historians have now shown how this could happen. ‘It was scandal management rather than prevention,’ says Leiden historian and research leader Gert…

Effectively treating a severe case of pneumonia is often challenging. Identifying the pathogen behind it can be difficult. PhD candidate Ilona den Hartog tried something new: ‘We searched for answers in substances our own body produces.’ PhD defence on 17 September.

Yuchen Lian defended her thesis on AI and language evolution at Leiden University.

With the aid of artificial intelligence (AI), care professionals at the LUMC (Leiden University Medical Center) are able to calculate quickly and accurately whether a coronavirus patient has suffered serious lung damage. They do this by putting a CT scan through the AI software of the CAD4COVID-CT p…

Care robots, medical treatments, deepfakes and self-driving cars all with the aid of artificial intelligence (AI). The BrAInpower exhibition at Rijksmuseum Boerhaave shows spectacular applications of AI and explains how it can make such huge leaps. Bas Haring, Professor of Public Understanding of Science,…

Why use Google Maps when you can also calculate your bike route based on your own data. Statistician and cyclist Alexander Dürre sees statistics in everything around him. He analyses data of soccer games and calculates the possible winners of cycling races. ‘When I have too much time, I apply statistics…

Kai Hebel explains how the 1975 Helsinki Accords shaped European diplomacy and why their spirit remains urgently relevant in an era of renewed geopolitical in the Guardian.

Writing essays, refining grant applications, or creating a new course curriculum—ChatGPT assists students and researchers in these endeavours. What this new technology means for working in academia, was discussion at the fourth Psychology Connected event.

University lecturer Andrew Gawthorpe comments in an article on the Conversation on Trump’s attack on Iran.

Yeast, alpacas, and antibodies. They may seem unrelated, but within the project of the Leiden iGEM students, they come together perfectly. For the international synthetic biology competition iGEM, the team is working on an innovative method to produce nanobodies—a special form of antibodies—using brewer’s…

In an article for The Conversation, University Lecturer Andrew Gawthorpe comments on the recent elections in the United States and what they mean for President Donald Trump’s position.

When is the last time you made a fire? Not light a candle with a match, but an actual fire from scratch. Thousands of years ago, humans already made fire. Archaeologist Andrew Sorensen (Leiden University) explains when and how they did this.

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.

Associate Professor Salvador Santino Regilme comments on Trump’s visit to Beijing on Al Jazeera.

Feeling good doesn’t just lift our mood—it also helps us stay flexible and resilient. A new study by an international team of neuroscientists shows that natural brain opioids released after rewards play a key role in broadening attention, offering fresh insights into stress, cognition, and well-bein…

Alain studies Public Administration and is politically active. He talks about why it is important for young people to be politically active and vote.

Since September, Victor van der Horst is a member of the Faculty Council. Well, not just a member; he is the Chairman! In addition, this master's student in Mathematics also devotes himself to our Faculty in many other ways. 'I'm convinced we need input from all layers to keep improving our Faculty.'…

What started as a call for help in a Facebook group turned into a permanent group of students from the Bachelor's in Russian Studies and the Master's in Russian and Eurasian Studies who regularly help the Ukrainian refugees. They act as the link between the refugees and aid workers at various reception…

Aesthetic attraction plays a big role in orangutans’ mate choice, behavioural biologist and PhD candidate Tom Roth has observed. But to discover just how big that role is, more research is needed into the emotions of the great apes.

A newly opened museum in China appears to be devoted to the origins of the Austronesian-speaking peoples, who some 5000 years ago spread from East Asia across the Pacific, seeding it with a distinctive culture and some 1200 languages. But those displays are also a statement in the long-running dispute…

The Conversation published an article on the oldest dice authored by Aris Politoupolis, Angus Mol and Walter Crist. In this article they discuss how the oldest dice are d2's, or double sided dice comparable to a coin toss. These double sided dice are 12.000 years old and therefore much older then the…

Are you curious about how the human skeleton works? Discover this and more on 3 October in Leiden and on 4 October in The Hague.

The interplay between literature and law is what Frans-Willem Korsten wants to address as a brand-new professor of Literature, Culture and Law. That means doing research, but certainly also teaching. 'The Hague is of crucial importance for the humanities.'

Many traces of the city's slavery history can be found in Leiden but the public isn't always aware of them. The initiators of 'Mapping Slavery in Leiden' want to change this with guided tours and street markers. Representatives of the University and other Leiden institutions will be giving the first…

Police killed Eric Garner 9 years ago (‘I can’t breathe’) when he resisted a search. Now everyone will consent to stops and searches. Law Professor and author Josephine Ross looks to feminism: what police call consent, feminists would call submission. During the lecture on Wednesday 31 May, Josephine…

Psychology students usually only get to meet patients very late in their studies. Therefore, neuroscientists Ineke van der Ham and Judith Schomaker want to research whether students learn more effectively from a virtual experience with a patient with dementia than from a text. Schomaker: 'We have plans…

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,…

Michaël Peyrot has been appointed professor of Comparative Indo-European Linguistics at the Leiden University Centre for Linguistics with retroactive effect from 1 January. He is looking forward to passing on his love for the subject to a new generation of students.

Can we truly connect with each other through video calls? Yes, according to a recent study. Psychologists found our bodies synchronise almost as much in digital conversations as in real life. But this doesn’t mean we should skip in-person meetings altogether, says researcher Fabiola Diana.

In a new Transforming Society article, Salvador Santino Regilme, Associate Professor and Chair of the International Relations Program at Leiden University, critiques the Trump administration’s US–China tariff war as a covert instrument of domestic class warfare.
