Jeff Fynn-Paul, lecturer at Leiden University’s Institute for History, was recently awarded the European History Quarterly’s 2016 Prize for his article “Occupation, Family, and Inheritance in Fourteenth-Century Barcelona: A Socio-Economic Profile of One of Europe’s Earliest Investing Publics.”

No two pandemics are ever the same. The current coronavirus crisis, for instance, is clearly very different from the deadly plague outbreaks in the 14th and 15th centuries. Can historians learn anything from the coronavirus crisis? And what can we learn at the moment from historians? These are questions…

From the Spanish Flu during WWI to COVID-19: the role of the American government in these Pandemics. Professor Giles Scott-Smith, who together with Dario Fazzi and Gaetano Di Tommaso completed the book project Public Health and the American State, discusses a century of American responses to health…

Lecture

We study how communication can heal and harm when patients are confronted with an illness. Most of our studies focus on serious illnesses such as advanced cancer. Communication lies at the heart of medicine, yet we do not always know which specific communication helps patients. Moreover, many complaints…

Extensive research is being conducted at the Institute of Criminal Law and Criminology on developments in sentencing and punitive measures and how judges and other actors in the criminal justice system reach decisions. Another focus area is how punishments and measures are implemented and the effect…

Internationalisation is an important part of the mission and vision of Leiden University. The Erasmus+ programme, an initiative of the European Commission, makes a substantial contribution to this goal. Erasmus+ provides grants for educational projects with partners within and outside Europe, and facilitates…

And it was a such a success the project will be repeated next year. Fazzi is looking forward to once again offering his students a multicultural…

The American president Trump is considering military intervention in Mexico to get rid of the drug cartels once and for all, but Mexico is not interested in other countries' interventions. According to Jelle van Buuren, Assistant Professor at the Institute of Security and Global Affairs, Trump's much…

An international collaboration, including Leiden physicist and computer scientist Vedran Dunjko, showed that quantum technology can speed-up the learning process of artificial intelligence (AI). To prove this, the physicists and computer scientists used a quantum processor for single photons. Their…

A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

Not taking into account the saturation of drug targets can lead to wrong conclusions about the duration of a drug's action. This is what former PhD candidate Wilbert de Witte writes together with the Leiden professors of pharmacology Meindert Danhof, Piet van der Graaf, and Liesbeth de Lange in Nature…

An international collaboration, including Leiden physicist and computer scientist Vedran Dunjko, showed that quantum technology can speed-up the learning process of artificial intelligence (AI). To prove this, the physicists and computer scientists used a quantum processor for single photons. Their…

The European Research Council has awarded ERC Consolidator Grants to four researchers from Leiden. These grants of up to 2m euros will enable them to continue and expand their research.

It's one of the big cosmology debates: the universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey adapted an independent third measurement method, using the light warping properties of galaxies predicted by Einstein. He published…

In donut-shaped buildings, particle accelerators take super-detailed X-ray images. Yet those images are not good enough to learn how to drive on hydrogen for example. Mathematics PhD student Allard Hendriksen has developed an algorithm that improves the images without having to learn from data from…

Onze samenwerkingsovereenkomsten bieden zowel studenten als medewerkers de kans om een periode in het buitenland te verblijven en zo hun horizon te verbreden. Ook fungeren de overeenkomsten regelmatig als basis voor onderzoeksprojecten of andere samenwerkingsvormen.

Social, Economic and Organisational Psychology focuses on the application of scientific psychological knowledge of social processes within and between groups of people and individuals, in organisations, but also during economic and consumer decisions.

“The first thing to know is…we don’t post anything without approvals,” the lead social media manager at the French Ministry of Foreign Affairs (MFA) explained after I asked about the MFA’s social media processes. [1]

On Friday 13 July, fifty Philippine crocodiles (Crocodylus mindorensis) bred in captivity were released into a lake in the Northern Sierra Madre Natural Park on the northern Philippine island of Luzon. Researchers at Leiden University are hoping this will help speed up the recovery of the crocodile…

Every student learns about science, but those of the Master Honours Class ‘The Academic Life’ went an extra mile. They learned all the ins-and-outs of academia and rounded off this successful lecture series with a final session on evaluating scientific research.

Researchers at Leiden University have made a breakthrough in the study of the hereditary Pompe disease. Together with colleagues in York, they have developed a molecule that binds to the enzyme that is key to the progress of the disease. The findings have been published in ACS Central Science.

Arjen Doelman (Leiden University), Max Rietkerk (Utrecht University), Ehud Meron (Ben-Gurion University of the Negev) and Isla Myers-Smith (University of Edinburgh) received an ERC Synergy grant of 10 million euros with their RESILIENCE project. The researchers will investigate whether and how tipping…

Together, Leiden University Medical Center (LUMC), Leiden University and Philips are one of the 17 AI labs within the ROBUST consortium that will receive support from the Dutch Research Council (NWO). The aim of this collaboration is to use artificial intelligence to speed up MRI scans.

A team of astronomers of Leiden University and the University of Texas (Austin, United States) has discovered a new way to map distant galaxies. They did so by observing the fingerprint of oxygen in a distant galaxy, something that is usually not possible from Earth. The researchers will publish their…

The aim of Plan S – open access in science – is quite right, says the League of European Research Universities (LERU), of which Leiden University is a member. But the proposed implementation plan will cause too much difficulty for researchers and institutes. LERU has therefore come up with ten recommendations…

An international team of astronomers, including Leiden’s Christian Ginski, has discovered previously unobserved structures in a debris disk around a nearby star. Article published in Nature on 8 October.

Astronomers led by Simon Portegies Zwart used simulations to reconstruct how three stars were ejected from the star cluster R136, 60,000 years ago. The analysis reveals that five stars were involved in the event in the Tarantula Nebula.

After almost twenty years the record for the most distant radio galaxy has been broken. A team of astronomers led by Leiden PhD candidate Aayush Saxena has discovered a radio galaxy from the time when the universe was just one billion years old. The galaxy is at a distance of 12 billion light years…

Do all graduates in the humanities pursue a career in education? What does support for incoming students look like in Leiden? And what makes a language study so enjoyable? These and more questions were answered during an information session organised specially for twenty deans from West Brabant.

The Mesoamerican research group 'Time in Intercultural Context: the indigenous calendars of Mexico and Guatemala' funded by the ERC and directed by prof. dr. Maarten Jansen, met up in Mexico from the 13th until the 23rd of February for a field seminar in the states of Tlaxcala and Hidalgo.

The shock wave triggered by one of the five galaxies making up the iconic Stephan’s Quintet appears to be less disruptive than previously thought, with the shock likely being cushioned by dust particles in the surrounding gas. This is according to the analysis of the first scientific observations of…
