Three Leiden professors have recently been awarded the most prestigious scientific accolade in the Netherlands: Maria Yazdanbakhsh and Marc Koper have been awarded a Spinoza Prize and Judi Mesman a Stevin Prize. They received their prizes on 13 October.

How can we diagnose the life-threatening condition sepsis in premature babies as quickly and accurately as possible? That is what PhD student Manchu Thangavelu from the Leiden Academic Centre for Drug Research (LACDR) wants to figure out.

Four university medical centres, including the LUMC, are joining forces to increase pandemic preparedness in the Netherlands.

A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

Concrete actions for assessment panels, boosting responsible evaluation

Minims are letters that are made up of short, vertical pen strokes, such as 'm', 'i', 'n' and 'u'. In Gothic script, there is often little distinction between letters composed of minims. Assistant professor of medieval literature Krista Murchison has written an article in History Today on the hidden…

How can Europe lead the way in vaccine development that is fast and for all? To answer this pressing question, Professor of Vaccinology Meta Roestenberg is holding a panel session on 14 July at the EuroScience Open Forum in Leiden.

Ilze Bot wants to reduce the prevalence of cardiovascular diseases. Her research focuses on mast cells, which protect us from infections but can also make us ill.

The European Space Agency (ESA) has published an interim data release from Gaia, the space telescope mapping out the Milky Way in 3D. The first scientific papers published today reveal half a million stars in the Omega Centauri globular cluster, nearly 400 candidate gravitational lensers and the positions…

At the end of the 7th century something curious occurs in Northwestern Europe. Suddenly, people start burying the dead next to their dwellings instead of in communal cemeteries. Professor Frans Theuws recently published a book on this phenomenon. ‘We wanted to know if the study of these farmyard burials…

Large pairs of planets thought to orbit each other without a star, do not exist after all. That conclude Leiden researchers, after extensive computer modelling and simulations. What the double dots seen by the James Webb Space Telescope are, remains a mystery.

ESA’s space telescope Gaia, which maps the Milky Way, completes its active phase of scanning the sky on 15 January. Over the past decade, Gaia has made more than three trillion observations of about two billion stars and other cosmic objects. ‘Gaia is already the discovery machine of the decade,’ Leiden…

A time-lapse of the universe in more detail than ever before: that’s the aim of the NSF–DOE Vera C. Rubin Observatory in Chile, which will unveil its first images of the night sky on 23 June. Researchers at Leiden Observatory have played a major role in making it all possible.

Every Political Science master’s student at Leiden University completes their degree with thesis. The thesis provides students with the opportunity to pursue a topic of their choosing in depth and conduct independent research. It is a demanding task that requires dedication, attention to detail, and…

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.
