Using the James Webb Space Telescope, an international team of researchers, including Leiden Professor of Molecular Astrophysics Ewine van Dishoeck, has discovered a palette of hydrocarbons in a planet-forming disc around a young, low-mass star. The results confirm that discs around very lightweight…

Rainbow flags, funky sounds and drag queen Petty Libel: the very first Canal Pride Leiden has become reality. Leiden University joined the parade with a packed and buzzing boat. ‘The Leideners were really supportive and gave us a great response.’

The book offers different theoretical perspectives to help examine the process of public sector reform. In addition it gives an overview of the major trends in the core areas of the functioning of the public sector.

The recognition that there may be more, so-called allosteric binding sites on a given receptor has also fueled our synthetic efforts. Over the last few years we have focused on many drug targets (adenosine A1, A2A and A3 receptors, the mGlu2 receptor and a classic ‘anti-target’, the hERG channel) to…

Why is there no Northeast Asian security architecture? Assessing the strategic impediments to a stable East Asia. In this article, published in 'The Pacific Review', the authors Wang (Peking University) en Stevens (Leiden University) discuss the reasons why.

Steven Frost defended his thesis on 6 June 2017

In tracing the deeper historical roots of what Xi Jinping contemporarily frames as a “Chinese dream” of “wealth and power,” the article discerns key actors, events, and organizing principles in a long process toward restoring China’s deemed rightful place in the regional system.

The Grotius Centre for International Legal Studies, in collaboration with the ESIL Interest Group on International Criminal Justice and the Journal of International Criminal Justice (JICJ, OUP), is pleased to invite public international scholars, students and practitioners to attend a conference that…

The study of tax law covers the tax system in its full width. It includes domestic, international and European tax law.

On the 14th December 2016, Steven L. Schwarcz, Stanley A. Star Professor of Law and Business at Duke University School of Law gave the thirteenth Hazelhoff Guest Lecture. Professor Schwarcz questioned the often-heard assumption that systemically important financial institutions engage in excessive…

The Old Observatory has a rich history. On this page you will find a short version of the history that took place in the observatory.

Research using the ALMA telescope by scientists including Leiden's John Tobin and Steven Bos has produced the first images of the water snow line within a protoplanetary disc. Publication in Nature on 14 July.

Leiden University has participated in an international study carried out by the CARMENES consortium, which has discovered two small, terrestrial planets around Teegarden’s Star. The planets have masses similar to Earth and their temperatures could be mild enough to sustain liquid water on their surf…

On dinsdag 26 juni 2018, Linlin Sun defended her doctoral thesis ‘International Environmental Obligations and Liabilities in Deep Seabed Mining’. The doctoral research was supervised by Prof. dr. N.J. Schrijver en Prof. dr. E.C.P.D.C. De Brabandere.

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

Scientific research is the main focus of our program. We expect new students to understand what it is and how it works.

At high doses, drug candidate BIA 10-2474 binds not only to the protein that it targets, but to other proteins as well. It thus deactivates proteins that are involved in the metabolism of nerve cells. This is what an international group of researchers from Leiden University and Erasmus MC, among others,…

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

Are there other planets like the earth, and will there also be life? Astronomers study planets around stars other than the sun, with the aim to find out what kind of gasses their atmospheres are made up with.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

What’s the fate of our sun, when in 5 billion years from now our Milky Way will clash with the Andromeda Galaxy? Leiden astronomers have been working on calculations on this collision. They recently gave a visual sneak preview on a big tech conference.
