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.

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…

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…

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 Quantitative Clinical Pharmacology group is led by Prof. Dr. Catherijne Knibbe. Her research group aims to define how to adjust a drug dose in special patient populations such as (prematurely born) neonates or children, obese individuals or critically ill patients. Through combining the statistical…

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

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

Stars orbit black holes while jumping up and down. This is the prediction of a theoretical model developed by Leiden physicist Satish Kumar Saravanan, based on Einstein’s theory of relativity. He defends his PhD thesis on July 7th.

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…

In the series 'PhD in the Picture', our PhD students tell us all about their research: what are their findings? How did they do it, and how does their research touch upon hot topics in our society today?

The Multistakeholder Global Governance (MGG) Project is a four-year project which explores how far, and under what circumstances, multistakeholder constructions of global governance operate well, in terms of having capacity, effectiveness, and legitimacy.

For the first time, a group of international and interdisciplinary researchers led by Karline Janmaat and her former MSc Student Chirag Chittar, have tested the several hypotheses on music simultaneously in a modern foraging society during their daily search for tubers – their staple food. They found…

The focus of our theoretical research is understanding the behaviour of soft condensed matter, physical matter which is deformed or structurally altered by thermal fluctuations or small stresses.

On the occasion of the 80th anniversary of the magna carta of civil aviation, the Convention on International Civil Aviation (Chicago Convention 1944), Professor Steven Truxal has written a leading piece for the European Civil Aviation Conference: The Chicago system: a steadfast legal blueprint for…

The Old Observatory houses four historical telescopes. On this page you can learn more about them.

SciSTIP was established on 1 April 2014 as part of the DSI-NRF Centres of Excellence Programme funded by the South Africa’s National Research Foundation (https://www.nrf.ac.za/). SciSTIP is hosted by the Centre for Research on Evaluation, Science and Technology (CREST) at Stellenbosch University and…

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

The D&I Expertise Office works closely with the faculties of Leiden University.

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 International Institute of Air and Space Law is one of the leading international academic research and teaching institutes in the world, specialising in legal and policy issues regarding aviation and space activities in the broadest sense of the word.

Archaeological and related essays on the Jordan Valley in honour of Gerrit van der Kooij on the occasion of his sixty-fifth birthday

LUCDH presents a lunchtime talk once a month on recent research in Digital Humanities & AI. All Leiden University staff and students are welcome to attend in the Digital Lab, Huizinga 0.09 (as well as online). Lectures are announced via the LUCDH Webpages & Newsletter.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

NASA’s telescope SOFIA has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form. Leiden PhD candidate Andrew Barr writes about it in the Astrophysical Journal. The scientists found massive quantities of water and organic…

Researchers from Japan and the Netherlands who were previously involved in the discovery of an exoplanet with huge rings have now calculated that the giant rings may persist more than 100,000 years, as long as the rings orbit in the opposite direction to that of the planet around the star. Their findings…

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

As environmental and ecological changes and their impact become more urgent, demand for Industrial Ecology experts is rising. More and more national and international companies, local and national governments and NGOs are interested in our alumni, who possess the interdisciplinary perspective and skill…

Allosteric modulation has long been recognized as a general and widespread mechanism for the control of protein function. Modulators bind to regulatory sites distinct from the active site on the protein, resulting in conformational changes that may profoundly influence protein function. This concept…

I want to understand the overlap between physical health, mental health, and healthy aging and whether/how stress (behaviorally and biologically) may tie these concepts together.
