It is theoretically possible that habitable planets exist around pulsars, rotating neutron stars. Such planets must have an enormous atmosphere that convert the deadly X-rays and high energy particles of the pulsar into heat. That is stated in a scientific paper by astronomers Alessandro Patruno and…

Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

Following current regulations regarding the attempts to constrain the effects of the Corona virus outbreak, the University of Leiden has cancelled all physical forms of teaching until 6 April. As conference organisers, we will use this period to consider how to proceed with the conference. In the most…

Dutch astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied “hot Jupiter” HD209458b. The very high-precision observations of carbon monoxide gas show that it is streaming at enormous speed from the extremely hot day side to the cooler night side…

We are extremely proud of our alumni Nandini Paliwal (LLM 2016) and Valentina Vecchio (LLM 2017) for winning first and second place, respectively, for their essays in the EALA Prize this year.

Whilst 2020 has been an unusual and taxing year for colleagues at the Institute of Security and Global Affairs (ISGA), the Institute nevertheless can look back on an impressive range of successful grant applications during the previous year. This impressive result was achieved on top of excellent results…

Wars, climate change and the effects of covid have caused a global decline in children’s well-being. In her inaugural lecture Ann Skelton, Professor of Children’s Rights in a Sustainable World, points to the disastrous effects of multiple interacting crises.

It was already known that social anxiety disorder often affects more than one person in the same family. But research by PhD student Janna Marie Bas-Hoogendam has now shown that there are genetic brain characteristics that are associated with social anxiety. The PhD ceremony will take place on 14 Ja…

The night side of exoplanet WASP-43b, to the surprise of astronomers, does not appear to contain methane. It is likely that extreme winds do not allow enough time for methane to form in detectable amounts. This is the conclusion of an international team of scientists, with Leiden and Amsterdam contributions,…

Jorinde van de Vis wins the For Women in Science Rising Talent-prize for women in science, for her PhD thesis in cosmology and particle physics.

Professor Mirjam de Bruijn will research digital warfare in the North African Sahel with an NWO Open Competition grant. The focus of the research will be on Fulani social networks in war and cultural violence.

A collaboration of physicists and chemists organized the LEELIS conference on new computer chip technology in Amsterdam on 10-11 November. Leiden physicist Joost Frenken is director of the organizing institute ARCNL.

Voters sent a clear signal in the recent Dutch provincial council elections with the 'monster' victory for the Farmer-Citizen Movement (BoerBurgerBeweging, BBB). This sign of ‘social resistance’ has consequences for the policy on nitrogen emissions, according to Geerten Boogaard, Professor of Local…

We are pleased to welcome three new colleagues at the Institute of Security and Global Affairs this month: Andrea Bartolucci, Joana Cook and Silvia D'Amato.

The Netherlands Organisation for Scientific Research NWO allocates nearly € 19.5 million to a Dutch cluster that contributes to the development of an X-ray camera and spectrograph for the new European space telescope Athena. Leiden Observatory is one of the members of the cluster.

Science Magazine has published three back-to-back papers on an important discovery in solid state physics. Leiden physicist Jan Zaanen wrote a Perspective article on the subject in the same issue of 4 March.

Leiden University has been promoting studies on Latin America and the Caribbean for a long time.

The third project, worked on by dr. Rina Knoeff, is a synthesising project directed at studying the Leiden anatomical collections as important parts of ‘public history’. It will use the results of the other projects in order to analyse anatomical collections (their focus, significant silences, audiences,…

This is an Erasmus+ International Credit Mobility project of the Faculty of Humanities with two partners in Uzbekistan.

Every semester, LUCIS invites a scholar to Leiden to provide a lecture series on a topic of their choice. With these lectures, we aim to present state-of-the-art research in Islamic studies to the Leiden academic community and beyond, and to offer students and junior researchers the opportunity to get…

In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…

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.

Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…

Leiden University encourages all its laboratories to obtain LEAF (Laboratory Efficiency Assessment Framework) accreditation.

This project will construct an inventory of possible conceptions of the resistance of the world to scientists’ claims and theories.

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…

Fieldwork

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

European policy affects our lives: from air quality to the frequency of a bus service. Leiden researchers analyse how the European Union functions, how countries apply European policy and whether this policy actually provides solutions and delivers.

This project has two main aims: I. Determine when novelty promotes fear extinction. II. Discover the neurobiological mechanisms underlying these effects.
