Five projects with researchers from Leiden University have received a grant from the Dutch Research Council (NWO) to build or upgrade existing research facilities.

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…

Buying chocolates as a sign of love, getting the best deals on Black Friday and putting on a spooky costume for Halloween. In recent years, these holidays and traditions have taken off in the Netherlands, even though they originated on the other side of the ocean. Why are we so excited about American…

In a recent mega-analysis, researchers from Leiden University aimed to clarify the contradictory findings of research into social anxiety disorder. They found that to obtain reliable research results having the largest possible sample size is important. Publication in NeuroImage:Clinical.

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…

As conference organisers, we will use this period to consider how to proceed with the conference. In the most…

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,…

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.

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.

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.

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.

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…

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.

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.

The elderly accept may minor discomforts like stiffer muscles and getting tired more quickly, but they do want to go to their children's birthdays independently. Preventive elderly care helps people with that. The goal is to let people grow old while maintaining their self-reliance and independence…

Kim Stroet is examining how the interaction between teachers and pupils influences pupils’ motivation. ‘Children need to have the feeling that they are in control of their own learning process.’

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

The Journal of Global Slavery (JGS) aims to advance and promote a greater understanding of slavery and post-slavery from comparative, transregional, and/or global perspectives. It especially underscores the global and globalizing nature of slavery in world history.

Social safety is all about creating a supportive community

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…

A step-by-step approach to building confidence in anxiety-prone young children.

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.

Vaccines are an extraordinary category of biopharmaceuticals. They are usually prophylactic and come in many types, from whole bacteria to peptides and nucleic acids. They are very cost effective and almost every human on the planet is vaccinated. The latter mandates that vaccines have to be extremely…

One of the three long-term research interests of our group concerns the Transformation of the Roman World (c AD 450-900).
