Scientists at Leiden University (Netherlands), Stuttgart University (Germany) and Ural Federal University (Russia) have successfully put forward a novel, computed, reaction mechanism that was experimentally tested and show that formaldehyde is formed at much earlier stages in the birthplaces of stars…

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

Victoria Nyst's love for sign language was sparked when she accidentally ended up at a deaf school while studying African linguistics. The university lecturer has since been awarded a Vici grant to research the history of these languages.

The WIIS-NL blog provides articles on gendered international security issues taking a multi-disciplinary approach which includes but is not limited to WIIS focus areas. This blog aims to reach a broad audience of academics, practitioners, students, and interested members of the general public.

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

This book rovides an economic history of Portugal over the course of eight centuries, from 1143 through to 2010 and situates Portugal's economic growth within the context of European development. It also responds to fundamental questions about when, how and why the economy expanded, stagnated or co…

Mathematical biologists from Leiden have developed a model that helps to explain how the spine and vertebrae, among other things, form during embryonic development. The same process, the other way around, plays a key role in cancer metastasis. Publication in iScience.

In this research we have studied how teaching graphing formulas by hand (i.e. sketching a graph of a formula) could promote grade 11- and 12-students’ symbol sense.

How can video on professional practices in university courses be used in a valid and useful way for assessment and feedback?

The European Law Master’s specialisation distinguishes itself by its broad intra-disciplinary approach, covering institutional, constitutional as well as substantive law of the EU in addition to human rights from an EU perspective.

Nienke van der Marel has been awarded the New Horizons Prize in physics for her pioneering research on planet formation. This prize is given to young, promising researchers in physics or mathematics. The astronomer and her colleagues found the first observational evidence for 'dust traps' in disks around…

Helping first-year students at the Faculty of Governance and Global Affairs find their way in a rapidly changing university world because of Covid-19. That was the goal of the mentor project that has been running since this academic year. At the end of January, the first phase ends and in February new…

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

As a PhD candidate, you are expected to follow certain courses and training programmes in the context of your training as a researcher. The courses and training programmes will help you conduct your research, write your dissertation, develop your career, and gain self-insight. The LACDR PhD training…

Monthly PhD Labs offer COI PhD researchers an opportunity to present their work and receive specific feedback about their projects in a supportive and collegial environment.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

PhD defence

The aim of this workshop is to open up the discussion of textual communities in Late Antiquity and the early Middle Ages, by offering a platform for PhD students from all over the world and from various disciplines to present their own research and discuss it with others. Deadline: April 23.

The theme of the anniversary, ‘Ahead of the times’, served as inspiration for the design of the lustrum logo.

In this article, Martin Sievert and Jonas Bruder investigated whether and how administrative burdens influences citizens' perceptions of welfare policies and attitudes towards beneficiaries.

The Senior Teaching Qualification (STQ) is aimed at experienced lecturers who play an active role in the university's educational development.

Here I propose to study the relationship between autonomic pupil-synchronisation and trust, at the behavioural and neural level, and examine a targeted set of possible contextual moderators.

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…

How to contribute to Inter-Section? What does the process look like? We have answered the most frequently asked questions.

Considering the absence of the human performer within a performance installation, the research centres around what is left of the human through traces such as sound or recorded voices, images, videos or movement and gestures. What do we perceive as ‚present‘, once the human is removed from the centre…

ARC (art_research_convergence) is an outreach initiative of Leiden University Academy of Creative and Performing Arts, and the University of the Arts The Hague, for the active communication of artistic research.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

The discovery of a planet far too large for its sun defies models about the formation of solar systems and planets. In a paper in Science, researchers, including Yamila Miguel of Leiden Observatory, report the discovery of a planet more than 13 times heavier than Earth orbiting the ultracool dwarf star…

An international team of scientists, including Xander Tielens of Leiden Observatory, has used space telescope Hubble and the ALMA observatory to show that UV radiation from massive stars can prevent planets from forming. The researchers publish their findings on 1 March in the journal Science.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Fundamental insights into the working of the adolescent brain help lecturers and parents to teach adolescents to function better. Professor Eveline Crone studies executive functions – such as planning and behaviour – in the adolescent brain.

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.
