Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

How did dynastic organization – that it, the employment of non-ruling family members and the development of dynastic traditions and concepts – influence state formation in both Catholic Europe and Muslim West-Asia?

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Together with a large international team of scientists, researchers Peter van Bodegom and Nadia Soudzilovskaia of the Leiden Institute of Environmental Sciences (CML) have created maps of variability in plant trait distribution across the globe. The new maps have been published in Proceedings of the…

In the 16th and 17th centuries, many Northern-Netherlandish artists drew outdoors to train their hands and eyes, and to record landscapes and nature. In her inaugural lecture on 21 March 2022, Yvonne Bleyerveld, Professor by Special Appointment of Art on Paper and Parchment, draws our attention to a…

Accumulation of metals in economy and environment and its associated risks, within the Netherlands and the EU.

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

Description of Effects of glufosinate-ammonium on off crop vegetation.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

On 21 and 22 March 2019 the workshop 'Criptic Identities. Historicizing the identity formation of persons with disabilities across the globe' takes place at the Leiden Institute for History.

On Friday, June 12th, the Europa Institute held its annual PhD Day.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

The European Research Council has awarded a Starting Grant to five early career scientists from Leiden University. They received funding up to 1.5 million euros to further expand on their research subject.

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.

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.

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.

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…

Is polder rice a feasible circular alternative for cows on peatland? A pilot experiment started this week. On May 22nd, researchers from Leiden University and Wageningen University & Research (WUR) planted roughly 3,000 rice plants on the Polderlab near Leiden. The researchers want to test rice as a…

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

Remko Offringa, Associate Professor in Plant Developmental Genetics, and Associate Professor in Molecular Microbiology Arthur Ram both have been appointed as the new Directors of Education at the IBL. Offringa in the role as Director of Education for the Master program and Ram as Director for the Bachelor…

How do plant defense genes get activated?

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

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.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Five researchers from Leiden University have been awarded a Starting Grant by the European Research Council (ERC). This grant of on average 1.5m euros enables researchers who show potential to start their own project, lead a research team and implement their best ideas.

2,240 plant extracts from 1,299 different plant species of Dutch origin. That’s the collection of the Dutch Extract Library, which has recently been transferred to the Institute of Biology Leiden. To plant biologist and contact person for this library Pingtao Ding this is a true treasury. ‘To bring…

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Why do plants produces always produced so many slightly differing metabolites within a particular chemical class?

Identifying natural plant-associated bacteria that provide targeted inhibition of pathogens through the production of antimicrobial peptides.

Optimality in plant properties and processing.

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…

PBDL favors multidisciplinary research. Depending on the problems under investigation, PBDL establishes collaborations between experts from for example molecular genetics, molecular and electro cell physiology, biochemistry, organic chemistry, analytical mathematics, mathematical statistics and computational…

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