Taxonomy as a science has accumulated data and knowledge for more than 250 years.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

On Thursday 11 November, Women in International Security Netherlands (WIIS-NL) held its inaugural webinar event on 11 November with four speakers in conjunction with the International Centre for Terrorism (ICCT) and the Chair UN Studies in Peace and Justice at Leiden University.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

Why is the swimming efficiency of the European eel higher than predicted?

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Does a moving hybrid zone leave a genomic footprint?

The new book of Professor of Character evolution and biodiversity Menno Schilthuizen gained a lot of media attention. ‘Darwin comes to town – how the urban jungles drives evolution’ was published in English in February and will be available in Dutch soon.

Hunter-gatherers acquire their food through complex gender-specific foraging techniques for a relatively stable and diverse supply of energy. New research indicates that this specialisation by boys and girls starts at a very young age. Most likely, this enabled the human species to evolve much larger…

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

Which metabolites of sponge are influenced by individual environmental or biological factors?

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

Conference

The European Union has awarded a COFUND grant to a consortium of researchers from the universities of Groningen, Leiden and Eindhoven for a collective fellowship programme called ‘oLife’. The 6 M€ programme, which is co-financed by the participating universities, will recruit and train 18 post-doctoral…

The project Deconstructing Stability aims to improve reconstructions of late prehistoric landscapes and predictive models for the purpose of archaeological heritage management.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

Saskia Gras, PhD graduate from the Dual PhD Center, presents her book on Wednesday 6 June:

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Where did species survive the cold cycles of the current Ice Age?

Can birds - like people- ‘see’ voices and learn how to sing by listening and watching?

What is the function of the insect serosa?

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

The faculty offers several options to deepen and develop your knowledge while being employed. Within the faculty's themes, or in your own working field as a dual PhD candidate, you will be guided to make a next step in your career.

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

How does invasive hybridization affect threatened native species?

How did galaxies form? How did galaxies evolve?

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

Does a snake die when it bites its lip? Why will a mongoose survive a scorpion’s sting, but we humans perish? These questions occupied the minds of toxin-enthusiasts and Master’s students Biology Jory van Thiel and Roel Wouters. They collected information from many sources and published their findings…

Four green research institutes in Leiden are joining forces to integrate evolution and biodiversity research, at local and at the national level. Pivot in this collaboration is Frederic Lens.

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

The programme consists out of three phases: the orientations phase, de pre-PhD phase, and the PhD phase. Each phase has its own characteristics and goals, that are explained below.

I think we should go this way. This way! THIS! WAY!! Making yourself heard in a city can be difficult. That is not only the case for humans, but birds seem to be hindered by urban noise as well. Researcher Hans Slabbekoorn of Leiden University already showed that great tits in Leiden communicate differently…
