Genes are active sometimes, and other times they remain dormant for a while. Leiden physicist John van Noort receives an NWO ECHO grant to find out how this happens.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

How did toxin genes evolve from harmless physiological genes?

Leiden molecular cell biologists in the research group of Annemarie Meijer have discovered novel early macrophage-specific genes in zebrafish, including a signal transducer pivotal for the migration of macrophages in the innate immune response to bacterial infection. Their findings were published on…

Dividing Worlds: Tsunamis, Seawalls, and Ontological Politics in Northeast Japan

In September 2021, ACPA PhD Candidate Gabriel Paiuk will premiere a new work titled Sound Theory (The Clouds) as part of the 2021 Gaudeamus Muziekweek Festival. The performance will take place on September 10th, 20:30 at the De Helling (Utrecht, NL).

Leiden Professor of Number Theory Manjul Bhargava has been awarded a Fields Medal, widely regarded as the Nobel Prize for Maths. Bhargava is a professor in Princeton, and since 2010 has also been the holder of the Stieltjes chair in Leiden.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

Conspiracy theories are of all times, and the government should never dismiss them as a fantasy of fools. Certainly not now, when it turned out that authorities made a conspiracy themselves with a journalist threatened with murder. Which proves that the truth is always more insane than you could have…

On Tuesday 15 September 2015, Bart de Smit has been appointed as professor of Algebra and Number Theory at the Mathematical Institute of Leiden University.

When professor Frank Israel graduated at Leiden Observatory some forty years ago, little did he know that one of his theories would be making headlines in 2018 - in the form of a 3D animation on the Internet, no less.

As of 1 June, Floske Spieksma has been appointed Professor at the Mathematical Institute in Leiden. Her field of study is Stochastic Decision-Making. Within this field, researchers develop mathematical techniques to analyse and improve processes within organisations. ‘As a professor, I hope to safeguard…

‘I got into Nature last year, I was nominated for a faculty teaching award and my kids don’t care. But if your simulations get on The Big Bang Theory then that’s something!’ says Huib van Langevelde.

Some people are predisposed to develop cancer. Mutations in genetic material that increase a person’s chances of developing cancer can already be present at birth. Researchers are closely examining these mutations to learn more about how cancer begins to develop.

Can epigenetic changes explain associations between early life stress and health outcomes?

CFP: Two-day PhD/ Research MA masterclass Feminist Theory with and around the work of Prof. dr. Lynne Huffer organised by the OZSW in cooperation with NOG

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…

We aim to understand ion homeostasis in the model eukaryote S. cerevisiae.

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

In this article, Jasmijn Boeken, explores in which ways the defining characteristics of the different zones can be found in the digital sphere.

Climate change is made up, the secret services murdered Pim Fortuyn and JFK, and the moon landing was a fake show. Conspiracy theories are of all times, providing sensation and entertainment, but also unrest and fear. The corona pandemic is new fuel for conspiracy theorists who set fire to 5G masts,…

LCD screens use liquid crystals which have a high degree of order, even though they form a fluid. A new theory maps out the interplay between order, temperature and symmetry. Publication in Physical Review X.

In this project, we will study the genetic and environmental drivers of woodiness and stem lignification at the level of plant‐to‐gene‐to‐molecule.

Following a special donation, the Stichting Pro Juventute foundation is facilitating a new special chair in Educational Theory and Law. Through the chair, Pro Juventute hopes to realise optimum child protection from a coherent legal and educational perspective.

Can a new proteomics workflow be developed to link genes and gene clusters to bioactive molecules, identify novel compounds and enhance the production in the Streptomyces lividans enzyme?

The goal of this book is to place architectural studies, in which people’s interactions with each other and material resources are key, at the crossing of both landscape studies and material culture studies, where it belongs.

What is the origin of educational ideas, e.g., the idea that intervention in infancy has long-lasting effects on development.

What can Robotics and AI bring to archaeological theory and practice? In return, how can archaeology contribute to the developments in robotics and AI research? Colleagues tackled these questions at an event organised by the Faculty of Archaeology and sponsored by SAILS.

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

This dissertation provides a formal description of the relationship between diatopic/diachronic micro-variation and phonologization through analysis of the phonetic/phonological properties of unstressed vowel reduction and vowel insertion in two Northern Italian dialects.

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

This dissertation shows that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof.

The research is aimed at development of an efficient gene targeting method that allows controlled integration of DNA at a preselected site in the Trichoderma genome.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.
