Kirsten Kanneworff and David Dechant defend their PhD research on quantum physics at Leiden University. Fundamental work with applications in location verification and the financial world.

Living systems scale from unicellular microbes to complex multispecies communities that constantly change over time. Within the theme Development & Disease, we enhance our fundamental understanding of development and homeostasis of living cells and systems. We analyze the normal situation and how stresses…

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…

IBL-researcher Katharina Riebel, together with international collaborators, published a remarkable finding in Nature Communications on the prevalence of female birdsong.

Herman Berkhoudt (former employee of the IBL, then EEW) organized the course, while Merijn de Bakker and Hans Slabbekoorn spoke about the latest insights in their disciplines.

Sasse, van Breen, Spears & Gordijn demonstrated an anger gap in response to sexism which was larger for women than for men and found evidence that expressed anger was associated with instrumental concerns.

Through his project we will unravel the global regulatory networks that control gene expression in Streptomyces bacteria and allow them to properly respond to major changes in the environment; we will then harness this knowledge to activate and identify novel antibiotics

How do dissociative states affect the ability to suppress emotional distraction (in the context of a working memory task) in patients with Borderline Personality Disorder?

When we are in a conversation, how do we know exactly when to respond, and how do we manage to respond so swiftly, yet without interrupting our interlocutors? Can speech melody – in particular utterance final “boundary tones” – help us determine who will speak next, or are these cues too late in the…

What are the genes and molecular mechanisms involved in bacteria-mediated plant drought tolerance?

Cancer is the leading cause of death in the Netherlands, and, with over 100 different types of cancer, it’s not a simple disease. Today, skin, breast, lung, prostate and colon cancer are the most diagnosed forms. Therefore, the discovery and development of new drugs has the ability to significantly…
