1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

Dynamic nuclear polarization with paramagnetic agents can enhance nuclear magnetic resonance signals by orders of magnitude. The mechanism of enhancement depends a.o. on the magnetic resonance properties of the agents used. Electron spin relaxation times at NMR relevant magnetic field/microwave frequencies,…

Having encountered a series of shocks that pose an existential threat to our livelihoods, our societies have become increasingly polarized.

Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.

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 PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

Metabolomicshas emerged as an important discipline to study molecular and cellular processes in living cells and organisms with the ultimate aim to obtain an answer to a given biological/clinical question.

Social assistance and minimum income benefits are important instruments as a safeguard against low income and poverty. There have been major developments in minimum income benefits both in developed and developing countries over the last decades. Our study collects several empirical studies regarding…

As of February, Pepijn Reeser steps down as the project director of the Taalmuseum (the Language Museum). Exhibition designer and project manager Tessa Askamp takes over his role.

Despite repeated warnings, John Chau visited the remote Indian island of North Sentinel. His goal: to convert the North Sentinelese to Christianity. These islanders, however, aren't in for outsiders and killed the missionary upon his arrival. Anthropologists Erik de Maaker, Tessa Minter and professor…

Tessa van Schagen and Naomi Sedney know exactly how to combine their Psychology study with top-level sport. Both students are running in the 4 x 100 metre relay at the Olympic Games. Van Schagen: 'Fellow students think it's great that I'm going to Rio.'

Researchers from the Institute of Public Administration and the Institute of Security and Global Affairs at FGGA are launching a new research programme: Governing Polarized Societies (GPS). The programme will focus on the way in which governments are dealing with the increasing polarisation in society.…

Patterned detectors are an existing technology that can be found in almost all color cameras.

That Tessa Schiethart finished her bachelor's degree in International Studies with a thesis on Indonesian women's reasons for veiling was a coincidence. Or so she thought. Six years later, her book Seeing and Being Seen, in which she writes about her life with a wine stain and vision loss, is in the…

With this grant the researchers seek to shed light on the factors which play a role in transmitting jihadist ideas, and explore possible ways to mitigate this transmission.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

The LLRC-committee consists of members representing participating institutes.

In a supplementary decision on 17 May 2022, the Executive Board of Leiden University has concluded that it will publish the titles of seven articles in which there is evidence of malpractice. This concerns a former staff member of the Institute of Psychology. The Executive Board considers it to be in…

On 22 June 2018, Prime Minister Rutte announced that Jaap de Hoop Scheffer, Professor of International Relations and Diplomatic Practices at the Institute of Security and Global Affairs (ISGA), together with former ministers Sybilla Dekker and Winnie Sorgdrager, will become Minister of State.

In this study, Tessa Dool and Thijs Bosker estimate the microplastic uptake of two odontocetes in the Mediterranean Sea and the Norteast Atlantic.

What Determines Perceptions of Bias toward the International Criminal Court? Evidence from Kenya. In this article, published on the website SAGE Journals in the Journal of Conflict Resolution, the authors Geoff Dancy, Yvonne Marie Dutton, Tessa Alleblas, Eamon Aloyo examine the attitude towards international…
