The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

To what extent does using 360 immersion to a speaking task change the elicited speech, compared to conditions with 2D presentations?

Which intervention technique is more effective in reducing public speaking anxiety in children aged 9 – 12 years, exposure or restructuring cognitions?

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Songbirds as vocal learners learn their songs and song preference from social tutors⁠. Tutor choice for both song and preference learning are important to characterize for understanding individual learning performance and cultural transmission of song⁠.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

This research explores how international organisations responded to the humanitarian and human rights challenges brought about by COVID-19.

Three types of PLCs are studied, varying on the dimension of autonomy of and interdependency between teachers: Joint work, Aid and assistance and Shared practices.

Can SMILE, our multi-component intervention, which combines cognitive-behavioural therapy for insomnia, mindfulness, stress, and lifestyle components, improve sleep quality? Can it also improve mood and quality of life and prevent depression and anxiety in the long term?

Feedback from fellow students on academic writing is as informative as that of teachers. That is one of the findings in Bart Huisman's (ICLON) dissertation. Defence on 12 September.

Water droplets float in a hot pan because of the so-called Leidenfrost effect. Now physicists have discovered a variation: the Elastic Leidenfrost effect. It explains why hydrogel balls jump around on a hot plate making high pitched sounds. Publication in Nature Physics on July 24.

In a virtual game environment, one of the positive effects of anonymity is the absence of one's prejudice toward others, which can give a person the freedom to change and experiment (Bartle, 2003). This project will adopt anonymity to be added to online cross-cultural collaborative learning in higher…

STM scanning experiments on poorly conducting materials are challenging, and can cause a distortion effect. A new model corrects for this effect, allowing physicists to better study materials in their quest to understand unconventional superconductivity. Publication in Physical Review B as Editor’s…

Even if you have a healthy lifestyle, there's a lot to experience and learn during the Healthy University Week, from 26 to 30 October. Health psychologist Andrea Evers is enthusiastic about the week ahead. She tells us about the programme and gives us a taste of her own talk on what the placebo effect…

Plastic pollution is a major environmental issue. Although regulation is being adopted, plastic pollution is still increasing. Effective and strict enforcement is key and NGOs and civilians can be instrumental in this.

Metamaterials have properties that depend on their shape and architecture. Researchers at AMOLF, Leiden University and Tel Aviv University have found a new way of designing these metamaterials and their properties by deliberately incorporating small errors. They publish their results today in Nature…

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

This year, Leiden University celebrates its 444th birthday – and when you’re giving a party, you need great music! Neuropsychologist Rebecca Schaefer agrees. She has been fascinated by music since she was a child, and now she studies how music can make us happy, give us energy or calm us down.

An international, interdisciplinary team of researchers led by Professor of Health Psychology Andrea Evers from Leiden University has now written a first set of guidelines on how to apply the placebo…

Health psychologist Aleksandrina Skvortsova has made clever use of the Pavlov effect to link the ‘cuddle’ hormone oxytocin with the placebo effect. This effect can alter the level of oxytocin in the body, making it possible for people to reduce the amount of medicine they need while still feeling good.…

PhD candidate Dennis Wander searches for the best of both worlds. That is to say: a cancer drug that is effective and also has minimal side effects.
