An important hormone excreting gland in the human body is the pituitary

The Faculty of Science has presented an infographic with tips and tricks for work stress. The reason for this was the Personnel Monitor 2018, which showed that work pressure is a problem for many employees at the Faculty. ‘It is important to start the discussion about work pressure, and to break the…

Why do some bacteria lose their protective cell wall under the influence of stress? Microbiologist Dennis Claessen of the Institute of Biology Leiden receives a Vici grant of 1.5 million euros from the Dutch Research Council (NWO) to investigate this paradoxical feature.

This study seeks to analyse how job stress could be the result of performing administrative tasks

Thread-like bacteria make cells that no longer have a cell wall under the influence of osmotic stress. A remarkable discovery, since the cell wall serves as a protection barrier for bacteria. It could also help to explain how pathogenic bacteria can hide in our body from our immune system. A team of…

During the ‘intelligent lockdown’ in the Netherlands this spring, the respondents in a Leiden study reported a mild increase in their stress levels. This extra stress could have a negative effect on families, particularly if parents already had psychological problems before the corona crisis.

Children and young people who are victims of emotional abuse at the hands of their parents often report the symptoms of severe post-traumatic stress. These are generally even worse than after other forms of child abuse, such as physical abuse. These are the results of research by Leiden psychologists,…

Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

Disruption to the gut flora can affect your mental health. How could this knowledge be used to prevent stress-related disorders? This is what psychologist Laura Steenbergen will investigate with the aid of a project grant from the Leiden University Fund (LUF) and the Gratama Foundation.

Eiko Fried, associate professor of clinical psychology, comments in Leisure Management on new research showing that consumer smartwatches cannot distinguish between stress and excitement. He stresses these devices are lifestyle gadgets, not medical instruments, and warns consumers against overestimating…

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…

From the effects of hormone fluctuations in women via the interior structure of giant planets to the prehistory of the languages: six Leiden researchers have been awarded a Consolidator Grant by the European Research Council.

Having a chronic somatic condition can result in a variety of impairments in patients’ daily lives, including not only physical complaints such as pain, itch, and fatigue, but also problems of negative mood and impairments in social relationships. Next to disease characteristics, individual difference…

Factors affecting galanthamine production in Narcissus

Is it possible to pharmacologically condition oxytocin responses in healthy individuals and identify the neural circuitry underlying such conditioning?

It often takes longer for women with heart problems to get the right diagnosis. In her Annie Romein-Verschoor Lecture, Professor Hester den Ruijter will talk about how hormones influence the heart and the importance of medical research that focuses specifically on women.

Advanced fluorescence microscopy techniques have revealed how steroid receptors move inside the nucleus. The results were published by a team from Leiden University and the Erasmus Medical Center in Rotterdam, led by IBL-researcher Marcel Schaaf.

Oxidation is a common degradation pathway that affects therapeutic proteins and peptides during production, purification, formulation, transportation, storage and handling of solid and liquid preparations. In the present work we review the scientific literature about structural and biological consequences…

This project has two main aims: I. Determine when novelty promotes fear extinction. II. Discover the neurobiological mechanisms underlying these effects.

Psychologists Marieke Tollenaar, Anne Miers and Esther van den Bos received donations from the Leiden University Fund and Stichting Praesidium Libertatis to take crucial first steps in research projects that may eventually contribute to the well-being of vulnerable youth.

The overarching aim of this theme is to increase our understanding of the mechanisms underlying altered cognitive, affective, and social behavior in relation to mental health problems.

Are you interested in the neurocognitive and biological roots of learning, behaviour and emotions in children? If so, the programme in Applied Neuroscience in Human Development might be the specialisation you are looking for.

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.…

The earth has more than 7 billion inhabitants, all of whom leave behind traces of pollution. However, not all forms of pollution have the same harmful effect. Leiden scientists help determine where we should put our priorities.

The use of the pill, in combination with genetic factors, can influence experimental psychological research in women. More research is needed into the influence of the pill on mood disorders, concludes psychologist Daniëlle Hamstra. PhD defence on 30 September.

Consumer grade smartwatches may not be as accurate as promised when measuring tiredness or stress. That is the conclusion of researchers Björn Siepe and Eiko Fried based on a comparison between smartwatch measurements and self-reports by users.

Psychologist Daphne Tona is one of the first to investigate a small nucleus in the brain stem 'in vivo' in living volunteers. That nucleus is involved in cognitive function and neurological and psychiatric disorders. With this research Tona is further mapping the brain. PhD defence on September 10.

A consortium of researchers from the Leiden Institute of Physics (LION), the Institute of Biology Leiden (IBL), and the Leiden Institute of Chemistry (LIC) received a FOM program grant to develop a novel way of studying individual proteins inside a cell using gold nanorods.

Leiden University is partner of the Netherlands Centre for One Health (NCOH). This initiative brings together leading academic research institutes in the Netherlands in an open innovation network that responds to the theme: One Health. NCOH interviewed Doris van Bergeijk: PhD student of the project…

On Thursday 17 October, Marieke Bos and Anika Bexkens went behind the scenes at the Jeugdjournaal, a Dutch television program that delivers news specifically for children. They talked to the editors-in-chief of Jeugdjournaal about what kind of questions they receive from children and advised how to…

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

Are you a school or university student, and do you feel very anxious before and during exams? Take advantage of these tips by Leiden student psychologists, from how to stop ruminating to how to conquer a black-out.

In mid-March 2020, the global coronavirus outbreak changed everything in the Netherlands. Staying at home as much as possible and the 1.5 metre rule became the standard. One year on, we reflect on the past year with four Leiden Law School ‘insiders’. What kind of year did they have? And what are their…

The Laboratory for Human Osteoarchaeology specialises in the macroscopic and microscopic analysis of human remains. We use cutting edge scientific approaches to address archaeological, historical, and anthropological research questions. In addition to paleopathological, histological, and 3D scanning…
