In an open letter, 450 leading European researchers from 33 countries have urged European and national governments to strongly cooperate on artificial intelligence , regardless of the Brexit. Leiden professor Holger Hoos is one of the initiators.

Can we improve the treatment of post-traumatic stress disorder (PTSD)? Our young and promising psychologist Rianne de Kleine receives a Veni grant to carry out her research on the treatment of post-traumatic stress.

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…

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).

Lecturers had a week to move their courses online. An enormous challenge because remote teaching definitely wasn’t commonplace at Leiden University. Suzan Verberne, a lecturer and researcher at LIACS, shares her experiences. ‘I tried to do too much in my first week working from home.’

Plants use sunlight to perform photosynthesis, but with too much light they have to dim their activity and protect their cells against photo damage. The protein PsbS acts as a light-stress sensor and plays a key role in this process. Article in Nature’s Scientific Reports.

How do common marmosets combine their calls into sequences and how are their vocalisations influenced by reproductive state?

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…

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Since August 2017, dr. Sarah Schrader is working at the Faculty of Archaeology in the department of Archaeological Sciences. Her expertise is human osteology with a specific focus on the bio-archaeological reconstruction of daily activities. Recently she took over the management of the Osteoarchaeology…

Ariane Briegel wants to use bacteria to detect cancer at an early stage. Together with postdoc Alise Muok, she is developing a method to quickly and cheaply test the urine of patients for the presence of suspicious molecules. They receive a grant of approximately 150,000 euros from the Dutch Cancer…

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…

‘The idea that overweight and obesity are the fault of parents and/or the child, is rubbish.' Roxanna Camfferman, who specialises in child and adolescent studies, explains her proposition. Her PhD dissertation is on the role of upbringing in child obesity.

Mathematical and computational analysis of the dynamics of polar transport of the plant hormone auxin.

Allosteric modulation has long been recognized as a general and widespread mechanism for the control of protein function. Modulators bind to regulatory sites distinct from the active site on the protein, resulting in conformational changes that may profoundly influence protein function. This concept…

‘Stress’ is a state of the organism, in response to a challenge that is hard to adept to. Bodily states are supported by changes in brain activity, but even more so by hormones. Hormones are signaling factors that travel through the blood and in this can way reach many organs to coordinate their activity.…

Here I propose to study the relationship between autonomic pupil-synchronisation and trust, at the behavioural and neural level, and examine a targeted set of possible contextual moderators.

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

PBDL favors multidisciplinary research. Depending on the problems under investigation, PBDL establishes collaborations between experts from for example molecular genetics, molecular and electro cell physiology, biochemistry, organic chemistry, analytical mathematics, mathematical statistics and computational…

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

How is structural and functional brain development related to behavioral change in cognitive-control, impulse regulation, and socio-emotional functioning?

Triple-negative breast cancer (TNBC) constitutes a small subtype (~15%) of breast cancer, but causes the majority of breast cancer-related deaths.

Neurobiological, cognitive and behavioural measurements of normal and abnormal child development.

In a one-hour interview on Dutch radio programme Sleutelstad, Anne-Laura van Harmelen talks about her research into the role friendships in adolescents' well-being, the resilience paradox and the role of social, hormonal and genetic factors in stress-levels and resilience.

‘Stress’ is a state of the organism, in response to a challenge that is hard to adept to. Bodily states are supported by changes in brain activity, but even more so by hormones. Hormones are signaling factors that travel through the blood and in this can way reach many organs to coordinate their activity.…

In this study Lilie Roosman describes the effects of prominence and boundary marking on the temporal and melodic structures of two regional languages of Indonesia, viz. Toba Batak, a stress language, and her native language Betawi Malay, a non-stress language.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

Is blended care a feasible and effective treatment method for social anxiety in adolescence?

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

How do individuals make decisions? What determines the quality of group decisions? When and why do people cooperate with others? How does intergroup competition evolve?

Robotics, using social mechanisms like hormonal modulation, may accelerate our understanding of core sociality principles. By looking at social robotics through an evolutionary lens, we propose this field as a promising framework to investigate the fundamental bricks of sociality from an evolutionary…

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…

Social resilience and security has never been more important. Over the last 2 years, the COVID-19 pandemic has created a considerable disturbance to our personal and social lives. As a result, the general population reports more stress, loneliness and decreased quality of life. At the same time, there…

In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.
