Five talks will be given during the Leiden Science Family Day: two children's lectures and three lectures for adults. Will you be there ?

Prof. Elizabeth de Lange is concerned with the allocation of resources for the conduct of science towards the goal of best serving the public interest. Also, while she underscores that there is still the need for using animals in drug research, she is concerned about this use, and advocates the use…

S.S. Kolipaka’s thesis questions and investigates the survival prospects of reintroduced tigers and their offspring’s in the human dominated landscape of Panna tiger reserve in India.

New drugs for use as tuberculosis (TB) treatment are needed due to the constrains of classical antibiotics against TB and the rise of antibiotic-resistant strains, making TB a harder and harder disease to treat.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

This PhD subproject concentrates on 16th-century ichthyology and takes Gessner’s Historia piscium (1558) (further HP) as its point of departure and focus.

This project, under the supervision of Prof. Dr. Hans van der Plicht, comprises several studies aimed at the use of isotopes occurring naturally in organic material as tracers for both the climate change and its cultural impact at about 6200 BC. The research will be carried out by the co-applicant at…

What is emotion in human and nonhuman animals? How do emotions get to expression and how do they impact on our interactions, our decisions to trust, distrust or cooperate? Why do we mimic and synchronise affective processes?

Members of the collective explore what it means to be ‘human’, in the past and present, from a range of different perspectives and inter-disciplinary approaches.

What categories exist in the languages of pastoralists? Do these semantic concepts reflect universal or languagespecific tendencies? What (environment? culture?) governs the similarities (or the differences) attested crosslinguistically in cattle colour systems?

Great apes and the right to health

This thesis focuses on enhancing predictions of central nervous system drug exposure using the LeiCNS-PK3.0, a physiologically based pharmacokinetic model.

The main aim of Eva's research is to create a frame of reference in which these animals as symbols must be understood, be they depicted on pottery, as amulets, as floor plans or in any other way. This frame of reference can then be used to interpret the various animal images encountered by Caribbean…

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

From the virtuosic songs of a nightingale to the various alarm calls of a great tit, bird sounds are incredibly diverse. They are among the most complex sounds in the animal kingdom and, according to Darwin, resemble language more closely than the vocalisations of other animal groups. But what do we…

Tuberculosis bacteria and other intracellular pathogens use cells of our immune system as Trojan horses to spread into tissues. Annemarie Meijer, professor of immunobiology, explains how research into innate defence mechanisms using zebrafish inspires novel strategies for infectious disease treatmen…

kiem grant: Investigating the anti-inflammatory potential of the PRG4 protein in preventing and alleviating rheumatoid arthritis

Vaccines are an extraordinary category of biopharmaceuticals. They are usually prophylactic and come in many types, from whole bacteria to peptides and nucleic acids. They are very cost effective and almost every human on the planet is vaccinated. The latter mandates that vaccines have to be extremely…

In her book Between Smiles and Grimaces, Mariska Kret shows us what differences there are between humans and animals, and more importantly, what similarities.

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

A research goal for ABS is to develop miniaturized platforms for research in (stem)cell, in-vitro systems and application in clinical and preventive research. Combined with the high throughput, this development will make it possible to study the dynamics of pathogenesis in human and cellular models…

The research aims to understand how did Cuban and Dominican landscape encapsulate historical conceptual transformations about human –nature spiritual interaction after the Spanish conquest? More specifically, what are the present day cultural associations with Cuban and Dominican natural landscape?…

Uncover novel antimicrobials with prospective health benefits for sea turtles.

The role of domestic and wild resource exploitation in Bronze Age subsistence

The master's specialisation Molecular, Cellular and Organismal Biology at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

Every day, the intestines face an enormous challenge. They must absorb nutrients, medicines, and other substances we consume, while keeping harmful compounds out.
