Leiden molecular cell biologists in the research group of Annemarie Meijer have discovered novel early macrophage-specific genes in zebrafish, including a signal transducer pivotal for the migration of macrophages in the innate immune response to bacterial infection. Their findings were published on…

This project aims at providing a broad perspective of the state of Science Technology and Innovation (STI) in Africa with a focus on global funding flows, in order to inform research funders in the continent, in particular those participating in the Science Granting Councils Initiative (SGCI). The project…

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

Leiden chemists, together with colleagues at the University of York (UK) and Technion (Israel) have discovered a small, sugar-like molecule that maintains the integrity of tissue around a tumour during cancer. This molecule prevents tumour cells from spreading from the primary cancer site to colonise…

Leiden physicists are helping Wageningen plant researchers to study unpredictable plant embryos. For this, they are using a novel two-photon fluorescence microscope, aided by a 30 thousand euro ZonMW grant.

An international group of scientists has discovered that certain cells of our immune system – the so-called T cells – communicate with each other and work together as a team. To fight an infection they stimulate each other’s growth, but at the same time, they inhibit each other when there is a surplus…

Paul Brakefield, Professor of Evolutionary Biology at the Institute of Biology in Leiden (IBL) has been awarded an ERC Advanced Grant for his research. He will receive 2.5 million euro to develop his research programme over a period of five years.

This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

On Thursday the 24th of November, Tseard Hoekstra and Jeroen Ververs (members of the delegation Holland Rijnland), Geert de Snoo (Dean Faculty of Science), Martina Vijver (CML), Herman Spaink (Scientific Director IBL) and Klaas Vrieling (IBL) explored possibilities for collaborations between companies…

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

With the necessary measures, researchers restart their work in various laboratories. The Leiden Cell Observatory is one of the places where scientists resume their lab work.

This edited volume provides a synthesis on the question of business attitudes towards and its influence over the development of the modern welfare state. It gathers leading scholars in the field to offer both in-depth historical country case studies and comparative chapters that discuss contemporary…

When the immune system attacks cancer, the tumour modifies itself to escape the immune reaction. Researchers at LUMC published on this subject in Nature on 28 June.

It is the dream of Professor Susana Chuva de Sousa Lopes to grow fertile egg cells in the lab. But she says there is a long way to go in her discipline until that is possible. This is the message of her inaugural lecture on 29 June 2020, the first digital inaugural lecture at Leiden University.

An external visitation committee gave the Institute of Biology Leiden (IBL) an outstanding assessment. In terms of research quality and relevance to society, the IBL gets the highest score: excellent. The increase with five new female professors also receives praise from the committee.

On 22 June, Najib Amin defended the thesis 'State-building, lawmaking, and criminal justice in Afghanistan: a case study of the prison system’s legal mandate, and the rehabilitation programmes in Pul-e-charkhi prison'. The doctoral research was supervised by Jan Michiel Otto and Pauline Schuyt.

Leiden biophysicist Stefan Semrau was granted an NWO Vidi earlier this month. He will use the grant to study the role of electricity in embryonic development and tissue regeneration.

Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

The research addresses the question of “what is the impact of geopolitical changes to the pivot states in the Middle East? With special focus on Turkey, Iran and Saudi Arabia.”

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

This book offers a comprehensive analysis of China's global resurgence and its effects on U.S. dominance.

Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…

Researchers from Leiden University Medical Center (LUMC) and Netherlands Cancer Institute (NKI) have discovered how specialised immune cells can detect and remove cancers that are ‘invisible’ to the conventional defence mechanisms of the immune system. Their work has been published in Nature. The findings…

Joost Beltman (LACDR, Leiden University) has provided novel insights in the way T cells migrate towards virus-infected cells. This was accomplished by a combination of experimental research in the group of Ton Schumacher (Dutch Cancer Institute, NKI) and computer simulations in collaboration with Rob…

Ramesh Ganohariti will examine legal identity in three post-Soviet aspirant states and outline four common scenarios in this article.

Does foreign aid promote human rights?

American pharmaceutical company Bristol Myers Squibb will be building a new (CAR-T) cell therapy facility in the Oegstgeest part of the Leiden Bio Science Park. The company will manufacture and develop CAR T-cell therapy for patients with blood cancer (leukaemia), for example.

Mechanics play a larger role in blood vessel formation, and other developmental biology, than previously thought. Cells appear to respond to mechanical signals, such as pressure. Through the extracellular matrix, a network of fibrous proteins, cells can supposedly exchange those mechanical signals over…

In breast cancer, metastasis rather than the primary tumour is the cause of death. A lack of oxygen in the tumour cells promotes this metastasis, accompanied by a reprogramming of the cell's metabolism. PhD candidate Qiuyu Liu investigated these alterations to get more knowledge about the actionable…

Gilles van Wezel has been appointed the new Scientific Director of the Institute of Biology Leiden starting September 1st, 2018. Van Wezel succeeds Herman Spaink, who has been the Scientific Director since September 2014.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

On 28 February 2019, Kabir Duggal defended his thesis 'Principles of Evidence in Investor-State Arbitration, Burden, Standards, Presumptions & Inferences'. The doctoral research was supervised by Prof. dr. E. De Brabandere.

In this article, the authors explore why there is substantial cross-national variation in the level of regulatory clarity surrounding cryptocurrencies

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.
