The transition from single cells to multicellular organisms was a key step in evolution. Researchers from Leiden and Amsterdam developed a mathematical model that explains how this transition may have come about. They suspect cooperating cells may correct each other’s mistakes. Publication in eLife…

Researchers and clinicians at Leiden University Medical Centre (LUMC) are about to begin a milestone clinical study.

How did people move and form communities when human societies first shifted from hunting and gathering to farming? A new study of the Neolithic period in southwest Asia, the birthplace of agriculture, offers fresh insights.

Professor of Law and Society, Maartje van der Woude, had an interview in ‘De Groene Amsterdammer’ of 4 September 2018 about her research into mobile border control.

Leiden and Austrian researchers have succeeded in further uncovering how a plant cell passes on the growth hormone auxin in a directional manner to the next cell. Three proteins that cling together in a bunch appear to be essential for this important transport process. ‘This discovery solves a crucial…

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

Bacteria temporarily live without their cell wall if dangerous viruses are near. A remarkable feature, as the cell wall is a sturdy barrier against threats. Still, the discovery has a logical explanation ánd might be of a consequence for fighting pathogenic bacteria, according to Véronique Ongenae,…

Cells in our bodies are often threatened by errors in our own proteins. The FLOW consortium, comprising scientists from various institutions including Leiden, is poised to meticulously map out for the first time how cells control proteins, correcting or removing faulty ones. This endeavour holds promise…

Researchers from the Leiden Institute of Chemistry show proof of principle that live-cell structural changes and metabolic processes can be followed in real time with NMR spectroscopy. They performed their study on photosynthetic green algae that are metabolically flexible and can sustain energy generation…

A COVID-19 vaccine that specifically instructs the immune system to produce T-cells rather than antibodies is shown to provide good protection in a mouse model, Leiden University Medical Center (LUMC) researchers report in Nature Communications. According to them, the alternative vaccine may offer a…

Dennis Claessen has been appointed professor of Molecular Microbiology at the Institute of Biology Leiden. With his teaching and research on the cell wall, the professor wants to establish applications in the industry and the medical sector.

How can we prevent drug-induced liver and kidney damage? PhD candidates Marije Niemeijer and Lukas Wijaya investigated what happens in the cells during the onset of this damage: a stress response. Both focused on a different subtopic and made some interesting discoveries.

What’s really happening in the space between the cells in your body? With the Collagen Canvas project, students from Leiden University invite you to explore this question by blending science with art. This interactive artwork immerses you in the dynamics of the extracellular matrix—the invisible structure…

A more efficient solar panel sounds great. But what if these new panels consume more toxic materials, or their production consumes a lot of energy? Leiden environmental scientists, together with colleagues from the Fraunhofer ISE, address this multifaceted question in a new publication in the prestigious…

Peter Slort is the highly driven portfolio holder for Diversity with the Dutch National Police. Since November 2016 he has been spreading the importance of diversity throughout the police organisation.

For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment. Biochemist Fatema Zahra Rashid managed to do this using a technique she fine-tuned. Her research into changes in 3-dimensional chromosome structure offers clues for ways…

Roxanne Kieltyka was interviewed for NRC and talks about squaramides, cell cultures and Goldilocks.

A team of students from Leiden won the iGEM international biology contest in 2020 with their Rapidemic mobile testing kit. The kit makes it easy to detect viruses. The team has now been nominated for the Most Innovative Student in the Netherlands prize. Cast your vote and help them develop their inv…

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

Destroying proteins from the Golgi apparatus of the cell in a controlled manner. That is the focus of chemist Marta Artola’s pioneering research. By developing a groundbreaking technology to target specific proteins in the Golgi, Artola aims to unlock new ways for drug development. For this ambitious…

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden PhD candidate Samuel Schwab has found that the histones in these organisms are much more diverse than previously thought. Schwab and his colleagues describe…

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

At high doses, drug candidate BIA 10-2474 binds not only to the protein that it targets, but to other proteins as well. It thus deactivates proteins that are involved in the metabolism of nerve cells. This is what an international group of researchers from Leiden University and Erasmus MC, among others,…

At the division of BioTherapeutics, Amanda Foks, Bram Slütter and Ilze Bot have obtained a €4 million research grant from the HORIZON 2022 EIC Pathfinder Challenge “Cardiogenomics”, entitled “B-specific: B-cell related gene and protein markers with prognostic and therapeutic value for CVD”.

How did persistent social inequalities first emerge? What cultural trajectories and institutions made this key development possible? How can archaeological inform us about the formation of class societies?

When you think of physics, do you think only of complicated formulas? You’re not the only one. Therefore, every year, the Leiden Insitute of Physics organises the LION Image Award to show another side of physics: beautiful images about intriguing science. The winner of the 2022 photo competition captured…

In this project we think about the relationship between territory and contagion. Tracing the historical, political, and conceptual linkages between territorial bordering and migration on the one hand and disease related phenomena like contagion, immunity, and inoculation on the other, we ask how the…

Seasonal influenza vaccines provide protection against matching influenza A virus (IAV) strains mainly through the induction of neutralizing serum IgG antibodies. However, these antibodies fail to confer a protective effect against mismatched IAV. This lack of efficacy against heterologous influenza…
