Nausea, neurologic pain and hair loss: some of the severe side effects of chemotherapy. Not necessary, biochemist Liyan Zhang showed. Together with Leiden biologists and others, she achieved great results with a drug that is only active in combination with light. Zhang will defend her PhD on 4 July.

Between 1993 and 2000 the Faculty of Archaeology had a formal cooperation with the Service Régional de l’Archéologie de la Guadeloupe, Direction Regional des Affaires Culturelles (DRAC) and the then director André Delpuech. During that period surveys and excavations were carried out at a number of s…

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

Microscopic swimmers such as bacteria do not always swim alone. There are advantages to exchanging information and cooperating. Stefania Ketzetzi and colleagues now show in Nature Communications that human-made microswimmers, too, can cooperate.

A new regional atlas, with information about the presence of pesticides in surface waters, has been developed by the Institute of Environmental Sciences (CML) in collaboration with Royal Haskoning DHV. The aim of the regional pesticide atlas is to support decision making at local and regional levels,…

The Dick Stufkens Prize 2021 for the best PhD thesis of the Holland Research School of Molecular Chemistry (HRSMC) has been awarded to Klaas van Leest for his thesis 'Open- Shell Cobalt Complexes with Redox-Active Ligands; Electronic Structure and Nitrene Transfer Reactivity'. Van Leest, who is now…

The channel through which two cell components exchange material appears to form at the edge of their contact surface, and not in the middle. This was discovered by the Leiden physical chemists Jelger Risselada and Edgar Blokhuis together with researchers from the University of Lausanne in Switzerland.…

Olivier Nieuwenhuyse, member of the Faculty of Archaeology, was successful in receiving a grant from the Bijvanck Foundation for a first campaign of work at Tell Begum, northern Iraq (Iraqi Kurdistan). A small international team directed by Olivier Nieuwenhuyse in a joint effort with the Directorate…

An international team of researchers including Leiden archaeologists has produced convincing evidence that 300,000 years ago pre-Neanderthal people had a high level of cognitive complexity. New insights into early human capabilities and behaviour.

When professor Frank Israel graduated at Leiden Observatory some forty years ago, little did he know that one of his theories would be making headlines in 2018 - in the form of a 3D animation on the Internet, no less.

On Tuesday 4 September, Martina Vijver delivered the scientific lecture during the academic opening of the Faculty of Science. Martina is professor in Ecotoxicology at CML and would like to have collaborations with colleagues from the Leiden Centre of Data Science. We had a brief interview with her.

Leiden and Jülich researchers discovered an elegant and simple approach to improve the sensitivity of graphene biosensors. These so-called ‘next generation graphene electronic biochemical sensor devices’ are able to detect very low amounts of HIV DNA thanks to their very low electronic noise.

The project has been done in the Quantum Matter Optics group under the supervision of Dr.ir. Sense Jan van der Molen. The title of the presentation is: ''A Technique for Studying Surface Profiles of Two-Dimensional Materials in LEEM.

A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…

Ten Leiden researchers have been awarded a Veni grant by the Dutch Research Council (NWO). The grant, of up to 280,000 euros, will enable them to elaborate their ideas over a period of three years.

In otherwise energetic desserts at the bottom of the sea, researchers have found oases where microbes can harvest energy. Remarkably, the microbes first have to be buried under starving conditions for 80,000 years. An international group of researchers, amongst them José Mogollón from the Insitute of…

Shell cooperates with theoretical physicists and chemists of Leiden University to research how quantum computer algorithms can help simulate complex molecules.

Leiden based chemistry student and chess grandmaster proposes molecular system for development of artificial leaf

With 8.9 million euros from the Danish National Research Foundation, Aarhus University and Leiden Observatory will establish the Center for Interstellar Catalysis. The centre is led by Aarhus professor Liv Hornekær and aims to find out how and when the building blocks of life formed in the Universe.…

Around the world, there is a growing movement to decolonise university curricula, with both students and educators seeking to disrupt existing epistemic hierarchies within higher education. This research project aims to unravel what decolonising means in general and what it means for the International…

Investigating Neolithic houses in Britain through microwear and residue analysis of stone tools

This long term project in Jordan is at the basis of many specialists’ studies and has several off-shoot projects. The project, with its many approaches, is also a framework for much teaching in Levantine Archaeology at Leiden University, especially concerning fieldwork methods, artefact studies, research…

Update : March 2020 Director: Professor Dr Harco Willems (KU Leuven), co-director Dr Marleen De Meyer (KU Leuven & NVIC)

Through metabolism, biochemical processes give rise to the complexity of life. Acquired and inborn errors in metabolism underlie many diseases occurring in man. The challenge for present day medical biochemistry is to find, and integrate, pieces of information at molecular, cell and organismal level…
