Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

This book contextualises case studies across a wide variety of languages and cultures, crystallising key interrelationships between linguistic standardisation and prescriptivism, and between ideas and practices. It focuses on different traditions of standardisation and prescription throughout the world…

An international team of researchers, including Federico Calle-Vallejo of Leiden University’s Institute of Chemistry, have taken the atomic-scale design of catalysts to the next level. Their research contributes to the quest for a method to generate or store energy more efficiently. The report is published…

On Friday 12 November 2021, the Net Zero Space initiative was launched at the Paris Peace Forum. The International Institute of Air and Space Law (IIASL) of Leiden University is one of the first supporters to the initiative.

Xander Tielens, Professor of Physics and Chemistry of the Interstellar Space, has been awarded an ERC Advanced Grant to study polycyclic aromatic hydrocarbons (PAHs) in space. The combination of astronomical observations, computer models and lab research makes the research highly interdisciplinary.

Adverse drug reactions (ADRs) remain one of the major reasons for patient mortality and (early) drug withdrawal. Currently, different in vivo and in vitro models are used to assess the toxic potential of drugs in the pre-clinical phase. Unfortunately, the predictive value of this model does not fit…

Toxys, Leiden University and Leiden University Medical Center have agreed immediately to commercialise and also develop further the ToxProfiler technology invented at the two institutions. ToxProfiler allows for rapid toxicity hazard identification of novel and existing drugs, chemicals, and other substances.…

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

We are launching more and more satellites and space is filling up as a result. Currently around 100 million pieces of space debris are floating around Earth. So who’s going to clear it up?

What chemicals do plants have available, and what happens if they use them when faced with bacteria or fungi? That is what PhD candidate Luis Salomé Abarca is keen to learn. He studies plants’ survival and their use of chemical components in communication and defence. Salomé Abarca works at the Natural…

Thomas Bakkum en Tom van der Wel, two PhD candidates from the Leiden Institute of Chemistry, have both won poster prizes at the EMBL Chemical Biology Conference 2018 in Heidelberg.

The European Commission has selected a consortium of major European launcher and satellite manufacturers, operators and service providers, as well as policy and legal research centres and institutes to study and provide guidelines and recommendations on Space Traffic Management (STM). The IIASL of Leiden…

A group of chemists, that includes Sander van Kasteren and Hermen Overkleeft, has discovered that azides, a certain type of chemical compound, can determine whether or not T cells respond to or ignore a vaccine. Their discovery is set to be published in Angewandte Chemie.

The Dutch chemical industry is regularly in breach of safety legislation. These are the findings of longitudinal research by the Department of Criminology at Leiden University, in collaboration with the Department of Criminology at VU Amsterdam. Over the past ten years, the roughly 400 companies to…

Space travel has long since progressed from being just about rockets, travelling to the moon, and Russia and America. The Netherlands has its own Space Agency and one of its important tasks is collecting and making available increasingly advanced satellite data.

The alignment of the James Webb Space Telescope is complete. The space observatory is able to capture sharp, well-directed images with each of its four powerful scientific instruments on board. The MIRI instrument, on which Professor of Molecular Astrophysics Ewine van Dishoeck also worked, was the…

An artwork by Guy Livingston has been chosen to launch into space and be exhibited on the International Space Station.

One of the holy grails of drug research is to be able to assess the safety of chemicals and pharmaceuticals without using laboratory animals. Researchers from Leiden University, among others, now receive a grant from the National Science Agenda to pursue that goal.

The American Chemical Society’s Publication Division (ACS) and Dutch universities represented by the VSNU have reached agreement on including open access publication as part of the contract with publishers. From 2017, all new articles submitted by an author associated with a Dutch university or participating…

Tanja Masson-Zwaan and Dimitra Stefoudi of the International Institute of Air and Space Law (IIASL) in Leiden, along with two others, co-edited the book ‘Building Blocks for the Development of an International Framework for the Governance of Space Resource Activities. A Commentary’.

Space is of enormous strategic value. Having rules in space therefore is to everyone’s advantage.

If you could convert CO2 into building blocks for other molecules with the help of electricity, you could make the chemical industry considerably more sustainable. Leiden chemists have unravelled a fundamental part of this process and applied this knowledge in a real device, as they write in Nature…
