Tanja Masson-Zwaan on 'Spraakmakers' about mining the moon
Commercial parties offering space travel, space waste, claiming the moon, potentially exploiting resources ... It’s going to get busy in space in the coming years. But there are no clear agreements about this. Tanja Masson-Zwaan, Assistant Professor of Space Law, talked about the topic in Spraakmakers…

One-way traffic for motion in new material
Scientists have developed a material that breaks one of the fundamental principles governing many physical systems. Ordinary materials transmit external forces equally, no matter where the pressure comes from. The newly developed material breaks this rule and could potentially be of interest in soft-robotics…

Materials from the past contain lessons for today
Studying ancient materials and the way they were made can give us groundbreaking insights into the past. Not only that, the interplay between people and materials is highly relevant for society today, says Ann Brysbaert, Professor of Ancient Technologies, Crafts and Materials, at the Faculty of Archaeology.…

Alternative story forms: a fresh approach to historical case material
Students taking the new bachelor’s course ‘Social Movements and Political Violence’ are about to do something new. In addition to studying textbooks and academic articles, they will actively work with multimedia materials and engage in online storytelling. Course instructor Corinna Jentzsch (Leiden…

Ultra-thin material absorbs all the light
It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

New material challenges 250 year old building principles
Researchers at FOM-institute AMOLF and the Leiden Institute of Physics (LION) have developed a rubber rod with strange bending behaviours. Beyond a certain point, it bends more under decreasing pressure. This behaviour doesn’t fit our expectations and does not conform to secular laws that predict the…

Newton-telescope finds missing intergalactic material
Astronomers from, among others, SRON and Leiden Observatory have discovered long-sought intergalactic gas with ESA’s space telescope XMM-Newton. This gas is one of the pieces of the puzzle to map the total amount of ‘normal’ matter in the universe. The research will be published in Nature on 21 June…

Indigenous Peoples preserved
Indigenous Peoples possess rich worldviews and unique knowledge that form part of our global heritage. Oppressing these peoples and violating their natural environment is leading to the destruction of this knowledge. Leiden researchers aim to counter this through collaborating with Indigenous Peoples…

On the coexistence of Landau levels and superconductivity
In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

Why the WTO ban on China’s export duties should be ‘greened’
China is prohibited from using export duties to address any environmental problems. This is unfortunate, according to PhD candidate Fengan Jiang (Richard), as export duties could be useful in tackling global carbon leakage. PhD defence on 19 February 2020.

Building materials drive carbon emissions, and they’re set to grow
A new study from Leiden researchers shows that the carbon emissions of building materials are set to grow if we do not act rapidly. Even with known interventions implemented in concert, these emissions are much larger than the remaining 1.5 degree budget for building materials at today’s share, the…
