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…

How do stars and galaxies form? What is dark matter? To answer these and other questions, we need increasingly large telescopes. And to build these, we need international partnerships. A series on the impact of collaboration.

The number of insect species is plummeting, which is why the University is creating a more biodiverse environment around its buildings. Annetje Ottow, President of the Executive Board, planted the first bee-friendly plants in the front garden of Oude UB on 20 September.

Rich countries are getting richer because of environmentally polluting (construction) investments from the past, largely at the expense of poor countries. This was shown by long-term economic and environmental data. 'The gap between poor and rich countries is widening.' Scientists from the Leiden Institute…

What does it mean for a citizen to be ‘literate’ in astronomy? Astronomers who participate in outreach to the general public experience various degrees of astronomical knowledge among people. But so far, there had not been a systematic evaluation and definition of what astronomical literacy actually…

PhD student Willem Noteborn has investigated supramolecular structures. These can be useful for the loading of medicines and signalling molecules regarding, for example, cellular differentiation. In his thesis, he describes the functioning of these structures.

The race to build the first quantum computer is still ongoing, but Morten Bakker has made big step forward in that process with qubits. A qubit is a unit of quantum information that can be produced in large numbers on chips. Qubits capable of exchanging photons (light particles) could be used in the…

Cultural anthropology students study how architecture influences student behavior, safety, and community at MBORijnland through fieldwork research.

Recently, the so-called refugee crisis has been framed as a threat for well-developed welfare states in Europe by the president of the Eurogroup, Jeroen Dijsselbloem. According to him, external borders have to be guarded, because otherwise ‘loads of people will come to demand support and they blow up…

Amino acids are the building blocks for life on earth. They may originate in space and reach the Earth via comets and meteorites. Daniël Paardekooper examined part of this hypothesis. PhD defence on 5 July.

To check whether the classroom scanners are secure, a ‘pen test’ was performed in the Lipsius building on Monday 28 March. This involved switching on the person counters for a day so that ethical hackers could try to gain access to the system.

Many children experience trauma and if they are unable to deal with it properly, it can have a huge personal and societal effect. Building resilience in vulnerable children and young people should therefore have the highest priority. This is the message of Anne-Laura van Harmelen, Professor of Brain,…

Only one out of six professors in the Netherlands is female. At the Institute of Biology Leiden (IBL) female professors are in minority as well. However, we are proud to have three female professors at the IBL. Amongst others, their photo portraits are currently on display in the Senat Room of the academy…

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…

Political scientist Matthew Longo (Leiden University) takes a detailed look at the evolution of border security in the United States after 9/11.
