We will solicit blogs and we also invite authors to make their own pitch, addressing new themes and perspectives,…

Stefan Belderbos was the first visual artist to undertake PhD research in the arts at Leiden University. His doctoral defence is on 2 December. Not only will he defend his dissertation on the integration of performance art in liturgy, he will also exhibit the material results of his research in the…

Why is the sky blue? Why are most people right-handed? Why are spiderwebs so strong? These are just some of the questions arriving at Postbus 71, a Leiden2022 project where everyone can ask their questions. Friso de Hartog, the driving force behind Postbus 71, is busy answering as many questions as…

If three or more objects move around each other, history cannot be reversed. That is the conclusion of an international team of researchers based on computer simulations of three black holes orbiting each other. The researchers, led by the Dutch astronomer Tjarda Boekholt, publish their findings in…

South African poet Antjie Krog will be the writer in residence at Leiden University in autumn 2021. Krog is famous for her poetry collections and books, which are often inspired by the history of South Africa. In her role as writer in residence, she will give the annual Albert Verwey Lecture and a series…

Tiny selenium particles could have a therapeutic effect on ischemic brain strokes by promoting the recovery of brain damage. Pharmacologists, including Alireza Mashaghi from the Leiden Academic Centre for Drug Research discovered that selenium nanoparticles inhibit molecular mechanisms that are responsible…

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…

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…

For the first time researchers have succeeded in placing a layer of graphene on top of a stable fatty lipid monolayer. Surrounded by a protective shell of lipids, graphene could enter the body and function as a versatile sensor. The results are the first step towards such a shell, and have been published…

An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers,…

In October 2014, Leiden University established the ‘Leiden University Teachers’ Academy’. Helen Westgeest, who lectures in the BA and MA Art History and MA Media Studies, was put forward by the Faculty of Humanities for appointment in the so-called ‘LTA’.

The quality of vaccines is still often tested by using laboratory animals. That has to change, according to researchers from Leiden University and the vaccinological institute Intravacc. Together they went searching for a test method that makes animal testing unnecessary. The first promising results…

During the ‘Hour of Remembrance’ on 4 May, the University community remembers its students and staff who were killed in the Second World War. It also looks at freedom and oppression today. Three questions for Sara Polak, chair of the Hour of Remembrance committee.

Graphene floating on water does not repel water, as many researchers believe, but rather attracts it. This has been demonstrated by chemists Liubov Belyaeva and Pauline van Deursen and their supervisor Grégory F. Schneider. Publication in Advanced Materials.

Depression has traditionally been linked to increased inflammation. Innovative research by psychologist Eiko Fried refutes this popular assumption. He shows that specific depression symptoms such as sleeping problems explain this relationship. Publication in Psychological Medicine .

An international team of scientists including Leiden's Joe Callingham has discovered nineteen red dwarf stars that unexpectedly emit radio waves. The outbursts possibly originate from interaction with exoplanets. The results of the research appear in two scientific publications.

Density functional theory (DFT) with so-called semi-local exchange has been remarkable accurate for some dissociative chemisorption reactions on metals, but it has notoriously failed for others. A team of researchers from the University of California at Irvine and the Leiden Institute of Chemistry have…

Over the past months regular updates have been provided on the work of the Leiden Turnaround, Rescue & Insolvency team (TRI Leiden) in creating EU Cross-Border Insolvency Court-to-Court Cooperation Principles. During the last week of January this project was finalised, resulting in 26 EU Cross-Border…

Smallholder farms in tropical regions can double their crop production by 2030 compared to 2015, a study finds to which José Mogollón (Institute of Environmental Sciences) contributed. But to achieve this, the farmers must increase the input of phosphorus beyond what is currently foreseen. The study…

Tax collection has become highly complex and the system is creaking at the seams. Is there an easier way to collect taxes? This is the question raised by Rex Arendsen, Professor of Tax Law, in his inaugural lecture on 16 September.

How dangerous are micro- and nanoplastics? Do they affect the environment? What harm can they do to our bodies? Questions that we can now finally answer because of Fazel Abdolahpur Monikh. Together with his colleagues, he developed a method to detect and quantify nano-sized plastics. Their paper has…

A century ago, the French linguist Ferdinand de Saussure proposed that the relationship between the sound of a word and its meaning is fundamentally arbitrary. In a new study, a team of researchers from European and American research institutions, including Søren Wichmann from Leiden University Centre…

Two bacterial species team up inside the plant root system to rescue their host from fungal infection. This was discovered by a team of microbiologists and bioinformaticians from the Netherlands Institute of Ecology, Wageningen University, and the Institute of Biology Leiden. They also identified the…

Black Theatre, activist theatre by and for black South Africans, flourished under apartheid. However, according to Francis Rangoajane, the democratisation of South Africa has in no way diminished the importance of this art form. PhD defence 16 November.

Upcoming activities by PhDArts candidates Basma Hamdy, Danne Ojeda Hernandez and Joost Grootens

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

Bacteria and fungi on organic dairy farms are significantly different from those on conventional farms. That was discovered by postdoc researcher Sofia Gomes and her supervisors Nadia Soudzilovskaia and Peter van Bodegom in collaboration with the Louis Bolk Institute and Naturalis Biodiversity Centre.…

On Thursday 1 December 2016 at 13.45 hrs, Francisco Sepulveda Ramirez will defend his doctoral thesis ‘Residence in Tax Treaties' at the Academy Building of Leiden University. Supervisor is Professor F.A. Engelen.

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 new discovery proves that it matters which approach researchers take in analyzing large physical, social or biological systems that have a networked structure. Ever since the early 1900s, scientists have assumed each approach is equivalent. Now many results in statistical physics may no longer hold.…

Astronomers have discovered seven Earth-like planets around a dwarf star in our galaxy. Three of these planets are located in the habitable zone of this star, and may contain liquid water. ‘The next step is to study the atmospheres for signs of life. In Leiden we are experts in that area,‘ says planetary…

An international group of scientists, led by Leiden physicist Sense Jan van der Molen, has developed the first switchable molecular diode. You can turn this on and off through humidity. Vice versa, it is a humidity sensor at the nanoscale. Publication on 4 December in Nature Nanotechnology.
