Space is becoming increasingly busier due to the launching of satellites and tourists. But no binding international agreements have been made since 1979. This is problematic, warns space lawyer Tanja Masson-Zwaan. ‘Everyone’s putting their own interests first.’

On 3 June, Annetje Ottow (chair) and Hester Bijl (rector magnificus) met the Humanities faculty. Although a physical introduction was preferred, this visit also had to be done digitally.

For the eleventh time in a row, Leiden University’s unique liberal arts and sciences programme has been awarded the ‘Top Rated Programme’ quality seal by Keuzegids universiteiten 2024.

What do you do if you have a book from the sixteenth or seventeenth century, but you suspect that the binding contains a fragment of a medieval manuscript? University lecturer Thijs Porck has received an NWO grant to experiment with a camera attached to a tube. 'The project boils down to keyhole surgeries…

Sometimes an idea seems so logical and elegant at first glance, that you later wonder why no one thought of it before. Two researchers from LACDR have teamed up to develop a completely synthetic alternative to antibodies—one that mimics their size, shape and function, but which is cheaper, more stable,…

Since September, Jelle Oonk has been the chair of the Science Faculty Council. Jelle is a third-year student, combining Physics and Astronomy studies with this responsible role. Time to get to know him better. Five questions for the new chair.

Cramming from a book, making notes or learning summaries. In the past these were about the only ways to memorise your course material. But that has long since changed. Multimedia is the code word. But is it effective?

When you think of a library, you probably picture books – or students quietly studying. But for subject librarian Rutger de Jong, most of the work happens online. ‘We never throw anything away. Everything produced here in the name of science should remain findable.’

A flu virus could cause a pandemic. And then we would be poorly armed because flu viruses are starting to become resistant to flu medications like Tamiflu. Chemist Merijn Vriends successfully worked on an improved version of such medications. He will be awarded his doctorate on September 12th.

He had been emeritus for 13 years when he suddenly received an email from Poland. Professor of Inorganic Chemistry Jan Reedijk was awarded an honorary doctorate from Nicolaus Copernicus University in Toruń. During the celebration of the 550th anniversary of the birth of patron Nicolaus Copernicus,…

Young researchers met this month for the fifth Science Communication Summer School. ‘This is the first time some participants get to meet other researchers who also enjoy science communication. It’s great to see’, says Julia Cramer, one of the coordinators.

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.

What do you do when you get the chance to meet Nobel Prize winners in your field? You say ‘yes’, of course! Two young chemists from Leiden had the opportunity to attend the Nobel Laureate Meeting in Lindau, Germany. They share what the experience was like.

Violette Defourt came to Leiden for her master’s just before Covid hit. Four years later, she is leading her own biotech company, which aims to radically speed up diagnostics.

White clouds of ice-cold gas flowing across the floor. Magical, but be careful not to freeze your fingers off. We are of course talking about liquid nitrogen and helium. You may have seen the spectacular Freezing Physics science show by the student organisation Rino. But did you know that this commodity…

How safe are the nanoparticles in transparent sunscreen, anti-odour socks and bacteria-resistant plasters? Although microbes are present on all organisms, the tools that estimate the safety of nanomaterials still hardly take them into account. Bregje Brinkmann explored the role of these microbes during…

Imagine we could do what green plants can do: photosynthesis. Then we could satisfy our enormous energy needs with deep-green hydrogen and climate-neutral biodiesel. Scientists have been working on this for decades. Chemist Chengyu Liu will receive his doctorate on 8 June for yet another step that brings…

An international team of astronomers including Leiden professor Ewine van Dishoeck has observed the benzene molecule (C6H6) in a planet-forming disk around a young star for the first time. The observations tell us more about the forming of planets in this disc, like our own Earth. The scientists publish…

Sense Jan van der Molen is vanaf 1 maart de nieuwe wetenschappelijk directeur van het Leiden Instituut voor Onderzoek in de Natuurkunde.

Due to technological and societal developments, we are being flooded with more information than our brains can process. How does this affect our decision-making, both as individuals and as a society? And can we learn to make better choices? This is what Lotte van Dillen will explore with her profess…

For decades, the trade in pocketbooks prescribing how to be a good Muslim flourished in East Africa, but in recent years the number of books in circulation has been declining. University lecturer Annachiara Raia is the recipient of an Impact Explorer grant to revive this tradition, in cooperation with…

How do you turn your thesis into an academic article? That's a question Floortje Fontein, who conducted research into inclusive leadership, can answer. She looked at how public managers manage a diverse team. She got a 9 for her thesis and is currently working on several articles based on the results…

How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

When we think about ancient Egypt, the first things that come to mind are usually mummies and sarcophagi. According to researcher and Rijksmuseum van Oudheden curator Lara Weiss, that impression is unjustified. She made an audio tour for the Rijksmuseum van Oudheden that focuses on living Egyptians…
