How do you fulfill a chairing position during a team meeting? How do you visualise a dataset for a presentation? How do you write the introduction to a scientific article? All Science students can find the answers to these and many more questions in the 100+ skill modules on the digital Science Skills…

‘The Oscars of the natural sciences’, is what they are called: the Breakthrough Prizes awarded annually in America by the Breakthrough Foundation. Part of this are the New Horizons prizes for early-stage researchers. Sebastiaan Haffert, researcher at the Observatory, is this year's winner.

To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

Patients with skin diseases such as eczema and psoriasis, sometimes spend a lifetime searching for the right medication. To help these patients faster and better, scientists across the country are joining forces. The Next Generation ImmunoDermatology (NGID) project, with LACDR professor Robert Rissmann…

Not everything that comes close to a black hole is swallowed by it. Black holes can also hurl material away, and that chance turns out to be considerably bigger than previously thought. Martijn Oei's accidental discovery and his subsequent research on it earned him a cum laude promotion on 12 Decemb…

With a self-converted red camper van, biologists and twin brothers Kevin and Marvin Groen go on a nature adventure in Eastern Europe. Together, they search for wild animals, beautiful nature and places to sport. From a long search for a bear in the Slovakian wilderness to the discovery that pelicans…

A new academic year means new courses. And that inevitably requires all sorts of new skills: academic writing, searching for sources, setting up a research project... The Science Skills Platform is packed with useful information. This way, you can easily help your students on their way.

Leiden PhD candidate Jo-Anne Verschoor discovered that nearly twenty percent of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. ‘Bacteria are just like people,’ says Verschoor. Her research was published in the journal Communications Biology,…

Data scientist Lindsey Burggraaff has won the second edition of the Krijn Rietveld Memorial Innovation Award. She receives the prize for her research into bioactive substances in food. ‘Burggraaff's work is situated at a unique intersection of data science, biochemistry and the fields of food and nutrition,’…

For her research into migration policy under different political regimes, Katharina Natter has been awarded the Gratama Science Prize for young, talented researchers.

On 22 November, Leiden scientist Jan Vonk received an ERC starting grant for his research on the building blocks of mathematics. This grant is not his first this year: in fact, this July Vonk also received a Vidi from NWO. Four questions to the scientist who got two grants this year.

Six researchers from Leiden University have received an ERC starting grant. This grant of on average 1.5m euros will enable the researchers to launch their own project, form their own research team and develop their best ideas.

On Monday, Minister of Education, Culture and Science Robbert Dijkgraaf attended the start of Orientation Week Leiden (OWL), the introduction week for international students at Leiden University. He welcomed the students and spoke with them about their ambitions and the problems they face.

On January 1st Jasper Knoester started as our new dean. How is he finding it? What kinds of things is he doing and what does his day look like? In each newsletter Jasper gives a peek into his life as dean.

More than 700 visitors got to know the Science Faculty during the Leiden Science Family Day. People of all ages could enjoy fascinating experiments, tours, interesting lectures, spectacular nitrogen shows and various workshops. It was an informative day with many (future) scientists, amazement and,…

Floske Spieksma will give her inaugural lecture as Professor of Mathematics of Operations Research on 1 September. A discussion about mathematical models, Venezuela, trembling knees, being the only woman, casinos, intuition and above all loving your job.

How are you doing in these strange and unprecedented times? This is the question we are asking our colleagues in this series of articles. This time we asked Erick van Zuylen, the University beadle. 'This year, I haven't been leading the PhD committee into and out of the chamber, wielding my beadle's…

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

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.

Researchers from the LUMC and the Universities of Granada and Almería have found a gut bacterium that is associated with stronger muscles in people and mice. Their findings, published in the journal Gut, hint at the potential for new probiotics to support muscle strength and healthy ageing.

To understand the universe as a whole, simulations on a cosmic scale are required. An international team of astrophysicists, led by Leiden University, is today making one of the largest cosmological datasets ever available for free. It comprises more than 2.5 petabytes of simulation data.

Yesterday, eight professors were simultaneously inaugurated as ‘Medical Delta professor’, at Leiden University, LUMC, TU Delft, Erasmus University and Erasmus MC. Ariane Briegel, researcher of the Institute of Biology Leiden of Leiden University, also received the double appointment.

Leiden University is part of a Dutch consortium that will receive 4.7 million euros from NWO to build a facility that makes controlled, thin layers of material. The facility can produce small and large films, something that is globally unique. And that is key to scaling up, for example, new catalysts…

Vice-chairman of the Executive Board Martijn Ridderbos will leave Leiden University at the end of this year.

The academic year has officially begun! Hundreds of colleagues and students came together on 6 September to see each other again after the quiet summer months. A truly festive gathering, with live music and an evening lecture by Ignas Snellen.

Last year, 15.8% of all employees of Leiden University experienced undesirable behaviour. This is one of the findings of the 2021 Personnel Monitor. ‘That number is far too high. We have to get rid of the taboo on raising this issue and addressing offenders,‘ says Martijn Ridderbos, in an open and…

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

An international team of astronomers led by Dutch scientist Martijn Oei has discovered the largest pair of jets from a black hole ever seen. The 'jumbojets' extend a combined length of 140 Milky Ways. The Leiden Observatory played a prominent role in this research. The publication will feature on the…

A stronger focus on personal talents and team science. ‘Stop searching for those elusive hen’s teeth: they’d only get in the way’, says Professor Laura Heitman about Academia in Motion. ‘It’s unrealistic to excel in everything.’

The highly successful deep-sea telescope KM3NeT can now expand both its size and scope. Using a new type of microphone for underwater use, the telescope will attempt to detect the sound produced by neutrinos as they travel through the sea. The data collected will also be of great interest to other research…
