Hans Slabbekoorn researches animal sounds and the effect of the noise we humans make on these animals. He is also committed to making his discipline more diverse.

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.

The more data from cancer research we pool, the better we can search for new treatments. But how can we keep patient data safe when sharing it? Leiden researchers will tackle this challenge in a major European project.

Physicist Milan Allan will build an instrument that will bring superconductivity research further. He has been awarded an ERC Consolidator Grant of 2 million euros over the next five years. With his PairNoise programme he aims to detect paired electrons as they occur just above the temperature at which…

It was already the most cited publication ever written at our faculty, but now a new milestone has been reached. Last month, a paper by emeritus professor Jan Reedijk and his co-authors surpassed 10,000 citations — and the count keeps rising.

Professor of Fungal Genetics and Biotechnology Arthur Ram explains how fungi can help us be more sustainable.

Last week (25-29 October) was Healthy University Week 2021 ‘Time to Recharge’. A week devoted to vitality, with a programme packed with activities guaranteed to give you energy. Over 1,000 staff from Leiden University and the LUMC signed up for the daily energisers, relaxed during a yoga session and…

‘AI can’t do half as much as people think,’ says computer scientist and psychologist Roy de Kleijn. He tries to teach robots seemingly easy things, and keeps on discovering how smart human intelligence really is. Three things that computers are no way near doing.

Complex research with a generous sprinkling of jargon: PhD defences can be difficult for non-experts to follow. In the compulsory new lay talk, PhD candidates begin by explaining their dissertation in words of one syllable. And it’s not just the PhD’s family and friends who appreciate this.

What is the mission of our Faculty? How do we view diversity and inclusion? And how do we think about the growth of our Faculty in the broadest sense of the word? These themes were the focus of the first brainstorming session for the new faculty strategy. Some 65 staff and students from all levels of…

In the space of seven weeks, the staff of the LUMC and Leiden University have left home more than 35,000 times for a short walk, or an Ommetje as it is known. Healthy University Leiden launched the Ommetje walking challenge to encourage its staff to adopt a healthy lifestyle. Thus far this has resulted…

Tracking mucus-eating bacteria, mapping the complexity of planetary nebulae and a signalling pathway in cancer. These three Leiden projects have been awarded Open Competition Science-M funding by the Dutch Research Council.

The fact that scientists are increasingly better able to access molecular cell and tissue data also brings with it a new challenge: how can scientists find the information they need for research among the vast amount of data available?

Do you recall all those drugs that were hastily proposed as potential treatments for COVID-19? In the event of a future pandemic, the goal is to offer an effective treatment more quickly and efficiently. To achieve this, a team led by Coen van Hasselt is developing a platform that can speed up the process…

A time-lapse of the universe in more detail than ever before: that’s the aim of the NSF–DOE Vera C. Rubin Observatory in Chile, which will unveil its first images of the night sky on 23 June. Researchers at Leiden Observatory have played a major role in making it all possible.

PhD candidate Daniël Gomon has developed statistical methods that could significantly improve research in fields like medicine and demography. ‘Mathematicians don’t like unrealistic assumptions,’ he says. Gomon will defend his PhD thesis on 19 June.

Jasper Knoester is the dean of the Faculty of Science. How is he doing? 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.

There are more molecules that could conceivably be candidate drugs than there are stars in the universe. How can we ever efficiently identify those molecules? Professor of AI and Medicinal Chemistry, Gerard van Westen: ‘I’m going to use artificial intelligence as the co-pilot to make an automated search.’…

Researchers at LIACS have found a vulnerability in open-source code that’s been used around the world for over 15 years. They’ve also developed an AI-based tool to fix the problem automatically. ‘You really can’t afford to lean back.’

This month, ten teachers received a Senior Qualification Education (SKO), including Marcellus Ubbink and Daan van der Es from our faculty. Why did they go through the process of getting qualified, and should all teachers have an SKO?

Interdisciplinary and transdisciplinary collaboration can be tricky. We don’t all speak the same ‘language’ or know how to find each other. At the Knowledge Orchard anniversary event on 28 November, academics made and strengthened connections.

Soft structures that can take on different shapes without any external drive. Leiden physicists Daniela Kraft and Julio Melio created them in their lab. They present their groundbreaking research on microscale metamaterials in Nature - a breakthrough that opens the door to smart, reconfigurable materials…

What do you do when a discovery in the lab shows real promise? Scientist Mirjam Huizenga founded a startup to develop a new treatment for nerve pain caused by chemotherapy. ‘The goal is to give patients a better option.’

One in two people will be diagnosed with cancer. World Cancer Day on 4 February raises awareness of the impact of this devastating disease. Leiden University is conducting various studies aimed at preventing and controlling cancer. Below are just a few examples.

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

They are only a few tens of micrometres long — far smaller than the width of a human hair – yet these robots can swim, sense, navigate and adapt in ways that look surprisingly life-like. And all this without having a brain.

Collaborating in drug discovery and health research was the goal of a visit to the Leiden Bio Science Park on 14 May by a Swedish delegation including His Majesty King Carl XVI Gustav of Sweden. The delegation visited Leiden University’s Faculty of Science.

No more lectures and exams for the Radio Astronomy course taught by Michiel Brentjens. The corona crisis is a moment of reflection that has changed his whole way of teaching. Instead of being in front of the class, he lets his students build a radio telescope with paint cans.

The opening of the new academic year highlighted students' and lecturers' personal motivators. Incoming students were encouraged to be bold, forge their own paths and grow by trial and error.

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.

Are magnetic fields older than the first light? And how did they influence the development of our universe right after the Big Bang? Cosmologists from Leiden, Groningen, and Utrecht are now collaborating to investigate this.

How can you persuade researchers who are used to conducting research within clearly defined disciplines to adopt an interdisciplinary approach? Newly appointed distinguished professor Arnold Tukker explained.

While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…

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.…

A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…
