Do you want to design your own scientific project? And be involved in its fundraising and execution? iGEM Leiden offers you a place to challenge yourself in every way imaginable.

An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star. The researches, including Melissa McClure, used the James Webb Space Telescope and publish their findings…

Dutch politics is becoming increasingly polarised, and forming stable governments seems more difficult than ever. In the heat of the election race, a psychologist and a historian offer cool-headed advice.

Is our musicality unique? That’s what the Bird Singalong project aims to find out. And for that, they need the help of feathered friends from all around the world. ‘By researching how parrots learn songs, we also learn more about the origin of our own musicality.’ Do you have a parrot that can sing…

The many thousands of small celestial bodies beyond Neptune’s orbit may have ended up there due to a star that passed close to the solar system billions of years ago. This is shown by Leiden simulation expert Simon Portegies Zwart, along with his German and Dutch colleagues. ‘We are answering several…

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor…

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 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…

Astronomers have found complex organic ice outside the Milky Way for the first time. The discovery shows that the building blocks of life could arise early in the universe - and under a variety of conditions, said Leiden astronomer Will Rocha.

Using the James Webb Space Telescope, an international team of researchers, including Leiden Professor of Molecular Astrophysics Ewine van Dishoeck, has discovered a palette of hydrocarbons in a planet-forming disc around a young, low-mass star. The results confirm that discs around very lightweight…

With the new academic year, the Honours Academy welcomes a new assessor: Maarten Kolpa. What does an assessor do? And what can he do for honours students? Maarten talks about it in an interview. "I find it important that the student perspective comes first."

Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…

Computer scientist Matthijs van Leeuwen is one of four science faculty members who obtained the Senior Qualification in Education in 2021. What was that like and what drives him? ‘In my own education I would have liked to see more attention paid to the responsibility that machine learning and data mining…

Egyptologist Marleen De Meyer has been appointed the new Director of the Netherlands-Flemish Institute in Cairo (NVIC). Dr De Meyer has worked for the institute, which promotes Egyptian, Dutch and Flemish collaboration in the field of education and research, since 2016.

Citizens still see great value in science communication and want to be increasingly involved in science. This is evident from research by the National Expertise Centre for Science & Society (NEWS) and researchers from the Science Communication and Society department at Leiden University.

Speaking for the Executive Board, Timo Kos reflects on the university’s security policy and what lies ahead. ‘We want to keep our buildings open, but we also need to be able to guarantee the safety of everyone there. It’s a real balancing act.’

Marco van Eijk is the new Educational Director of the Bachelor's Life Science and Technology (LST). Since 1 September he has been responsible for ensuring the quality of the programme. ‘LST is a unique programme and everyone has to keep working hard for that. That is my main task.’

With a healthy dose of logic and creativity, mathematics student Lance Bakker shows how computers can prove complex mathematics. His method proves intricate formulas without calculating every intermediate step. It earned him a nomination for the Leiden Science Young Talent Award 2025.

From 1 October onwards, Dennis Claessen and Marcel Schaaf will be the new directors of education of Biology. They will replace Han de Winde. Schaaf will be responsible for the bachelor, while Claessen will mainly focus on the master tracks of Biology. We gave students and the education office the change…

The experiential expertise of people with a disability needs to be integrated in diversity & inclusion policy. This message was the common thread at the annual Diversity & Inclusion symposium. Students and staff members engaged in conversation about how the university can become more accessible.

Luckily we’ve been able to meet up on campus again for a few months now after two years of mainly online teaching. Alongside the inconvenience, enforced digitalisation has brought us valuable innovations and smart tools. The question is: what’s going well and what could we do differently? I’d love to…

Alexander van Oudenhoven is the brand-new education director of the master's in Governance of Sustainability. The study has already entered its fourth year and Van Oudenhoven is very enthused. What makes this a special programme and what are his plans?

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.

Students at Leiden University believe that their degree programmes should focus more on sustainability. These are the findings of a survey of more than 550 students by Leiden University Green Office.

In 2022, Leiden will be the European City of Science. The preparations are in full swing, so we would like to give you a look behind the scenes. This time we talk to Ewine van Dishoeck. She is the driving force behind the annual programme at the Faculty of Science. As far as she is concerned, there…

Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

PhD candidate Sibel Bahtiri is one of the new Faces of Science. In videos and blogs, she will show what life is like as a young researcher.
