The Service Centre International Staff supports and advises all international staff at Leiden University. Not just about things like immigration, accommodation, taxes, insurance and dual career, but also about the social side of things like feeling welcome and at home at Leiden University. SCIS’s recent…

Several Dutch universities have said they do not want foreign student numbers to grow any more in some of their degree programmes. They are reaching maximum capacity. We are also alert to this in Leiden, but I see many positive aspects to the intake of international students.

Nikie Veld is an education coordinator at Biology. Her job now mainly revolves around getting students back to the Faculty. ‘In the corona era, we were constantly rearranging the timetables.’

Back to university to attend lectures with master's students: that's what professionals did at the Leiden Leadership Programme. Conclusion of the experiment? Learning about leadership leaves one wanting more. 'Great that this is possible.'

Understanding the behaviour of tiny droplets in our cells could aid the search for new treatments. A team of Leiden researchers has developed a groundbreaking method to study how these droplets transition from liquid to solid. This change plays a role in various diseases, including neurodegenerative…

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 exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.

Micro- and nanoplastics cause stress to crops such as lettuce and carrots, PhD candidate Laura Julia Zantis found. This can lead to reduced growth and a lower nutritional value. Biodegradable plastics have this effect too, likely because of chemicals they release during degradation.

Scientists have discovered that starlings and parrots can imitate the complex sounds of Star Wars droid R2-D2 remarkably well. Their study reveals how the structure of a bird’s vocal organ determines its vocal abilities – and how citizen science helps uncover it.

The life cycle of comets near the star Beta Pictoris is similar to that of comets in our own solar system. This is the conclusion of a team of astronomers from the Netherlands, France and Brazil. It seems that, just like in our own solar system, there are fewer comets as the star gets older. The researchers,…
