Archaeologist Mike Field spent his summer holiday riding in the toughest horse race in the world, the Mongol Derby: 1,000km in ten days across the Mongolian steppe, following in the footsteps of the Genghis Khan’s messengers.

‘I already gave a talk about planets when I was five.’ With the theme of the 3 October celebrations being ‘Jong geleerd is oud gedaan’ (meaning something like, ‘You’re never too young to learn’), this year’s 3 October University was especially for children. Many parents came with their offspring to…

Space telescope Euclid is capable of unravelling the secrets of the universe. That is what the images published by ESA today show, according to astronomers working with the telescope's data. The images exceed all expectations. Scientists within the Euclid consortium, including astronomers Henk Hoekstra…

Do young people trust the law? That is what HC Law students are trying to find out.

No procession of professors, just a handful of people in the church and snowdrifts outside Leiden’s Pieterskerk: 8 February 2021 was no ordinary Dies Natalis. Carel Stolker transferred the rectorate to Hester Bijl, and Annetje Ottow became the new President of the Executive Board. With an honorary doctorate…

Rower Boudewijn Röell (31) already has one Olympic medal, but he's hoping to win another in Tokyo. 'At some point, though, you do have to stop.' Easier said than done in a time of corona.

The English-language interdisciplinary minor ‘AI and Society’ explores the role of artificial intelligence in our society. The interdisciplinary nature of the minor is proving beneficiary for students and lecturers alike. We sit in during a class.
