From science to startup: How do you approach it? Why should you take your research to the market in the first place? And what obstacles will you face? ‘It takes time to find a company that matches your motives.’

Smiling faces, sweltering heat and a record-breaking donation – that was the Leiden Science Run 2025. On Saturday 21 June, the Leiden Bio Science Park turned bright orange as enthusiastic runners completed 4.5 kilometres to support research for vulnerable children.

You win the Leiden Teaching Prize and suddenly all eyes are on you. Three past recipients reflect on how this student-awarded prize has changed how they work and improved their teaching – and how they chose to spend the money.

Fossil teeth can preserve remarkable information, much like a biological identity card with data about the lives of individuals tens of thousands of years ago. By analyzing teeth, a new study published in Science Advances reconstructed the life history of four straight-tusked elephants (Palaeoloxodon…

Over hundreds of thousands of years, our region witnessed the comings and goings of various types of hominin. This depended on the temperature as ice ages alternated with warmer periods.

Science thrives on freedom, safety, and stability. But what if these prerequisites are lacking? What if colleagues beyond our borders are threatened, persecuted or forced to flee?

Five consortia within the Perspectief programme that include Leiden researchers have received funding to start their research projects. These projects focus on (further) developing technological innovations, with societal and economic impact at their core.
