Magnets for electric cars and wind turbines contain only a small amount of the rare earth metal dysprosium. Yet, this metal is responsible for a large share of the environmental impact and costs, according to research by environmental scientists Stellina Samuel, Robert Istrate and René Kleijn.

Astronomers have measured the mass of a dormant, supermassive black hole in the early universe for the first time. Thanks to a combination of the James Webb Space Telescope and a natural cosmic magnifying glass, researchers were able to weigh the black hole directly based on its gravity.

For the second time this academic year, Nobel Prize winner Paul Krugman visited The Hague. Addressing a packed lecture theatre in our new Spui building, he spoke to students, staff and professionals about the tension between economic advice and political decision-making.

Reaching the end of the academic year, we look back fondly on the symposia, conferences and events that our faculty hosted in the previous months.

LUC researcher Bernardo Almeida explores in his VENI research, sponsored by NWO, what happens on land rights of vulnerable groups when climate responses meet fragile governance s…

Always losing your way, even in places you’ve been visiting for years? You may have Developmental Topographical Disorientation (DTD). Psychologists from Leiden are investigating this relatively little-known condition at the Lowlands festival. ‘The ideal place to study getting lost.’

Researchers at the Faculty of Science work at the frontiers of knowledge every day, tackling today’s major societal challenges. Their work is recognised through grants, prizes and other awards. We highlight some of these achievements below.

The European Space Agency (ESA) has officially adopted ARRAKIHS as a scientific mission, confirming the target launch date of 2030. Matthieu Schaller is part of the Science Team: ‘I look forward to learning more about the dark part of our cosmos.’

Astronomers have discovered an enormous supply of cold molecular gas in a galaxy shortly after the Big Bang. The finding offers a rare glimpse of the raw material from which the first large galaxies were built. Measurements suggest that around 95 per cent of the normal matter in the galaxy studied,…

From toy cats that purr to robot dogs that bark: what do such technologies mean for older people, healthcare providers and family members? A Dutch Research Council (NWO) Veni grant is enabling anthropologist Tanja Ahlin to investigate how animal-shaped robots can contribute to care for older people…

Drones zijn in korte tijd onderdeel geworden van het dagelijks leven. Ze worden gebruikt door hobbyisten, bedrijven, politie en defensie. Tegelijkertijd groeit de zorg dat dezelfde technologie ook kan worden ingezet door kwaadwillenden. Onderzoeker en promovendus Stijn Willem van 't Land zocht dit u…
