You can now submit new projects…

A special type of mirror to reflect X-rays has more possible applications than space research. Targeted radiation therapy for cancer, for example. Next to his full-time job, physicist David Girou mapped out the possibilities. He will receive his PhD on 14 June.

Various thought-provoking questions have been appearing online and in print adverts. They are part of a national university funds campaign in which the Leiden University Fund (LUF) is also participating. We wanted to find out more, so we called LUF Director, Lilian Visscher.

Rather than one key and one strong lock, biology often uses tens or hundreds of weaker links to bind parts together, such as cells membranes. This allows for selectivity and also reversibility: the binding can also be undone. Researchers first caught this phenomenon using spheres or colloids, and published…

Researchers from the Netherlands Cancer Institute, the Leiden University Medical Center (LUMC) and Oncode have created a tracking system that can reveal how often cells have divided. This allowed them to find a yet undiscovered population of immune cells: young memory cells that behave like stem cells.…
