The discovery in 2001 of the importance of microRNAs turned the world of molecular biology upside down. The small particles of RNA also attracted the attention of university lecturer Erno Vreugdenhil. Vreugdenhil: ‘Within five to ten years the first microRNA-directed medicines will come onto the mar…

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.

Gold nanoparticles give us a better understanding of enzymes and other molecules. Biswajit Pradhan, PhD candidate at the Leiden Institute of Physics, uses gold nanorods to study individual molecules that would be challenging to detect otherwise. Resulting knowledge can be applied to many research fields,…

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…

He is occupied with the home stretch of his promotion. But in between, there is another challenge: Michael Meijer is going through to the finals of ‘The Smartest Chemist of the Netherlands’. On Tuesday 9 October, he and five others fight for this title during the Evening of Chemistry. ‘I was dragged…

How ethical is research involving humans and robots? And can research on artificial intelligence cause problems when it ends up in the wrong hands? In any research involving humans or their data, the ethics committee assesses where the issues are. Associate professor at LIACS Suzan Verberne chairs the…

How do surgeons avoid causing nerve damage or leaving cancerous cells behind? An interdisciplinary research group at the LUMC hopes to improve operations and make them less invasive with the aid imaging techniques. They are working with medical companies to make these techniques widely available.

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.…

As technology transforms healthcare and services come under mounting pressure, one question remains the same: Will the advice or treatment offered help patients lead the lives they want to live? In her inaugural lecture, Professor Maxime Kummeling stresses the importance of quality.
