X-ray and CT scanners are widely used devices in research, diagnostics and the industrial sector. And yet they are not nearly as fast and accurate as we would like. Mathé Zeegers is researching the newest technique in the field at the Centre for Mathematics and Computer Science: spectral X-ray imaging.…

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.

Assistant Professor Karlsson Linnér, who works at the Department of Economics, is one of the recipients of a Veni grant. His research on the accuracy of preventive genetic testing is a fine example of the intersection of economic science and law.

An X-ray scanner, some small metal balls, and a newly developed algorithm. That is all you need to make a 3D model that enables you to look inside art objects without dismantling them. Thanks to the research of Francien Bossema (Centrum Wiskunde & Informatica and Leiden Institute of Advanced Computer…

An atomic vandal has finally been caught! Scientists from Leiden University and the Department of Energy’s SLAC National Laboratory have uncovered the mysterious cause behind the rapid corrosion of platinum electrodes. This breakthrough paves the way for more affordable green hydrogen production and…

A European team of astronomers, led by Leiden-based researcher Konstantinos Migkas, has uncovered a large filament — a long, thread-like structure — of hot gas connecting four clusters of galaxies. This filament is made up of what scientists call the warm-hot intergalactic medium.

The Research Institute for Mathematics & Computer Science in Amsterdam hosts a unique X-ray machine that creates 3D scans of the most diverse objects. This allows them to reveal details that remain hidden in regular scans. In a series of articles they showcase examples of what happens in the lab. Leiden…

Exploring the largest structures in the universe by looking at the tiniest particles? Lydia Stofanova, PhD candidate at Leiden Observatory and SRON Netherlands Institute for Space Research, dives into this intricate connection. In her PhD research, she explored how elements like oxygen influence the…

In donut-shaped buildings, particle accelerators take super-detailed X-ray images. Yet those images are not good enough to learn how to drive on hydrogen for example. Mathematics PhD student Allard Hendriksen has developed an algorithm that improves the images without having to learn from data from…

The university finds it important that students and staff are offered a safe environment. Read here about the safety measures in place and what you should do in case of emergencies or other incidents.

An international team of astronomers led by Matus Rybak (Leiden University) has proven, thanks to accidental double zoom, that millimetre radiation is generated close to the core of a supermassive black hole. Their findings have been accepted for publication in the journal Astronomy & Astrophysics.

In the course of 2020 the Faculty of Archaeology was bolstered by some new staff members. Due to the coronavirus situation, sadly, this went for a large part unnoticed. In a series of interviews we are catching up, giving the floor to our new colleagues. We give the floor to Dr Martin Berger, who joined…

What do you do if you have a book from the sixteenth or seventeenth century, but you suspect that the binding contains a fragment of a medieval manuscript? University lecturer Thijs Porck has received an NWO grant to experiment with a camera attached to a tube. 'The project boils down to keyhole surgeries…

Nadine Akkerman, associate professor of early modern English literature is receiving the Dr Hendrik Muller Prize 2021 for her work.

Nano-plastics cause malformations. Meiru Wang, researcher at the Institute of Biology Leiden, looked at the extreme effects polystyrene nano-particles could have, using chicken embryos as a model. Her results were quite alarming. Especially as nano-particles are everywhere. In the air, floating through…

50 years ago Lauterbur published the basic principle of MRI. Sine then MRI has become more expensive. Professor Andrew Webb describes what is needed to make MRI available for everybody.
