Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

Mechanics play a larger role in blood vessel formation, and other developmental biology, than previously thought. Cells appear to respond to mechanical signals, such as pressure. Through the extracellular matrix, a network of fibrous proteins, cells can supposedly exchange those mechanical signals over…

The perfect ship is light and sleek for speed, but also needs to be strong and stable for safe sailing. These and other conflicting requirements make it difficult, even with a supercomputer, to find the ideal design. Computer scientist Roy de Winter has developed an algorithm that helps strike the perfect…

It's time for the 2021 Image Award

The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…

The right medicine in the right dosage for every patient, that is something medical science aspires. 'Personalised medicine' is the term for that. But it does require a lot of research with patient data and that can be hard to get due to privacy legislation. Researchers Laura Zwep and Coen van Hasselt…

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.
