How do you set up a successful collaboration between science and practice? That was the main theme of the final meeting of a triptych of symposia on how Leiden University can improve inter- and transdisciplinary collaboration.

It’s better to cut our nitrogen emissions now than to solve the consequences later at great expense. That’s the lesson we can learn from the Dutch nitrogen crisis, according to nitrogen expert Jan Willem Erisman. In Science, he shares this lesson with other countries. According to Erisman, we should…

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

This is a facility where research groups or small companies can apply for space if they need to culture human or animal cells.

Increasing above- and belowground biodiversity in arable leek cultivation to stimulate pest control by natural enemies.

Criminal Justice as a concept refers to the system of practices and institutions of governments directed at upholding social control, deterring and mitigating crime, or sanctioning those who violate laws with criminal penalties and rehabilitation efforts. While the definition seems rather clear-cut,…

The polypept(o)ide hybrid material attracted more and more attention over the past decade by combining the multifunctional characteristics of polypeptides with the shielding characteristics of polypeptoid-pSar possessing similar properties as a shielding material as polvethylene glycol(PEG). Polysarcosine…

OBJECTIVES: To determine whether the lipid/protein ratio and the total dry SC mass per surface area are related with the skin barrier function of controls and AE patients.

Through the clever use of two types of telescopes, a team of researchers has produced stunning images of clusters of galaxies. This not only produces beautiful images, but also provides more information about the enormous amounts of energy released around supermassive black holes in clusters. The astronomers,…
