Building with flexible blocks
On an apparently normal cube a pattern of hollows and bulges appears when the cube is compressed. A method has been developed to design such three-dimensional structures and to construct these using simple building blocks. Publication in Nature.

Tiny clumps recycle themselves into complex structures
Manufacturers produce high-end technology mostly top-down with large machinery, but small particles are able to build structures by themselves from the bottom up. A major challenge is that these particles easily clump together. Leiden physicist Daniela Kraft has developed a method to use this phenomenon…

Why not sing? Reconstructing the evolution of female and male bird song
Female and male songbirds sing equally elaborate songs in some species, but in others, females do not sing like males or not at all. How did such pronounced differences in male and female communication evolve?

Skin Deep? Reading the Surfaces of the Body in Ancient Greek Literature and Science
The skin has recently gained attention within body studies for its many specific cultural and social associations, in addition to its biology. This project aims to examine the different layers of meaning and the functions invested in the skin in ancient Greece: how did ancient Greek literary and medical…

Triple Bioorthogonal Ligation Strategy for Simultaneous Labeling of Multiple Enzymatic Activities
Three at the same time: a ligation strategy combining tetrazine–norbornene cycloaddition, Staudinger–Bertozzi ligation, and copper(I)-catalyzed click reaction was used to label the three catalytic activities of the proteasome simultaneously in a single experiment. The orthogonality of the three ligation…

Protein condensates as Materials
We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

Fires, Food and the Evolution of Human Detoxification Capabilities
A study by a Leiden-Wageningen group shows that present-day humans are biologically poorly equipped to deal with the toxins they are regularly exposed to in smoky environments: compared to earlier hominins, we modern humans are probably even worse off. The study appeared in Molecular Biology and Evolution.…
