Archaeologist Mette Langbroek works on beads exhibition: ‘Humans have a special relationship with beads'
Beads are among the oldest types of human artistic expression. Even so, the small ornaments have a bad status record regarding archaeological investigation. PhD candidate Mette Langbroek, usually at home studying early medieval beads, had the opportunity to work on a publication and exhibition on 5000…

Personal ornaments: changing identities in the Dutch Neolithic and Bronze Age
Numerous beads and pendants of amber, jet and bone have been found in Dutch Neolithic and Bronze Age context, both in settlements and in graves. Because ornaments are personal items, they are closely linked with people’s identity.

Seascape Corridors: How modelling routes through the sea can illuminate early island culture
What are the capabilities or limitations of traveling between islands and how does this reflect seasonal variation? Is it possible to show higher levels of connectivity between islands based on generated pathways between several sites on two separate islands?

Photocleavable activity-based acid glucosylceramidase probes
Lysosomal acid glucosylceramidase (GBA1) is a lysosomal enzyme that degrades glucolipids with its main substrate being glucosylceramide (GlcCer). Defects in the GBA1 gene lead to glycosphingolipidosis Gaucher disease (GD), in which the hydrolysis of GlcCer is impaired and therefore, it accumulates in…

The Role of Linker DNA in Chromatin Fibers
The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

Why do birds flock? Shedding light on collective motions in heterogeneous populations
Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

Can we live longer? Leiden physicist makes discovery in protective layer in genes
With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

DNA folded in compliant helix
In an Advance Online Publication biophysicist John van Noort and others show using magnetic tweezers that DNA is folded in compliant helices of chromatin. This allows enzymes access to the DNA needed for gene expression. Van Noort's research group made the discovery in close partnership with researchers…

How our single-celled relatives package their DNA
A group of single-celled organisms organises its DNA in a similar way to higher organisms such as plants, animals, and fungi. However, the way packaged DNA is read out differs between the two related groups, Bram Henneman discovered. PhD defence on 5 December.

How microscopic scallops wander
All microscopic objects, from enzymes to paint particles, are jittering constantly, bombarded by solvent particles: this is called Brownian motion. How does this motion change when the object is flexible instead of rigid? Ruben Verweij, Pepijn Moerman and colleagues published the first measurements…

How cells talk by pulling on a fibre network
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…
