Living Labs and ‘pavement plants’: Leiden University’s contributions to biodiversity
Through various initiatives, Leiden University is trying to make people aware of the importance of biodiversity: the cultivation of a wide variety of micro-organisms, animals and plant species. This is important because in the Netherlands biodiversity has declined from about 40 percent in 1900 to about…

Hoe meer tijd, hoe beter de nier
Donororganen zijn er nooit genoeg. De organen die wel beschikbaar zijn, moeten vliegensvlug getransplanteerd worden. De geneeskunde zet daarom volop in op het langer goedhouden van organen. Marlon de Haan (24) onderzoekt hoe je nieren buiten het lichaam in leven kunt houden.

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…

Antibiotic resistance: an economic problem universities could help to solve
Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.

Hooray! This extremely sensitive microscope survived its relocation
Moving an electron microscope of 2000 kg is a delicate challenge. The highly sensitive instrument needed to be moved to a new measurement hall, but even a tiny bump could damage it. After a few nerve-racking weeks of preparing the move and reinstalment, the researchers finally have a verdict: the instrument…

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…
