patterning in movable Latin type : Renaissance standardisation, systematisation, and unitisation of textura and roman type
This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

Chemical tools to study the cannabinoid receptor type 2
The cannabinoid receptor type 2 (CB2R) is associated with several inflammatory diseases with an unmet medical need (e.g. Alzheimers, multiple sclerosis, reumatoid arthritis). Development of new chemical biology strategies to study this protein is essential to aid future development of drugs for these…

Football is simple. What is difficult is playing simple football.
And that is what scientist Rens Meerhoff of the Leiden Institute of Advanced Computer Science (LIACS) explains in the NPO Radio 1 programme Focus. He researches football tactics on the basis of position data of footballers and charts how physically and mentally fit a footballer is. He also explains…

Tracing cancer with a simple blood test
Thanks in part to the persistence of a Leiden research group, cancer could be detected in the near future with just a single drop of blood. Not only can the diagnosis be determined at an earlier stage, but the blood test is also cheap, fast and patient friendly. The first results of this method seem…

Sea sponges may seem like simple creatures, but…
One of them turned out to be two thousand years old. And older giant barrel sponges appear to have a faster rate of cell division, unlike us. They produce antibiotics and much, much more. Lina Bayona Maldonado studied how the differences in such factors as age or oceanic depth affect the production…

Designing better catalysts using simple chemical concepts
An international team of researchers, including Federico Calle-Vallejo of Leiden University’s Institute of Chemistry, have taken the atomic-scale design of catalysts to the next level. Their research contributes to the quest for a method to generate or store energy more efficiently. The report is published…

understand the excess baryonic mass in the centres of high-mass, early-type galaxies
This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

There is not one type of refugee
What is a refugee? This question might seem easy to answer, but it is not, concludes Catherina Wilson. For 7 years she did research in The Democratic Republic of the Congo near the Ubangi river, on refugees from the Central African Republic. The research shows that among refugees there exists a wide…

Leiden scientists map cell types in fetal kidney
Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

Ten thousand types of plant outgrowths bundled
For nine years he worked on the three-volume standard work Plant Galls of Europe. It yielded 2300 pages about 10,000 species of European galls, abnormal outgrowths in plants caused by parasites. Hans Roskam from the Institute of Biology Leiden: ‘The abundance of galls says something about the natural…
