Food
The research within the Food research programme at CML focuses on a transition towards sustainable food production and consumption systems. We investigate from a very small to a very large scale, at a local, national or international level. We do so by researching for example molecular tools, food systems,…

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…

Asynchrony among plant communities stabilises ecosystem
Fluctuations in individual plant communities contribute to the stability of an ecosystem as a whole, a study published in Ecology Letters shows. Nadia Soudzilovskaia and colleagues for the first time used data from plant communities across five continents to prove this hypothesis.

New light on innate plant immunity
Plants are able to resist a pathogen’s attack by a dual innate immune system. The relationship between the two pathways was not clear, but it turns out that they mutually potentiate each other, as assistant professor Pingtao Ding (Institute of Biology Leiden) and colleagues (The Sainsbury Laboratory,…

Improving vegetation representation in Multi-sensor Earth Observation Products through phenology and trait-based priors
What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

Remote participation in a hybrid classroom: Interacting with students with chronic illnesses
There are about 35,000 students with chronic illnesses in the Netherlands. If they cannot receive education in the classroom, they may be able to do so from home or a hospital with hybrid education. The question in this study is: how can interaction with the teacher and fellow students be promoted?

Tessa Verhoef: 'An algorithm still has a lot to learn from human interaction'
If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

Modelling the interactions of advanced micro- and nanoparticles with novel entities
Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.
