The CollAction team brought the historical Herbarium collections into top condition. The old covers were replaced by the team with new acid-free covers. This way, the collection will last for multiple generations.

Today, an international public-private partnership of eleven forward-thinking academic and private organisations announces its joint effort to establish the Leiden Institute for FAIR and Equitable Science (LIFES). The founding partners of LIFES are the GO…

In May, the CollAction team inventoried more than 50,000 botanical slides from Wageningen University & Research. These are mostly photographs of plants in the field or in greenhouses. The team selected 3,000 slides to be included in our collection. These…

A 3D model of imitation blood vessels will make it possible to see exactly how snake venom attacks blood vessels, without having to use laboratory animals. This new research model, called an organ-on-a-chip, was developed by a research team from Vrije…

Cave lion, brown bear, aurochs: they all could be found in the Netherlands, once, long ago during the Ice Age. The CollAction team didn't know that, but now we pass the skulls, bones, teeth through our hands every day, as we neatly store their fossils.

The CollAction team was deployed to transfer about 120,000 Apollo butterflies to standard drawers. This work allows these butterflies to be used in science. During this task, the CollAction-team quickly encountered some surprises.

Much of the mollusc fossils in Naturalis' collections are stored in liquid, namely silicone oil. This was done to prevent or stop damage to the fossils. Part of work of the CollAction team was to check for damages in the mollusc fossils collection.
