Adults are more likely to reoffend after a short prison sentence than comparable adults with a non-custodial sentence, Leiden University research shows. This is true for the likelihood and extent of repeat crime.

Roderick Bouman is collection manager of the Leiden Hortus botanicus. He keeps track of which plants there are in the garden, where they come from and makes sure visitors can find the right information about them. ‘We are like a regular museum,’ says Bouman. ‘Except that our objects are alive. That…

Botanisch filosoof Norbert Peeters vertelt over hoe mensen omgaan met planten in het algemeen, en met onkruid in het bijzonder.

Leiden researchers, Professor Remko Offringa and co-applicants Salma Balazadeh and Frederic Lens received an NWO-XL grant (2.5 million euros). Together with researchers in Wageningen and Groningen, they will study the genetic and environmental drivers of woodiness. From plant to molecule, the groups…

An international research team is to search for invisible life in the Galápagos Islands. The diversity of bacteria and other microscopic organisms may not be evident to the naked eye, but it is essential to nature. To the islands' giant daisies, for instance: unique endemic plants that are currently…

The number of insect species is plummeting, which is why the University is creating a more biodiverse environment around its buildings. Annetje Ottow, President of the Executive Board, planted the first bee-friendly plants in the front garden of Oude UB on 20 September.

Salma Balazadeh, Víctor Carrión, and Jos Raaijmakers, biologists at the Institute of Biology Leiden (IBL), have successfully applied for an NWO grant and got awarded 730.000 euros. The board of NWO Domain Applied and Engineering Sciences awarded funding for their project within the Open Technology Programme…

In the tropical rainforests of Southeast Asia the soursop family (Annonaceae) can be found. The genus Uvaria is a part of this family, but it has not yet been described entirely correctly. That is what Annas Rabbani will be studying during the next four years as a PhD student at the Hortus botanicus…

What is the best way to restore dune ecosystems? The project TERRA-Dunes researches the role of soil microbes in the development of natural dune areas. Recently, the project went into a new phase: planting 412 oak seedlings grown in different type of soils.

Whether a microbe is beneficial or harmful to a plant can now be predicted with high accuracy thanks to bacLIFE. This bioinformatic tool with an intuitive interface makes it much easier to unlock the secrets of bacterial genomes. A group of Leiden biologists presented it in Nature Communications.

One of the largest roofs at Leiden University, that of the Snellius building, has recently been equipped with 590 solar panels and 57,000 sedum plants, making it the largest combined roof in the Benelux. The roof was officially opened on Monday 10 October by Annetje Ottow and Martijn Ridderbos, President…

Five researchers from Leiden University have been awarded a Starting Grant by the European Research Council (ERC). This grant of on average 1.5m euros enables researchers who show potential to start their own project, lead a research team and implement their best ideas.

A plant-based diet could improve the resilience of our food system. Moving to such a diet in the European Union (EU) and United Kingdom (UK) alone could replace almost all the production losses from Russia and Ukraine. That’s what an international team of researchers conclude in Nature Food. Leiden…

Is polder rice a feasible circular alternative to cows on peat soil? In May, an experimental trial began, with researchers from Leiden University and Wageningen University & Research (WUR) planting around 3,000 rice plants at the Polderlab near Leiden. The researchers aimed to test rice as a middle…

Martijn Verkuilen is the winner of the Unilever Research Prize 2022. By transferring DNA from a plant into yeast, he made the first move to produce a new drug for type 2 diabetes. He collected his prize in Wageningen on 24 November.

In 2011, Dr. Amanda Henry published her findings from dental plaque picked from the teeth of Neanderthals who were buried in Iran and Belgium between 46,000 and 40,000 years ago. Plant microfossils trapped and preserved in the hardened plaque showed that they were cooking and eating starchy foods including…

The plane trees from the forecourt of Cluster North have been moved to the Herta Mohr building (Cluster South). The trees could not remain in their original location because of the forthcoming renovation of Cluster North. They have been moved already in advance of the flowering season. In June, the…

The Rob Schilperoort Memorial will be unveiled at the Leiden Bio Science Park on Saturday 16 September. This gigantic gate stands at the entrance to the park, which is also named after Schilperoort, its founder.

A lot of green, corners to sit in and paths to stroll along. These were the wishes for the restyling of the garden of the Huizinga building. After some forty years, it was time to give the garden a facelift. The result is a welcoming, green garden with sunny spots and shaded nooks.

Four green research institutes in Leiden are joining forces to integrate evolution and biodiversity research, at local and at the national level. Pivot in this collaboration is Frederic Lens.

Op zaterdag 3 juni vindt de Museumnacht Leiden plaats. Ook dit jaar zijn Leidse wetenschappers en studenten onderdeel van de programmering.

Starting September 2024, Amanda Henry has started a new role as Professor by Special Appointment on the Evolution of the Human Diet at Naturalis Biodiversity Center in Leiden. She will use this position to draw closer ties between the Faculty of Archaeology and Naturalis, and explore means for public…

Thijs Bosker, Associate Professor of Environmental Sciences at Leiden University College (LUC) and the Institute of Environmental Sciences (CML), has received funding as part of a large consortium to study the impacts of microplastics on agricultural soils. The project will receive 7 million euro of…

The daisy has been crowned the Netherlands’ national flower. Rogier van Vugt, Head of Horticulture at the Hortus botanicus, explains why the daisy merits its elevation to national symbol.
