The Institute of Biology Leiden (IBL) has a new professor: as of 1 March, Frederic Lens has been appointed Professor of Biodiversity and Anatomy of Plants. For Lens, the appointment feels like a wonderful recognition. ‘I am pleased with Leiden University’s appreciation of my contributions to research…

Amorphophallus decus-silvae, or the ‘penis plant’ as it is known, has just flowered at the Hortus botanicus. It flowered for two days, and then the pollen, which the male flowers produced was collected. As far as the plant experts at the Hortus can tell, this was just the third time that this species…

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…

The Netherlands is losing plant species that rely on pollination by insects. Leiden environmental scientist Kaixuan Pan demonstrates this after analysing 87 years of measurements from over 365,000 plots. The news is alarming for our biodiversity and food security. ‘75 per cent of our crops and 90% of…

The Plants & Planets exhibition brings two worlds together in a dazzling mix of science, nature and art. It opens at Old Observatory Leiden and Hortus botanicus on 7 February.

Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.

Plant biologist Pingtao Ding, assistant professor at the Institute of Biology Leiden (IBL), has received a 2.4 million European grant from the European Research Council (ERC). This ERC Starting Grant for promising young researchers allows him to unravel the molecular mechanisms by which plants resist…

Research on Asian plants is his life's work. Now a crown is added to that: a plant from the coffee family bearing his name. Paul Kessler is LUF professor of botanical gardens and botany of South East Asia and Scientific Director of the Hortus botanicus. 'Completely unexpectedly, you get to see the results…

Drained leaves and plants stripped bare. Insects can completely destroy crops. Soon, these situations may be behind us, with the new pesticide developed by Leiden and Wageningen researchers. With their plant-based ‘insect glue’, insects are incapacitated.

‘What I find most alluring about soil life is that you can steer it,’ researcher Martijn Bezemer of the Institute Biology Leiden (IBL) reveals. ‘You can ask: What do you want? And then I can transform the soil into something you need. At least, that is what we thought.’

For a few years now, Leiden’s Hortus botanicus has been mounting a campaign to cherish wild plants in the city – for the biodiversity and beauty of this spontaneous vegetation. Botanical artists reveal this beauty in an exhibition at Oude UB in Leiden.

PhD candidate Jianhong Zhou aimed to better understand whether and how plant species adapt to environmental changes. She developed two databases that she used to analyze how easily or difficultly plants adapt to changing conditions. Zhou defended her PhD thesis on 4 September.

The ‘Amorphophallus titanum’ at the Hortus botanicus Leiden is blooming. This Titan Arum, also known as the ‘giant penis plant’, last flowered in 2009.

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star at which planet formation has finished, while the same-aged companion star still has a planet-forming disk. The researchers…

What started with an old Soviet camera and a darkroom in London grew into a lifelong passion. Developmental biologist Michael Richardson has been capturing nature - from wild coastal plants to microscopic details in the lab - since his childhood.

A new study carried out by Leiden archaeologists Hadar Ahituv and Amanda Henry, together with international colleagues, reports the identification and analysis of 650 starch grains preserved on basalt percussive tools (anvils and hammerstones) found at an early Middle Pleistocene site in Israel. These…

Soil that is too wet, or too dry. Or with a lot or few nutrients. Due to climate change, the differences are becoming bigger, and plants must increasingly be able to adapt to survive. How do you make plants more stress-resistant? For this purpose, researchers from Leiden, along with other universities,…

Plants not only sense when they are touched, but they can also adapt to it. For example, by strengthening or defending themselves. But how do plants do this? The Green TE (Green Tissue Engineering) consortium has been granted a Gravitation grant of almost 23 million euros to investigate exactly this…

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…

National Meat Free Week (Nationale Week Zonder Vlees, 7–13 March) is an initiative to reduce meat consumption. Assistant professor Paul Behrens is studying what impact a change in our food consumption would have on the world. What, according to him, are the main reasons to switch to a (mainly) plant-based…

The Belgian elections are over. Now it is up to the formateur to form a cabinet, but that is difficult. Fauke Deceuninck, program leader of Politics and Governance at the Center for Professional Learning, explains to Speechmakers why that is.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…
