Which molecules go into forming planets? PhD candidate Christian Eistrup and his colleagues have created new models to research this question. Their findings could change our idea of which molecules were forming Jupiter or even Earth.

The Sundanese people, the largest ethnic group in West Java, have been using traditional medicine for a long time. Known as ubar kampung, Sundanese indigenous knowledge, beliefs and practices of traditional medicine are based on local people’s knowledge and use of Medicinal, Aromatic, and Cosmetic (MAC)…

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…

For the first time in the Netherlands, an exotic insect species is released into the wild to combat a harmful plant species. The Japanese knotweed psyllid should offer relief against the rampant Asian knotweed. Suzanne Lommen of the Institute of Biology Leiden coordinates the field trials.

‘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.’

The entrepreneurial spirit is highly present among the SBB students. The many (successful) spin-off companies from Leiden University brought by (former) SBB students are proof of this.

A wide range of plant species is essential to our earth because of the different materials and foods these plants provide. But plant diversity has decreased drastically in recent decades. PhD candidate Kaixuan Pan explains what we can do to increase it once again.

A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

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.

Plants that are pollinated by fewer species of animal may be less vulnerable to change than was thought. This is what Saskia Klumpers discovered in the Rocky Mountains in Colorado. She will be awarded a PhD on 15 December.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

Leiden researchers have compiled information collected by scientists over the past 120 years into a database of plant-fungal interactions. This important biological data is now freely available for researchers and nature conservationists. Publication in New Phytologist.

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 different kinds of cultural perspectives on health and disease of the participants are related to their knowledge, beliefs, values and practices manifested in various forms of lifestyle in Indonesia. The cultural diversity of the population is also related to differences in health behaviour.

Can thrips resistance in strawberry be explained based on secondary metabolite profiles and plant morphological traits?

Early cave paintings of hunting scenes may give the impression our Stone Age ancestors lived mainly on chunks of meat, but plants were just as key to their survival. Plants rich in starch helped early humans to thrive even at the height of the last Ice Age, Leiden archaeologist Amanda Henry tells Horizon…

That a switching protein plays a role in protecting a plant from too much sunlight was already known, but how exactly was not yet understood. The research group of Anjali Pandit has now discovered that this protein changes shape when there is too much sunlight. The results have been published in Nature…

What chemicals do plants have available, and what happens if they use them when faced with bacteria or fungi? That is what PhD candidate Luis Salomé Abarca is keen to learn. He studies plants’ survival and their use of chemical components in communication and defence. Salomé Abarca works at the Natural…

Leiden scientists have discovered a new plant genus with two new species at a potential nickel mine site in Indonesia. Remarkable characteristic of the plants: they store manganese in their leaves.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

In September 2023, we will be transforming a under-utilised outdoor space into a greener and more biodiverse garden in which all students and staff of the Schouwburgstraat can relax and enjoy.

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

The project examines the political conflict in the Red River Valley of Louisiana between the majority-black Republican Party and the overwhelmingly white Democratic Party by studying the composition and actions of each party.

The Garden Club is a ProParte sub-group.

On Friday 10 July the Towards Biosolar Cells research programme was granted a budget of 25 million euros by the Dutch Government. The Ministry of Agriculture, Nature and Food Quality recommended the programme because it will contribute to green energy, improve food supplies and a create a more sustainable…

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…

Shell, our country's largest company, is constructing a vast plastics plant in the United States. And it is doing so at a time when the European Union, led by the Netherlands, is launching a major pact to combat use of plastic.

To generate electricity, power plants use huge amounts of water. In Europe and the United States, generating electricity is accountable for 40% of the total water withdrawal. PhD candidate Industrial Ecology Yi Jin devoted his research to the water footprint of power plants and the impact on the environment.…

For students who expect to graduate with a bachelor's degree in Law (LL.B.) from Leiden University before the starting date in…

In his report, Dutch cabinet negotiator Kim Putters proposes the formation of a ‘programme cabinet’ and an outline agreement. The four political parties involved have agreed on this form of cabinet, and Putters therefore appears to have succeeded in his mission. Wim Voermans, Professor of Constitutional…

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Shell, our country's largest company, is constructing a vast plastics plant in the United States. And it is doing so at a time when the European Union, led by the Netherlands, is launching a major pact to combat use of plastic.

Those pesky raindrops that get you wet on your way to work, are formed high up in the sky from clouds of water vapour. The process of nucleation describes the way this happens. Edgar Blokhuis of the Leiden Institute of Chemistry developed a theory to describe this transition more precisely. Chemists…
