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.

Promotor: Prof.dr. L.J. Slikkerveer

Plants love favourable microbes such as bacteria and fungi: they grow better and become healthier. Jos Raaijmakers, Professor of Microbial Ecology, is in search of the right microbes to be used in agriculture. Inaugural lecture 13 November.

The arrival of Columbus to the Caribbean in 1492 marked a milestone in world history. In both the European and the indigenous world, a set of economic, political and hierarchical networks and relations were defined, structured and changed. These changes affected the indigenous population at different…

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…

A functional study of chert artefacts from preceramic sites in Colombia (2002)

‘Qasr Bshir is magnificent even in decline. It sits majestically in the landscape, master of all it surveys. On approaching the site, however, it is clear that the structure is damaged’, states the latest issue of the journal Current World Archaeology.

From one year to the next, face masks have started to appear in the environment. As the masks are discarded, they end up in the top soil, in sediment layers, and in refuse heaps. In a couple of generations archaeologists will study the layer that has already been labeled the Face Mask Horizon. Current…

Direct radiocarbon dating of human remains is crucial for the accurate interpretation of prehistory. Yet given the scarcity of prehistoric human remains, direct dating is often too destructive for important fossils. The reduction of sample size necessary for dating bone is therefore of great interest…

Emeritus Professor Ben Lugtenberg edited a book on “Principles of Plant-Microbe Interactions” together with Paul Hooykaas, Eddy van der Meijden and Jos Raaijmakers, all from the IBL.

The journey of sugar from east to west

Dr Bleda Düring deemed it was time for an archaeological approach on the imperialisation of Assyria. ‘While there are lot of archaeological studies of Assyrian sites, they are not really trying to address this broader picture of imperialism and how this imperialisation actually worked.’ These imperialisation…

Archaeologist Natalia Donner has been awarded a grant of €5,000 from the Bakels Fonds for her research Bridging the Gap: a historical ecological approach to human practices in the Darien Province, Panama. She will use this grant to conduct the first systematic archaeological survey in the region.

A multi-disciplinary approach to past lifestyles and cultural practices

The funerary textile tradition from the Osmore Valley, South Peru, and its social-political implications (2005)

Just like us, plants also produce growth hormones, and they also go through an ageing process. The study of the genes and mechanisms behind these processes is useful not only for crop breeding and agriculture, but also for medical research. That is the view held by Professor of Plant Developmental Genetics…

A Functional Analysis of Pre-Columbian Shell and Stone Artefacts from Anse à la Gourde and Morel, Guadeloupe, FWI

Restoring a natural plant environment on exhausted agricultural lands and in nature areas is difficult. We can speed this up by steering the soils towards the desired situation. This is what Martijn Bezemer, newly appointed Professor of Ecology of Plant-Microbe-Insect interactions at Leiden University’s…

Pastoralist Societies, Rock Art and Literacy in Jordan’s Black Desert (200 BC to 800 AD)

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…

Commagene in its Local, Regional and Global Hellenistic Context

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,…

Ceramics and Society in the Aegean from the 7th to the 20th century A.C. A Case Study from Boeotia, Central Greece (2003)

BA 3 student Dasha Derzhavets is one of the first students to be back in the lab at the Faculty of Archaeology. She is conducting experiments in the ceramic and experimental lab for her thesis. ‘It is different in the labs, a lot quieter, I can better concentrate on my work however.’

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.

The Global Strategy for Plant Conservation, a world-wide effort by the botanist and plant protection community, is making considerable progress in protecting plant diversity around the world, a new report says. The Hortus botanicus Leiden is one of the partners of the project.

The production, use, and exchange of bodily ornaments through the lenses of the microscope

This dissertation presents a legal geographical analysis of the heritage laws of the independent English-speaking islands of the Lesser Antilles.

The historical archaeology of the Port of Sandy Point and its anchorage, St. Kitts, West Indies

On January 17th 2023, Caterina Ghini, Ambassador of Greece to the Kingdom of the Netherlands, visited the Faculty of Archaeology. Her Excellency reached out to Leiden University with the purpose to collaborate and engage with us.

As part of Nexus 1492 Subproject 4: A Future for Diverse Caribbean Heritages, which seeks to shed light on how local communities interpret and engage with heritage in the present day, this doctoral study aims to gain insight into how indigenous heritage is represented in the school curriculum for social…

Producing offspring of a crop without sowing and that is even bigger than the parent plant. According to Leiden researchers this can be achieved by overstimulating a single gene that rejuvenates cells, including bringing them back to the embryonic phase.

In the spring of 2024 the Faculty of Archaeology welcomed a new postdoc. Dr Adam Benfer, originally from the United States, occupies a double position as a researcher in the project of Alex Geurds and as the Faculty’s Data Steward. ‘It is pretty much what the title says: I steward data. Essentially,…

A plant that takes metal from the ground all by itself: a natural way to mine or to clean the soil. PhD student Roderick Bouman (Hortus Botanicus Leiden) described a new plant species from Sabah, Borneo, which can be used to extract nickel. In an open access article in Botanical studies, he and the…

The Caribbean before Columbus is a new synthesis of the region’s insular history. It combines the results of the authors’ 55 years of archaeological research on almost every island in the three archipelagoes with that of their numerous colleagues and collaborators.

There is little evidence of the routes connecting Amerindian communities in the Caribbean prior to and just after 1492. Uncovering possible canoe routes between these communities can help to explain the structure, capabilities, and limitations of the physical links in their social and material networks.…

On February 4th standing before his doctoral committee at the Leiden Faculty of Archaeology, St. Kitts-born Cameron Gill, successfully defended and received his Doctorate.

Update : August 2017 Dr Harco Willems

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…
