Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

The aim of the research presented in this thesis was to develop new methods forchallenging systems in liquid-state NMR using paramagnetic effects generated by thetwo-armed probe CLaNP-5.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

The department of World Archaeology combines research and education about regions all over the world, from Human Origins to the Middle Ages, and from Europe, to Asia, Africa and the America’s. That broad range in time and space makes the department a dynamic pluriform community with many different approaches,…

Analecta Praehistorica Leidensia 51

This research combines archaeological, archaeometric and ethnohistorical research to study the organisation of settlement space and residence rules among the Taino Indians during the Late Ceramic Age (AD 1000-1492).

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

Single-layer graphene (SLG) has attracted considerable interest as a proton exchange membrane for direct methanol fuel cells (DMFCs), owing to its atomic thickness, mechanical robustness, and unique proton permeability.

The Laboratory for Human Osteoarchaeology specialises in the macroscopic and microscopic analysis of human remains. We use cutting edge scientific approaches to address archaeological, historical, and anthropological research questions. In addition to paleopathological, histological, and 3D scanning…

Day-to-day activities are important in the development of social identities, the establishment of social standing, and the communal understanding of societal rules. This perspective is broadly referred to as practice theory and relates to the power of an overarching social structure and the individual…

The conquest by Rome brought profound changes to large parts of Europe. Unprecedented infrastructural works were created, towns sprang up, a ribbon of fortresses was laid out along the frontiers.

Since the emergence of humankind people have maintained social contacts and traveled widely, establishing interaction networks in which goods are traded and ideas are transmitted, increasingly on a global scale.

How do chemical contaminants traverse and affect terrestrial biodiversity and ecosystems?

The aim of the research project is to get insight in the biostratigraphical age and the palaeoecological setting of the Schöningen sites and hominin behavior and subsistence during the late Lower Palaeolithic.

A new study published in Archaeometry describes the unexpected results obtained from analyses of five human teeth discovered in a ritual cache at an enslaved African plantation site on the island of Saba in the Caribbean.

This project studies the roles of prehistoric foragers in past ecosystems to establish the character of past “natural” landscapes and enhance the management of current ones.

Death, fire and identity in North-West Europe

Band 69 | 2014

This study aims to provide a long time perspective of human landscape manipulation. Studying the roles of prehistoric foragers in past ecosystems is of great importance to establish the character of past 'natural' landscapes and to enhance the management of current ones.

How did persistent social inequalities first emerge? What cultural trajectories and institutions made this key development possible? How can archaeological inform us about the formation of class societies?

Dive into the heart of archaeological science: explore the flora and fauna of bygone ages, study human bones and teeth, analyse the cultural biographies of material objects, or become an expert in the use of digital data in archaeological research.

New sampling and analytical strategies give archaeologists a better understanding of the nutrition and survival of ancient populations. Publication in PLOS One.

What workflow of non-destructive techniques provides accurate, valuable data to improve our understanding of Caribbean archaeological landscapes? How were Amerindian settlements configured?

The bottom-up development of post-Roman northwestern Europe

PhD at the Max Planck Institute of Molecular Plant Physiology, Golm – Germany

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

Leiden researchers have developed a new method of determining the geographic origin of humans. Archaeologist Jason Laffoon and his team used the technique to discover where precolonial pioneers in the Caribbean region came from.

The Villa Son Sard archaeological project aims to determine the boundaries of the Roman and post-Roman villa at Son Sard on Mallorca. While the team was excavating in the summer of 2023, several news outlets covered the findings.

Fossil teeth can preserve remarkable information, much like a biological identity card with data about the lives of individuals tens of thousands of years ago. By analyzing teeth, a new study published in Science Advances reconstructed the life history of four straight-tusked elephants (Palaeoloxodon…

The distinguished academic journal Science published an article about an important and extensive series of measurements made by the Centre for Isotope Research (CIO) of the University of Groningen. The measurements concern the dating of a lake bed sediment in the Suigetsu Lake in Japan.

New research has revealed that one of Europe’s largest prehistoric mass graves records the deliberate killing of women and children, showing how gender- and age-selective violence was used to disrupt communities and assert power in the Early Iron Age. Leiden archaeologist Jason Laffoon was involved…

Dr. Josephine Joordens, post-doctoral researcher of the Human Origins Group, has been awarded a grant of EUR 15.000 to conduct fieldwork in the Turkana Basin, “the cradle of mankind”, in Kenya.

The European Research Council (ERC) has awarded a prestigious Starting Grant to Leiden archaeologist Dr Nathalie Brusgaard. With this €1.5 million grant, Brusgaard will investigate how the transition to farming in Western Europe affected the relationship between humans and wild animals. A theme that,…

Dr Nathalie Brusgaard both studied and finished her PhD at the Faculty of Archaeology in Leiden. After a few years spreading her wings, she is now back. As the new Assistant Professor in the World Archaeology department, she will continue her research on the relationship between prehistoric humans and…

Osteoarchaeologist Rachel Schats investigates traces of illnesses and disorders in human skeletons. Her search for malaria in the Low Countries' middle ages is central in an article in the Dutch version of National Geographic Magazine of February 2020.

Organisation of settlement space and residence rules among the Taino, the indigenous people of the Caribbean encountered by Columbus

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.

Until very recently malaria was an impactful disease in the Netherlands. While currently mainly regarded as a tropical disease, references to symptoms which could be related to the disease are found in several historical documents from the 17th century onwards. To be able to better understand this disease…

Osteoarchaeologist Rachel Schats investigates traces of malaria in old human skeletons. Even though the disease cannot be spotted directly in bone material, you may find traces of it, for example through porosity caused by anemia, linked to malaria. Rachel was a guest in the programme Science071 on…

Leiden Archaeology students may write their master's theses on the recently acquired collection skeletons from the city of Arnhem. We interviewed osteoarchaeologist Dr Rachel Schats, who is very happy with the news:

The Research Institute for Mathematics & Computer Science in Amsterdam hosts a unique X-ray machine that creates 3D scans of the most diverse objects. This allows them to reveal details that remain hidden in regular scans. In a series of articles they showcase examples of what happens in the lab. Leiden…
