How can we find novel natural products from Actinomycetes that act as growth modulators on mammalian cells? Can we harvest and develop the potential of these novel compounds for industrial and medical biotechnology?

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

Archaic and Classical architectural terracottas constituted an integral part of the architecture of monumental buildings at Akragas. These objects therefore provide unique insights into the built environment of sanctuaries at this important Greek colony in Sicily. This research's multi-disciplinary…

Like any language, the natural sign languages of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that sign languages make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Like any language, the natural sign languages (henceforth: SLs) of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that SLs make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Sumerian is a dead language that is not related to any other language. Howeverr, Bram Jagersma managed to compile a grammar of the language, based on inscriptions and clay tablets. Traces of the Sumerian number system can still be seen in our sixty-minute hour. Jagersma received his PhD on 4 Novembe…

The Leiden Institute of Advanced Computer Science (LIACS) aims on doing applied research with partners. You can be involved in our research, and in the knowledge transfer of our research results.

This is an Erasmus+ International Credit Mobility project of Leiden University Medical Center with Boston Children’s Hospital in the USA.

The two-year programme is a challenging combination of general advanced courses, practical modules such as teaching assistance and conferences/workshops, a personal course profile, and research.

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…

The European Space Agency (ESA) introduces the members of the European Center for Space Law (ECSL) on its website through interviews with its members. One of those members is Tanja Masson-Zwaan.

On the 17th of January, Sarah Von Grebmer Zu Wolfsthurn successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Sarah on this achievement!

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Svetlana Gorshenina, Associate Lecturer at Collège de France, Paris, will be the Central Asia Visiting Scholar from 17 February until 25 February 2018. Svetlana Gorshenina will deliver a guest lecture on Tuesday, 20 February and a masterclass on Friday, 23 February within the Central Asia Initiative…

What are 'defects' and mechanical properties of mosaics of different shapes of tiles?

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

Patients share valuable advice and experiences with their peers in online patient discussion groups.

Organized by the Grotius Centre for International Legal Studies, this programme enables students and professionals from all over the world to engage in discussions on the prospects and challenges of international criminal justice. The announcement for the next edition is scheduled to take place…

The second and final report on the Netherlands‘ crime-terror nexus has analysed all fourteen profiles of individuals arrested in 2015 for offences of terrorism.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

The Mycenaean civilization of ancient Greek times offers enormous potential for useful information: from innovative construction methods to ways of handling crisis situations as a society. Archaeologist Ann Brysbaert and her team analyse Mycenaean construction processes in the ERC Consolidator project…

Leiden University archaeologists are reconstructing houses from the Stone Age, using only resources available during that period. This method offers surprising insights into the ingenuity of our distant ancestors, and challenges existing archaeological views.

Brain development in children with an extra X chromosome as compared to children with autism: evidence from MRI

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Plants could be regarded as small chemical factories, which produce chemical substances via photosynthesis. If we can imitate photosynthesis in an artificial system, we can make clean fuels and materials out of sunlight and CO2. Huub de Groot is very close to designing a system of this kind.

This summer school is for graduate (MA and PhD) students and researchers who have an interest in handwritten materials, editing, and the tradition of editing in the Muslim world. It offers theoretical lectures as well as hands-on practice with samples from the world-famous collections of the Leiden…

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

This thesis discusses the development in Proto–Indo–European, Latin and Romance of a word–formation pattern which the most adequate terminology in use dubs ‘verbal government compounds with a governing first member’; I use the shorthand ‘pickpocket compounds’.

Coming semester Karen Vet will be joining our team as the new intern. She has a BA in Middle Eastern Studies from Leiden University, specializing in Arabic language and culture.

The Dutch House of Representatives is deeply divided about the contested trade agreement between the European Union and Canada (Ceta). The economic figures are favourable in relation to Ceta, which has led to the removal of 98% of the import tariffs. Imports from and exports to Canada have both soared…
