Four scientists will receive the TOP grant for Physical Sciences from the NWO (Netherlands Organisation for Scientific Research). They are astronomer Ignas Snellen, mathematicians Tim van Erven and Charlene Kalle and computer scientist Siegfried Nijssen. The funds will be used to finance temporary research…

Dutch astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied “hot Jupiter” HD209458b. The very high-precision observations of carbon monoxide gas show that it is streaming at enormous speed from the extremely hot day side to the cooler night side…

Comprehensive, scholarly compilation of legal studies of substantive and procedural children’s rights, breaking new ground by analysing a wide range of international children's rights issues.

Archaeology is the only science that allows us to study the material traces left by most of human evolution. But what happens when we bring philosophy into the picture? A new series of papers demonstrates how philosophical reflection can enrich archaeological research - especially when grappling with…

PhD candidate Alex Brandsen, working in the Digital Archaeology research group has recently received a grant from the Leiden University Centre for Digital Humanities. This grant will be used to further develop and improve AGNES, the search engine for excavation reports that Brandsen is building.

The genetic material of currently living Europeans is partly of Neandertal origin. Were our ancestors successful because they were hybridising and interacting with the local populations they encountered when migrating into new places? Reconstructing our evolutionary trajectory is key for rethinking…

Alumna Nadeshda Jayakody (25) from Australia graduated cum laude in Human Rights Law. What did she learn in Leiden that has been most useful? ‘I had to pretend that I already worked for an NGO.’

Nederland ligt in de periferie van het verhaal van menswording. De evolutie van onze familie vindt lang exclusief in Afrika plaats. En, als Europa eenmaal bewoond wordt door mensachtigen, ligt het zwaartepunt ten zuiden van onze streken. Toch heeft ons land een aantal interessante vindplaatsen en vondsten…

The aim of this work was to develop a transgenic (TG) Balb/c mouse model for evaluating the immunogenicity of recombinant human insulin (insulin)…

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…

uman skin equivalents (HSEs) are in vitro 3D-skin models that mimic many aspects of the native human skin (NHS) and can be a valuable tool.
