Legal protection. What do those involved in youth care and child protection understand by this concept? And what needs to change to improve legal protection? This question was explored by researchers from Leiden University’s Department of Child Law. Their research fits with the government’s ambition…

Animal species that are dear to us in the Netherlands often spend a large part or all of their lifecycle in other parts of the world. But their habitats worldwide are under increasing pressure, are often inadequately protected and much poorer than the global average. ‘If we truly care about these animals,…

Over the past few years, citizen scientists from the Heritage Quest project have scoured the entire Veluwe and Utrechtse Heuvelrug areas for unknown archaeological heritage. One of the results of this research is that the number of known burial mounds in this area has doubled.

The new Erfgoed Gezocht/Heritage Quest website means you can play armchair detective and hunt for undiscovered burial mounds in the Veluwe. This will help stop them being destroyed by construction projects. The website is the initiative of the Leiden University Faculty of Archaeology in collaboration…

The annual LION Image award goes to the 30 micrometer long 3D printed microboat image that went viral earlier in October 2020, submitted by Rachel Doherty of the Daniela Kraft lab.

Neanderthals were able to make fire on a large scale with the aid of pyrite and hand-axes. This means they could decide when and where they wanted fire and were not dependent on natural fire, as was thought earlier. Archaeologist Andrew Sorensen has discovered the first material evidence for this. Publication…

Wouter Verschoof-van der Vaart is refining an artificial intelligence system that can detect and classify archaeological objects on digital images. Such a system is desperately needed because human archaeologists around the world are being flooded with data.

The doctor suggests opting for a treatment that is better for the environment. How do patients react to this? Doctors and psychologists together discovered that this has little impact on patient confidence in the doctor.

The COVID-19 pandemic and associated measures during the first lockdown in the Netherlands in March 2020 caused major changes in daily life. Parents worked from home and children followed school online. Therefore, the families were forced to spend more time together. This is particularly difficult for…

In medical and psychological sciences, little research has been specifically conducted on women. Hormonal fluctuations were considered too intricate. Yes, research into sex and gender differences is complex, acknowledge neuroscientists Ellen de Bruijn and Lara Wierenga, but that’s precisely why it's…

Child marriage has become an increasingly important topic on the international human rights and development agenda. Many organisations are calling for a ban, but what problem would such a ban solve? PhD defence on 18 March 2020.

In March 2022, a considerable number of non-Western countries abstained (35) or voted against (5) a resolution deploring Russia’s aggression, its violation of the UN Charter and demanding the withdrawal of its forces from the territory of Ukraine.

This event, co-organised by the Intelligence and Security Group and the…

What do ten-year-old children and chatbots have in common? PhD researcher Bram van Dijk studied language development in both children and AI language models. ‘It’s actually quite practical that we attribute human traits to a chatbot.’

Climate change, biodiversity loss and environmental pollution are urgent problems that call for close collaboration between lawyers and scientists. Dr Hilde Woker and Dr Jason Rudall, both Assistant Professors at Leiden University, are investigating the important interface between law and science.

On 16 May, three researchers from Leiden University will present their findings on the democratic consequences of decentralisation at a workshop in Leiden.

LUC historian Jacqueline Hylkema unmasks forgeries from the early modern Dutch Republic in the research project

Remote teaching: reality until at least the end of this academic year. The transition to remote teaching required a huge effort and adjustments from all staff. So what’s it like for Leiden Law School’s lecturing staff? Three colleagues tell us about their first weeks of experience with remote teachi…

How has evolution shaped our curiosity? And how does that curiosity ensure that we now have the technological ability to discover whether we are alone in the universe? This was all covered during the celebration of Leiden University’s 449th Dies Natalis.

It is undeniable that the public is central to the practice and study of public diplomacy. Indeed, this field is known as *public* diplomacy.

‘Foreign policy’ may seem to the general public to be merely an official response to problems entering the nation from across the border. Yet the political reach of diplomacy has extended, and diplomats will have to find ways to engage more with home citizens, including those who feel sidelined and…

He tells about his research and how this helps make a useful quantum computer a reality a little bit sooner. ‘I hope I will get to see quantum computers contributing something really…

How do religious narratives persuade their readers to believe their message? And how can it be that some readers even come to treat fantasy and science fiction as authoritative religious texts? These are the core questions treated in Markus Davidsen’s new book Narrative and Belief: The Religious Affordance…
