As part of the euCONSENT consortium, the Center for Law and Digital Technologies (eLaw) has been awarded European Commission funding to create a child rights’ centred cross-border system for online age verification and parental consent.

Simone van der Hof, professor of Law and Digital Technology at eLaw, has joined the EU Special Group on Code of Conduct for age-appropriate design as an expert.

On 7 October 2021 Simone van der Hof participated in an online talk show as part of the Dutch Media Week. The theme was the research project she is working on with Tony van Rooij of the Trimbos Institute and Max Birk of TU Eindhoven: Behavioral Design in Video Games.

Mums posting photos and videos of their child on Instagram and TikTok and also earning loads of money doing so. Kidfluencers, momvloggers and familyvlogs are very popular, in the Netherlands too. But the lack of legislation regulating these activities means that these children are barely protected.…

Is aggression always bad? PhD research by psychologist Simone Dobbelaar shows that it is not. In fact, children who occasionally fiercely defend themselves and stand up for their peers often feel better mentally.

Political scientists study topics that affect society, but their work often remains out of the spotlight. Not always: the research of Leiden political scientist Simon Otjes does have a visible impact.

Children have the right to play and relax. Games, social media and video platforms are attractive new ways to do that. However, hardly any online games are designed specifically for children, nor do they factor in children's rights.

How do animals choose their partners? The answer is simple: it’s all about quality. While humans tend to wear clothes that happen to be in fashion, animals do nothing without a reason. Behind beautiful plumage or a deafening roar is only one message: I am in great shape. The evolutionary courtship displays…

I suggest a systematic study into the influence of non-singing female companions on vocal learning in young birds as a proof-of-principle study into how non-imitative learning processes from the social environment influence the timing and content of vocal learning and thus drive the interface between…

I am passionate about aquatic ecology, conservation and evolution, behavioural biology and global change. During my PhD, I am investigating the density and diversity of pelagic fish in and around offshore windfarms in the North Sea, more specifically related to the underwater acoustic conditions. This…

The incLUsion programme offers refugees who are not yet able to enrol as regular students the opportunity to take part in university education. Simon (IncLUsion secretary) and Sharon (exchange officer) reflect on the graduation and explain how the programme works.

The many thousands of small celestial bodies beyond Neptune’s orbit may have ended up there due to a star that passed close to the solar system billions of years ago. This is shown by Leiden simulation expert Simon Portegies Zwart, along with his German and Dutch colleagues. ‘We are answering several…

De Code voor Kinderrechten op het internet toont makers van apps en games hoe zij de rechten van kinderen kunnen beschermen en meenemen in hun ontwerp.

Recent studies have shown that Dutch secondary school pupils experience a great deal of stress from school work, and between 2001 and 2007 the number of adolescents experiencing school stress even doubled. The study carried out by Simone Vogelaar focuses on stress factors and the effectiveness of the…

Hans Slabbekoorn is specialised in animal sounds. On 1 July, he was appointed professor of Acoustic ecology and behaviour. A great honour, according to the new professor. ‘This job never gets boring, whether I am investigating the urban jungle or marine noise.’

Hans Slabbekoorn researches animal sounds and the effect of the noise we humans make on these animals. He is also committed to making his discipline more diverse.

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the emerging field of quantum acoustics.

'Engaging With Everyday Sounds' is a rich and inspiring exploration of the role of sounds in everyday life, including their impact on human actions, emotions, and imagination. Marcel Cobussen intertwines sonic studies with philosophy, sound art, sociology and more to create an impressively lucid and…

The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic.
