Proving a quantum computer to be quicker than a normal one is one step closer. After a breakthrough in speeding up classical algorithms, researchers Vedran Dunjko and Casper Gyurik showed that only one quantum algorithm could beat its classical counterpart. They discuss their discovery in Quanta Mag…

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

Do you recall all those drugs that were hastily proposed as potential treatments for COVID-19? In the event of a future pandemic, the goal is to offer an effective treatment more quickly and efficiently. To achieve this, a team led by Coen van Hasselt is developing a platform that can speed up the process…

Many parents whose children have been placed in care do not understand the basis on which the decision was taken. Dutch youth protection organisations and the Child Protection Council must better document why they request such a measure from the Juvenile Court.

Search engines are getting better at answering our questions. And chatbots are increasingly likely to search the internet for relevant sources. ‘Search engines and chatbots will become more closely entwined’, says Professor Suzan Verberne.

It is not possible for juvenile courts to properly assess whether it is necessary to place a child in care. This is evident from a fact sheet that has been prepared by legal scholars from Leiden University, commissioned by the Dutch House of Representatives and others.

The collection guides of archives and collections of Leiden University Libraries (UBL) have been made available via the portal Collection Guides. This has greatly improved the findability, visibility and ease of use of these collection finding aids.

Bacteria carry countless hidden treasures in their DNA: fragments that could hold the key to new medicines. But how do you pick out the most promising ones from millions of options? ‘Look at the switches that turn genes on and off,’ says molecular biologist Gilles van Wezel.

When a child is placed in care, the assumption is always that the child can return home again. But there are still many questions about how this process – the 'permanency plan' – is arranged. New research aims to provide insights.

In Europe, the Netherlands is in middle position when it comes to the placement of children in care. The consequences of such a placement in care are often disastrous, says Mariëlle Bruning.

Unemployed people often need not only a financial safety net but also a stimulus to look for work. PhD candidate Heike Vethaak researched the effects of incentives used by benefit agencies, such as compelling people to widen their job search.

On Friday 12 November Professor of Palliative Medicine Yvette van der Linden will give her inaugural lecture entitled: ‘Timeless’. How do we spend our time if illness cuts it short? According to Van der Linden much stands to be gained in the area of care during this last phase of life. Among other things,…

The legal protection of parents and children in cases involving placement in care must improve. That is the opinion of Mariëlle Bruning, Professor of Children and the Law.

Lecture

Nearly all documents from the 16th and 17th centuries were written by more than one person but attributed to only one author. Professor Nadine Akkerman wants to rectify this oversight in her research on scribes.

Every year in the Netherlands, thousands of children are placed in out-of-home care because their parents are unable to look after them properly or because the children are at risk.

Professor by Special Appointment Anouk Goemans has received the National Youth Care Award 2025 from the ‘Stichting Steunfonds Pro Juventute’. The cash prize of €30,000 will go towards her research on youth care and youth protection.

How many children are waiting for help from youth services in the Netherlands at any given time? And exactly how long do they have to wait?

The waiting lists in youth care are alarmingly long. This has been confirmed again by a study carried out by a Dutch foundation The Forgotten Child.

After many years of preparations, CERN has approved a groundbreaking new experiment: the Search for Hidden Particles (SHiP). Physicist Alexey Boyarsky was involved from the start. ‘We know there is physics that’s missing and we aim to find it.’

Roughly arrested and subjected to extreme isolation. Using his experience, expert Jason Bhugwandass spoke to 50 young people who have spent time on Zikos wards (‘very intense, short-term observation and stabilisation wards’). He concluded that they’re ‘mostly locked up’ and leave ‘even more traumatised’…

Just like scientific articles, patents cite scientific literature to support their findings. These references provide valuable information on how science is used to develop practical applications. However, extracting this information from patents is not that simple.

Bacteria whirl around in the mouths of most people, forming dental plaques and sometimes causing nasty gum infections. Treponema denticola might be a dangerous pathogen, but not much is known about this bacterium. It was up to Ariane Briegel and her research group to change that.

On Friday 22 March, the Effective Protection of Fundamental Rights research programme held a successful Annual Research Day (Toogdag) in Gravensteen building. This year’s theme was ‘The Concept of Justice in a War Era: The Cases of Gaza, South Sudan and Bosnia and Herzegovina’.

The project officially started in September 2020, but with the enrolment of PhD students Hanum Atikasari and Shajeela Shawkat the research team of the ERC project 'Globalizing Palliative Care? A Multi-sited Ethnographic Study of Practices, Policies and Discourses of Care at the End of Life' is compl…

With the addition of over 16,500 new catalogue records, the collection of Johannes Tiberius Bodel Nijenhuis (1797-1872) is now almost entirely searchable online. The private collection of the Leiden map collector laid the foundation for the special collection of maps and atlases of Leiden University.…

Roll-up solar panels, bendable phone displays, or better computer chips… The EU project STIBNITE investigated the next generation of semiconductors, made from organic materials based on carbon, nitrogen, and boron. The project has now concluded. During the Open Science Debate on 1 July, the group will…
