Researchers at Leiden University Medical Centre (LUMC) have discovered precisely how this protein works by making MutS visible with cryo-electron microscopy.…

As a result of the refugee crisis and the terrorist attacks in Paris and Brussels, the Royal Netherlands Marechaussee (RNM) is stepping up immigration controls in the Dutch borderlands. These measures are part of the so-called Mobile Security Monitor (in Dutch: Mobiel Toezicht Veiligheid), “Schengen…

On Friday 5 February 2021 the online conference of the Dutch Platform of Empirical Legal Studies (ELS) took place. This conference served as a platform to bring young, enthusiastic and driven ELS scholars together in a research community and enable them to learn more and discuss about empirical research…

Professor Peter Bisschop has been awarded an ERC Advanced Grant. He will invest the 2.5 million euros in his research into puranas: ancient texts, commonly written in Sanskrit, that are up to fifteen hundred years old.

Pim Overgaauw is at his best when he can support others. His new position as Institute Manager of the Mathematical Institute is therefore a perfect fit. ‘My main goal is to ensure that our mathematicians can focus on the maths.’

We have to do all we can to stop climate change. But: the Earth is more resilient than we thought. That is the surprising conclusion of an international team of ecologists and mathematicians, which included Leiden mathematician Arjen Doelman. The team discovered that ecosystems can still avoid tipping…

As a prelude to the Night of Discoveries, an Afternoon of Discoveries will be held in Leiden on 21 September for children from the age of eight. Researchers will tell exciting tales and the children will get to do experiments.

Astronomers at ASTRON and Leiden University have used the LOFAR radio telescope to discover a 'brown dwarf' – a faint object more massive than Jupiter, but significantly less massive than the Sun. The discovery of the object dubbed Elegast, opens up a new path that uses radio telescopes to discover…

Friday October 24th Honours students had to present their case studies on a topical issue related to Humanities. All Honours students made posters in pairs of two and had to defend their case in front of an audience at the Old Observatory. It was a tense experience, since they were being graded by…

Leiden physicists and international colleagues from Geneva and Barcelona have confirmed the mechanism that makes magic-angle graphene superconducting. This is a key step in elucidating high-temperature superconductivity, a decades-old mystery central to physics, which may lead to technological break…

You speak Japanese, know everything about medieval art or understand exactly what Hegel meant. And then you graduate. Many Humanities students find it hard to enter the labour market. A relevant part-time job can help. Therefore, the faculty has been working together with the employment agency Randstad…

For the first time researchers have succeeded in placing a layer of graphene on top of a stable fatty lipid monolayer. Surrounded by a protective shell of lipids, graphene could enter the body and function as a versatile sensor. The results are the first step towards such a shell, and have been published…

In the early 2000s, Jatropha Curcas was worldwide promoted as a promising solution to global concerns on climate change, fossil fuel depletion and rural poverty. The seeds of this plant were supposed to produce valuable oil which could be used as biofuel. Henky Widjaja, PhD candidate at the Institute…

Warning colours ensure that predators remember that certain prey are poisonous. But now it appears that the colours of poisonous Panamanian frogs are also influenced by fastidious females: partner choice can also lead to colour change in these frogs, as Leiden researcher Martine Maan has reported in…

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…

He was already taking lectures in Astronomy in Leiden when he was 12, and at 15 he started a degree programme in Information Technology. 'The first reaction…

Graphene has held a great promise for applications since it was first isolated in 2004. But we still don’t use it in our large-scale technology, because we have no way of producing graphene on an industrial scale. Leiden physicists have now visualized for the first time how atoms behave in between graphene…
