What does Leiden physicist Wolfgang Löffler think about the award of the Nobel Prize for physics to Arthur Ashkin, Gérard Mourou and Donna Strickland?

Leiden physicists and chemists have managed to bring two graphene layers so close together that an electric current spontaneously jumps across. In the future this could enable scientists to study the edges of graphene and use them for sequencing DNA with a precision beyond existing technologies. Publication…

A delegation from Leiden University is visiting Brazil from 14 to 18 March. The first day of the visit was spent with scientists in São Paolo.

After seven years, Eric Eliel resigns as scientific director of the Leiden Institute of Physics (LION). On April 18th, LION hosts a farewell party and a week later Eliel will officially hand over his tasks to Jan Aarts. We spoke with him about his term as director, in which among others a new science…

Physicist Sense Jan van der Molen researches materials that do not exist in nature. ‘It’s fascinating to see how the properties of a material change if we manage to make it super thin.’ He will give his inaugural lecture on 21 October.

Rogier Kegge, Assistant Professor at the Institute of Public Law of Leiden University, was interviewed by Dutch newspaper de Volkskrant in response to the recent recommendations by Johan Remkes on how to approach the nitrogen crisis.

The European Court of Human Rights recently ruled in favour of a group of older Swiss women. The issued concerned the health of senior citizens, especially women, who experienced symptoms as a result of climate change. They claimed that the Swiss Government should have taken more climate action, as…

On 20 and 22 November Rick Lawson, Professor of European Law at Leiden Law School, gave lectures at Cleveringa events in Bratislava and Budapest.

At the annual research day (‘toogdag’) of the research programme Effective Protection of Fundamental Rights in a Pluralist World (EPFR), researchers reflected on the growing threats scholars face due to political repression, conflict or displacement, and how to protect them.

Close contact between women and dogs in prehistoric times Women and dogs were in close contact in the neolithic age of hunters-fishers-gatherers. This has been suggested by Leiden osteoarchaeologist Dr Andrea Waters-Rist and fellow researchers who have studied a tiny biological fossil. The fossil was…
