On 15 January, the winner of the famed LION Image Award will be announced. Submissions ranged from the famous 3d printed microboat to an eerily abstract graph depicting a Majorana fermion.

The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…

With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

Martina Huber, Jacqueline Labra Munoz research Alzheimer's disease. They study ferritine, iron storage in the brain. An inbalance of iron could play a role in this form of dementia.

How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

Research into depression in children, Leiden alumni in the Dutch House of Representatives and an exceptional achievement by one of our students: what do this topics have in common? They are among our most read stories of 2021.

Elephant toothpaste, a trip among the stars or a lecture on mathematical juggling: on Sunday 8 October 2023, the Faculty of Science opened its doors for the third edition of the Leiden Science Family Day. A programme jam-packed with workshops, demonstrations, lectures and peeks behind the scenes for…

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

It's time for the 2021 Image Award

Working in a laboratory is different from working in an office. Some of the rules that apply when working in or around a laboratory are given below.

This Thursday, January 18th 2024, our esteemed colleague Jan Zaanen passed away. Jan was one of our star scientists, larger than life, with an unabashed, boisterous drive for the best of physics at the Institute Lorentz, at the Leiden Institute of Physics and in the full international scientific community.…

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…

Prof. Nele Mentens and her team are going to investigate how we can better secure our electronic and mobile devices connected to the Internet of Things. For this PROACT project she will receive no less than 1.8 million euros from NWO. They will use this money to develop chips that make the Internet…

What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

Confetti, stilt walkers and the new Einstein Fountain. On Monday, 2 September, the Gorlaeus Building of the Faculty of Science was festively opened. Together with Constantijn van Oranje, our students cut the ribbon. Dean Jasper Knoester: ‘The building is ready, now it is up to our students and researchers…

How can you persuade researchers who are used to conducting research within clearly defined disciplines to adopt an interdisciplinary approach? Newly appointed distinguished professor Arnold Tukker explained.

In less than a week’s time, millions of Turkish people are going to decide who will govern their country for the next five years. These elections promise to be the most closely contested in years, with the opinion polls showing very small differences and everything at stake, including for Europe. Alp…

Five projects with researchers from Leiden University have received a grant from the Dutch Research Council (NWO) to build or upgrade existing research facilities.

'With this artwork, I want to give the audience a glance into my overstimulated brain and that of other people with autism', says Jasmijn den Hoed. The Faculty of Social and Behavioural Sciences is exhibiting her artwork 'Overstimulated' in the restaurant near the blue wall during Autism Week 25 March…

Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal what is taking place under the surface.

Why are morpho butterflies blue? That is what high school students Frederique Kerstens and Koen van Griensven investigated in their high school profile paper at the Leiden Institute for Research in Physics. In doing so, they won the KHMW Profielwerkstukprijs 2023. ‘We didn't expect it, but are of course…
