To prove this, the physicists and computer scientists used a quantum processor for single photons. Their…

The shock wave triggered by one of the five galaxies making up the iconic Stephan’s Quintet appears to be less disruptive than previously thought, with the shock likely being cushioned by dust particles in the surrounding gas. This is according to the analysis of the first scientific observations of…

With these words Naledi Pandor opened the symposium 'Science Diplomacy and International Development', which was held in her honour on 27 Februari…

Antoni van Leeuwenhoek, the father of microbiology, died 300 years ago. 2023 has therefore been designated the Antoni van Leeuwenhoek year. The new Unimaginable exhibition in Rijksmuseum Boerhaave is about the amazing world that Van Leeuwenhoek made visible. What was so special about the way he worked?…

‘There is no such thing as a timeless Japanese soul,’ says newly appointed Professor in Modern Japan Studies Katarzyna Cwiertka. The first month of her professorship turned out to be a crucial test: Japan was hit by a destructive earthquake and tsunami, and Cwiertka had to keep her head in the midst…

Nanoplastics can accumulate in developing hearts, according to a study by biologist Meiru Wang from Leiden University. Her research on chicken embryos sheds new light on how these tiny plastic particles pose a threat to our health.

There are still things we can learn from the Ancient Greeks. How they managed to make sure that innovations were accepted, for example. A group of classics scholars, led by Leiden, will be carrying out research on this question funded by the largest ever NWO subsidy.

When you think of physics, do you think only of complicated formulas? You’re not the only one. Therefore, every year, the Leiden Insitute of Physics organises the LION Image Award to show another side of physics: beautiful images about intriguing science. The winner of the 2022 photo competition captured…

In order to build wind turbines and electric cars, we need tons of magnets. Currently, we import these mainly from China, which means Europe is very dependent on this superpower for the energy transition. This has to change, according to industrial ecologist René Kleijn. In the REEsilience project,…

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…

Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

The Gouy-Chapman theory describes what happens near an electrode when it is in contact with a salt solution, but this description does not match reality. Researcher Kasinath Ojha, assistant professor Katharina Doblhoff-Dier and professor Marc Koper present a new version. ‘The next generation of textbooks…

As the year draws to a close, many music lovers are looking forward to the Top 2000. How high is their favourite song and who is number one? But the list is often very predictable and the same songs are always in the top 10. According to neuropsychologist and associate professor Rebecca Schaefer, it’s…

Deep observations made with the MUSE spectrograph on ESO’s Very Large Telescope have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The exquisite sensitivity of MUSE allowed for direct observations of dim clouds of hydrogen glowing with Lyman-alpha emission in the…

In donut-shaped buildings, particle accelerators take super-detailed X-ray images. Yet those images are not good enough to learn how to drive on hydrogen for example. Mathematics PhD student Allard Hendriksen has developed an algorithm that improves the images without having to learn from data from…
