Debates about the ‘end’ of the Roman era, how, when, and even if it ended, are still very much alive and raging. However, what happened after the (long) late antique period is a lesser-known and lesser-studied subject. The post-Roman past needs, however, as much energetic investigation and discussion.…

A single tiny molecule that can destroy flu, corona, HIV and Zika viruses? Yes, it really does exist. Biophysicist Niek van Hilten, who will receive his doctorate on 14 September, contributed to this discovery.

How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

An atomic vandal has finally been caught! Scientists from Leiden University and the Department of Energy’s SLAC National Laboratory have uncovered the mysterious cause behind the rapid corrosion of platinum electrodes. This breakthrough paves the way for more affordable green hydrogen production and…

An international team led by astronomers at Leiden University has shown in laboratory experiments that sulfur can bind with ammonium under icy cosmic conditions and form a salt that sticks to dust and pebbles. The resulting sulfur salt not only helps to explain the mystery of the missing sulfur gas,…

An international team of astronomers, led by Will Rocha of Leiden Observatory, using the NASA/ESA/CSA James Webb Space Telescope have discovered that the key ingredients for making potentially habitable worlds are present in early-stage protostars, where planets have not yet formed.

One and a half hectares of polder, a large volume of water, and a group of curious researchers from various universities and scientific backgrounds led by ecologist Maarten Schrama. These are the ingredients needed to answer the question: how do water retention areas affect nature, animals, and our…

The dark matter of biology: clumps of sugar molecules that, for example, form sugary webs around pathogens. We know very little about them. Wouter Remmerswaal threw all his talent into the challenge – both in the lab and as a modeller – and succeeded. He received his PhD on 12th September.

The placebo effect was completely new to her when Lingling Weng began the PhD project in Leiden. She is now a postdoc in China. 'It would be great to investigate the underlying mechanisms of placebo and nocebo effects with my current knowledge of EEG and fMRI.' PhD defence on 17 October.

Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…
