Some bacteria, it turns out, have proteins much like ours that organise the DNA in their cells. They just do it a bit differently. This is revealed by new research from biochemists at the Leiden Institute of Chemistry and the Max Planck Institute for Biology. The discovery helps us better understand…

Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

Astronomers have captured a new deep field of Pandora's Cluster (Abell 2744) with the James Webb Space Telescope. The images show never-before-seen details. The results are described in four scientific papers. Leiden astronomers Marijn Franx and Mariska Kriek collaborated on the study. 'This opens a…

Leiden scientists lead COLIBRE, a groundbreaking set of cosmological simulations. By including key missing physics, cold gas and cosmic dust, they offer the most realistic picture yet of how galaxies formed and evolved since the dawn of time.

For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…

Microorganisms that temporarily ‘go to sleep’ play an important role in the evolution and survival of a population. Mathematician Shubhamoy Nandan conducted research on the effect of this characteristic called ‘dormancy’ in a novel mathematical model.

No less than four Leiden research teams have been awarded a grant by NWO. On 27 July NWO honoured 21 applications in the Open Competition ENW-XL. NWO awards the grants to consortia in the exact and natural sciences who are doing unconnected fundamental research that is 'driven by curiosity'.

Three fundamental research projects at Leiden in physics, chemistry and medical science have received funding from the Dutch Research Council (NWO). They involve research on magnetic fields in the universe, the role of myeloid cells in cancer immunotherapy and the evolution of ancient proteins.

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of…

Are magnetic fields older than the first light? And how did they influence the development of our universe right after the Big Bang? Cosmologists from Leiden, Groningen, and Utrecht are now collaborating to investigate this.

Did he dare take a gamble with his PhD research? Jeroen Methorst didn’t have to think long about it. It could fail or turn out very well. The latter is the case. Methorst developed a computer system that helps researchers find the protein they need. ‘Our whole group is now using this program.’ Methorst…

Exploring the largest structures in the universe by looking at the tiniest particles? Lydia Stofanova, PhD candidate at Leiden Observatory and SRON Netherlands Institute for Space Research, dives into this intricate connection. In her PhD research, she explored how elements like oxygen influence the…

For the following years, Dr Aitor Burguet-Coca will be a returning face at the Faculty of Archaeology. He will join Dr Amanda Henry’s team with his expertise on prehistoric fire use and the methodologies that studying ancient hearths requires.

An evolutionary 'trap' that has haunted crested and marbled newts for 25 million years: Leiden researchers have uncovered a mysterious DNA error that should not be able to arise – yet persists all the same. How is that possible? PhD candidate James France found new clues.

Today, ESA’s Gaia mission releases its new treasure trove of data about our home galaxy. Astronomers, led by the Leiden astronomer Anthony Brown, describe strange ‘starquakes’, stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date.

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 opinions form and change in large groups of people? That's not just a sociological question, it's a mathematical one. PhD candidate Federico Capannoli studied opinion dynamics. He defended his thesis on November 19.

Hardly anyone in the Netherlands ever watches skeleton racing. But we’ll soon be glued to our TV sets when ‘our’ Kimberley Bos slides down the track at the Olympic Games. All because she stands a good chance of winning a medal. Why do we like winners so much?

Words originally intended to indicate space, such as ‘out’, are also regularly used to indicate cause and effect. Why does this happen? And how does it work in other languages? PhD candidate Camil Staps decided to find out.
