Calling on universities and funders: make research information open
Crucial information about research, funding or how university rankings are created is often not freely accessible. The Barcelona Declaration on Open Research Information calls for such information to be made open. Professor Ludo Waltman is one of its initiators. What needs to change?

Astronomers see birth cluster of galaxies in early universe
An international team of astronomers has discovered a large reservoir of hot gas in the cluster-in-formation around the Spiderweb Galaxy. Based partly on that hot gas, the astronomers predict that the cluster-in-formation will grow into one of the largest objects in the universe. A step closer to discovering…

Leiden researchers join forces against tuberculosis
About one and a half million people worldwide die each year from tuberculosis. For thirty years, therapy with antibiotics has been the same, while it takes far too long and can lead to resistant pathogens. Leiden researchers from four institutes are now joining forces to develop more effective and efficient…

Antibiotic resistance: an economic problem universities could help to solve
Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.

What do complex molecules tell us about star formation?
How do you progress from an immense gas cloud somewhere in the universe to a star with planets? Research by Astronomy PhD student Martijn van Gelder sheds more light on the earliest phases of this process. He will receive his doctorate on November 24th.

Applications that never crash again
Doing your taxes, Netflixing or driving a car: more and more daily activities are supported by computer applications. It is challenging and expensive to test software thoroughly, leading to errors in most applications. PhD candidate Benjamin Lion made a mathematical framework to deal with this problem.…

Planet found too big for its parent star
The discovery of a planet far too large for its sun defies models about the formation of solar systems and planets. In a paper in Science, researchers, including Yamila Miguel of Leiden Observatory, report the discovery of a planet more than 13 times heavier than Earth orbiting the ultracool dwarf star…

Researchers tackle antibiotic-resistant bacteria
When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…

Honours Class on inequality: 'Focus on the big issues’
At the end of December, the concluding lecture of the Bachelor Honours Class 'Policy and Politics: struggling to combat social inequalities' took place. Students, under the guidance of former minister Jet Bussemaker, tackled the question of what inequality actually is. "You can't avoid it when you look…

Unique ‘penis plant’ flowers at Hortus
Amorphophallus decus-silvae, or the ‘penis plant’ as it is known, has just flowered at the Hortus botanicus. It flowered for two days, and then the pollen, which the male flowers produced was collected. As far as the plant experts at the Hortus can tell, this was just the third time that this species…

How light and noise pollution disrupt aquatic life
Fish populations in lakes and rivers have declined in recent decades. This is probably due to light and noise pollution. The Horizon Europe grant enables ecologist Hans Slabbekoorn to investigate this and improve the situation for migrating fish. In order to do so, a seven-metre-long swimming tunnel…

Sjoert van Velzen receives Vidi grant to solve 'riddles from the universe'
Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

Computing with rubber
Without electronics carrying out computational tasks our daily lives would look very different. Devices such as elevators, vending machines, turnstiles, washing machines and even traffic lights use a simple form of electronic computing to switch from state to state. But, what if power supply is not…

18 billion animals a year: they die, but never end up on our plate
Each year a staggering 18 billion chickens, turkeys, pigs, sheep, goats, and cows either die or are killed without making it onto someone's plate. Environmental scientists Juliane Klaura, Laura Scherer, and Gerard Breeman were the first to calculate this number on a global scale. 'Reducing these numbers…

'I always consider: What would have worked best for me?'
Starting with the ‘why’, putting herself in her students’ shoes and providing structure. These are three ways in which environmental scientist Ranran Wang tries to make her course as interesting and manageable as possible. With success: she has been nominated for Science Teacher of the Year 2022.

Algorithms descend into our sewers to improve inspections
They never cross our minds until, that is, they become damaged and then they’re a huge problem: our sewers. Their maintenance could be much faster and more accurate, PhD candidate Dirk Meijer has discovered. Algorithms are also proving to be a godsend deep underground.

Animation: Why Leiden is the birthplace of the Janssen vaccine
If you'll soon be getting a COVID-19 vaccine, you might just get the Johnson & Johnson (Janssen) one. This vaccine was developed for the most part in Leiden – and this is no coincidence. Watch the animation below about the development of one of the vaccines in the fight against COVID-19.

With this algorithm, new medicines can be found more quickly
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…

With 30 million dollars, this consortium aims to tackle tuberculosis
Thanks to a clever research method, progress is being made in the quest for better tuberculosis medications. Within an American consortium that received a 30 million dollars grant, Leiden researcher Rob van Wijk plays a significant role. ‘The next breakthrough in tuberculosis research will come much…

Improving nature’s antibiotic
'What nature made isn’t necessarily an optimized medicine to use in the human body,’ says Professor of Biological Chemistry Nathaniel Martin. That’s why a group of Leiden researchers is making a chemistry-based improved version of the frequently used antibiotic vancomycin. They received an NWO NACTAR…

Gaia data maps globular cluster, gravitational lensing and asteroids with great precision
The European Space Agency (ESA) has published an interim data release from Gaia, the space telescope mapping out the Milky Way in 3D. The first scientific papers published today reveal half a million stars in the Omega Centauri globular cluster, nearly 400 candidate gravitational lensers and the positions…

Motion of stars near Milky Way's central black hole is only predictable for few hundred years
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…
