How do animals choose their partners? The answer is simple: it’s all about quality. While humans tend to wear clothes that happen to be in fashion, animals do nothing without a reason. Behind beautiful plumage or a deafening roar is only one message: I am in great shape. The evolutionary courtship displays…

More and more people are experiencing work pressure due to digital means of communication. Media like e-mail and Signal (WhatsApp) ensure that we can be reached day and night, which can cause an increased sense of work pressure and always being 'on call'. In February 2023, the new digital communication…

Information security is essential for Leiden University. This means not only that we deal with (sensitive) information in a secure and conscious manner, but also that incidents are reported as soon as possible. You can read below how to report incidents.

The Development and Alumni Relations department offers a number of offline and online communication resources for alumni. Alumni are approached via the Leidraad magazine, the digital newsletter Alumni News and the alumni website. The University also manages a number of social media accounts especially…

The new University Sports and Exam Centre is another step closer. Bigger sports and exam halls, plenty of room for meeting people, an open feel that integrates with the Campus Square and the sports fields, optimal acoustics and an uncompromisingly sustainable building with a green facade and solar panels.…

Hans Slabbekoorn researches animal sounds and the effect of the noise we humans make on these animals. He is also committed to making his discipline more diverse.

Hans Slabbekoorn is specialised in animal sounds. On 1 July, he was appointed professor of Acoustic ecology and behaviour. A great honour, according to the new professor. ‘This job never gets boring, whether I am investigating the urban jungle or marine noise.’

Work pressure is still high across the entire organisation. Leiden University is not unique in this respect, as all Dutch universities are facing high levels of work pressure. In an effort to reduce work pressure, we have launched a toolkit including practical measures at central, faculty, and individual…

To facilitate the search for new antibiotics. That is the aim of Gilles van Wezel, professor molecular biotechnology at the Institute of Biology Leiden (IBL). He wants to do this by looking at similarities in the DNA of antibiotic-producing bacteria. Van Wezel has been awarded an ERC Advanced grant…

Mechanics play a larger role in blood vessel formation, and other developmental biology, than previously thought. Cells appear to respond to mechanical signals, such as pressure. Through the extracellular matrix, a network of fibrous proteins, cells can supposedly exchange those mechanical signals over…

Last month, research by the National Institute for Public Health and the Environment (RIVM) revealed that more than half of students in higher professional education and at universities experience psychological complaints and emotional exhaustion, and that a quarter of them suffer from anhedonia (loss…

The new Neurodiversity Platform supports staff who need better working conditions because they have ADHD or autism, for instance. Stefan de Jong, who is organising the Platform’s first online meeting on 15 November, tells us about the initiative. Register now if you’re interested.

Biophysicist Alireza Mashaghi and his collaborators are taking up the fight against muscular dystrophy: genetic disorders that cause muscle weakness. They want to inhibit the clumping of proteins that results in toxic aggregates. For this, the team receives 550,000 euros from Health Holland. The team…

Underwater noise from seismic surveys affects the behaviour of Atlantic cod. These are the results of research by Leiden biologists in collaboration with colleagues from Belgium. During such surveys the fish are less active than usual and their circadian rhythm is disrupted; soon after exposure they…

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…

What skills do students need to function as academic professionals and engaged citizens?

On the brand-new Leiden Teachers Blog, Leiden teachers share their experiences with educational innovation. They show colleagues, students, and everyone else who is interested the different facets of creating university education.

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

I think we should go this way. This way! THIS! WAY!! Making yourself heard in a city can be difficult. That is not only the case for humans, but birds seem to be hindered by urban noise as well. Researcher Hans Slabbekoorn of Leiden University already showed that great tits in Leiden communicate differently…

Computer scientist Tim Coopmans uses pen, paper and regular computers to simulate the best possible quantum computer. He tells about his research and how this helps make a useful quantum computer a reality a little bit sooner. ‘I hope I will get to see quantum computers contributing something really…

A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…

From painful joints to intense fatigue: a third of rheumatism patients suffer serious effects from this chronic condition and rely long-term on medication. Leiden psychologists are to receive a subsidy from the Netherlands Arthritis Foundation to investigate whether placebo techniques can help patients…

Whether finding signals of dark matter or discovering hydrogen in the vicinity of exoplanets, Leiden astronomers are world players in their field, and they are part of a long tradition: Leiden was the first university in the world to have its own observatory.

‘Space Antenna LISA will open an unprecedented window on the Universe,’ says astronomer Elena Maria Rossi. The mission will be the first one to detect Gravitational Waves from space. These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

How are you doing in these strange and unprecedented times? This is the question we are asking our colleagues in this series of articles. This time we asked Erick van Zuylen, the University beadle.
