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…

Within the same species of butterfly many different wing patterns can occur. How is this possible? According to researchers Ben Wielstra and Emma Berdan, of the Institute of Biology Leiden (IBL), the answer lies within supergenes. A supergene is a part of a chromosome that contains many strongly linked…

To eat or get eaten. It describes the evolutionary race of snakes versus the mammals and birds that prey on these snakes. Muzaffar Ali Khan devoted his PhD to investigating the molecular mechanisms play of the evolutionary arms race, and has his promotion 16 February. What makes mammals and birds successful…

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their research on February 19 in PNAS.

We do it every day but barely give it a thought: chewing our food. But the ‘simple’ process of masticating food may have played a crucial role in the evolution of our jaws, facial muscles and teeth.

An international team of researchers led by Leiden archaeology professor Marie Soressi and Leipzig senior geneticist Matthias Meyer has recovered the DNA of a woman belonging to an Ancient North Eurasian population from a 20,000-year-old pendant. This is the first time DNA analysis has been used to…

Optimised antibiotic combinations can combat bacteria more effectively while also slowing the development of resistance. Scientists from five European countries are joining forces to identify such combinations and provide tools for others to do the same. The project is led by Professor Coen van Hasselt…

Synchronised heart rates and skin conductance tell us that people are attracted to each other. This explains why we feel a romantic ‘click’ with some people and not with others. This is the result of research by psychologist Eliska Prochazkova from the Leiden Institute for Brain and Recognition, which…

Individuals suffering from social anxiety disorder (SAD) consistently avoid eye contact. However, in a non-clinical population, gaze avoidance in socially anxious individuals depends on social situations, Jiemiao Chen saw in a series of experiments, for which she used wearable eye-trackers. On 25 April…

On 2 November, nine professors were simultaneously inaugurated as ‘Medical Delta Professor’ at Leiden University, LUMC, Delft University of Technology, Erasmus University and Erasmus MC. With an appointment at a minimum of two of these five academic institutions, they combine technology and healthcare…

Professor Meta Roestenberg has been awarded the Mercator Sapiens Stimulus 2025 by the Royal Holland Society of Sciences and Humanities (KHMW). The prize of EUR 1 million will allow Roestenberg and her team to further develop an innovative malaria vaccine.

Barbara Gravendeel has been appointed as the new scientific director of Hortus botanicus Leiden. Additionally, she has been named Professor of Plants and Society. Gravendeel succeeds Paul Keßler, who held the position for nineteen years. Currently, she works as a group leader at Naturalis Biodiversity…

While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…

A new study carried out by Leiden archaeologists Hadar Ahituv and Amanda Henry, together with international colleagues, reports the identification and analysis of 650 starch grains preserved on basalt percussive tools (anvils and hammerstones) found at an early Middle Pleistocene site in Israel. These…

Seven Leiden professors have been elected as members of the Royal Netherlands Academy of Arts and Sciences (KNAW). In total 23 new members will be inaugurated on Monday 13 September.

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.

Electrical inner ear prostheses like Cochlear Implants (CIs) help deaf and severely hearing-impaired persons to regain many of their communication abilities. The performance of CI in social environments is, however, not optimal. The new "Machine learning To Enhance teMPoral cOding foR cochleAr impLants“…

Leiden researchers, Professor Remko Offringa and co-applicants Salma Balazadeh and Frederic Lens received an NWO-XL grant (2.5 million euros). Together with researchers in Wageningen and Groningen, they will study the genetic and environmental drivers of woodiness. From plant to molecule, the groups…

How has evolution shaped our curiosity? And how does that curiosity ensure that we now have the technological ability to discover whether we are alone in the universe? This was all covered during the celebration of Leiden University’s 449th Dies Natalis.

On Sunday night 25 September, all the lights in Leiden will switch off and we will see the starry sky above us twinkling in all its glory. A unique opportunity for all residents of Leiden to experience the vastness of the cosmos and view the impressive artwork that hangs over our heads every night.…

Modern humans and Neanderthals may have co-existed in France and Northern Spain for up to 2,900 years until the Neanderthals disappeared. This is what archaeologists from Leiden University and Cambridge University write in a new publication in Scientific Reports.

Discover budding creators, artists and researchers at the Night of Discoveries art and knowledge festival. And many researchers from Leiden University are taking part.

‘I did not expect to receive the grant, but it will make an amazing research possible,’ Michelle Spierings says. The researcher of the Institute of Biology Leiden (IBL) got awarded a Veni-grant of the Dutch Research Council (NWO).

How unique is the human capacity for learning and adapting to an environment? In field research – in the rainforest and Artis Zoo – primatologist Karline Janmaat is studying how humans and other primates adapt to their environment in their search for food. She will give her inaugural lecture as Professor…

In the tropical rainforests of Southeast Asia the soursop family (Annonaceae) can be found. The genus Uvaria is a part of this family, but it has not yet been described entirely correctly. That is what Annas Rabbani will be studying during the next four years as a PhD student at the Hortus botanicus…

That a parrot can copycat sounds is nothing new. But vocal learning is not common in animals. Researcher Carel ten Cate of the Institute of Biology Leiden (IBL) of Leiden University has now discovered a duck species that can imitate sounds. ‘It started with an obscure reference about an Australian musk…

Adults who were abused or mistreated as a child and consequently suffer from post-traumatic stress disorder (PTSD) can benefit greatly from cognitive behavioural therapy. This is the conclusion of a study of 149 patients. Researcher and PhD candidate Chris Hoeboer is hopeful about the results and the…

If you buy something online, the webshop can adjust the price based on your data. Kimia Heidary investigated the phenomenon of online price discrimination. ‘It’s not necessarily unfair. Different prices for different people has been around for years.’
