Lichens enthusiast Sander van Zon was eager to use his knowledge for his internship. He wrote an excellent thesis on lichens’ biodiversity in the city, of which his first scientific publication will appear soon. With it, he is nominated for the Leiden Science Young Talent Award 2022.

A meeting place for singing parrots. That is one of the ambitions of Michelle Spierings’ new project. With her awarded NWO XS grant, she wants to test the parrots’ hearing ability. ‘I am curious to see how they can recognise and imitate changing melodies. And it would be amazing to test that with a…

Grondstoffen werden vroeger over duizenden kilometers afstand vervoerd. Waarvoor werden ze geruild en waarom sloten mensen in West-Azië zich aan bij deze handelsnetwerken?

Bacteria temporarily live without their cell wall if dangerous viruses are near. A remarkable feature, as the cell wall is a sturdy barrier against threats. Still, the discovery has a logical explanation ánd might be of a consequence for fighting pathogenic bacteria, according to Véronique Ongenae,…

Martijn Verkuilen is the winner of the Unilever Research Prize 2022. By transferring DNA from a plant into yeast, he made the first move to produce a new drug for type 2 diabetes. He collected his prize in Wageningen on 24 November.

How do young zebra finches learn to sing? A research team led by researcher Katharina Riebel has developed a ‘RoboFinch’ to study just that. She and colleagues in the 'Seeing voices' research consortium have spent the past four years designing the robotic bird. And with success: young zebra finches…

Why are mycobacteria such successful pathogens? And are there defence mechanisms in the body that help reduce an infection? To find out, Annemarie Meijer has been awarded the NWO Open Competition ENW-XL grant. She will not explore this quest alone. Five other leading Dutch research groups are participating…

Pigeons, zebra finches and parakeets. Carel ten Cate studied bird sounds. But not just that. Together with linguists from Leiden, he investigated parallels between birdsong and language. On 9 June, his farewell symposium was held to mark the end of his broad career. Well, the end? Carel ten Cate has…

Fungi germinating in the lungs of patients. Doesn’t sound too nice, does it? Luckily, humans can deal with this normally, and we are able to clear the infection before anything comes to harm. However, in people with health issues, Aspergillosis can cause a lot of damage, especially if the fungus becomes…

In a world where bacteria are increasingly resistant to antibiotics, Emma van Groesen set out to find a solution. This month she obtained her PhD, after four years of research into new variants of the antibiotic vancomycin. With success.

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…

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.’

A bacterium hiding from the immune system and picking up bits of DNA from its environment. The result: gaining new traits, such as better protection against antibiotics. Fortunately, we have not found such a damning scenario yet. However, PhD student Renée Kapteijn did find the first clues, which…

Dick Schoof kan ook wel de buurman van de Haagse faculteit worden genoemd. Vooral vanuit zijn rol bij de NCTV werkte hij veel samen met de Universiteit Leiden en hielp hij onderwijs en onderzoek vooruit, vertelt hoogleraar Terrorisme en Contraterrorisme Edwin Bakker. ‘Voor een kritische vriend was altijd…
