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…

Tropical bananaquits lose song quality in the city
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…

How touchscreens and eye trackers can tell us something about the dating life of orangutans
Aesthetic attraction plays a big role in orangutans’ mate choice, behavioural biologist and PhD candidate Tom Roth has observed. But to discover just how big that role is, more research is needed into the emotions of the great apes.

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…

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…

Bacteria without cell wall gobble up DNA from environment
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…

How cells talk by pulling on a fibre network
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…

New technology could prevent the mass cull of male chicks
A staggering 6.5 billion chicks are killed worldwide every year. These are generally male chicks that are of no economic value. In Ovo has developed technology that can quickly determine the sex of a chick, to ensure that only female chicks are hatched. The first 150,000 chicks have now hatched in this…

New eDNA method opens doors for environmental research
With a single sample of water or soil, researches can analyse the DNA of everything that is living in that environment. During her research, PhD candidate Beilun Zhao discovered a way to analyse not only the kind of species, but also the age of the species in a water sample. The method showed its first…
