To what extent do nanoparticles accumulate in plants and animals, and what properties of the particles play a part in this? Willie Peijnenburg, professor of Environmental toxicology and biodiversity was awarded a Marie Curie grant to conduct research on the environmental effects of nanoparticles.

The world is becoming clogged with plastic, with tiny plastic particles found everywhere, from the oceans’ depths to the mountain tops, soil, plants, animals and even inside us. The question is: what harm, if any, are they causing? In a new article on The Conversation, environmental scientists Meiru…

'We have to look for products that can replace ordinary disposable plastics, for example of organic material. Within 20 years, the average plastic use of a household will be largely reduced.' According to Thijs Bosker, Associate Professor at Leiden University College, in Edition NL of Tuesday, October…

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…

The Leiden University Medical Center (LUMC), the Danstem Institute from the University of Copenhagen and the Murdoch Children’s Research Institute in Melbourne have received 300m euros from the Novo Nordisk foundation. The aim of this new international consortium is to bring stem-cell based therapies…

A group of biology students are working on a solution to the world’s plastics problem by getting bacteria to make biodegradable plastic.

The number of lions in Kenya is decreasing alarmingly, due partly to the encroaching cities and the development of the countryside. Together with local scientists and inhabitants, Leiden biologists are studying how this decline can be halted. ‘Lions are cleverer than we thought.’

You can't see them with the naked eye, but they are highly likely to pose a threat to our health: microplastics. These tiny plastic particles are present everywhere in the environment, including within our bodies. On science platform The Conversation molecular biologist Meiru Wang offers valuable insights…

Scientists have discovered that starlings and parrots can imitate the complex sounds of Star Wars droid R2-D2 remarkably well. Their study reveals how the structure of a bird’s vocal organ determines its vocal abilities – and how citizen science helps uncover it.

Primate and test specialist Jane Goodall paid a visit to the Hortus botanicus in Leiden on 21 May for a ‘meet & greet’. Goodall, a world-famous researcher and nature protectionist, was presented with an orchid named after her and used the occasion to draw attention to the issue of plant protection.…

She narrowly defied bureaucracy and spent days angling for cod. In the North Sea, marine biologist Inge van der Knaap discovered that noise significantly disturbs fish behaviour. ‘There is now a lot of attention for underwater noise.’

The work done by SUMO proteins in the cells of our body is of vital importance. Molecular cell biologist Alfred Vertegaal has been studying these proteins for nine years, first with a Veni subsidy and then with a prestigious Vidi subsidy.

Proactive zebrafish appear to have a much stronger wake-sleep rhythm than reactive fish. In the most reactive fish, rhythmicity appears to be lacking completely. This is shown with research by Leiden biologists, published in December 2018 in the journal BMC Biology.

When the tokay gecko loses its tail, a new one grows from resident stem cells at the stump. Each tissue type - muscle, bone, blood vessels and skin - develops from specific stem cells. This discovery by Luthfi Nurhidayat holds potential implications for advancing regenerative medicine in humans. Nurhidayat…

Fleur Visser was awarded a Veni grant by the Netherlands Organisation for Scientific Research (NWO). She is one of seventeen promising young Leiden scientists, who get the opportunity to develop their own ideas over a period of three years. Veni-funding is part of NWO's Talent Scheme, concerning…

Wolves in the Netherlands mainly feed on wild animals such as wild boar and red and roe deer. But in areas such as Drenthe where these are scarce they also prey on free-roaming cattle used for nature conservation

Explaining your PhD research to others can be quite difficult, especially without talking! PhD student Annebelle Kok of the Institute of Biology Leiden was one of the finalists of the 'Dance Your PhD' competition of scientific journal Science. ‘You have to understand your own research well if you are…

On December 16, 2023, our respected and beloved former colleague prof.dr.ir. Bert Peletier passed away.

Nienke Beets of the Leiden Hortus botanicus has won the brand new Joke 't Hart Prize for connecting nature and art. For the botanical garden in Leiden, she developed a series of colourful plant icons and an educational board game. On 20 May, the Dutch Association of Botanical Gardens (NVBT) unanimously…

Public funding for fundamental research is essential for innovation and the development of new medicines. This is demonstrated by Professor Science Based Business Simcha Jong and his colleague Hsini Huang after studying US federal funding restrictions for stem cell research under President George W.…

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.

Brand-new professor Gerard van Westen works at the intersection of artificial intelligence and drug development. For the new chair in Artificial Intelligence and Medicinal Chemistry, he uses computer models to make drug development more efficient. Our ultimate goal is a virtual human which allows you…

Is our musicality unique? That’s what the Bird Singalong project aims to find out. And for that, they need the help of feathered friends from all around the world. ‘By researching how parrots learn songs, we also learn more about the origin of our own musicality.’ Do you have a parrot that can sing…

On the 1st of October a new project funded by the Joint Industry Programme (JIP) started at the IBL on the potentially negative effects of sound on fish. Behavioural biologist and bioacoustic specialist Dr. Hans Slabbekoorn leads the international research team.

While offshore wind farms generate clean and green energy, scientists are becoming increasingly aware of the harmful impact they may have on marine life. To get a better overview of these impacts and to find the best locations for future wind farms, environmental scientist Yali Si and her colleagues…

A team led by Erik Danen from the Leiden Academic Centre for Drug Research has received a 3 million euros NWO Science Groot grant to unravel the first steps of metastasis.
