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

Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

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.

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.

How do you write a report, how do you use an agenda during a meeting and how do you pitch your research proposal to an expert panel? As a student you have to write, collaborate and present. But how do you do that? The e-learning skills platform is there to help with the skills you need during your s…

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.

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.’

Conference

This academic year 49 promising international students will start their master’s degree here thanks to a Leiden University Excellence Scholarship (LExS). The students, all from outside the EU, were welcomed in a special ceremony on 5 September. Who are they?

Is it a coincidence that three chemists from the same department have each independently received a ZonMw grant? 'No,' the researchers agree in unison. 'The role of chemistry in medical biology is becoming increasingly important, and we’ve worked hard to make this happen.'

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…

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…

Herman Spaink knows of many substances that may help combat tuberculosis. Lab space to study them safely is very limited in Leiden. A brand-new lab at Universitas Gadjah Mada in Indonesia will soon provide a solution. About time, says Spaink, ‘The disease is on the rise and is becoming less sensitive…

Sander van Kasteren (Professor of Molecular Immunology) makes the invisible visible. He will explain more in his inaugural lecture.

Conference

For over a year now, the James Webb Telescope has been sending stunning images that exceed astronomers’ expectations. The photos are fascinating to see, but what exactly are we looking at? Assistant professor Melissa McClure explains.

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.

What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

How do you engage students? Sander van Kasteren knows how to do that like no other. ‘He compares immune cells to Pokémon and doesn’t just give information; he tells stories,’ students say about their favourite lecturer, Sander van Kasteren. The Professor of Molecular Immunology passionately teaches…

Leiden researchers, led by Sebastian Pomplun developed a new method to screen hundreds of thousands of molecules for drug discovery, using mass spectrometry instead of DNA tags. ‘We wanted to make drug discovery faster and more accessible.’

Smart drug carriers, uneven cosmic expansion, and solar energy storage in molecules. These are the topics of three newly awarded NWO-XS grants to researchers at the Faculty of Science.

Lecture, Tuesday Talks: Science Insights

With the search for new antibiotics becoming increasingly urgent, artificial intelligence offers valuable help. Smart software developed by Leiden PhD candidate Alexander Kloosterman searched genomes of bacteria and found clusters of DNA that code for proteins that have an antibiotic effect. ‘This new…

Researchers at the Universities of Amsterdam (Uva) and Leiden together with the Netherlands Cancer Institute and Oncode Institute have received a €10,6 million ERC Synergy Grant to develop innovative therapeutic approaches to target glioblastoma. This is a deadly primary brain tumour for which no curing…

What happens in the brains of people with psychiatric illnesses? With a €23.23 million gravity grant, scientists from different fields will search for biological causes over the next decade. ‘By joining forces, we hope to improve diagnosis and treatment for patients with these diseases.’
