This was Biology on Tap June! We had two fantastic speakers: National Geographic Explorer Mirte Bosse and Naturalis researcher Michaël Nikolaï sharing their research — from the still-unsolved mystery of Bornean elephants to iridescent dinosaur feathers.

Quizmaster: Kaan Sarıoğlu
Event’s host: Dr. Iva Njunjic

The whole idea behind Biology on Tap is simple: bring science out of universities and research institutes and into a relaxed space where people can meet scientists, ask questions, and get excited about research.

Very grateful to the National Geographic Society (National Geographic Society ) for supporting us this year and making it possible to host seven National Geographic Explorers at Biology on Tap.

More coming soon — next up in July: Becking and Isabelle Bult. We can’t wait! 🤩

Last night’s Biology on Tap pub quiz included an important scientific discovery:

City birds fear women more than men. 😅

We’re still processing this information.

Everyone knows what a dinosaur looks like. But is that image actually accurate? Did they have feathers or scales? And what color were they?

In this talk, we dive into the colorful world of dinosaurs. By examining fossilized feathers, we discover which pigments were present and what they can tell us about dinosaur coloration. But we go a step further, traveling back in time with the help of statistics and modern birds. Were bright colors, like those of a peacock, also possible in dinosaurs or was the past black and white?

Evolutionary biologist Michaël Nicolaï explains what we already knew and how two years of research on more than 5,500 bird species in the collections of natural history museums can teach us a surprising amount about the colors of dinosaurs.

Biology on Tap – Monday 8 June in Leidse Lente

We are very happy to welcome two great speakers:

🧬Mirte Bosse ( ) – National Geographic Explorer and researcher at Wageningen University

🦜Michael Nicolai, a researcher at Naturalis Biodiversity Center

As always, the talks will be in English, kept lighthearted and accessible for a general audience, and there will be plenty of opportunity to ask questions directly to the speakers.

And of course, the evening wouldn’t be complete without our well-known pub quiz – always a lot of fun and a great way to test your biology knowledge (or guess your way to victory).

📍 Location: Leidse Lente
🕢 Doors open: 19:30
🕗 Start: 20:00
🎟️ Entrance: Free

See you there!

Biology on Tap Leiden is excited to welcome National Geographic Explorer Mirte Bosse to the stage!

What can the DNA of endangered animals tell us about their past — and their future?

In this talk, Mirte Bosse takes us on a journey through the DNA of endangered animal species. Focusing on Asian elephants, she explores what the DNA of individuals in zoos can reveal about their wild counterparts.

This includes massive population crashes during the last Ice Age, as well as surprising exchange between related subspecies or genes that were important for local adaptation to new environments.

Finally, she explores how information from these genomes can contribute to better protection of populations currently under pressure in the wild.

Join us for an evening of science, storytelling, and conservation at Biology on Tap Leiden!

The talk will be in English and the entrance is, as always, FREE!

Thank you and for speaking at our event, we enjoyed learning about your research!

Our next event is taking place on 8th June. Stay tuned, speakers will be announced soon!

04/05/2026

Important! Our event starts at 8:30 pm this evening (30 min later than usual).

The ocean is absorbing an increasing amount of the CO₂ we release into the atmosphere. As it does, its chemistry is changing.

This “other CO₂ problem,” known as ocean acidification, can make it harder for marine organisms to build their calcium carbonate shells. One of those organisms is a mesmerizing, tiny planktonic snail: a shelled pteropod, also known as a “sea butterfly”.

They may be small, but they are essential in marine food webs and play a key role in the ocean’s carbon cycle. And yet, we still don’t fully understand how their fragile shells form- or how they respond to ocean acidification.

In this talk, will take you along on her scientific journey to explore exactly that: How pteropods build their shells across natural ocean gradients and in controlled experiments, and what this reveals about how they may respond to future ocean conditions.

We’re getting excited for the next Biology on Tap on May 4th – and you should be too 👀🍻

Two brilliant talks lined up: from tiny “sea butterflies” dealing with ocean acidification, to wild animals voluntarily hopping on running wheels (yes, really). Science, but fun – and slightly unexpected.

As always, it’s completely free, super informal, and a great way to spend your evening with curious people, good drinks, and fascinating stories from science.

Bring your friends, come grab a drink, and join us at 8:30 p.m. – we promise a fun night!
