Great job Maja Peng and Ludmila Kerhartová presenting our work on 🐭 vocal recognition 🎶 at the “Ethology 2026” conference in Grünau 👏. We also listened to Rosemary and Peter Grant giving amazing talks 🐦‍⬛. What an inspiration!
📣 Congratulations to Anna Kruppa who just finished her MSc thesis 🥳 and presented her study on USVs and inbreeding status in wild house mice! 🎉
How do 🐭 respond to USVs 🎶? Brava Anna! 👏

Before… and during the Vetmed Uni Open Door Day!

So very rewarding teaching children about the ultrasonic songs of mice and seeing the kids’ (and their parents’ 😉) faces upon hearing them for the first time (which we made audible for human ears). Come and visit us next time to see how we are using AI to decode the complex acoustic signals of mice. Thanks to Maja Peng and Bettina Wernisch for their great teamwork!

📣 Paper alert! Have you ever wondered what a ketogenic diet might do to unborn offspring? Here we show that pregnant healthy 🐭 on a ketogenic diet give birth to less females pups and that the male pups die earlier than controls.

🎉 Congratulations to Berta Retana Ferrés, who just defended her BS thesis at the University of Barcelona 🥳 presenting her work from the Erasmus internship that she did in our lab in Vienna! 😃 Berta found very interesting results on how 🐭 respond to USVs 🎶 👏
Thank you #LorentzCenter for funding us!
📢 Six papers 🐭, one wedding and one baby later 👶… congratulations to Dr. Doris Nicolakis 🥳, who just gave a great talk 👏 and defended her PhD entitled “Adaptive functions of courtship signals in male house mice (Mus musculus musculus)” 🎵 🎉 Looking forward to new great discoveries with Doris!
When you arrive at work and it looks like this! 😃

📢 Teresa Klaus heroically classified >53000 USVs in wild🐭during courtship and mating. We found changes in their vocal composition, some USVs correlated with mating success, and there is evidence for vocal duetting! 🎶 @KLIVVWien @VetmeduniVienna🐭

🎉 What a great job Martina Zani! Her MS thesis talk on USV discrimination in wild 🐭 was excellent. Congratulations! 🥳 @KLIVVWien @VetmeduniVienna🐭
