My article "Efficient cloning of linear DNA inserts (ECOLI) into plasmids using site-directed mutagenesis" was published in Scientific Reports in September 2024. Six months later, it is among the Top 100 most downloaded Cell and Molecular Biology papers, with 2,647 downloads.
Our PhD student Šárka is now giving a chalk-talk presentation on her Prickle and neurulation work in front of her fellow students — and she is doing great! Go, Šárka! 🐸💪

How do you make a group of scientists really busy?
Organize a scientific speed-dating session! Three minutes per pair — the clock is brutal.
Happy to host this one! 🔬⏱️😄

It’s fantastic to meet Oded Rechavi at my home institution! 🔥 Great chat about his work on the Dead Sea Scrolls, where his team used DNA analysis to reveal that some fragments came from different animals and regions — rewriting what we thought we knew about the oldest Bible. 📜🧬

🇲🇽 Hola, buenos días from México! The VI Neurobiological Conference has just kicked off.
Excited to step out of my comfort zone and represent not only our lab at Masaryk University, not only Brno, not only Czechia… but maybe even Europe! 🌍
Greetings from the heart of wild & central Mexico!🧠

Today I start the first lecture of my course Developmental defects (Bi1152en) at Masaryk University 🎓
My favorite part: to show how scientists in Mexico 🇲🇽 in 18–19th century were sometimes ahead of European colleagues, who were the “flagship” of science at that time. @jbwallingford.bsky.social
