Siaẖ Biologim (The Biologists’ Colloquy), a one-day professional development seminar for high school biology teachers, took place yesterday for the tenth time (!) since its debut in 2010. Almost 100 teachers attended talks about cutting-edge biological research and clinical practice, delivered by four Technion faculty members, with topics ranging from localized translation in eukaryotic cells to antibiotic resistance and antiretroviral therapy. A recent Science paper about the structure and function of amyloid-like fibrils was presented as well. The seminar was organized by Aviv, and this was his third time organizing Siaẖ Biologim.
