These microscopic harpoons are intensely irritating and potentially dangerous if they end up in your eyes, mouth or throat. His early observations detailing the existence of single cell organisms or “animalcules” as referred to at the time was met with much scepticism by the scientific community.

The kingdom of protozoa remains incompletely understood with only a few species being explored in depth due to either their roles as human pathogens or as model organisms for research. Discover (and save!) This invited me to view this water with great attention, especially those little animals appearing to me ten thousand times less than those represented by Mons. LAB Jumpstart is a 14-week after school program that serves under-resourced and minoritized high school students by promoting inquiry-based scientific exploration and facilitating the development of core laboratory and research skills.

Register here: https://t.co/oL8IelJ6Eh, RU ready for our virtual rendition of Talking Science? As part of this blog, I would like to introduce aspects of protozoa biology which I find remarkable by discussing three species who under selective pressure have adapted to meet their diverse lifestyles. After successfully completing the program—alongside 15 other like-minded youth and a support team of scientists—students will embark on our 7-week, virtual Summer Science Research Program (SSRP), where they will get to apply their learned skills to specific research tracks.

Reasons for this scepticism include an inability to reproduce Leeuwenhoek’s work for several years and a general disregard for Leeuwenhoek’s findings because of his writing skills. The protist Euglena gracilis has recently been demonstrated by Riedel-Kruse and colleagues to be a useful model organism for interactive biology; the practice by which a user regardless of expertise can interact with a microorganism through a combination of touch and sight.
