(1/n) DNA-PAINT imaging inside the nucleus at single antibody resolution using TIRF? Ultrathin sectioning makes it happen!
Grateful to share my postdoctoral work introducing “tomographic & kinetically-enhanced DNA-PAINT” or in brief: tkPAINT. Out in @pnas.org!

Hyperparasitisme : un virus qui parasite un virus qui infecte une amibe
Les virus aussi peuvent être infectés ! Un virus géant infectant une amibe est lui-même attaqué par un virophage, à son tour influencé par un élément génétique mobile, un transpoviron. Une cascade d’interactions étonnante révélée par des chercheurs marseillais.

“One of the challenges in science journalism is the oversimplification of research findings to attract attention. Headlines such as “scientists find cure for cancer” or “ozone layer is healing” are designed to attract readers’ attention but often misrepresent the complexity of scientific research.”

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.
