End of the Second messenger course in the IBBM La Plata.
Excelent students, lectures, laboratory sessions and more. Hope this will be a life changing experience for everybody involved.

Phage therapy offers a powerful tool against AMR infections—but only if we move from isolated cases to coordinated systems. The first initiative of the ASM Health Unit, led by Colleen Kraft and Dev Mittar, will tackle this. Delighted by this scientific leadership, join us!

COVID Revisionism Has Gone Too Far If the center and left succumb to the view that “nothing worked,” no one will remain to defend sensible public-health measures the next time a pandemic comes around.

Great analysis of Macedo and Lee's "In Covid's Wake," revealing it to be cherry-picked storytelling that is often disconnected from evidence. Their institutional affiliation doesn’t make any of their arguments more true 🎁

“Grant review by political appointees will further impede the work of the scientific community to provide solutions and fight public health threats. With strong and responsible oversight, we need to harness—not suppress—all perspectives and approaches in the effort to solve these problems.”

I will be recruiting new postdocs with start dates end 2025 - early 2026. If you'd like to work at the Pasteur Institute in the heart of Paris surrounded by amazing scientists, reach out to discuss possible projects on SynBio / Bacterial Immunity!
