To the insect folks — does anyone have experience with the World Precision Instruments injectors? Our new Nanoject III stopped working after the third use, and we’re now exploring other options, such as this one

🦟 Can we "pasteurize" mosquitoes to stop dengue & Zika?
Sarah Merkling @merklinglab.bsky.social uses AI + CRISPR to analyze stomach cells and understand why some mosquitoes spread viruses while others don't.
Goal: Make disease-carrying mosquitoes harmless.

Sarah Merkling wants to "pasteurize" mosquitoes!
At the Institut Pasteur, Sarah Merkling's research focuses on a topic that is still largely unknown: interactions between mosquitoes and viruses. She boldly devises novel strategies based on state-of-...

Excited to announce the final version of the Mosquito Cell Atlas is out now in @cellpress.bsky.social!! 🦟🩸
There is SO much left to find & investigate in this dataset (& the rich biology of the Aedes aegypti mosquito)! We hope this helps scientists in many fields!

Our new study is out in Cell Reports!
We show that the DNA repair pathway ATM-γH2Av is repurposed in the gut during infection, even without DNA breaks. Pathogens, not microbiota, trigger it via NOX to clear damaged cells and drive stem cell regeneration. www.cell.com/cell-reports...

Infectious bacteria, but not the microbiota, induce a NOX-ATM-cytokine pathway that controls epithelial turnover
Nagy et al. identify a NOX-ATM-cytokine signaling axis in the Drosophila gut that
is activated by infection independently of DNA damage. This pathway promotes enterocyte
loss, cytokine production, and...
