Excited to share our new study published @pnas.org! We found that Shiga toxin-induced human cell death, long believed to be apoptosis, is in fact pyroptosis mediated by NLRP1 & gasdermin E. Congrats to all the authors! @uconnhealth.bsky.social @uconnresearch.bsky.social www.pnas.org/doi/10.1073/...

My colleague @sarahhird.bsky.social has been fighting for family care leave for over a year now. So impressed with her leadership! ctmirror.org/2025/10/21/t...
ctmirror.org
Opinion: This is UConn: Zero paid family leave for professors
UConn currently lets every pregnant/expecting individual reinvent the wheel, cobbling together a leave plan with whatever resources and departmental grace they can muster.

I was that woman! I have frequently told the story of how Jeremy responded after my second NIH rejection. He said, “Whatever you do, don’t stop spending. If you run out of startup, we’ll find more money for you.” I didn’t need it in the end, but knowing he had my back was huge. Thank you!

Macrophages recycle phagocytosed bacteria to fuel immunometabolic responses - Nature
Phagocytosed bacteria can serve as an alternative nutrient source for macrophages, influencing their metabolic and immune responses through the recycling of microbial components, with the process regulated by nutrient-sensing mechanisms and bacterial viability.
