Ten years ago Tami, Roy, and I released a movie we made of antibiotic resistance evolving in real time. I thought maybe a couple thousand people tops would see it. I couldn't have imagined it would be seen millions of times, and be taught from middle school through the graduate level worldwide

Did you know that the cells of old animals contain much less mRNA than the cells of young ones? Let me share with you some results from an ongoing project in the lab, where we are finding that a progressive depletion of total mRNA abundance is a crucial part of aging 1/22

How do developmental pathways adjust when harsh environments cause delays or interruptions in development? 🧪🧬 C. elegans can enter the stress-resistant and developmentally arrested dauer diapause stage. Progenitor cells actively maintain multipotency during dauer. 🧵

Fun read! Another classic example is Cynthia Kenyon's discovery that loss of the insulin receptor DAF-2 extends lifespan in C. elegans, which came out of the control for a clever mutant screen in which progeny of single F2s are sent into dauer with daf-2(ts) to track lifespan of the parent.
