✳️uncovers a distinct cancer cell state with survival advantages in the pediatric cancer *Ewing Sarcoma*
✳️implicates membrane invaginations called *caveolae* that drive survival through subcellular organization of signaling molecules on the cell surface.

I'll remember the infectious enthusiasm and burning curiosity he brought to every conversation I had with him.

Our field has lost an amazing scientist, mentor, and old friend. Benny, along with Mike Hoffman, had a brilliant idea in the early 1980s. The first oncogenes were being cloned and they realized if we wanted to understand their roles in cancer, we needed to understand their normal function 1/n 🧪
