Executive Summary

I skipped the noisy headlines and picked four quiet moves that are real, current, and useful this week:

• Longevity clinics are growing: Fountain Life raised $18M Series B and plans a Houston center this year. I’ll show where they’re opening next and how employers/insurers might respond. TechCrunch

• Drug testing on working human organs: Revalia Bio raised $14.5M seed to run studies on perfused (kept-alive) donor organs, a faster path to human-relevant data. I’ll map early suppliers. BioSpace

• Smarter delivery for RNA medicines: SYNTRA (Helmholtz Munich) won the 2025 m4 Award to spin out AI-guided delivery “vehicles” for RNA drugs. I’ll outline the spin-out path and likely vendor winners. Helmholtz Munich

• Chips that talk with light, not wires: A fresh U.S. patent filing (Aug 2025) shows a low-loss optical interposer for co-packaged optics. I’ll map foundries and packagers most likely to get first orders. patents.justia.com
