Lab-grown mini-lungs could reveal why covid-19 kills

What happens next could shed light on the strange and deadly effects of covid-19—because it’s not just the virus that matters, but the body’s reaction to it. People are dying from that reaction, and organoids could help zero in on where the damage is worst. Accurate cell models are already pinpointing how the virus gets into the body, where it causes the most harm, and will help in the search for treatments. MIT Technology Review
