Using real-time deformability cytometry, researchers at the Max-Planck-Zentrum für Physik und Medizin in Erlangen were able to show for the first time: COVID-19 significantly changes the size and stiffness of red and white blood cells—sometimes over months.

This week we —  Natasha  and  Danny  and  Alex  and  Grace — had more than a little to noodle over, but not so much that we blocked out a second episode. We try to stick to our current format, but, may do more shows in the future. Have a thought about that? equitypod@techcrunch.com is your friend and we are listening. Now!
