Sections through the three-dimensional reconstruction volume (upper left, grey) around a pulmonary alveolus with hyaline membrane (lower left, yellow). In the centre is the air bubble (alveolus). The electron density is represented by different shades of grey. On the inside of the air bubble is a layer of proteins and dead cell residues, the so-called hyaline membrane. This deposit, which can be represented in its three-dimensional structure for the first time by the new method, reduces the gas exchange and leads to respiratory distress.

Using a special X-ray microscopy technique, they were able to image changes caused by the coronavirus in the structure of alveoli (the tiny air sacs in the lung) and the vasculature.
