PNAS crystalline

Abul Tarafder (University of Oxford) and colleagues published a paper in PNAS showing how the phage Pf4 forms a sheath made of liquid crystalline droplets around its host, Pseudomonas aeruginosa, which protects it from antibiotics and more. This study combines electron cryomicroscopy, cryotomography, and more to thoroughly assess these occlusive sheaths. Check out the impressive images and videos!
