Abstract: This study presents the compression response of additively manufactured novel soft porous structures with architected microstructure. Six porous additively manufactured architected periodic structures with two‐fold and four‐fold symmetry were considered. The effect of pore shape… read more here.

DOI: 10.1073/pnas.2119907119
Abstract: Significance The newly described type IX secretion systems (T9SSs) translocate virulence factors and can mediate specialized gliding motility among bacterial pathogens of the Fibrobacteres–Chlorobi–Bacterioidetes superphylum. We visualized the spatial organization of the T9SS in its… read more here.
