An atomic model for the human septin hexamer by cryo-EM

Deborah C. Mendonça, Samuel L. Guimarães, Humberto D’Muniz Pereira, Andressa A. Pinto, Marcelo A. de Farias, Andre S. de Godoy, Ana P. U. Araujo, Marin van Heel, Rodrigo V. Portugal and Richard C. Garrat   Abstract In order to form functional filaments, human septins must assemble into hetero-oligomeric rod-like particles which polymerize end-to-end. The rules…

Emergent quasiparticles in Euclidean tilings

F. Crasto de Lima and A. Fazzio A material’s geometric structure is a fundamental part of its properties. The honeycomb geometry of graphene is responsible for its Dirac cone, while kagome and Lieb lattices host flat bands and pseudospin-1 Dirac dispersion. These features seem to be particular to a few 2D systems rather than a…
