TL;DR: A family of DNA tetrahedra, less than 10 nanometers on a side, that can self-assemble in seconds with near-quantitative yield of one diastereomer are reported that can be connected by programmable DNA linkers.

TL;DR: A linear elastic regime that can be described by both thin-shell theory and finite element methods is found, in which microtubules are modeled as hollow tubes, and a nonlinear regime and catastrophic collapse of the microtubule under large loads are found.

TL;DR: Analysis of the response of single 3T3 fibroblasts that were indented with a micrometer-sized bead attached to an AFM cantilever at forces from 30–600 pN found that at such small deformations, the elastic modulus of 100 Pa is largely determined by the presence of the actin cortex.

TL;DR: Evidence of a mechanism to reinforce the strength of an icosahedral virus by using its genomic DNA as a structural element and evidence of biologically relevant conformational rearrangements of the capsid around pores located at the fivefold symmetry axes suggest that the bound DNA may reinforce the overall stiffness of the viral particle without canceling the conformational changes needed for its infectivity.

TL;DR: It is proposed that F-actin turnover is the driving force in myelin wrapping by regulating repetitive cycles of leading edge protrusion and spreading.
