Nature research paper: A DNA origami rotary ratchet motor
Exemplary single motor particle trajectory, AC field first off, then on . Left, raw video of an exemplary single particle. Yellow cross indicates tracked position of rotor arm tip. The particle effectively rotates in CW direction when switching the AC field on. Right, cumulative angular displacement of rotor tip. The original video was acquired with 250 frames per second. Total frames collected: 10,082; video time: 40.328 s. Every second frame of original image stack was exported.
Exemplary single motor particle trajectory seen during AC voltage sweep . Left, raw video of an exemplary single particle. Yellow cross indicates tracked position of rotor arm tip. The AC voltage was increased stepwise from 0 V to 60 V and then shut off again. Right, cumulative angular displacement. The original video was acquired with 250 frames per second. Total frames collected: 12,000; video time: 48 s. Every second frame of original image stack was exported.

Dispersal and fire limit Arctic shrub expansion - Nature CommunicationsShrub encroachment trends are widespread yet complex. Here the authors demonstrate that not considering dispersal and fire leads to overestimating shrub expansion in Arctic tundra and therefore its role as carbon sink.

Replicated radiation of a plant clade along a cloud forest archipelago - Nature Ecology & EvolutionSeveral cases of replicated radiations (in which sets of similar forms evolve repeatedly within different regions) have been described in animals. Here the authors provide a well-documented example in plants, specifically the Oreinotinus lineage within the angiosperm clade Viburnum in its spread from Mexico to Argentina through disjunct cloud forest environments.

Diverse metallicities of Fermi bubble clouds indicate dual origins in the disk and halo - Nature AstronomyA metallicity survey of Fermi bubble clouds reveals a wide range of metallicities, challenging the theory that all of these clouds launch from the Milky Way’s disk and instead suggesting that they originate in both the disk and halo.
