One thousand plant transcriptomes and the phylogenomics of green plants (open access)

One thousand plant transcriptomes and the phylogenomics of green plants

Article describes the results of the One Thousand Plant Transcriptomes Initiative's efforts to sequence the vegetative transcriptomes of 1,124 species that span the diversity of plants in a broad sense (Archaeplastida), including green plants (Viridiplantae), glaucophytes (Glaucophyta) and red algae (Rhodophyta).

Evaluation of a Chicken 600K SNP genotyping array in non-model species of grouse (open access)

Evaluation of a Chicken 600K SNP genotyping array in non-model species of grouse

This article tested the cross-species application of the Affymetrix 600K Chicken SNP array in five species of North American prairie grouse (Centrocercus and Tympanuchus genera). Two individuals were genotyped per species for a total of ten samples and a high proportion (91%) of the total 580 961 SNPs were genotyped in at least one individual (73–76% SNPs genotyped per species).

Multimodal switching of a redox-active macrocycle (open access)

Multimodal switching of a redox-active macrocycle

This article looks at molecules that can exist in multiple states with the possibility of toggling between those states based on different stimuli. They have potential for use in molecular switching or sensing applications. The coupling of two different oxidation states with two different charge-transfer states within one macrocyclic scaffold delivers up to five different optical outputs. This molecular switching manifold exploits intramolecular coupling of multiple redox active substituents within a single molecule.

Electrostatic equilibria of non-neutral plasmas confined in a Penning trap with axially varying magnetic field (open access)

Electrostatic equilibria of non-neutral plasmas confined in a Penning trap with axially varying magnetic field

This article describes a procedure for computing the electrostatic equilibria of non-neutral plasmas in a Penning trap with a nonuniform magnetic field by solving Poisson's equation using an iterative method. Plasma equilibria in a model Penning trap with high and low field regions are computed. The plasma is assumed to follow the Boltzmann density distribution along magnetic field lines.

Artificially structured boundary plasma trap

This article presents a computer simulation of single-species non-neutral plasma confinement using an artificially structured boundary. The results support the prospect of developing plasma space-charge based confinement, with an unmagnetized plasma of one species of charged particles confined by an electric field produced by an edge-confined plasma of a second species of charged particles.

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution (open access)

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution

In this article, freshwater macroinvertebrate diversity associated with lakes and ponds along the altitudinal gradient of a Magellanic sub-Antarctic watershed are assessed. A monotonic decline in species richness was observed with increasing elevation, with simpler and more even community composition at higher altitude. This pattern differs from the mid-peak trend found in streams of the same watershed. Functional feeding group structure also diminished with increasing elevation.

Giant spin Hall effect in two-dimensional monochalcogenides (open access)

Giant spin Hall effect in two-dimensional monochalcogenides

This article, using calculations from first principles, reveals for the first time giant intrinsic spin Hall conductivities (SHC) in these materials. In particular, the article shows that the SHC resonances can be easily tuned by combination of strain and doping and, in some cases, strain can be used to induce semiconductor to metal transition that makes a giant spin Hall effect possible even in absence of doping.
