Remodeling the epigenome and (epi)cytoskeleton: a new paradigm for co-regulation by methylation (open access)

Remodeling the epigenome and (epi)cytoskeleton: a new paradigm for co-regulation by methylation

This article is a commentary on coordinated use of methyl marks to remodel both the epigenome and the (epi)cytoskeleton, which opens the possibility for integrated regulation (referred to as ‘epiregulation’) of other higher-level functions, such as muscle contraction or learning and memory, and could even have evolutionary implications.

Evolution of microstructure and mechanical properties in gas tungsten arc welded dual-phase Fe50Mn30Co10Cr10 high entropy alloy (open access)

Evolution of microstructure and mechanical properties in gas tungsten arc welded dual-phase Fe50Mn30Co10Cr10 high entropy alloy

Article describes how in recent years, high entropy alloys (HEAs) have been shown to be promising alternatives to common engineering alloys, depending on their composition and thermomechanical processing. In the present work, Gas Tungsten Arc Welding (GTAW) was used to achieve defect-free joints based on a novel transformation induced plasticity (TRIP) Fe50Mn30Co10Cr10 HEA.

A modified aeroponic system for growing small-seeded legumes and other plants to study root systems (open access)

A modified aeroponic system for growing small-seeded legumes and other plants to study root systems

Authors of the article state that various growth systems are available for studying plant root growth and plant–microbe interactions including hydroponics and aeroponics. The aim of their study is to present step-by-step instructions for fabricating an aeroponic system, also called a “caisson,” that has been in use in several legume research labs studying the development of symbiotic nitrogen fixing nodules, but for which detailed directions are not currently available.

Corrosion Inhibition Effect of Pyridine-2-Thiol for Brass in An Acidic Environment (open access)

Corrosion Inhibition Effect of Pyridine-2-Thiol for Brass in An Acidic Environment

Article states that the inhibitive performance of pyridine-2-thiol added to a corrosive solution was investigated for brass using potentiodynamic polarization, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy. Scanning electron microscopy showed defect free and less scale formation for the inhibited surface but the bare brass surface had larger amounts of scale formation. X-ray photoelectron spectroscopy and UV-vis spectroscopy was used to investigate surface chemical composition and inhibitor structural changes over time.

Instructional Models for Course-Based Research Experience (CRE) Teaching (open access)

Instructional Models for Course-Based Research Experience (CRE) Teaching

This article presents a study that was done over a period of 3 years to explicate the instructional processes involved in teaching an undergraduate course-based research experience (CRE). The study presented here delineated a set of specific instructional practices used by active CRE instructors and modeled the relations between the use of these practices and specified outcomes. The resultant educational models should provide clarification of the ways in which the aims of CRE can be effectively achieved by instructors.

A gene-editing/complementation strategy for tissue-specific lignin reduction while preserving biomass yield (open access)

A gene-editing/complementation strategy for tissue-specific lignin reduction while preserving biomass yield

This article develops a method, using a single DNA construct that uses CRISPR–Cas9 gene editing to knock-out expression of an endogenous gene of lignin monomer biosynthesis while at the same time expressing a modified version of the gene’s open reading frame that escapes cutting by the Cas9 system and complements the introduced mutation in a tissue-specific manner. This method is applicable to any plant species in which transformation and gene editing are feasible and validated vessel-specific promoters are available.

Gene-based association tests using GWAS summary statistics and incorporating eQTL (open access)

Gene-based association tests using GWAS summary statistics and incorporating eQTL

Article proposes a powerful and computationally efficient gene-based association test, called Overall. Using extended Simes procedure, Overall aggregates information from three types of traditional gene-based association tests and also incorporates expression quantitative trait locus (eQTL) information into a gene-based association test using GWAS summary statistics. The results show that this newly developed method can identify more significant genes than other methods.

An Extreme X-Ray Variability Event of a Weak-line Quasar

Article reports the discovery of an extreme X-ray flux rise (by a factor of ≳20) of the weak-line quasar Sloan Digital Sky Survey (SDSS) J153913.47+395423.4 (hereafter SDSS J1539+3954) at z = 1.935. SDSS J1539+3954 is the most-luminous object among radio-quiet type 1 active galactic nuclei (AGNs) where such dramatic X-ray variability has been observed.

Encroachment order and spatial patterns of broad-leaf tree species in the naturalization of a Cunninghamia lanceolata plantation (open access)

Encroachment order and spatial patterns of broad-leaf tree species in the naturalization of a Cunninghamia lanceolata plantation

Authors of the article state that the aim of this study was to understand the encroachment order, spatial patterns, interspecific associations, and species diversity of a Cunninghamia lanceolata plantation and to provide context for how to improve the spatial structure of C. lanceolata plantations. Their results show that the encroachment of broad-leaf trees into the C. lanceolata plantation followed a clear successional sequence of tree community assembly: intolerant tree species encroachment first, such as Alniphyllum fortunei and Liquidambar formosana, encroached; neutral tree species then encroachment, such as Daphniphyllum oldhamii and Schima superba, and shade-tolerant tree species encroachment last, such as Castanopsis eyrei and Castanopsis tibetana.
