Article presents research on oxalate catabolism in plants.

Article presents a study utilizing a carefully selected sample of 53 radio-quiet quasars that have Hβ and C iv λ1549 spectroscopy as well as Chandra coverage, to search for a robust accretion-rate indicator for quasars, particularly at the highest-accessible redshifts (z ∼ 6–7).

This article evaluates the role that gene-environment interaction between air-pollution and Alpha-1 Antitrypsin (AAT) genes plays in the severity of COVID-19. Results find parallelism between the number of COVID deaths and the AAT*air pollution global risk in Europe.

Article studying Hydrogen-bonded pyridine–water mixtures by a time-frequency resolved coherent Raman spectroscopic technique.

This article presents research on genetic and biochemical analyses that shows ANR has dual activity and is involved not only in the production of (−)-epicatechin starter units but also in the formation of 2,3-cis-leucocyanidin to serve as (−)-epicatechin extension units. The results find that differences in the product specificities of ANRs account for the presence/absence of PA polymerization and the compositions of PAs across plant species

Article is a study exploring the possibility of using the tobacco retrotransposon Tnt1 to create a transposon-based insertion mutant population in B. distachyon.

Article reports light induced charge separation in a newly synthesized triphenylamine–thiophene-Sc₃N@Iₕ-C₈₀ donor–acceptor conjugate and its C₆₀ analog, triphenylamine–thiophene-C₆₀ conjugate, and the significance of the thiophene spacer in promoting electron transfer events.

This article is the first to present data on the migratory movements of the “large-billed” subspecies, F. a. naumanni, that breeds in the high Arctic and which has significantly larger body size than those farther south.

This article shows that both Cys-EC and 4β-(S-cysteinyl)-catechin (Cys-C) are present in grapevine. The data from this study advance knowledge of PA building blocks and LAR function and provide targets for grapevine breeding to alter PA composition.

Article presents a combination of first principles and quantum ballistic transport calculations to shed important insights from an atomistic viewpoint on the underlying mechanisms governing spin transport in graphene/ CrI₃ junctions.

Article discusses how Antarctica's response to climate change varies greatly both spatially and temporally. The authors used a 43-year record of Antarctic snow melt seasons from space-borne microwave radiometers with a machine-learning algorithm to show that both the onset and the end of the melt season are being delayed.

Article describes how soil moisture (SM) and atmospheric humidity (AH) are crucial climatic variables that significantly affect the climate system. However, the combined influencing mechanisms of SM and AH on the land surface temperature (LST) under global warming are still unclear. The authors systematically analyzed the interrelationships among annual mean values of SM, AH, and LST using ERA5-Land reanalysis data and revealed the role of SM and AH on the spatiotemporal variations of LST through mechanism analysis and regression methods.

Article describes how, in many raptor species, hatching asynchrony results in a size hierarchy among nestlings, which may facilitate brood reduction by means of sibling aggression-induced mortality, especially in times of low food resources. The authors studied the influence of hatch rank, brood size, and brood age on aggression and feeding rates among Red-shouldered Hawk (Buteo lineatus) nestlings in suburban southwestern Ohio.

Authors of the article explain that they investigated the extreme X-ray variability of a z = 1.608 active galactic nucleus in the 7 Ms Chandra Deep Field-South (XID 403), which showed two significant X-ray brightening events.

Authors of the article assert that they studied the ensemble X-ray variability properties of active galactic nuclei (AGN) over large ranges of timescale (20 ks ≤ T ≤ 14 yr), redshift (0 ≤ z ≲ 3), luminosity (1040 erg s−1 ≤ LX ≤ 1046 erg s−1), and black hole (BH) mass (106 ≤ M⊙ ≤ 109). The authors show that the data collected from archival observations and previous literature studies are fully consistent with a universal PSD form, which does not show any evidence for systematic evolution of shape or amplitude with redshift or luminosity, even if there may be differences between individual AGN at a given redshift or luminosity.

Authors of the article assert that rate coefficients, k1(T), for the gas-phase reaction of the OH radical with Furan-2,5-dione (maleic anhydride (MA), C4H2O3), a biomass burning related compound, were measured under pseudo first-order conditions in OH using the pulsed laser photolysis - laser induced fluorescence method over a range of temperature and bath gas pressure. Their results are compared with a previous room temperature relative rate study of the OH + MA reaction and significant discrepancy between the studies is discussed. This is the accepted manuscript version of the published article.

Article describes how analysis of FAAHs from multiple angiosperm species, which revealed two conserved phylogenetic groups that differed in key conserved residues in the substrate binding pocket. The authors combined computational and biochemical approaches to compare the structural and enzymatic properties of two FAAH isoforms in the legume Medicago truncatula designated MtFAAH1 MtFAAH2a.

Article comments on the claims made by the authors of the original article. The authors of the commentary note flaws in the DFT-based methodology and the commentators describe differences between their application and the original article's described application.
