A novel nano-particle strengthened titanium alloy with exceptional specific strength
This article microstructurally tailors an exceptionally high-strength titanium alloy, Ti-6Al-2Sn-4Zr-6Mo (Ti6246) through friction stir processing (FSP) in order to provide enhanced weight savings and improved fuel efficiency. The specific strength attained in one of the conditions is close to 450 MPa mÂł/mg, which is about 22% to 85% greater than any commercially available metallic material. This novel nano particle strengthened Ti alloy is a potential replacement for many structural alloys, enabling significant weight reduction opportunities.

Physical and optical properties of the International Simple Glass
This article presents physical property data (both published and previously unpublished) on a single batch of International Simple Glass (ISG), which was cast into individual ingots that were distributed to the collaborators. Properties from the atomic scale to the macroscale, including composition and elemental impurities, phase purity, density, thermal properties, mechanical properties, optical and vibrational properties, and the results of molecular dynamics simulations are presented, as well as information on the surface composition and morphology after polishing. Although the existing literature on the alteration of ISG is not extensively reviewed here, the results of well-controlled static alteration experiments are presented here as a point of reference for other performance investigations.

Effect of MS222 on Hemostasis in Zebrafish
Article studying the effect of MS222 on hemostasis in Zebrafish. The authors performed various assays and find that Hct values, the amount of blood collected, bleeding, and coagulation differ significantly between anesthetized and nonanesthetized fish. These results suggest that blood collected after MS222 anesthesia of zebrafish has altered hemostasis.

Combining loss of function of FOLYLPOLYGLUTAMATE SYNTHETASE1 and CAFFEOYL-COA 3-O-METHYLTRANSFERASE1 for lignin reduction and improved saccharification efficiency in Arabidopsis thaliana
This article tests if lignin content can be further reduced by combining genetic mutations in C1 metabolism and the lignin biosynthetic pathway by generating and functionally characterizing fpgs1ccoaomt1 double mutants. The observations demonstrate that additional reduction in lignin content and improved sugar release can be achieved by simultaneous downregulation of a gene in the C1 (FPGS1) and lignin biosynthetic (CCOAOMT) pathways.

LBD29-Involved Auxin Signaling Represses NAC Master Regulators and Fiber Wall Biosynthesis
This article uses a large-scale mutant screening to identify a dominant activation-tagging mutant, fiberless-d (fls-d), showing defective SCW development in stem fibers, similar to that of the nac secondary wall thickening promoting factor1-1 (nst1-1)nst3-3 double mutant. The results demonstrate auxin is upstream of LBD29 in repressing NAC master regulators, and therefore sheds new light on the regulation of SCW biosynthesis in Arabidopsis.

Embryonic developmental oxygen preconditions cardiovascular functional response to acute hypoxic exposure and maximal β-adrenergic stimulation of anesthetized juvenile American alligators (Alligator mississippiensis)
Article investigating the effect of embryonic hypoxia on the cardiovascular phenotype of 4-year-old American alligators (Alligator mississippiensis). The findings indicate that embryonic hypoxia in crocodilians alters the cardiovascular phenotype, changing the juvenile response to acute hypoxia and β-adrenergic stimulation.

Victims of "adaptation": climate change, sacred mountains, and perverse resilience
This article proposes the concept of "perverse adaptation", where one actor or institution's adaptation to climate change in fact produces aftershocks and secondary impacts upon other groups. Drawing on ethnographic and sociolinguistic research in northern Arizona regarding artificial snowmaking at a ski resort on a sacred mountain, the author elucidates resort supporters' and others' attempts to frame snowmaking as a sustainable adaptation to drought (and, implicitly, climate change) while counterpoising these framings with narratives from local activists as well as Diné (Navajo) individuals.
