Article presents research where friction stir additive manufacturing technique was employed to fabricate AZ31B magnesium-hydroxyapatite composite. The study aims to evaluate effect of hydroxyapatite (HA, Ca₁₀(PO₄)₆OH₂), a ceramic similar to natural bone, into AZ31B Mg alloy matrix on biomineralization and biocompatibility.

This article proposes an urban nutrition (UN) extension to the previously published urban ecological economic system. The proposed extension can be used by decision makers worldwide to evaluate how landscape configurations and agricultural production systems affect the nutritional needs of the local population while fostering sustainable practices.

This article reports that in addition to the well-documented functional plasticity of the lingual salt glands, the middle of the three cloacal segments (i.e. the urodaeum) responds to increased ambient salinity to enhance solute-coupled water absorption in estuarine crocodiles (Crocodylus porosus).

This article analyzes the historical spatiotemporal behavior of the huemul (Hippocamelus bisulcus), an endangered deer endemic to Patagonia. Losing migratory traditions is a major threat, and may explain their presently prevalent skeletal diseases, reduced longevity, and lacking recolonizations for most remaining huemul subpopulations.

Authors of the article state that in the first step of their experiment, the sorption was investigated using La(III) ions before testing for the recovery of rare earth elements (REEs) from pretreated industrial acidic leachate. They infer that phosphonate groups participate in the sorption, and that the most effective sorption is at pH = 4.
