A comparative pot study was performed to assess the toxic effects of copper (Cu) and/or zinc (Zn) contaminated wastewater (WW) irrigation on the growth, physiology, and element concentration of wheat grown for two months. The treatments included irrigation with uncontaminated wastewater (WW) as control, Cu-contaminated WW (CuWW), Zn-contaminated WW (ZnWW), and Cu + Zn contaminated WW (CuZnWW) in a completely randomized design. Compared to ZnWW, irrigation with CuWW or CuZnWW had severe effects on growth, physiology, and mineral absorption by wheat.

Catenated networks exclusively composed of intertwining rings were first envisioned as "Olympic gels" by Pierre-Gilles de Gennes four decades ago but have not been successfully prepared in artificial materials yet due to the challenge in synthesis. Herein, we present a bio-inspired, evaporation-assisted strategy to address this issue. In our design, the evaporation of liquid catalysts that induce ring-chain equilibrium of polymer systems drives macrocycles to encounter and assists their catenation through reversible cyclization.

The activin cascade is activated when a pair of extracellular ligand (Myoglianin, Myo; Activin β, Actβ; Dawdle, Daw) binds to two pairs of transforming growth factor β (TGF) serine-threonine receptor kinases, TGF-β type I (Baboon, Babo) and II receptors. However, the roles of activin way have not well been explored in non-Drosophilid insects. In the present paper, we compared the functions of Activin β (Actβ) ligand and receptor isoform BaboB in post-embryonic development in a defoliating ladybird Henosepilachna vigintioctopunctata.

Zika virus (ZIKV) is a flavivirus of significant epidemiological importance, utilizing various transmission strategies and infecting "immune privileged tissues" during both the pre- and postnatal periods. One such transmission method may involve extracellular vesicles (EVs). EVs can travel long distances without degrading, carrying complex messages that trigger different responses in recipient cells.
