Hypoxic level and duration differentially affect embryonic organ system development of the chicken (Gallus gallus)
This article investigates how key organ systems are affected by hypoxia. The results indicated that either modest hypoxia (15% O2) throughout development, or hypoxia at any level during the late stages (d 11 to 18), increased the heart and chorioallantoic membrane weight, which partly compensated for the detrimental effects of hypoxia on embryonic development.

The Stability of Metallic MoS₂ Nanosheets and Their Property Change by Annealing
This article focuses on the effects of mild annealing on the structural and physical properties of the MoS₂ by heating the nanosheets in air and vacuum up to 350 °C. It was found that the annealing leads to an increase in resistivity for the nanosheets by 3 orders of magnitude, the appearance of two absorption bands in the visible range, and a hydrophilic to hydrophobic change in the surface wetting properties. Overall, this study provides another way to control the electrical, optical, and surface properties of MoS₂ nanosheets for fulfilling the needs of various applications.

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.
