Stand up to action: The postural effect of moral dilemma decision-making and the moderating role of dual processes.

Psych J 2021 Apr 21. Epub 2021 Apr 21.

Department of Psychology, School of Social Sciences, Tsinghua University, Beijing, China.

Previous studies have demonstrated the possibility that when people are in standing rather than sitting postures, they have a stronger cognitive control propensity, making them inclined to agree more to sacrificing one innocent person and saving more people. Furthermore, this postural effect can be moderated by dual processes. In three studies, participants read dilemma scenarios followed by a proposed behavior to sacrifice one innocent person and save five or more people. Read More

A three-dimensional vertex model for Drosophila salivary gland invagination.

Phys Biol 2021 Apr 21. Epub 2021 Apr 21.

The University of British Columbia, 1984 Mathematics Road, Vancouver, British Columbia, V6T 1Z4, CANADA.

During epithelial morphogenesis, force generation at the cellular level not only causes cell deformation, but may also produce coordinated cell movement and rearrangement on the tissue level. In this paper, we use a novel three-dimensional vertex model to explore the roles of cellular forces during the formation of the salivary gland in the Drosophila embryo. Representing the placode as an epithelial sheet of initially columnar cells, we focus on the spatial and temporal patterning of contractile forces due to three actomyosin pools: the apicomedial actomyosin in the pit of the placode, junctional actomyosin arcs outside the pit, and a supracellular actomyosin cable along the circumference of the placode.

Neutralism versus selectionism: Chargaff's second parity rule, revisited.

Genetica 2021 Apr 20. Epub 2021 Apr 20.

Department of Biomedical and Molecular Sciences, Queen's University, Kingston, ON, K7L3N6, Canada.

Of Chargaff's four "rules" on DNA base frequencies, the functional interpretation of his second parity rule (PR2) is the most contentious. Thermophile base compositions (GC%) were taken by Galtier and Lobry (1997) as favoring Sueoka's neutral PR2 hypothesis over Forsdyke's selective PR2 hypothesis, namely that mutations improving local within-species recombination efficiency had generated a genome-wide potential for the strands of duplex DNA to separate and initiate recombination through the "kissing" of the tips of stem-loops. However, following Chargaff's GC rule, base composition mainly reflects a species-specific, genome-wide, evolutionary pressure. Read More
