TL;DR: The results of this study are critical for understanding the clinical course of SARS-CoV-2 in a naturally susceptible host species, and for risk assessment.

TL;DR: This work identifies an enzyme, named Like Sex Four2 (LSF2), that hydrolyzes the phosphate group from the C3-position of glucosyl residues of starch, a novel enzyme involved in starch metabolism in Arabidopsis chloroplasts.

TL;DR: The field of serpins in arthropod biology is reviewed, providing an overview of current knowledge and topics of interest and the known structures of arthropody represent the serpin inhibitory mechanism and provide a detailed overview of the process.

TL;DR: In this paper, a mouse-adapted SARS-CoV-2 was serial passed through a clinical virus isolate in the lungs of mice and then used low doses of this virus in mouse models for advanced age, diabetes and obesity.

TL;DR: It is indicated that although different porcine cell lines are permissive to SARS-CoV-2, five-week old pigs are not susceptible to infection via oral/intranasal/intratracheal challenge and are not a suitable pre-clinical animal model to study Sars-Cov-2 pathogenesis or efficacy of respective vaccines or therapeutics.
