- A photo of a temperature-sensitive color-changing cat (similar to Siamese cats) was shared as a biological example of real-time skin-temperature visualization, illustrating potential bio-inspired interfaces for human thermoregulation or health monitoring.  
- Discussion of a newly reported SNP (G allele) that appears protective against severe COVID-19, with the lowest allele frequency observed in Peruvian populations according to 1000 Genomes data, prompting debate about how many other SNPs might influence COVID severity.  
- jrayhawk noted that interferon acts as the primary detector for double-stranded RNA, suggesting that genetic variants affecting interferon pathways could be among the most significant determinants of COVID-19 outcomes.  
- A Science paper (DOI 10.1126/science.abh4049) and accompanying press release were highlighted for describing a Chinese team’s achievement of cell-free, chemoenzymatic starch synthesis directly from carbon dioxide—an advance that could decouple food production from agriculture and enable closed-loop carbon utilization.
