- A new Science paper, “Technological challenges and milestones for writing genomes” (Science 366:6463, 2019), was circulated; kanzure claims it omits attribution for prior work he contributed to the field.  
- c-c argues that the paper’s proposal for a “virus-proof mammalian chromosome” is biologically naïve, noting that endogenous retroviruses constitute 5–8 % of the human genome and are integral to mammalian biology.  
- kanzure counters that multi-virus resistance is feasible because many viruses rely on specific host tRNA pools; altering or removing those tRNAs can block viral replication.  
- superkuh highlighted two Nature Communications papers showing that expanding the physical space available to early mouse embryos increases telomerase access, yielding hyper-long telomeres and extended, healthier lifespans in the resulting mice (doi:10.1038/ncomms11739 and doi:10.1038/s41467-019-12664-x).  
- A parallel discussion explored a mutant neuropeptide S receptor reported in Science Translational Medicine that shortens sleep duration in humans while preserving memory consolidation (doi:10.1126/scitranslmed.aax2014).  
- adlai conducted an impromptu ethology experiment on local moth larvae, observing their self-built camouflage cases made from carpet fibers and dust, and speculated on repurposing the abandoned cases as thermal insulation.
