Birth of Oswald Avery
Oswald Avery was born in 1877. With MacLeod and McCarty he showed, in a paper dated 1 February 1944, that the transforming substance of pneumococcus is DNA, not protein.

Peer-reviewed vector illustrations, macromolecular structures, and metabolic pathway maps from across all 23 biological disciplines.
The bacterial cell envelope is the defining structural barrier separating Gram-positive from Gram-negative bacteria. Gram-positive bacteria feature a thick, multilayered peptidoglycan mesh rich in teichoic acids, whereas Gram-negative bacteria possess a thin peptidoglycan layer enveloped by an asymmetric outer membrane containing lipopolysaccharide (endotoxin), dictating antibiotic susceptibility and pathogenesis.
Nanoscale molecular engines, ancient viral domestications, and evolutionary paradoxes explained through peer-reviewed biochemistry and cell biology.
Sequencing one human or one bacterium doesn't tell you the species' genome; *E. coli* has a pan-genome containing over 16,000 unique genes.
The Pan-Genome consists of: (1) The Core Genome (genes shared by 100% of all isolates, encoding essential translation and metabolic machinery); and (2) The Accessory/Dispensable Genome (genes present in only a subset of strains, encoding niche-specific traits like antibiotic resistance, toxins, and novel carbon utilization). In *E. coli*, any two random strains share only ~50% of their genes!
The Human Pangenome Reference Consortium (HPRC) recently released the first human pangenome graph, replacing the single linear reference genome with a diverse, multi-ethnic graph!
