That said, a few of these look pretty interesting:
"Naked mole-rat mortality rates defy Gompertzian laws by not increasing with age"
"A lysosomal switch triggers proteostasis renewal in the immortal C. elegans germ lineage"
"How a mutation that slows aging can also disproportionately extend end-of-life decrepitude"
Harvard, the top biomedical institution, gets a score of 2,312.65. Alphabet (Calico isn't broken out), the #18th corporate institution, gets a 13.98, basically below all the major pharma companies. It wouldn't make the list of top 200 institutions overall. I didn't look closely at methodology, but it looks like it's counting publications in nature journals but doesn't weight for impact, which would surely up weight more prestigious institutions. That said, Alphabet/Calico/Verily's primary goal isn't necessarily to publish.
disclosure: I work at The Broad Institute (#66 institution, ha)
And Calico is not playing games to get published, like the typical lab in academia does.
