basically, if you decrease that insulin signaling pathway, then FOXO3 is always active in those worms, and they live like 100% longer.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
and here's the thing about that data and this is what I think if you get rid of another gene that's homologous to fall so - Oh deaf sixteen is right that's too far completely obliterates the lifespan extension meaning it's the Fox o3 that seems to be really important for we have how many we have for foxes yeah you mean different fox genes okay yeah I don't know exactly how many but the Fox oh we have three we have one two and four was it one two and there was our one two four or five but but their analog is sixteen I remember that right there daf-16 is basically our Fox Oh Fox oh yeah so okay well anyways yeah I'm not sure I'm getting confused with you know this but what is interesting is that the lifespan extension was completely like ameliorated
the cancer reduction didn't depend on Fox or 3 only the lifespan extension
and daf ii ended up being the analog of the igf receptor and i think daf 16 was basically an analog of fox03a or 3b i can't recall yeah it wasn't quite the receptor it was the thing that the receptor turned on but it's one one step downstream one step downstream inside yeah
if you knocked out that Gene you could double the lifespan from roughly two weeks to four weeks or four weeks to eight weeks I forget what it was of uh C elegans this worm
when some very seminal and interesting work was published looking at the daf 16 mutation in or maybe it was daf2 I can't remember if it was daf2 first or daf 16 but it was the analog of the igf receptor and if you knocked out that Gene you could double the lifespan from roughly two weeks to four weeks or four weeks to eight weeks I forget what it was of uh C elegans this worm
