Bret Weinstein on "The Portal" (w/ host Eric Weinstein), Ep. #019 - The Prediction and the DISC.
About this video
A long Portal podcast episode in which Bret Weinstein tells Eric Weinstein the story of his lab mice telomere work, the prediction behind it, and what it means for science and aging.
Why it appears in the archive
HN recommends it as the full account of the lab mice issue and evolutionary tradeoffs between cancer and longevity, despite its length.

>The core claim he makes "all mice are broken" is a hyperbole that a lot of people will tell you is unsubstantiated. He makes it sound like all tests done on mice are flawed because of it. It isn't hyperbole, if Bret's claims are substantiated. The claims being that most lab mice are from the Jackson lab, that all of their mice have extremely long telomeres compared to wild mice, and that this could have serious implications on the potential harm to humans by some drugs - even while also accounting for the fact that mice are already not a good model of humans and that the same drugs are later tested on humans. (I could elaborate on this, but it's covered thoroughly in the paper and podcast.) I agree Eric hasn't satisfactorily proved they didn't change the protocols, but if it is the case that all of their mice still have long telomeres, and if all of the other claims are true (most US researchers still using those mice + the other claims), then the claims "most mice used by US researchers are broken" and "most tests done on mice by US researchers are flawed because of it" are likely also true. I have no idea if the above claims are true, of course, but they should be investigated on their merits.

Read original comment ↗They go over multiple topics. Check the top comment for timestamps. If you want to hear the full story I suggest listening to this podcast episode: [VIDEO] . It's long, but I found it very interesting.
Read original comment ↗According to Bret Weinstein who figured out the connection between telomere length and breeding, they seem to have quietly changed the breeding protocols to bring the telomere length back down to be in line with wild type mice. He talks about it in a long interview that gets really interesting about a hour in: [VIDEO]
Read original comment ↗Uh oh, mice in labs are not like humans in this regard at all. Lab Mice have extraordinary cell repair capabilities. My guess is that the AKG slows down cell division. This podcast delves into the problem with lab mice and explains the trade offs that happen on an evolutionary and cellular level in mice with regards to longevity. [VIDEO]
Read original comment ↗The answer is yes. It seems the author is reasoning more in the philosophic realm than in evolutionary biology. In this podcast [1] an evolutionary biologist goes into depth about telomeres, evolution and how cancer and longevity are two sides of the same coin. Long story short, having cells die after a number of replications is a postive trade off. It means that when a cell replicates too fast it also dies fast. The opposite are cancer cells, which replicate too fast and don't die. [1] [VIDEO]
Read original comment ↗I recommend the book: Rigor Mortis: How Sloppy Science Creates Worthless Cures, Crushes Hope, and Wastes Billions Generally, all scientific fields have immense issues related to the walled gardens and limitations created by their peers. I also recommend this discussion between Eric and Brett Weinstein which highlights just one example of the major issues: [VIDEO]
Read original comment ↗The publications section on Bret Weinstein’s Wikipedia page [1] lists the paper [2][3]: > Weinstein, Bret S; Ciszek, Deborah (2002). "The reserve-capacity hypothesis: Evolutionary origins and modern implications of the trade-off between tumor-suppression and tissue-repair". Experimental Gerontology. 37 (5): 615–27. There doesn’t seem to be a succinct write up on how this hypothesis led to Carol Greider’s 2009 Nobel Prize [4]. Greider did not recognize Weinstein’s contribution [5].

Read original comment ↗There was an interesting claim I heard from Eric Weinstein regarding peer review that he characterized as a cancerous infiltration into all of science from some medical area? Aha, found it in my notes... """ 1:32:28 Eric: but let me jump in--peer review is a cancer from outer space. It came from the biomedical community, it invaded science. The old system, because I have to say this because many people who are now professional scientists have an idea that peer review has always been in our literature and it absolutely [mff __ ] has not. Bret: right Eric: Okay. It used to be that the editor of a journal took responsibility for the quality of the journal which is why we had things like nature crop up in the first place because they had courageous, knowledgeable, forward-thinking editors. And so I just want to be very clear because there is a mind virus out there that says peer review is the sine qua non of scientific excellence, yada, yada, yada, bs, bs, bs. And if you don't believe me go back and learn that this is a recent invasive problem in the sciences. Bret: recent invasive problem that has no justification for existing in light of the fact Eric: Well not only does it have no justification for existing... When Watson and Crick did the double helix and this is the cleanest example we have. The paper was agreed should not be sent out for review because anyone who was competent would understand immediately what its implications were. There are reasons that great work cannot
