Yes it is mostly related to nitrosamines. The thinking has shifted a bit in the last years, it seems and there is some lit suggesting that cured meats are not necessarily a higher health risk than regular meat. OTOH the health baseline has shifted a bit with general overconsumption of meat as well as ubiquitous presence of overprocessed foods so I guess that particular risk might be difficult to tease out. Moreover, in a healthy diet nitrates are generally derived from plant material (ca. 5% would be meat-derived). Also, quite a few traditionally cured meats are salted and dry-cured (e.g. capocollo).

Cosmological Redshift and metric expansion

Your welcome likely tonight I will setup the derivatives of how the equations of state are determined via the ideal gas law relations to help you better understand how thermodynamics are applied. -
Cosmological Redshift and metric expansion
AbstractDreamer replied to AbstractDreamer's topic in Astronomy and Cosmology
Thank you all for being really specific and pedantic in your wordings. I genuinely need this to help understand with more clarity as I know words are a poor substitute for maths. I will take some time to absorb all this so I can pose questions that make more sense in terms of real physics and mathematics. -
Interesting. Yet nitrites as preservatives, e.g. in cured meat products, are regarded as unhealthy, I gather. But that, I dimly seem to recall, is due not to the nitrites per se but to the nitrosamines they produce in the meat, which are possible carcinogens. If I’ve remembered correctly how this works… (Have to confess my son and I have been eating French rosette sausage and Italian coppa for lunch most days in the last fortnight, while we are on holiday in Brittany, promoting the odd twinge of conscience.)

No, but there is increasing evidence on the impact of nitric oxide deficiency on vascular health (as well as in the nervous system). I should add that the issue of nitrate reducers only came up in the context with antiseptic mouthwashes. To clear up some confusion, (also in response to Luc Turpin), there are generally two major routes of NO production. The first is produced by our bodies via the NOS pathway (derived from arginine). Nitric oxide itself regulated in part by oxidation to nitrate which contributes a bit to local nitrate pools. NOS-independent production can be initiated by commensals in the the mouth, which is mostly reduction of nitrate to nitrite, and the latter can be further reduced to NO non-enzymatically (which would also apply to dietary nitrite). In parallel, gut bacteria are also known to reduce nitrate, but in this case completely to NO. Going back to OP, there is limited data that suggest that mouth wash would significantly disrupt NO metabolism, though it certainly could make things worse for folks who already have issues in that regard.

Is US higher education the best in the world?
John Cuthber replied to Otto Kretschmer's topic in Science Education
No. So what? Were you not aware of the phrase? https://en.wikipedia.org/wiki/Times_Higher_Education higher education /ˌhʌɪə ɛdjuːˈkeɪʃ(ə)n/ noun education at universities or similar educational establishments, especially to degree level. -
Beet juice is great. Associated with increased mitochondrial activity. I find the lift is similar to a demitasse of coffee and seems to last most of the day. I recall Sterno aka Canned Heat was sometimes consumed during Prohibition in the US. Denatured by adding methanol to the alcohol portion, plus a gelling agent, so that people would not drink it and (post Prohibition) the company didn't have to pay the alcohol tax. But desperate people would squeeze out the gel through a sock and then drink the liquid, suffering toxicity and sometimes blindness. I remember it was nicknamed "squeeze" because of the filtering method. An amphoteric oxide was used to gel the mixture. Which one IDK. Footnote: I learned the term "squeeze" from Crichton's novel The Andromeda Strain, wherein the village drunk is a Sterno drinker, and as a result, one of the only survivors. The alien bug is apparently not able to grow in a person who is acidotic, so the drunk and a screaming baby are the only survivors. Methanol causes tissue acidosis.

What can and should be done to address the world overpopulation crisis?
TheVat replied to JohnDBarrow's topic in Politics
This is your take on a spiritual path that postulates reincarnation? Keeping the stuff? Seriously? Somehow I don't see the Wheel of Karma as focused on real estate. With that attitude, maybe your soul needs the bracing spiritual challenges of surviving in some future Gaza. Or at least some place where helping your community is valued more than marble countertops and bling. -

Evolution of religiosity
iNow replied to Otto Kretschmer's topic in Evolution, Morphology and Exobiology
Religiosity is most likely tied to our tribal tendencies and adherence to group norms and mores. Members of the tribe who acted and behaved in ways contrary to local social expectations tended to find themselves ostracized or separated from the group and so consequently lost access to food, protection, and access to mates for reproduction (I.e. they were selected against). Cooperation and shared explanatory narratives fed cohesion, basically. Belief in god(s), however, is slightly different than religiosity and is far more likely related to our abilities around mental rehearsal of interactions with unseen others and our tendency while young toward accepting stories from parents and tribal elders.- 1 reply

Neither, A Single Death Is a Tragedy; A Million Deaths Is a Statistic, this statement isn't as harsh as it seems to be, whomsoever said it; we can't predict the action of a single human, but we can, with some precision, predict the actions of the average human; which is just as true today as when Assimov ventured his idea of psycohistory.

Cosmological Redshift and metric expansion
Mordred replied to AbstractDreamer's topic in Astronomy and Cosmology
I would like to clarify one detail. The vacuum can have numerous connotations. For example the Einstein vacuum (devoid of all particles including virtual) which is the vacuum solution. Is different than the way vacuum is applied in the FLRW metric. In the FLRW metric vacuum is the relation between the kinetic energy and potential energy terms of a scalar field using the scalar field equation of state. Example w=-1 for the Cosmological constant. This value specifically -1 describes a constant incompressable fluid with negative pressure. Inflation would have a different value but can slow roll to the value for the cosmological constant (you may see that in the case of Higgs inflation where the cosmological constant term is also considered being due to the Higgs field) Another detail is that curvature can also mean slightly different things. For example extrinsic and intrinsic curvature. You can also have curvature independent of coordinate or coordinate choice or curvature that has a coordinate dependency. An example of the latter. Is the localized curvature term due to gravity. It is dependent on the location. (Localized anistropy) -
As it relates to the topic and my interlocutor @Moontanman this best describes the situation, My karma ran over your dogma. All I was trying to do is explain the value of acceptance in a balanced 'world view' and by extention a more philosophical approach to life. IOW my moment of awe (doesn't match other's), which for me happened when I said to my dog, who was obviously disapointed when we walked past the turning of her favorite route, "you wouldn't be so disapointed, if you didn't expect to go that way.". Unfortunately, I don't speak dog either... 😣 Apologies, it's a habit of mine to automatically add an at when referring to the members of our little club. 🙏

Why take this as gospel? Ehrlich has been quite spectacularly wrong about a number of his predictions. Nobody has disagreed with this; we are discussing finite numbers. -
