Comment Re:La Niña is about to bite us in the arse (Score 1) 139

Be fair, "the greatest climate disaster" started long before Trump took office. It might even be before Lincoln. It's just that nobody noticed it at the time, because it's taken a long time to build. Trump may, however, be president at a point of inflection (a point, because you can't even roughly model it with simple quadratic function). Things are, indeed, likely to get worse quickly for a bit, but Trump didn't cause that, he's just been refusing to ameliorate it.

Sorry, but it's a reasonable request. It may also be reasonable to deny it, but it's a reasonable request. There's no way that a "driver" who's just been sitting there playing a game on his phone will be able to take over the driving in 10 seconds, so the steering wheel is useless in emergencies.

I think you're wrong. This is my perspective:

Sorry, but it's really "expect leaks". Every place has leaks. If your staff considers your actions immoral, then you should expect damaging leaks. If they are supportive, then you should expect supportive leaks. (They may actually be damaging, but their intended purpose will be to bolster your image. Similarly the "damaging leaks" may actually be harmless, or even useful, but their intended purpose would be to injure you.)

People are lousy at keeping secrets, even when they intend to...and they'd often rather seem to offer proof that they "know what's what".

Vetting your staff is supposed to ensure that they consider what you are doing as just and moral. The same as any criminal gang. (Note that I didn't mention legal.) That way when they leak it will be generally supportive.

No, that's not normal. 300 mg/day is well below the normal cardiac diet at a hospital. Every time she's admitted she has to fight with the diet kitchen to get food she can eat. People can have LOTS of variation in their needs, much more than is usually acknowledged even by those who are specialists in, e.g., diet, and certainly more than is usually acknowledged by non-specialists.

Yes, but at the time being discussed I'm not sure there is any evidence for the existence of ocean-viable boats. We're talking well back in the old stone age, and the Pacific near the Aleutians isn't peaceful. At later periods this would be a quite important point, and I'm rather sure that the inhabitants of the Kuril and Aleutian islands would prove to be related well back in time, but probably not far before the invention of the proto-kayak. (They might even not have gotten to the islands before then.)

Comment Re:I often think dietary "science" is a myth (Score 1) 270

There is a significant difference. Fizzy drinks chemically dissolve the teeth as well as feeding bacteria who do the same thing a lot more slowly.

Cokes are worse than fruit juice, and, unless you are on certain medications, unsweetened grapefruit juice (made from white rather than pink grapefruit) is probably good for you...in moderation.

FWIW, my wife is one of those people who are sensitive to salt...only in her case she's DRAMATICALLY sensitive to salt. She tries to keep her salt level at about 300 mg/day. I worried that this was dangerously low, but her doctor, after studying her blood level, said that she was keeping her sodium at precisely the correct level. This despite being on really aggressive diuretics (so much so that she is prescribed potassium supplements twice a day).

OTOH, I don't follow her diet, and probably had better not. So I use soy sauce and Tabasco sauce (green), and order things with normal spicing at restaurants. Most people would still consider my diet generally low sodium, but there are degrees and degrees.

My real point here is that different people can have quite different dietary needs. Don't assume that because something works for you it will work for someone else. It might, but it also might not.

Comment Re:Who paid for this study? (Score 1) 270

Actually it does preserve you as well. I was told during the Vietnam war that while Vietnamese corpses would decay grossly within a couple of days, US corpses lasted well for a week. I suspect some hyperbole there, but that's what I was told. The "informant" suspected BHA and BHT, but gave no evidence.

Now this doesn't say much about being healthy, but it seems to make for a well preserved corpse.

Comment Re:Drawing a long bow ... (Score 1) 235

I'd be reluctant to form that conclusion with the known (to me) evidence. How much of the bone fracture seems to have happened while the bone was fresh? If all, or most, then that's a reasonable point. If only a bit, then I suspect a sabretooth of the original fracture, and humans of much later work.

FWIW, I don't have access to Nature, and haven't looked at the article, so perhaps they explain this. And "fits within a broader pattern of Palaeolithic bone percussion technology in Africa, Eurasia and North America." seems to be including prior known North American patterns.

Certainly it's possible that the evidence is much better than I am assuming, but I'll wait for a consensus before assuming that. I sometimes for solid opinions on matters as much out of my field as this is, but I try to have solidly known evidence with agreed upon interpretations to base them on.

Comment Re:source (Score 1) 235

I'm not sure I buy skull morphology as being evidence of grammar. OTOH, there's evidence that chimpanzees have a rudimentary grammar sense, and they split off quite awhile ago.

If you want to say there isn't any better evidence offered for the development of language, that's plausible (though I'm not sure), but I don't find it really convincing. Particularly as it appears that chimpanzees can be taught language (rudimentary), they just don't teach it to their offspring. This might be related to the FOXp2 gene (a family that lost the human variant also lost language), but that's hard to pick out that far back...but I haven't heard that it influences skull shape.

IIUC, at certain of those periods there was an ice bridge between the continents. Such a crossing wouldn't have been very comfortable, but it might have been possible. And are there any plausible prey species (caribou?) that could have been being chased, and if so, what does their genotype show? When did horses cross from the Americas to Asia? If the timing works out, a herd of them could have been pursued back.

OTOH, all early human species were already quite inbred, so I doubt that population size was the kind of restriction it would currently be. (Lethal double alleles had probably already been eliminated.) So I'd favor their die-out being based around either bad luck (some lethal disease that when through their largely genetically identical population) or competition, either direct or indirect, with later immigrants who had better tools and social organization. Which could just have taken the form of being better hunters, so the game became both leery of humans and scarcer on the ground.
