OK, so much for that theory because I went ahead and searched the full text for wine and got this:

Mosquitoes showed a clear preference for the well-hydrated, on hops and grapes, that is. Arm landings were significantly higher in beer drinkers compared to those who had nobly abstained for at least 12 hours (FC 1.44, 95% CI 1.20-1.74, PFDR < 0.001, Figure 3C). Mosquitoes seemed to have a taste for wine drinkers too (FC 1.39, 95% CI 1.02-1.88, P = 0.035), but this effect sobered up after correcting for multiple testing (PFDR = 0.103). Measured blood alcohol concentration ranged from to 1.82â and positively correlated with the self-reported consumed number of beers (Spear-man rho = 0.46, P < 0.001) and glasses of wine (Spearman rho = 0.12, P = 0.011). No statistically significant effect of alcohol concentration was observed on mosquito attraction when included as a continuous variable (FC 1.04, PFDR = 0.853) nor as a binned variable using the concentration of approximately two units as a threshold (< 0.5â versus 0.5â, FC 1.21, PFDR = 0.344). Individuals reported to have smoked cannabis in the past 48 hours were more attractive to mosquitoes than individuals that did not smoke cannabis (FC 1.35, 95% CI 1.09-1.66, PFDR = 0.017, Figure 3D). Cannabis was the only substance for which an effect on mosquito arm-landings was found, the effects of other substances were statistically not significant (all PFDR > 0.569). There was no indication that the presence of a cannabis user made mosquitoes fly at higher altitudes or made them less aggressive.

Now I'm on to a new idea. Since hops and cannabis are related, there may be some aromatic compound common to both of them.

The drug companies didn't invent dementia. Alzheimer's was described in1906 and named in 1910, but there was a broad understanding before of older people going in to mental decline--even in ancient times. There's always going to be a leading cause of death. Increased health will lead to increased life spans and reveal new problems. That's what happened with senile dementia. More old people, so more people get it. Those same doctors and drug companies are working on cures and treatments ad yes treatments are more likely to come before cures. Take HIV for example. I'm pretty sure the people maintained at undetectable levels, leading near normal life spans are happier than when they got full-blown AIDS and it was a death sentence. Yes. There's still no cure and the drugs cost money; but they haven't stopped work on a cure. Any researcher in the field would be absolutely THRILLED beyond belief to have their name attached to that, or a cure for Alzheimer's. It's just that it's a really hard thing to do.

Yes. Alcohol. It's on their breath, and insects are attracted to it in general. Googling around, that includes mosquitos but I've heard of people using it to attract wasps and kill them even though it's probably counter-productive since you're attracting the very thing you don't want and the outdoors have a very large supply that your bug zapper or dish of beer is not going to exhaust.

I have a Powershot A640 I bought in '06 or '07. I don't recall. It kind of sucks in low light and lacks image stabilization. Otherwise I'm pretty happy with it. It isn't broken, so it hasn't been replaced. 10 MP is fine for me. I'm not a pro so I don't need more. I heard some of these cameras might be considered "vintage" now, but the last time I checked mine's not worth much so I just use it for its intended purpose. The case I used to attach to my belt wore out before the camera, so now I toss it in my daypack like a trooper and it's still not broken.

Comment Let's make a list (Score 1) 76

We all know it when we see it. Grinding is processing. The nixtimalization process for corn is processing and it's GOOD, because without it you don't get enough nutrients. American Indians did it. You could do it in your own kitchen if you had to. You saute, puree, grind, and mix all the time in a home kitchen. These are processes, but they're not ultra-processing.

You know what I've never heard of anybody doing at home? Hydrogenating. Partially or fully, nobody does that shit in their kitchen. So. First item on the list: hydrogenated oils.

You might buy something like Crisco which is hydrogenated oil, but you'd never make it yourself so yes, even a tub of that "ingredient" is an ultra-processed food as far as I'm concerned. Anything that contains it is ultra-processed, so you can make ultra-processed food in your kitchen by using that as an ingredient; but you didn't make it yourself from normally processed ingredients. Pressing the oil from a seed is normal processing. It may or may not be good; but it's closer to the original healthy ingredient as opposed to something that's ultra-processed.

This is how it's going to go with the list in general--there will be debates about what should and shouldn't be on it; but there should be guidelines about how the decisions are made. Whether or not it's a common process from raw ingredients, normally done in home kitchens is a pretty good guideline to start with.

I think the point about them being a kind of "gateway drug" to infotainment screens is valid though. If the cameras weren't required, would modern cars have infotainment screens as much as they do? I recently drove a rental car with backup camera and found it more annoying than anything since I've been driving for decades now without one. Neither my current ride nor the rental were a big SUV/truck though. Some of those don't just need backup cameras. They probably ought to have hood cameras. A kid or even a short adult can walk in front of some of these trucks and not be seen.

Comment Re:China is like Hamas (Score 1) 103

No. China is nothing like Hamas, because it's strong and doesn't need to engage in asymmetric warfare. China doesn't put its children in harm's way and spend 10 years provoking its neighbors and using the response to gain sympathy at universities and on new media.

China isn't like Israel either. It doesn't squander its goodwill frivolously. It doesn't fall in to traps set by the likes of Hamas, and if it's going to make a move that anybody might describe as "genocide", it makes clear that it doesn't care what we think while simultaneously finding ways to keep it out of the media just in case it does matter what people think. Does anybody even know what I'm referring to, and if you do have you seen a story about it in the last six months? That's how good they are.

Comment Making it a generational war won't help (Score 4, Insightful) 238

Making this a generational war isn't going to help. It deflects from the real culprits: The financial industry and the colleges themselves. The incentive for the finance biz was obvious. It's another payment stream, and they got the cherry on top of it not being discharged in bankruptcy. The incentive for colleges is that when education is financed, it now makes it possible for them to raise tuition and other expenses. When you pay out of pocket, you're cost conscious. When something is financed, you're tempted to price it according to whatever payment you think you can afford in the future. Even if you don't, other people do and that will allow prices to rise. You're a price-taker in the market. You have no choice, except to turn away or maybe go with something cheaper and perhaps less prestigious; but that's going up too because everything is financed.

So it's not inter-generational conflict. That's deflection, and before some young socialist yells "class war!" that's not it either. Everybody is greedy. Socialism is just an alternative marketing plan developed by another bunch of suits, with an aim of going straight for power and relying less on money to get there.

So what's the answer? Rooting out corruption and greed, without regard for the cynical fronts of "generational war" or "class war", or whatever "war" is being pitched to accrue power to yet another bad actor.

Submission + - Another large Black hole in "our" Galaxy (arxiv.org)

RockDoctor writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.
