The 40 to 55% of HFCS that isn't Fructose is Glucose, which triggers insulin production immediately when it reaches the small intestine and is transported into the bloodstream before the insulin reaches it - Insulin is then needed to transport the glucose out of the bolldstream and into muscles and other tissues. Sucrose has to be cleaved first into glucose and only starts triggering insulin production after cleavage by other enzymes. This means, qat the very least, that Sucrose gets farther into the intestine before triggering insulin production, and that the rate of production is limited by the rate at which the sucrose is split and not the much faster rate at which glucose enters the bloodstream. I really don't see how you can call those two processes identical. Note I'm not saying that its been proved the differences in how high and low insulin levels and blood sugar levels get necessarily means there's a difference in health consequences, but its certainly not impossible just because of the fact both forms of sugar get to the same organ before digestion. And what about the part that is Fructose? That's certainly dealt with separately.

It's possible there are as yet unknown natural laws. It's even possible that there are natural laws our species is just too dumb to discover, ever. But the chance of undiscoverable laws is lower than the more general chance of as yet undiscovered laws.
            In the same way, the chance that there's an as yet undiscovered law which applies to this particular technology, and which has certain properties making it at all likely it gets inadvertently followed sometimes is possible, but is an accumulation of low probablility circumstances, and so has very low overall likelyhood. It's generally more likely that any undicovered laws will be ones where they consistently block getting the technological configuration right. For a simplified example, if there's some undiscovered property of, say, Tungsten, then it's likely to become apparent when people note that all the claims for success come from experiments where tungsten was used for a particular stage of the process in a particular way. There's much less chance that simply having a certain mass of Tungsten within a certain number of feet of the device, whether it's made into a part of the apparatus or light bulb filaments, will make the experiment very likely to succeed in either case.
        Try to describe a hypothetical law that works in such a way it is very hard to spot a pattern or regularity that will lead the researchers to really formally formulating that law, but makes a big enough difference that it determines general success or failure much more than many other variables. Try to craft such a genuinely new law for explaining anything, from apiary colony collapse disorder to zebra camoflage evolution*. I'll bet this results in a very long, convoluted law to explain all the conditions. That's what usually happens with novel approaches - sure every once in a while one pays off big time, but not every discovery is Special Relativity. If you end up with a long formulation, full of various clauses which make it fit all the observations, then what you have is a chain of things, and if any link of that chain is wrong, the whole formulation collapses. If a chain is really only as strong as its weakest link, then a very lengthy chain of logical inferences is a chain with a very low probability of being right.

* why do Zebras have stripes when one of their predators in roughly the same size range has polka-dots (Leopards)?, and another one even closer to Zebras in size is solidly colored (Lions)? Try to develop a new law relating to natural selection that rules out any possibilitys that this is simply happenstance, and yet that doesn't predict what sorts of camoflage any other species should display in case some of the facts don't fit that case.

Are they talking about general relativity equations?
That's included, but I think the article and summary are actually getting it right for once. The equations in question are ones that reconcile GR with Quantum Mechanics, and that, in general, means variations on various String or Brane Theories, and quite possibly specifically Supersymmetry, if that's not being completly discarded by the researchers just because CERN is finding preliminary evidence that the simplest and lowest energy Supersymmetry model doesn't work. It's possible some alternatives to those models can also be tested and refined or dismissed, but either way, we really are looking at math where complexity increases result time very, very rapidly. Here's a link for an example of some math used for both Supersymmetry and more general String Theory calculations - If you look at the section specifically about "Stringy theories" calculations, there's a good example of a formula that's obviously, by simple inspection, prone to grow very quickly with added terms for more complex situations, and there's some other quite good examples in the lead up to that section.

I'm sure that the parent poster can define their own use of the term "rent seeking", but in case you're genuinely unaware of the more common uses of the term, in general, it involves taking a situation where an item or good is normally fully owned by the person who bought it, and making it a situation where the item or good is somewhat changed, so that it must be paid for by perpetual fees, without the payer gaining all the rights they had in the older situation. "Rent seeking" is not the same thing as merely choosing a rental model for seeking profit, rather it's placing blocks before those potential customers who want to instead own the good or item and all the rights that are normally associated with owning that particular item..

                For example, if I own a physical copy of a book, one of the things I may value is that I can use that copy to detect when someone edits the text of a new edition to change what the author actually wrote, particularly if that change is to the author's views on philosophical, political or religious ideas. If my copy of a book is in rented storage 'in the cloud', ownership doesn't come with that ability anymore. Even if storage is made dependent on a one time fee, as for a physical purchase, the persons controlling access gain the ability to charge rent to those persons who want all the rights everybody once had (in this case, casual users may not see a difference, but universities and such can be manipulated into paying regular fees for access to verified, un-tampered-with editions or databases).

              Rent-seeking frequently involves lieing, for example by arguing that ownership never meant you could do absolutely anything you wanted with property, so a publicly ratified speed limit is equivalent to a private lease contract where you agree to let the carmaker give your personal payment data to all insurance companies and receive fees from them. It also involves special privilege (in the most literal meaning of that word, private law) in legislation - for example, the laws in most US states which state there is a contract attached to purchase of a movie theater ticket, even though the patrons don''t see or sign that contract. Such associated methodologies are often an indication that the goal is not merlely to offer something for rent voluntarily, but to coerce.

What reasonable people here are debating is whether the current standard rules are enough or if we should adjust them further to 'err on the side of caution'. Personally, I would go with more caution by the CDC, AND more caution by the airline, but carry that far enough, and we take a flamethrower to a perfectly good airplane.

If America does end up with Tens of Thousands dead, it will be because of people who are so political that they want immediate reprisals against people of the other party they think may have made mistakes that may contribute to deaths in the future, but no action taken when we already have at least one actual death and clear indications of actual negligence, unless there's political capital to be made and it doesn't step on anyone in their own party's toes.

When I and the ex got divorced, we got one really good lawyer for both of us, and split the cost. He helped keep things amicable, and didn't charge a lot because we didn't create a lot of work, but it was still only borderline worth it. The kids were already grown, and we ended up getting back together in a few months although we still haven't bothered to remarry, so a lot of what the lawyer's fees bought us was intangibles, such as having the hearing privately in the judge's chambers instead of in open court. Those things matter more to some people than others.
        There were some legal issues we might not have thought of on our own, like reworking some power of attorney forms for things like taking our nieces or nephews to hospitals for emergency admission when either of us was baby-sitting, or making sure the state knew what to do about her last name. (A good lawyer in such a case should be able to tell you if your state usually screws something up - mine at the time, usually automatically decreed that the female partner now was known by her maiden name again, and filed appropriate forms with about half the state agencys and no federal agencies to get it 'corrected', on roughly half the female partner's personal records, if you just used internet standard forms and filed it yourselves - OTOH in an acrimonious case, lawyers have been known to file forms to get the other person added to the no-fly lists under false pretenses and similar dirty tricks, so doing it yourself may be better for everyone than picking a lawyer that fights dirtier than you want him to. I recommend a lawyer who's good in both senses - competent and ethical.).
          I hate to say it, but if the two parties are in a situation such as one of them having a security clearance, or a foreign bank account, or a special needs child, or many, many other circumstances, the couple should talk to a lawyer even if they don't get separate representation - that's because most states have at least a few really badly implemented or archaic laws on the books, which will turn out to bite one or both of you on the ass about a year after you thought the divorce was final. I am not a lawyer, but I am a tax professional, and I have seen IRS audits where the agents involved seemed to regard the couple filing for divorce without a lawyer as Ipso-Facto proof of intent to evade on some failure to pay taxes on foreign account cases. I have even heard of a case where the couple resisted both attending the audit together, only to be compelled to go through the audit with armed agents present. The IRS claimed to simply have interpreted the pair's reluctance as possible fear of the other partner and so provided security on their behalf. That may have been the case, but it does sound rather intimidating, and the claim that they were doing it because of concerns expressed by the clients would probably mean there was no effective way to object.

            In fact, one prominent researcher said of these studies, he was now of the opiniion that it was not possible to phrase whatever was really happening in a natural language, and he could not offer a theory that fit all the facts without it sounding like "Four-sided, colorless, green triangles meditate furiously.

The point is, you can define "liberal" to the stage where Reagan, Nixon, and even Goldwater were 'liberals", just as Fox news insists that ALL the other media outlets are liberal.
Remember the tax rebates of 2008 and 2009? It's estimated that individual consumer spending drives about 68-70% of all economic investment in the USA - in fact, the 2014 estimate for that is exactly 70.0%. Just about everyone in economic circles accepts this number, maybe with a few minor quibbles. That means a neutral (not conservative, not liberal, not supply side, not demand driven tax rebate would have been about 70% to individual consumers). Both the Bush and Obama year tax rebates were about 32-33% individual consumer and 68-67% business breaks, ergo, the "liberal" Obama tax rebate was weighted about 2 to 1 towards the ultra conservative end of supply side economics. Here's one of very few areas where there is a clear, unbiased, objective definition of where the line between left and right is, and by that test, the Obama administration is extremely conservative, as is damned near everybody elected these days.
        As much as I like treating the whole left v. right model as terribly over-simplified and using at least a dual axis model, and as much as I can respect your arguement about autoritarianism, the position that Eisenhower looks like a (modern) Democrat is simply factual. The Republicans may have shifted more towards an interventionist model in foreign affairs, or supported big government spending more than they once did, but that's not the biggest change - the Republicans haven't failed by drifting towards the Democrats on a few key issues, and only need to reform themselves merely by getting back to their "small government" roots. The real difference is between a party that is now 99% for whatever the MIC stakeholders want and a party that is only about 55% for the same thing. Until there are Republicans who want to cut MIC related spending and not just "social" spending to reign in big government, there is no meaningful distinction between a fiscal conservative and a neocon or a tea-partyist. Hell, until the Republicans get a single candidate that even admits the objective fact that cutting ALL of what they themselves define as social spending includes cutting the VA budget too, the idea of a populist Republican remains an oxymoron on the level of Nice, Sweet, Wholesome, Axe-wielding, Coked-up, Nazi, Mansonite Xenomorph. Not that I'm saying Republicans are monsters, just that their policies nowdays have contradictions that are ultimately at the very far ends of ANY normal or same spectrum, and leave them saying things that are literally impossibly self contradictory with every position they take.

What's an ideal IQ? 200? 500? The scale is open ended at the top, and even a perfect score on different tests equates to a different maximum.

  Plus, I'm pretty sure that your "less than ideal" would apply to some of the most brilliant people in history (James Clerk Maxwell, estimated IQ 115 (note that people who achieved something that applied to practical discipline, such as engineering or medicine, seldom did it nearly as early as precocious musicians and novelists, and so are always estimated lower unless the estimater includes a fudge factor. Mozart gets estimated much higher than Beethoven without that, because he started at 6, not 22. The way the fudge factor is calculated is to simply set both those great musicians to an (apparently arbitrary) 165, and adjust for age of first composition based on that ratio in calculating other historic musicians scores - this makes Wagner among the very elite, and Bach only 'fair to middlin').
          Or try Charles Darwin, and Copernicus, both estimated IQ 160, (The same score, as Dolph Lungren's actual test results). President Bush (41) scored a 98 - his son Bush (43) scored 125. Steven Hawking scored "only" 160, same as the estimated score for Einstein - both are eclipsed by actor James Woods and John Sunnunu (180 actual score each)
          President Carter scored at least 10 points above any other president or presidential candidate of the 20th or early 21st centuries, and of the current crop, Hillary Clinton is 5 points lower than Carter, but still beats everybody else that has shown any interest in running this time by at least anoher 10 points.

Einstein used to claim that average people were much closer to being geniuses than they had been trained to believe.

"I am neither especially clever nor especially gifted. I am only very, very curious." - Albert Einstein

Your "Hard work, imagination, creativity..." (and curiosity, as in the quote above), were all things Einstein thought could be cultivated by anyone who wanted to be wiser or smarter, and would let anyone create the sort of ideas he was famous for creating.

On imagination, he said "Imagination is more important than knowledge." - Albert Einstein

Yet, he also praised even the lsss disciplined forms of imagination:

"The gift of fantasy has meant more to me than my talent or absorbing positive knowledge." - Albert Einstein

Given that he thought many people were capable of genius far beyond what they actually did, he may well have believed that taking some risks, such as drugs, could have positive outcomes in freeing up that genius. It's not like Einstein was still around when most of the psychoactives became famous/infamous, so I wouldn't care to bet money he would have been either ardently anit-drug or pro-drug in that respect, but I suspect he would have thought the people considering drugs as paths to understanding the universe at least deserved credit for wanting to understand the universe, instead of taking the drugs common in his day, which seemed to promise mostly mindless obliteration (alcohol and the opiates and barbiturates).

The idea that we could screw Earth up enough that it would be easier to terraform Mars or something should be very disturbing and frightening to us, a strong motivator to fix what we are doing wrong right here instead of cut and run.
            As we discover new things we can do in physics, learn to hack our own biology and how Earth's ecology works, as we get more data on whether there are Earth-like planets in other systems, maybe find evidence of life on other worlds, we are going to actually know something about how hard it is to change ourselves for space, how hard to change other worlds to suit us, and what environments can support life of what kinds. I suspect there will be moments when we learn some things and say "Aha!, Now we know how to succeed at doing X, and why we shouldn't waste lives and resources on Y.", but we need a lot more such moments first. I'm willing to bet that learning more, fixing things right here, and maturing as a species will lead to a time when there will be obvious reasons for a stable, long term human presence in space. I even suspect we can make this world the sort of place that other space faring species, organic or machine, might want to have for a neighbor.
            Cleaning up our own act here may one day make human expansion in space possible - deciding 'here is too hard, but out there will be easier' is the perspective of madmen.

Recrafting our educational system so our best and brightest don't spend the first third of their lives just getting through school is something that we need for here and now, even if it may also give us explorers who are skilled enough to survive while still young enough to live through even lengthier missions. Stabilizing this world's climate is something we need here and now, even if we may one day use that knoweldge to warm Mars. Yes, there are things we won't learn until we try space, but those things are built on a foundation of things we need to know for right here and now, and we need that foundation built first or we can learn nothing by going into space.

Yes, the mortality among the infected was lower than ebola is now, but we literally don't know how big a difference that may make from what will probably be much less than 20% infected but with 50% or possibly higher mortality. Right now, I wouldn't say much lower chance. Overall, even if ebola somehow completely overloads modern medicine in first world countries, the results in a worst case scenario would in fact be pretty similar to the 1918 flu, just fewer actually getting it but with a higher chance of dieing if they do, and similar overall numbers. By the way, the 1918 was determined to be an H1N1 variant, so people might want to get flu shots any year that's one of the three types they combine for that year's shot, even if they don't get them otherwise.

Lethality in the 1918 Flu most often resulted from triggering an extreme immune response, where the person has a chance of running an extreme fever that destroys nervous tissue, or drowning in their own lung secretions. Initial description of cause of death was often "shock". This happens most in young, healthy people with great immune systems that can overrespond. The other group most hit had poor immune systems and died mostly with non-shock related symptoms, for example, many TB patients succumbed to the flu. My grandmother was a nurse during the 1918 epidemic, and used to tell me about how surprised people were to see young healthy patients, doctors and nurses go from asymptomatic to dead within a single day. She herself had only a mild case with essentially normal Flu symptoms - by the time she was feeling rotten, most of the people who died on her ward were already three days dead, and the word was getting out that for otherwise healthy, young people, the more sudden the onset, the more likely it was to be serious, but it was years after the epidemic that people really noticed the two distinct at risk populations as a pattern, and decades later that the phrase 'cytokyne storm' was first used to describe the immune system overload.
