    One of the points of classical Capitalist Econ 101 is that, if a particular sector of industry consistently makes more than the average profits of business as a whole, tremendous, inexorable, possibly literally transhuman forces, (sometimes called the invisible hand) will push it back into line with the rest of the economy.

    When a sector is making a 20% profit against an average for businesses of only about 3.4%, then classic Capitalism would say the forces trying to steer that sector back into line with the rest are about like a bunch of Mind Reading Giant Anime Robots, piloted by D&D 23rd level wizards and led by the Archangel Gabriel, doublewielding Nuclear Powered Uzis and riding the love child of Samatha Stephens and Hellboy.*

              Which makes it really bizarre to see people defending the sector's record profits as though they believe fervently in this free market/invisible hand stuff, but think the problem can be solved by debating with those people on Slashdot who 'just don't understand'. Yeah, shooting straw wrappers at him will stop Godzilla, too.

In countres where it is still trademarked, the word should be written with a capital A, as Aspirin, the way you used it. The correct way to write the trademarked Johnson and Johnson wound care product is Band-Aid, with the dash.

    But surely, even if some of the ACs above are a bit confused, that's not because someone still spends money on marketing brand names like 'Band-Aids". Surely they don't spend anything much on them, Let's see, for 2012, Johnson and Johnson claimed consumer wound care products resulted in sales of about 1 Billion US dollars, even, out of about 67 billion totak. Total advertising was 2.3 billion, so if we assume consumer wound care doesn't get a disproportionate share, that's 'only' approximately 34 million dollars a year. I don't think I'd call that next to zero.

You make it sound like non-Christians doing this sort of charity actually feel goodwill, and the Christians don't, but do it for fear of punishment or displeasing an arbitrary source of commands.

    "twelve of the 186 people tested had serological evidence of infection with EBO-R. 22% of the workers at Ferlite Farms had positive IFAT (indirect fluorescent antibody test) titers, which was significantly higher than at the other three export facilities."
                  Those infection mumbers are low for a virus that normally attacks humans, like Ebola Marburg, in a setting with no precautions at all and lots of hosts, but the fact that humans have no significant symptoms from it says that the Reston variant virus does not colonize humans at all well, and so are at least marginal support for it being exceptionally likely to survive in the environment, compared to the more human lethal types. This just might indicate that Reston is airborne, but probably just indicates it survives a bit longer on surfaces or takes a little more exposure to some disinfectants to destroy than the commoner Ebola virus types. So you're halfway right about that - Reston is not presumed to have become air vectorable, it's just been raised as a possibility in discussion, and is still rated as less likely than some alternatives.

    this particular shipment of nonhuman primates had a far larger number of deaths in Room F than would normally have been expected.

    I see a bigger problem with Google acting as unpaid law enforcement. It puts their own employees at risk. Criminals, particularly the sort we are now calling terrorists, will not see any sharp line between a company that acts to aid law enforcement, especially without even needing a subpoena, and the government itself, and the one big distinction they will see is that the company does not have heavily trained, firearms wielding personnel in large numbers.
              It's only a matter of time before somebody attacks one of these companies and issues a statement that it was a blow against the hated government. A smart company realizes that a court order gives them plausible deniability when they are accused of starting a criminal investigation or being over zealous in making accusations. They can say they were only doing what the law required, and the investigation was already ongoing, neither of which makes any sense as an excuse if they become extremely and seriously proactive. A smart company realizes that making their typical employees into soft targets is not fair to the employees.
              More simply, if you are an employee, and your company is asking you to do things that may leave a criminal wanting revenge against you, or a whole group of political nutcases targeting you, do you get the pay, equipment and training of an FBI agent or US Marshall? Does your workplace have the security of a federal office building? Does your health insurance have the same clauses a cops or soldiers does? Do you get paid to stay in shape on employer time in case your environment becomes a combat zone? Would the company use its legal department to protect you if the criminal sues you? Even if your management and you both really want to help catch the criminal, do they mean it enough they will back you up for your part, if that criminal is now carrying a grudge against you? Could you even expect your company to keep track of when a guy like this gets out of prison and warn you, or send a lawyer to his parole hearing?

It's easy to feel good about helping catch a particularly scummy criminal such as a pedophile, and harder to allocate the resources to properly protect your people from that potential blowback.

    Does sexual selection actually work at all? Less controversially, does it accomplish anything regular natural selection can't, or is is an explanation that is simply redundant to natural selection as a whole?
              For example, there are some species, such as Walruses, where there are extreme differences between males and females, and we use Sexual Selection to explain how those evolved. The problem with that is revealed by Bighorn Sheep, among various other species. There, we have both a lot of dimorphism, and males acting very competitively in displaying themselves for the female, but it turns out that the famales aren't 'selecting right'. Female Bighorns seem to go off with the loser as often as the winner, or sometimes take up with a mate who isn't engaging in the head butting displays at all. Unlike Walruses, the males don't seem to have any way to keep females in a harem unless they can be convinced voluntarily, and since all a sheep has to do to signal unwillingness to mate is stop standing perfectly still, opting out seems to be the female's choice. Most recent studies either show no real pressure at all or a rather mild form of selectivity that doesn't seem like it's enough to explain major size and feature difference unless they could also be explained by non-sexual selection pressures. In other words, winning at head butting doesn't really seem to increase a male's chance of mating, so it's now unclear both why males butt heads, AND whether there as been any sex-based selection, at least in sheep, to cause the behavior.
                Something like this also shows up in African lions, where the male's size and mane can probably be explained by them being the part of the tribe that fights off Hyenas and Baboons just as well as sex based selection.

The effects were milder than typical chemos, I'd say much milder - After getting through the first two weeks when the IVs were daily, she went to once a week, and had only ntermittent nausea on the day she actually took the IV drip, usually controlled with just oral Dramamine, and she was usually able to eat within a few hours of leaving the clinic, The first two weeks took simultaniously administering IV painkillers, anti-nausea and anti-fever drugs, and she still felt like a bad case of the flu, but after that 2 weeks the dose came down form literally billions of internal units to just millions, and it got pretty tolerable. Sometimes she still felt lousy the next morning, but usually she was feeling fine by 2 or 3 hours later. Pain management became Tylenol. This whole treatment may have made her Arthritus start up earlier, but it probably had no effect there and she likely would have developed RA just the same. Bad effects like joint pain, high fevers, and just possibly even memory loss are known with these tremendous doses, but they all have very low chances, i.e. less than 1% of patients, and without getting at least one of those, most patients wouldn't say they hated it. It's not like the endless weeks of nausea, extreme fategue and pain that's pretty damned common for regular chemo.She made friends with a dozen people on conventional chemo at the same oncologist's and she and the other interferon patients frequently discussed what troopers those people were and how much easier the Interferon group had it.
              Conventional chemo is not usually as effective in advanced Melanomas, as these really, really massive doses of Interferon, and it certainly worked in her case, or one of the odder experimental things we also tried did, because she beat literally billion to one odds with an initial tumor over twice the diameter that typically gets classified as stage 4. Her oncologist said the first 6 months on Interferon had probably done everything Interferon would do, but If it wasn't too bad, she might improve her odds a little more by sticking with it a full year, and she had no hesitation staying on it. Upwards of 65% of people who are treated this way manage to stay on Interferon IVs for the whole year, and the biggest reason to stop earlier seems to be if the person has bad veins and the clinic is worried about damaging the circularory system further when they may need to try other treatments.

Online bullys don't usually just make speech involving insults and putdowns. There's a high degree of these being accompanied by false accusations that can easily count as libel, and by misinformation which is often damaging in other ways. (In fact, for cases where bullying goes on for over 3 months, the chance of one or more of these other actions approaches unity). We've seen cases where, for example, the bully has progressed to claiming that a victim is HIV+, and then giving out a lot of misinformation about HIV in general, falsely claiming to be a doctor or to have gotten the information from one, an/or claiming to having hacked their victim's medical information. These things are generally criminal in and of themselves, and/or have other negative impacts (such as triggering security audits of medical records keeping to make sure the bully's claim isn't genuine), Protecting teens against insults and put downs is a mixed bag, but when you add in protecting them from bad medical and legal advice, and false claims that they can't protect their records if they see a doctor, and so many other things, any sane society is going to opt for some limitations, at least with regard to minors.
              This form of bullying has many interrelated bad effects: Laws get passed, because existing laws don't seem to be stopping the problem behavior.

Even if a politician actually cares about free speech (I know, I know, but some of them actually do.). The ones that actually try to live up to the Constitution, the UN declaration of rights, or other such inspirational ideas are also the ones who really want to stop these other related abuses, so even they will look to compromise (and for the ones who are just pandering to whatever group will get them elected, that sort of compromise is a no-brainer). Let a creep get away with enough, and everybody wants to see some sort of blowback, and if it looks like that creep is just hiding behind a first amendment claim, then the first amendment starts to be called a "technicality".It takes more character than most have to defend Vlad Adolph McKnife-wielding-Psycho. That's why there are phrases such as "Online Stalker" - behavior analogous to real world stalking, not just insults.

Tolkien was supposedly torn between finishing up the Silmarillion or going back and working on a 'better' hobbit first. I suspect there's some truth to this claim - LotR draws from a great many sources that are fundamental in studying early English literature, from Spencer's Faerie Queen to the "Jack the Giant Killer" stories, to the Song of Roland to Beowulf itself, and the Hobbit's literary roots are mostly in one story - the same one Wagner drew on for Das Rheingold. Some of the dwarf naming and such in the Hobbit seems to connect to Finnish mythological tales and maybe some other Scandinavian sources, but the references are mostly truncated there or limited to a few very short phrases to fit in a children's book.
              I can certainly see JRRT deciding to work in some other bits from classics he couldn't really use in LotR. LotR took so long because Tolkien wanted it to have a certain gravitas as fantasy and so aimed for being really encyclopedic in referring to the roots of Fantasy literature, and at least touching broadly on English literature of the mundane and modern kinds. Tolkien even read some Lovecraft (and liked it), probably before writing the scene of the Watcher at the gate to Moria, possibly afterwards to see how it compared, and read or re-read some of the more esoteric works of T. S. Elliot, R L Stevenson and such, maybe just to have a better idea of where he wanted to steer modern English lit. or maybe to see if he needed to actually address these modern works in what he aimed to make his Magnum Opus. What he did afterwards, planning a next stage after becoming such a success, was doubtless quite technically ambitious.
            I respect people saying they don't like this or that, but some of those people might want to do a little research before they label everything they don't like as not true to Tolkien. In particular, the scenes where the dwarves try to use all the gold to kill the dragon seems to have some real connection to Tolkien's plans for the story, and possibly the way there is more about human 'politics' in Laketown is too. Once people get some idea of what might have been the Hobbit, rewritten for an audience the same age as LotR's, they can rag on the Hobbit equivalents of Elven Shield Surfing twice as hard. (Please!

(Note that we are talking about their light ouput raising the planet's temperature, not them gravitationally nudgeing the planet about - gravity and how stable the planet's orbit can be if the orbits of the suns themselves are changing, that's a seperate question) Fictional Kalgash would have to orbit the biggest sun of the group and it would have to count as being near the cooler edge of the life bearing zone before you figure in the other stars, but even before the lesser suns temporarily shift into a quasi-stable configuration that prevents night from occuring except once every several thousand years or whatever, there would be various configurations that would make night a very short lived or rare and irregular thing, and life would be used to that. There are other issues, such as how do plants dispose of waste products on Nightfall world, but those issues don't vary much if there's a short night every few months or only in a thousand years - plants would have to adapt for situations much less prolonged than the current one. If we call the Nightfall orbits "perfect", then even very imperfect multi-star systems would find life constantly facing this problem.I'm thinking that by your argument, it's all too easy to say things such as "Life in Binary systems? Impossible!," and even "Life when the day lasts more than 24 hours 17 minutes? Absurd!", and things like that. I'll refrain from quiting Jeff Goldblum at this point, but hope you will consider this.
            Then there's the question of how sensitive to light the natives eyes are. If nights have always been at least short and irregular for much longer than the perfect situation has existed, we should expect the natives to not have very good night vision, as there's less demand to evolve it, so talking about relative optical wavelength outputs and such is very hard to do meaningfully.I'm not sure how we could criticise the work as SF on that basis.

    Oooops! I would drop an 's' from assess and make it asses. Why just mispell something when you can make what someone will probably call a Freudian slip, after all? Please excuse me.
