  1. Re:The Internet, where else? on How Do You Keep Up With Science Developments? · · Score: 1

    Due to the corporate mentality of I.P. and the subsequent patent/copyright laws that go with it, not everything is on the internet. The medical field for example has multiple white papers, theories, and discoveries hidden behind a wall of corporate "foundations" that require $$ to gain access to.

    So how is this anything new? I remember a few decades ago, when I was a grad student, trying to get at the latest research in several fields. I was effectively blocked at the source by the subscription prices of the relevant journals, which together cost much more than my income allowed. But there were the academic libraries, right? Well, not necessarily. Unless you passed the relevant tests, you were often not allowed access to those inner sanctums, and couldn't read their copies of the journals. Academic libraries routinely restricted access to their own department's students.

    This has always been especially true in medical fields. For example, in the 1980s my (future) wife was a grad student at Harvard and BU in economics, with a specialty in medical information. At both universities, she found that her access to the medical libraries was seriously restricted. She wasn't a medical student, after all, and econ students clearly had no "need to know" actual medical information. Even when she managed to get access, doing so often required far more time than the actual reading, and often required the repeated intercession of her profs.

    The Internet has opened things up a bit, but we still have a long way to go before a lot of important information is available to someone without the major amounts of money needed to get past the checkpoints.

But, for example, drug manufacturers don't usually like to hear that their profitable "miracle drug" actually has no effect on the conditions that they claim it will cure. Admitting this publicly means they'll no longer get income from the suckers who have been buying the "drug" to cure their condition.

This means that after a few days of perp walks with various FBI and politicians patting themselves on the back, they'll drop the show and move on to other things.

    Any group goes extinct eventually. The evolutionary question is whether their descendants died out. The Cro Magnon and Neanderthals both have millions of descendants today, so neither is truly extinct.

    We can expect that further research will clarify the fraction of their DNA that both contributed to the modern population. Of course, as any geneticist will agree, both were over 99% identical genetically to the modern population. The differences between human subspecies are very small, and mostly superficial.

    The question of percent contribution of genes is really talking about a tiny portion of the human genome. And the result was almost certainly the usual result of population mixture: Each population contributed a collection of mutations, many of them adaptive and beneficial. A few hundred generations weeded out the inferior variants, leaving a somewhat better-adapted population than before. And the process continues today.

    Now it's "if you aren't 100% African, you're part Neanderthal."

    Can someone please explain how. I mean they are both homos right?

    Nah, homos usually don't produce very many offspring; it's the Homos that do that. ;-)

    Typographical jokes aside, the explanation is fairly straightforward. Both this paper and the one from a few months back included DNA from some widely-separated non-African populations, including such isolated areas as New Guinea. They also used data from the past few years' analyses of fossil Neanderthal DNA. They've produced a list of gene variants (mutations) that were found in Neanderthal and non-African modern DNA, but aren't found in any (tested) African populations.

    It's possible, of course, that the same mutation will appear in different populations. It's also possible that a gene variant will die out in all populations. But as the numbers increase, the probability of what's been found in these various Homo populations rapidly approaches zero. For Homo sapiens and H. Neanderthalensis to be still classified as separate species requires many cases of either an independent identical mutation, or a gene variant shared by all our ancestors that died out in all the African populations but survived in all non-African species and also in at least a few Neanderthal populations.

    The probability is now so low that nobody sensible would seriously consider it. The Neanderthals are now firmly in the Homo sapiens species.

    There will, of course, be further independent tests of this reclassification. Challenging such "accepted" things as facts is a popular game among scientists. DNA research continues, especially in humans and our close relatives, and we can expect many more tests of our Neanderthal ancestry to appear as spinoffs of other research. But unless someone comes up with firm evidence to the contrary, anyone with non-African ancestry should now assume that they're part Neanderthal. The most likely outcome of further tests is detailed information making the history clearer.

    We can expect at least a little bit of fun about this coming from comedians of African ancestry. Of course, most American blacks also have European ancestry, so they're part Neanderthal, too. But we can hope this won't discourage them from making lots of jokes about it.

    It was strongly suspected, but not known.

    Yup. The previous study, by Svante PÃÃbo and friends, was statistical in nature. They showed a significant probability that a collection of gene variants that are found in several tested non-African populations, but not in any of the tested African populations, are of Neandert(h)al origin.

    This one seems to be more definitive (though I haven't seen any numbers on the sizes of their test populations). It's about a gene variant that was already known to exist in "all" (whatever that means ;-) non-African human populations, but not in any (tested) African population. It was considered to have originated in an unknown archaic human population. The gene variant turns out to be in the recently-published Neandertal genome. So it almost certainly originated in either the Neandertal or the non-African human population, and spread to the other by interbreeding. The researchers point out that their study didn't involve any work with Neandertal remains, so there's no chance of contamination of samples.

    There is, of course, a slight possibility that the same mutation could appear in two populations independently. But the probability of this is so low that it can be safely dismissed.

    The mutation could have also been from a common ancestor to H. sapiens and H. neanderthalensis, and died out in all African populations, but the chance of that is also miniscule. The geneticists have been telling us for some time that most human genetic variation is within Africa, with the non-African populations being a minor branch that colonized the rest of the world. For a gene variant to die out in all the African branches, but not the single branch that colonized Eurasia and the America (and Polynesia), is simply so improbable as to be dismissed out of hand.

    So now we'll have to revise all the textbooks to replace "Homo neanderthalensis" with "Homo sapiens neanderthalensis". But it shouldn't be any harder than it was to modify the textbooks to no longer list Pluto as a planet. Life can be uncertain for textbook makers. ;-)

Since there was no way to prevent programmers from writing tree-walking code that lacked the obvious loop check, they decided it would be safer to block hard-linking of directories. But, aside from this check, the kernel code was quite capable of hard-linking any file to a new name in any directory.

    Apple's hard-linked Time Machine directories may be a case of the same thing. Since the directories are only created by the TM software itself, and the OSX file system doesn't permit hard-linked directories (for non-superusers?), there's no danger of loops appearing in the TM's directory tree.

She took it back to the Apple store, where they decreed the disk hopeless, and gave her a new one. It had the OS stuff, but not her files, of course, so she plugged in the Time Machine and tried to restore her files. Total failure. After a day or so of getting progressively more frustrated, she took the iMac and the Time Machine back to the store, where it disappeared into their back room for half an hour or so. Then they returned it, saying that it was all loaded. So she took it home, and found that, while her files were loaded, they weren't in the same directory as before, so all sorts of things could find the files.

    I poked around a bit, using a few Terminal windows, and eventually used tar (;-) to restore her files to the original pathnames, after which nearly everything worked right.

    Anyway, I have a Macbook Pro and a couple of linux boxes (that are my "real" internet-facing machines ;-). I back all of them up using rsync to an external disk. This works fine for me. I can (and do) restore any files on it to any of the machines, to the directories where I want them restored (which is sometimes the original directory). But I don't do it with any vendor's proprietary software, I use rsync. Or sometimes tar or cpio. Or "cp -r", though that does break hard links, which I tend to use a lot. They have documentation that I can understand, and it easy to verify that the results are usable.

    In any case, it might feel good to express contempt for "lusers" who can't get backup software to work right. But this doesn't help those users when they need it. There's a widespread estimate that around half the time, backups turn out to be useless, because when you need to use them on the new hardware, they fail. This was our experience with Apple's vaunted Time Machine. Being told we shouldn't be dicking around with it because we'll screw things up doesn't help; it just persuades me that we made a mistake buying the "user friendly" backup system in the first place.
