  1. Re:Linux News... on Preview Of Linux 2.5 · · Score: 1

    Eh? You don't HAVE to download the newest kernel. There ARE individuals who LIKE to download the latest and greatest and play with it and they are invaluable as aiding in the debugging effort. Sure, linux could go all cloistered and slow like *BSD and only release the occassional new update, but then, this is slow precisely because there aren't thousands of users helping find the bugs.

    The BSD system works for a slow-developing system but it really isn't keeping up with the fast pace of hardware development the way linux is. Someone buys a brandnew video card, wants to take advantage of it. Will they stand a better chance of that with linux or *BSD in the near future? They will with linux because within a couple weeks, a new kernel with support for that card will be released and those early adopters get to make use of their new hardware NOW as opposed to months from now.

    I've been contemplating playing with FreeBSD for a while, if for no other reason than to gain experience with yet another unix-like system. For most of what I do, I imagine it would be fine (lyx, web, email, learning a wee bit of programming) but there is one thing I doubt as far as *BSDs capabilities: GAMES.

    I have several loki games and I run several other windoze games under wine. I recently got DRI hardware 3d accel working (REAL nice) with my ATI Radeon card and it works well with the games. Can *BSD handle any of this? I assume the XFree/DRI thing is not a problem (is it?) but what about actually running the games?

    If I can't run my games on it as well as I can thus far on linux, then it is ultimately a non-contender. Also, can one run StarOffice on it? Sure, sure, you can complain about this or that aspect of StarOffice but it DOES do the job nearly as well as Office on windoze does, to a greater extent than ANY other available linux suite. If it (staroffice) could do citations/references like lyx can then I would use it exclusively but... Can *BSD run StarOffice?

  4. Not a "fountain of life" or youth for that matter on "Cell Executioner" Gene · · Score: 1

    There are MANY genes involved in the process of apoptosis. The deactivation or mutation of several of which are required for cancer. A cell that starts dividing like crazy, regardless of DNA damage or cell-cell signals is normally stopped cold and self-destructed via apoptotic genes. When a cell loses that function, it is well on its way to being cancerous.

    Longevity is not simply some apoptotic barrier, it is due to many factors, much of which is tied to DNA damage. You DON'T want you damaged-DNA-containing cells to keep reproducing in order to keep you young. The cost of your extended youth would be many abnormal tissues, malignant and non-malignant tumors, etc. Simply stopping apoptosis isn't going to make you forever young, it simply would be accomplishing some of the initial required steps for cancer development.

    What you really need is improved/more DNA protective machinery (free radical scavangers) and repair machinery coupled, telomere length maintenance, and STRONG apoptotic mechanisms to catch the damaged cells that get past the repair machinery. THEN you get longevity without the abnormal growth of cells that shouldn't be permitted to continue.

  6. Re:Thinly-veiled anti-cloning propaganda on Cloned Animals Show Grave Health Problems · · Score: 1

    Ah, simple and seemingly logical argument but flawed. The truth is that sperm are produced all the time by the billions in a man and that requires constant, non-stop cell divisions. The cells that make sperm are not younger than the body making those sperm.

    Something similar occurs for the egg though not to the same extent since the eggs are already pre-made, so to speak, by the time a female is born. What has yet to happen is maturation of the set number of eggs. They are dormant, for the most part, and they form early and so are not subject to as many cell divisions as spermatagonia but they are not young cells either.

    My personal theory is related to your general idea... The vast bulk of DNA repair enzymes are tied to transcription (or tightly associated with transcription). What THIS means is that each of your cells saves time and energy repairing the DNA that it uses - DNA that is actively transcribed into RNA - and for the most part ignores DNA that is not transcribed. In all cells except neurons, MOST genes are turned off and not transcribed and so are not a primary target for repair. Neurons, on the other hand, are the one cell type that has the most DNA being actively transcribed all the time. Thus, neurons have more of the cellular DNA subject to repair than any other cell.

    What you COULD try to do is use glia DNA or neuronal DNA as a source for cloning, hoping that 1) a lot more of that DNA is open for business normally, so to speak, is therefore subject to constant surveillance and repair, and 2) a lot more of neuronal DNA is not silenced relative to other cell-types, and therefore not in need of turning on in the egg. Less chance for the hypothesized errors.

    Another source for DNA for cloning would be adult stem cells that must retain the ability to become one of a range of cell-types at any time and, therefore, much of their DNA is also not likely to be heavily modified for silencing vs fully differentiated cells.

  7. Re:what about the already born human clones? on Cloned Animals Show Grave Health Problems · · Score: 1

    There ARE human clones. They are called "identical twins". They are more identical to each other than any laboratory clone could be to the DNA donor for it.

    You could do the same thing - clone people into identical twins - by borrowing the normal way it happens. You let an embryo develop to around the 16 cell stage or so, split it into two 8 cell embryos, implant them and viola! You just cloned someone. Really cool would be to do it twice and create the first identical quadruplets. All clones.

    Sure, it isn't as unusual as an adult with a (near) identical twin who is many years younger (a classic clone) but it IS cloning to perfection, so to speak.

    I will certainly consider it but I think I will still give a few other things a shot first to make sure that the "problems" I sometimes have are real vs due to lack of lyx knowledge.

    For instance, I have a paper ready for submission but my thesis advisor has to review it first. He complains that the font used (by default) in lyx for the abstract is too small. I cannot seem to change this font...as if lyx is set to use one font size and ONLY one font size for an abstract style. Other issues have to do with formatting that, so far, I can only seem to clear up by learning latex commands, which I would rather avoid whenever possible.

    I certainly DID mention what I use. I use lyx plus pybliographic. This suffices for the most part but lyx isn't quite as "friendly" as many wordprocessors are and there are some quirks that drive me nuts.

    In spite of the fact that most of the sci-journals I submit to do not accept Word documents, I have to ultimately open my lyx docs in Word to save them as word documents for in-house use. Lyx and latex just don't do doc. At least, with a number of the word processors, there is an ability to save docs in Word format- and if they had the reference/citation ability I mention, they would be near perfect for use.

    I stand by what I wrote. You CANNOT write research papers (in school/college/work) or any kind of scientific article without citing references. A hell of a lot of people have to write papers in school, no? A lot of people, from CS to physicists to biologists to doctors HAVE to cite references in any official papers of any importance. You simply cannot do this properly with word processors that require you to add reference pages and citations by hand as an afterthought.

    Mundane writing is fine but it is ONLY thing that ALL available wordprocessors do with near equal ability. You can do this with a simple text editor. What not a single wordprocessor in linux can do is what each of the MAJOR wordprocessors in the windoze and mac worlds CAN do (via an additional software package like EndNote)...handle references/citations/bibliographies. To do this, the wordprocessors have to be friendly to the addon app. NONE of the linux wordprocessors are like this. Not a single one even considers the possibility that people may actually need to cite references - hence they (the developers) expect all writing to be based on nothing. Heresay. They obviously don't recall college or primary school in which they HAD to cite references. They obviously have simple jobs that do not require extensive research to back up what they state/write. If they did, they would realize that you MUST cite references or your words are no better than the bark of a neighbor's dog. Mere noise.

    I am tired of recommending to these developers that they would actually have something different from EVERYONE else if they made their package friendly to not only the casual writer, but also the professional who makes proper attributes in their writing.

  12. There are no serious linux wordprocessors on Interview with Dominic Lachowicz of Abiword · · Score: 1

    THERE IS NOT A SINGLE LINUX WORDPROCESSOR THAT IS A SERIOUS WORDPROCESSOR. A REAL and serious wordprocessor would support references/citations in some way. In the Windoze and Mac world, Word or Wordperfect have EndNote to handle citations and generation of bibliography pages. In linux the ONLY apps that can do this are latex plus bibtex or lyx plus pybliographic or sixpack.

    It is impossible to write serious research papers or professional scientific papers without a bibliography/citation capability of some type. It is unacceptable to have to create a reference page or pages by hand and then enter your citations throughout your paper by hand. With lyx, which is not properly a "wordprocessor", this is trivial and easy via pybliographic or sixpack (or you can do it semi-automatically within lyx as long as you know the index names of all your citations).

    What is needed is for SOME linux wordprocessor to actually include this functionality within itself, along the lines of a built-in EndNote or pybliographic or sixpack OR it needs to include a pipe that can be utilized by pybliographic or sixpack for interfunctionality. Pybliographic and sixpack use the lyxpipe to place citations into your lyx document. In lyx, you enter the bibliography name at the end by adding a reference section. When you print it, it automatically handles the citation formatting as well as the formatting of the reference page(s)...just like working with Word or Wordperfect on doze or the Mac with EndNote.

    I have requested/suggested this functionality to everyone who is working on wordprocessors (koffice, Sun with staroffice, abiword, etc) but it never comes to anything. No scientist or serious researcher can make any use of the weak wordprocessors available to linux without this functionality. That leaves serious writers with lyx or latex, period.

    If you want to write letters to mommy and daddy, or a letter to the editor at your local newspaper, then Abiword, kword, staroffice, etc, are fine. If you do SERIOUS writing: research, scientific publishing, etc, then they are pathetic toys of no use - merely glorified text editors.

Analyze the florescence on the DNA chip vs your test DNA or RNA and you know its information content - no destruction necessary.
