    Is anyone familiar with The Open Astronomy Journal?

    It seems that Ellis has withdrawn, and is no longer associated with OAJ (source).

    Is anyone familiar with The Open Astronomy Journal?

    While not disagreeing with anything you said, I would like to point out that the Special Issue ("Some Initial Thoughts on Plasma Cosmology") is not, in fact, about plasma cosmology. Well, not the plasma cosmology you were, very likely, referring to (i.e. that of Alfvén). As the Dunning-Davies...

    Is anyone familiar with The Open Astronomy Journal?

    It may well be that 'the inner crackpot' is very common, possibly a trait of the majority, in the sense of wishing/hoping/etc to be the person who finds/invents/presents a radically new idea that is also the next major chapter in mainstream physics textbooks*. This particular OAJ Special...

    Is anyone familiar with The Open Astronomy Journal?

    I found this, which may be (one example of) what you're referring to: OA publisher accepts fake paper You left out the key part of my earlier post, in your quote; namely, "Except for one thing ... (to be continued)" Yes, Special Issue #002, in Volume 4 (2011) - containing four papers, in...

    http://www.benthamscience.com/open/toaaj/EBM.htm is a link to the journal's Editorial Board. Its Editor-in-Chief is Dr. Christian Corda, the Honourable Editor is Dr. George Ellis, and the two Associate Editors are Herman J. Mosquera Cuesta and Lorenzo Iorio. That seems to be a pretty...

    Is sexual reproduction an example of convergent evolution?

    I'd be very interested to continue this discussion in another thread I started, https://www.physicsforums.com/showthread.php?t=414883" In short, the endosymbiosis which resulted in mitochondria is unique in the sense that, as far as we know, the mitochondrial DNA of all present-day eukaryotes...

    Is sexual reproduction an example of convergent evolution?

    And in the general context of my question, viruses are out of scope. Scifi aside ... for meiosis itself, there are lifeforms which handle reduction (and subsequent return to normal) in ploidy in, um, interesting ways (most plants, for example). However, they all fall under the general heading...

    Is sexual reproduction an example of convergent evolution?

    I still think there's considerable confusion over what I'm asking, so here goes one more attempt at clarification. Meiosis is the form of cell reproduction which is at the heart of sexual reproduction; no meiosis, no sexual reproduction*. Possibly with some exceptions (I'm still...

    Is sexual reproduction an example of convergent evolution?

    Thanks everyone for your posts. Perhaps I can clarify my question a bit. While the phylogenetic tree of the eukaryotes is, today, rather uncertain, I think some simple questions can be asked, wrt sexual reproduction. For example, whether there are six super-groups, or more, questions of...

    Bump. 347 reads, zero replies! Anyone?

    Any evidence that some organisms use bases other than A T C & G?

    Thanks Monique. I knew about U in RNA, and that, at a higher level, codon usage does not follow a single, universal, scheme. I'm interested in the fact that, in 3+billion years of evolution, just one basic DNA code (ATCG) seems to be used. It would seem exceedingly unlikely that, had there...

    Eukaryotes - all descended from a single eukaryote?

    Thanks Mkorr. I kinda expected that the answer to the question "was the last common ancestor of all living and extinct eukaryotes (the "first ever eukaryote") itself a eukaryote?" would be "not known, and may never be known", but I thought it was worth asking. I'd read that chloroplasts...

    Do Any Bacteria or Archaea Use Metabolic Pathways Other Than Glycolysis?

    Thanks jim macnamara and zomgwtf. Is there any evidence of convergent evolution, of non-glycolysis pathways?

    Examples of quantum mechanical involvement in biological systems

    Spin chemistry does play a, rather minor, role in some parts of microbiology. For example, the observed relative abundance of various isotopes, in products of various microbiological reactions, is used quite a lot, in fields ranging from geology to studies of pollution. While most isotopic...
