    Subject: A new era for science including genomics ??? Please examine carefully…

    Yesterday, SN , after many years of refusing my similar postings, SN posted my following statement-comment:

    Biorhythms Schmiorythms
    Circadian Schmircadian sleep origin?

    Life sleeps because RNAs genesized, evolved from inanimate nucleotides into self-replicating nucleotides, organisms, of course long before metabolism evolved. They were then active ONLY during sunlight hours. Thus sleep is inherent for RNAs, even though, being ORGANISMS, they later adapted to when/extent sleep times are feasible just as we adapt to jetlag or night work time.

    Since the above two statements are basis for the following statement, may it also soon pass the SN “peer review”… ?!

    USA Science? Re-Comprehend Origins And Essence

    • Higgs Particle? Dark Energy/Matter? Epigenetics? All YOK!
    • Earth-life is just another, self-replicating, mass format.
    • All mass formats follow natural selection, i.e. intake of energy or their energy taken in by other mass formats.
    • Evolution Is The Quantum Mechanics Of Natural Selection.
    • Quantum mechanics are mechanisms, possible or probable or actual mechanisms of natural selection.
    • Life’s Evolution is the quantum mechanics of biology.
    • Every evolution, of all disciplines, is the quantum mechanics of the discipline’s natural selection.

  2. The DNA and RNA genomes are ORGANISMS evolved by life’s primal ORGANISMS, the RNAs, and so are all cells…

    (Extend evolution way down to genes, life’s base ORGANISMS. Culture modifies genetics, not vice versa…)

    Pavlov’s Smile: RNAs Are Earth’s Primal Organisms
    Culture>genes>addiction (2 July 2009)
    http://universe-life.com/2011/09/24/pavlovs-smile/

    Why Pavlov smiled in 2008?

    Pavlov demonstrated effecting placebo phenomena in multi celled organisms by manipulation of their drives-reactions. Now placebo and imagination phenomena are demonstrated also in Earth’s smallest, base organisms, in the genes and genomes of multi-celled organisms, in our primal 1st stratum and 2nd stratum base organisms.
    A very good reason to smile.
    Now an interesting chain is exposed to our view, the Genes-Virtual Reality Chain, a most intriguing cultural evolution chain extending from the genesis of our genes to nowadays, throughout life, a virtual reality existence, and by virtual reality phenomena, exploitations and manipulations.

    PSW1:
    From “Life Genesis From Aromaticity/H-Bonding”
    http://universe-life.com/2011/09/30/earthlife-genesis-from-aromaticityh-bonding/
    Natural selection is E (energy) temporarily constrained in an m (mass) format.
    Natural selection is a universal ubiquitous trait of ALL mass spin formats, inanimate and animate.
    Life began/evolved on Earth with the natural selection of inanimate RNA, then of some RNA nucleotides, then arriving at the ultimate mode of natural selection, self-replication.

    Evolution And Natural Selection
    http://universe-life.com/2011/12/23/evolution-and-natural-selection/

    Natural selection is energy (E) temporarily constrained in a mass (m) format.

    Evolution is the sequence of processes between physical states ordained by natural selection.

    Evolution Is The Quantum Mechanics Of Natural Selection. Period.

  3. Earthlife genesis address:

    EarthLife [email protected]

    A.
    Purines and pyrimidines are two of the building blocks of nucleic acids. Only two purines and three pyrimidines occur widely in nucleic acids.

    B.
    Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring.

    A purine is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Purines, including substituted purines and their tautomers, are the most widely distributed kind of nitrogen-containing heterocycle in nature.

    Aromaticity ( Kekule, Loschmidt, Thiele) is essential also for the Krebs Cycle, for energy production.

    (Wikipedia)

    C.
    Natural selection is E (energy) temporarily constrained in an m (mass) format.

    Natural selection is a universal ubiquitous trait of ALL mass spin formats, inanimate and animate.
    Life began/evolved on Earth with the natural selection of inanimate RNA, then of some RNA nucleotides, then arriving at the ultimate mode of natural selection – self replication of RNAs. ALL Earth life is evolved RNAs. The drive and purpose of EarthLife is to enhance RNAs replication, its natural selection.

    Aromaticity enables good constraining of energy and good propensity to hydrogen bonding. The address of EarthLife Genesis, of phasing from inanimate to animate natural selection, is Aromaticity. Hydrogen Bonding.

  4. Again, Correct Some Figments Of Science Imagination
    http://pulse.yahoo.com/_2SF3CJJM5OU6T27OC4MFQSDYEU/blog/articles/273273?listPage=index&bb=0

    1. Dark energy and matter YOK. Per E=Total[m(1 + D)] all the energy and matter of the universe are accounted for.
    Adopt space-massdistance concept, mass-to-enrgy reconversion.

    2. Higgs Particle YOK. Mass forms below some value of the above D.

    3. Galactic clusters formed by conglomeration?
    Galactic clusters formed by Big-Bang's dispersion, evidenced by their Newtonian behaviour including expansion acceleration.

    4. The universe expansion is fueled by the mass-to-enrgy reconversion. Eventually, as expansion will slow down, will run out of massfuel, gravity will overcome expansion and initiate empansion back to singularity. The universe is a cyclic array of energy-mass dualism, between all-energy and all-mass poles, under omnipresent gravity.

    5. Natural Selection is a trait of organisms, life?
    No. Natural selection is ubiquitous for ALL mass formats, all spin arrays. It derives from the expansion of the universe. All mass formats, regardless of size and type, from black holes to smallest particles, strive to increase their constrained energy in attempt to postpone their own reconversion to energy, to the energy that fuels cosmic expansion.

    6. Life is an enigma?
    Life is just another type of mass array, a self-replicating mass array. Earth life is a replicating RNAs mass. It has always been and still is an RNA world. ALL Earth's organisms are evolved RNAs, evolved for maintaining-enhancing Earth's biosphere, for prolonging RNAs survival.

    7. Cells are Earth-life's primal organisms?
    NO. Earth's life day one was the day on which RNA began replicating. RNAs, genes, are ORGANISMS. And so are their evolved templates, (RNA and DNA) genomes, ORGANISMS, as evidenced by life's chirality and by life's sleep.

    8. Circadian Schmircadian sleep origin?
    Sleep is inherent for life via the RNAs, the primal Earth ORGANISMS originated and originally active only under direct sunlight, in their pre-metabolism genesis era.

    9. Epigenetics are heritable gene functions changes not involving changes in DNA sequence?
    The "heritable or enduring changes" are epiDNAtics, not epigenetics. Alternative splicing is not epigenetics, even if/when not involving alteration of the DNA sequence. Earth life is an RNA world.

    10.Genetics drive biology and culture modifications?
    NO. It is culture that modifies genetics, not genetics that modifies culture. Culture modifies genetics simply via the evolutionary natural selection process of the RNA ORGANISMS. Likewise many natural genetic changes are due to aging and/or circumstantial effects on the genes and/or genomes ORGANISMS, similar to aging and/or evolutionary processes in monocell communities or in multicelled organisms.

    SCIENCE SHOULD UNFREEZE. SCIENCE SHOULD ADJUST ITS VISION, COMPREHENSION AND CONCEPTS.
