RNA-mediated protein folding

The essence of precision medicine: drug targets or healthy longevity?

The molecular epigenetics of healthy longevity Trichome, a Functional Diversity Phenotype in Plant Abstract: Trichomes play a very important role in the process of evolution for plant which are epidermal appendages covering the surface of plants. In this paper, some progress concerning the genes responsible for trichome formation is presented for monocots and dicotyledons plants. Meanwhile, the special structures and physiological functions of trichome are briefly introduced, such as reflectance, energy balance, ultraviolet protection, drought resistance, gas exchange, insect resistance…

Polycombic ecological adaptation as a science, not a theory (2)

Evolutionary Constraints in the β-Globin Cluster: The Signature of Purifying Selection at the δ-Globin (HBD) Locus and Its Role in Developmental Gene Regulation Conclusion: … the results here presented indicate that purifying selection is driving not only HBD evolution but also its neighbor pseudogene, HBBP1. In the light of recent advances in the characterization of the β-globin cluster, we propose that the complex patterns of diversity observed in this genomic region arose from distinct functional constraints related with the intricate…

Attacking Young Earth Creationists

‘Residual diversity estimates’ do not correct for sampling bias in palaeodiversity data Abstract excerpt: Evolutionary dynamics such as speciation are inherently a phylogenetic process, and only an explicitly phylogenetic approach will correctly model this process. Reported as: Flawed analysis casts doubt on years of evolutionary research The method assumes that variations in the number of different fossils at any given time are a reflection of how much rock was available. It has been used in more than 150 published research…

Antithetical conclusions (7)

Streamlining the E.coli Genetic Code Once the E. coli genome is pared down to 57 codons, the seven blank codons can be reintegrated and used to introduce nonstandard amino acids, the researchers have proposed; this would open the door to creating a wider range of proteins for industrial applications. A recoded genome also imparts resistance to viral infection and can be used for biocontainment: the DNA incorporated from wild-type E. coli or viruses can’t be used to build proteins successfully…

From angstroms to ecosystems

How a happy moment for neuroscience is a sad moment for science Systems neuroscience is celebrating a landmark, but one that shows the way we do science is broken. Excerpt: These data are the first complete set of neural activity recordings released before publication. No papers preceded it; not even a report. Nothing. Just: here you go guys, the fruits of the joint labour of around 100 people over 4 years.” My comment: They released the information on June 13,…

Food supplement or licensed immunostimulant?

Glucan from Food Supplement to a Licensed Drug   Excerpt: “…β-glucan possesses a significant immunostimulating activity in a wide variety of species, including earthworms, shrimp, fish, chicken, rats, rabbits, guinea pigs, sheep, pigs, cattle, and, last but not least, humans. Based on these results, it has been concluded that β-glucan represents a type of immunostimulanting molecule that is actively spanning full evolutionary spectrum. Some experiments also show that β-glucan can help even in the protection of plants. β-Glucan is therefore…

Did “Nature” kill Steve Jobs?

See also: Energy-dependent RNA methylation (7) How cancer was created by evolution (revisited) Excerpt: Cell division in our bodies is very heavily controlled. For instance, when you were first growing your hands, some cells went through “cell suicide” – a process called apoptosis – to carve out the spaces between your fingers. My comment: Cell division is energy-dependent and the result is controlled by the physiology of reproduction in species from microbes to humans.  Energy-dependent RNA-mediated cell type differentiation must…

Innate immunity and multiplexing

Scientists Hope to Cultivate an Immune System for Crops by Carl Zimmer Excerpt: The complex microbial world in the soil may protect plants much like our immune system protects our bodies. My comment: The speed of light on contact with water links the sun’s quantized anti-antropic virucidal energy from the de novo creation of nucleic acid precursors to biophysically constrained RNA-mediated protein folding chemistry and supercoiled DNA, which protects all living genera from virus-driven energy theft and genomic entropy. See…

Amino acids and virus penetration

For an example of the ocean of information you must swim through to get to an important fact about virus-driven energy theft and all pathology, see: The bacteriophage ϕ29 tail possesses a pore-forming loop for cell membrane penetration (June 15, 2016) They cite “PrDOS: prediction of disordered protein regions from amino acid sequence” (2007). Excerpt: We have also developed a system to predict disordered regions from the amino acid sequence. Our system is composed of two predictors, that is, a…

Jay R. Feierman: twenty years of antagonism

Jay R. Feierman began his antagonism when we first met. At a poster presentation during a prestigious conference in 1995, I detailed all the aspects of my mammalian model. He asked “What about birds?” He is the”bird-watching” moderator of the International Society for Human Ethology (ISHE) yahoo group who banned me from participation last year when I failed to answer a “yes” or “no” question about the role of RNA in cell type differentiation. Since then, his attacks on my…
