Assembling yourself: Molecular self / other recognition

Chiral recognition and selection during the self-assembly process of protein-mimic macroanions Abstract excerpt: “We believe that delicate long-range electrostatic interactions could be responsible for such high-level chiral recognition and selection.” Article excerpt: “This self-assembly allows relatively simple building blocks to organize themselves into larger supramolecular structures, a phenomenon that has parallels with the formation of viral capsids (both in morphology and kinetics)37.” Reported as: Discovery demystifies origin of life chirality phenomenon Excerpt: “The origin of life is still a mystery…

Implicating microRNAs in cancer

Genome-wide CRISPR Screen in a Mouse Model of Tumor Growth and Metastasis Reported as: In vivo CRISPR-Cas9 screen sheds light on cancer metastasis and tumor evolution Excerpt: “Unexpectedly, the screen also implicated several microRNAs — small RNA segments that are functional in the cell. More experimental work remains to fully explore the genes and microRNAs uncovered in the screen.” It is the perturbed balance of viral microRNAs and nutrient-dependent microRNAs that obviously makes the difference between RNA-directed DNA methylation and…

Jumping back: Science or Pseudoscience?

Daily Comment November 21, 2014 European Science’s Great Leap Backward By Michael Specter Excerpt 1) “When politicians reject verifiable data and reputable research and rely instead on politics or desire, the results can be devastating.” Excerpt 2 with my emphasis) “…scientific organizations from around the world… have strongly endorsed the safety of G.M. foods. (It should be noted that the U.S. can claim no superiority in our approach to evidence-based science, as demonstrated by the fact that nearly half of…

Glycine and GnRH: Am I being pedantic?

Posted to the FB page on 12/3/14 at Skeptics; Atheists; Realists; Agnostics; Humanists Stephen Hawking and Brian Cox take part in Monty Python sketch – video Excerpt: “I think you are being pedantic.” My comment: Some people may think I am being pedantic. My focus is not on physics; it is on the role of GnRH in cell type differentiation. My focus now extends from what is known about quantum physics, quantum smell, chirality, quantum biology, and quantum consciousness. What is known about chirality…

No excuses: Creation and the meaning of organismal complexity

E.O. Wilson On ‘The Meaning Of Human Existence’ Excerpt: “We’re one species — glorious though we are — we are just one species out of an estimated eight million,” Wilson said. “At the present time, we only know almost exactly two million species — enough to give them a scientific name. Six million species are out there, maintaining the planet for us as an autonomous ecosystem and stabilization system. Book Excerpt: ‘The Meaning of Human Existence’ “Six million species are…

How Do You Know When You’ve Found Them All? A Question That Applies To Beetles and Cancer Genes Alike by Carl Zimmer Conclusion: “Cancer biologists and beetle experts are not all that different when you think about it. They walk the same foggy road together, a long way from the end.” My comment: Only the cancer biologists and beetle experts who believe in mutation-driven evolution are walking a road together. It’s not a foggy road. It’s brain fog that makes them similar.…
