From Precis to Proof in 6000 years

Religious texts, such as The Holy Bible appear to be like a Precis of works from God. He seems to be explaining energy-dependent creation in the context of what is currently known to serious scientists about biophysically constrained RNA-mediated protein folding chemistry, healthy longevity and RNA-mediated biodiversity. God made it perfectly clear, in advance, that all miraculous biodiversity is energy-dependent. Energy as information is the theme that extends to the weekend resurrection of the bacterial flagellum in P. fluorscens. Biologically…

Cracking the Olfactory Code?

What a smell looks like Excerpt:  This experiment was created so scientists could study how animals and humans use smells to navigate their surroundings. That question forms the heart of a new $6.4 million project, sponsored by the National Science Foundation and the White House Brain Initiative, called Cracking the Olfactory Code. My comment to the PBS site: Re: “Smell was part of very ancient evolution…. Bacteria use olfaction, single-celled organisms use olfaction, worms use olfaction.” The de novo creation…

Eliminating correlations from evolutionary ecology

De novo creation of olfactory receptor genes clearly links food odors via amino acid substitutions to cell type differentiation in mosquitoes, and in nematodes, flies, honeybees, etc. It would be surprising if cause and effect did not extend to vertebrates from invertebrates. Indeed, Elekonich and Robinson (2000) linked our 1996 model of RNA-mediated cell type differentiation to hormone-organized and hormone-activated behavior in insects more than a decade ago. Since then, Vosshall’s lab has established the role that amino acid substitutions…
