Converting sunlight to fuel: O2 and CO2 Reactions

Physics

Efficient solar-to-fuels production from a hybrid microbial–water-splitting catalyst system Abstract excerpt:  “…we report the development of a scalable, integrated bioelectrochemical system in which the bacterium Ralstonia eutropha is used to efficiently convert CO2, along with H2 and O2 produced from…

Sneaking up from behind

ISHE 2013 Poster photo

I’ve been busy following the current research and attempting to discuss it, which led me to not finish this blog post. I started writing it last week. Since then, as I had anticipated, others have tried to sneak up from…

Thermodynamic constraints and ecological adaptations sans evolution

Physics

Relationship between protein thermodynamic constraints and variation of evolutionary rates among sites Excerpt: “…a two-variable model that combines stability and stress signi ficantly improves predictions. Therefore, both the overall stability [symbol] and the stress [symbol] seem to capture distinct thermodynamic constraints on…

RNA eclipses the importance of DNA to cell type differentiation

Why skin cells are skin cells and not neurons Excerpt: “…we’re using this approach to identify how the epigenome changes when plants are exposed to challenging environmental conditions, such as drought or high temperature, and how these changes might prime…

The importance of olfactory receptors

Smell Turns Up in Unexpected Places By ALEX STONEOCT. 13, 2014 Excerpt: “I’ve been arguing for the importance of these receptors for years,” said Dr. Hatt, who calls himself an ambassador of smell, and whose favorite aromas are basil, thyme…

RCas9: A programmable RNA editing tool Excerpt: “The researchers envision a wide range of potential applications for RCas9. For example, an RCas9 tethered to a protein translation initiation factor and targeted to a specific mRNA could essentially act as a…

Stem cell memory is biophysically constrained (2)

translocated chromosome

If stem cell memory is biophysically constrained, by nutrient-dependent pheromone-controlled amino acid substitutions, we can expect to find experimental evidence that conserved molecular mechanisms link the basic principles of nucleosome retention in plants to nucleosome retention in mouse and human…

Different physical locations and different molecular mechanisms of health and disease

Reappraisal of known malaria resistance loci in a large multicenter study Abstract excerpt: “The finding that G6PD deficiency has opposing effects on different fatal complications of P. falciparum infection indicates that the evolutionary origins of this common human genetic disorder…

Physics, Chemistry, and Molecular biology (PCMb)

human-evolution

Physics, Chemistry, and Molecular biology (PCMb) link ecological variation to ecological adaptations via a model of gene-cell-tissue-organ-organ system complexity that I first presented in 1992. After adding gene activation by pheromones, I co-authored a book that linked the pheromone-controlled physiology…

Physics denied; pseudoscientific nonsense accepted

Physics

  The events depicted are now portrayed in the context of Genome Dynamics Events, which are biophysically-constrained RNA-mediated events. RNA-mediated events lead to amino acid substitutions that differentiate the cell types of species. For example: “…the so-called alpha chains of…
