Olfactory perception of genetic information

Individual olfactory perception reveals meaningful nonolfactory genetic information This open access journal article accurately represents what is currently known about nutrient-dependent RNA-directed DNA methylation and RNA-mediated events, which link the epigenetic landscape to the physical landscape of DNA via the de novo creation of olfactory receptors. RNA-mediated amino acid substitutions stabilize thermodynamic cycles of protein Olfactory perception of genetic information

MicroRNAs and the exposome

 MicroRNAs as Potential Signatures of Environmental Exposure or Effect: A Systematic Review Excerpt: Researchers are currently publishing extensive lists of miRNAs that are responsive to environmental exposures and showing their utility as biomarkers of effect. Future research should focus on identifying the molecular mechanism behind miRNA expression changes in response to exposure to determine whether MicroRNAs and the exposome

Imagining that data historically supports evolutionary theory

1) Arguments in the evo-devo debate: say it with flowers! Abstract excerpt: A key question in evolutionary developmental biology is how DNA sequence changes have directed the evolution of morphological diversity. The widely accepted view was that morphological changes resulted from differences in number and/or type of transcription factors, or even from small changes in Imagining that data historically supports evolutionary theory

Model organisms: the birds and the bees

Bird Genomes Abound Scientists complete the largest-ever comparative genomic study of birds. By Ruth Williams | December 11, 2014 Excerpt: “Birds are model organisms for a number of human behaviors and conditions—For example, Jarvis compares vocal learning in birds and humans—so determining the genetic basis of such traits requires genetic history.” My comment: Honeybees are Model organisms: the birds and the bees

No understanding of biodiversity

No single explanation for biodiversity in Madagascar Excerpt: “The study is part of a larger body of research aimed at identifying the climate, geology and other features of the environment that help bring new species of plants and animals into being in an area, and then sustain once they’re there.” My comment: Like many studies, No understanding of biodiversity
