Thermotolerance and Longevity

Heterotypic Signals from Neural HSF-1 Separate Thermotolerance from Longevity Excerpt: …it was hypothesized that hsf-1 regulates the aging process by modulating chaperone network components to directly influence the folding state of the proteome ( Morimoto, 2008). Our data suggest an alternate method by which hsf-1 can regulate the aging process. In this model, hsf-1 activates Thermotolerance and Longevity

Chemical ecology and RNA-mediated control of DNA loops

DNA Loop-the-Loops A new full-genome map indicates how DNA is folded within the nuclei of human cells.By Kate Yandell | December 11, 2014 Excerpt: “…many loops were conserved among cell types, and even between mice and humans. But others seemed to drive cell type-specific gene expression patterns.” My comment to The Scientist Magazine: Nutrient-dependent/pheromone-controlled adaptive Chemical ecology and RNA-mediated control of DNA loops

Sexual differentiation of cell types in plants

Antheridiogen determines sex in ferns via a spatiotemporally split gibberellin synthesis pathway Excerpt: “Homosporous ferns have evolved a mechanism to favor cross-fertilization by controlling the sex ratio among individuals or prothalli within the population with the aid of antheridiogens. Antheridiogens are pheromones…” Reported as: Researchers find ferns communicate with one another to decide gender Excerpt: Sexual differentiation of cell types in plants

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

Systems biology and memory disorders

Epigenetically-effected metabolic shifts and ecological adaptations

Epigenetics of Trained Innate Immunity: Documenting the epigenetic landscape of human innate immune cells reveals pathways essential for training macrophages. By Ruth Williams | September 25, 2014 [open access] Excerpt: “…they then analyzed genome-wide distributions of four epigenetic indicators of gene activity: DNAse hypersensitivity and three different histone modifications—trimethylation of histone H3 at lysine 4, Epigenetically-effected metabolic shifts and ecological adaptations
