Food odors and chemosignals in body odor

social interaction and brain

A Sniff of Happiness Excerpt: We observed that exposure to body odor collected from senders of chemosignals in a happy state induced a facial expression and perceptual-processing style indicative of happiness in the receivers of those signals. Our findings suggest…

Lost archives and cell type differentiation information

The life cycle of an mRNA in a eukaryotic cell RNA is transcribed in the nucleus processing, it is transported to the cytoplasm and translated by the ribosome. Finally the mRNA is degraded

A Sexologist and his two Archives: Erwin J. Haeberle Excerpt: I did read the great study Die Prostitution (1912) by Iwan Bloch, one of the great pioneers of sexology. My comment: See also by Iwan Bloch: Odoratus Sexualis: A Scientific And…

Hiding things about neo-Darwinism

Genetic code

Biologists devise invasion plan for mutations Excerpt:  “…researchers describe a technique for creating mutations that invade the genome and transmit themselves across to the next generation with near 100% success, defying the classic laws of Mendelian genetics.” My comment: Placed…
