Summary: Identical nucleotide sequences link energy-dependent changes in binding sites to different amino acids in different proteins. The binding sites are conserved in the orthologous mammalian genes. The in vivo structure of biological membranes and evidence for lipid domains Scientists investigate how the sense of smell works in bacteria Biogenic non-crystalline U(IV) revealed as major … Hard Science vs the neo-Darwinian “magic box”
Noncoding RNAs Not So Noncoding Excerpt: “Were there going to be dozens of [micropeptides]? Were there going to be hundreds, like there are hundreds of microRNAs?” says Ingolia. “We just didn’t know.” See also: Number of microRNAs in Human Genome Skyrockets Excerpt: “…researchers from Thomas Jefferson University in Philadelphia have released data that adds another … Secular humanism and ecoterrorism
Epigenetic (re)programming of caste-specific behavior in the ant Camponotus floridanus Excerpt: Our results suggest that behavioral plasticity in animals may be regulated in an epigenetic manner via histone modification. My comment: Experimental manipulation of a single gene changed behavior. The evidence suggests all invertebrate and all vertebrate morphological and behavioral phenotypes can be linked via … Epigenetic (re)programming of behavior
Genetics probe identifies new Galapagos tortoise species Excerpt 1) Their paper1, published in PLoS ONE on 21 October, is the culmination of a decade of work. It presents 25 mitochondrial DNA mutations that reliably separate the two groups. Excerpt 2) “The species concept is a fuzzy one,” he says. “Call them whatever you want, I … Mutated mitochondrial genes vs Supercoiled DNA
