The new light of chromosomal rearrangements

SCIENCE Seeing X Chromosomes in a New Light By CARL ZIMMER JAN. 20, 2014 NY TIMES Excerpt 1: In the journal Neuron, a team of scientists has unveiled an unprecedented view of X-chromosome inactivation in the body. They found a remarkable complexity to the pattern in which the chromosomes were switched on and off. My comment: The remarkable complexity of nutrient-dependent pheromone-controlled chromosomal rearrangements that led to difference in sex chromosomes was detailed in our 1996 Hormones and Behavior review article in the section on: Genetic…

Pulses of olfactory/pheromonal input

Signal and noise: Spike correlations in the olfactory system by John Hewitt Excerpt: “The olfactory system is not so much a hard-wired telephone network where channels can be instantaneously specified and connected by number codes, and then used to transmit further codes. There is significant overgrowth and back-pruning in olfactory networks during development, and some ongoing cell replacement, but once etched, many of its larger features remain stable.” My comment: This comparison is meaningful: “…any message can not stand out…

Functional coding variants are not mutations

Rare coding variants of the adenosine A3 receptor are increased in autism: on the trail of the serotonin transporter regulome “Conclusions: Our results validate the hypothesis that the SERT regulatory network harbors rare, functional variants that impact SERT activity and regulation in ASD, and encourages further investigation of this network as a site for additional functional variation that may impact ASD risk.” My comment: This open access article mentions mutations, but the title and conclusion correctly infer that coding “variants”…

  • What Darwin proved: there’s no such thing as a species
    GENETICS As Animals Mingle, a Baffling Genetic Barrier A short stretch of DNA is challenging what it means to be a species. By: Emily Singer August 5, 2014 Excerpt: “Scientists have dubbed such regions of the genome “islands of speciation.” The persistence of such islands is a phenomenon that has been observed in a variety of […]
