This GEITP topic has to do with how domestication and selective breeding of a wild fruit (foraged by our hunter-gatherer ancestors) has resulted in such a succulent, fragrant, and tasty fruit available in today’s grocery stores and supermarkets (i.e. the … Continue reading →

Today’s GEITP topic is an obstetric curiosity — sometimes found clinically during fertilization. Twins are traditionally classified as monozygotic (“identical”) or dizygotic (“fraternal”). Monozygotic twinning results in genetically identical (more or less identical, although many epigenetic differences between twin-pairs have … Continue reading →

The present [attached] article is an example of the incredible advances in technology (single-cell transcriptomics, in particular) that can now be performed in the field of developmental biology, and especially early-embryogenesis. The 48-hr period of mouse embryonic development — from … Continue reading →

There are several reasons these GEITP pages continue to share publications dealing with genome-wide association studies (GWAS). One, GWAS are becoming very common (due to lower costs, efficiency of carrying out). Two, GWAS are including much larger sample sizes (of … Continue reading →

As these GEITP pages continue to report, genome-wide association studies (GWAS) represent a screen of large portions of the entire genome (genotype), plus an attempt to find highly significant statistical significance (P < 5.0 x 10–8; also designated as P … Continue reading →

—Some of you might find this an interesting read. From the latest issue of Sci Am.

One of the most recent GEITP chats concerned the “possibility that genes talk to one another,” and the “likelihood that cells in any tissue talk to one another.” This editorial article [attached] is a semi-layman’s story about subcellular organelles (various … Continue reading →

Thanks, S…… I’ve ALWAYS been fascinated with the idea of the “genome as a community.” When scientists knock out one gene — in one cell-type (or globally) — this loss is somehow “sensed.” Then the genome “sets up a committee,” … Continue reading →

There are intriguing differences in the rate of human twinning worldwide — with less than eight per 1000 live births in Asia to greater than 18 per 1000 live births in Central Africa. Such geographic variations are mainly due to … Continue reading →

An entire issue of Chemico-Biological Interactions (published 1 March 2019) is devoted to the topic of the Linear No-Threshold (LNT) Model. [Attached] is the contribution by Ed Calabrese, who says this “represents my most comprehensive assessment yet, of this topic.” … Continue reading →
