Sun spotless for 33 days straight – airline travelers getting dosed with up to 70 times more radiation [than at sea level]

This information does not bode well for predictions of further “global warming” — In fact, the lowered solar activity could cause “global cooling” again. Ugh. Colder, snowier winters..?? ☹ Sun spotless for 33 days straight – airline travelers getting dosed … Continue reading

Transgenic Metarhizium rapidly kills mosquitoes in a malaria-endemic region

Transgenic Metarhizium rapidly kills mosquitoes in a malaria-endemic region Nebert, Daniel (nebertdw) Thu 6/20, 2:07 PM The topic of today’s GEITP article is using a genetically-modified organism (GMO) to control a pest; this is an interesting “gene-environment interactions” type of … Continue reading

The Polycomb-Dependent Epigenome Controls Beta-Cell Dysfunction, Dedifferentiation, and Diabetes

These GEITP pages have often discussed the fact that complex diseases almost always represent multifactorial phenotypes (traits) — (e.g. hypertension, schizophrenia, mental depressive disorder, cancer, autoimmunity, obesity, and diabetes) — which reflect contributions from genetics (alterations in DNA sequence), epigenetic … Continue reading

Adaptive introgression enables evolutionary rescue from extreme environmental pollution

So that everyone is “on the same page,” let’s consider the classical example of horse-donkey breeding (i.e. two different species). Usually, the male donkey (jack) mates with a female horse (mare) to produce a mule (they can be either sex). … Continue reading

New historical perspectives as to how/why EPA adopted the Linear-Non-Threshold (LNT) Model

This article [see attached] is the latest historical analysis — in a long series by Ed Calabrese — on details surrounding acceptance of the Linear Non-Threshold (LNT) Model in 1975 by the U.S. Environmental Protection Agency (EPA). In 1956, the … Continue reading

A missense variant in the FTCD gene (other than the AS3MT gene)) affects arsenic metabolism and toxicity phenotypes in Bangladesh

This topic is very central to gene-environment interactions (i.e. if everyone in a population is exposed to the same undesirable levels of arsenic — why isn’t the toxic response similar) Exposure to inorganic arsenic forms (iAs) in contaminated drinking water … Continue reading
