These GEITP pages have often discussed evolution and dispersal (migration) of hominins (i.e. any species of early human that is more closely related to humans than chimpanzees — including modern human) during the past 6 million years. The time period … Continue reading →

NASA scientists offer new clues to how life started on Earth after reproducing the origins of life on the ocean floor in a lab Nebert, Daniel (nebertdw) Tue 2/26, 1:37 PM I

These GEITP pages have often discussed genome-wide association studies (GWAS). GWAS are studies in which some phenotype (trait) is selected to be studied, and then thousands of individuals’ genomes are screened for statistically significant genetic loci associated with that selected … Continue reading →

By popular demand from more than several GEITP’ers, I am sharing the Tues Feb 19th front-page article in the Los Angeles Times. Often we at GEITP have chatted about Ed Calabrese and his uncovering of the fraud surrounding the Biological … Continue reading →

This topic is an excellent gene-environment interactions example. Attack of a fungus (environmental signal) on the host (a corn plant) results in genes (responding to the environmental signal) that mobilize a chemical (kiwellin-1) to defend itself against the invading fungus. … Continue reading →

As a human geneticist, I have always been interested ethical behavior, i.e. in how each individual patient might agree to undergoing a particular “genetic test” versus refusing to have such a test — based on many factors (age, gender, trait … Continue reading →

The present GEITP topic here is something that might revolutionize our thinking about RNA processing in all eukaryotes (i.e. organisms such as yeast or human having chromosomal pairs, as opposed to prokaryotes such as bacteria that have single unpaired chromosomes). … Continue reading →

This article is from the Science section of the New York Times this last week. I had the “gut feeling” that this was true, but now we have an actual mathematically quantifiable study to demonstrate this conclusion. DwN A new … Continue reading →

As these GEITP pages have discussed previously, the ligand-activated transcription factor aryl hydrocarbon receptor (AHR), is one of 110 members of the human BHLH gene superfamily of sensors that continuously monitor incoming signals (both exogenous and endogenous i.e. from both … Continue reading →

Two or more diet beverages a day is linked to high risk of stroke, heart attacks Nebert, Daniel (nebertdw) For a change-of-pace on these GEITP pages, below is a perplexing article today from CNN_News.com, describing an epidemiology study. Needless to … Continue reading →
