Parallel altitudinal clines reveal trends in adaptive evolution of genome size in domesticated maize (Zea mays)

Posted on August 31, 2018 by DWN

GENOME SIZE varies by several orders of magnitude across species, due to both changes in ploidy (number of sets of homologous chromosomes that make up the genome of a cell or an organism) as well as haploid DNA content (one-half … Continue reading →

Triggers of tree mortality under drought conditions

Posted on August 31, 2018 by DWN

This is a gene-environment interactions topic. The “environmental signal” in this case is DROUGHT. Which genes in the tree’s genome will respond to the drought signal in order for the tree to survive? Forests provide a wide array of ecosystem … Continue reading →

Diarrhea from taking laxatives can alter the microbiome

Posted on August 30, 2018 by DWN

The findings of this study come as no big surprise to many of us. During the past 10+ years, clinicians and scientists have begun to appreciate the importance of The Microbiome –– all the bacteria that live in our intestine. … Continue reading →

Genome-wide association studies identify genes associated with “intelligence” and with “neuroticism”

Posted on August 28, 2018 by DWN

As we have often presented in these GEITP pages, we report here two HEROIC (large) genome-wide association studies (GWAS), which represent huge populations (cohorts) examined for DNA-sequence differences (virtually anywhere in the genome) that appear to be associated with a … Continue reading →

Discovery of genome of an offspring of a Neanderthal mother and a Denisovan father ….!!!!

Posted on August 24, 2018 by DWN

As these GEITP pages have often described, modern human (Homo sapiens) migrated out of southeast Africa during the past 1-2 million years. Neanderthals (Homo neanderthalensis), Denisovans (Homo denisova), modern humans, and one other (still a mystery) hominin subline most likely … Continue reading →

The world of fake journals and non-conferences

Posted on August 20, 2018 by DWN

From time to time, these GEITP pages, have covered this RISING MENACE of “predatory open-access online” journals. During the past decade –– this corrupt field of publishers has expanded from virtually none, to well over 15,000 “fake journals” today. And … Continue reading →

Decades of Mismanagement Turned US Forests into ‘Slow-Motion Time Bombs’

Posted on August 8, 2018 by DWN

Decades of Mismanagement Turned US Forests into ‘Slow-Motion Time Bombs’ wildfire calif Bob Zybach [PhD in Forestry. Oregon State University Environmental Sciences Program] feels like a broken record. Decades ago he warned government officials allowing Oregon’s forests to grow unchecked … Continue reading →

High-resolution comparative analysis of the Great Ape genomes: structural variation and brain-expressin differences

Posted on August 6, 2018 by DWN

In these GEITP pages, we have often chatted about primate evolution –– because evolution is a representation of the genes, in genomes of each species, interacting/responding to the environment, over extended time periods (hundreds, thousands; hundreds of thousands of years). … Continue reading →
