New method now enables scientists to study gene expression in single cells (“RNA velocity”)

When scientists (typically) determine “liver gene transcription, mRNA or protein level, or enzyme activity” –– the entire organ is homogenized and analyzed. Same with lung, kidney, brain, mammary or prostate gland, etc. However, each of these organs comprises multiple cell-types, … Continue reading

Diarrhea from taking laxatives can alter the microbiome

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

Questions from a Korean magazine and answers (by PROFESSOR RICHARD LINDZEN)

Questions from a Korean magazine and answers (by Richard Lindzen) to these questions: 1. A large part of the world including Europe and Northeast Asia suffered a long and severe heat wave this summer. What was the problem? The problem … Continue reading

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

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 ….!!!!

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

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

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

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

Selfish genetic element confers non-Mendelian inheritance in rice

As these GEITP pages have previously discussed, the ~3-billion base-pair (bp) genome of human comprises only ~1% of the DNA that is actually responsible for functional protein-coding genes (this portion, ~30 million bases, is called the “exome”). [Therefore, whole-genome sequencing … Continue reading

Questions from a Korean magazine and answers (by PROFESSOR RICHARD LINDZEN)-1

Various sources give slightly different times for “The Little Ice Age,” but a good estimate is “The Little Ice Age spanned from about 1550 to about 1850” –– which would make it mid-16th Century to mid-18th Century. In the middle … Continue reading

Honey bees apparently can “understand” that “zero” is different from “5” and also different from “6”

The number “zero” is central to contemporary mathematics, as well as to our scientifically and technologically advanced culture. Yet, it is a difficult number to truly “understand”. Children grasp the symbolic number “zero” –– long after they start to understand, … Continue reading
