I cannot claim to be an expert on artificial intelligence (AI) or machine-learning, but I would say that the essence of this approach is as follows: Many things in science (more so in biology than perhaps in chemistry, and even … Continue reading →

Far northeastern Siberia was the gateway to the Americas for ancient humans; today it is home to diverse cultures whose members speak many languages. During the Late Pleistocene period [i.e. the Last Glacial Period (LGP), lasting from ~126,000 to ~11,700 … Continue reading →

hese GEITP pages have followed the story, the ethical dilemma, of biophysicist Jiankui He (in late 2018, from the Southern Univ of Sci & Technol in Shenzhen, China), who reported births of twin girls whose genomes had been edited using … Continue reading →

As these GEITP pages have frequently described, because of the well-established field of mouse genetics (since early 20th-century) and whole-genome sequncing (WGS) of many sublines, mouse research has remained head-and-shoulders above any other animal model, with regard to extrapolation of … Continue reading →

“Evolution of life on Earth” has been among the various topics discussed in these GEITP pages, because gene-environment interactions play a major role in how organisms (all living things) continue to evolve — i.e. in response to advantageous, or adverse, … Continue reading →

From time to time, these GEITP pages consider topics on Evolution. In biology, there are six Kingdoms of Life: Archaebacteria, Eubacteria, Protists, Fungi, Plants and Animals. The first two are prokaryotes (microscopic single-celled organisms having unpaired chromosomes and neither a … Continue reading →

Mammalian life begins with fertilization of the egg. Once the egg and sperm have fused, the parental chromosomes need to be combined. It was previously taught that a single microtubule-spindle is responsible for spatially combining the two genomes, and then … Continue reading →

For anyone interested in SLE (systemic lupus erythematosus), this is a weird finding, maybe a paper worth investigating….. Symptoms of systemic lupus erythematosus are diagnosed in leptin transgenic pigs Junchen Chen, Weiqi Zeng, Weirong Pan, Cong Peng, Jianglin Zhang, Juan … Continue reading →

The full-length article about “genome size” [attached left pdf file] was shared with all of GEITP on Aug 31st, and that analysis is re-posted furthest below. The editorial commentary [attached right pdf file] was intended to accompany the full-length article. … Continue reading →
