Human neural stem cells, the foundational cells for the brain and spinal cord, demonstrate a high susceptibility to infection by SARS-CoV-2, including the original viral spike and the Omicron variants (BA.1 and BA.2).

Researchers have characterized the "average" human genome using whole-genome sequencing from nearly one million individuals, revealing that extensive genetic variation, including the presence of disease-associated mutations, is a universal biological baseline rather than a physiological anomaly.

Moderately cold temperatures activate a metabolic pathway involving the metabolite dihydrobiopterin (BH2), which delays aging and protects against age-related neurodegenerative diseases by preserving protein homeostasis.

Humans began to wear clothing 170,000 years ago

Genetic data suggest that body hair was lost ∼1.2 Ma ... 3 Ma

Parasites are an ideal for determining when clothing use first began in hominins.

The human louse (Pediculus humanus) is a single species that occurs as two ecological types (head and clothing lice). Determining when head and clothing lice began to diverge provides a date by which clothing must have been in regular use by humans.

Origin of Clothing Lice Indicates Early Clothing Use by Anatomically Modern Humans in Africa https://academic.oup.com/mbe/article/28/1/29/984822?login=false

LRBA deficiency is a rare and severe autoimmune disorder caused by a genetic mutation that disrupts crucial protein recycling pathways within the cell, leading to the accumulation of enlarged endolysosomes and subsequent immune dysfunction.
