Researchers have identified the gene NANOG as the key switch that initiates the developmental program resulting in cells forming a human body. The finding came from precise DNA edits to fertilized human eggs using CRISPR base editing.

Researchers have discovered that mutations in the CD99L2 gene cause X-linked spastic ataxia, a rare movement disorder. The finding came from analysis of 2,811 patients with conditions affecting coordination and muscle control. The study was published in Nature Communications.

A newly published study suggests that a tiny fraction of human DNA plays an outsized role in language ability. Researchers at the University of Iowa found these genetic regions were present before modern humans and Neanderthals diverged. The findings push back the timeline for the biological basis of language.
