Y chromosome found to play key role in making men taller than women
Height is one of the most evident sex-based differences observed in humans, as men are on an average 13 cm (5 inches) taller than women. Sex hormones certainly play a significant role in driving this dimorphism, but they ...
'Barcodes' written into DNA reveal how blood ages
A study in the journal Nature explains how age reshapes the blood system. In both humans and mice, a few stem cells, or "clones," outcompete their neighbors and gradually take over blood production. The blood stem cell reservoir ...
