Early prediction of preterm birth in cell-free RNA could reshape prevention strategies
Children born before 37 weeks of gestation have a considerably increased risk of dying before they reach the age of five. Predicting the risk of preterm birth (PTB) and hence implementing preventive strategies is complicated ...

Mitochondrial DNA mutation accumulation may not be a determining factor in aging
The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria are cell organelles that produce energy ...

Novel gene therapy tools target inherited retinal degenerations at advanced stages
Inherited retinal degenerations (IRDs) are a group of genetic disorders that lead to progressive vision loss as the light-sensing cells of the eye—the photoreceptors—die due to mutations in genes needed for their function ...

Study identifies a new factor linked to heart failure
When the workload on the heart increases, the ventricular wall may thicken too, known as cardiac hypertrophy. This is an adaptive response that reduces pressure on the heart and maintains the activity of this vital organ. ...

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 ...
