For decades, biology textbooks have been clear – our traits are the product of our genes. But a new study by Yale University researchers published Dec. 26 in Nature Genetics suggests another mechanism can regulate variations of traits even in genetically identical individuals.
A particular type of RNA works in concert with a common protein to protect organisms from harmful genetic variations without the help of genes, reports Haifan Lin, director of the Yale Stem Cell Center, professor of cell biology and genetics and senior author of the paper.

Baldness is an undesirable condition that afflicts both men and women, many of which have family members with significant hair loss. According to Health Day News, a new study of stem cells in mice shows promise for future treatments for people who battle hair loss.
The study was conducted on the fatty skin layers of mice by researchers at Yale University. Specifically, adipose precursor cells were found to spur new hair growth in mice, according to Health Day News.
Stem cells are present in hair follicles, which help generate hair growth. Health Day News explains that these cells are still present
