Scientists Find That Genes Have Help in Determining Our Traits

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.

“This mechanism may help explain how ordinary

Turn Skin Cells into Stem Cells

New technique removes several hurdles in generating induced pluripotent stem (iPS) cells, smoothing the way for disease research and drug development.

Stem cells are ideal tools to understand disease and develop new treatments; however, they can be difficult to obtain in necessary quantities. In particular, generating induced pluripotent stem (iPS) cells can be an arduous task because reprogramming differentiated adult skin cells into iPS cells requires many steps and the efficiency is very low – researchers might end up with only a few iPS cells even if they started with a million skin cells.
