For the first time, scientists have created pigs, goats and cattle that can serve as viable “surrogate sires,” male animals that produce sperm carrying only the genetic traits of donor animals.
In the past decade, knowledge of how lifestyle affects our genes, a research field called epigenetics, has grown exponentially. Researchers at the Lund University Diabetes Centre have summarised the state of scientific knowledge within epigenetics linked to obesity and type 2 diabetes in a review article published in the scientific journal Cell Metabolism.
Over the past quarter-century, researchers have published hundreds of studies suggesting a small set of particular genes or gene-variants plays a substantial role in boosting susceptibility to depression. Such papers fueled hopes that clinicians could soon use genetic testing to simply identify those at risk, and drug companies could develop medications to counteract a few genetically driven culprits.
A new treatment for patients with a form of congenital retinal blindness has shown success in improving vision, according to results published today in Nature Medicine led by researchers at the Scheie Eye Institute in the Perelman School of Medicine at the University of Pennsylvania.
