Over the … Continue Reading First liver-generated hormone to work with brain to control sugar-intake identified.
A fundamental law of genetics states that progenies do not inherit epigenetically-based adaptive, pathological or neural features acquired in response to environmental conditions. However, recent studies seem to contradict this … Continue Reading Researchers map ‘epigenetic inheritability’ in fathers sperm caused by diet.
