"A new Tel Aviv University study pinpoints the precise mechanism that turns the inheritance of environmental influences "on" and "off." The research, published last week in Cell and led by Dr. Oded Rechavi and his group from TAU's Faculty of Life Sciences and Sagol School of Neuroscience, reveals the rules that dictate which epigenetic responses will be inherited, and for how long.

"Until now, it has been assumed that a passive dilution or decay governs the inheritance of epigenetic responses," Dr. Rechavi said. "But we showed that there is an active process that regulates epigenetic inheritance down through generations."
