We’re not sure yet if a father’s experience can affect the health of offspring.
Stress — it’s never good for you. But sometimes, it’s worse.
In a collaborative effort by the Oregon Healthy and Science University and the University of Pittsburgh researchers have been able to identify the genes whose role is to trigger the onset of puberty, and manipulate them to delay puberty in female rats. They hope that the discovery will help determine exactly why causes early-onset puberty in females.
In a testament to epigenetics, researchers show that it’s possible that the marks of trauma can be transmitted down to subsequent generations.
Florida worker ants doubled in size after scientists performed chemical changes to their DNA. The ants were not genetically modified per se, not in the conventional sense that implies altering their code. Essentially, the ants were exposed to a chemical, environmental changes that mimicked those found in their colony and which lead to ants of various sizes and behaviors despite sharing the same genes – a perfect example of epigenetics.
