Two studies examining the effects of parents’ ages on their offsprings’ telomere lengths come to opposite conclusions.  

The findings contradict what has been observed in humans.  

The variation may help explain why stocked salmon don’t fare as well in the ocean.

The daughters of Finnish women separated from their parents as children during World War II have higher rates of psychiatric hospitalization than those born to women who had not been evacuated.

The memory of a temperature spike can persist for as many as 14 generations in C. elegans.

When kept at warmer temperatures for five generations, C. elegans showed evidence of “remembering” that experience for up to 14 generations.

Plants grown in dry soil produce offspring that are hardier in drought conditions, and DNA methylation appears responsible. 

Female rats fed a typical Western diet had offspring that were at higher risk of obesity than moms fed low-fat, high-grain meals.

Disease risk can be transmitted epigenetically via egg and sperm cells, a mouse study shows.
