A small RNA in Pseudomonas triggers an avoidance response in C. elegans that can be passed on to the next generation, according to research presented at this week’s meeting of the American Society for Cell Biology.

Two research groups demonstrate that in Caenorhabditis elegans, behavioral traits can be passed down through the germline to future generations, even though they aren’t hard-wired.

Mouse fathers whose sperm lacks the gene Kdm6a pass down altered methylation patterns to male offspring, along with a better chance of developing tumors and dying.

A large study seeks to answer whether a man’s childhood diet has transgenerational repercussions.

A study suggests that the direct transfer of DNA methylation marks from one generation to the next is much less common than scientists previously thought.

Fluoxetine dampened stress responses in zebrafish embryos exposed to the drug—and their descendants.

Identifying the molecular interactions that occur all over the body during exercise could reveal how it affects learning and memory.

As researchers unravel the molecular machinery that links exercise and cognition, working out is emerging as a promising neurotherapy.

Male rodents exposed to nicotine had changes in sperm genome methylation and produced pups and grandpups with abnormal behavior.
