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.

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.
