Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is exposed to stress or toxicants, can lead to metabolic and behavioral disorders in his offspring.

A new study shows that over 90% of insect biomass declines are driven by shrinking species numbers, posing a risk to ecosystem function.

Specialized appendage responds to female sex hormones, allowing males to find sex organs in the dark

The difference between the number of men and women listed as authors on scientific papers and inventors on patents is at least partly attributable to unacknowledged contributions by women scientists.

Surprising epigenetic effect relies on snippets of RNA packaged within sperm

In a recent study published in Cell Metabolism, a research paper provides the first evidence that sperm microRNAs act as carriers of epigenetic information, enabling the intergenerational transmission of paternal exercise capacity and metabolic health, thereby exerting profound effects on offspring development.
