TL;DR: An exclusive choice procedure is established in which ~15% of outbred rats chose alcohol over a high-value reward, including high motivation to obtain alcohol and pursuit of this drug despite adverse consequences, and may offer targets for new pharmacotherapies for treating this disorder.

TL;DR: This study is the first to show transgenerational effects of early life stress in a precocial species by combining behavioral, endocrinological, and transcriptomic measurements.

TL;DR: The results show that epigenetic variation is inherited in chickens, and it is suggested that selection of favourable epigenomes, either by selection of genotypes affecting epigenetic states, orBy selection of methylation states which are inherited independently of sequence differences, may have been an important aspect of chicken domestication.

TL;DR: The results suggest that, in WL the gene expression response to stress, as well as some behavioural stress responses, were transmitted across generations, and the ability to transmit epigenetic information and behaviour modifications between generations may have been favoured by domestication.

TL;DR: It is reported that human sperm are acutely sensitive to nutrient flux, both in terms of sperm motility and changes in sperm tsRNA, and shared diet-sensitive mechanisms between sperm Motility and the biogenesis of tsRNA are suggested, which provide novel insights about the interplay between nutrition and male reproductive health.
