Moderate alcohol consumption can boost male fertility

While some newborns are inherently more "talkative" than others, a recent study published in iScience indicates that there are disparities in the amount of noises made by males and females

Researchers at Osaka Metropolitan University found that familiar and affordable foods can help create a society where people are healthier and less stressed. Japanese natto, which is made from softened soybeans that have been boiled or steam-fermented with a bacteria known as Bacillus subtilis var. natto, might be one example of such a food. The study was published in the journal, 'Journal of Applied Microbiology'.

The 'meal-recall effect', or remembering a recent meal, might restrict how much food a person consumes later. Researchers from the University of Cambridge investigated the effect on meal-recall of believing that a recent meal was twice as big and gratifying as reality or recalling a recent meal in detail (e.g., what it felt like to chew and swallow the food).

In preclinical models, an investigational contraceptive medication created by Weill Cornell Medicine researchers temporarily inhibits sperm and prevents pregnancies. The study, which was published in Nature Communications on February 14, reveals the feasibility of on-demand male contraception.

The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more new mutations are inherited from fathers than from mothers. It doesn't, however, clarify why older fathers pass on more mutations than younger ones do. The mechanisms that might underlie these well-documented trends have long remained a mystery. Now, a new study in the journal Nature Ecology & Evolution by Rockefeller University scientists describes why older male fruit flies are more likely to pass mutations onto their offspring, potentially shining a light on inherited-disease risk in humans.
