The difference in male and female longevity may be originating at the genome level, say Japanese researchers who suggest that the sperm genome has a detrimental effect on longevity in mammals. Their study, published in the journal Human Reproduction, found that female mice produced by using genetic material from two mothers but no father live […]
Hot or not? Men agree on the answer but women don’t. So says a new study from Wake Forest University psychologists that found there is much more consensus among men about whom they find attractive than there is among women. “Men agree a lot more about who they find attractive and unattractive than women agree […]
Researchers at the University of Missouri have established that maternal diet can influence the gender of offspring and that sheep fed a diet enriched with omega-6 fats have a significantly higher chance of giving birth to male offspring. The study, carried out by researchers from the Division of Animal Sciences and reported in the journal […]
No matter the species, males evolve flashier features and more melodious warbles in an eternal competition to win the best mates, a concept known as sexual selection. Charles Darwin first noted that males appear to evolve more quickly than females, but why this is the case has, until now, been something of a mystery. “It’s […]
Intriguing research from Penn State University shows that air pollution has a bigger effect on the immune system of females than males – at least in mice. The experiments showed that ozone – a major component in air pollution – markedly reduced the females’ ability to fight off pneumonia. Ozone is a major pollutant in […]
A new study from the University of Pittsburgh has found that during the past thirty years, the number of male births has steadily decreased in the U.S. and Japan. Perhaps more worryingly, the study, published in Environmental Health Perspectives, also found that an increasing proportion of fetuses that die are male. In Japan, among the […]
Neuroscientists from Georgetown University Medical Center say that boys and girls use different parts of their brains to process some basic aspects of grammar. Their study, published in the journal Developmental Science, suggests that gender is an important factor in the acquisition and use of language. It appears that girls mainly use a system that […]
