A study suggests that an X-linked gene called KDM6A, which is more active in women, may contribute to higher rates of multiple sclerosis in women by promoting brain inflammation. Deleting this gene in female mice reduced symptoms, and the drug metformin showed potential in calming inflammation, indicating sex-specific treatment possibilities.

A study analyzing over 12,000 brain scans found that male brains tend to shrink faster than female brains with age, with men showing more decline in various brain regions, though women may experience faster hippocampal decline later in life. The research highlights significant sex differences in brain aging, emphasizing the need for more gender-focused studies in neuroscience.

A large MRI study found that men's brains shrink faster than women's during aging, suggesting that age-related brain volume loss does not explain why women are more frequently diagnosed with Alzheimer's disease, prompting further research into other factors like susceptibility and survival differences.

Research shows that female animals generally live longer than males, with patterns varying across species and environments. In mammals, females tend to outlive males due to genetic and reproductive factors, especially in the wild, while in birds, males often have the longevity advantage, possibly due to reproductive costs borne by females. These differences are influenced by genetics, sexual selection, and ecological pressures, and are not universal but context-dependent.

The study reveals that female kidney tissues are resistant to ferroptosis and acute kidney injury due to the protective effects of oestradiol, which acts through non-genomic antioxidant mechanisms and ESR1-dependent pathways, while male tissues are more susceptible due to higher ether lipid plasticity and lower hydropersulfide levels.

Research reveals that a specific brain circuit in mice, influenced by hormones like oxytocin and ovarian hormones, governs sex-specific mating behaviors, promoting receptivity in females during estrus and reducing interest in males, with the same neurons having opposite effects in males, highlighting how hormonal states and sex shape social and sexual behaviors.
