- Across the animal kingdom, individuals with identical sex chromosomes—including women with double Xs—live nearly 18% longer than their counterparts with mismatched chromosomes, a new study reveals. https://royalsocietypublishing.org/doi/10.1098/rsbl.2019.0867 51 comments science
- From humans to black-tailed prairie dogs, female mammals often outlive males – but for birds, the reverse is true. Now a new study reveals that having two copies of the same sex chromosome is associated with having a longer lifespan, suggesting the second copy offers a protective effect. https://royalsocietypublishing.org/doi/10.1098/rsbl.2019.0867 3 comments science
