In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from ...

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

A study published in Nature by researchers at IRB Barcelona and the University of Washington shows that smoking and biological sex influence how mutated cells expand in healthy bladder tissue. The ...

Human cells usually contain two copies of most genes, one of which comes from the mother while the other comes from the father. It's long been thought that usually these two copies, or alleles of ...

Women tend to live longer than men, and while the extra years can be partially attributed to biology, behavioral differences also contribute to the sex-based gap. Men are more likely to engage in ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random ...
