Tiny genetic variations between humans, Neanderthals and Denisovans might not be all they were cracked up to be.

A new study finds removing race from breast cancer prediction models worsens calibration. The change underestimates risk for Black women and overestimates it for Asian women, potentially limiting access to supplemental screening.
