Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX. These genetic variants may play a role in promoting abnormal blood cells (that have only a single copy of chromosome X) to multiply, which may lead to several health conditions, including cancer.

Researchers have reconstructed the evolutionary history and global spread of malaria over the past 5,500 years, identifying trade, warfare, and colonialism as major catalysts for its dispersal.
