Researchers identify the LypABC system used by bacteria to release gene transfer agents. This discovery explains how ancient viral components are repurposed to spread antibiotic resistance across microbial populations.
Ancient DNA from a 12,000-year-old Italian burial revealed an inherited bone growth condition (acromesomelic dysplasia) in a mother and child, proving rare genetic diseases existed in prehistory and highlighting paleogenomics' power.
Ancient DNA analysis of 4000-year-old skeletons in Chile suggests leprosy, caused by Mycobacterium lepromatosis, existed in the Americas long before European colonization. This challenges existing views.
