A team of scientists from King’s College London, University College London and the University of Manchester has identified 44 genes linked to age-related hearing loss. Wells et al performed genome-wide association studies for two self-reported hearing phenotypes, using more than 250,000 UK Biobank volunteers aged between 40 and 69 years. Image credit: Pexels. Age-related hearing impairment is the most common sensory impairment in the aging population;...

Extant and extinct sloths: in the tree, going clockwise from left -- extinct West Indian sloth (Acratocnus), extant three-fingered sloth or ai (Bradypus), and extant two-fingered sloth or unau (Choloepus); from left to right on the ground are representative giant ground sloths -- Mylodon (South America), Megalonyx (North America), and Megatherium (South America). According to the new molecular studies, Bradypus is most closely related to a group that includes Megalonyx and Megatherium. Choloepus is related to Mylodon, but Acratocnus and its West Indian kin represent a separate branch that is distinct from that of all other sloths. Human for scale: 1.85 m.
