Why large dogs age faster than small ones, and other October research highlights
Plus invisible tattoos, medieval skeleton gets an ID, trapping a single antimatter particle, and more.
October's scientific headlines include an intriguing discovery about dog aging, physicists' achievement in trapping antimatter, and innovative tattoo inks. Research from Arizona State University reveals that the lifespan disparity among dogs is linked to jumping genes, as reported in the journal Science. The study analyzed DNA methylation patterns in 864 dogs from the Dog Aging Project, with the epigenome serving as a chemical indicator of aging. Unlike fixed genetic sequences, DNA methylation is influenced by environmental factors like stress.
