ANIMATION University of Copenhagen researchers have discovered how mosses became one of our planet’s most widely distributed plants — global wind systems transport them along Earth’s latitudes, to rooftops, sidewalks, and lawns worldwide, and as far away as Antarctica. This new knowledge can provide us with a better understanding of […]

Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of zircons, researchers from the University of Copenhagen have shown that a population of these crystals were sourced from the deep interior […]
