The gradual erosion of layers of rock by rivers flowing through the Appalachian Mountains generates biodiversity of freshwater fish species, suggests a new Yale-led study that offers insight into the causes of species richness in the ancient mountain...
A wafer-thin slice of meteorite at the Yale Peabody Museum contains otherworldly gems. Olivine crystals, known as peridots to jewelers, are embedded in the specimen’s shiny iron-nickel alloy. When held to light, the yellow crystals glow brightly.
