Ancient asteroid impact exposes the moon's interior



West Lafayette IN (SPX) Oct 16, 2017
Scientists have long assumed that all the planets in our solar system look the same beneath the surface, but a study published in Geology on Oct. 4 tells a different story. "The mantle of the earth is made mostly of a mineral called olivine, and the assumption is usually that all planets are like the Earth," said Jay Melosh, Distinguished Professor of Earth, Atmospheric and Planetary Sciences at Purdue University, who led the study. "But when we look at the spectral signature of rocks exposed deep ... read more

According to genetic analysis, Newfoundland, the northeastern Canadian island, was populated by three distinct groups - in three different waves - over the last 10,000 years. When scientists analyzed the DNA of two known cultural groups, the Maritime Archaic and Beothuk, they found the groups brought unique matrilines to the island. Until now, archaeologists thought the Beothuk ... more
