SCIENCE TODAY: THE GENETIC HISTORY OF ICE AGE EUROPE

Three ~31,000-year-old skulls from Dolni Vestonice in the Czech Republic. For the next five thousand years, all samples analyzed in this study -- whether from Belgium, the Czech Republic, Austria, or Italy -- are closely related, reflecting a population expansion associated with the Gravettian archaeological culture.

SCIENCE DAILY: PRISTINE INNER SOLAR SYSTEM RETURNS

Artist's impression of the unique object C/2014 S3 (PANSTARRS). Observations with ESO's Very Large Telescope, and the Canada France Hawai`i Telescope, show that this is the first object to be discovered that is on a long-period cometary orbit, but that has the characteristics of a pristine inner Solar System asteroid. It may provide important clues about how the Solar System formed. Because the object has spent most of its life away from the inner Solar System it suffered very few collisions, and its surface displays few or no craters. As it formed in the same region as the Earth did, it is mostly rocky, and therefore has only very limited cometary activity.
