Volcanoes Deliver Two Flavors of Water

Seawater circulation pumps hydrogen and boron into the oceanic plates that make up the seafloor, and some of this seawater remains trapped as the plates descend into the mantle at areas called subduction zones. By analyzing samples of submarine volcanic glass near one of these areas, scientists found unexpected changes in isotopes of hydrogen and […]

How dinosaurs measure up with laser imaging

Karl Bates and his colleagues in the palaeontology and biomechanics research group have reconstructed the bodies of five dinosaurs, two T. rex (Stan at the Manchester Museum and the Museum of the Rockies cast MOR555), an Acrocanthosaurus atokensis, a Strutiomimum sedens and an Edmontosaurus annectens. The team, whose findings are published in the Public Library of Science journal PLoS ONE today (19th February […]

Animal life existed 30 million years earlier than previously known.

University of Alberta scientists say they’ve proven animal life existed 30 million years earlier than previously known. Geologists Ernesto Pecoits and Natalie Aubet found fossilized tracks in Uruguay they believe was left behind by a slug-like creature at least 585 million years ago. Kurt Konhauser, a geomicrobiologist at the university, co-authored the study published Thursday […]
