... Largest Sky Map Revealed: An Animated Flight Through the Universe. The first public data release from BOSS, the Baryon Oscillation Spectroscopic Survey. Led by Berkeley Lab scientists, the Sloan Digital Sky Survey's BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure. The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). ---Please subscribe to Science & Reason:• This animated flight through the universe was made by Miguel Aragon of Johns Hopkins University with Mark Subbarao of the Adler Planetarium and Alex Szalay of Johns Hopkins. • Music: The Cinematic Orchestra - "Arrival of the Birds"

Climate change and mountain building led to mammal diversity pat Travel from the tropics to the poles, and you'll notice that the diversity of mammals declines with distance from the equator. Move from lowland to mountains, and you'll see diversity increase as the landscape becomes more varied. Ecologists have proposed various explanations for these well-known "biodiversity gradients," invoking ecological, evolutionary and historical processes. New findings by University of Michigan researchers John A. The results, published online in the journal Proceedings of the Royal Society B, also have implications for conservation efforts in the face of modern-day global warming, said Finarelli, a visiting assistant professor in the Department of Geological Sciences. In their study, focused on the Miocene Epoch, which began around 23 million years ago and ended about 5 million years ago, Finarelli and Badgley evaluated diversity for more than 400 rodent species from adjacent regions that differed in geologic history and topography.
