BMSIS science featured in ‘Nature’ magazine

BMSIS scientist Sanjoy Som and collaborators from the University of Washington in Seattle published in ‘Nature’ a method to calculate the air density 2.7 billion years ago by measuring fossil raindrop imprints. The work, coupling experiments of falling raindrops with theoretical predictions of raindrop dynamics, allowed the scientists to constrain atmospheric density to at most 2x present levels, but rainfall statistics favor an air density more probably between 0.5x – 1.05x present levels.
