Horton told last month 's meeting of the american geophysical union in san francisco that this suggests the animals are somehow sensing this ratio , perhaps relying on the symmetry of the bio-magnetite crystals they are thought to use to detect the magnetic field .
Elsewhere , in the journal geophysical research letters , investigators from the university of colorado have identified a new mechanism by which meltwater flows through networks of crevasses and fractures inside glaciers to warm the ice more than projected by climate models .
