Discovery of hydrogen-rich apatite in lunar rocks hinted at more watery past. Think again, says UCLA’s Jeremy Boyce.

The amount of water present in the moon may have been overestimated by scientists studying the mineral apatite, says a team of researchers led by Jeremy Boyce of the UCLA Department of Earth, Planetary and Space Sciences.

Boyce and his colleagues created a computer model to accurately predict how apatite would have crystallized from cooling bodies of lunar magma early in the moon’s history. Their simulations revealed that the unusually hydrogen-rich apatite crystals observed in many lunar rock samples may not have formed within a water-rich environment, as was originally expected.

Many Americans overestimate the degree of polarization between Democrats and Republicans, and this misconception is associated with citizens’ voting behavior and their involvement in political activities, according to new findings from the University of Colorado Boulder.

“It is clear that Americans see themselves as very sharply polarized,” said Professor Leaf Van Boven, who led the research efforts. “And that the extent of perceived polarization dramatically overstates the actual degree of polarization.” (more…)
