Unraveling the History of the India-Asia Collision
A study of deformed and metamorphosed rocks exposed in Tibet’s Lopu Range suggests that episodes of crustal shortening and extension during the evolution of the Himalaya are related to subduction processes.

Seismological Models Are Biased, but Scientists Have a Solution
Many seismic wave models are based on an erroneous assumption about the Earth's interior. A new technique corrects this by eliminating false signals produced by models.
