Using radioactive elements trapped in crystallized, cream-colored “veins” in New Mexican rock, geologists have peered back in time more than 400,000 years to illuminate a record of earthquakes along the Loma Blanca fault in the Rio Grande rift. The work was led by postdoctoral researcher Randy Williams and his advisor, Laurel Goodwin, a professor in the geoscience department.

A new study, co-authored by Zhengyu Liu, professor of atmospheric and oceanic science at the University of Wisconsin–Madison, shows Earth’s oceanic conveyor belt, the Atlantic Meridional Overturning Circulation (AMOC), could collapse as carbon dioxide levels rise and lead to abrupt climate change.
The study, led by Liu’s former graduate student, Wei Liu (no relation), is published Jan. 4, 2017 in Science Advances. The collapse would occur about 300 years after Earth’s carbon dioxide levels double compared to 1990 levels.
Freshwater fish play a surprisingly crucial role in feeding some of the world’s most vulnerable people, according to a study published on October 24, 2016 in the Proceedings of the National Academy of Sciences.
