"Scientists Uncover Origins of Earth's Indestructible Continents"

Researchers at Penn State have discovered that ancient weathering processes played a crucial role in the formation and stabilization of Earth's cratons, the most indestructible parts of the planet's crust, during the Neoarchaean era. This weathering released heat-producing elements that, when buried and heated, led to the differentiation and stabilization of the continental crust, explaining the resilience of cratons and their importance in hosting valuable mineral deposits.

Poverty and Racism's Impact on Health: The 'Weathering' Case

Marginalized people in the US suffer nearly constant stress from living with poverty and discrimination, which damages their bodies at the cellular level and leads to increasingly serious health problems over time, according to public health researcher Arline Geronimus. She coined a term for this chronic stress — "weathering" — which "literally wears down your heart, your arteries, your neuroendocrine systems, ... all your body systems so that in effect, you become chronologically old at a young age." Marginalized communities have worse health outcomes than the overall population due to chronic stress, which is not the same as middle- and upper-class "stress."
