Futures of Transit Work: Contesting Devaluation and Neoliberal Automation in Bus Transit
ABSTRACT Being a bus operator has long meant access to middle class wages, quality benefits, and union membership, forms of security increasingly rare amid growing precarity. But transit is in trouble. In the wake of the COVID‐19 pandemic and decades of disinvestment, bus operators face mounting time pressure, frequent violence, and eroding job ...

Ecologization Is Not a Metaphor: Museums in the Web of Life
ABSTRACT This article documents and critiques emerging accounts of museum “ecologization”. Drawing on political ecology, materialist theory, and contemporary museum practice, we challenge dominant frameworks of ecological modernization and advocate for a more critical understanding of museums in the web of life.

Noble gases and nitrogen in material from asteroid Bennu
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

Static recrystallization of shocked calcite in Ries impact breccias
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.
