Centimeter‐Scale Self‐Assembling Tendon Organoids Drive Tissue Regeneration

Advanced Science, EarlyView.
Centimeter‐scale tendon organoids are engineered by mimicking the extracellular matrix and optimizing chemical cues to guide tendon stem/progenitor cells. These large, self‐assembling constructs overcome conventional size limitations and exhibit enhanced tenogenic differentiation, extracellular matrix production, and mechanical resilience. Their tissue‐

King and Cochrane: The technological treadmill and racial inequity in US agriculture

Applied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.

Quantifying the land‐use change due to soybean‐based biodiesel in the United States

Applied Economic Perspectives and Policy, EarlyView.
Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...
