Continuous evolution of compact protein degradation tags regulated by selective molecular glues.

Conditional protein degradation tags (degrons) are usually >100 amino acids long or are triggered by small molecules with substantial off-target effects, thwarting their use as specific modulators of endogenous protein levels.

Endogenous proteins tagged in-frame with SD40 using prime editing are degraded by otherwise inert PT-179.

Scalable Multipollutant Exposure Assessment Using Routine Mobile Monitoring Platforms.

Introduction: The absence of spatially resolved air pollution measurements remains a major gap in health studies of air pollution, especially in disadvantaged communities in the United States and lower-income countries. Many urban air pollutants vary over short spatial scales, owing to unevenly distributed emissions sources, rapid dilution away from sources, and physicochemical transformations. Primary air pollutants from traffic have especially sharp spatial gradients, which lead to disparate effects on human health for populations who live near air pollution sources, with important consequences for environmental justice.
