Ambient Mercury Observations near a Coal-Fired Power Plant in a Western U.S. Urban Area

open access: yesAtmosphere, 2019
We report on the continuous ambient measurements of total gaseous mercury (TGM) and several ancillary air quality parameters that were collected in Colorado Springs, CO. This urban area, which is located adjacent to the Front Range of the Rocky Mountains,

The Diurnal Path to Persistent Convective Self‐Aggregation

open access: yesJournal of Advances in Modeling Earth Systems, 2022
Clustering of tropical thunderstorms constitutes an important climate feedback because it influences the radiative balance. Convective self‐aggregation (CSA) is a profound modeling paradigm for explaining the clustering of tropical oceanic thunderstorms.

Correlates of testosterone change as men age

open access: yesThe Aging Male, 2022
Objective: The literature on testosterone (T) in men reports diverse correlates of T, some with minimal empirical support and most with little indication of how they change with advancing age. We test eight putative correlations across age.

Chloroplast Signaling Gates Thermotolerance in Arabidopsis

open access: yesCell Reports, 2018
Summary: Temperature is a key environmental variable influencing plant growth and survival. Protection against high temperature stress in eukaryotes is coordinated by heat shock factors (HSFs), transcription factors that activate the expression of ...

Differential Diel Translation of Transcripts With Roles in the Transfer and Utilization of Iron-Sulfur Clusters in Arabidopsis

open access: yesFrontiers in Plant Science, 2018
Iron-sulfur (Fe-S) clusters are evolutionarily ancient ubiquitous protein cofactors which have mostly catalytic functions but can also have structural roles.

Nighttime Light Hurts Mammalian Physiology: What Diurnal Rodent Models Are Telling Us

open access: yesClocks & Sleep, 2021
Natural sunlight permits organisms to synchronize their physiology to the external world. However, in current times, natural sunlight has been replaced by artificial light in both day and nighttime.

Examination of the Daily Cycle Wind Vector Modes of Variability from the Constellation of Microwave Scatterometers and Radiometers

open access: yesRemote Sensing, 2021
Offshore of many coastal regions, the ocean surface wind varies in speed and direction throughout the day, owing to forcing from land/sea temperature differences and orographic effects.

Effects of the Light/Dark Phase and Constant Light on Spatial Working Memory and Spine Plasticity in the Mouse Hippocampus

open access: yesCells, 2023
Circadian rhythms in behavior and physiology such as rest/activity and hormones are driven by an internal clock and persist in the absence of rhythmic environmental cues.
