Multifeature analyses of vascular cambial cells reveal longevity mechanisms in old Ginkgo biloba trees
This article investigates age-related changes in Ginkgo biloba trees to learn more about the molecular and metabolic mechanisms underlying their longevity. The results revealed that long-lived trees have evolved compensatory mechanisms to maintain a balance between growth and aging processes.

Occupational gender segregation and economic growth in United States local labor markets, 1980 through 2010
This article explores the barrier that gender segregation posses to the exchange of diverse ideas between women and men workers in the United States. The author uses fixed effects regression models to examine the relationship between labor market levels of segregation and economic growth from 1980 and 2010. Results from this study suggest that gender equity is a vital ingredient in the economic development of local United States labor markets.

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds
This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Effects of UV Stabilizers on Polypropylene Outdoors
This article looks at hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. The combination of HALSs and nano-ZnO stabilizers makes the PP films harder—which is important for some PP applications, such as toy manufacturing.

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses
Describes study which assessed the upper (CTmax) and lower (CTmin) thermal limits of three freshwater macroinvertebrate taxa with restricted low elevation distribution (20 m a.s.l.) and three taxa restricted to upper elevations (480 and 700 m a.s.l.) in the Magellanic sub-Antarctic ecoregion of southern Chile, and argues that their low tolerance to temperature increase can make them useful as indicators of thermal alteration in their habitats.

School-Based Sedentary Behavior, Physical Activity, and Health-Related Outcomes among Hispanic Children in the United States: A Cross-Sectional Study
The article highlights a study meant to examine the relationships between school-based sedentary behavior, physical activity, and health-related outcomes, including cardiorespiratory fitness, weight status, and health-related quality of life (HRQOL) among Hispanic children. Sedentary behavior was negatively correlated with cardiorespiratory fitness and HRQOL but positively associated with weight status. MVPA was positively correlated with cardiorespiratory fitness and HRQOL, but negatively associated with weight status and sedentary behavior. Multiple regressions demonstrated that sedentary behavior significantly predicted cardiorespiratory fitness and weight status, whereas MVPA significantly predicted HRQOL.

Peripheral Circulating Exosomal miRNAs Potentially Contribute to the Regulation of Molecular Signaling Networks in Aging
This article aims to understand some of the causes of aging and the underlying mechanisms that may lead to interventions that could reverse certain aging processes and slow development of aging-related diseases. People are living longer than ever. Consequently, they have a greater chance for developing a functional impairment or aging-related disease, such as a neurodegenerative disease, later in life.

Underlying Ossification Phenotype in a Murine Model of Metastatic Synovial Sarcoma
This article presents the analysis of genetic mouse models of synovial sarcoma to determine the extent of ossification in the tumors and its relationship with morbidity. The authors noted higher ossification within their metastatic mouse model of synovial sarcoma. Their conclusion is that both metastasis and ossification are dependent on time, but that they are independent of one another.
