Summary: The environmental implications of unconventional oil and gas extraction are only recently starting to be systematically recorded. Our research shows the utility of microbial communities paired with geochemical markers to build strong predictive random forest models of unconventional oil and gas activity and the identification of key biomarkers.

Summary: In the town of Nantucket, Massachusetts, we conducted drag sampling at 12 study sites and found that blacklegged ticks were common in moist deciduous woodlands and rare in open grasslands. Pathogen testing revealed that around 10-20% of blacklegged nymphs were infected with the bacterium that causes Lyme disease. Lone star ticks were common on Tuckernuck Island and rare on Nantucket Island. Tick-borne diseases and tick-induced red meat allergy pose significant threats to public health.

Summary: Rate transient analysis was conducted on four MIP wells in Marcellus Shale Energy and Environment Laboratory to study the impact of reservoir and fluid properties, production rates, wellhead pressures, and hydraulic fracturing data on the well performance. The study employed various analysis techniques and found that a log-log plot of pseudo-normalized gas flow rate vs. pMBT is the most promising for flow regime identification. The relative performance of the shale gas wells was assessed using A root k per number of fracture clusters as a more reliable measure.

Summary: This study investigates the impacts of unconventional shale gas development on aquatic ecosystems and finds that it has weak negative effects on water quality and benthic macroinvertebrates. The impacts are particularly significant in the year with the most intense shale gas development activity, with downstream areas being affected more prominently.

Summary: The study found that honey bees were exposed to a variety of pesticides, with most detections occurring at levels predicted to be of low risk to colonies. High risk samples usually contained one of 12 different insecticides or varroacides, while exposures predicted to be low-risk were nevertheless associated with colony morbidity.

Summary: This study found a 4.5-fold increase in SARS-CoV-2 seroprevalence from Fall 2020 to February 2021 in Allegheny County, Pennsylvania, due to increased incidence of both natural disease and vaccination. The neutralization titer was significantly correlated with RBD titer but not with N titer. In the February cohort, higher median income and white race were associated with serological findings consistent with vaccination.

Summary: The study suggests that school absenteeism data can help predict influenza transmission, especially among K-5 students. ILI-specific absences performed better than all-cause absences in some years. These seasonal models can serve as a useful tool for influenza surveillance.

Summary: Flathead Catfish have been introduced into Atlantic Slope drainages from Florida to Pennsylvania, quickly establishing populations. Surveys show that the abundance of Flathead Catfish decreases as distance from the initial detection point increases, exhibiting an upstream expansion pattern. Ongoing and future targeted surveys will help understand changes in distribution and abundance of Flathead Catfish in these systems.

Summary: Unconventional hydrocarbon production has raised environmental concerns due to its potential risks to water resources. This study conducts an environmental isotopes analysis and evaluates other parameters to establish a baseline for the groundwater and riverine water systems in the Sao Francisco Basin, Brazil. The findings support stakeholders in monitoring and managing the unconventional gas industry.

Summary: Borehole geophysical logging and long-term pump test data analysis were used to characterize the aquifer system in Precambrian metagranite in Fauquier County, Virginia. Results suggest that water-bearing fractures in the metagranite are primarily recharged by groundwater stored in the regolith. Testing assumptions about a recharge boundary sourced by the regolith using a simple groundwater flow model further supported this conclusion.

Summary: This study evaluates the impact of different pressure drawdown strategies on long-term production and economic outcomes. The results show that lower pressure drawdown can maximize cumulative gas production, while rapid drawdown can achieve the highest profitability. Machine learning prediction capabilities are effective for generating multiple scenario forecasts, providing critical insights for decision-making in unconventional oil and gas operations.

Summary: This study analyzes the nature of the Welsh ethno-linguistic community in Clearfield County, Pennsylvania during the late 19th and early 20th centuries. It suggests that Welsh ethnic integrity was initially maintained due to linguistic ability, occupational specialization, and vibrant cultural institutions, but was ultimately undermined by forces of acculturation and factors such as high levels of exogamy and the cessation of immigration from Wales.

Summary: The study found that male weight concerns tend to focus on shape and muscularity rather than thinness. Some males have concerns about weight and disordered eating behaviors during adolescence and young adulthood. Additionally, concerns about muscularity and the use of muscle-enhancing products have an impact on body image and weight control among males.

Summary: This study analyzed data from the Growing Up Today Study in the U.S. and found that different types of maltreatment during childhood and adolescence had a significant impact on the risk of developing eating disorder behaviors in young adulthood. Women had the highest risk in the sexual abuse group, while men had the highest risk in the physical and emotional abuse group.

Summary: This article uses a task-based interview method to explore undergraduate students' understanding of text data. The study reveals that students use three types of features (function, content, and form) when classifying headlines. The analysis shows that this sequence of activities engages participants in thinking at both the human-perception and computer-extraction levels, and helps them conceptualize the connections between the two.

Summary: Geometry of the ear canal is important for understanding sound flow, but measurements of its geometry are lacking. This study developed methods to measure ear canal geometry using CT images and found that older adults have larger canal areas than previously assumed. The canal areas varied systematically with age cohort, with young adults having an average area of 44 mm² and older adults having a significantly larger average area of 69 mm². The measurements of canal areas at different locations and canal length were also reported.
