Summary: The study analyzed the relationship between unconventional natural gas development and acute myocardial infarction using New York's ban on hydraulic fracturing as a natural experiment. The results showed that cumulative unconventional natural gas development is associated with increased AMI hospitalization rates among middle-aged men, older men, and older women, as well as increased AMI mortality among middle-aged men. Bans on hydraulic fracturing may be protective for public health in terms of cardiovascular risks.

Summary: The study found that unconventional natural gas development is associated with increased rates of acute myocardial infarction (AMI) hospitalization and mortality, particularly affecting middle-aged men and the elderly. Therefore, increased awareness of the cardiovascular risks of unconventional natural gas development and scaled-up AMI prevention efforts are needed to protect public health.

Summary: The impact of unconventional oil and gas (UOG) development on freshwater ecosystems is not fully understood. This study used a laboratory experiment and a survey study to investigate the effects of UOG development on microbial biodiversity and function. The results showed that UOG development alters water temperature, chemistry, sediment CO2 production, and microbial community biodiversity in streams. There were consistent changes in the relative abundance of bacterial taxa, suggesting that microorganisms could be used as indicators of environmental changes associated with UOG development. The observed impacts on microbial community composition and carbon cycling could have cascading effects on stream health and broader ecosystem function.

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 June 2019, China changed its unconventional natural gas subsidy policy to a competitive mode to reduce subsidy pressure and focus on specific projects. Through a comparative analysis of old and new policies and data of three types of unconventional natural gas, the impact of the new policy on shale gas, tight gas, and CBM is revealed.

Summary: Exposure to a mixture of UOG-associated chemicals can have negative impacts on the immune system, leading to alterations in T-cell subsets. These impacts vary between different disease models and genders, suggesting that direct exposure to these chemicals may disrupt the adult immune system.

Summary: This research examines media portrayals of unconventional oil and gas development's (UOGD) economic and environmental impacts. It reveals that selective attention to media coverage of the impacts can influence issue attitudes. The study also finds that political ideology plays a role in driving such attention, and that the attention given to different types of impacts predicts public support for UOGD.

Summary: Analysis of crude oil and shale samples in the Nanpu sag revealed the characteristics and origins of oil and gas, showing that heavy oil is a product of biodegradation and oxidation. Different types of crude oil sourced from different formations are distributed in various structural belts in the region. Discovery of natural gas primarily as dissolved gas in oil and free gas.

Summary: This research provides a comprehensive analysis of lightweight proppants. It covers the research advances made on lightweight proppants in both scientific literature and commercial proppants manufacturers. The paper discusses three varieties of lightweight proppants: hollow/porous proppants, surface-modified proppants, and proppants derived from low-density materials. Field application of lightweight proppant in scale inhibition, gravel packing, and hydraulic fracturing is also summarized. Furthermore, the research highlights the future research directions and obstacles of lightweight propellants.
