Summary: After assessing the impact of hepatitis A vaccine in Alaska Native persons, it was found that only 6 cases of hepatitis A were identified from 1996 to 2018, all in unvaccinated adults. The study highlights the importance of achieving sufficient vaccination coverage over time to protect populations against hepatitis A.

Summary: Comprehensive observations of surface wave anisotropy are conducted across Alaska and the Aleutian subduction zone to improve understanding of its tectonics, mantle dynamics, and earthquake risk. Using data from various sources, including earthquakes and ambient noise, researchers create tomographic maps that provide insights into the crustal and uppermost mantle structure of the region.

Summary: The genus Phaeorrhiza is reported as new for the Chinese lichen biota, with two species characterized by squamulose to subfoliose thallus and Beltraminia-type ascospores. P. nimbosa has cryptolecanorine to eulecanorine apothecia, while P. sareptana var. sphaerocarpa has lecideine apothecia.

Summary: After the purchase of Alaska from Russia, Alaska Native lands were legally vulnerable to Congress' extinguishment of ancestral land rights. The Alaska Native Claims Settlement Act (ANCSA) provided a means for Alaska Natives to secure their land rights, but erosion caused by climate change now threatens the allocated lands. In our article, we propose an erosion monitoring tool and present case studies to illustrate the significant loss of cultural lands, urging tribal entities to adopt this method for protecting Alaska Native land rights.

Summary: The study reports the chronology of moraine crests in the western Alaska Range, indicating the culmination of the regional Last Glacial Maximum around 21-19 ka. The retreat of glaciers in Alaska experienced periods of steady recession and accelerated retreat, influenced by various climate factors. The findings suggest that glacier retreat in Alaska was sensitive to factors such as warming, global warming, and ocean circulation.

Summary: The interpretation of seismic data from the U.S. Chukchi shelf reveals the occurrence of four tectonic events in the last 400 million years, resulting in distinct inherited structures. These events include the formation of a fold-and-thrust belt, the development of the Hanna Trough, deep thrusting in the North Chukchi high, and Cenozoic extension and strike-slip faulting in the Hanna Trough.

Summary: The study examines the generation mechanism of earthquake infrasound and demonstrates the potential for monitoring infrasound to constrain earthquake source properties. Different types of repeating infrasound are identified, along with the influence of various earthquake focal mechanisms on infrasound observations.

Summary: A remote sensing-derived lake ice phenology database covering all lakes in Alaska from 2000 to 2019 was constructed to analyze the trends of earlier breakup and later freezeup of lake ice in the region. The dataset showed significant trends towards earlier or later ice breakup and freezeup for various lakes, with most significant trends observed in lakes north of the Brooks Range. This dataset contributes to the understanding of interactions between lake processes and climate change, supporting research on biogeochemical, limnological, and ecological regimes in Alaska and pan-Arctic regions.

Summary: Terrane accretion leads to complex slip histories in lithospheric-scale fault systems. This study in the Alaska Range suture zone documents the geological evolution of reactivated shortening structures and metamorphic rocks, revealing the linkage between different upper crustal structures through the lithosphere. Detrital zircon U-Pb age spectra highlight distinct metasedimentary belts and a connection to the Wrangellia composite terrane, with the Valdez Creek fault playing a key role in reactivating structures within the suture zone.

Summary: Some of the largest climatic changes in the Arctic have been observed in Alaska and the surrounding marginal seas. In the past half century, Alaska has experienced a broad increase in near-surface air temperature, especially during winter, spring, and autumn. Precipitation has also increased and is strongly related to temperature-sea ice feedbacks.

Summary: The study revealed a 26% increase in LRTI rates among adult AI/AN residing in AK compared to a 38% decrease in rates among AI/AN residing in non-AK, likely due to factors such as tobacco use and crowding. Strategies to reduce LRTI in AI/AN adults are necessary.

Summary: Using Pn tomography with coordinate rotation, a new Pn velocity and anisotropy model was obtained for imaging in Alaska and adjacent areas. The study found correlations between observed Pn velocities and local geological structures, as well as low velocities beneath the Aleutian volcanic arc potentially revealing plate dehydration-related partial melting. A slab tear was suggested by the separation of low velocities by a high-velocity anomaly, indicating complex deformation beneath Alaska and adjacent areas.

Summary: The study discusses the impact of dietary fibre supplementation on colorectal cancer risk among Alaska Native people. Methods include baseline assessments, colonoscopy, randomization to fibre supplement or placebo, and evaluation of biomarkers. The research aims to inform on the effects of fibre supplements on mucosal inflammation, proliferative markers, and microbiome diversity.

Summary: Fairbanks, Alaska experiences poor air quality in winter due to atmospheric inversions, local emissions, and unique chemistry caused by cold and dark conditions. This study focuses on the high concentrations of fine particle hydroxymethanesulfonate (HMS) and its links to inorganic sulfate and organic mass in pollution episodes, highlighting the formation of air pollution in cold and humid atmospheres.
