The progression of basaltic-rhyolitic melt storage at Yellowstone Caldera.

Yellowstone Caldera is one of the largest volcanic systems on Earth, hosting three major caldera-forming eruptions in the past two million years, interspersed with periods of less explosive, smaller-volume eruptions. Caldera-forming eruptions at Yellowstone are sourced by rhyolitic melts stored within the mid- to upper crust. Seismic tomography studies have suggested that a broad region of rhyolitic melt extends beneath Yellowstone Caldera, with an estimated melt volume that is one to four times greater than the eruptive volume of the largest past caldera-forming eruption, and an estimated melt fraction of 6-28 per cent.

Cognate antigen engagement induces HIV-1 expression in latently infected CD4 T cells from people on long-term antiretroviral therapy.

Despite antiretroviral therapy (ART), HIV-1 persists in latently infected CD4 T cells, preventing a cure. Antigens drive the proliferation of infected cells, precluding latent reservoir decay. However, the relationship between antigen recognition and HIV-1 gene expression is poorly understood because most studies of latency reversal use agents that induce non-specific global T cell activation.

Triggering the 2022 eruption of Mauna Loa.

Distinguishing periods of intermittent unrest from the run-up to eruption is a major challenge at volcanoes around the globe. Comparing multidisciplinary monitoring data with mineral chemistry that records the physical and spatio-temporal evolution of magmas fundamentally advances our ability to forecast eruptions. The recent eruption of Mauna Loa, Earth's largest active volcano, provides a unique opportunity to differentiate unrest from run-up and improve forecasting of future eruptions.

Prevalence of hypertension and factors associated with the utilization of primary health care services for hypertension among hypertensive population aged 40 years and above in Pyin Oo Lwin Township, Myanmar.

Background: Utilization of hypertension services at primary health care levels has not been assessed at township level, since launching of PEN interventions in Myanmar. This study aimed to determine the factors associating with the utilization of primary health care services for hypertension among 40 years and above hypertensive population.

Methods: Community-based cross-sectional study was done in Pyin Oo Lwin Township, 2023.

Identifying bound compounds in non-extractable residues of pesticides in soil by 4-pool kinetic analysis.

This study explores the feasibility of identifying bound compounds in non-extractable residues (NERs) of pesticides in soil by 4-pool kinetic analysis. The 4-pools refer to parent compound, metabolites, NERs, and CO in C-labeled pesticide soil degradation studies. We discovered the following two characteristic 4-pool kinetic behaviors of formation of NERs: (1) if parent compound is bound as NERs, the metabolites (m(t) in % applied radioactivity (AR)) kinetically drive the evolution of CO only; and (2) if a metabolite (x) in a sequential degradation pathway is bound as NERs, m(t) is split into m(t) and m(t) at the metabolite (x) that is bound as NERs, which kinetically drive the formation of NERs and evolution of CO respectively.
