Summary: In the last decade, the dominant view has been that subducted seamounts are weakly coupled and slip aseismically. However, recent observations have shown that the seamounts actually act as stationary buttresses while the surrounding region slides aseismically. This contradicts previous understanding and proves the weak asperity hypothesis false.

Summary: The mechanics of Dipteran thorax relies on a network of exoskeletal linkages to ensure coordinated wing and haltere movements, despite being powered by independent muscles. This system allows for precise phase-coordination between wings and halteres at high frequencies, even in the event of severe wing damage.

Summary: Astrocytes play a crucial role in maintaining brain homeostasis and respond to brain injury by undergoing morphological, proteomic, and transcriptomic changes. Traumatic brain injury (TBI) in children can lead to long-term health complications, yet the underlying pathophysiology is not fully understood. This review focuses on the immune role of astrocytes in pediatric TBI, exploring their contribution to local inflammatory cascades and recruitment of immune cells. Understanding the early changes in astrocytic phenotype and their impact on brain development can provide insights into neurological outcomes and potential therapeutic strategies.

Summary: We investigated the production of NH3 from H2 and N2 in a dielectric barrier discharge plasma reactor using different Co-based catalysts supported on Al2O3. The catalysts were characterized using various techniques and their performance was compared. CoLa/Al2O3 was found to be the best performing catalyst, but the differences in NH3 concentration, energy consumption, and production rate between the catalysts were limited under the same conditions. The plasma properties, such as power and current profile, varied significantly depending on the catalyst, indicating that the catalysts act as plasma modifiers.

Summary: TMEM176B plays a dual role in regulating immune responses, inhibiting effector immune responses in some cases while promoting immunity through antigen presentation in others. It may also have a role in regulating type 2 and 3 immunity, as well as dendritic cell biology and inflammasome activation.

Summary: This paper reports on the development of a model for a dual-channel protonic-ceramic fuel cell operating on ammonia fuel. The model takes into account the interactions of various physical and chemical processes in the cell, including heat conduction, flow, catalytic reactions, charge transfer, and ion transport. The model helps to understand the behavior of the fuel cell and provides insights into the partial ammonia decomposition and thermal control of the cell.

Summary: This study develops an innovative strategy to selectively produce linear alcohols from alkenes and CO2/H-2 through the regiocontrollable ability of the ligand. By using a bimetallic Rh-Ru catalyst with PTA ligand, high yields and regioselectivity of the desired alcohols are achieved, surpassing previous reports. The synergy of Rh and Ru, along with the elegant regulation of regioselectivity by PTA ligand, opens up a new pathway for industrial carbonylation with CO2.

Summary: The study demonstrates that K+-selective mutants lose selectivity filter stability under Na+ conditions without collapsing into a defined structure, and structural changes occur.
Compared to the non-selective wild-type NaK channel, the stronger link between the selectivity filter and the pore helix in K+-selective mutants reduces the ion-dependent conformational flexibility of the selectivity filter.

Summary: Cells contain membraneless compartments formed by liquid-liquid phase separation, including biomolecular condensates with complex morphologies. The size and structure of these condensates must be regulated for proper biological function. Amphiphilic, surfactant-like proteins may play a significant role in regulating the structure and function of biomolecular condensates.

Summary: This study reveals a previously unrecognized activity of tBID in mediating mitochondrial permeabilization independently of BAX and BAK, which has physiological relevance in immune response and cancer therapy. This novel function of tBID is dependent on a specific helix structure and can be blocked by anti-apoptotic proteins, providing potential implications for therapeutic intervention in bacterial infections and cancer treatment.

Summary: Transesophageal echocardiography (TEE) is the gold standard for detecting patent foramen ovale (PFO), and the bubble study with agitated saline contrast helps diagnose PFO. However, standard maneuvers may be challenging during TEE, and hypovolemia due to preprocedural fasting can affect PFO detection. Additional optimization measures, such as fluid replenishment with passive leg raise (PLR), can enhance PFO detection.

Summary: A 41-year-old man presented with recurrent micro thromboembolic strokes, which is unusual for his age, prompting further investigation. A rare plasminogen activator inhibitor-1 polymorphism associated with an increased risk of cerebrovascular thrombosis was discovered. This polymorphism has been less explored in recent medical literature and our case may stimulate future research.
