Summary: This study assessed the changes in the redox status of military pilots during flight simulation conditions. The results showed that experienced pilots had significantly increased levels of GSH and reduced levels of TAC after flight simulation, while novice pilots had increased levels of CAT and TAC. No significant differences were observed in TBARS and PCs levels post-simulation. In addition, TAC and PCs levels were significantly lower in novice pilots compared to experienced pilots.

Summary: This study demonstrates that the majority of aircraft in single PPL-IFR ownership in the state with the largest count of single piston engine aircraft fail to complete 6 in-flight instrument approaches in 6 months. However, some of these aircraft/owners still choose to undertake flights in degraded visibility.

Summary: Chronic wounds, driven by hypoxia, present a challenge for medical professionals in the field of wound healing. Tissue reoxygenation therapy based on hyperbaric oxygen therapy (HBOT) has been used clinically, but the need for better oxygen-loading and -releasing strategies still remains. Combining various oxygen carriers with biomaterials has emerged as a promising therapeutic approach, with potential applications including the use of hemoglobin, perfluorocarbon, peroxide, and oxygen-generating microorganisms.

Summary: The black hole illusion (BHI) is a subtype of spatial disorientation that may have fatal consequences in aviation. This study examined the effect of BHI across different flight phases and found that multiple flight parameters were significantly impaired, with varying influences from the initial approach to the final touchdown.

Summary: This study compared the performance of touchscreens and mechanical devices in aircraft cockpits, finding that virtual keypads were faster for medium to large changes, while rotary knobs were fastest for small changes. Virtual keypads also had lower workload and discomfort compared to rotary knobs and drag-based widgets. Completion time was found to be the most important factor in tracking task performance.

Summary: Doping with rare-earth elements, a one-step hydrothermal method was used to prepare La-doped Ni-Sn oxide/reduced graphene oxide composite. The electrochemical performance of the composite was studied under different electrolyte conditions, and the LNSRG 2 composite showed good specific capacitance in 6M KOH electrolyte. An ASC device fabricated with LNSRG 2 and SRGO as positive and negative electrode materials, respectively, exhibited high energy density and good cyclic stability in 1M Na2SO4 electrolyte.

Summary: Flying places significant demands on pilots' perceptual and attentional capacities, with distractions such as cell phone conversations potentially leading to inattentional blindness. This study aimed to investigate the effects of diverting attentional resources away from flying tasks, revealing the potential risks of inattentional blindness for flight safety. Further research into reducing inattentional blindness would be beneficial for aviation safety.

Summary: This study aimed to compare inflight hypoxia symptoms with those experienced during training, finding that hypoxia symptoms appeared both during inflight events and training. The results suggest that the fading of individual memory highlights the continued need for hypoxia awareness training.

Summary: This study investigates the potential of different metal-centered organometallic phthalocyanine complexes as redox mediators for efficient Li-O-2 cells. The MPc-containing Li-O-2 cells exhibit improved performance, reduced polarization, and stable cyclability, with the introduction of superoxide species confirming their auto-oxygenation properties. Additionally, blended MPcs show synergistic effects in ambient air atmosphere.

Summary: NASA's Earth Science and Technology Office (ESTO) has developed a new uncooled multispectral thermal instrument to improve Earth observation from space. This instrument offers advantages in cost and size compared to cooled systems, but also presents challenges that need to be addressed. Through three airborne campaigns, the performance of the uncooled instrument was evaluated and found to exceed requirements. The results suggest that the uncooled system is a promising option for future space missions.
