Chronic sleep loss is widespread and can cause deficits in vigilant attention. There are few practical biomarkers that can be used to assess the impact of chronic sleep loss on alertness and performance. Those that are available, such as tests of vigilant attention, cannot discriminate chronic sl...

Exposure to extreme high temperatures is a major constraint on global crop productivity, yet most large-scale assessments rely on fixed temperature thresholds that overlook regional variation in genetics, environment and management. Consequently, the temperature thresholds at which heat exposure ...

Anabaena, a nitrogen-fixing cyanobacterium from the Nostocaceae family, is a promising chassis for sustained space exploration. Using NEKO, this study surveys 2000 publications on Anabaena and summarizes the research, including systems biology, modeling, and potential space applications. Future r...

The elemental compositions of exoplanets encode information about their formation environments and internal structures. While volatile ratios such as carbon-to-oxygen (C/O) are used to trace formation location, the rock-forming elements-magnesium (Mg), silicon (Si), and iron (Fe)-govern interior ...

Infrared thermal imaging is used in defence, security cameras, fire detection, planetary science, driver assist capabilities, medical thermography, and other safety applications. Unfortunately, the lenses for infrared cameras are made from expensive or restricted materials such as germanium, sili...

Nature's fractal patterns should, in theory, exhibit some common characteristics as revealed by a number of space missions carried out in the neighborhood of Earth's space environment. Here, we show that the overall shape of the multifractal spectrum of galaxies resembles that of NASA's Voyager m...

Mobility and cognitive functions often decline concurrently in older adults, and may be particularly detrimental to walking in complex environments such as uneven terrain. Walking on uneven terrain particularly relies on visuospatial working memory to continuously adjust gait patterns; however, t...

Living donor kidney transplant often involves decisions that require complex recipient evaluation under substantial cognitive load. Large language models may augment clinician reasoning; however, their role in transplant assessment remains unexplored.We conducted a prospective, vignette-based stu...

Saline and freshwater wetlands store large amounts of carbon, which has driven interest in their role as nature-based climate solutions. Because these ecosystems can be both sinks and sources of carbon to the atmosphere as environmental conditions and human influence change, the net climate mitig...

Imaging is central to modern clinical medicine and advancing the level of care on exploration-class missions will require imaging capabilities to reduce medical risk. The NASA Informing Mission Planning via Analysis of Complex Tradespaces (IMPACT) tool suite was designed for exploration-class mis...

Thermophilic archaea synthesise cellular membranes composed primarily of isoprenoid glycerol dibiphytanyl glycerol tetraethers (iGDGTs). Cells can adjust the packing of their lipids by increasing cyclopentyl ring production, thereby decreasing membrane permeability and fluidity to maintain cellul...

The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein's general relativity (GR) in the high-velocity, strong-gravity regime and probe whether the remnant conforms to the Kerr metric. Upon perturbation, black holes emit...

Antibiotic resistance is a significant threat to global public health and can disproportionately affect low- and middle- income countries (LMICs). There is a lack of studies focusing on antibiotic resistance in coral reef regions and environmental reservoirs in Central America. This study followe...

The plans for sustained human presence on the Moon have increased interest in understanding the effects of lunar conditions on terrestrial biology. Plants play a vital role in space exploration, as they not only generate oxygen and remove carbon dioxide but also provide fresh food that can be ric...

Cognitive failure is a complex issue in the nursing work environment. This study aimed to examine the extent to which job content, perceived subjective workload, and job burnout predict cognitive failures among nurses working in the emergency departments (EDs).In this descriptive cross-sectional ...

Through repeated practice, humans acquire skills and develop a high level of expertise, but this learning process is sometimes long and costly. It may even be impossible to train in situ, although training in virtual environments can offer an alternative. Such supports also have the capacity to a...
