Global Lunar Crater Density Using Buffered Nonsparseness Correction

open access: yesThe Planetary Science Journal
The density of craters on a planetary surface directly relates to the age of the surface. As the surface ages, however, craters can be erased by subsequent large impacts via direct overprinting, known as geometric crater obliteration.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Impact provenance and age of a unique basalt found in Apollo 12 regolith

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Basaltic sample 12032,366‐18 from the Apollo 12 landing site is distinct among basalts collected at this site, other Apollo landing sites, and lunar meteorites in terms of its age, bulk rock composition, and isotopic composition. We present new Pb isotopic data obtained by in situ Secondary Ion Mass Spectrometry on multiple mineral phases in ...

Associations Between Body Composition and Metabolic Health in Children With Obesity

open access: yesMaternal &Child Nutrition, EarlyView.
ABSTRACT Childhood obesity is an increasing public health problem with heterogeneous metabolic health outcomes. In children, distinguishing differences in body composition between individuals with metabolically healthy obesity (MHO) and those with metabolic syndrome (MS) may be useful for understanding the impact of body composition on metabolic health.

The Ramadan Gambit: The Impact of Fasting on Cognitive Performance

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT More than 2 billion people participate annually in Ramadan fasting, making its potential effects on cognitive performance important for workplaces, education and high‐stakes decision‐making. We study these effects in tournament chess, an incentivised, real‐world cognitive task in which move quality can be evaluated objectively by a strong ...

The role of antibiotics in preventing surgical complications in periodontology and implant dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract Antibiotics are commonly prescribed in periodontal and implant surgeries, either before, during or after surgery, to prevent postoperative infection and reduce early implant failure. However, the potential benefits may be undermined by the risks of resistance and sensitization, thus requiring a strict indication for prescription.

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.
