During its first two flybys of Mercury, the MESSENGER spacecraft acquired images confirming that pervasive volcanism occurred early in the planet's history. MESSENGER's third Mercury flyby revealed a 290-kilometer-diameter peak-ring impact basin, among the youngest basins yet seen, having an inner floor filled with spectrally distinct smooth plains. These plains are sparsely cratered, postdate ...

The maximum size of organisms has increased enormously since the initial appearance of life >3.5 billion years ago (Gya), but the pattern and timing of this size increase is poorly known. Consequently, controls underlying the size spectrum of the global biota have been difficult to evaluate. Our period-level compilation of the largest known fossil organisms demonstrates that maximum size increa...

Histiocytic necrotizing lymphadenitis, Kikuchi-Fujimoto's Disease (KFD), is a condition rarely associated with systemic lupus erythematosus (SLE). The diagnosis of KFD can precede, postdate or coincide with the diagnosis of SLE. Lymphadenopathy is a common clinical presentation of KFD and SLE, and is histologically indistinguishable in both conditions. We describe two cases of KFD associated wi...

Mercury’s Debussy Quadrangle (H14) lies between 0–90° E and 22.5–65° S. Here we use MESSENGER data to produce the first geological map of this quadrangle at a scale 1:3,000,000, based on linework completed 1:300,000. We distinguish crater units plains units. For compatibility with historic recent maps other Mercury quadrangles, global (Main Map), have made two versions map, craters classified a...

The relationship between previous use of oral contraceptives (OCs) and postdatism was investigated in 1496 women attending an antenatal clinic in a 7-month period in 1981. Postdatism was defined as spontaneous labor and delivery 14 or more days beyond the expected date of delivery as calculated by Naegele's rule (i.e., 9 months plus 1 week from the last menstrual period). 186 of the women rep...

Abstract In a 2021 contribution to Politics and Religion , Jesse Russell wrote that St. Thomas Aquinas “had decidedly illiberal view of government.” He says “advocates government in which the people are not given public liberty” did “prepare way for mixed monarchy English constitution.” But places rule moral law above politics, endorses participatory government, prioritizes reciprocal duties ra...

Diagenesis in the Permo-Triassic New Red Sandstone, Isle of Arran is characterized by early cementation hematite, clay, and calcite minerals, followed burial compaction, quartz, feldspar, pyrite cementation. Cataclasis post-dated quartz feldspar reduced grain pore aperture size deformed samples. Samples with cataclastic bands typically have 18% porosity 8.81 mD permeability on average. Whereas,...

[1] Phyllosilicates have previously been detected in layered outcrops in and around the Martian outflow channel Mawrth Vallis. CRISM spectra of these outcrops exhibit features diagnostic of kaolinite, montmorillonite, and Fe/Mg-rich smectites, along with crystalline ferric oxide minerals such as hematite. These minerals occur in distinct stratigraphic horizons, implying changing environmental c...

Purpose: The purpose of this research is to seek reasons for some videos going viral over YouTube (a type of social media platform). Methodology:Using YouTube APIs (Application Programming Interface) and Webometrics analyst tool, we collected data on about 100 all-time-most-viewed YouTube videos and information about the users associated with the videos. We constructed and tested an empirical m...
