Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Are We Witnessing a Speciation Continuum? Evidence From Current and Past Gene Flow in the Genus Oritrophium s.s. (Asteraceae) From the Tropical High Andes

Molecular Ecology, EarlyView.
ABSTRACT Determining species boundaries is key for appropriately assessing biodiversity. However, the continuity of the speciation process makes delimiting species a difficult task, especially for recently diverged taxa. Furthermore, past introgression may leave traces that result in reticulate evolutionary patterns, challenging the estimation of ...

ZW and XY Sex Chromosomes Drive Rapid and Distinctive Evolution of Sex‐Biased Gene Expression

Molecular Ecology, EarlyView.
ABSTRACT Cichlids are a textbook model system of adaptive radiation and a fascinating example of rapid sex chromosome evolution. Yet in these fish, as in most other taxa, the mechanisms causing sex chromosome turnover and the subsequent impact thereof are unknown.

Atrial Arrhythmias in Cardiac Sarcoidosis—Case Presentation and Systematic Review

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Sarcoidosis is a rare idiopathic, multiorgan disease with clinical cardiac involvement in approximately 5% of cases. Diagnosis and management of cardiac sarcoidosis (CS) have mainly focused on impaired LV function, ventricular arrhythmias, and atrio‐ventricular conduction disease.
