SDSS J100711.74+193056.2: A Candidate Common Motion Substellar Companion to the Nearest B-type Star Regulus

open access: yesThe Astronomical Journal
The L9 dwarf SDSS J100711.74+193056.2 is situated 7 $\mathop{.}\limits^{^\circ }$ 5 north of the nearest B-type star Regulus ( d  = 24.3 ± 0.2 pc), part of a stellar quadruplet.

Animal models of lung cancer: Phenotypic comparison of different animal models of lung cancer and their application in the study of mechanisms

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Grafts used to construct lung cancer animal models come from various sources, primarily cell lines, patient‐derived tumor tissues, and circulating tumor cells. Based on the sources of grafts and research objectives, lung cancer animal models can be categorized into several types: chemical‐induced models, orthotopic transplantation models, heterotopic ...

Atmospheric Abundances and Bulk Properties of the Binary Brown Dwarf Gliese 229Bab from JWST/MIRI Spectroscopy

open access: yesThe Astrophysical Journal Letters
We present JWST/Mid Infrared Instrument (MIRI) low-resolution spectroscopy (4.75–14 μ m) of the first known substellar companion, Gliese 229Bab, which was recently resolved into a tight binary brown dwarf.

Midlife Steroid‐Binding Globulin Levels and In Vivo Neuroimaging Measures of Tau in Older Men and Women

open access: yesAnnals of Neurology, EarlyView.
Objective In men and women, sex steroid hormones have been associated with increased risk of Alzheimer's disease (AD) dementia. We aimed to investigate the influence of midlife testosterone and sex hormone binding globulin (SHBG) levels on later‐life in vivo markers of β‐amyloid (Aβ) and tau deposition in clinically healthy older men. Methods This time‐

The Sonora Substellar Atmosphere Models. III. Diamondback: Atmospheric Properties, Spectra, and Evolution for Warm Cloudy Substellar Objects

open access: yesThe Astrophysical Journal
We present a new grid of cloudy atmosphere and evolution models for substellar objects. These models include the effect of refractory cloud species, including silicate clouds, on the spectra and evolution.

Design of Fluorine‐Free Weakly Coordinating Electrolyte Solvents with Enhanced Oxidative Stability

open access: yesAngewandte Chemie International Edition, EarlyView.
Incorporation of silicon is systematically explored as a sustainable strategy to design weakly solvating electrolytes for lithium‐based batteries. After identifying a promising molecular structure via computational screening, coordination spheres and their correlation with electrochemical key performance indicators are compared between electrolyte ...
