Searching for GEMS: Discovery and Characterization of Two Brown Dwarfs Around M Dwarfs

The Astronomical Journal
Brown dwarfs bridge the gap between stars and planets, providing valuable insight into both planetary and stellar-formation mechanisms. Yet the census of transiting brown-dwarf companions, in particular around M-dwarf stars, remains incomplete. We report

Evolution of Employee Work Preferences Amidst COVID‐19: A Social Media Analysis

Human Resource Management Journal, EarlyView.
ABSTRACT Retaining and managing talent is critical for a firm's competitive advantage. While human resource management (HRM) literature suggests several configurations of bundles of ability(A), motivation(M), and opportunity(O) enhancing HRM practices for enhancing individual and firm performance, it fails to capture the dynamic contextual changes at ...

Insight Into Body Size Evolution in Aves: Based on Some Body Size–Related Genes

Integrative Zoology, EarlyView.
These findings provide new insights into the genetic determinants of body size evolutionary mechanisms in Aves. ABSTRACT Birds exhibit remarkable variations in body size, making them an ideal group for the study of adaptive evolution. However, the genetic mechanisms underlying body size evolution in avian species remain inadequately understood.

Comparing Grid Model Fitting Methodologies for Low-temperature Atmospheres: Markov Chain Monte Carlo versus Random Forest Retrieval

The Astrophysical Journal
The atmospheres of low-temperature stars, brown dwarfs, and exoplanets are challenging to model due to strong molecular features and complex gas and condensate chemistry.

A Novel GH Deficient Rat Model Reveals Cross‐Species Insights Into Aging

Aging Cell, EarlyView.
Mouse studies show disrupted GH signaling reduces body size, increases longevity, and improves health. We developed a CRISPR/Cas9 GH‐deficient rat model to address inconsistent rat evidence. GH‐deficient rats mirrored these findings, showing reduced body weight, increased body fat, enhanced insulin sensitivity, and altered gut microbiomes.

The rotation of brown dwarfs

, 2016
One of the characteristic features of low-mass stars is their propensity to shed large amounts of angular momentum throughout their evolution. This distinguishs them from brown dwarfs which remain fast rotators over timescales of gigayears. Brown dwarfs with rotation periods longer than a couple of days have only been found in star forming regions and ...
