The Stellar Bar–Dark Matter Halo Connection in the TNG50 Simulations

The Astrophysical Journal
Stellar bars in disk galaxies grow as stars in near-circular orbits lose angular momentum to their environments, including their dark matter (DM) halo, and transform into elongated bar orbits.

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

The Impact of Local Stellar Radiation on Dwarf Galaxy Formation around Milky Way Analogs across Cosmic Reionization

The Astrophysical Journal
We explore the effect of local stellar radiation on the formation and evolution of dwarf galaxies around Milky Way (MW) analogs. Using five simulations from the Auriga project, both with and without local stellar radiation, we find that local stellar ...

Novel Liquid Biopsy in Gastrointestinal Cancers

Journal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Gastrointestinal (GI) cancers represent a significant global health burden, being among the leading causes of cancer‐related deaths. The prognosis for patients remains unsatisfactory, largely because most cancers are detected at advanced stages.

The Effect of Deep Brain Stimulation on Sleep and Cognition in Patients With Parkinson's Disease

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep–wake disturbances and cognitive decline are among the most common nonmotor symptoms of Parkinson's disease (PD). Deep brain stimulation (DBS) can successfully alleviate motor symptoms. However, the impact on sleep–wake disturbances and cognitive decline, and their interaction, is yet unclear.

DESI Emission-line Galaxies: Clustering Dependence on Stellar Mass and [O II] Luminosity

The Astrophysical Journal
We measure the projected two-point correlation functions of emission-line galaxies (ELGs) from the Dark Energy Spectroscopic Instrument One-Percent Survey and model their dependence on stellar mass and [O II ] luminosity.

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.
