A hitchhiker's guide to modern, practical cyanobacterial taxonomy
Journal of Phycology, EarlyView.Abstract There has been an explosion of new Cyanobacterial taxa described within the last two decades. Cyanobacteria exhibit incredible ecological versatility and morphological variability, and thousands of species have already been described using “traditional” approaches (e.g., morphological features).

Detection of a Spatially Extended Stellar Population in M33: A Shallow Stellar Halo?
The Astrophysical JournalWe analyze the outer regions of M33, beyond 15 kpc in projected distance from its center, using Subaru/Hyper Suprime-Cam multicolor imaging. We identify red giant branch (RGB) stars and red clump (RC) stars using the surface-gravity-sensitive NB515 ...

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.

Visit Nearby Halo Substructures Using LAMOST DR9 MRS Data
The Astrophysical JournalBased on the LAMOST DR9 Medium Resolution Spectra (MRS) catalog, combined with astrometries from Gaia DR3, we conducted an investigation into the substructures in the stellar halo to obtain their chemical and kinematic information.

The Shape of the Chameleon Fifth-Force on the Mass Components of Galaxy Clusters
UniverseIn the context of chameleon gravity, we present a semi-analytical solution of the chameleon field profile in an accurately modelled galaxy cluster’s mass components, namely the stellar mass of the Brightest Cluster Galaxy (BCG), the baryonic mass in ...

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.

The fall of the Haag (LL4‐6) chondrite breccia—Just 8 years after the nearby fall Stubenberg (LL6)
Meteoritics &Planetary Science, EarlyView.Abstract On October 24, 2024, an impressive fireball was visible over Austria. After the possible strewn field was calculated, the first sample of the Haag meteorite, with a mass of 8.76 g, was discovered on November 2, 2024, 8 days after the fireball event. Four more samples were found afterward putting the total sample mass at about 151 g.
