Metallicity and α-abundance for 48 Million Stars in Low-extinction Regions in the Milky Way
We estimate ([M/H], [ α /M]) for 48 million giants and dwarfs in low-dust extinction regions from the Gaia DR3 XP spectra by using tree-based machine learning models trained on APOGEE DR17 and a metal-poor star sample from Li et al.

The merger that led to the formation of the Milky Way’s inner stellar halo and thick disk [PDF]
The assembly process of our Galaxy can be retrieved using the motions and chemistry of individual stars. Chemo-dynamical studies of the nearby halo have long hinted at the presence of multiple components such as streams, clumps, duality and correlations between the stars' chemical abundances and orbital parameters.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Disk Heating, Galactoseismology, and the Formation of Stellar Halos
Deep photometric surveys of the Milky Way have revealed diffuse structures encircling our Galaxy far beyond the “classical” limits of the stellar disk. This paper reviews results from our own and other observational programs, which together suggest that,

Build up of the Milky Way's stellar halo
Our understanding of the formation and evolution of the Milky Way is undergoing a revolution after Gaia's measurements. We have discovered a dominant population of radially biased stars (`Gaia-sausage' or `Gaia-Enceladus') which is attributed to a significant event in the history of the Milky Way, a merger with a relatively massive dwarf galaxy .

This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

The Rapid Formation of the Metal-poor Milky Way
Our understanding of the assembly timeline of the Milky Way has been transforming along with the dramatic increase in astrometric and spectroscopic data available over the past several years.

Formation of Milky Way-type stellar haloes in a Λ-CDM cosmology
Recent observations suggest that the Milky Way stellar halo has a ‘dual nature’, meaning that both dissipational and dissipationless processes play a role in its build-up.

ELVES. III. Environmental Quenching by Milky Way–mass Hosts
Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way–mass groups.
