Signature of a Dark Ultracompact Dwarf Galaxy Transiting the Milky Way Disk
The Astrophysical Journal LettersWe report the discovery of a vertical velocity anomaly in the stellar component of the Galactic disk, consistent with the impact of a dark, ultracompact dwarf galaxy (UCD)-sized object plunging into the Milky Way.

Advanced Materials, EarlyView.The lipid droplet inhibitor (LDI), templated with large‐pore mesoporous silica and functionalized with PKCα C1A and lipase, targets lipid degradation in fatty liver. The LDI maintains stable association with lipid droplets, thereby suppressing their formation and expansion.

The ∞ Galaxy: A Candidate Direct-collapse Supermassive Black Hole between Two Massive, Ringed Nuclei
The Astrophysical Journal LettersWe report the discovery of an unusual z = 1.14 object, dubbed the ∞ galaxy, in JWST imaging of the COSMOS field. Its rest-frame near-IR light is dominated by two compact nuclei with stellar masses of ∼10 ^11 M _⊙ and a projected separation of 10 kpc ...

Advanced Materials, EarlyView.Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

AT2021aeuk: A Repeating Partial Tidal Disruption Event Candidate in a Narrow-line Seyfert 1 Galaxy
The Astrophysical JournalA black hole (BH) can tear apart a star that ventures within its tidal radius, producing a luminous flare as the stellar debris falls back, known as a tidal disruption event (TDE).

Advanced Materials, EarlyView.Electret‐style organic thin‐film transistors are evaluated for synchrotron X‐ray dosimetry at ultra‐high dose rates, showing promising performance and agreement with standard detectors. XPS and NEXAFS reveal radiation‐induced oxidation and Fermi level shifts in pentacene and polystyrene, correlating with reduced charge carrier mobility and providing ...

Light and hyper nuclei formation at sNN= 3 GeV Au+Au collisions using Wigner coalescence approach
Physics Letters BThe production of light nuclei and hyper-nuclei in heavy-ion collisions, particularly at high baryon density, is crucial for understanding the dynamical evolution of the collision system and exploring the internal state of nuclear matter of compacted ...
