True Pair-instability Supernova Descendant: Implications for the First Stars’ Mass Distribution
The Astrophysical Journal LettersThe initial mass function (IMF) of the first Population III (Pop III) stars remains a persistent mystery. Their predicted massive nature implies the existence of stars exploding as pair-instability supernovae (PISNe), but no observational evidence had ...

Precise Asteroseismic Ages for the Helmi Streams
The Astrophysical JournalThe Helmi streams are remnants of a dwarf galaxy that was accreted by the Milky Way and whose stars now form a distinct kinematic and chemical substructure in the Galactic halo. Precisely age-dating these typically faint stars of extragalactic origin has

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Milky Way’s Metal-poor Stars Display Chemical Transition near the Solar Radius
The Astrophysical Journal LettersThe metal-poor stars of a galaxy offer insights into that galaxy’s early formation processes and accretion history. Here, we investigate whether the metal-poor stars of our Milky Way Galaxy exhibit any characteristic trends in Galactocentric distance ...
