The Astrophysical JournalWe investigate the emergence phase of young star clusters in the nearby spiral galaxy NGC 628. We use JWST NIRCam and MIRI observations to create spatially resolved maps of the Pa α 1.87 μ m and Br α 4.05 μ m hydrogen recombination lines, as well as 3.3 ...

Wolf - Rayet Stars in H II Regions [PDF]
Monthly Notices of the Royal Astronomical Society, 1971 A catalogue of WR stars coincident with H II regions is presented. Approximately 44 per cent of the WR stars surveyed are found to be 'possibly' associated with nebulosity while association is considered to be 'probable' for 25 per cent of the cases.

Star formation associated with a large-scale infrared bubble
, 2014 Using the data from the Galactic Ring Survey (GRS) and Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE), we performed a study for a large-scale infrared bubble with a size of about 16 pc at a distance of 2.0 kpc. We present the 12CO J=1-

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Expansion Signatures in 35 H II Regions Traced by SOFIA [C II] Emission
The Astrophysical JournalWe analyze the expansion signatures of 35 H II regions mapped in [C II ] 158 μ m emission by the Stratospheric Observatory for Infrared Astronomy. The [C II ] emission primarily traces photodissociation regions (PDRs) at the transition between ionized ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The Astrophysical JournalWe present the variations in far-ultraviolet (FUV) and H α star formation rates (SFR), SFR _UV and SFR _H _α , respectively, at subkiloparsec scales in 11 galaxies as part of the Deciphering the Interplay between the Interstellar Medium, Stars, and the ...

, 2018 Massive stars are the main objects that illuminate H II regions and they evolve quickly to end their lives in core-collapse supernovae (CCSNe). Thus it is important to investigate the association between CCSNe and H II regions.
