G7.7-3.7: a young supernova remnant probably associated with the guest star in 386 CE (SN 386)
, 2018 Although the Galactic supernova rate is about 2 per century, only few supernova remnants are associated with historical records. There are a few ancient Chinese records of "guest stars" that are probably sightings of supernovae for which the associated ...

Oxychlorine Species on Mars: A Review
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Advanced Synthesis &Catalysis, Volume 367, Issue 21, November 13, 2025.In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

Dirac-Neutrino Magnetic Moment and the Dynamics of a Supernova Explosion
, 2009 The double conversion of the neutrino helicity $\nu_L \to \nu_R \to \nu_L$ has been analyzed for supernova conditions, where the first stage is due to the interaction of the neutrino magnetic moment with plasma electrons and protons in the supernova core,

Genomics‐led approach to drug testing in models of undifferentiated pleomorphic sarcoma
Molecular Oncology, Volume 19, Issue 11, Page 3223-3242, November 2025.GA text Genomic data from undifferentiated pleomorphic sarcoma patients and preclinical models were used to inform a targeted drug screen. Selected compounds were tested in 2D and 3D cultures of UPS cell lines. A combination of trametinib and infigratinib was synergistic in the majority of UPS cell lines tested, which was further confirmed in an ex ...

The Binary Fraction of B-type Runaway Stars from LAMOST DR8
The Astrophysical JournalRunaway stars are defined as stars that depart from their birth clusters at high peculiar velocities. There are two main mechanisms for the formation of runaway stars, i.e., the binary-supernova scenario (BSS) and the dynamical ejection scenario (DES ...

The Progenitor of the New COMPTEL/ROSAT Supernova Remnant in Vela
, 1999 We show that (1) the newly discovered supernova remnant (SNR), GRO J0852--4642/RX J0852.0--4622, was created by a core-collapse supernova of a massive star, and (2) the same supernova event which produced the $^{44}$Ti detected by COMPTEL from this ...

New Arabic Records From Cairo on Supernovae 1181 and 1006
Astronomische Nachrichten, Volume 346, Issue 9, November 2025.ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...
