Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Spiral arm pitch angle and galactic shear rate in N-body simulations of disc galaxies [PDF]
, 2012 Spiral galaxies are observed to exhibit a range of morphologies, in particular in the shape of spiral arms. A key diagnostic parameter is the pitch angle, which describes how tightly wound the spiral arms are.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The SWELLS survey - V. A Salpeter stellar initial mass function in the bulges of massive spiral galaxies [PDF]
, 2012 Recent work has suggested that the stellar initial mass function (IMF) is not universal, but rather is correlated with galaxy stellar mass, stellar velocity dispersion or morphological type.

Synergies in Self‐Assembly—From Supramolecular Polymers to Defined Hierarchical Superstructures
Journal of Polymer Science, Volume 63, Issue 21, Page 4450-4465, 1 November 2025.Shaping supramolecular polymers built from molecular building blocks into superstructures with defined dimensions. Synergies within supramolecular architectures such as chirality or an additional second orthogonal driving force that does not interfere with the central supramolecular motif facilitate the confinement of the growth of these ...

Proton‐linked effects on the axial coordination in ferric and ferrous horse heart cytochrome c
Protein Science, Volume 34, Issue 11, November 2025.Abstract The effect of pH (between pH 7.0 and 0.0) on the spectroscopic properties of ferric and ferrous derivatives of horse heart cytochrome c (hhcytc‐Fe(III) and hhcytc‐Fe(II), respectively) in 1.0M phosphate buffer is reported. This study further deepens the investigation of spectroscopic properties of a heme‐protein to very low pH (i.e., pH ≈ 0 ...

Evidence for spin alignment of spiral and elliptical/S0 galaxies in filaments [PDF]
, 2012 Galaxies are not distributed randomly in the cosmic web but are instead arranged infilaments and sheets surrounding cosmic voids. Observationally there is still no con-vincing evidence of a link between the properties of galaxies and their host structures.

Molecular Oncology, Volume 19, Issue 10, Page 2797-2821, October 2025.TRIM24 and TRIM28 are androgen receptor (AR) coregulators which exhibit increased expression with cancer progression. Both TRIM24 and TRIM28 combine to influence the response of castrate‐resistant prostate cancer (CRPC) cells to AR inhibitors by mediating AR signalling, regulation of MYC and upregulating VEGF to promote angiogenesis. Castrate‐resistant
