Infall Times for Milky Way Satellites From Their Present-Day Kinematics

open access: yes, 2011
We analyze subhalos in the Via Lactea II (VL2) cosmological simulation to look for correlations among their infall times and z = 0 dynamical properties.

Simultaneous inhibition of TRIM24 and TRIM28 sensitises prostate cancer cells to antiandrogen therapy, decreasing VEGF signalling and angiogenesis

open access: yesMolecular 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

Mid-infrared Extinction toward the Galactic Center

open access: yesThe Astrophysical Journal
We determine the mid-infrared (MIR, ∼5–22 μ m) extinction toward the Galactic center using MIRI/Medium-Resolution Spectrometer (MRS) integral field unit observations of the central 3″ × 3″ region (near 5 μ m) to 7″ × 7″ region (near 22 μ m).

Phenotypic and Genetic Characterization and Production Abilities of Lacticaseibacillus rhamnosus Strain 484—A New Probiotic Strain Isolated From Human Breast Milk

open access: yesFood Science &Nutrition, Volume 13, Issue 10, October 2025.
Human breast milk (HBM) is a recognized source of probiotic bacteria, with species such as Lacticaseibacillus rhamnosus demonstrating considerable potential for applications in both the medical and food industries. In this study, the probiotic potential of strain 484, isolated from HBM, was evaluated through comprehensive phenotypic and genetic ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

open access: yesJournal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

Sgr A* Spin and Mass Estimates through the Detection of Multiple Extremely Large Mass Ratio Inspirals

open access: yesThe Astrophysical Journal
We analyze the parameter estimation accuracy that can be achieved for the mass and spin of Sgr A*, the supermassive black hole in our Galactic center, by detecting multiple extremely large mass ratio inspirals (XMRIs).
