In a phantom comparison of three CT systems, photon-counting CT generally detected and quantified lower iodine concentrations than dual-source and split-filter CT, especially in low-dose protocols.
A seven-star comparison found a sharp contrast between two ways of selecting slowly rotating, chemically peculiar A-type stars for magnetic-field searches.
Researchers used high-resolution 5-T MRI to compare cochlear nerve measurements in ears affected by acquired sensorineural hearing loss with measurements from control ears. The cochlear-aperture segment was smaller across several measures, while the study's cross-sectional design leaves cause and clinical prediction unresolved.
A high-entropy tungstenate and cerium-oxide catalyst on nickel foam showed strong alkaline OER results at high current densities, but the study did not test a complete electrolyzer or report replicate-based uncertainty.

A carbon-target photon experiment found a lower-tail excess in low-momentum η′→γγ events and inferred a possible 57.5 MeV/c² mass reduction at normal nuclear density, with an uncertainty of +5.7/−27.8 MeV/c².
The model recovered 70% of labeled likely young stars and added 14,426 candidates, but recall ranged from almost 100% in M dwarfs to about 0% in O-type stars.
A computational study reported perfect binary accuracy for an oscillator-only model using extracted formants, but lower performance for a raw-waveform pipeline and mixed results across 12 vowel classes.

A short VLA observing run on the single star AU Mic found strong variability even during selected quiet intervals, along with two clear flares. The authors interpret the pattern as evidence that many small, unresolved flares may help sustain the star’s radio emission, but the result is based on one star at one epoch.
The computational comparison found different modeled rare-earth abundance patterns across six nuclear level-density models and three simulated outflow scenarios, with the strongest contrast in the cold case.
Under a shared idealized climate setup, 18 of 22 selected Earth-like planets met the study's temperature-based habitability criteria. Stellar heating shaped the broad climate split more than rotation, while pressure mattered most for the hottest modeled worlds.
A numerical model matches the Crab Nebula's spectrum and apparent extension while predicting a roughly sixfold larger 1.1-PeV gamma-ray radius when hadronic emission is included.
A semianalytic simulation estimates how spectral deficits and periodic light curves could identify active supermassive binary black holes, with pulsar-timing forecasts offering a second test.

A computational study followed wide stellar triples from stellar birth to black-hole-binary merger, finding rare stable and unstable routes and distinct orbital and spin signatures.
A catalog from eROSITA's first survey lists 350 possible ultraluminous X-ray sources in HECATE galaxies, but uneven coverage, modeled contamination from active galactic nuclei and unresolved blends limit what it can show.

A narrative review of selected studies finds machine-learning methods are helping search survey data for hot subdwarfs and white dwarfs, while reported classifications and population estimates still require physical confirmation.
A laboratory study found that vapor-deposited cis-decalin and cis/trans-decalin glasses could be more stable than corresponding liquid-cooled glasses under specific deposition conditions, while pure trans-decalin did not yield a stable vapor-deposited glass.
A laboratory comparison in one lightly crosslinked PMMA glass found that probe-based mobility changed far more than a mechanical measure before yield, while the two measures tracked each other after yield.

A bulk organic crystal showed an intermediate-resistance state under applied current, and nuclear magnetic resonance measurements supported the coexistence of metallic and insulating regions. The sample’s average temperature stayed nearly fixed near its 79-kelvin transition while the power associated with the state rose as ambient temperature fell.

A technical review outlines four potential medical-imaging applications for microwave kinetic inductance detectors, while emphasizing that none has been clinically validated.

A study of interstellar comet 3I/ATLAS during its inbound, pre-perihelion passage found steady red optical colors, consistent brightening, a persistent sunward jet and an antisolar tail. Spectra clearly detected CN, while evidence for C2 and C3 remained at upper-limit level. Dust-composition and water-ice conclusions remain model-dependent.
