5-T MRI finds a smaller cochlear nerve segment in hearing-loss ears
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.

Nickel-foam catalyst holds high current for more than 100 hours
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.

Lead-free capacitors convert heat into electricity in lab tests
A lead-free barium strontium titanate capacitor design generated electrical energy across a wide temperature range, with its best incremental output concentrated between 40 °C and 50 °C.

Preprint reports a possible η′ mass shift inside carbon nuclei
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.

Oscillator network reaches 100% on a two-vowel test
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.

Climate models classify 18 tidally locked exoplanets as potentially habitable
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.

Crab Nebula model predicts a much wider PeV gamma-ray glow
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.

Models estimate hundreds of supermassive black-hole pair candidates
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.

Preprint catalogs 350 possible ultraluminous X-ray sources
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.

Machine Learning Helps Find Rare Hot Subdwarfs and White Dwarfs
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.

Vapor-deposited decalin glasses show unusual stability
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.

Two mobility measures in a polymer glass diverged before yield
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.

Current reveals mixed metal-insulator state in bulk organic crystal
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.

Preprint: Interstellar comet 3I/ATLAS brightened while its colors stayed nearly unchanged
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.
