Copper Stress Response of Antibiotic‐Resistant and Copper‐Tolerant Enterococcus faecium and the Antibacterial Efficacy of Functionalized Copper Surfaces

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.

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 ...

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

International Journal of Cancer, Volume 157, Issue 9, Page 1948-1962, 1 November 2025.
What's new? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.

Numerical Representation of Contemporary Atmospheric Δ14CO2: 1. Time‐Varying Global Fluxes and Atmospheric Mass Balance

Global Biogeochemical Cycles, Volume 39, Issue 11, November 2025.
Abstract Precise measurements of 14C:C in atmospheric CO2 (expressed as Δ14C) are increasingly used in contemporary carbon cycle studies as a tracer of various processes, including anthropogenic CO2 emissions from combustion of fossil fuels and cement production.

Metal-poor Star-forming Clumps in Cosmic Noon Galaxies: Evidence for Gas Inflow and Chemical Dilution Using JWST NIRISS

The Astrophysical Journal
The formation and evolution of galaxies are intricately linked to the baryon cycle, which fuels star formation while shaping chemical abundances within galaxies.

Near-infrared spectroscopy of a large sample of low-metallicity blue compact dwarf galaxies

, 2015
We present near-infrared (NIR) spectroscopic observations in the wavelength range 0.90-2.40mum of eighteen low-metallicity blue compact dwarf (BCD) galaxies and six HII regions in spiral and interacting galaxies.

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

Emission-line Diagnostics at z > 4: [O iii]λ4364/Hγ versus [Ne iii]λ3870/[O ii]λ3730

The Astrophysical Journal
We use JWST Near-Infrared Spectrograph observations from the Cosmic Evolution Early Release survey, GLASS-JWST ERS (GLASS), and JWST Advanced Deep Extragalactic Survey to measure rest-frame optical emission-line ratios of 89 galaxies at z  > 4.
