Characterization of the Nature of Organic Matter in Carbonate Rocks: Implications for Geological and Environmental Studies

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Organic matter in carbonate rocks plays a crucial role in processes such as fluid flow regulation, carbon sequestration, contaminant transport, and hydrocarbon recovery. This study employed multimodal spectroscopic techniques, including fluorescence imaging and Fourier transform infrared (FTIR) spectroscopy, to characterize the spatial ...

The Cosmic Ultraviolet Baryon Survey (CUBS). VIII. Group Environment of the Most Luminous Quasars at z ≈ 1

The Astrophysical Journal
We investigate the group-scale environment of 15 luminous quasars (luminosity L _3000 > 10 ^46 erg s ^−1 ) from the Cosmic Ultraviolet Baryon Survey (CUBS) at redshift z ≈ 1.

Acute metabolic responses to high‐intensity interval training in men with overweight or obesity: Does the exercise modality matter?

Experimental Physiology, Volume 111, Issue 3, Page 904-915, 1 March 2026.
Abstract This study investigated the acute effects of two isoenergetic high‐intensity interval exercise (HIIE) sessions, running (HIIE‐RUN) and cycling (HIIE‐BIKE), on post‐exercise oxygen consumption (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$), carbon dioxide production (V̇CO2${\dot V_{{\mathrm{C}}{{\mathrm{O}}_2}}}$), substrate oxidation and 24‐h energy ...

Comprehensive Connection among the Quasars with Different Types of Outflow Absorption Lines

The Astrophysical Journal
It is commonly accepted that outflows from the central regions of quasars play a substantial role in regulating the global properties of the host galaxy. These outflows are typically detected through blueshifted absorption lines.

Evaluation of QUASAR Insight Phantom for daily imaging QA of MRgRT linacs

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Purpose Magnetic resonance imaging (MRI) and its importance in modern radiation therapy requires a standardized daily quality assurance (QA) procedure that is both comprehensive and efficient. Current imaging QA guidelines require a more inclusive analysis of imaging characteristics, as well as a simplification of setup procedures.

Narrow [O iii] Emission Lines as a Potential Proxy for the Evolutionary Stage of Quasars

The Astrophysical Journal
Radio spectral shape of quasars can provide insight into the ages of quasars. We have compiled data for 1804 quasars with z ≲ 1 from the Sloan Digital Sky Survey (SDSS).

Formation of Condition‐Dependent Alpha‐Synuclein Fibril Strain in Artificial Cerebrospinal Fluid

Advanced Science, Volume 13, Issue 7, 3 February 2026.
α‐synuclein aggregation in artificial cerebrospinal fluid (aCSF) leads to a distinct conformation with an electron density pocket motif found in aggregates from PD and MSA patients. Such fibrils has low stability outside the reaction conditions, hinting about the influence of cerebrospinal fluid components not only on the formation, but also on the ...

Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication

Advanced Science, Volume 13, Issue 8, 9 February 2026.
EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.
