Head‐to‐head comparison of the diagnostic value of fecal and serum carcinoembryonic antigen for colorectal cancer detection

open access: yesInternational Journal of Cancer, Volume 159, Issue 2, Page 516-525, 15 July 2026.
What's new? The diagnostic value of fecal versus serum carcinoembryonic antigen (CEA) for colorectal cancer detection remains unclear. This study provides a head‐to‐head comparison of serum and fecal CEA using matched samples from two large colorectal cancer screening studies and two fecal sample processing methods.

A Well-Characterized Survey for Centaurs in Pan-STARRS1

open access: yesThe Astronomical Journal
To prepare for the upcoming Legacy Survey of Space and Time, we develop methods for quantifying the selection function of a wide-field survey as a function of all six orbital parameters and absolute magnitude. We perform a HelioLinC3D search for Centaurs

Seasonal Variation of Butterfly Diversity in Subtropical Urban Forests of Nepal

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Butterflies show seasonal fluctuations in diversity and population in response to bioclimatic factors. Studying butterflies in three urban forests in the subtropical region of Nepal, we found that the diversity and community composition differed significantly across seasons, with richness and diversity peaking during the monsoon and abundance peaking ...

Nitrogen-bearing Species on Trans-Neptunian Objects Revealed by JWST/DiSCo-TNOs

open access: yesThe Astrophysical Journal
C≡N-bearing species are valuable tracers of nitrogen chemistry in the solar system. Ranging from volatile compounds like HCN and CH _3 CN in cometary comae to refractory CN-bearing organics in some micrometeorites and interplanetary dust particles, these

On the Border: Searching for Cometary Activity near the Centaur–JFC Transition Line

open access: yesThe Planetary Science Journal
Current wide-field surveys discover ∼15 Jupiter-family comets (JFCs) each year, typically identified via visual detection of a dust coma or tail. The same surveys also discover many asteroids that have distant JFC-like orbits, but with no reported ...

Evaluation of a high‐sensitivity cardiac troponin I assay compared to a first‐generation cardiac troponin I assay in Doberman Pinschers with and without dilated cardiomyopathy

open access: yesJournal of Veterinary Internal Medicine, 2019
Background Echocardiography and 24‐hour ECG are the gold standard tests to diagnose dilated cardiomyopathy (DCM) in Doberman Pinschers (DP), but myocardial damage might be detected earlier using a high‐sensitivity cardiac troponin I (hs‐cTnI) assay ...

Ejected Surface Regolith as a Potential Source Material for Centaur Rings

open access: yesThe Planetary Science Journal
Ring systems have been observed around Centaur Chariklo (10199) and other small bodies but their origin and dynamical histories are still debated. These small body ring systems challenge conventional models for the origin of planetary rings, especially ...

Multiyear Ground-based Survey Photometry of Active Comet 103P/Hartley 2 and Centaur (2060) Chiron: A Tale of Two Comets in the Pre-LSST Era

open access: yesThe Planetary Science Journal
Comets and Centaurs trace the evolution of trans-Neptunian objects (TNOs) into the inner solar system. Their activity reflects the interplay between volatile sublimation, dust dynamics, and, in some cases, ring scattering.

People can understand descriptions of motion without activating visual motion brain regions

open access: yesFrontiers in Psychology, 2013
What is the relationship between our perceptual and linguistic representations of the same event? We approached this question by asking to whether visual perception of motion and understanding linguistic depictions of motion rely on the same neural ...

Analyzing the Onset of Cometary Activity by the Jupiter-family Comet 2023 RN3

open access: yesThe Astronomical Journal
We utilize serendipitous observations from the Asteroid Terrestrial-impact Last Alert System (ATLAS) and the Zwicky Transient Facility in addition to targeted follow-up observations from the Las Cumbres Observatory (LCO) and Liverpool Telescope to ...
