Assessment of Circulating Tumor DNA for Early Detection of Hepatocellular Carcinoma in Alpha‐Fetoprotein–Negative Patients With Cirrhotic Nodules

JGH Open, Volume 10, Issue 1, January 2026.
ABSTRACT Aims Early detection is essential for improving hepatocellular carcinoma's (HCC) prognosis. However, the diagnostic performance of the current interventions remains unsatisfactory, particularly in patients with cirrhotic nodules. We aimed to develop a predictive model for the early detection of HCC using circulating tumor DNA (ctDNA) profiles ...

Holocene Glacial–Paraglacial–Periglacial Transitions of a Sub‐Arctic Glacial Cirque, Fremri‐Grasárdalur, Northern Iceland

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 78-106, January/March 2026.
ABSTRACT The aim of this work is to study a variety of glacial, periglacial and paraglacial features found in a small cirque, Fremri‐Grasárdalur, in Tröllaskagi (Northern Iceland). We implement a multidisciplinary approach combining high‐resolution geomorphological mapping, horizontal/vertical boulder displacement (from 1994 to 2019) and surface ...

METAL-Z: Measuring Dust Depletion in Low-metallicity Dwarf Galaxies

The Astrophysical Journal
The cycling of metals between interstellar gas and dust is a critical aspect of the baryon cycle of galaxies, yet our understanding of this process is limited. This study focuses on understanding dust depletion effects in the low-metallicity regime (

Bottom‐Up Synthesized B3N3‐Doped Amorphous Carbon Monolayer

Small Structures, Volume 7, Issue 1, January 2026.
B3N3‐doped amorphous carbon monolayers are synthesized through a UHV‐based strategy using surface‐assisted dehydrogenative intermolecular coupling of a functionalized borazine precursor, pyrene‐B3N3. After atomic‐scale characterization onthe growth substrate, the 2D material is transferred to Si/SiO2 and a TEM grid.

Deep‐Ultraviolet (DUV) Raman and Fluorescence of Perchlorates and Chlorates: Implications for the Detection of Oxychlorines by the SHERLOC Instrument in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...

An Analysis of the Exposure History of Apollo 17 Soils: Exploring Relationships Between Lunar Soil Maturity Indices

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Analysis of space weathering features in lunar regolith using transmission electron microscopy (TEM) allows researchers to characterize the surface exposure timescale of individual grains from the Moon. TEM analysis of regolith grains from Apollo 17 scoop samples, collected from five different locations in the Taurus‐Littrow Valley (TLV), each
