Zero‐Shot Self‐Supervised Learning of Single Breath‐Hold Magnetic Resonance Cholangiopancreatography (MRCP) Reconstruction

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1666-1681, October 2026.
ABSTRACT Purpose To investigate the feasibility of zero‐shot self‐supervised learning reconstruction for reducing breath‐hold times in magnetic resonance cholangiopancreatography (MRCP). Methods Breath‐hold MRCP was acquired from 11 healthy volunteers on 3T scanners using an incoherent k‐space sampling pattern, leading to a 14‐s acquisition time and an

Bioactive Gold Plasmonic Interfaces Meet Artificial Intelligence: Advancing Saliva‐Based Surface‐Enhanced Raman Spectroscopy Diagnostics

Small, Volume 22, Issue 59, 22 October 2026.
ABSTRACT Bioactive gold plasmonic nanostructures are enabling non‐invasive saliva diagnostics by amplifying weak Raman signals and converting complex biofluid chemistry into information‐rich spectral fingerprints. This Review examines saliva‐based Raman and surface‐enhanced Raman spectroscopy (SERS) integrated with artificial intelligence (AI) from a ...

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Distinguishing Potential Organic Biosignatures on Ocean Worlds from Abiotic Geochemical Products using Thermodynamic Calculations [PDF]

The search for life in our solar system often involves efforts to detect organic molecules, which have been found on many extraterrestrial bodies, including planets, moons, meteorites, comets, and asteroids.

Biosignatures and tracers of life

, 2023
Biosignatures are widely sought after within the solar system and exoplanet communities. But what are we talking about, when we talk about biosignatures?

Unveiling microbial preservation under hyperacidic and oxidizing conditions in the Oligocene Rio Tinto deposit

Scientific Reports, 2021
The preservation of biosignatures on Mars is largely associated with extensive deposits of clays formed under mild early Noachian conditions (> 3.9 Ga). They were followed by widespread precipitation of acidic sulfates considered adverse for biomolecule ...

Fossilised Pioneer Microbialite Communities on Basaltic Substrates at Lake Ashenge (Tigray, Ethiopia): A Model for Ecosystems in Noachian–Hesperian Martian Lakes?

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Microbial communities are strongly controlled by local nutrient availability, frequently resulting from mineral weathering and erosion. On Earth, basaltic rocks in habitable alkaline lacustrine environments are often initially colonised by ‘pioneer’ communities that induce the precipitation of fine‐scale microbial carbonate ‘coatings’; on Mars,
