In Vivo Microplastic Detection With Photoacoustic Imaging

open access: yesAdvanced Science, EarlyView.
ABSTRACT Microplastics are posing an escalating threat to both ecological systems and human health. Yet, current methods for investigating their bioaccumulation are highly invasive, requiring destructive analysis of ex vivo tissues via mass spectrometry, dye labelling, or Raman microspectroscopy.

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Precision Lignocellulosic Biorefinery: Process Regulation From Corn Stover to Products

open access: yesAdvanced Science, EarlyView.
This study presents a precision biorefinery framework that transforms corn stover into high‐value bioproducts through whole‐process regulation. Mechanical fractionation separates feedstock into parenchyma‐rich short fibers and vascular‐bundle‐dominant long fibers.

Geomorphology and Mineralogy of Belén Crater in Iani Chaos (Mars) Point to Hydrothermal Activity

open access: yesThe Planetary Science Journal
The study of Martian chaotic terrains helps constrain the ancient geologic history of the Martian water cycle, as these regions preserve geomorphic and mineralogical evidence of catastrophic groundwater release, subsurface ice melting, and associated ...

Focused Lunar Imaging Experiment Using the Back Projection Algorithm Based on Sanya Incoherent Scatter Radar

open access: yesRemote Sensing, 2022
Previous ground-based, radar lunar imaging experiments have usually employed the Range-Doppler (RD) algorithm. This algorithm performs in the frequency domain and has high computational efficiency. However, in the case of a long coherent integration time,

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

open access: yesAdvanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.

Potential Landing Sites: A Comprehensive Reconnaissance Assessment of the Europa Clipper Trajectory

open access: yesThe Planetary Science Journal
NASA’s Europa Clipper mission will explore Jupiter’s icy moon via multiple flybys in the early 2030s. The ocean world Europa is one of the most promising locations to search for life elsewhere in the solar system, and thus Europa Clipper’s main goal is ...

Ionospheric Nighttime Enhancements at Low Latitudes Challenge Performance of the Global Ionospheric Maps

open access: yesRemote Sensing, 2022
In this study, two ionospheric nighttime enhancement (INE) events at low latitudes are selected to investigate their spatial features through the observations from Global Navigation Satellite System (GNSS) receivers and ionosondes. For the first time, we
