Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, EarlyView.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Spatial conservation priorities for marine megafaunal predators: Multi‐taxon versus taxon‐specific approaches

Conservation Science and Practice
Marine megafaunal predators are globally threatened by anthropogenic stressors, but are key for ecosystem functioning. Their worsening conservation statuses indicate that current management is failing, requiring us to urgently reassess their conservation

Engineering a Virus‐Derived X Family DNA Polymerase FvPolX for de novo DNA Synthesis

Advanced Science, EarlyView.
In this study, a Faustovirus‐derived polymerase (FvPolX) is engineered based on structural and sequence analysis of PolX enzymes. The optimal mutants demonstrate substantially enhanced catalytic activity toward dNTPs and 3′‐ONH2‐dNTPs compared to the wild‐type enzyme.

Liver Kinase B1 in CD11c+ Cells Inhibits Fibrosis in Chronic Pancreatitis via the Oncostatin M Signaling

Advanced Science, EarlyView.
This study demonstrates significantly reduced Lkb1 expression in CD11c+ cells in chronic pancreatitis (CP) patients and animal models. Lkb1 deletion enhances CD11c+CD206+ macrophage infiltration and reprograms pancreatic stellate cells (PSCs) via OSM signaling.

SHARKlock holmes: Applications of DNA forensic in tackling illegal trade of sharks and rays in Southeast Asia Region [PDF]

BIO Web of Conferences
Globally, the market demand for fins, uncontrolled bycatch, and illegal fishing are all contributing to the sharp decline in shark and ray populations. Within two decades (2002–2021), ASEAN countries provided 19.4% of 15.06 million tons (2.9 million tons)

The vertical distribution and biological transport of marine microplastics across the epipelagic and mesopelagic water column. [PDF]

, 2019
Plastic waste has been documented in nearly all types of marine environments and has been found in species spanning all levels of marine food webs. Within these marine environments, deep pelagic waters encompass the largest ecosystems on Earth. We lack a
