Novel field trial for ocean alkalinity enhancement using electrochemically derived aqueous alkalinity

Frontiers in Environmental Engineering
Ocean alkalinity enhancement is a proposed method of marine carbon dioxide removal that enhances the ocean’s uptake of atmospheric carbon dioxide (CO2) and converts it to dissolved bicarbonate for long-term ocean storage.

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Laying waste to the deep: parallel narratives of marine carbon dioxide removal and deep-seabed mining

npj Ocean Sustainability
The deep ocean is increasingly featured in climate solution discussions. An emerging narrative suggests that marine carbon dioxide removal (mCDR) is essential to meet global climate targets. The argument made is similar to claims that deep-seabed mining (

Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

Environmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Towards system-aware governance of marine carbon dioxide removal: a review of interdependent challenges

Environmental Research Letters
Marine carbon dioxide removal (mCDR) is increasingly discussed as a potential climate response, yet its governance remains underdeveloped. This study conducts a structured literature review, following the preferred reporting items for systematic reviews ...

Fertilising Climate Policy: The Dual Impact of CBAM on EU Agricultural Emissions and Regional Disparities

Journal of Agricultural Economics, EarlyView.
ABSTRACT The Carbon Border Adjustment Mechanism (CBAM), scheduled to become fully operational in 2026, is designed to complement the EU Emissions Trading System (ETS) by replacing free emission allowances and preventing carbon leakage to non‐EU regions. CBAM initially covers energy‐intensive sectors, including mineral nitrogen (N) fertiliser production.

Honokiol regulates Acute respiratory distress syndrome (ARDS)‐associated pulmonary fibrosis via the miR‐19a‐3p/POSTN axis

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Acute respiratory distress syndrome (ARDS) and subsequent pulmonary fibrosis are associated with high mortality and limited treatment options. Periostin (POSTN) is a profibrotic mediator predicted to be regulated by microRNA‐19a‐3p (miR‐19a‐3p), but the relevance of this axis in ARDS‐associated pulmonary fibrosis remains

Structural insights into θ‐type carbonic anhydrases 3 and 4: Tuning the directionality of CO2 hydration in a diatom

The FEBS Journal, EarlyView.
θ‐CA3 from a marine diatom has an N‐terminal transmembrane helix and two homologous catalytic domains. The enzyme functions as a dimer, with active sites formed near the dimer interface. A bicarbonate ion binds on the symmetry axis of the dimer and forms hydrogen bonds with both monomers, thereby activating θ‐CA3 and tuning CO2 hydration activity ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.
