Closed-loop microalgal CO₂ capture integrates circular bioeconomy with decarbonization. Hybrid photobioreactors and nutrient recycling boost biomass and CO₂ utilization. Industrial pilot projects show pathways to scale up microalgae-based CO₂ capture. Industrial symbiosis and regulatory advances drive market adoption of CO₂ capture.

Epiphytes – plants that grow on other plants – can move and absorb water across their leaf surfaces using specialized hairs. In bromeliads, this ability is found in species from dry, seasonal habitats and is linked to having less efficient internal water transport. This discovery highlights how plants evolve creative solutions to survive in challenging environments.

As plants experience drought, transpiration rates decrease and can reduce carbon assimilation, biomass production and yield. We evaluated how melon plants, exposed to drought, changed their water status at predawn and midday to identify thresholds when drought compromises plant performance. We identified the transition from water-consumptive (higher transpiration) to water-conservative (limited transpiration) behaviour, and propose that this approach can be used to better manage irrigation and support effective use of water without a yield decrease.

Sustainable agricultural practices play a crucial role in enhancing crop productivity and quality while minimizing environmental impact. The effects of various fertilizers: synthetic, organic (cow manure, vermicompost), and their combinations, on the growth, nutrient content, and essential oil composition of Zataria multiflora Boiss. over 2 years in field conditions were examined. Results show that organic fertilizers improve soil health, promote plant growth, and increase essential oil yield while enriching the aromatic profile, suggesting that eco-friendly fertilization practices can enhance productivity and sustainability.
