Membrane-based ion selective separation technology offers a promising solution for lithium extraction from brines. A counterion effect created by the design of positively charged ion transport channels of membranes exhibits a high-speed transport pathway for lithium-ion and enhanced lithium/magnesium ion selectivity.

The global drought community and policy representatives gathered at the United Nations Convention to Combat Desertification’s 16th Conference of the Parties (UNCCD COP16) in Riyadh in December 2024 to discuss the urgent need for improvements in assessing and quantifying drought risks, in developing and implementing transformative solutions, and in boosting policy actions and investments. Only through unprecedented global cooperation can we facilitate pathways towards drought-resilient futures.

Salt marshes are hotspots of nutrient processing and carbon sequestration. So far, studies addressing spatiotemporal variability in and drivers of salt marsh biogeochemical function, carbon storage and resilience have focused on ocean-driven surface hydrologic influences, neglecting effects of terrestrial hydrology through subsurface connections. Here we evaluate drivers of salt marsh redox potential, a proxy for biogeochemical state, through wavelet analyses and information theory using data from seven marshes. The results point to terrestrial groundwater level as a dominant control on redox variability across all sites. Because redox is a key driver of biogeochemical processes, and specifically oxidation of organic matter that sequesters carbon and maintains marsh elevation, these terrestrial influences are critical to understanding marsh function and evolution. The newly identified links between onshore groundwater levels and marsh redox conditions shift the traditional paradigm and suggest that terrestrial hydrology is a primary control on salt marsh carbon sequestration potential and resilience. This study investigates drivers of redox potential in several salt marsh sites on the basis of time series datasets. Wavelet and mutual information analyses show that the terrestrial groundwater level, rather than the marsh groundwater level, is the dominant control on redox potential.

The water and sewerage companies (WaSCs) in England are majority-owned by a range of global investors. The industry is under intense scrutiny for widespread failure in its environmental performance, discharging 12.7 million monitored hours of untreated wastewater and sewage into English waterways between 2019 and the end of 2023. At the time of writing, multiple investigations by environmental and financial regulators are in progress, and regulatory oversight is under review by the recently formed Office for Environmental Protection. While limited monitoring hid the full extent of underperformance, we argue that the WaSCs have prolonged this environmental disaster through strategies that mirror those of other large polluting industries in the past. We test this hypothesis for the nine major WaSCs in England against a published framework of 28 ‘greenwashing/deception’ tactics of large industries. We identified 22 of these tactics that could be seen as disinformation, greenwashing and manufacturing doubt. The financial exploitation of water resources in England, alongside long-term degradation of infrastructure and ineffective regulation, raises globally important issues around water security, ethics and environmental stewardship. Much greater scrutiny of both industry performance and industry communication is required. In the past 5 years, a huge amount of untreated wastewater has been released into English waterways. An analysis of the communication used by the water utilities shows that they have employed strategies used by large polluting industries in the past, prolonging the consequences of this environmental disaster.
