Glacier melt sustained water discharge from South America’s mountain basins during a recent severe drought, but summer runoff from glaciers could drop by 48% in future megadroughts, worsening water sc...

Aeolian dust deposition can deliver nutrients that fuel primary production in remote ocean regions. This Review considers how dust sources and nutrient composition, in addition to dust flux, have pote...

A quarter of a century after its publication, the biodiversity hotspot concept remains one of the most cited and influential frameworks in conservation science. But its real-world impact is poorly doc...

Rare earth elements (REEs) are critical metals for clean energy and high-tech applications, yet their supply faces environmental and geopolitical challenges. Phytomining, a green strategy using hyperaccumulator plants to extract metals from soil, offers potential for sustainable REE supply but remains underexplored. Here, we report the discovery of naturally formed nanoscale monazite in the fern Blechnum orientale, a REE hyperaccumulator plant. These REE minerals crystallize within extracellular tissues under ambient conditions, forming dendritic nanocrystals through biologically induced mineralization coupled with a non-equilibrium self-organization process. This represents the novel discovery of REE mineral crystals formed in living plants through a phytomineralization (i.e., plant-mediated mineralization) process. Our findings uncover a previously unrecognized, plant-mediated pathway for critical mineral formation in a supergene environment. This discovery not only sheds light on REE enrichment and sequestration during chemical and biological weathering but also opens new possibilities for the direct recovery of functional REE materials. This work substantiates the feasibility of phytomining and introduces an innovative, plant-based approach for sustainable REE resource development.

This global meta-analysis of freshwater stressor–response relationships reveals that the biodiversity loss of five riverine organism groups reflects elevated salinity, oxygen depletion and fine sedime...

Convective erosion and lateral transport of metasomatized continental keels may generate enriched mantle geochemical domains sampled by oceanic volcanism, according to a geodynamic modelling study.

Using population and ecological genomic approaches, the authors demonstrate the potential for interspecific introgression—the transfer of genetic material following hybridization—to reduce climate cha...

After it was found most offsets did not represent real carbon reductions, the money dried up. But successful schemes such as Kasigau in Kenya now face a stark future

Climate change will decrease Arctic Sea ice and increase light, but effects on polar ecosystems remain unclear. Here, the authors predict that warming waters and prey loss will threaten cold-water fis...

High near-surface nitrogen-fixation rates that promoted the recent growth of the Great Atlantic Sargassum Belt were tied to greater upwelling of phosphorus from the equatorial Atlantic, according to c...
