What’s new from New Horizons: Clean water ice on Pluto’s far-out moon, Hydra
Continuous directional water transport on the peristome surface of Nepenthes alata
Numerous natural systems contain surfaces or threads that enable directional water transport. This behaviour is usually ascribed to hierarchical structural features at the microscale and nanoscale, with gradients in surface energy and gradients in Laplace pressure thought to be the main driving forces. Here we study the prey-trapping pitcher organs of the carnivorous plant Nepenthes alata. We find that continuous, directional water transport occurs...
A pentanuclear iron catalyst designed for water oxidation
Although the oxidation of water is efficiently catalysed by the oxygen-evolving complex in photosystem II (refs 1 and 2), it remains one of the main bottlenecks when aiming for synthetic chemical fuel production powered by sunlight or electricity. Consequently, the development of active and stable water oxidation catalysts is crucial, with heterogeneous systems considered more suitable for practical use and their homogeneous counterparts more...

Map reveals that there’s more water ice on Pluto
A color-coded map from NASA’s New Horizons mission shows where Pluto’s frozen water is concentrated, just in case we need to fill up our tanks on the way to Alpha Centauri or Planet Nine. Water ice turns out to be more widespread on...
Want to help Flint residents in the wake of the water crisis? Here’s their Amazon Wish List
Living in the Northwest, it’s easy to take clean, potable water for granted. And although sharing our water supply isn’t an option, there is an easy, tangible way to help Flint, Mich., during its serious water crisis. Salem Lutheran Church...
Uranium-mediated electrocatalytic dihydrogen production from water
Depleted uranium is a mildly radioactive waste product that is stockpiled worldwide. The chemical reactivity of uranium complexes is well documented, including the stoichiometric activation of small molecules of biological and industrial interest such as H2O, CO2, CO, or N2 (refs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11), but catalytic transformations with actinides remain underexplored in comparison to transition-metal catalysis....

Exposed water ice on the nucleus of comet 67P/Churyumov–Gerasimenko
Although water vapour is the main species observed in the coma of comet 67P/Churyumov–Gerasimenko and water is the major constituent of cometary nuclei, limited evidence for exposed water-ice regions on the surface of the nucleus has been found so far. The absence of large regions of exposed water ice seems a common finding on the surfaces of many of the comets observed so far....
