Highly efficient solar-based water sanitation

Solar-driven interfacial evaporation has potential for sustainable water sanitation, but controlling interfacial evaporators for solar tracking to ensure efficiency remains a challenge. Guo and colleagues create a black and super-wicking grooved surface that harnesses the sunlight and purifies water at an ultra-high level of efficiency.

    Reports on the widespread presence of plastic particles in the environment have raised concerns about whether these particles could be taken up by plants and end up on our plates. An experimental study now reveals a mechanism through which nanoplastics can make their way into plant roots.

    Accurate estimates of emissions distribution in a vehicle fleet can help air pollution control. With diesel emissions data from chassis dynamometer tests and on-road remote sensing, this study shows that previous results about a skewed distribution towards the highest 10% emitters may not be correct.

    The presence of microplastics in wastewaters used for irrigation highlights the urgency of analysing the possible uptake of microplastics by crop plants. This study shows that submicrometre and micrometre plastic particles from treated wastewater enter the steles of crop plants via a crack entry at sites of lateral root emergence.

    A new database of over 2,700 policies on nitrogen around the world highlights the predominance of policies incentivizing its use or managing trade, and the need for integration to avoid shifting pollution from one sink to another.

    International trade interacts with Sustainable Development Goal targets in profound ways. This study finds that while trade improves scores for environmental Sustainable Development Goals in developed countries, it decreases them in developing countries, and distant trade is a bigger contributor to scores than adjacent trade between countries.
