We present the first ever global account of the production, use, and end-of-life fate of all plastics ever made by humankind.

Global water scarcity assessment at a high spatial and temporal resolution, accounting for environmental flow requirements.

Researchers developed a perovskite solar cell with high power-conversion efficiency (>20%) and intense electroluminescence yield (0.5%).

Freeform reversible embedding of suspended hydrogels enables three-dimensional printing of soft extracellular matrix biopolymers in biomimetic structures.

Gingipains from Porphyromonas gingivalis drive Alzheimer’s pathology and can be blocked with small-molecule inhibitors.

We describe the challenges and opportunities of analyzing links between exposure to air pollution and vulnerability to COVID-19.

Aqueous batteries are a reliable alternative for next-generation safe, low-cost, and scalable energy storage.

We provide consensus on the benefits of nature experience for mental health, and a model for integrating them into urban design.

The world atlas of zenith artificial night sky brightness is modelled with VIIRS DNB data and calibrated with more than 35,000 observations.

A polymer is described that is conductive and stretchable, which can lead to electronics that can conform to the human body.
