We investigate the emissions of two potent greenhouse gases, perfluorocarbons tetrafluoromethane (CF 4, PFC-14) and hexafluoroethane (C 2 F 6, PFC-116), in China. Based on atmospheric observations ...

We examine i) whether the public views AI as labor-replacing rather than labor-creating, and ii) how these perceptions affect two core democratic outcomes: democratic legitimacy (e.g., satisfaction ...

Coral reef fish may be more important than we thought ...

The ocean and land absorb anthropogenic C O 2 from industrial fossil-fuel emissions and land-use changes, helping to buffer climate change. Here, we compare decadal variability of ocean C O 2 uptake ...

Open in Viewer RoBMA PSMA model-averaged posterior mean effect size estimates with 95% credible intervals and Bayes factors for the absence of the effect for the combined sample or split by either the ...

Plastic waste causes harm to marine life and has become a major global environmental concern. The recent COVID-19 pandemic has led to an increased demand for single-use plastic, intensifying pressure ...

Rapid Arctic warming has intensified northern wildfires and is thawing carbon-rich permafrost. Carbon emissions from permafrost thaw and Arctic wildfires, which are not fully accounted for in global ...

The half-inch-long corn rootworm larva packs a surprising punch. It feasts on the root system of corn before pupating into a black and yellow beetle that does further damage to the plant’s leaves.

Wheat is the most important food crop worldwide, grown across millions of hectares. Wheat yields in the field are usually low and vary with weather, soil, and crop management practices. We show that ...

In PNAS, the liquid crystal group of the Soft Materials Research Center at the University of Colorado Boulder, led by N. A. Clark, reports on the discovery of a ferroelectric nematic fluid N F, an ...

Tropical cyclones (TCs), and particularly major TCs, pose substantial risk to many regions around the globe. Identifying changes in this risk and determining causal factors for the changes is a ...

Functional diversity in a lipidome In their study, Schuhmacher et al. (5) use the tools of chemical biology to synthesize individual molecular species of DAG including stearyl arachidonyl DAG (SAG) as ...
