We investigated how subtle differences in epistemic language in headlines (e.g., “believe” vs. “know“) affect readers’ inferences about whether claims are perceived as matters of fact or mere opinion. (www.pnas.org)

The wooden artifacts from Schöningen’s Spear Horizon and their place in human evolution (www.pnas.org)
Wooden tools rarely survive in the Paleolithic record limiting our understanding of Pleistocene hunter-gather lifeways. With 187 wooden artifacts, Schöningen 13 II-4 provides the largest assemblage worldwide introduced here for the first time in full. Wooden tools include at least 10 spears and seven throwing sticks used in...

Brain-inspired computing with fluidic iontronic nanochannels (www.pnas.org)
Scientists have created an artificial synapse that works with water and salt, mimicking the medium used by our brains. This could lead to more efficient and energy-saving brain-inspired computers. The device, called an iontronic memristor, consists of a microchannel filled with water and salt, and can process complex information...

Agricultural intensification and childhood cancer in Brazil (www.pnas.org)
Pesticides are critical to agricultural intensification but can negatively impact human health. We show that as soy cultivation spread across Brazil, agricultural pesticide exposure was associated with increased childhood cancer mortality among the broader population indirectly exposed to these chemicals. We find that...

For the first time in the historical record, the world has experienced a year around 1.5 °C warmer than preindustrial temperatures. The extent to which the planet warms further has big consequences for local extremes of heat, drought, and precipitation.

Bodily maps of musical sensations across cultures (www.pnas.org)
Significance Music is inherently linked with the body. Here, we investigated how music’s emotional and structural aspects influence bodily sensations and whether these sensations are consistent across cultures. Bodily sensations evoked by music varied depending on its emotional qualities, and the music-induced bodily...
