The Middle Pleistocene (MP; ca. 774 to 129 ka) marks a critical period of human evolution, characterized by increasing behavioral complexity and the first unambiguous evidence of plant-based ...

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 ...

Scientific understanding of microbial biogeography is particularly weak for soil bacteria, even though the diversity and composition of soil bacterial communities is thought to have a direct influence ...

The discovery of high-temperature superconductivity in iron pnictides raised the possibility of an unconventional superconducting mechanism in multiband materials. The observation of Fermi-surface ...

Abstract Extracellular redox-active compounds, flavins and other quinones, have been hypothesized to play a major role in the delivery of electrons from cellular metabolic systems to extracellular ...

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 ...

Lower socioeconomic status (SES) is a determinant of many of the health problems that emerge at older ages. The extent to which lower SES is associated with faster decline in age-related functions and ...

We show that for thousands of years, humans have concentrated in a surprisingly narrow subset of Earth’s available climates, characterized by mean annual temperatures around ∼13 °C. This distribution ...

Modern genetic analysis has revealed genetic differentiation across the south of Britain and Ireland. This structure demonstrates the impact of hegemonies and migrations from the histories of Britain ...

A phase transition from a liquid to an ordered solid state in two dimensions is different from that in three dimensions. In two dimensions, the appearance of quasi–long-range orientational ...
