Assessing the ergodicity of graphene liquid cell electron microscope measurements, we report that loop states of circular DNA interconvert reversibly and that loop numbers follow the Boltzmann ...

Number 1A, 1948 by Jackson Pollock is an iconic example of the artist’s action painting technique. The red and yellow pigments used in the painting have been previously identified, but the painting ...

Flowering plants have evolved various types of physical defense mechanisms, such as thorns, prickles, and spines, to protect against herbivory. The common feature of these sharp structures is the ...

As climate change accelerates, effectively monitoring and managing the growing impacts on biodiversity is an urgent priority. Here, we identify the exposure of species to unprecedented heat to ...

Predictability and the pleasure of musicEmotions coordinate our behavior and physiological states during survival-salient events and pleasurable interactions. Even though we are often consciously ...

Correction for Yang et al., How surface charges affect interdroplet freezing ...

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 insoluble ...

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 ...

Animal models and human studies suggest that forever chemicals, delivered through water, food, and air, alter the immune system, potentially diminishing our ability to fight disease or respond to a ...

Mandatory and voluntary mask policies may have yet unknown social and behavioral consequences related to the effectiveness of the measure, stigmatization, and perceived fairness. Serial ...

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 ...
