Identifying the genes underlying adaptation is a major challenge in evolutionary biology. Here, we describe the molecular changes underlying adaptive coat color variation in a natural population of ...

Hydrogen-rich compounds hold promise as high-temperature superconductors under high pressures. Recent theoretical hydride structures on achieving h ...

Charge density wave (CDW) material 1T-TaS2 was proposed as a quantum spin liquid candidate, on which a cluster Mott insulator comes into being belo ...

Correction for “Exotic self-assembly of hard spheres in a morphometric solvent,” by Ivan Spirandelli, Rhoslyn Coles, Gero Friesecke, and Myfanwy E. Evans, which ...

Correction for Beal et al., Nutrient-dense foods and diverse diets are important for ensuring adequate nutrition across the life course ...

This work describes a flexible, solid-state, lithium-ion–conducting membrane based on a 3D ion-conducting network and polymer electrolyte for lithium batteries. The 3D ion-conducting network is based ...

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans ...

The Scattering of X-Rays and Bragg's LawNote: The article usage is presented with a three- to four-day delay and will update daily once available. Due to ths delay, usage data will not appear ...

The current Carbon Capture, utilization, and Storage (CCS) tax credit in the United States is unlikely to incentivize ...

Using data from rural monitoring sites across the contiguous United States, we evaluated fine particulate matter (PM2.5) trends for 1988–2016. We calculate trends in the policy-relevant 98th quanti ...

The limited fossil record of the giant panda Ailuropoda [Family Ursidae (1)] has, until recently, been primarily composed of teeth, mandibles, and a few skulls from the largest representative of the ...

Vivid, saturated structural colors are conspicuous and important features of many animals. A rich diversity of three-dimensional periodic photonic nanostructures is found in the chitinaceous ...
