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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

There has been recent interest in flexible safe energy devices, based on supercapacitors and batteries, to meet the various requirements of modern gadgets (1 – 3). Electrochemical energy can be stored ...
