To understand the breadth of enterococcal diversity, we examined little-sampled (non-clinical, non-human) environments, including those minimally impacted by human habitation or pollution. To maximize ...

Lignin is an energy-dense, heterogeneous polymer comprised of phenylpropanoid monomers used by plants for structure, water transport, and defense, and it is the second most abundant biopolymer on ...

PNAS is dedicated to publishing cutting-edge research in sustainability science. We encourage authors to submit research on the interactions between natural and social systems, and on how those ...

Two common findings from past research on sleep duration are that people who sleep too little suffer from various health consequences and that people from some cultures often have sleep durations that ...

The Miocene is distinguished by extreme climatic optima alternating with major long-term climatic cooling, which together mark the founding of the modern late Cenozoic cold mode and the evolution of ...

Forecasts of species vulnerability and extinction risk under future climate change commonly ignore local adaptations despite their importance for determining the potential of populations to respond to ...

pWA2 Soluble periplasmic hexa-His-tagged AcrA under control of Tet promoter, in pBR322, Amp R This work pMH2 Soluble periplasmic hexa-His-tagged AcrA (N123L) under control of Tet promoter, in pBR322, ...

A moiré pattern is formed when two copies of a periodic pattern are overlaid with a relative twist. We address the electronic structure of a twisted two-layer graphene system, showing that in its ...

We discovered a dual role of vimentin underlying Zika virus (ZIKV) replication. The vimentin network reorganizes to surround the replication complex. Depletion of vimentin resulted in drastic ...

Understanding how ecosystems respond to ubiquitous microplastic (MP) pollution is crucial for ensuring global food security. Here, we conduct a multiecosystem meta-analysis of 3,286 data points and ...

A mutation in salt-induced kinase 3 (hSIK3-N783Y) is identified in a human subject exhibiting the natural short sleep duration trait. A mouse model carrying this homologous mutation demonstrates ...
