Main text Please take note of the following when preparing your manuscript for PNAS: Do not include statements of novelty or priority. Avoid laboratory jargon. Use correct chemical names. Specify ...

The Earth’s rotation has been decelerating throughout its history due to tidal dissipation, but the variation of the rate of this deceleration through time has not been established. We present a ...

Hamiltonian Systems and Transformation in Hilbert SpaceInteger partitions arise naturally in additive number theory, algebraic geometry, combinatorics, mathematical physics, and representation theory.

The discovery of Lophiostroma leizunia Jeon sp. nov., a 480-My-old phosphatic stromatoporoid sponge from South China, revolutionizes our understanding of early reef ecosystems and biomineralization.

Resolving the complex evolutionary history of polyploid species like octoploid strawberry is challenging due to the number of potential progenitors and the potential for hybridization events within ...

Many cities seek to alleviate extreme heat via planting trees. However, the cooling achieved by such programs is debated because previous analyses address scales much smaller than the whole-city scale ...

The expansion of marine protected areas (MPAs) is a crucial part of global conservation efforts (1). The “30x30” initiative, for example, aims to protect at least 30% of the world’s oceans by 2030 ...

Filtration is essential for healthy modern living and for many industrial processes. In filter design, permeability and selectivity are both desirable and are selected following trade-off analyses.

A cure for chronic hepatitis B requires eliminating or permanently silencing covalently closed circular DNA (cccDNA). A pivotal target of this approach is the hepatitis B virus (HBV) X protein (HBx), ...

Lockdowns were implemented to reduce the transmission of the COVID-19 virus. However, it is unclear how severely curtailed physical interaction shapes individual behaviors that are considered vital ...

Dysregulation of AMPA receptors (AMPARs) contributes to a number of neurological and psychiatric disorders, including AD. However, studying longitudinal AMPAR changes in AD animals has been a big ...
