Day-to-day fluctuations in motivation drive effort-based decision-making
Internal states like motivation fluctuate substantially over time. However, studies of the neurocomputational mechanims of motivated behavior have failed to capture this. Here, we examined how natural...
Predicting nature-based coastal protection by mangroves under extreme waves
Forested wetlands such as mangroves are considered highly valuable for nature-based mitigation of coastal flooding. However, their wave attenuation capacity during extreme storms, when risks are highe...
US grass-fed beef is as carbon intensive as industrial beef and ≈10-fold more intensive than common protein-dense alternatives
The high resource intensity of industrial beef in high-income economies has prompted growing interest in alternative, potentially lower environmental impact beef production pathways. Of those, grass f...
Correction to Supporting Information for Utzschneider et al., Force balance of opposing diffusive motors generates polarity-sorted microtubule patterns
Correction for Bednarek et al., How and why funders support engaged research
Reply to Grossman et al.: The case for a time-varying oxygen isotopic composition of seawater and cooler Ordovician oceans
The TEA domain transcription factors TEAD1 and TEAD3 and WNT signaling determine HLA-G expression in human extravillous trophoblasts
Maternal–fetal immune tolerance guarantees a successful pregnancy throughout gestation. HLA-G, a nonclassical human leukocyte antigen (HLA) molecule exclusively expressed in extravillous trophoblasts...
Dynamics of an algae–bacteria microcosm: Photosynthesis, chemotaxis, and expulsion in inhomogeneous active matter
In nature, there are significant relationships known between microorganisms from two kingdoms of life, as in the supply of vitamin B 12 by bacteria to algae. Su...
Constructed languages are processed by the same brain mechanisms as natural languages
What constitutes a language? Natural languages share features with other domains: from math, to music, to gesture. However, the brain mechanisms that process linguistic input are highly specialized, s...
Reply to Ahmed and Lu: Cluster signals depend on how samples are made and measured
Spatially resolved charge-transfer kinetics at the quantum dot–microbe interface using fluorescence lifetime imaging microscopy
Integrating the optoelectronic properties of quantum dots (QDs) with biological enzymatic systems to form microbe-semiconductor biohybrids offers promising prospects for both solar-to-chemical convers...
Correction for Colen et al., Machine learning active-nematic hydrodynamics
Flycodes enable simultaneous preclinical analysis for dozens of antibodies in single cassette–dosed mice
Protein therapeutics such as antibodies require in-depth in vivo characterization during development and consequently account for a large proportion of laboratory animal consumption in the pharmaceuti...
Building better biochronology: New fossils and <sup>40</sup> Ar/ <sup>39</sup> Ar radioisotopic dates from Central Anatolia
Türkiye’s geographic position between Europe, Asia, and Africa gives it pivotal importance for understanding the local, interregional, and intercontinental dynamics of Neogene vertebrate evolution. Al...
Absence of water clusters in visible light interactions with the air–water interface
Audible enclaves crafted by nonlinear self-bending ultrasonic beams
Delivering audible content to a targeted listener without disturbing others is paramount in audio engineering. However, achieving this goal has long been challenging due to the diffraction of low-freq...
Embryonic reprogramming of the tumor vasculature reveals targets for cancer therapy
A sustained blood supply is critical for tumor growth, as it delivers the nutrients and oxygen required for development. Targeting of blood vessel formation via immunotherapies is an area of great imp...
