Highly deformable flapping membrane wings suppress the leading edge vortex in hover to perform better
Airborne insects generate a leading edge vortex when they flap their wings. This coherent vortex is a low-pressure region that enhances the lift of flapping wings compared to fixed wings. Insect wings...
Prey depletion, interspecific competition, and the energetics of hunting in endangered African wild dogs, <i>Lycaon pictus</i>
Large herbivores are in decline in much of the world, including sub-Saharan Africa, and true apex carnivores like the lion ( Panthera leo ) decline in parallel...
Correction for Knight and Zhang, Residential mobility and persistently depressed voting among disadvantaged adults in a large housing experiment
Correction for Baekgaard et al., Long-term employment and health effects of active labor market programs
Correction to Doruska et al., Modeling how and why aquatic vegetation removal can free rural households from poverty-disease traps
Correction to Supporting Information for Takaki and Thirumalai, Sequence complexity and monomer rigidity control the morphologies and aging dynamics of protein aggregates
Touching the classical scaling in penetrative convection
The Cassini missions have identified the tiger stripes on Enceladus as the source of both thermal emission and plume jets. The hot spots in the tiger stripes are highly localized, and the plumes sugge...
Identifying new classes of financial price jumps with wavelets
We introduce an unsupervised classification framework that leverages a multiscale wavelet representation of time-series and apply it to stock price jumps. In line with previous work, we recover the fa...
Temperature-dependent polar lignification of a seed coat suberin layer promoting dormancy in <i>Arabidopsis thaliana</i>
The seed is a landmark plant adaptation where the embryo is sheltered by a protective seed coat to facilitate dispersion. In Arabidopsis , the seed coat, derive...
Robust inattentive discrete choice
Rational inattention models characterize optimal decision-making in data-rich environments. In such environments, it can be costly to look carefully at all of the information. Some information is much...
Turbulence enhances wave attenuation of seagrass in combined wave–current flows
The wave attenuation properties of seagrasses are key to accurately predict how effective these plants are at protecting coasts from erosion and floods. While recent studies have significantly advance...
Thermal-solutal-induced bistability of evaporating multicomponent liquid thin films
Volatile multicomponent liquid films show rich dynamics, due to the complex interplay of gradients in temperature and in solute concentrations. Here, we study the evaporation dynamics of a tricomponen...
Anomalous suppression of large-scale density fluctuations in classical and quantum spin liquids
Classical spin liquids (CSLs) are intriguing states of matter that do not exhibit long-range magnetic order and are characterized by an extensive ground-state degeneracy. Adding quantum fluctuations,...
Aqueous power source integrated on a microfluidic chip
The growing demand for portable sensors for point-of-care (POC) and onsite health monitoring has led to significant interest in developing suitable power sources. In this study, we developed a microfl...
Out-of-distribution generalization via composition: A lens through induction heads in Transformers
Large language models (LLMs) such as GPT-4 sometimes appear to be creative, solving novel tasks often with a few demonstrations in the prompt. These tasks require the models to generalize on distribut...
The genomic and epigenomic landscapes of hemizygous genes across crops with contrasting reproductive systems
Hemizygous genes, which are present on only one of the two homologous chromosomes of diploid organisms, have been mainly studied in the context of sex chromosomes and sex-linked genes. However, these...
Contextual neural dynamics during time perception in the primate ventral premotor cortex
Understanding how time perception adapts to cognitive demands remains a significant challenge. In some contexts, the brain encodes time categorically (as “long” or “short”), while in others, it encode...
tRNA selectivity during ribosome-associated quality control regulates the critical sterility-inducing temperature in two-line hybrid rice
The two-line hybrid rice system, a cutting-edge hybrid rice breeding technology, has greatly boosted global food security. In thermo-sensitive genic male sterile (TGMS) lines, the critical sterility-i...
Top-performing girls are more impactful peer role models than boys, teachers say
We examine teachers’ perceptions toward top-performing students and their role model influence on others in an online survey-based experiment. We randomly expose teachers to profiles of top-performing...
The ER–PM interaction is essential for cytokinesis and recruits the actin cytoskeleton through the SCAR/WAVE complex
Plant cytokinesis requires coordination between the actin cytoskeleton, microtubules, and membranes to guide division plane formation and cell plate expansion; how these regulatory factors are coordin...
The structure of full-length AFPK supports the ACP linker in a role that regulates iterative polyketide and fatty acid assembly
The polyketide synthases (PKSs) in microbes and the cytoplasmic fatty acid synthases in humans (FASs) are related enzymes that have been well studied. As a result, there is a paradigm explaining in ge...
Microlevel structural poverty estimates for southern and eastern Africa
For many countries in the Global South traditional poverty estimates are available only infrequently and at coarse spatial resolutions, if at all. This limits decision-makers’ and analysts’ ability to...
Deep learning–driven bacterial cytological profiling to determine antimicrobial mechanisms in <i>Mycobacterium tuberculosis</i>
Tuberculosis (TB), caused by Mycobacterium tuberculosis , remains a significant global health threat, affecting an estimated 10.6 million people in 2022. The em...
G-quadruplexes catalyze protein folding by reshaping the energetic landscape
Many proteins have slow folding times in vitro that are physiologically untenable. To combat this challenge, ATP-dependent chaperonins are thought to possess the unique ability to catalyze protein fol...
Extrinsic induction of apoptosis and tumor suppression via the p53–Reprimo–Hippo–YAP/TAZ–p73 pathway
Tumor progression is suppressed by inherent cellular mechanisms such as apoptosis. The p53 tumor suppressor gene is the most commonly mutated gene in human canc...
