Posttranslational modifications, including acetylation and deacetylation of histones and other proteins, modulate hormone action. In Tribolium castaneum TcA cells, Trichostatin A, a histone deacetylase (HDAC) inhibitor, mimics juvenile hormone (JH) in inducing JH response genes (e.g., Kr-h1), suggesting that HDACs may be involved in JH action. To test this hypothesis,…
Birch tar production by Neanderthals—used for hafting tools—has been interpreted as one of the earliest manifestations of modern cultural behavior. This is because birch tar production per se was assumed to require a cognitively demanding setup, in which birch bark is heated in anaerobic conditions, a setup whose inherent complexity…
In early 2017, researchers managed to slip a flexible sliver of polymer next to a pig's heart. The device—placed between the heart and the fibrous wall that encases it, called the pericardium—squished and expanded with each contraction. It also converted the physical strain of its movement into electrical energy stashed…
Antibodies are indispensable tools in protein engineering and structural biology. Antibodies suitable for structural studies should recognize the 3-dimensional (3D) conformations of target proteins.

A popular strategy is to identify a small number of key collective variables and to introduce a bias potential that is…
We describe here the effects of metal complexation on the molecular recognition behavior of cavitands with quinoxaline walls. The nitrogen atoms of the quinoxalines are near the upper rim of the vase-like shape and treatment with Pd(II) gave 2:1 metal:cavitand derivatives. Characterization by 1H, 13C NMR spectroscopy, HR ESI-MS, and…
The chemistry of d-block metal–metal multiple bonds has been extensively investigated in the past 5 decades. However, the synthesis and characterization of species with f-block metal–metal multiple bonds are significantly more challenging and such species remain extremely rare. Here, we report the identification of a uranium–rhodium triple bond in a…
The conditions of methane (CH4) formation in olivine-hosted secondary fluid inclusions and their prevalence in peridotite and gabbroic rocks from a wide range of geological settings were assessed using confocal Raman spectroscopy, optical and scanning electron microscopy, electron microprobe analysis, and thermodynamic modeling. Detailed examination of 160 samples from ultraslow-…
The island rule predicts that small animals evolve to become larger on islands, while large animals evolve to become smaller. It has been studied for over half a century, and its validity is fiercely debated. Here, we provide a perspective on the debate by conducting a test of the island…
Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100…
Many ecosystems, from vegetation to biofilms, are composed of territorial populations that compete for both nutrients and physical space. What are the implications of such spatial organization for biodiversity? To address this question, we developed and analyzed a model of territorial resource competition. In the model, all species obey trade-offs…
Personality distinctions between entrepreneurs, nonfounder CEOs/leaders, and inventor employees have received limited attention, especially in innovative settings where they are working together. We surveyed these groups, along with other employees of innovative firms, at 4 locations of a prominent innovation and coworking center. Entrepreneurs display the greatest tolerance of risk,…
Organic electrosynthesis can transform the chemical industry by introducing electricity-driven processes that are more energy efficient and that can be easily integrated with renewable energy sources. However, their deployment is severely hindered by the difficulties of controlling selectivity and achieving a large energy conversion efficiency at high current density due…
Carbon dioxide (CO2) emissions from freshwater ecosystems are almost universally predicted to increase with climate warming. Glacier-fed rivers and lakes, however, differ critically from those in nonglacierized catchments in that they receive little terrestrial input of organic matter for decomposition and CO2 production, and transport large quantities of easily mobilized…
Crystallization by particle attachment (CPA) of amorphous precursors has been demonstrated in modern biomineralized skeletons across a broad phylogenetic range of animals. Precisely the same precursors, hydrated (ACC-H2O) and anhydrous calcium carbonate (ACC), have been observed spectromicroscopically in echinoderms, mollusks, and cnidarians, phyla drawn from the 3 major clades of…
Contrary to previous assumptions that most mutations are deleterious, there is increasing evidence for persistence of large-effect mutations in natural populations. A possible explanation for these observations is that mutant phenotypes and fitness may depend upon the specific environmental conditions to which a mutant is exposed. Here, we tested this…
A comparison of sequenced Agaricomycotina genomes suggests that efficient degradation of wood lignin was associated with the appearance of secreted peroxidases with a solvent-exposed catalytic tryptophan. This hypothesis is experimentally demonstrated here by resurrecting ancestral fungal peroxidases, after sequence reconstruction from genomes of extant white-rot Polyporales, and evaluating their
Cluster of differentiation 8 (CD8) is a cell surface glycoprotein, which is expressed as 2 forms, αα homodimer or αβ heterodimer. Peptide-loaded major histocompatibility complex class I (pMHC-I) molecules are major ligands for both forms of CD8. CD8αβ is a coreceptor for the T cell receptor (TCR) and binds to…
Despite pronounced genomic and transcriptomic heterogeneity in non–small-cell lung cancer (NSCLC) not only between tumors, but also within a tumor, validation of clinically relevant gene signatures for prognostication has relied upon single-tissue samples, including 2 commercially available multigene tests (MGTs). Here we report an unanticipated impact of intratumor heterogeneity (ITH)…
Many neurodegenerative diseases are characterized by the accumulation of abnormal protein aggregates in the brain. In Parkinson's disease (PD), α-synuclein (α-syn) forms such aggregates called Lewy bodies (LBs). Recently, it has been reported that aggregates of α-syn with a cross-β structure are capable of propagating within the brain in a…
Neuroscientists believe that immediately after a mammal is born, brain cells called microglia spring into action, pruning away connections between neurons. This may be a way for the brain to refine its neural networks. Until recently, neurobiologists had assumed the microglia worked by phagocytosis, reaching out a cup-shaped tendril to…
Genetically identical microbial cells respond to stress heterogeneously, and this phenotypic heterogeneity contributes to population survival. Quantitative analysis of phenotypic heterogeneity can reveal dynamic features of stochastic mechanisms that generate heterogeneity. Additionally, it can enable a priori prediction of population dynamics, elucidating microbial survival strategies. Here, we q
Lymphocytic choriomeningitis virus (LCMV) WE variant 2.2 (v2.2) generated a high level of the major mouse urinary protein: MUP. Mice infected with LCMV WE v54, which differed from v2.2 by a single amino acid in the viral glycoprotein, failed to generate MUP above baseline levels found in uninfected controls. Variant…
Citrus greening disease, also known as huanglongbing (HLB), is the most devastating disease of Citrus worldwide. This incurable disease is caused primarily by the bacterium Candidatus Liberibacter asiaticus and spread by feeding of the Asian Citrus Psyllid, Diaphorina citri. Ca. L. asiaticus cannot be cultured; its growth is restricted to…
Acinetobacter baumannii has rapidly emerged as a major cause of gram-negative hospital infections worldwide. A. baumannii encodes for the transport protein AceI, which confers resistance to chlorhexidine, a widely used antiseptic. AceI is also the prototype for the recently discovered proteobacterial antimicrobial compound efflux (PACE) family of transport proteins that…
Reading involves transforming arbitrary visual symbols into sounds and meanings. This study interrogated the neural representations in ventral occipitotemporal cortex (vOT) that support this transformation process. Twenty-four adults learned to read 2 sets of 24 novel words that shared phonemes and semantic categories but were written in different artificial orthographies….
Translational control plays a key role in regulation of neuronal activity and behavior. Deletion of the translational repressor 4E-BP2 in mice alters excitatory and inhibitory synaptic functions, engendering autistic-like behaviors. The contribution of 4E-BP2-dependent translational control in excitatory and inhibitory neurons and astrocytic cells to these behaviors remains unknown. To…
Great progress has been achieved in the research field of topological states of matter during the past decade. Recently, a quasi–1-dimensional bismuth bromide, Bi4Br4, has been predicted to be a rotational symmetry-protected topological crystalline insulator; it would also exhibit more exotic topological properties under pressure. Here, we report a thorough…
Complex and correlated quantum systems with promise for new functionality often involve entwined electronic degrees of freedom. In such materials, highly unusual properties emerge and could be the result of electron localization. Here, a cubic heavy fermion metal governed by spins and orbitals is chosen as a model system for…
Accurate annotation of plant genomes remains complex due to the presence of many pseudogenes arising from whole-genome duplication-generated redundancy or the capture and movement of gene fragments by transposable elements. Machine learning on genome-wide epigenetic marks, informed by transcriptomic and proteomic training data, could be used to improve annotations through…
The R2R3-MYB transcription factor FOUR LIPS (FLP) controls the stomatal terminal division through transcriptional repression of the cell cycle genes CYCLIN-DEPENDENT KINASE (CDK) B1s (CDKB1s), CDKA;1, and CYCLIN A2s (CYCA2s). We mutagenized the weak mutant allele flp-1 seeds with ethylmethane sulfonate and screened out a flp-1 suppressor 1 (fsp1) that…
Received wisdom argues that citizens more readily demand accountability from government for taxes than for nontax revenue from oil or foreign aid, giving rise to an important mechanism underlying the "resource curse," which posits that nontax revenue causes citizen quiescence and hampers government accountability. However, in developing countries, obfuscation through…
The approximate number system (ANS) has attracted broad interest due to its potential importance in early mathematical development and the fact that it is conserved across species. Models of the ANS and behavioral measures of ANS acuity both assume that quantity estimation is computed rapidly and in parallel across an…
An important feature of human cognition is the ability to flexibly and efficiently adapt behavior in response to continuously changing contextual demands. We leverage a large-scale dataset from Lumosity, an online cognitive-training platform, to investigate how cognitive processes involved in cued switching between tasks are affected by level of task…
A foundational question in the social sciences concerns the interplay of underlying causes in the formation of people's political beliefs and prejudices. What role, if any, do genes, environmental influences, or personality dispositions play? Social dominance orientation (SDO), an influential index of people's general attitudes toward intergroup hierarchy, correlates robustly…
We investigated the origins and interrelations of causal knowledge and knowledge of agency in 3-month-old infants, who cannot yet effect changes in the world by reaching for, grasping, and picking up objects. Across 5 experiments, n = 152 prereaching infants viewed object-directed reaches that varied in efficiency (following the shortest…
We present data from a nationally representative 2017 survey of American adults. For heterosexual couples in the United States, meeting online has become the most popular way couples meet, eclipsing meeting through friends for the first time around 2013. Moreover, among the couples who meet online, the proportion who have…
RETROSPECTIVE Correction for "Riccardo Giacconi (1931–2018)," by Harvey Tananbaum, Ethan J. Schreier, and Wallace Tucker, which was first published June 4, 2019; 10.1073/pnas.1902399116 (Proc. Natl. Acad. Sci. U.S.A. 116, 12587–12589). The authors note that on page 12587, right column, first full paragraph, line 4, "June 12, 1962" should instead appear…
Our modern interpretation of mermaids first came into view thanks to 19th-century European theater, according to new research. Mermaids can be larger than life or little, but regardless of stature, most people have basically the same idea of what they look like, says Tracy C. Davis, professor of performing arts at the School of Communication at Northwestern University. "What they may not realize,
On Monday, the European Space Agency (ESA) tweeted that it had to perform a " collision avoidance " maneuver to avoid a crash with one of SpaceX's Starlink satellites. SpaceX knew about the potential collision, Holger Krag, head of the ESA's Space Debris Office, told Forbes — but refused to do anything about it and wouldn't say why. According to the Forbes story, the U.S. military noticed that on
Studie ledet fra Sydvestjysk Sygehus i Esbjerg har som det første vist, at FFR-CT kan bruges til at forudsige, hvilke angina pectoris patienter der et år efter revaskularisering fortsat vil have symptomer
Selv moderat fysisk aktivitet giver en betydeligt lavere risiko i forhold til inaktive personer, viser meta-analyse, som Kim Wadt Hansen fra Bispebjerg Hospital har præsenteret på ESC.
Signifikant bedre overlevelse blandt de atrieflimrenpatienter, der genoptager deres blodfortyndende behandling efter indlæggelse for mavetarmblødning, end de, der ikke gør, viser kohorteundersøgelse præsenteret på ESC.
For the second straight year, Naomi Osaka was part of a tennis match that briefly took on a life of its own. Unfortunately for Osaka and her fans, that match didn't end with her hoisting a grand-slam singles trophy. It took place in the third round of the 2019 U.S. Open on Saturday, when she defeated the precocious Coco Gauff in straight sets and then took the unusual step of asking Gauff to part
People who suffered a financial, housing-related, or job-related hardship as a result of the Great Recession were more likely to show increases in symptoms of depression, anxiety, and problematic drug use, research shows. The declines in mental health that were still evident several years after the official end of the recession, but were obscured when examining trends in population-level data (e.g
