The team found that a diminutive theropod named Shuvuuia, had extraordinary hearing and night vision, sugge
Study: Residents left big metros during pandemic for family
1hCece Linder was living in a 770-square-foot apartment outside Washington, D.C., last spring when the area went into lockdown because of the coronavirus pandemic.
A rooted phylogeny resolves early bacterial evolution
1hA rooted bacterial tree is necessary to understand early evolution, but the position of the root is contested. Here, we model the evolution of 11,272 gene families to identify the root, extent of horizontal gene transfer (HGT), and the nature of the last bacterial common ancestor (LBCA). Our analyses root the tree between the major clades Terrabacteria and Gracilicutes and suggest that LBCA was a
Sex chromosome transformation and the origin of a male-specific X chromosome in the creeping vole
1hThe mammalian sex chromosome system (XX female/XY male) is ancient and highly conserved. The sex chromosome karyotype of the creeping vole ( Microtus oregoni ) represents a long-standing anomaly, with an X chromosome that is unpaired in females (X0) and exclusively maternally transmitted. We produced a highly contiguous male genome assembly, together with short-read genomes and transcriptomes for
The early origin of a birdlike inner ear and the evolution of dinosaurian movement and vocalization
1hReptiles, including birds, exhibit a range of behaviorally relevant adaptations that are reflected in changes to the structure of the inner ear. These adaptations include the capacity for flight and sensitivity to high-frequency sound. We used three-dimensional morphometric analyses of a large sample of extant and extinct reptiles to investigate inner ear correlates of locomotor ability and heari
Evolution of vision and hearing modalities in theropod dinosaurs
1hOwls and nightbirds are nocturnal hunters of active prey that combine visual and hearing adaptations to overcome limits on sensory performance in low light. Such sensory innovations are unknown in nonavialan theropod dinosaurs and are poorly characterized on the line that leads to birds. We investigate morphofunctional proxies of vision and hearing in living and extinct theropods and demonstrate
Reversible fusion and fission of graphene oxide-based fibers
1hStimuli-responsive fusion and fission are widely observed in both bio-organizations and artificial molecular assemblies. However, the design of a system with structure and property persistence during repeated fusion and fission remains challenging. We show reversible fusion and fission of wet-spun graphene oxide (GO) fibers, in which a number of macroscopic fibers can fuse into a thicker one and
Interfacial toughening with self-assembled monolayers enhances perovskite solar cell reliability
1hIodine-terminated self-assembled monolayer (I-SAM) was used in perovskite solar cells (PSCs) to achieve a 50% increase of adhesion toughness at the interface between the electron transport layer (ETL) and the halide perovskite thin film to enhance mechanical reliability. Treatment with I-SAM also increased the power conversion efficiency from 20.2% to 21.4%, reduced hysteresis, and improved opera
Direct observation of deterministic macroscopic entanglement
1hQuantum entanglement of mechanical systems emerges when distinct objects move with such a high degree of correlation that they can no longer be described separately. Although quantum mechanics presumably applies to objects of all sizes, directly observing entanglement becomes challenging as masses increase, requiring measurement and control with a vanishingly small error. Here, using pulsed elect
Quantum mechanics-free subsystem with mechanical oscillators
1hQuantum mechanics sets a limit for the precision of continuous measurement of the position of an oscillator. We show how it is possible to measure an oscillator without quantum back-action of the measurement by constructing one effective oscillator from two physical oscillators. We realize such a quantum mechanics–free subsystem using two micromechanical oscillators, and show the measurements of
Reversible oxygen migration and phase transitions in hafnia-based ferroelectric devices
1hUnconventional ferroelectricity exhibited by hafnia-based thin films—robust at nanoscale sizes—presents tremendous opportunities in nanoelectronics. However, the exact nature of polarization switching remains controversial. We investigated a La 0.67 Sr 0.33 MnO 3 /Hf 0.5 Zr 0.5 O 2 capacitor interfaced with various top electrodes while performing in situ electrical biasing using atomic-resolution
The impact of population-wide rapid antigen testing on SARS-CoV-2 prevalence in Slovakia
1hSlovakia conducted multiple rounds of population-wide rapid antigen testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in late 2020, combined with a period of additional contact restrictions. Observed prevalence decreased by 58% (95% confidence interval: 57 to 58%) within 1 week in the 45 counties that were subject to two rounds of mass testing, an estimate that remained rob
X-ray screening identifies active site and allosteric inhibitors of SARS-CoV-2 main protease
1hThe coronavirus disease (COVID-19) caused by SARS-CoV-2 is creating tremendous human suffering. To date, no effective drug is available to directly treat the disease. In a search for a drug against COVID-19, we have performed a high-throughput x-ray crystallographic screen of two repurposing drug libraries against the SARS-CoV-2 main protease (M pro ), which is essential for viral replication. In
Extreme altitudes during diurnal flights in a nocturnal songbird migrant
1hBillions of nocturnally migrating songbirds fly across oceans and deserts on their annual journeys. Using multisensor data loggers, we show that great reed warblers ( Acrocephalus arundinaceus ) regularly prolong their otherwise strictly nocturnal flights into daytime when crossing the Mediterranean Sea and the Sahara Desert. Unexpectedly, when prolonging their flights, they climbed steeply at da
Unearthing Neanderthal population history using nuclear and mitochondrial DNA from cave sediments
1hBones and teeth are important sources of Pleistocene hominin DNA, but are rarely recovered at archaeological sites. Mitochondrial DNA (mtDNA) has been retrieved from cave sediments but provides limited value for studying population relationships. We therefore developed methods for the enrichment and analysis of nuclear DNA from sediments and applied them to cave deposits in western Europe and sou
Fossil apes and human evolution
1hHumans diverged from apes (chimpanzees, specifically) toward the end of the Miocene ~9.3 million to 6.5 million years ago. Understanding the origins of the human lineage (hominins) requires reconstructing the morphology, behavior, and environment of the chimpanzee-human last common ancestor. Modern hominoids (that is, humans and apes) share multiple features (for example, an orthograde body plan
The coding and long noncoding single-cell atlas of the developing human fetal striatum
1hDeciphering how the human striatum develops is necessary for understanding the diseases that affect this region. To decode the transcriptional modules that regulate this structure during development, we compiled a catalog of 1116 long intergenic noncoding RNAs (lincRNAs) identified de novo and then profiled 96,789 single cells from the early human fetal striatum. We found that D1 and D2 medium sp

Too much, too little sleep linked to elevated heart risks in people free from disease
1hPeople who clock six to seven hours of sleep a night had the lowest chance of dying from a heart attack or stroke when compared with those who got less or more sleep, according to a new study.

But a new study suggests that fractures in the arm, wrist, leg and other parts of the body should also set off alarm bells. A fracture, no matter the location, indicates a general tendency to break a bone in the future at a different location.
