Who do you trust? Wild birds use social knowledge to avoid being deceived
21hMany species give deceptive warning calls, enabled by the high risk of ignoring them. In Siberian jays, a territorial, group-living bird, individuals give warning calls toward perched predators and mob them. However, intruding neighbors can emit these warning calls in the absence of predators to access food, but breeders often ignore these calls. Playback field experiments show that breeders flee
Improved estimates of preindustrial biomass burning reduce the magnitude of aerosol climate forcing in the Southern Hemisphere
21hFire plays a pivotal role in shaping terrestrial ecosystems and the chemical composition of the atmosphere and thus influences Earth's climate. The trend and magnitude of fire activity over the past few centuries are controversial, which hinders understanding of preindustrial to present-day aerosol radiative forcing. Here, we present evidence from records of 14 Antarctic ice cores and 1 central A

On the basis of t
Cortical response to naturalistic stimuli is largely predictable with deep neural networks
21hNaturalistic stimuli, such as movies, activate a substantial portion of the human brain, invoking a response shared across individuals. Encoding models that predict neural responses to arbitrary stimuli can be very useful for studying brain function. However, existing models focus on limited aspects of naturalistic stimuli, ignoring the dynamic interactions of modalities in this inherently contex
Real-time imaging of Na+ reversible intercalation in "Janus" graphene stacks for battery applications

The asymmetric functionalization allows reversible intercalation of Na + , as monitored by opera
Relations between absorption, emission, and excited state chemical potentials from nanocrystal 2D spectra

In this work, we integrate membraneless coacervate microdroplets, a prototype of artificial organelles, into a proteinosome to build hierarchical pro
Cost-effective implementation of the Paris Agreement using flexible greenhouse gas metrics
21hGreenhouse gas (GHG) metrics, that is, conversion factors to evaluate the emissions of non-CO 2 GHGs on a common scale with CO 2 , serve crucial functions in the implementation of the Paris Agreement. While different metrics have been proposed, their economic cost-effectiveness has not been investigated under a range of pathways, including those substantially overshooting the temperature targets.
Declining diversity of wild-caught species puts dietary nutrient supplies at risk

Here, we developed a simply fabricable tissue-engineered vascular microphysiological
Realization of a complete Stern-Gerlach interferometer: Toward a test of quantum gravity

Several theoretical studies have explained why a Stern-Gerlach interferometer is a formidable challenge. Here
Molecular mechanisms of metabotropic GABAB receptor function
21hMetabotropic -aminobutyric acid G protein–coupled receptors (GABA B ) represent one of the two main types of inhibitory neurotransmitter receptors in the brain. These receptors act both pre- and postsynaptically by modulating the transmission of neuronal signals and are involved in a range of neurological diseases, from alcohol addiction to epilepsy. A series of recent cryo-EM studies revealed cr
Control of neurogenic competence in mammalian hypothalamic tanycytes
21hHypothalamic tanycytes, radial glial cells that share many features with neuronal progenitors, can generate small numbers of neurons in the postnatal hypothalamus, but the identity of these neurons and the molecular mechanisms that control tanycyte-derived neurogenesis are unknown. In this study, we show that tanycyte-specific disruption of the NFI family of transcription factors ( Nfia/b/x ) rob
Conductance-stable liquid metal sheath-core microfibers for stretchy smart fabrics and self-powered sensing
21hHighly conductive and stretchy fibers are crucial components for smart fabrics and wearable electronics. However, most of the existing fiber conductors are strain sensitive with deteriorated conductance upon stretching, and thus, a compromised strategy via introducing merely geometric distortion of conductive path is often used for stable conductance. Here, we report a coaxial wet-spinning proces
Two ligand-binding sites in CO-reducing V nitrogenase reveal a general mechanistic principle
21hBesides its role in biological nitrogen fixation, vanadium-containing nitrogenase also reduces carbon monoxide (CO) to hydrocarbons, in analogy to the industrial Fischer-Tropsch process. The protein yields 93% of ethylene (C 2 H 4 ), implying a C–C coupling step that mandates the simultaneous binding of two CO at the active site FeV cofactor. Spectroscopic data indicated multiple CO binding event
Immunization with RBD-P2 and N protects against SARS-CoV-2 in nonhuman primates

Here, we developed a previously unknown subunit vaccine comprising the receptor binding domain (RBD) of the spike protein fused with the tetanus toxoid epitope P2 (RBD-P2) and tested its efficacy in rodents and
SARS-CoV-2 can recruit a heme metabolite to evade antibody immunity
21hThe coronaviral spike is the dominant viral antigen and the target of neutralizing antibodies. We show that SARS-CoV-2 spike binds biliverdin and bilirubin, the tetrapyrrole products of heme metabolism, with nanomolar affinity. Using cryo–electron microscopy and x-ray crystallography, we mapped the tetrapyrrole interaction pocket to a deep cleft on the spike N-terminal domain (NTD). At physiologi
Order from disorder in the sarcomere: FATZ forms a fuzzy but tight complex and phase-separated condensates with {alpha}-actinin
21hIn sarcomeres, α-actinin cross-links actin filaments and anchors them to the Z-disk. FATZ (filamin-, α-actinin-, and telethonin-binding protein of the Z-disk) proteins interact with α-actinin and other core Z-disk proteins, contributing to myofibril assembly and maintenance. Here, we report the first structure and its cellular validation of α-actinin-2 in complex with a Z-disk partner, FATZ-1, wh
