Despite recent demonstrations of coherent spin-state transfer in arrays of spin qubits via exchange interaction, all-matter spin-state teleportation is still out of reach. Here the authors provide evidence for conditional teleportation of quantum-dot spin states, entanglement swa … | Continue reading
Current environmental impact mitigation neglects over-consumption from affluent citizens as a primary driver. The authors highlight the role of bottom-up movements to overcome structural economic growth imperatives spurring consumption by changing structures and culture towa … | Continue reading
During high-intensity exercise, muscles convert glucose to lactate, in a process that is energetically less efficient than respiration. Here the authors develop a computational model based on muscle proteomic data showing that bypassing mitochondrial complex I increases ATP produ … | Continue reading
More than 1,400 researchers have signed a letter calling on the discipline to stop working on predictive-policing algorithms and other models. | Continue reading
A cohort of asymptomatic patients infected with SARS-CoV-2 had significantly lower levels of virus-specific IgG antibodies compared to a cohort of age- and sex-matched symptomatic infected patients. | Continue reading
European particle-physics lab will pursue a 100-kilometre machine to uncover the Higgs boson’s secrets — but it doesn’t yet have the funds. | Continue reading
Habitat complexity influences the sensory ecology of predator-prey interactions. Here, the authors show that habitat complexity also affects the use of different decision-making paradigms, namely habit- and plan-based action selection. Simulations across habitat types show that o … | Continue reading
A periodicity of roughly 16 days is detected for the fast radio burst 180916.J0158+65, suggesting that the burst arises from a periodically modulated mechanism instead of a cataclysmic or sporadic process. | Continue reading
In a large trial, a cheap and widely available steroid cut deaths by one-third among patients critically ill with COVID-19. | Continue reading
The Seshat database has made it possible to reveal large-scale patterns in human cultural evolution. Here, Shin et al. investigate transitions in social complexity and find alternating thresholds of polity size and information processing required for further sociopolitical develo … | Continue reading
Research-optimized tools can take notes, dictate instructions and answer questions, allowing researchers to work hands-free. | Continue reading
The PlayStation head, in an interview with CNET, discusses the new PS5 design, launch games like Spider-Man, and pre-orders. | Continue reading
NASA’s New Horizons mission measures the distances of two stars from the outer reaches of the Solar System. | Continue reading
Bose-Einstein condensates studied in space. | Continue reading
A Bose–Einstein condensate prepared in low Earth orbit shows a free-expansion time greater than one second, demonstrating the advantages of a microgravity environment for such studies. | Continue reading
Developers hope that tools for processing natural language will help biomedical researchers and clinicians to find the COVID-19 papers that they need. | Continue reading
Using lipid residues absorbed in potsherds, the ages of pottery from various archaeological sites are determined and validated using sites for which the dates are well known from other methods. | Continue reading
RNA and DNA nucleosides might have emerged together on prebiotic Earth. | Continue reading
Maryam Mirzakhani, Fields medallist and Iranian national hero, is celebrated in an elegant documentary. | Continue reading
Primate inferotemporal cortex contains a coarse map of object space consisting of four networks, identified using functional imaging, electrophysiology and deep networks. | Continue reading
Northern China contains some of the world’s earliest farming societies. Here, authors use 55 ancient genomes to trace the genetic history of human migrations across northern China for the last 7500 years, and document genetic changes mirroring shifts in subsistence strategy. | Continue reading
Scientific reproducibility now very often depends on the computational method being available to duplicate, so here it is argued that all source code should be freely available. | Continue reading
Carbon nanothreads are promising for applications in mechanical energy storage and energy harvesting. Here the authors use large-scale molecular dynamics simulations and continuum elasticity theory to explore mechanical energy storage in carbon nanothreads-based bundles. | Continue reading
Retracted studies had relied on health-record analyses from a company that declined to share its raw data for an audit. | Continue reading
A Laughlin state made of composite matter–light particles. | Continue reading
SARS-CoV-2 came from an animal but finding which one will be tricky and time consuming. | Continue reading
Fast control over propulsion direction modulates interactions between self-propelled particles and opens new avenues for the design of active materials. Here, the authors present a light-active system that allows rapid direction reversal, leading to controlled fusion and fission … | Continue reading
The country is rapidly gaining on the United States in research, but problems could slow its rise: part 5 in a series on science after the pandemic. | Continue reading
Cryo-electron microscopy breaks a key barrier that will allow the workings of proteins to be probed in unprecedented detail. | Continue reading
Optically transparent electrodes with high electrical conductance are essential for the implementation of optoelectronics, but current technology performs poorly in the ultraviolet regime. Here, SrNbO3 is proposed as an alternative material due to its high figure of merit in the … | Continue reading
Babies born before 28 weeks of gestation are surviving into adulthood at higher rates than ever, and scientists are checking in on their health. | Continue reading
Cohort studies that follow populations over years have quickly pivoted to trace the pandemic’s physical, mental and social consequences. | Continue reading
A growing emphasis on do-it-yourself science is helping researchers to equip labs in resource-limited areas. | Continue reading
Analysts are tracking false rumours about COVID-19 in hopes of curbing their spread. | Continue reading
Analysing the space-time metric of quantum phenomena is complicated by the absence of a consistent theory of quantum gravity. Here, the authors show how to describe the space-time metric for multiple observers who are keeping time with quantum clocks, which interact gravitational … | Continue reading
Restricting movement on the basis of biology threatens freedom, fairness and public health. | Continue reading
To navigate pandemic trade-offs, policymakers need syntheses. | Continue reading
