Recent studies have shown T cell reactivity to SARS-CoV-2 in 20–50% of unexposed individuals; it is speculated that this is due to T cell memory to common cold coronaviruses. Here, Crotty and Sette discuss the potential implications of these findings for disease severity, herd im … | Continue reading
Economists welcome the chance to see whether giving people cash to spend however they choose improves livelihoods. | Continue reading
The pandemic is prompting some early-career researchers to rethink their hopes for a university post. | Continue reading
The classification of complex organisms is in chaos. Stephen T. Garnett and Les Christidis propose a solution. | Continue reading
Feat enables researchers to study — and perhaps treat — deadly diseases. | Continue reading
The United Arab Emirates’ Hope orbiter is the Arab world’s first interplanetary spacecraft — and has jump-started science in the country. Will the momentum last? | Continue reading
Genomic analyses of DNA from modern individuals show that, about 800 years ago, pre-European contact occurred between Polynesian individuals and Native American individuals from near present-day Colombia, while remote Pacific islands were still being settled. | Continue reading
Finding that some Polynesians carry genetic ancestry from South America supports long-held theory that ancient populations met and interbred. | Continue reading
The funding agency has taken action in 16-20 cases where foreign ties were not properly reported. | Continue reading
Genetic material is being collected from men across the country to help solve crimes, but researches worry the data will be misused. | Continue reading
Those who could be exploited by AI should be shaping its projects. | Continue reading
Mini and micro light-emitting diodes (LEDs) could move to the centre-stage of display screen technologies once they mature. Shin-Tson Wu of the University of Central Florida and colleagues analysed the pros, cons, and future prospects of the latest display screen technologies, es … | Continue reading
Peter Rowlett introduces seven little-known tales illustrating that theoretical work may lead to practical applications, but it can't be forced and it can take centuries. | Continue reading
The ‘quasiparticles’ defy the categories of ordinary particles and herald a potential way to build quantum computers. | Continue reading

Observations of TOI-849b reveal a radius smaller than Neptune’s but a large mass of about 40 Earth masses, indicating that the planet is the remnant core of a gas giant. | Continue reading
Effects of vacuum fluctuations in a gravitational-wave detector. | Continue reading
A memory device is proposed that uses a dynamical modification of the stacking order of few-layer WTe2 to encode information. The change in stacking modifies both the Berry curvature and the Hall transport, allowing two states to be distinguished. | Continue reading
Remotely controlled experiments are the way forward. | Continue reading
Three studies showing large DNA deletions and reshuffling heighten safety concerns about heritable genome editing. | Continue reading
Evidence from tissue studies and some people with COVID-19 shows that the virus damages insulin-producing cells. | Continue reading
China’s New Generation Artificial Intelligence Development Plan was launched in 2017 and lays out an ambitious strategy, which intends to make China one of the world’s premier AI innovation centre by 2030. This Perspective presents the view from a group of Chinese AI experts from … | Continue reading
Personality traits help to explain why some people and not others hoarded a humdrum product in the face of a deadly virus. | Continue reading
A prebiotic synthesis of the purine DNA nucleosides (deoxyadenosine and deoxyinosine) in which the pyrimidine RNA nucleosides (cytidine and uridine) persist has implications for the coexistence of DNA and RNA at the dawn of life. | Continue reading
Chip-based frequency combs promise many applications, but full integration requires the electrical pump source and the microresonator to be on the same chip. Here, the authors show such integration of a microcomb with < 100 GHz mode spacing without additional filtering cavitie … | Continue reading
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
