The hinge enables insects to control their wing movements, but how it works is hard to study. Multidisciplinary research, using imaging and machine-learning methods, now sheds light on the mechanism that underlies its operation.
The sympathetic nervous system, which enables the fight-or-flight response, was thought to be present only in jawed vertebrates. Analysis of a jawless vertebrate suggests that this system might be a feature of all animals with a spine.
Paring down the astronomical complexity of the protein-folding problem, plus Isaac Newton’s ambiguous use of the word ‘axiom’, in the weekly dip into Nature’s archive.
An ambitious investigation has analysed discourse on eight social-media platforms, covering a vast array of topics and spanning several decades. It reveals that online conversations increase in toxicity as they get longer — and that this behaviour persists despite shifts in platforms’ business models, technological advances and societal norms.
Political candidates are increasingly using ‘softfakes’ — obviously AI-generated content — to boost their campaigns and whitewash their reputation. Plus, AI now beats humans at basic tasks and algorithm learns to nudge human gaming partner.
Everyone who reviews a manuscript should answer a transparent set of questions, to ensure that scientific literature is subject to reliable quality control.
We introduce strong tailored light-wave-driven time-reversal symmetry breaking in monolayer hexagonal boron nitride, realizing a sub-laser-cycle controllable analogue of the topological model of Haldane and inducing non-resonant valley polarization.
