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.
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.
A pioneering ‘connectomics’ collaboration has successfully reconstructed one cubic millimetre of brain tissue, but researchers are still just scratching the surface of the complexity it contains.
Results from the telescope could help to end a long-standing disagreement over the rate of cosmic expansion. But scientists say more measurements are needed.
