Phase curves from a sample of 12 hot Jupiters show that this type of planet keeps the same nightside temperature (~1,100 K) regardless of the irradiation they receive from their star. This effect is due to an optically thick layer of the same species of clouds on the nightside he … | Continue reading

Until appropriate safeguards are in place, we need a moratorium on biometric technology that identifies individuals, says Kate Crawford. | Continue reading
Quantifying entanglement in a large quantum system requires an intractable number of measurements. Here, the authors demonstrate a method for certifying entanglement from extremely undersampled data by combining a new quantitative entanglement witness with an adaptive sampling pr … | Continue reading
The treatment for bipolar disorder was discovered through an unlikely route. Douwe Draaisma praises an account of it. | Continue reading
Geometric analysis and constrained optimization algorithms allow for the design of kirigami patterns that can be deployed into any two- or three-dimensional shape. | Continue reading
Colleagues of Alan Cooper, who has been suspended as leader of the prestigious Australian Centre for Ancient DNA, describe a toxic work environment. | Continue reading
Wunderkind gene-editing tool used to trigger smart materials that can deliver drugs and sense biological signals. | Continue reading
Proxies of deep circulation suggest that the onset or strengthening of the Atlantic meridional overturning circulation occurred at the Eocene-Oligocene Transition. The authors show, using a paleoclimate model of the late Eocene, that a shift from Pacific to Atlantic overturning c … | Continue reading
Activity of the PIEZO1 ion channel affects a defence response. | Continue reading
The evolution of complex animal life in the Cambrian period is thought to be related to oxygenation of the Earth System, however the timing, magnitude and mechanism of this oxygenation event remain uncertain. Here, the authors use a biogeochemical model which links tectonic CO2 d … | Continue reading
Time has a fundamentally different character in quantum mechanics and in general relativity. Here, the authors consider a thought experiment where a massive body in a spatial superposition leads to entanglement of temporal orders between time-like events, resulting in a violation … | Continue reading
Two Japanese scientists supply hundreds of laboratories with a prized gem — and are now among the world’s most published researchers. | Continue reading
Recent gains in artificial neural networks rely heavily on large amounts of training data. Here, the author suggests that for AI to learn from animal brains, it is important to consider that animal behaviour results from brain connectivity specified in the genome through evolutio … | Continue reading

Network analysis informs policies to tackle hate groups online. | Continue reading
The country’s artificial-intelligence research is growing in quality, but the field still plays catch up to the United States in terms of high-impact papers, people and ethics. | Continue reading
Biomarkers that predict mortality are of interest for clinical as well as research applications. Here, the authors analyze metabolomics data from 44,168 individuals and identify key metabolites independently associated with all-cause mortality risk. | Continue reading
Some highly cited academics seem to be heavy self-promoters — but researchers warn against policing self-citation. | Continue reading
Radioastronomers look to hydrogen for insights into the Universe’s first billion years. | Continue reading
If the country’s main science-funding agency doesn’t get more cash soon, young researchers will stop getting paid. | Continue reading
In this Perspective, the authors present a framework, context and guidelines for accelerating the translation of machine-learning-based interventions in health care. | Continue reading
Phase curve measurements for the small (1.3 Earth radii) terrestrial exoplanet LHS 3844b show absence of a thick atmosphere, in agreement with theoretical predictions. | Continue reading
Since the early 1980s, remotely sensed data has shown the Earth to be slowly greening. Climate change, CO2 fertilization and land-use change are competing explanations. Using satellite data from 2000–2017, this study finds striking greening of both China and India, driven primari … | Continue reading

The technical and economic viability of renewable energy (RE) based energy system is understudied. Here the authors utilized a LUT Energy System Transition Model to indicate that a carbon neutral electricity system can be built in all global regions in an economically feasible wa … | Continue reading
A framework that includes inequality shows that extreme inequality prevents cooperation, but overall welfare is maximized when endowments and productivities are aligned such that more-productive individuals receive higher endowments. | Continue reading
