This report finds that dietary restriction, the most extensively studied anti-aging intervention, can be mimicked by blocking food odour signaling and identifies a neural network of food perception that functions through serotonin and dopamine. | Continue reading
Rotaru et al. introduce a transparent crime forecasting algorithm that reveals inequities in police enforcement and suggests an enforcement bias in eight US cities. | Continue reading
Computational and experimental methods are bringing researchers closer to their goal of revealing exactly where in a cell or tissue each gene is expressed. | Continue reading
Moving fruit and vegetables in refrigerated vehicles is particularly emissions-intensive. | Continue reading
Two viruses that cause tropical diseases manipulate their hosts into emitting more of a mosquito-attracting molecule. | Continue reading
Russia is rich in palaeontological specimens, but its brutal war in Ukraine is threatening the research and relationships that help uncover the past. | Continue reading
Pharmacologist Janetti Francischi drew on folk wisdom and chemistry to turn used cooking oil into microbe-fighting soap during the COVID-19 pandemic. | Continue reading
A host of companies provide a remote, automated workforce for conducting experiments around the clock. | Continue reading

The stability of graphene-based field-effect transistors with amorphous aluminium oxide serving as the top-gate oxide can be improved by tuning the Fermilevel of the two-dimensional channel material such that it maximizes the energy distance between the charge carriers in the cha … | Continue reading
Artificial intelligence methods can help biodiversity conservation planning in a rapidly evolving world. A framework based on reinforcement learning quantifies the trade-off between the costs and benefits of area and biodiversity protection and achieves better solutions with empi … | Continue reading
Russia’s invasion of Ukraine has highlighted the need to improve energy security. | Continue reading
‘Microorganism’ is a misnomer when it comes to centimetre-long Thiomargarita magnifica. | Continue reading
Troubling data show how the pandemic has exacted an unequal toll, pushing tens of millions into poverty and having the greatest effects on already-disadvantaged groups. | Continue reading
Sixteen world leaders have now promised to protect the ocean. Researchers need to work with them to create and improve measurable indicators. | Continue reading
Self-regulation helps people to achieve their goals, and has been studied across modalities. Here, the authors present longitudinal evidence suggesting that common neural and behavioral measures of self-regulation derived from laboratory tasks do not predict everyday goal pursuit … | Continue reading
In-person conferences have typically resulted in a large carbon footprint while limiting inclusivity of those who can attend. This analysis uses the pandemic to gauge like-for-like environmental and demographic outcomes for virtual conference attendance. | Continue reading
Years of studies on abortion access foreshadow the negative economic and health effects ahead. | Continue reading
Coupling a two-step electrochemical system that converts CO2 to acetate with photovoltaics increases solar-to-food energy conversion efficiency, providing an alternative route to produce food from carbon dioxide and electricity, independent of biological photosynthesis. | Continue reading
The lineages’ rise seems to stem from their ability to infect people who were immune to earlier forms of Omicron and other variants. | Continue reading
Tumour cells spread mainly when the body is resting. | Continue reading
Using a participatory cognitive paradigm based on gaze contingency, Kanakogi et al. show that eight-month-olds increased their selective gaze to antisocial others to punish them, suggesting that preverbal infants engage in third-party punishment. | Continue reading
Meteorologists are forecasting a third consecutive year of La Niña. Some researchers say similar conditions could become more common as the planet warms. | Continue reading
African researchers have been warning about monkeypox outbreaks for years. As vaccines are deployed globally, they worry they will be left behind. | Continue reading
A study of patients with breast cancer and mouse models demonstrates that most circulating tumour cells are generated during the rest phase of the circadian rhythm, and that these cells are highly prone to metastasize. | Continue reading
BLOOM aims to address the biases that machine-learning systems inherit from the texts they train on. | Continue reading
Tumour cells spread mainly when the body is resting. | Continue reading
Researchers make ‘striking’ discovery that breast cancer cells are more likely to jump into the blood when people are resting. | Continue reading
Precision-engineered devices consisting of a linear array of ten quantum dots are used to realize both the trivial and topological phases of the many-body Su–Schrieffer–Heeger model. | Continue reading
Randomized trials are changing the way governments and aid organizations study — and deliver — measures to reduce inequality and poverty. | Continue reading
The loss of the sense of smell has been a hallmark symptom of COVID-19. The mechanisms behind SARS-CoV-2’s ability to interfere with this sense — as well as why variants such as Omicron do so less frequently — are becoming clearer. | Continue reading
Possible signature of a short-lived tetraneutron. | Continue reading
Pahor et al. find evidence across three experiments that the extent to which people improve in matrix reasoning as a result of N-back training is associated with their degree of improvement on working memory tasks similar to the training task. | Continue reading
Reasons included a lack of informed consent or ethics approval to share; misplaced data; and that others had moved on from the project. | Continue reading
Using a three-layer opto-electronic neural network, direct, clock-less sub-nanosecond image classification on a silicon photonics chip is demonstrated, achieving a classification time comparable with a single clock cycle of state-of-the-art digital implementations. | Continue reading

Experts say the country’s strong scientific performance is likely to be sustained in the coming years. | Continue reading
High resolution descriptions of social interactions and their neural correlates are lacking. Here the authors report a pipeline enabling fully automatic multi-animal tracking during social encounters, together with simultaneous electrophysiological recordings, and show this works … | Continue reading
