Facing facts

Facial-recognition systems have long been used at airport borders and on smartphones, but they are increasingly extending their reach into both public and private spaces. In this special issue, Nature probes the power — and the pitfalls — of the technology. One News Feature examines the inaccuracies and biases displayed by current systems. Another feature lifts the lid on ‘smart cities’ and how a lack of regulation and oversight could erode civil liberties. A third article discusses the growing concerns over the ethics of research studies in facial recognition. As governments and institutions seek to capitalize on this burgeoning technology, it is clear the field must take action to prevent abuse.

    An analysis of worldwide data finds that human mobility has a hierarchical structure. A proposed model that accounts for such hierarchies reproduces differences in mobility behaviour across genders and levels of urbanization.

    When determining whether gut microbes affect human health, it is hard to distinguish between a causal and a correlative relationship. Analysis of microbial links to human traits and habits correlated with disease offers a step forward.

    Understanding what contributes to the development of severe COVID-19 would be of great clinical benefit. Analysis of people in whom this occurred pinpoints a key role for the signalling pathway mediated by type I interferon proteins.

    Observations and stellar evolution models of a blue ring nebula and its central star (TYC 2597-735-1) suggest that the remnant star merged with a lower-mass companion several thousand years ago.

    A theoretical model in the form of a stochastic differential equation is proposed that describes, more accurately than previous models, the population evolution of cities, revealing that rare but very large interurban migration is a dominant factor.

    A model shows that human mobility is organized within hierarchical containers that coincide with familiar scales and that a power-law distribution emerges when movements between different containers are combined.

    Spectroscopic studies and theoretical calculations of the electrocatalytic oxygen evolution reaction establish that reaction rates depend on the amount of charge stored in the electrocatalyst, and not on the applied potential.

    Observations and air-quality modelling reveal that the sources of particulate matter and oxidative potential in Europe are different, implying that reducing mass concentrations of particulate matter alone may not reduce oxidative potential.

    Viral infection of the respiratory system induces exuberant fibroblast activity, resulting in extensive remodelling of the extracellular matrix and cytokine release, which promote immune cell infiltration of the affected area at the expense of respiratory function.

    Lung cancer

    Lung cancer kills about 2 million people annually — more than any other cancer. But the development of more-effective therapies and means of diagnosis provide some glimmers of hope.
