Menstrual cycle tracking apps pose risks to users, according to a report published by the Minderoo Centre for Technology and Democracy at the University of Cambridge (United Kingdom). These apps collect intimate data about their users' physical and mental health and reproductive decisions, which can be exploited for commercial or legal purposes, the report warns.
The budget cuts affecting scientific activity in countries such as the United States and the fragility of centralised systems make decentralised and collaborative models a necessity. Science, intrinsically global, requires structures that can withstand local pressures. In this situation, Europe has the opportunity - and the duty - to lead a new paradigm where data is free, secure and accessible.
A new web-based tool analyzes major cities like Tokyo, Paris, Atlanta or Barcelona to see how close they are to the 15-minute city concept, where residents take less than those minutes to access essential services by foot, bike, or public transport. According to the study, published in Nature Cities, few cities fit this concept. The tool, which is freely accessible and uses data from 10,000 cities sourced from the open-source packages GeoPandas and OpenStreetMap, could be useful for developing action plans and estimating how viable it is to transform certain cities to follow this model.
