<jats:title>Stem cells remember</jats:title> <jats:p> Tissue stem cells sense their surroundings, and this perception influences subsequent fate and function. Gonzales <jats:italic>et al</jats:italic> . observed that stem cells accumulate epigenetic memories of diverse environmental events (see the Perspective by Hoste). By wounding skin and monitoring the temporal steps involved in mobilizing stem cells of the hair follicle to repair the epidermis, the authors found that stem cells bear memories of their original niche, migration, encounters with inflammation, and adaptation to the new fate and tasks. During homeostasis, immigrant stem cells are functionally and transcriptionally analogous to native cells, but upon future assaults, they unleash discrete epigenetic memories to heighten physiological response and affect tissue fitness. —BAP </jats:p>

<jats:title>Easier said than done</jats:title> <jats:p> High-profile instances of police brutality in the last few years have brought attention to patterns of abuse that have existed since the inception of modern policing. There have been many calls for police reform, a process that in many countries has taken the form of increased police engagement with communities. Blair <jats:italic>et al</jats:italic> . report the results of a large-scale experiment testing the effectiveness of this approach across six countries in the Southern Hemisphere (see the Perspective by Tobon). They found that such community engagement did not increase trust in the police and it did not reduce crime. Improving relationships between police and community may require deeper structural changes before or in addition to approaches such as community policing. —SNV </jats:p>

<jats:p>Earlier this month, while the United Nations (UN) Climate Change Conference convened in Glasgow, countries also gathered at the Global Conference on Health and Climate Change to recognize the climate crisis as a global health crisis—a consequence of increased poverty, food and water insecurity, and infectious disease transmission, among other dangers. Unsurprisingly, both crises are worse in lower-income countries. These countries are also experiencing the greatest number of deaths and collateral damage from COVID-19.</jats:p>
