COVID-19 learning losses could deepen class gaps for years

COVID-19 school closures are projected to reduce educational attainment and weaken intergenerational mobility, with children from less advantaged backgrounds facing the greatest losses. The paper’s simulations suggest that unequal access to continued learning during the pandemic could deepen educational inequality and reverse mobility gains, especially in the absence of remedial recovery measures.

Survey: Public awareness of alcohol-related cancer risk remains unchanged

Public awareness of the link between drinking alcohol and elevated cancer risk remains unchanged since February 2025, with over half of Americans saying that regularly consuming alcohol increases your chances of later developing cancer, according to a new survey by the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

Researchers use AI to reveal the true scale of COVID-19 mortality in the US

A machine learning model applied to US death certificate data estimated that over 155,000 COVID-19 deaths were unrecognized between March 2020 and December 2021, suggesting total mortality was about 19% higher than official counts. These undercounted deaths disproportionately affected marginalized populations, including racial minorities, lower-income groups, and residents of the Southern United States.
