Fine particulate matter (PM_2.5) – pollution particles measuring 2.5 micrometers or less – is released by human activity but also by natural sources like wildfires. These pollutants are a health risk for everyone, but pregnant people and unborn babies are particularly vulnerable. A new study shows that while total exposure to polluted air in the US has decreased over the past decades, almost two thirds of the days when unborn babies are exposed to unhealthy levels of PM_2.5 pollution are now due to wildfires. The team said this highlights that a shift of perspective is needed to efficiently target interventions and allocate resources to those most in need.

Relying on Artificial Intelligence (AI) in health care also carries a risk that existing racial and gender stereotypes will be reflected in the medical content it generates.
