Signaling expert Forest White has begun applying his signature analytical techniques to investigate how environmental factors affect cancer development and progression. A recent modeling study challenges current thinking about carcinogenic compounds called polycyclic aromatic hydrocarbons (PAHs), which are released whenever organic matter is burned, including in wildfires, driving, and cooking. The MIT team’s findings, published in GeoHealth, suggest that the PAH historically used to inform regulatory standards may be inadequate for assessing global cancer risk.
