Alarming research from Macquarie University has revealed that chlorothalonil, one of the world’s most widely used agricultural fungicides, can drastically reduce the fertility of beneficial insects—even at concentrations commonly found on supermarket produce. The findings raise urgent concerns about the chemical’s role in accelerating the ongoing decline of insect populations worldwide, a phenomenon some scientists…

Enriched uranium is uranium processed to increase the concentration of the fissile isotope uranium-235 (U-235) beyond its natural abundance of 0.7%. Fissile refers to a material—specifically a nuclide—that can undergo nuclear fission when it absorbs a low-energy (thermal) neutron. This property is crucial because only fissile materials can sustain a self-sustaining nuclear chain reaction with…
