Citing concern about suspected threats to the health of humans and wildlife, the European Union’s Marie Curie European Industrial Doctorate program has awarded a €1.2 million research grant to four early-stage researchers from Asia, Australia and Europe to study the environmental effects of one of the most common types of flame retardants.

Even the most careful chosen meal can contain surprises.
