A team of researchers from Rice University, Carnegie Mellon University and other leading global institutions has outlined a bold new roadmap for harnessing heterogeneous catalysis to destroy per- and polyfluoroalkyl substances (PFAS), the so-called “forever chemicals” that have contaminated water supplies worldwide.

A landmark study exploring Canadians’ consumption of chips, frozen pizzas, breakfast cereals and other ultra-processed foods typically loaded with fat, sugar and additives has confirmed these foods are directly and significantly linked to poor health outcomes.
