Earth-based concretes are more environmentally friendly than traditional concrete compositions, but they often require some Portland cement to stabilize the mixture. Bio-based stabilizers could overcome the need for Portland cement, and researchers at Columbia University investigated the potential of the common food additive xanthan gum for this purpose.

Removing PFAS from aquatic environments remains a key challenge in our efforts to eliminate these toxic “forever chemicals” from the environment. University of Bath researchers investigated the potential of indium oxide to remove PFAS through adsorption, and their 3D-printed ceramic monoliths successfully adsorbed up to 75% of contaminants in initial tests.

Much remains unknown about deep-sea ecosystems. In a recent open-access paper, an international team of researchers propose a preliminary hypothesis that polymetallic nodules may play a role in deep-sea oxygen production. If confirmed upon further investigation, this discovery would have implications for deep-sea mining activities.

PFAS chemicals traditionally are believed to enter the body mainly through ingestion via food or drinking water or by being breathed in. But researchers at the University of Birmingham have now confirmed PFAS can permeate through skin—demonstrating the risk of exposure to these harmful chemicals.
