ETH Zurich researchers developed a "living ink" for 3D printers that's made from bacteria, nutrients, and a polymer gel. In a small scale demonstration, they printed a small 3D lattice of the material that cleaned up a beaker of contaminated water. From Science News:
Lattices packing various types of chemical-hungry bacteria could create special water filters or help clean up oil spills. And unlike free-floating bacteria, cells locked in a 3-D grid could be plucked out of cleaned-up water and reused somewhere else....
Bacteria-filled 3-D prints could also produce bacterial cellulose — a gelatinous substance used for dressing wounds. Bacterial cellulose is typically grown in sheets, but “imagine if you have a burn on your elbow,” (materials scientist Manuel) Schaffner says. “You try to wrap flat, wet tissue around this area, it’s prone to detach.” Swathes of cellulose grown on 3-D printed structures could precisely match the contours of specific body parts, curbing the risk of contaminants getting trapped under wrinkles in the cellulose or the material peeling off.

About 10% of plastic ocean pollution is ghost nets, the countless lost or abandoned fishing nets that maim and kill marine life. Jenga Ocean, made of recycled nets, tries to raise awareness, recycle recovered nets, and raise funds to help end this type of pollution. Via Bureo:
Al Shabab (previously) is an Al Qaeda-affiliated terrorist group whose use of child soldiers, brutal murder, and attacks targeted at civilians have allowed them to carve out a jihadi-controlled territory in Somalia.
