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.
Farming is undergoing a quiet but radical transformation as machine learning and automation innovations reduce waste. One especially promising new technology targets individual weeds.
CFC-11 was phased out under 1987's Montreal Protocol and the immediate halt of its usage has done much to reverse ozone depletion in the years since; but since 2012, atmospheric levels of CFC-11 have risen by 25%, eroding the still-healing ozone layer and suggesting that someone, somewhere, has started manufacturing the substance again.
South Georgia Island (population 20), due east off the tip of South America, had no rodents until 18th-century sailing ships accidentally introduced them. After seven years of work, the island is now rodent-free, allowing native birds to recover.
