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.
Twenty-five experts have issued a warning about the potentially cataclysmic consequences of the rapidly shrinking insect population, reports The Guardian. In a two-part article for Biological Conservation, the scientists wrote: “The current [insect] extinction crisis is deeply worrisome. Yet, what we know is only the tip of the iceberg.We know enough to act immediately. Solutions […]
Scientists say 20.75º C logged at Seymour Island is ‘incredible and abnormal’
Snowfall in Baghdad, for the second time in a decade. What a strange sight.
“It’s better to have it and not need it than to need it and not have it.” – “Lonesome Dove,” Larry McMurtry If the past few months have taught us anything, it’s that we need to be prepared now more than ever. Emergency situations can happen quickly and there’s no telling when you may need […]
Just as in almost any industry that seeks high-demand, well-trained workers, certification often becomes key. For project managers, that means anyone who’s serious about serving in that role with a respected company knows they’re going to need the seal of approval in one of the field’s most recognized methodologies before they stand much of a […]
Popping a new battery in a smoke detector or adding salt to your water softener are easy fixes. But if you run into trouble or a necessary repair in a cramped, tight place, sometimes with no obvious fix or easy access, it can be a pretty frustrating exercise. Since flying blind is the absolute worst, […]
