Purdue University researchers built this bizarre crawling robot baby to study how real infants kick up dirt and bacteria from carpet that they then inhale. Engineer Brandon Boor and his colleagues ran the robot over carpet samples removed from people's homes and then analyzed the particulates that were stirred up. Turns out that the particle concentration is as much as 20 times greater than higher up in the room where we adults breathe. That isn't necessarily bad though, Boor says.
"Many studies have shown that inhalation exposure to microbes and allergen-carrying particles in that portion of life plays a significant role in both the development of, and protection from, asthma and allergic diseases," says Boor, an assistant professor of civil engineering and environmental and ecological engineering. "There are studies that have shown that being exposed to a high diversity and concentration of biological materials may reduce the prevalence of asthma and allergies later in life."

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.

Nothing like going to a tropical dive spot known to be "untouched" by humans, only to find a giant plastic garbage patch stretching as far as the eye can see. The Doobie Brothers music adds a nice touch. Read the rest
Indiana’s Yellowwood State Forest is a scenic forest that Indiana's Department of Natural Resources put up for sale. But after conservationists gathered $150,000 to preserve the forest for another 100 years, the government sold it to a local logging company for $108,785. Read the rest

Canada's filthy tar sands are the world's most carbon-intensive petroleum source, and in the boom years, they flooded the country with so much filthy money that the country spent a decade making war on science and trashing democratic fundamentals in a bid to sustain the tar-sands bubble.

Much of the UK's system of laws and "unwritten constitution" derives from EU law, so with Brexit inexorably advancing, the UK has to pass a whole raft of parallel legislation that will replace the EU laws with UK versions, lest there be a "legal black hole" the day after Brexit.

In 1997, ecologists Daniel Janzen and Winnie Hallwachs convinced a Costa Rican orange juice maker to to dump their waste peels in a clear-cut abandoned pasture that was in a national park. Twenty years later, the enriched soil nourishes tropical forest again, according to a new report. Read the rest
