Ancient Mayan water filters stopped a lot--just not mercury poisoning

Popular Science

The civilization made the most of its technology, but everything has its limits. Mayan society often relied on cinnabar, a deep red pigment that got its hue from mercury sulfide. Breakthroughs, discoveries, and DIY tips sent six days a week. A trio of ancient reservoirs in present-day Guatemala is revealing both the strength--and limitations--of Mayan water science. While the civilization's purification techniques resulted in comparatively clean drinking sources, archaeologists say the unknowable consequences of a commonly used, deep-red pigment consistently subjected the Indigenous population to toxic mercury poisoning .


Rice cheese may be the next big thing

Popular Science

Early test batches contained 12 percent protein. Food scientists with the Arkansas Agricultural Experiment Station investigated proteins from three parts of a single rice cultivar for plant-based cheesemaking and discovered each source offered different qualities. Breakthroughs, discoveries, and DIY tips sent six days a week. There are a lot of non-dairy and vegan cheese alternatives on the market today. But while the tastes and textures of many of them almost pass for the real thing, they usually lack one major component: protein .


Meet Scotland's Whisky-Sniffing Robot Dog

WIRED

Inside Dewar's cavernous whisky warehouses, man's best mechanical friend--a Boston Dynamics robot dog with an ethanol sensor for a nose--is on the hunt for leaky barrels. Wooden barrels are what make the magic happen in your favorite bottle of whisky . At Bacardi Limited, the world's largest privately held spirits company, barrel leakage is a massive headache. Consider the company's Dewar's blended Scotch whisky brand (just one of the dozens it owns). Most of the time, Dewar's will have over 100 warehouses full of aging barrels of whisky, 25,000 casks in each one.
