'BeerBots' revolutionize brewing with speedy automation.

Researchers have developed self-propelled "BeerBots" that can speed up the brewing process by fermenting sugars faster and eliminating the need for filtration. The 2-mm-wide capsules contain active yeast, magnetic iron oxide nanoparticles, and sodium alginate from algae. The BeerBots can be easily separated from the final product with a magnet and can be used for up to three more wort fermentation cycles. The innovation could produce tasty brews faster and simplify the brewing process.
