Phys.org / Early warning for wine spoilage glows in the dark

Researchers built a living biosensor made of bacteria that lights up when it detects acetic acid, the main chemical signal that wine is starting to spoil. It works in real time, even in high-alcohol conditions, so wineries ...

Phys.org / Scientists reveal gold precipitation mechanism at pyrite-water interface

Gold is generally associated with pyrite (iron disulfide, FeS2), and pyrite-induced gold precipitation is critical to the formation of high-grade gold deposits. However, the role of pyrite in precipitating gold from fluids ...
