Reactive pots and pans made of aluminum, cast iron, hammered steel, brass, or copper can react with some chemicals in foods, especially the acids and salts in sauces, brines, and marinades, and they can undergo a chemical reaction and create off flavors, and in rare cases, are toxic.

Starlink Plans to Send 42K Satellites Into Space. That Could Be Bad News for the Ozone

Satellites like the ones used for Starlink's internet service could be depleting the Earth's ozone layer when they're deorbited, according to a study funded by NASA and published in Geophysical Research Letters in June. 2024. When Starlink's satellites reach the end of their lives, they burn up in the Earth's atmosphere and leave behind small particles of aluminum oxide. These travel down into the ozone layer, which absorbs harmful ultraviolet radiation. Researchers from the University of South
