Arctic water

The Arctic Ocean didn’t become salty until a stretch of land that ran from Greenland (pictured here) to Scotland sank far enough beneath the sea, a new study finds.

frying egg

Caption: 

Many old-style nonstick frying pans relied on coatings containing PFOA or related perfluorinated compounds. Although there has been a move to alternative coatings, these perfluorinated pollutants live on in the environment. And that is driving new research aimed at removing them.
