Synthetic Lint Ends Up in Oceans
from Science News
Every time a garment made from polyester or other synthetic fabric goes through the wash, it sheds tiny plastic fibers. Thousands of them. It turns out that these fibers end up fouling coastal environments throughout the globe, a global research team finds.
Itsy bitsy plastic pellets, such as those used for their abrasive qualities in products like skin cleansers and paint removers, also turn up in coastal sand, a separate study reports. Like polyester lint, these micropellets also go down the drain, through water treatment plants and into coastal waters.
The mass that microplastic bits contribute to marine pollution is small, concedes Mark Browne of University College Dublin, who led the fiber study. But that doesn't mean their impact is benign, he adds.

VIDEO: How Hair Ice Grows
In 2013, American Scientist featured an article on odd ice formations on plant stems, including these curling ribbons of ice. One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
