The Long-Lost Tale of an 18th-Century Tsunami, as Told by Trees

And timber don’t overlook. In the 1990s, researchers recognized a “ghost forest” of lifeless cedars close to the Washington coast; tree-ring relationship confirmed that they’d certainly died in 1700. But Black and Dziak sought out timber that skilled the tsunami—and survived. The rings of these timber may include proof of the stress brought on by …

Baby Poop Is Loaded With Microplastics

All instructed, PET concentrations have been 10 instances increased in infants than in adults, whereas polycarbonate ranges have been extra even between the 2 teams. The researchers discovered smaller quantities of each polymers within the meconium, suggesting that infants are born with plastics already of their techniques. This echoes earlier research which have discovered microplastics …

In a Tiny Arctic Town, Food Is Getting Harder to Come By

It’s straightforward to assume that sea ice would affect solely the ocean, however there are lots of power exchanges between the terrestrial and marine ecosystems. Seabirds, for instance, nest on an island, forage within the water, after which come again on the land, the place their guano fertilizes vegetation. The tundra, as a low-productivity space, …
