Clearing Up Murkiness in the Clean Water Act

A proposed rule change seeks to better define what waters are protected by the Clean Water Act, the law regulating pollution discharges into American water.

As written, the Clean Water Act currently applies to waters with a “significant nexus” to “navigable waters,” a bit of legalese that’s made it tough for regulators to crack down on pollution in some small tributaries.

This false color image taken on Sept. 19 captures the King Fire in California. Currently, over 92,960 acres have been burned since the blaze began on Sept. 13. The fire is 38% contained and was caused by an arsonist. Over 7,600 personal are working to battle the fire. In the picture, burned forest is red, unaffected forest is green, cleared forest is beige, and smoke is blue. (Image Credit: NASA)

Awesome! :D
"This works because the substance is not "ice" as in water, but a different substance called sodium acetate trihydrate. Normally solid sodium acetate was melted into a liquid that was then supercooled to below its melting point. In this state, adding nucleation sites, like the crystals on my hand, rapidly causes the rest of the sodium acetate to crystallize."
