Slosh and Berm: Building Sand Barriers off Louisiana's Coast to Hold Back Oil Spill Has Low Probability of Success

Articles from Scientific America - Tue, 06/08/2010 - 15:01

In an effort to stem the tide of oil washing ashore in Louisiana, small "berms" of sand now plug gaps in barrier islands along the coast. Such structures are intended to provide a barrier to oil penetrating into marshes and other wetlands, where it can persist for decades. Already, more than 250 kilometers of coastline have been touched by the output of the ongoing oil spill, which has now spewed as much as 170 million liters of petroleum into the Gulf of Mexico.

Butterfly Wings Scale Copies Could Fight Forgers

Articles from Scientific America - Mon, 06/07/2010 - 14:24

Counterfeiters and money minters constantly try to outsmart each other. But money could become much harder to forge--thanks to butterfly wings.

Butterflies that flit through tropical forests often have brightly colored wings that irridesce in the sun. But it’s not pigments that create those eye-catching shades. It’s microscopic structures on the insects’ wings that reflect the light.
