  Video: Ingenious Video 9: The World’s Smallest Water Treatment Plant Comes in a Packet Mark as Favorite (1 Favorite)

  About 800,000,000 people worldwide – that’s almost one in ten, more than the population of the U.S. – don’t have reliable access to clean water. Using a technology first developed to reuse dirty laundry water, scientists have developed a water treatment plant the size of a teabag. Inside, a potent chemical triple-threat removes microbes, heavy metals, silt and dirt to produce clean, safe water one bucket at a time.

  Video: Ingenious Video 10: Oversexed Moths are Ruining Apples for Everyone Mark as Favorite (2 Favorites)

  Codling moths may look harmless, but their larvae wreak havoc in orchards, burrowing into fruit and eating them from the inside out. Pesticides have always been the solution to the old “worm in the apple” problem, but pesticides kill all the insects in the field, even the good ones. Instead of pesticides, farmers may soon use pheromones, those scented chemical messages animals release at mating time. Spreading synthetic, species-specific pheromones keeps male codling moths from finding females to mate with. No mating means no eggs, no larvae, and no more bad apples. Scaling up agricultural pheromones has proved difficult, but innovative approaches to pheromone production (using yeast cells) and distribution (with the help of customized weather stations) are starting to make it happen.

This episode investigates how the larvae of codling moths wreak havoc in orchards—burrowing into fruit and eating them from the inside out. Scientists are developing synthetic, species-specific pheromones as an alternative to pesticides. Pheromones are scented chemical messages that animals release at mating time and can help to prevent male codling moths from finding females to mate with. No mating means no eggs, no larvae and no more bad apples!
