Honey bees are incredibly important to the US food supply, of which about one-third relies on bees for pollination. A number of beekeepers have begun to see large-scale deaths and disappearances among the bee population.

On this week's TechKnow, contributor and science writer Kyle Hill travels to Minnesota and Washington to explore the phenomenon known as "colony collapse" and the devastating effects that the loss of honey bees could have on the American food industry.

Also On this edition of Techknow, Phil Torres explores the Amazon trying to understand the effects the environment there has on endangered Jaguars. The biggest threat being deforestation, clear-cutting large areas of the jungle ecosystem and shrinking the jaguars habitat.

And finally, Crystal Dilworth travels to California's Napa Valley to explore how vineyards are harnessing technology such as solar panels and weather stations to create better, more sustainable wine.
