Chestnut trees are in danger due to an Exotic Fungus that entered this country over 100 years ago. With 4 billion trees being wiped out from this invasive fungus, Researchers are now using technology to keep this tree species alive.

The American chestnut tree was once a staple of U.S. landscapes, numbering over a billion. But by the 1950s, a fungus eliminated many of the species. Now, after 35 years of research, Professor William Powell has developed a blight-resistant American chestnut tree to restore the population.
In this episode of SciTech Now, a look into the scientific side effects of Superstorm Sandy; the development of a blight-resistant American chestnut tree; meet researchers in Tampa, Florida who are using mathematical modeling to help fight drug-resistant cancers; and a biologist studying seahorse pregnancy.
