In quiet laboratories in College Station, Texas A&M researchers are pursuing ways to neutralize nerve gas, destroy toxins in our food supply, and prevent animal-disease contamination. Homeland Security tells the story of higher education's relentless efforts to keep our country safe.

Then, in High-Tech Warriors, watch robots communicate and cluster with one another on the UT San Antonio campus. They're learning to seek out hazards of our 21st-century world like improvised explosive devices — and will eventually take on jobs too dangerous for humans.

Meanwhile, Biosafety Level 4 tells a high-stakes health and medical detective story with wily antagonists like West Nile virus and Ebola. Researchers at UT Medical Branch in Galveston are committed to protecting our cities and states from rapidly mutating viruses that come from nature — or human design.
