Extreme Cells Virginia Tech scientists are studying microorganisms that colonize environments that are extreme in terms of heat, cold, moisture, salinity, alkalinity, acidity, or radiation. Pesticides and the human immune system Has U.S. troops' exposure to pesticides increased soldiers' risk of disease? Smaller, better microchips Bioengineered fibrogen 'glue' a revolutionary 'bandage' for extreme bleeding cases Study of long-haul drivers’ sleep quality, performance underway

Geography providing a high-tech solution to excess use of pesticides The weevil that threatens sweet potatoes in Jamaica now has a new enemy to outwit, and it’s a high-tech foe. Genetic solution to malaria may be possible Somewhere in the workings of the genes of mosquitoes may be a key to disrupting the insect’s complex relationship with the parasites, a key that could break the cycle of transmission. Engineering undergraduates to design, build, operate research satellites The Virginia Tech student-built satellites will take scintillation measurements that could help scientists and engineers learn how to decrease the effects of instabilities in the ionosphere on GPS signals and may add to the body of knowledge about radio wave propagation.
