A new study by CEINT researchers provides the first evidence that nanoparticles can build up in a terrestrial food chain. Paul Bertsch and colleagues at the University of Kentucky have found that gold nanoparticles accumulate in tobacco plants and then concentrate further in tobacco hornworms ( [...]

The cleanliness of our water faces pressures from many directions. More factories mean more discharges, a growing population leads to more wastewater, and more runoff from lawns and farms carries pollutants into waterways. While there are many elements in water that may be harmful to people and the [...]

For centuries, the forces of weather and winds have sent more than 500 ships to the bottom of the Atlantic Ocean off North Carolina’s coast. Some were also brought down by another terrifying force -- German U-boat torpedoes during the Second World War.
Forty miles off the coast from Morehead City [...]

DURHAM, N.C. – The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health.
However, little is known which particles may be harmful. Part of the problem is determining exactly what a nanoparticle is.
A new [...]
