A combination of advanced techniques at Oak Ridge National Laboratory helped researchers gain a better understanding of how some proteins attack bacteria. Colicins, a family of protein toxins, kill E. coli by crossing the bacterial membrane to exert their toxic effects. One family member, Colicin N,...

Changing the behavior of a material isn't big magic? it's nanoscale chemistry. Alejandro Lopez-Bezanilla used the computing power of Oak Ridge National Laboratory's Jaguar supercomputer, America's fastest, to study the effects of adding oxygen, sulfur and hydrogen to nanoribbons made of boron nitri...

By selectively applying different coatings, scientists have discovered they can influence the toxicity of particles on mouse cell lines from the lung and immune system. These findings, published in Langmuir, build on previous work that showed surface coatings can influence toxicity to bacteria. "The...
