Proteins may behave differently in natural environments

When in an environment similar to that in which they exist naturally, proteins and multiprotein assemblies may demonstrate actions or dynamics different than those they exhibit when in the static form in which they are most often studied, said researchers at Baylor College of Medicine in a report in the current issue of the journal Structure.

New screening method shows how nanoparticles interact with human cells

Scientists at the Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. Using this new method, the investigators have been able to visualize how human cells interact with some specific types of carbon nanoparticles.
