Study extends the number of antigenic peptides that can be produced from a single protein

Understanding medical research problems often relies on the direct, linear relationship between the sequence of a protein and the DNA encoding that protein. In fact, colinearity of DNA and protein sequences is thought to be a fundamental feature of the universal genetic code.

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.
