A new way to stretch DNA

Researchers have recently developed a new way to controllably manipulate materials, in this case biomolecules that are too small to see with the naked eye. By stretching molecules like DNA and proteins, scientists can find out important information about the structure, chemical bonding and mechanical properties of the individual molecules that make up our bodies. This understanding could shed light on diseases like cancer and ALS. The new technique is called acoustic force spectroscopy (AFS). —> Read More
