New measurements to guide radiation therapy

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. The electrons produced by this process, known as secondary electrons, can themselves go on to wreak further havoc, causing even more dramatic changes. Investigators now report studies of the impact of secondary electrons on a model of DNA.

Steering electrical current with spinning light

Light can generate an electrical current in semiconductor materials. This is how solar cells generate electricity from sunlight and how smart phone cameras can take photographs. To collect the generated electrical current, called photocurrent, an electric voltage is needed to force the current to flow in only one direction.
