Scientists have now identified a way that cells respond to DNA damage through a process that targets proteins for disposal. The finding points to a new pathway for the development of cancer and suggests a new way of sensitizing cancer cells to treatment.

They are also the cells that are attacked by HIV, the devastating virus that causes AIDS and has infected roughly 40 million people worldwide. The virus slowly eats away at CD4 T cells, weakening the immune system.

In contrast, interventions based on cognitive approaches, which attempt to change knowledge, beliefs and attitudes, and are most commonly used by health care providers, did not improve physical activity.
