To power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the wind isn’t blowing and the sun isn’t out.

A new UC San Francisco study has shown that a cancer-killing (“oncolytic”) virus currently in clinical trials may function as a cancer vaccine – in addition to killing some cancer cells directly, the virus alerts the immune system to the presence of a tumor, triggering a powerful, widespread immune response that kills cancer cells far outside the virus-infected region.
