New smartphone can help people with mental health problems

Brooding in your apartment on Saturday afternoon? A new smart phone intuits when you're depressed and will nudge you to call or go out with friends. It's the future of therapy at a new Northwestern University Feinberg School of Medicine center where scientists are inventing web-based, mobile and virtual technologies to treat depression and other mood disorders. The phone and similar projects bypass traditional weekly therapy sessions for novel approaches that provide immediate support and access to a much larger population.

Scientists study organ development in mice to unravel how breast cancers develop in people

Reviving a theory first proposed in the late 1800s that the development of organs in the normal embryo and the development of cancers are related, scientists at the Salk Institute for Biological Studies have studied organ development in mice to unravel how breast cancers, and perhaps other cancers, develop in people. Their findings provide new ways to predict and personalize the diagnosis and treatment of cancer.
