Many Selves, One Body

Dissociative identity disorder (DID) is a condition in which a person has two or more distinct personalities that regularly take control of their behavior. Traditionally, the goal of treating this condition has been to "integrate" all the personalities into one core self. But psychotherapist and anthropologist Rebecca Lester took a different approach with a young woman named Ella. Their therapy got Ella's 12 personalities to work together as a team.

Why this is inspiring: Western cultures tend to think of the self as a bounded, unique, more or less integrated center of emotional awareness. But many cultures and some neuroscientists see the self as a collection of different minds or souls. Embracing Ella's distinct personalities rather than eradicating them allowed for a more peaceful coexistence, a community of sorts.

Did it work? In the years following treatment, Ella (whose name has been changed to protect her identity) graduated college, established a career, fell in love and had a child of her own. Her many parts still exist, sometimes just below the surface, and they use their different skills to help Ella navigate the world, she says. Listen to this podcast to hear more about this story.

HIV Milestone

After 20 years a massive U.S. government effort to combat the HIV/AIDS epidemic recently reached a new milestone: the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) successfully delivered antiretroviral therapy to more than 20 million people globally. The program has funneled some $110 billion into 50 countries, providing health-care infrastructure and antiretroviral therapies. 

Why this matters: An HIV/AIDS diagnosis is no longer a death sentence. The program has indirectly improved nutrition and treatment of other diseases like tuberculosis and Ebola, especially in Africa, which benefited from the influx of medical care and resources.

What the experts say: New prophylactic therapies help prevent the spread of the virus, and new treatments in development that use HIV-resistant stem cells have cleared the virus from several patients. But "certainly that's still a work in progress," says Phyllis Kanki, professor of immunology at Harvard University.

In New York City, the sun was shrouded this morning as it rose in a hazy, smoky sky. Air quality measurements are among the worst on record because of high levels of particulate matter billowing in with smoke from wildfires in Canada. Fine particles have a diameter of 2.5 microns or smaller—tiny enough to travel deep into the respiratory system.
