Nuclear talks

Secretary of State John Kerry returned to Switzerland early this morning to conclude high wire negotiations with Iran about a framework deal to halt its nuclear program in exchange for sanctions relief. CBS News correspondent Margaret Brennan reports U.S. diplomats are optimistic that there is now a visible "path" to reach what would be a historically significant arms control agreement by the self-imposed Tuesday deadline.

Losing ground

In just 15 years, the American workforce has become increasingly diverse, yet gender-based and racial trends remain stubbornly entrenched. Since 2001, women workers have lost share of employment in 48 out of the 50 highest-paying jobs in the country, even though more women are in the workforce today and more are graduating from college. CBS News MoneyWatch reports on why.

Yoga mindset

Before Mark Bertolini became CEO of Aetna, he almost died on a family ski trip. While recovering, he looked for alternative ways to manage pain. "CBS This Morning" co-host Gayle King reports Bertolini found healing in yoga and meditation, and that inspired him to bring a new mindset to one of the nation's largest health insurance companies.
