In his 2001 graduation speech to medical students at Brown University, doctor and activist Paul Farmer said while science and technology are the heart of modern medicine, "you must add the soul." Farmer, the co-founder of Partners in Health, which brings modern health care to the poor, has focused much of his career on that hands-on approach to medicine, living among and treating locals in Haiti, Peru, Russia and other countries. Farmer joins us to talk about his advice to future doctors and his new book, "To Repair the World," a collection of his speeches on global health and social justice.

A New York judge fined an Airbnb user $2,400 this week for renting out a room in his apartment, arguing the three-night rental violated the city's "illegal hotel" laws. The popular San Francisco-based online site that allows users to offer their homes as temporary rentals has also been accused of disrupting local housing markets and failing to charge city taxes. Forum discusses what the ruling may mean for Airbnb and its users locally, and for other participants in the so-called share economy.

A U.S. Senate subcommittee this week accused Apple of exploiting loopholes and creating stateless foreign subsidiaries to avoid paying $9 billion in U.S. taxes last year.

When photographer Bryant Austin came eye-to-eye with a humpback mother whale swimming with her calf, it changed his life. He decided he wanted to recreate that experience for others by making a life-sized print of a whale -- something that had never been done before. So he quit his job, sold his house, and flew to the South Pacific armed with only a snorkel and a camera. Bryant Austin joins us to talk about his book, "Beautiful Whale," and his secret to getting within three feet of the mammals, without them swimming away. We'll also talk to a marine biologist about the efforts to protect whales.

Two years ago this month, the California Department of Parks and Recreation announced a list of 70 parks it planned to close. Park lovers rallied, giving their time and money to pick up the parks the state was willing to drop off. There is no closure list now, and the state parks are under new management, but the financial crisis has not passed. Those park lovers are now wondering how long they're going to carry the extra load.

Solar panels have sprouted up all over the sunny spots of California, but for industrial scale projects, there's no beating desert country -- if the price is right. Developers are cheering a decision by Riverside County officials on Tuesday to slash fees on new projects. Riverside could set a new standard for how local communities do business with big solar.
