It's Tax Day! In these challenging economic times, and in the wake of massive bank bailouts and several of Obama's cabinet nominees who took tax missteps, people may be fishing for an excuse not to pay all of their taxes. For a primer on what motivates us to cheat—and what keeps us honest—we are joined by behavioral economist Dan Ariely. He is the James B. Duke Professor of Behavioral Economics at Duke University and author of Predictably Irrational.

The world is now spending billions of dollars investigating the causes of climate change. Scientists are quickly putting together physical and biological experiments and projects, hoping for solutions and models that will show us how to slow warming and save the planet. But there's another body of work underway that's focused on the human brain. This research argues that climate change policy and solutions for global warming won't be worth much until we know how to influence the individual decisions that cause global warming. To help us figure out why it is so hard to get our brains to choose green options we are joined by Jon Gertner, a contributing writer for the New York Times Magazine. His article on this will be available in the Times Magazine on Sunday.

Maybe this is a case for Captain Planet:

Researchers in Glasgow have developed an early warning sunburn indicator. A thin paper strip or sticker, filled with "intelligent ink," will turn pink after too much exposure to ultra-violet light. The device is easy to use, too: Before heading to the beach, strap on the bracelet or sticker and when you see it turn pink, it is time to put on a shirt or head indoors. The strips are inexpensive enough for frequent use and researchers are hoping to test the prototype this summer. We're learning more about this shiny new development with Andrew Mills, professor at Strathclyde University, who helped to create these sunburn wristbands.

A new report from The Sentencing Project reveals a changing demographic of prisoners who are incarcerated for drug charges. The report shows that for the first time in 25 years, since the start of the so-called War on Drugs, incarceration rates for black men has dropped. The report shows that over a six-year period, the rate of black men in jail on drug-related charges dropped 21% while the imprisonment for white men spiked by 42%. Is this racial disparity a sign of the changing prison demographic? To guide us through what these numbers mean, The Takeaway is joined by David Fathi, director of Human Rights Watch in the U.S.

President Barack Obama has made clear that he views Cuban Americans as “Ambassadors of Democracy” who can bring a message to Cuba when they visit their families there. But what do Cuban-Americans think? Are they excited at this new patriotic title bestowed on them? Or glad to be able to trace their roots back to the island nation? Are they unwilling to return to Cuba while the Castros are still in power? Or are they just happy to have another beach to visit? This morning we are listening to the response from younger Cuban-Americans who were born here in the U.S. and never personally knew life under Castro or in Cuba. The Takeaway talks to Danny Mendoza, a filmmaker and student at New York University’s Tisch School of the Arts.

U.S. Special Envoy to the Middle East George Mitchell arrives in Israel today as part of his two-week tour of the Middle East and North Africa. Against the backdrop of Israel's three week offensive in Gaza to root out Hamas militants, Mitchell has announced he is pushing a two-state solution to the Middle East conflict and during his trip he has been enlisting broad Arab support for his plan. But how important is it to have Arabic support for plans for peace in Israel? To help us answer that question, we turn to Rosemary Hollis. For ten years, Ms. Hollis was the head of the Middle East program at Chatham House—a leading international affairs think tank. She is now Director of the Olive Tree Programme at London's City Universtiy.

In the past fifty years, wealthy nations including the U.S. have given $1 trillion in aid to the continent of Africa. And yet, many African countries remain mired in poverty. So is it time to rethink aid to Africa? The Takeaway talks to Dambisa Moyo an economist and author of the book Dead Aid: Why Aid is not Working and How there is a Better Way for Africa. We are also joined by Lynn Sherr, journalist and Africa correspondent for PBS's World Focus.

In the last five years, Liberia has made the transition from Charles Taylor, a warlord accused of hate crimes, to Ellen Johnson Sirleaf, the first woman democratically elected to lead an African nation. It's a change that has made Liberia a focal point for the advancement of women in Africa and worldwide. Ellen Johnson Sirleaf is now coming to the U.S, and releasing a book about her life, This Child Will Be Great. She's also just been interviewed by Lynn Sherr, special correspondent for World Focus on PBS.
