After months of negotiations, a bipartisan group of senators plan to release details of an immigration deal. Now, lawmakers must decide if they'd rather have the political issue or the policy solution.

This episode: senior White House correspondent Tamara Keith, national political correspondent Mara Liasson, and the Texas Newsroom's capitol reporter Sergio Martinez-Beltrán.

Every year, lightning is estimated to cause up to 24,000 deaths globally. It starts forest fires, burns buildings and crops, and causes disruptive power outages. The best, most practical technology available to deflect lightning is the simple lightning rod, created by Benjamin Franklin more than 250 years ago. But lightning rods protect only a very limited area proportional to their height. In today's encore episode, we explore why a group of European researchers are hoping the 21 century upgrade is a high-powered laser. Plus: Regina makes incremental progress on conquering her irrational fear of lightning.

When the U.S. government and state of Florida unveiled a new plan to save the Everglades in 2000, the sprawling blueprint to restore the wetlands became the largest hydrological restoration effort in the nation's history. Two decades later, only one project is complete, the effort is $15 billion over budget and the Everglades is still dying. The new podcast Bright Lit Place from WLRN and NPR heads into the swamp to meet its first inhabitants, the scientists who study it and the warring sides struggling to find a way out of the muck. Today, we hear an excerpt as environment reporter Jenny Staletovich tags along with wetlands ecologist Evelyn Gaiser to the remotest part of the swamp.

At the Ol Pejeta Conservancy, a wildlife preserve in central Kenya, lions and cheetahs mingle with zebras and elephants across many miles of savannah – grasslands with "whistling thorn" acacia trees dotting the landscape here and there. Twenty years ago, the savanna was littered with them. Then came invasive big-headed ants that killed native ants — and left the acacia trees vulnerable. Over time, elephants have knocked down many of the trees. That has altered the landscape — and the diets of other animals in the local food web.

Scientists know that Black people are at a greater risk for health problems like heart disease, diabetes and Alzheimer's disease than white people. A growing body of research shows that racism–in health systems and the effects of experiencing racial discrimination–contributes to these long-standing health disparities for Black communities. Now, some researchers are asking whether part of the explanation involves how racism changes the brain.

Today on the show, science correspondent Jon Hamilton speaks with Nate Harnett, an assistant professor of psychiatry at Harvard Medical School, and Negar Fani, a clinical neuroscientist at Emory University about how experiencing racism may change the brain.
