A phenomenon called the Polar Vortex is responsible for one of the nation's coldest periods in two decades. David Greene talks to Andrew Freedman, senior science writer for Climate Central, an independent non-profit organization researching and reporting on the science and impacts of climate change.
European scientists were alarmed in 2008 when they discovered streams of methane bubbles erupting from the seafloor in Norway's high Arctic. This gas, which contributes to global warming, was apparently coming from methane ice on the seafloor. A follow-up study finds that methane bubble plumes at this location have probably been forming for a few thousand years, so they are not the result of human-induced climate change. But continued warming of ocean water can trigger more methane releases in the Arctic, with potentially serious consequences to the climate.
Say a child has memories of being a Hollywood extra in the 1930s. Is it just an active imagination, or actual evidence of reincarnation? Jim Tucker, a psychologist at the University of Virginia studies hundreds of cases like this and joins NPR's Rachel Martin to share his research on the science behind reincarnation.
There you are in a train station, and if you stand in the right space, suddenly an angel — a lady with enormous wings, looking like the real deal — appears at your side. She's not real. She's a billboard display gone wild. Which is what a bunch of billboards have been doing lately. We visit three of the wildest.
Students at Rice University in Houston are finding low-cost solutions to big global health problems. The women running the program are hoping to get these young engineers hooked on helping. One particularly successful device that helps infants breathe has already been tested in Malawi and will be distributed to hospitals around the country.
