New Horizons Discovery, Science Fair Finalists, Screams. May 17, 2019, Part 2

The most happening New Year’s Party of 2019 wasn’t at Times Square or Paris—it was in the small town of Laurel, Maryland, halfway between Baltimore and Washington, D.C., at the Johns Hopkins University Applied Physics Lab. There, scientists shared the stage with kids decked out in NASA gear, party hats, and astronaut helmets. They were there to count down not to the new year, but to the New Horizons spacecraft flying by a very distant, very ancient, snowman-shaped object: MU69.Now, the first haul of data about that mysterious object has returned. They reveal that MU69 is one of the reddest objects we’ve explored in the solar system, built from two skipping-stone-shaped bodies, each the size of small cities. Those details are featured in a cover story in the journalScience. Lead author Alan Stern joins Ira here to talk about it. This week, more than 1,800 student scientists from 80 countries converged in Phoenix to present their projects for Intel’s International Science and Eng...

Degrees Of Change: Sea Level Rise, Coal-Use Decline. May 17, 2019, Part 1

As the frequency of tropical storms and droughts increase and sea levels rise with climate change, forested wetlands along the Atlantic coast are slowly filling with dead and dying trees. The accelerating spread of these “ghost forests” over the past decade has ecologists alarmed and eager to understand how they are formed and what effect they will have regionally and globally. One interdisciplinary group of researchers from North Carolina State University and Duke University are examining the causes and effects of repeated saltwater exposure to the coastal wetlands of North Carolina. Using soil and sediment sampling, remote hydrological monitoring, vegetation plotting, as well as spatial maps, the research team is determining the tipping point for when a struggling forest will become a ghost forest. According to ecologist Emily Bernhardt, their preliminary findings suggest that climate change is not the only culprit in the region. Agricultural irrigation and wastewater ditches th...

Biodiversity Report And The Science Of Parenting. May 10, 2019, Part 2

According to a new UN report on global biodiversity, as many as one million species—both plants and animals—are now at risk of extinction, according to a new UN report on global biodiversity. That number includes 40% of all amphibian species, 33% of corals, and around 10% of insects. One might assume that this type of devastating species loss could only come as a result of one thing—climate change. But in fact, as the report highlights illustrate, it’s deforestation, changes in land and sea use, hunting, poaching, pollution, invasive species—in short, human interventions—that are causing species to disappear at a rate tens to hundreds of times higher than what has been seen over the last 10 million years.Walter Jetz,professor in ecology and evolutionary biology at Yale University, joins Ira to discuss why the damage we do to biodiversity in our lifetimes may never be undone. Plus, if you're a new parent,you’ve probably had one ofthese nights. You’re up at 3 a.m., baby scream...
