Monarch butterflies make one of the most extraordinary migrations in the natural world, often traveling thousands of miles across North America. Now, scientists are using new tracking technology to get a greater understanding of those journeys. Ali Rogin speaks with Dan Fagin, a Pulitzer Prize-winning journalist who teaches science journalism at New York University, to learn more.

Some call it the 'Doomsday Glacier,' a vast expanse of Antarctic ice roughly the size of Florida. As temperatures rise, the Thwaites Glacier is melting fast and threatens to raise global sea levels. That's why a team of nearly 40 researchers is embarking on a two-month journey to study it. Science correspondent Miles O'Brien is with the expedition and reports.

This year, the development and spending around artificial intelligence has been perhaps the most significant business and economic story. AI spending is driving one of the most explosive periods for the tech industry and playing a big role in overall economic growth. But there are very real questions about the boom. Geoff Bennett discussed the potential bubble with Cade Metz of The New York Times. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast. See acast.com/privacy
In movies and literature, a wolf's haunting howl can signify danger or untamed nature. In real life, researchers in Yellowstone National Park are analyzing those howls with cutting-edge AI technology to better monitor and track wolves. Matt Standal of PBS Montana reports.

The Trump administration says it plans to dismantle the National Center for Atmospheric Research in Colorado, which is the nation's premier atmospheric science center. The center was founded in 1960 and has facilitated generations of breakthroughs in climate and weather science. William Brangham discussed the move with climate scientist Kim Cobb and meteorologist Matthew Cappucci. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast.

The Trump administration announced an immediate pause on the leases for five large-scale offshore wind farms off the East Coast. The Interior Department provided few details, but said the Pentagon believed the turbines could obscure and confuse radar signals. It's the latest move by the White House taking aim at wind power. Science correspondent Miles O'Brien has been tracking these projects. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast. See acast.com/privacy
President Trump has signed an executive order that would block states from enforcing laws they pass to regulate A.I., or artificial intelligence.The directive marks a big win for tech giants but will likely be challenged in the courts. Jacob Ward, founder of The Rip Current, joins Geoff Bennett to help break down the concerns and the arguments around all of this.

For years, solar power at home was mostly limited to people who owned their rooftops and could afford the steep upfront costs. But now, a new generation of small, affordable systems — often called "plug-in" solar — are making clean energy more accessible. Already widespread in Germany, the movement is gaining momentum in the United States. Laura Klivans of PBS member station KQED reports.

Last year, 1 in 10 U.S. babies was born before 37 weeks of pregnancy, which is considered preterm. That's one of the highest premature birth rates among developed nations, according to the March of Dimes. We hear from parents of preterm babies about their experiences, and Ali Rogin speaks with an entrepreneur who's using AI to help doctors predict when preterm births are likely.

So-called forever chemicals are both harmful to our health and are everywhere. Studies have found them in women's breast milk and even in rain falling in Tibet. A new book tells the story of how these extremely durable chemicals became so ubiquitous through the eyes of a small community that decided to fight for some measure of justice.

I am so happy to hear that wild polio is going extinct in another country! My mom's cousin got polio when she was young and now the damage it caused all those years ago is affecting her in her old age. Like wild chicken pox can come back as shingles, polio has long lasting effects.
