Scientists use new technology to track individual monarch butterfly migrations

So you want to change a habit — or maybe start something new. Pulitzer Prize-winning journalist and author Charles Duhigg's book, "The Power of Habit," explores how habits are made, and the cues and rewards that shape our behavior. He spoke with Amna Nawaz about how to make habits that actually stick as well as his most recent book, "Supercommunicators." PBS News is supported by - https://www.pbs.org/newshour/about/funders.

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.

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.
