In 1972, pandas arrived at the Smithsonian’s National Zoo in Washington, DC, to huge fanfare. Since then, pandas have been some of the city’s most beloved residents.But for the first time in more than 50 years, DC is panda-free—indefinitely. Mama panda Mei Xiang, papa bear Tian Tian, and their youngest cub Xiao Qi Ji returned to China in November when their leases ended. This is possible because all but a few pandas residing outside of China are on loan through agreements with the country.It’s not just the National Zoo waving its pandas goodbye—the Memphis Zoo’s single panda returned to China in April, and Zoo Atlanta’s pandas will go later in 2024. The news of the pandas’ departure seemed sudden, and it stirred up some questions: Why are the pandas leaving? And why now?The news resurfaced the idea of panda diplomacy—how China introduced pandas to the world by loaning them out to other countries and using them as a symbol of cooperation.SciFri producer Rasha Aridi and freelance journalist Aja Drain look back at 80 years of panda conservation, and how panda diplomacy paved the way for groundbreaking science. And they try to answer the multi-million dollar question: Was it all worth it?This story was produced by Rasha Aridi, with help from Aja Drain. Edited by John Dankosky, with help from D. Peterschmidt and Emma Gometz. All our music and sound design is by D.

It can be hard to avoid the chime of classic Christmas songs at this time of year. Certain songs may even bring up potent memories, transporting a person to a specific moment in the past, like an afternoon baking cookies as a child, or warming up after playing in the snow.Music, when coupled with emotion, has the ability to create powerful memories. And listening to songs associated with specific memories can almost feel like going back in time.Better understanding how this mechanism works is the work of Assistant Professor Dr. David Clewett and PhD candidate Mason McClay, both in UCLA’s cognitive psychology department. They talk with SciFri producer Kathleen Davis about how this method could be used to improve therapies for PTSD and other memory disorders.Transcripts for this segment will be available the week after the show airs on sciencefriday.com.

The Top Science News Stories of 2023As the year comes to a close, we wanted to reflect on some of the top science stories of 2023: Scientific breakthroughs that will shape our lives in 2024 and beyond. Research that’s shifted how we understand the universe. And even a story or two that put a smile on our faces.In 2020, the story of the year was the rapid development of COVID-19 vaccines. And while there are now updated versions of those, vaccine development has gone much further. This year we saw approval of two exciting new vaccines, for RSV and malaria.SciFri’s director and senior producer Charles Berquist talks with Sophie Bushwick, incoming senior news editor at New Scientist about this years vaccine breakthroughs and other top science news of the year, including a new generation of weight loss drugs, record high temperatures, completion of the human pangenome, an asteroid sample’s arrival on Earth, ripples in space-time, AI to understand pets’ emotions and T. rex’s new smile.Solar Panels In Historic Cape Cod: Who Decides Where ‘Modern’ Fits?Cape Cod is home to one of the largest historic districts in the country. In the 80 square miles that make up the Old Kings Highway Historic District, the goal of preservationists is to maintain a certain look. So from Sandwich to Orleans, some 45,000 people who live north of Route 6 are required to get approval from local historic committees for solar installations that are visible from a public way. Over the last few decades, many property owners who’ve had their solar plans challenged or denied have described the committees’ decisions as inconsistent, arbitrary, and subjective.But the committees remain steadfast: tourists and locals alike love seeing historic buildings preserved. And solar panels on the front of a house can read like billboards for modernity.“When you start messing with the street view of your house, we have a legal right, on behalf of the public, to make a judgment of the appropriateness of it,” said Jim Wilson, administrative counsel for the Old Kings Highway Regional Historic District Committee, which sets standards and hears appeals of rulings by town committees.The preservationists’ mandate is only to approve solar panels on homes when they present a minimal visual impact on the neighborhood. And that standard is often the source of the argument: what defines a minimum visual impact?Read the full story at sciencefriday.comTranscripts for each segment will be available after the show airs on sciencefriday.com.
