Big Picture Science for Mar 24, 2025: Disappearing Data

Big Picture Science: Disappearing Data

Firing federal workers and freezing grants has upended research institutions, prompting uncertainty about their futures. We look at the real-world impacts these policy changes may have for our mechanisms for collecting and sharing important data. An NIH grant recipient considers the future of her lab’s ability to do basic research, including studying complex diseases such as Alzheimer’s and heart disease. An interruption in reliable access to CDC data comes as highly contagious avian influenza continues to evolve and spread in the U.S. And what does the gutting of NOAA imply for collecting essential weather data, including those used to forecast hurricanes?

Guests:

• Kimberly Cooper – Developmental biologist at the University of California, San Diego
• Amy Maxmen – Public health reporter at KFF Health News
• Alan Sealls – Retired broadcast meteorologist, adjust professor at the University of South Alabama and president-elect of the American Meteorological Society

Big Picture Science for Mar 10, 2025: Preventable

Big Picture Science: Preventable

Two infectious diseases that we’ve been able to prevent for a half-century are re-emerging. One of the most contagious viruses in the world, measles, is spreading in the United States. Anti-vax sentiment has driven vaccination rates down leading to outbreaks in Texas and New Mexico. The U.S. has also seen an uptick in cases of tuberculosis which has reclaimed its position the deadliest infection globally. The author John Green shares how his travels to Sierra Leone inspired his new book about TB. Through the story of a young patient, Henry, he highlights the health inequities that contribute to over a million and a half tuberculosis deaths annually despite the existence of a cure.

Guests:

• Adam Ratner – Pediatric infectious disease doctor in New York City, and author of Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children's Health
• John Green – Author of The Fault in Our Stars, The Anthropocene Reviewed, and Everything is Tuberculosis: The History and Persistence of our Deadliest Infection

Big Picture Science for Mar 03, 2025: Your Mind On Movies

Big Picture Science: Your Mind On Movies

REPEAT
By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.

Guest:

• Walt Hickey - journalist, data scientist, and author of “You Are What You Watch: How Movies and TV Affect Everything”

Big Picture Science for Feb 24, 2025: The Latest Buzz

Big Picture Science: The Latest Buzz

REPEAT
Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and how can it be reversed.

Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds.

We investigate the small and the many on “The Latest Buzz.”

Guests:

• Martin Kernan – Historian and journalist. His article, “The Bug That Saved California,” appeared in the January-February 2022 issue of the Smithsonian
• Alessandra Mascaro – Evolutionary  Biologist, currently working at the Ozouga Chimpanzee Project, co-author of the Current Biology paper, “Application of insects to wounds of self and others by chimpanzees in the wild”
• Lara Southern – Doctoral student at the University of Osnabruck, co-author of the Current Biology paper, “Application of insects to wounds of self and others by chimpanzees in the wild”
• Oliver Milman – Environment correspondent for The Guardian in the U.S. and author of “The Insect Crisis: The Fall of the Tiny Empires that Run the World”

Big Picture Science for Feb 17, 2025: Skeptic Check: Into the DeepSeek

Big Picture Science: Skeptic Check: Into the DeepSeek

When the Chinese developer of DeepSeek released its model R1, a rift opened up in Silicon Valley. The company, a relatively unknown player, appeared to have created a better and cheaper model than its American competitors. Some big voices in the tech world called it a “Sputnik moment.” Others worried that the open-source model would allow malicious actors to harness the power of this AI technology. But did the arrival of DeepSeek significantly change how artificial intelligence will unfold? We explore that question and ask whether one particular sci-fi franchise got it right when portraying our anxiety about runaway AI.

Guests:

• Alex Kantrowitz – Tech journalist and founder of the podcast and newsletter Big Technology
• Kristian Hammond – Professor of computer science at Northwestern University and Director of the Center for Advancing Safety of Machine Intelligence
• Dorian Lynskey – podcaster and author of “Everything Must Go: The Stories We Tell About the End of the World”

Big Picture Science for Feb 10, 2025: Chasing an Asteroid

Big Picture Science: Chasing an Asteroid

Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We’ll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.

Guests:

• Scott Sandford - Astrophysicist and Research Scientist at NASA’s Ames Research Center
• Robin George Andrews - Science journalist, volcanologist, and author of "How to Kill an Asteroid: The Real Science of Planetary Defense"

Big Picture Science for Feb 03, 2025: Coming to Our Animal Senses

Big Picture Science - Coming to Our Animal Senses

REPEAT
Animals experience the world differently. There are insects that can see ultraviolet light, while some snakes can hunt in the dark thanks to their ability to sense infrared. Such differences are not restricted to vision: Elephants can hear subsonic sounds, birds navigate by magnetism, and your dog lives in a world marked by odors. In this episode, we speak to science journalist Ed Yong about how other creatures sense the world. Could we ever understand what it’s like to have the hearing of a bat or the sight of a hawk?

Guest:

• Ed Yong – Science writer for The Atlantic whose coverage of the COVID-19 pandemic earned him a Pulitzer Prize in explanatory journalism. He is the author of, “An Immense World: How Animal Senses Reveal the Hidden Realms Around Us.”

Big Picture Science for Jan 27, 2025: Skeptic Check: Drone Panic

 

Big Picture Science - Skeptic Check: Drone Panic

When several mysterious objects were spotted flying over New Jersey, their unknown identity led to frightening rumors, and triggered frustration and alarm among some residents of the Garden State. What were these objects, and if they were drones, as some appeared to be, were they friendly or foe? Many of the objects have now been identified. We talk about what happened when calmer heads prevailed and consider what the Great Drone Panic might have in common with other episodes involving objects cruising the skies. Also, why one expert thinks the event gave birth to a new UFO subculture.

Guests:

• Andrew Fraknoi - Professor of Astronomy at the Fromm Institute of the University of San Francisco
• Mick West - Investigator of conspiracy theories and UFO sightings
• Greg Eghigian - Professor of history and bioethics at Penn State and author of “After the Flying Saucers Came: A Global History of the UFO Phenomenon”

Big Picture Science for Jan 20, 2025: The Best Things in Life are Tree(s)

 

Big Picture Science - The Best Things in Life are Tree(s)

While humans were leaving the Stone Age and entering the Bronze, some Bristlecone pine trees grew from seeds to sprouts. They’ve been growing ever since. These 5,000-year-old pines are among the oldest organisms on Earth. Superlatives are also appropriate for the towering redwoods.

Trees are amazing in many ways. They provide us with timber and cool us with shade, they sequester carbon and release oxygen, and are home to countless species. But they are also marvels of evolutionary adaptation. We consider the beauty and diversity of trees, and learn why their future is intertwined with ours.

Guests:

• Kevin Dixon - Naturalist at The East Bay Regional Park District, Oakland, California
• Daniel Lewis - Environmental historian and senior curator for the History of Science and Technology at the Huntington Library, art museum and botanical gardens in Pasadena, California, professor of the natural sciences and the environment at Caltech, and author of “Twelve Trees: The Deep Roots of our Future”

Big Picture Science for Jan 13, 2025: The Ocean’s Genome

 

Big Picture Science - The Ocean’s Genome

REPEAT
After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.

Guests:

• Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”

Big Picture Science for Jan 06, 2025: Night Flight

 

Big Picture Science - Night Flight

REPEAT
Owls are both the most accessible and elusive of birds. Every child can recognize one, but you’ll be lucky to spot an owl in a tree, even if you’re looking straight at it. Besides their camouflage and silent flight, these mostly nocturnal birds, with their amazing vision and hearing, are most at home in the dead of night, a time humans find alien and scary. Ecologist Carl Safina got to know an injured baby screech owl well. Their relationship saved the owl’s life and gave Safina insider’s wisdom about these aerial hunters of the night.

Guests:

• Carl Safina – ecologist at Stony Brook University, head of the non-profit Safina Center, and author of “Alfie & Me: What Owls Know, What Humans Believe”
• Tom Damiami – natural resources interpreter, singer on Long Island, NY and leader of the Shelter Island Owl Prowl

Big Picture Science for Dec. 30, 2024: Skeptic Check: Naomi Klein

Big Picture Science - Skeptic Check: Naomi Klein

REPEAT
Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.

Guests:

• Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror World
• Lee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.

Big Picture Science - 2024: Extraordinary Ordinary Objects

REPEAT
“To live is to count and to count is to calculate.”  But before we plugged in the computer to express this ethos, we pulled out the pocket calculator. It became a monarch of mathematics that sparked a computing revolution. But it’s not the only deceptively modest innovation that changed how we work and live. Find out how sewing a scrap of fabric into clothing helped define private life and how adding lines to paper helped build an Empire. Plus, does every invention entail irrevocable cultural loss?

Guests:

• Keith Houston – author of “Empire of the Sum: The Rise and Reign of the Pocket Calculator.”
• Hannah Carlson – teaches dress history and material culture at the Rhode Island School of Design, author of “Pockets: An Intimate History of How We Keep Things Close.”
